Detailed explanation of the composition of emulsified asphalt equipment, there is always something you don’t know

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.

Contemporary roads and pavements have undergone many changes: traffic volume and driving frequency have increased significantly, the axle load of logistics trucks has continued to increase, one-way driving in separate lanes has been widely implemented, and regulations have further improved the anti-flow resistance of the ground, that is, the work of modified asphalt equipment under high temperatures ability;

Asphalt emulsifiers can be divided into synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. according to their formation. Synthetic emulsifiers are currently the most widely used. Asphalt emulsifiers are a type of organically synthesized surfactant that can emulsify asphalt.
Emulsifiers are divided into ionic and non-ionic types according to whether the hydrophilic group of the emulsifier molecule is charged when the emulsifier is dissolved in water. Ionic emulsifiers are divided into cationic and anionic types due to the different charges of the hydrophilic group after ionization in water. In addition, there are zwitterionic types.
Cationic emulsifiers are divided into three types: fast cracking, medium cracking, and slow cracking according to the speed of demulsification. Slow cracking emulsifiers are divided into slow setting and fast setting according to the length of time the mixture solidifies. Slow cracking and slow setting types are mainly used as permeable oils. Slow cracking and fast setting are used for micro-surfacing, slurry sealing, cold regeneration, etc. Medium cracking and fast cracking types are used for adhesive layer oils, gravel sealing layers, and waterproof base oils.

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

Microsurfacing is a thin layer of overlay placed on old asphalt pavement and is a type of preventive maintenance process. The purpose of microsurfacing is road maintenance. After micro-surface paving, it can repair cracks in the original road surface, waterproof and beautify the road surface.
The construction method of micro surfacing is: using a micro surfacing paver to evenly spread modified emulsified asphalt, a certain grade of mineral materials, water and other additives on the road surface in a certain proportion.

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.

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.

● Reliable performance, durability and easy operation;

The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the key requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage such as slurry, looseness, and potholes to the asphalt pavement. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.
So let’s take a look at how the construction of the asphalt gravel synchronous sealing truck is carried out:

I believe that many people already know about synchronous gravel sealing. But when asked under what circumstances synchronous gravel sealing is suitable, many people cannot tell.
Under what circumstances is synchronous gravel sealing more suitable? According to the technical specifications for the construction of simultaneous gravel sealing, simultaneous gravel sealing can be used for the following disease types:

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.

Technical features of fiber sealing equipment:
1. Zero starting strong injection technology
With more than ten years of manufacturing history of asphalt spreading trucks and asphalt gravel synchronous sealing trucks, the zero-start strong spraying technology has been accumulated for many years. The combination of time-reliable hydraulic transmission components and Meitong’s control system can make the equipment instantly start from zero. Spraying starts in line, stable and reliable.
2. Duplex sealing structure
The sealing process of this equipment is a three-layer simultaneous and continuous construction process of one layer of asphalt + one layer of fiber + one layer of asphalt, forming a layer of interactive dense network winding structure, which fully meets the user’s construction requirements.

I believe everyone is familiar with the relevant knowledge about modified bitumen equipment. As users continue to increase its application, we have also talked about it a lot in the above articles and learned that it is mainly engaged in the production of modified bitumen. Production, in order to further enhance users’ understanding of it, professionals summarize its relevant characteristics as follows:

Synchronous sealing trucks play an important role in road maintenance. Daily maintenance of synchronous sealing trucks is an important part of ensuring the good operation of the equipment and extending its service life. Here are some common maintenance measures:

No matter what product is used, after using it for a period of time, some large and small problems will inevitably arise, which will affect our work, just like the use of asphalt heating equipment will cause problems such as uneven asphalt pavement. We know that for the use of asphalt heating equipment, the construction of asphalt pavement is affected by many factors, including the quality of construction personnel, the quality of roadbed construction, the treatment of the two sections of the bridgehead culvert and the expansion joint of the bridge, the construction of the road subbase and base, the selection of road construction machinery and the quality of road materials. These are the main reasons affecting the flatness of the road surface.
In order to better help customers apply it, professionals introduce the use of asphalt heating equipment. Flatness is an important indicator for measuring the quality of high-grade pavement. Unsmooth pavement will increase driving resistance and cause additional vibrations in the vehicle, which will directly affect the safety and comfort of driving. At the same time, it will aggravate the damage of automobile parts and tires and increase fuel consumption.

As a black road construction machinery, the synchronous chip sealer is the main equipment for highways, urban roads, airports, and port terminal facilities. Do you know what kind of synchronous chip sealer? What products do you have to choose from?
Asphalt dispensers are classified according to the purpose, operation mode, and drive mode of the asphalt pump. According to the purpose, asphalt dispensers can be divided into two types: road use and road construction use. The asphalt tank capacity of the asphalt dispenser used for road construction generally does not exceed 400L, while the asphalt tank capacity of the asphalt dispenser used for road construction is 3000-20000L.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports. This equipment is mainly used to spray different types of asphalt on the ground to meet the construction requirements of different levels of ground oil permeable layer, sticky layer, left and right permeable layer, fog permeable layer, etc.

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.

Asphalt mixture is a kind of composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, some also added polymer and wood cellulose; By these different quality and quantity of materials mixed to form different structures, and have different mechanical properties

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.

Road repair Keep the road to maintain the performance of the road, restore the damaged part in time, ensure the safety, comfort and smooth driving, save transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time. With the performance, the damaged part is restored in time to ensure the safety, comfort and smooth driving, saving transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time.

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.

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 equipments can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.
First of all, reliable asphalt melter equipment can shorten heating time and work efficiency and avoid wasting energy. Secondly, the equipment is easy to operate and can reduce the incidence of on-site safety accidents. In addition, this equipment has an automatic control and monitoring system that can adjust the working status and parameters at any time to meet different construction needs and environmental conditions.

After the emulsified asphalt equipment has been used for a long time, it needs maintenance. There are several points to note when adjusting the emulsified asphalt equipment:
1. During use, regular maintenance should be carried out as appropriate according to the processing materials;
2. For the maintenance and use of the motor, please refer to the motor instruction manual;
3. Most of the random spare parts are national standard and department standard parts, which are purchased all over the country;
4. The colloid mill is a high-precision machine with a line speed of up to 20m/second and a very small grinding disc gap. After overhaul, the coaxiality error between the housing and the main shaft must be corrected with a dial indicator to ≤0.05mm;
5. When repairing the machine, it is not allowed to be directly knocked with an iron bell during the disassembly, reassembly and adjustment process. Use a wooden hammer or a wooden block to knock gently to avoid damaging the parts;
6. The seals of this machine are divided into static and dynamic seals. The static seal uses an O-type rubber ring and the dynamic seal uses a hard mechanical combined seal. If the hard sealing surface is scratched, it should be repaired by grinding on flat glass or flat castings immediately. The grinding material should be ≥200# silicon carbide grinding paste. If the seal is damaged or cracked seriously, please replace it immediately.

Asphalt emulsifier is an emulsifier that belongs to the category of surfactants and is a raw material for the production of emulsified asphalt.
Emulsifiers are divided into: synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. Currently, synthetic emulsifiers are widely used. Asphalt emulsifier is a type of chemical organically synthesized surfactant.

Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.

How to reduce energy consumption of emulsified asphalt machinery is a concern of many users and many manufacturers. Therefore, today, Sinosun Company, as a manufacturer of emulsified asphalt equipment, would like to take this opportunity to share with you the method of reducing energy consumption of emulsified asphalt machinery.
Since emulsified asphalt appears as a finished product in emulsified asphalt machinery, and the outlet temperature of ordinary emulsified asphalt is about 85℃, and the outlet temperature of emulsified modified asphalt is above 95℃, there is a lot of latent heat in emulsified asphalt, but the emulsified asphalt equipment does not make good use of them, but directly enters the finished product tank, allowing heat to be lost at will, resulting in energy waste.

The advantages of Sinoroader bitumen decanter equipment over similar domestic equipment are reflected in the following points:
1. The equipment produces 8-10t/hour, with an automatic telescopic sealed container structure. It uses an electric hoist to lift the asphalt barrel at the inlet guide tube.
