Do you know what the bitumen colloid mill is used for?

We need to prepare a lot of work when using modified asphalt equipment. What kind of work do we need to prepare? Next, let me briefly introduce the relevant knowledge points.
1. Heat transfer oil heats and insulates the modified asphalt equipment and nozzle. After spraying, the asphalt pump and nozzle do not need to be cleaned with diesel. Use high-pressure air to press the asphalt in the pipeline and spray pipe back to the tank, and then blow the nozzle; use heat transfer oil to keep warm, so that the pipeline and nozzle are smooth and unobstructed. 2. Various asphalts can be spread: high-viscosity asphalt, hot asphalt, emulsified asphalt, etc.; the spreading width can be freely adjusted, each nozzle can be controlled separately, and the maximum spraying width is up to 6m. Flexible handheld spray guns can be used to spray asphalt on corners. 3. Excellent thermal insulation performance, average cooling ≤1-2℃/h. 4. Convenient loading and unloading function. In addition to filling asphalt from the asphalt tank port, hot asphalt can be sucked out by itself, and external asphalt can also be pumped and transferred. 5. The modified asphalt equipment is evenly spread, and the nozzle design can be used for triple overlapping spraying.
The above are the relevant knowledge points of modified asphalt equipment. I hope the above content can be helpful to everyone. Thank you for your viewing and support. More information will be sorted out for you later. Please pay attention to our website updates.

Modified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of modified asphalt equipment in order to fully demonstrate its performance. So how much do you know about the safe use and operation of modified asphalt equipment? Today, Gaoyuan Road Construction 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 suspended 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, you should stop and check.
5. If the machine is stopped for more than one hour after the asphalt mixing is completed, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing and even rusting of the pages and other links.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

Bitumen emulsion equipment is widely used in new technologies and new processes for preventive maintenance. Bitumen emulsion plant is an emulsion at room temperature formed by dispersing bitumen into the water phase. It is a new material that is made of natural materials. It is different from traditional Compared with hot bitumen, it saves more than 50% of energy, saves 10%-20% of bitumen, and causes less pollution.

The requirements for SBS asphalt emulsification equipment are very high. The micro powder machine must have a sufficiently large driving force and can bear the condensation type. Because the temperature requirements of the emulsion SBS asphalt process are relatively high, the emulsified asphalt should be passed through a heat exchanger before feeding to reduce the emulsified asphalt temperature to below 90°C to prevent the emulsified asphalt from breaking due to excessive temperature.
The application scope of SBS modified emulsified asphalt is very wide. According to the nature of the construction, it can be used in new construction, renovation, and reconstruction projects; according to the nature of the project, it can be used in overhaul, equipment overhaul, and maintenance projects. Among them, the actual application projects include micro-surfacing, cold regeneration, cold mixing and cold paving, adhesive layer, permeable oil, slurry seal, gravel permeable layer, fog permeable layer, road moisture-proofing, SBS membrane, ground seam filling, and all other projects that can use emulsified asphalt.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

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.

Colored asphalt pavement is a kind of special pavement material that mixes colored particles into asphalt and then lays on the pavement

Reasonable preventive maintenance can not only extend the life of the road, but also improve driving safety and comfort.

According to the configuration, layout and controllability of bitumen melting equipment, bitumen melting plant can be divided into three types: mobile, transportable and portable. What should be paid attention to in the production of bitumen melter equipment of different sizes? Let’s learn about it below!
Bitumen melting plant is to fix the demulsifier mixing equipment, black anti-static tweezers, asphalt pump, automatic control system, etc. on a special support chassis. Because the bitumen melter equipment can directly change the production site, it is suitable for the production of emulsion bitumen in construction sites with decentralized projects, small usage and frequent movement.
The main components of the bitumen melting equipments are installed in one or two 60 standard containers. The bitumen melting plant is loaded and transported separately to complete the relocation of the construction site. With the help of asphalt melting equipments hoisting equipment, it is quickly installed and put into operation. Such bitumen melter plant has large, medium and small different configurations, which can meet different project requirements.

With reliable performance and stable benchmark quality, Sinoroader slurry sealer is favored by customers and was once in short supply. Sinoroader slurry sealer uses emulsified asphalt, which can reduce the sensitivity of construction temperature and effectively extend the construction time. Sinoroader slurry sealer has fast molding, improves construction speed, shortens road construction time, and reduces the manpower and material resources required for construction. In addition, in terms of energy saving and consumption reduction, Sinoroader slurry sealer can be constructed at room temperature, achieving “0 release” of harmful gases, reducing air pollution, and is very green and environmentally friendly.

When performing bitumen melting, specialized equipment is required. These equipment usually include bitumen melting furnaces, asphalt mixers, asphalt conveying equipment, etc. Among them, the bitumen melting furnace is one of the most advanced equipments, which can heat solid bitumen to liquid state. In addition, asphalt mixers can mix liquid asphalt with stone to make asphalt concrete. , Asphalt conveying equipment can transport asphalt concrete to the construction site. The selection and use of these equipment are of great significance to ensure the quality of bitumen melting and construction efficiency.

The application of slurry mixes in highways and municipal engineering projects is of significant importance and widespread practicality. The following is a detailed analysis of their applications in these two areas:
I. Highway Applications
1. Applications of Colored Polymer Slurry Mixtures
Advantages: A variety of colors, environmentally friendly and durable, easy application, fast curing, and wear and skid resistance.
Applications: Colorful highway pavement designs, such as the Beijing-Dezhou Expressway, utilize colored polymer slurry mixes for their pavement design. This creates a visual impact for drivers, relieves fatigue, and serves as a warning.
Effects: Improves the aesthetics and safety of highways, providing drivers with a more comfortable and safe driving environment.
2. Applications of Slurry Seals
Types: Slurry seals primarily include slurry seals and micro-surfacing.
Advantages: Excellent anti-skid properties, waterproofing and anti-seepage properties, rapid application, and cost-effectiveness.

Emulsified modified asphalt equipment includes sewage treatment, water storage tank, water metering and verification temperature control system, asphalt storage tank, asphalt external temperature control system, hot water pump soap seasoning system, soap storage tank, soap mixing pump, soap external temperature control system and metering and verification system, filter, hot asphalt mixing pump and metering and verification system, pipeline black anti-static tweezers, emulsified asphalt cooling system and retrieval equipment, product tank and electrical control system.
The whole set of procedures is modularized, and customers can freely match and use according to their needs. The application of each part of the equipment is as follows: Sewage treatment system: Mechanically filter and adsorb the general drinking water to react with epoxy resin to convert the strong drinking water into pure softened water, reduce the water holding capacity, and improve the emulsion effect of asphalt or asphalt concrete.

In the asphalt-water system, the emulsifier molecules move between the asphalt and water interface, and the water-loving groups of the molecules are adsorbed on the surface of the asphalt, making it charged, while the hydrophilic groups enter the water phase. This connects the asphalt particles with water, reducing the interfacial tension between the two. At the same time, because the asphalt particles have the same charge and repel each other, they are prevented from agglomerating with each other, so that the asphalt emulsion can remain uniform and stable for a certain period of time. The nature of the charge is determined by the charge of the hydrophobic group or hydrocarbon chain of the emulsifier. If it is negatively charged, the asphalt particles are negatively charged, and the emulsion formed is an anionic asphalt emulsion. Otherwise, it is a cationic asphalt emulsion. If the asphalt particles have both negative and positive charges, the emulsion is a zwitterionic asphalt emulsion; in addition, there is also a non-ionic asphalt liquid.

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.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

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.

Emulsified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of emulsified asphalt equipment to fully demonstrate its performance; modified asphalt equipment is an asphalt binder made by adding rubber, resin, high molecular polymer, ground rubber powder or other fillers and other admixtures (modifiers), or taking measures such as mild oxidation of asphalt to improve the performance of asphalt or asphalt mixture; So how much do you know about the safe use and operation of modified asphalt equipment? Today, the editor will tell you;
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 the stability of the machine during work.
Regularly inspect whether the mixer blades are deformed and whether the screws are loose.
Inspect 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.
Before powering on, you should inspect and test run the empty vehicle, 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, you should stop the machine and check the asphalt tank.
Note: After the asphalt material is mixed, it is best to stop the machine for one hour, clean the drain material in the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing, and the blades are prone to rust. During use, everyone should pay attention to these small links to avoid unnecessary losses to their work.

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.

The slurry seal truck is mainly used for preventive maintenance of municipal pavement. It can improve the quality of the seal, effectively improve the integrity and crack resistance of the seal, extend the service life, and the construction process is simple without adding too many construction links. It is a kind of road maintenance equipment that has become quite popular in recent years.

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.

Recently, I found that many people don’t know much about the operation skills of asphalt pavement spreaders. If you also want to know what’s going on, you can read this introduction below.
Asphalt pavement spreaders are an indispensable and important equipment in road maintenance and construction. Their operation skills directly affect construction efficiency and project quality. The following introduces the operation skills of asphalt pavement spreaders from four aspects: pre-operation preparation, precautions during construction, spreading skills, and post-operation cleaning and maintenance:

During the road construction process, asphalt spreaders also play an irreplaceable role. Let’s take a look at the main performance advantages of asphalt spreaders produced by Sinoroader and where their main contributions exist?
1. Manual/automatic control of spraying volume and working width. Each nozzle can be controlled individually, and the determinant nozzles can be freely combined to adjust the spraying width at will. Spreading control can be performed in the cab or the rear platform.
2. The automatic control system can measure the vehicle speed and automatically calculate the number of revolutions of the asphalt pump according to the input spreading volume, spraying width and asphalt type, and then automatically adjust the number of asphalt pumps through the system.
3. The vehicle-mounted rapid heating system (10-15℃/h) can improve the heating efficiency and reduce the construction auxiliary time and spreading temperature;
4. The flushing nozzle system can blow out the remaining asphalt in the nozzle through diesel and high-pressure air to prevent the asphalt from freezing in the nozzle and increase the service life of the nozzle.

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.

The modified asphalt equipment estimates the quality and uniformity of various raw materials from the material pile and conveyor at any time. The modified asphalt equipment checks the soil and oversized gravel, and checks whether there is any leakage in the cold hopper. Estimate whether the mixed material is mixed evenly, whether there is white material, whether the oil-stone ratio is reasonable, and check the concrete segregation of the asphalt mixture and the mixed material.
The modified asphalt equipment checks the control parameters of various basic parameters of the mixing device in the control room, the display values ??of the control screen, and the modified asphalt equipment checks whether the data statistics and display values ??of the computer and printout are consistent. Test the raw material heating temperature and the mixed material entry temperature of the modified asphalt equipment.

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.
