Bitumen melting equipment has the following characteristics and advantages

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?

1. Observation: Pay attention to the dynamics of the road surface after milling (three to four days), and pave the milled and roughened road surface in time when paving conditions are met.
2. On-site mixing: During construction and production, a sealing slurry truck should be used for on-site mixing. Through the metering equipment of the sealing truck and on-site operation by a robot, it is ensured that emulsified asphalt, water, mineral materials, fillers, etc. can be mixed according to a certain proportion. , stir through the mixing box, and the paving thickness is not higher than the roughing depth.

As we all know, emulsified bitumen is a single-component black viscous liquid that can combine the roadbed and the pavement to improve the performance and service life of the road. So what problems should be paid attention to when using emulsified bitumen? Let’s follow the editor of Sinoroader Group, an emulsified bitumen manufacturer, to learn about it.

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.

Synchronous gravel sealing technology refers to the use of special synchronous gravel sealing truck equipment to lay and roll prepared gravel, asphalt and other materials to build a single layer of asphalt gravel wearing layer, which is important for highway pavement. protection of.

Fillers used in emulsion bitumen equipment are generally divided into two types: chemically active and non-chemically active. In the production of emulsion bitumen equipment, it can improve the stability of the slurry mixture, speed up or slow down the demulsification speed, and improve the strength of the sealing layer. When adding chemically active fillers, the reaction and compatibility of the fillers with mineral materials and modified emulsion bitumen should be fully considered.

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.

In the cold winter, you need to pay attention to the following points when using asphalt melting equipment:
1. Protection from cold and warmth: The equipment needs to be operated indoors or in a place with shading facilities, and ensure that the temperature of the equipment and the surrounding environment is maintained within an appropriate range.
2. Check the equipment: Before use, the equipment should be checked, including whether the circuits, fluid circuits and other parts of the equipment are working normally, and whether there are any leaks of electricity or water in the equipment.
3. Pay attention to safety: During operation, you should wear protective equipment and avoid direct contact with hot asphalt. At the same time, it is necessary to avoid equipment overload operation and prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the equipment according to weather conditions and road conditions to avoid overheating of the equipment, causing asphalt to flow too quickly or burn.
5. Storage conditions: When not in use, place the device in a dry, ventilated place with moderate temperature, and ensure that any residue in the device is completely removed.

What is the overall operation process of bitumen (composition: asphaltene and resin) drum melting equipment?
The bitumen (composition: asphaltene and resin) drum melting equipment produced by our company mainly uses barrel debarking and melting of large barrels of bitumen (definition: the transformation process of materials from solid to liquid), using high-temperature thermal oil as the material (playing a decision-making role substance), used in supporting facilities of high-temperature thermal oil heating equipment. Bitumen drum melter equipment has the functions of barrel delivery, barrel removal, storage, temperature raising, slag discharge, etc. It is an essential product for high-grade highway construction companies. Bitumen drum melter equipment can be used for resin barrel removal. The bitumen drum melter equipment mainly consists of barrel removal shell, hoisting mechanism, hydraulic booster and electrical control system.

Asphalt sealant is a material specially used for road crack repair. The following is a detailed introduction to asphalt sealant:
1. Definition and composition
Asphalt sealant is a road repair material made of asphalt or modified asphalt as the base material, with a certain amount of additives and fillers added, and processed by special technology. It usually has a black or dark brown appearance and is in a solid or semi-solid form.
2. Main characteristics
High adhesion: Asphalt sealant can firmly bond to the crack wall of the road surface to form a tight sealing layer to prevent moisture and other harmful substances from invading the road surface structure.
High elasticity: It has a certain elastic recovery ability and can adapt to the expansion and contraction changes of the road surface to prevent further expansion of cracks.
Weather resistance: After special process treatment, it has good weather resistance and can maintain its stable performance for a long time.
Convenient construction: The construction operation is simple and fast, without complex construction machinery, which reduces the construction cost.
3. Scope of application
Asphalt sealant is widely used in crack repair of various asphalt pavements, including highways, urban roads, airport runways, etc. At the same time, it can also be used for the maintenance and repair of asphalt surfaces such as bridges, tunnels, and parking lots.

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.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

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.

Is the performance of Sinoroader’s fully automatic emulsified asphalt production equipment stable and unstable? To be honest, whether the performance of a product is stable or not can only be known through practice, right?
Chairman Mao, the great leader of China, once said, “Without practice, there is no right to speak.” Yes, people who have never used it naturally have no right to speak. Now the editor will talk about the fully automatic emulsified asphalt production equipment that I am using!

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:

Emulsified modified asphalt equipment is classified according to the production process and can be divided into three types: intermittent emulsified modified asphalt equipment, semi-continuous emulsified modified asphalt equipment, and continuous emulsified modified asphalt equipment. During the production of emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are blended in a soap mixing tank, and then pumped into the asphalt into the colloid mill. After a can of soap is used up, the soap is redispensed, and then the production of the next can is completed.
The emulsified modified asphalt equipment mentioned here includes hot water pumps and circulation pumps. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Pay attention to the sewage outlet at the bottom of the emulsified modified asphalt equipment pump. The water in the water tank is released through the filter valve. Some emulsified modified asphalt equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange bolts at the bottom. There are basically two methods of moisturizing emulsion pumps for emulsified modified asphalt equipment on the market, gear oil pumps or centrifugal water pumps. The gear oil pump can only drain the liquid in the pump through the connecting flange of the pipeline. The centrifugal water pump carries out sewage treatment through its own sewage outlet.
When used in the production of emulsified modified asphalt equipment, depending on the modified material technology, the latex pipeline can be connected in front of the colloid mill or behind the colloid mill, or there may be no latex pipeline and it must be made manually. Add the required amount of latex into the soap jar.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

Synchronized gravel sealing is a process technology for treating cracks in asphalt pavement, and it is currently a road construction and pavement maintenance technology with low energy consumption and high cost performance. Do you know what its six technical features are? If you don’t know, just follow the editor of Sinoroader and take a look.

Preventive pavement maintenance is a periodic mandatory maintenance measure, which is taken to restore the pavement surface service function when the pavement structure strength is sufficient and only the surface function is attenuated. New preventive maintenance technologies such as super-viscous fiber-added low-noise micro-surfacing and synchronous gravel seal have been widely used on the main lines of national highways, and the construction effect has been widely praised by customers.
Super-viscous fiber-added low-noise micro-surfacing starts with the gradation of micro-surfacing and the main material modified emulsified asphalt. By reducing the structural depth of the micro-surfacing and changing the distribution state of the coarse and fine materials on the surface of the micro-surfacing, the driving noise is reduced, while ensuring its anti-skid performance, effectively improving its adhesion, waterproofness, durability and crack resistance, and can solve the defects of easy detachment, excessive noise and reflective cracks of ordinary micro-surfacing.

Friends who are ready to get started have a surprise today. The editor will give you a brief introduction on how to produce emulsified asphalt.
