How to apply for the business license of block asphalt melting equipment?

For users of equipment, the amount of material used is the focus of every user. We should attach great importance to this link in the production process. The following is an analysis of the amount of emulsifier used by Gaoyuan manufacturers.
When emulsified asphalt equipment is emulsifying asphalt, the asphalt temperature is better controlled at above 130°C to have better fluidity; 2. The amount of emulsifier is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is more than 50%), and the temperature is 60-70°C. The emulsifier should be used in the middle and upper limit of the production, 10 kg per ton of emulsified asphalt, or 20 kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is more than 50%), and the emulsifier solution temperature is 60-70°C. The emulsifier should be used in the upper and middle limits in the first production to ensure successful production. Use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

The selection of asphalt melting equipment should take into account factors such as the use environment, working conditions, and technical requirements. Common ones include hot oil heating equipment, electric heating equipment, and gas heating equipment.
Hot oil heating equipment is suitable for occasions that require long-term heating and high temperature control accuracy;
Electric heating equipment is suitable for small projects or occasions where temperature control accuracy is not required;
Gas heating equipment has the advantages of simple operation and low cost, but safety protection measures must be strictly followed.
When choosing, it is also necessary to comprehensively consider factors such as economy and environmental protection.

The engine is the source of power for the vehicle. If the synchronous sealing vehicle wants to perform normal construction operations, it must ensure that the engine is in good condition. Routine maintenance is an important means to effectively prevent engine failure. How to maintain it is determined by Xinxiang Junhua Special Vehicle Vehicles Co., Ltd. will take everyone to understand.

Emulsified asphalt is an aqueous suspension of asphalt particles with high interfacial energy. This suspension state is thermodynamically unstable and has the potential to reduce its interfacial area (i.e., through the coagulation process) to a stable state. Preventing this coagulation state (dispersion destruction) is the stabilization effect of the emulsifier protective layer. The stability of emulsified asphalt refers to the ability of asphalt particles to aggregate and cause phase separation, and also refers to the time required for emulsified asphalt to reach equilibrium. That is, the time for asphalt particles to aggregate and separate from water. How can we increase this time? How to prevent emulsified asphalt from demulsifying?

There are many types of emulsified asphalt (composition: asphaltene and resin) equipment. Emulsified asphalt (composition: asphaltene and resin) equipment can be divided into intermittent operation type, semi-continuous operation type, and Continuing the three operating types, what is the knowledge about different types of emulsified asphalt equipment?

There is a wide variety of asphalt melting equipment on the market, including different brands and models. The prices of these devices vary widely, depending mainly on factors such as their features, performance, and specifications.
Asphalt melter equipment produced by some large brands such as Sinoroader usually has higher quality and reliability, so the price is relatively higher. However, they also offer longer service life and better maintenance support.

Improve the understanding of the importance of preventive maintenance
We should further improve the understanding of the importance of preventive maintenance and raise preventive maintenance to the level of highway asset protection and road protection. At present, leaders at all levels and maintenance departments do not fully understand the significance of preventive maintenance of asphalt pavement. We should deepen our understanding of the important role of preventive maintenance and improve the strategic awareness, initiative and creativity of preventive maintenance. At the same time, the maintenance department should strengthen communication and exchanges with transportation authorities and financial management departments at all levels, so that departments at all levels understand the importance and necessity of preventive maintenance and create conditions for the implementation of preventive maintenance and funding sources. At the same time, it is very necessary to add preventive maintenance to the classification of maintenance projects, which will help the management of leaders at all levels and the implementation of preventive maintenance.
Improve the decision-making and planning of preventive maintenance
According to the decision-making and planning process, reasonably arrange the preventive maintenance of asphalt concrete pavement structure to ensure the safe and stable operation of highway projects throughout the life cycle, and reduce production costs while providing high-quality traffic services. Therefore, the key to preventive maintenance of asphalt concrete pavement structure lies in establishing a scientific decision-making and planning mechanism. The Ministry of Transport proposed in the “13th Five-Year Plan for Highway Maintenance Management Development” that the average annual mileage of preventive maintenance for expressways should not be less than 8%, and that for ordinary national and provincial roads should not be less than 5%. In the actual application process, local governments should also actively summarize experience and propose different preventive maintenance ratios based on the specific conditions of different regions.

Based on the characteristics of the high-speed hot mixed bitumen melting equipment, the direct heating bitumen melter equipment tank is a researched, environmentally friendly and energy-saving thermal mixed bitumen melting equipment, which can directly coordinate the temperature of the direct heating bitumen melter heating tank and protect the direct heating asphalt melter equipment. Barrel heating tank. The temperature of hot mixed asphalt barrels achieves the appropriate storage temperature.
When the water level in the drum is lower than the temperature of the thermometer, please close the suction valve before the drum pump is shut down to prevent the drum from flowing back in the heater. After the motor has been running for 2 days, the three-way valve opens quickly.

Emulsified asphalt can be spread by mechanical spreading and manual spreading. Different spreading methods will have different effects on pavement performance, so it is very important to choose the right spreading method. At the same time, maintenance and management after spreading are equally important to ensure the safety and durability of the pavement.
Emulsified asphalt is a common pavement material that is widely used in road construction and maintenance. There are two main ways to spread emulsified asphalt: mechanical spreading and manual spreading. Mechanical spreading generally uses a special spreading vehicle that can quickly and evenly spread emulsified asphalt. Manual spreading is carried out by workers using tools such as brushes or rollers, which is suitable for pavement treatment in small areas or special areas.
Different spreading methods also have different effects on pavement performance. Mechanical spreading can quickly complete large-area treatment and spread evenly, which is conducive to ensuring the flatness and anti-skid properties of the pavement. Manual spreading can more finely treat special areas such as shoulders and intersections to improve the overall performance of the pavement.

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.

How to reduce the energy consumption of emulsified asphalt production equipment is a concern of many users, and is also an issue that many manufacturers attach great importance to. Therefore, today Sinoroader, as a manufacturer of emulsified asphalt production equipment, would like to take this opportunity to share with you how to reduce the production of emulsified asphalt. Equipment energy consumption method.
Since emulsified asphalt appears as a finished product in emulsified asphalt production equipment, and the outlet temperature of ordinary emulsified asphalt is about 85°C, the outlet temperature of emulsified modified asphalt is above 95°C, so there is a lot of latent heat in emulsified asphalt, but emulsified asphalt The production equipment does not make good use of them, but directly enters the finished product tank, allowing the heat to be lost at will, resulting in a waste of energy.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

Emulsified asphalt is an emulsion that disperses asphalt into the water phase to form a liquid at room temperature. This determines that emulsified asphalt has many technical and economic advantages over hot asphalt and diluted asphalt. We know that modified asphalt equipment is a road engineering machinery. In order to better promote users’ understanding of it, today the editor will introduce its characteristics to you so that users can better understand that modified asphalt equipment is used for modified asphalt. It consists of a main machine, a modifier feeding system, a finished product tank, a heat transfer oil reheating furnace and a microcomputer control system. The main machine is equipped with a mixing tank, a dilution tank, a colloid mill and an electronic weighing device. The entire production process is controlled by a computer automatic program. In addition, it can be learned that the product has the advantages of reliable quality, stable performance, accurate measurement, and convenient operation. It is an indispensable new equipment in highway construction. The advantages of asphalt equipment are prominently reflected in its two-way modification effect, that is, while greatly increasing the softening point of asphalt, it also significantly enhances the low-temperature ductility, improves the temperature sensitivity, and has a particularly large elasticity and recovery rate. The modified asphalt equipment has a long service life and a safe and reliable production process. The rotor and stator are specially heat treated, and the service life of the equipment is more than 15,000 hours.

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first use the modified asphalt equipment safely to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Sinoroader will explain it in detail:
1. Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure that the machine does not move around during operation.
2. Check regularly whether the mixer blades are deformed and whether the screws are loose.
3. Check whether the running direction of the mixing barrel is consistent with the arrow. If not, please replace the positive and negative poles of the wiring.
4. Before powering on, check for empty vehicle trial operation, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, stop the car for verification.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water, remember that there must be no water in the bucket to prevent the formula from changing, and even rust on the pages and other links. During use, everyone should pay attention to some small links to avoid unnecessary losses in their work.

With the continuous improvement of science and technology in my country, the application and popularization of bitumen emulsion equipment are also increasing. So how to check whether the configuration meets the standards? Only products that meet the standards can bring us benefits. We must pay attention to this issue. Next, please have a detailed understanding with our factory staff:
1. First of all, we need to check the modified emulsifier. If the gap between the bitumen emulsion colloid mill of the emulsifier will become larger during operation, we need to adjust it before continuous production;
2. Analyze the problem of the modifier. Under normal circumstances, we need to check whether the amount of modifier added is accurate. The time of addition should also adjust the pH value according to the difference in water quality used. This work needs to be operated by technical personnel;
3. Another major reason is caused by the problem of the bitumen emulsion configuration itself. When producing bitumen emulsion, it is necessary to check in advance whether the bitumen material used meets the quality standards.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

During the use of emulsified bitumen equipments, if maintenance is not paid attention to, the cycle will be short, and problems will often occur during use. Only by doing a good job of maintenance can the operation efficiency of the equipment be improved. For example, during maintenance, the following points must be grasped.
It is necessary to regularly check the wear condition of the internal structural components of the mechanical equipment, such as the core feed pipe, the rough jaw plate on the impeller, the cone cap, the wear level of the jaw plate, the rain shield on the circle, and the wear condition. If the wear is more serious, it is necessary to replace or repair it in time. When replacing, it is also necessary to pay attention to the model and specifications, and replace it according to the original components as a reference.

In the cold winter, the following points should be noted when using bitumen melter equipment:

1. Keep warm: The bitumen melter equipment needs to be operated indoors or in a place with sunshade facilities, and ensure that the temperature of the bitumen melter and the surrounding environment is kept within an appropriate range.
2. Check the bitumen melting equipment: Before use, the bitumen melter should be checked, including whether the circuit, liquid circuit and other parts of the equipment are working properly, and whether the equipment has leakage, water leakage and other conditions.
3. Pay attention to safety: During operation, protective bitumen melter equipment should be worn to avoid direct contact with hot bitumen. At the same time, avoid overloading the bitumen melter to prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the bitumen melting equipment according to weather conditions and road conditions to avoid overheating of the equipment, which may cause the bitumen to flow too quickly or burn.
5. Storage conditions: When not in use, place the equipment in a dry, ventilated and moderately warm place, and ensure that the residue in the equipment is completely cleaned.

After the rubber bitumen storage tank is cleaned, the wood chips are sent to the rubber bitumen storage tank, and the wood chips and the bottom of the rubber bitumen storage tank are wiped with wood chips. The dirt and wood chips in the bitumen tank can be weathered naturally. The rubber bitumen storage tank is not allowed to be damaged. Check the technical specifications of the underwater concrete processing equipment and ventilation equipment.
The bottom of the rubber bitumen storage tank drain pipe is discharged from the drainage pipe, and the waste water is discharged into the empty tank or other containers through the inlet and outlet and the self-draining pipe. Open the Shenzhen manhole into the plastic suction pipe and pave the Shenzhen manhole with asbestos to reduce the discharge of oil and gas. When manually pumping the bottom oil, two people should be operated to improve the labor efficiency of the workers and send the fuel tank to supervision.

Asphalt spreader is an irreplaceable tool for highway maintenance. Asphalt spreader is an irreplaceable tool for highway maintenance. Highway maintenance is divided into four categories according to the nature of the project, scale, and technical complexity: minor repair, medium repair, major repair, and improvement. Specific classification:

Emulsified asphalt (ingredients: asphaltene and resin) heating tank is a new type of equipment for heating emulsified asphalt. Its appearance replaces the traditional thermal oil heating equipment, which brings great convenience to our users and improves work efficiency. Then let’s take a detailed look at how it is better than the traditional thermal oil heating equipment.
Emulsified asphalt (ingredients: asphaltene and resin) heating tank is another new type of emulsified asphalt heating storage equipment developed by technically separating the characteristics of traditional thermal oil heating emulsified asphalt tanks and internal heat part (part) rapid emulsified asphalt heating tanks. The automatic circulation program of the asphalt heating equipment enables the asphalt to automatically enter the heater, dust collector, induced draft fan, asphalt pump, asphalt temperature display, water level display, and steam generator as required.
It consists of pipeline and asphalt pump preheating system, pressure relief system steam combustion system, tank cleaning system, oil unloading tank installation, etc. All are installed on the tank body (inside) to form a compact integrated structure. It fully compensates for the shortcomings of traditional thermal oil heating equipment, such as long heating time and high energy consumption.

This set of mechanical equipment includes wastewater treatment, water storage tank, automatic water measurement and verification temperature control system, asphalt storage tank, asphalt external temperature system, hot water pump soap condiment system, soap storage tank, soap mixing pump, soap external It is composed of temperature system and measurement verification system, filtration system, hot asphalt mixing pump and measurement verification system, three-stage pipeline-type black antistatic medical tweezers, emulsified asphalt cooling system and retrieval machinery, and automatic control system for commercial tanks and electrical equipment.

Due to the incorporation of a certain proportion of water into the slurry sealing mixture, it is easy to evaporate in the air. After the water is evaporated, it will become dry and hardened. Therefore, after the slurry is formed, it not only looks very similar to fine-grained asphalt concrete, but does not affect the visual appearance of the road. It also has the same technical properties as fine-grained concrete in terms of wear resistance, anti-skid, waterproofing, and smoothness. Slurry seal technology is used in highway pavement maintenance because of its simple construction technology, short construction period, low cost, high quality, wide application, strong adaptability, etc. It is an asphalt with both economy and high efficiency. Pavement maintenance technology is worthy of application and promotion.

With the rapid development of highway construction and the increase in demand for asphalt, barreled bitumen has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported bitumen used in high-grade highways is in barrel form, which requires an bitumen melter equipment with fast melting speed, clean debarreling, and prevention of asphalt aging.
The upper part of the debarreler of the bitumen melter equipment is hotter, and each barrel is directly heated by the heat transfer oil coil. The barrel wall directly bears the heat radiation of the heating coil. The asphalt is cleanly and sensitively debarreled, and there will be no waste of asphalt hanging barrels. According to the principle of layered heating, four-layer heating technology is adopted, with single inlet and single outlet of heat transfer oil, and high thermal efficiency of heating; at the same time, the waste heat of combustion exhaust gas is used for secondary heating, and power is effectively used; the debarreler body is insulated with high-quality rock wool material. It is suitable for various types of imported and domestic barrels, and the deformation of asphalt barrels will not affect production.
