What should I pay attention to when using different types of bitumen melting equipment?

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?

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.

I believe that after a long period of contact with asphalt tanks, everyone knows that the working efficiency of emulsified asphalt equipment actually depends on the operator. The more experienced the operator is and the stronger his ability to deal with various emergencies is, the higher the working efficiency will be, and the safety will be guaranteed. Mastering more equipment-related knowledge is what every friend should pursue. Today, the editor will explain to you the details that need to be paid attention to when operating emulsified asphalt equipment:

Energy conservation and environmental protection are also excellent ways for Chinese companies to break down foreign trade barriers. By the end of 2011, the annual fuel consumption of my country’s construction machinery products exceeded the total annual output value of construction machinery. Currently, market entry barriers in countries like the United States and Japan are rising, and emission standards are a primary concern among these trade barriers. Industry experts believe that energy conservation and emission reduction in the construction machinery industry are challenging, often hindered by technical bottlenecks. Therefore, increasing research and development efforts is an effective way to address this situation. Energy conservation and environmental protection are the inevitable trends in the development of China’s construction machinery industry.
Whether it is to reduce environmental burdens or break down foreign trade barriers, energy conservation and environmental protection will become the mainstream trend in the development of construction machinery. The future development of China’s construction machinery industry will place greater emphasis on transformation and upgrading, and energy conservation and environmental protection will be a key focus in its implementation strategies. Currently, construction machinery manufacturers are incorporating more energy-saving and environmental protection elements into their new products. At the just-concluded biennial Shanghai Bauma Show, renowned international construction machinery companies like Komatsu, Hyundai, and Volvo Construction Equipment, as well as Chinese construction machinery giants like Sany, XCMG, Zoomlion, and Liugong, showcased their latest equipment, all boasting enhanced energy-saving and environmental performance. This demonstrates that the future of construction machinery will inevitably be dominated by energy conservation and environmental protection. Construction machinery companies must prioritize their own efforts to achieve higher product efficiency and superior energy-saving and consumption-reduction performance.

The slurry sealer is a special equipment for road maintenance that we see in our lives. The slurry sealer is mainly used to deal with the decrease in surface wear resistance, cracks, etc. of the road, to improve the waterproofness and skid resistance of the road surface, thereby greatly improving the driving comfort and flatness inside, so as to achieve a new effect for the road surface. So what is the operation process of the slurry sealer?
Before starting the slurry sealer, you should be prepared to test the quality of the slurry sealer materials before construction. One of the most important points is to certify and inspect whether the content of emulsified asphalt can meet the requirements of the specification, and the mixture should also meet the requirements. After confirming the measurement standards, check that the road surface to be constructed should be dry, free of debris, water, flat, etc.

Asphalt distributors can spray, lay, and compact asphalt, improving construction efficiency and ensuring project quality.
Asphalt distributors play a crucial role in modern road construction. They not only efficiently apply asphalt but also assist with laying and compacting, providing strong technical support for road construction. So, how do asphalt distributors accomplish these three key tasks? Let’s take a closer look.
1. Asphalt Spraying: Uniform and Efficient, Improving Project Quality
One of the primary functions of an asphalt distributor is to spray asphalt. It evenly applies asphalt to the road surface, ensuring the thickness and uniformity of the asphalt layer meet design requirements. During the spraying process, the asphalt distributor can adjust the spraying speed and volume according to actual needs to meet varying road conditions and construction requirements. Furthermore, asphalt distributors are equipped with advanced control systems that precisely control the amount of asphalt sprayed, avoiding waste and pollution.
2. Asphalt Paving: Smooth and Dense Paving, Improving Road Performance
After spraying asphalt, asphalt distributors can also perform asphalt paving. It quickly spreads the asphalt sprayed on the road surface and, through vibration or rolling, makes the asphalt layer denser and smoother. This step is crucial for improving the road’s smoothness, density, and skid resistance. The asphalt spreader’s laying process ensures that the asphalt layer is tightly bonded to the base layer, forming a complete pavement structure.

According to statistics, among the high-grade highways that have been built and opened to traffic in my country, about 80% are asphalt pavements. However, with the development of time, the influence of various climatic and environmental factors, and the high-intensity driving load, the asphalt pavement will have different degrees of degradation or damage. Pavement maintenance is to take effective technical means to slow down this degradation, so that the pavement can provide good service quality during its service life.

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.

The viscosity of the bitimen melter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitimen melter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitimen melter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitimen melter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the asphalt debarrel equipment from weaning when the moisture of th

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.
The micro-surface slurry seal requires emulsified asphalt and stone that meet the standards. The metering system of the micro-surfacing paver needs to be calibrated before construction. The production of emulsified asphalt requires asphalt heating tanks, emulsified asphalt production equipment (capable of producing asphalt content greater than or equal to 60%), and emulsified asphalt finished product tanks. In terms of stone, mineral screening machines, loaders, forklifts, etc. are needed to screen out oversized stones.
The tests required include emulsification test, screening test, mixing test and the equipment and technical personnel required to do these tests.

Some of the equipment of emulsified modified bitumen equipment are as follows. The specially made bitumen filter can effectively filter the residues and dirt in the high-temperature culture medium bitumen to avoid damage to the subsequent equipment. The emulsified modified bitumen equipment adopts a spiral plate type or a shell and tube heat exchanger to quickly heat the culture medium bitumen through high-temperature heat transfer oil to meet the needs of the production process. The emulsified modified bitumen equipment is heated in the storage tank to prevent the bitumen from aging due to long-term high-temperature heating and exposure to the air. The sulfate generated during the production process of the emulsified modified bitumen equipment is very limited, reducing air pollution.
The emulsified modified bitumen equipment sends the modified material manually poured into the dumping bin to the bitumen batching tank by wind or spiral. It can be equipped with a metering and calibration system. The emulsified modified bitumen equipment thickener is automatically or manually added. The emulsified modified bitumen equipment can be equipped with a metering and calibration system. Emulsified modified bitumen equipment transportation and metering and calibration system, the emulsified modified bitumen equipment adds the set bitumen amount to the batching tank through the frequency converter and computer interlock. The emulsified modified bitumen equipment and bitumen steam flowmeter use big brand products to ensure the preparation.

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:
(1) Minor repair and maintenance project: preventive maintenance and repair of slightly damaged parts of the highway and all its engineering facilities to keep them in good condition. It is usually planned and carried out daily by the maintenance team within the annual minor repair and maintenance quota funds on a monthly (ten-day) basis.
(2) Medium repair project: regular repair and reinforcement of general wear and tear and local damage of highway engineering facilities to restore them to their original state. It is usually planned and implemented by grassroots road maintenance agencies on an annual (seasonal) basis.
(3) Major repair project: periodic comprehensive repair of major damage to highway facilities to fully restore them to the original design standards, or local improvements and individual additions within the original technical level to gradually improve the highway’s traffic capacity. It is usually organized and implemented by grassroots road maintenance agencies or with the help of their superior agencies according to the approved annual project budget.
(4) Improvement projects are large projects that improve the technical level of roads and their engineering facilities in stages and sections due to their inability to meet traffic volume and load requirements, or significantly improve traffic capacity through improvements. It is usually organized and implemented or completed through bidding by regional road maintenance agencies or provincial road maintenance agencies according to the approved plan and design budget. As a manufacturer of asphalt spreaders, we welcome you to visit us.

To ensure good operation of asphalt melting equipment and extend its service life, regular maintenance and repairs are required. The following are specific maintenance and repair steps:
First, various parts of the equipment, including heating elements, pipes, valves, etc., need to be inspected regularly to make sure they are not worn or damaged. If any problems are found, they should be repaired or replaced immediately.

1 Common diseases of asphalt pavement
There are nine phenomena of early damage to asphalt pavement: rutting, cracks, and potholes. These diseases are the most common and serious, and are one of the common quality problems of highway projects.
1.1 Rutting
Rutting refers to the longitudinal strip grooves on the road surface along the wheel tracks, with a depth of more than 1.5cm. Rutting is a strip groove formed by the accumulation of permanent deformation of the road surface under the repeated action of vehicle load. Rutting reduces the smoothness of the road surface. When the rutting reaches a certain depth, due to the accumulation of water in the rutting, it is easy for cars to slide and cause traffic accidents. The main reasons for rutting are unreasonable design and serious overloading of vehicles.
1.2 Cracks
There are three main forms of cracks: longitudinal cracks, transverse cracks and mesh cracks. When cracks occur in asphalt pavement, water seepage occurs, which harms the surface layer and base layer.
1.3 Potholes
Potholes are common early diseases of asphalt pavement, which refer to the road surface being damaged into potholes with a depth of more than 2cm and an area of ??more than 0.04㎡. The main reason for the formation of potholes is that the oil used in vehicle repair or motor vehicles seeps into the road surface, polluting the asphalt mixture and causing it to loosen. The pits are gradually formed by driving and rolling.

After the emulsified bitumen equipment has been used for a long time, it needs maintenance. There are several points to note when adjusting the emulsified bitumen 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 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 inspection and reinstallation, the coaxiality error between the housing and the main shaft must be corrected with a dial indicator ≤0.05mm;
5. When repairing the machine, it is not allowed to be directly knocked with an iron bell during the disassembly, reinstallation and adjustment process. Use a wooden hammer or a wooden block to knock gently to avoid damaging the parts;
6. The machine seals: 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 casting immediately. The grinding material should be ≥200# silicon carbide grinding paste. If the seal is damaged or cracked seriously, please replace it immediately.

In the application, the asphalt spreader has intelligent asphalt spreading rate and low investment, low power consumption, low cost, high thermal efficiency. The asphalt spreader can reach the temperature required for construction in a short time. It is easy to use and move. It can be operated by one person. A set of electric heaters is a bit expensive. In the production process of the asphalt spreader, water, as a production material, needs to be heated from room temperature to about 55°C. The evaporation heat of the asphalt spreader is transferred to the drainage. It is found that after the emulsified asphalt is produced for 5 tons, the asphalt spreader is accompanied by a significant increase in the temperature of the cooling circulating water. The production water uses cooling circulating water, and the water basically does not need to be heated. It can save 1/2 of the fuel simply from the energy.
