How to choose auxiliary materials suitable for emulsion bitumen equipment

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

When using asphalt melting equipment, you need to pay attention to the following points:
1. The power must be cut off during installation and operation to ensure safety.
2. Before starting operation, check whether all components are normal and have no fault prompts. In particular, the inspection of key parts such as the heater part and the conveyor belt device is particularly important.

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.

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.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

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.

The emulsified bitumen equipment hot-melts the base cold-mix colored bitumen, and then disperses the slightly cold-mixed colored bitumen particles into the aqueous solution containing emulsifier through a machine to form liquid cold-mixed colored bitumen sheets.

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?

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.

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.

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.

If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

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.

Stainless steel bitumen melters use bitumen concrete micro-powder machines. Its blade strength is high, the angular velocity of the moving disc is high, and the gap can be adjusted to 0.15mm. Stainless steel bitumen melters are suitable for the production and processing of various polymer bitumen concrete, such as SBS, PE, EVA, etc.
Stainless steel bitumen melters use independently developed special batching tanks, stainless steel bitumen melter force stirring devices, liquid level meter overflow prevention equipment, granular material dosage and equipment, liquid additive automatic addition equipment and other production key points. It ensures the full-position process guarantee for the stainless steel bitumen melter of the bitumen concrete production line. The stainless steel bitumen melter processing stainless steel bitumen melter rate is significantly increased, and the quality of stainless steel bitumen melters is greatly improved.

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

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.
