How to apply for the business license of block asphalt melting equipment?

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.

Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

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.

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:

Each F1 track must be paved with three layers of asphalt, middle and lower, of which the lowest layer is 10 cm coarse asphalt concrete bearing layer, its flatness is less than 8 mm; In the middle is a 4 cm medium grained asphalt concrete bond layer, its flatness is less than 5 mm; The top layer uses 4 cm modified asphalt mixture as the surface wear layer, and the flatness is less than 2 mm.

The paved F1 track cannot have more than 3 points per kilometer of flatness detection, which is much higher than the highway.

The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) Open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

1. When operating an asphalt spreading truck, first check whether the machinery, spreading devices, protective and fire prevention equipment are complete and effective.
2. It is strictly prohibited to use non-specified fuel as the fuel for the heating system. The fuel is not allowed to overflow outside the tank. Generally, the oil level should be 20-30cm lower than the upper end of the overflow pipe.

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.
The special bonding material for fine surfaces produced by Sinoroader Group has the characteristics of good bonding performance and good durability. The specific construction process is roughly as follows:

The bitumen decanter equipment is mainly composed of barrel removal shell (BOX), hoisting mechanism, hydraulic booster and electrical control system. The shell is divided into two chambers, the left and right chambers. The upper chamber is a chamber for melting a large barrel of bitumen (definition: the transformation process of a substance from solid to liquid). There are heating coils evenly distributed around it.

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.

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

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.

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.

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.

Whether it is the application of modified asphalt equipment or the application of other equipment, if you want to extend its service life, you need to do daily maintenance work. In order to better help everyone, we have modified asphalt The maintenance methods that can be adopted when using the equipment are introduced as follows:

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.

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.

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.

There are many ways to heat bitumen, including using fire source heating, electric heating, steam heating, hot water heating and indirect heating. Fire source heating generates heat by burning fuel to heat the bitumen to a molten state. Electric heating converts electrical energy into thermal energy through electric heating elements to heat the bitumen to a molten state. Steam heating transfers heat to bitumen through steam, heating the bitumen to a molten state. Hot water heating transfers heat to the bitumen through hot water, heating the bitumen to a molten state. Indirect heating transfers heat to the heating medium, which then transfers the heat to the bitumen to heat the bitumen to a molten state.

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.

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.

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.

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.

The slurry seal truck is one of the main maintenance methods of highways. The slurry seal is made of emulsified asphalt as the binding material, well-graded mineral materials, fillers, water and additives, etc., mixed in a certain proportion. The slurry mixture is evenly spread on the old road surface to be treated with a sealing truck, and is firmly combined with the original road surface to form a new thin layer of asphalt mixture. So what preparations need to be done before construction? Let’s find out below.

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.
