What raw materials are good for asphalt cement?

Epoxy coal asphalt, commonly known as water asphalt, has excellent electrical insulation, water permeability resistance, microbial erosion resistance, stray current resistance, heat resistance, temperature difference resistance and other excellent properties, and the coating can be used between -4 150. It is mainly used for the anti-corrosion of the outer wall of buried or underwater oil, gas, water and thermal pipelines, and is also suitable for the anti-corrosion of various steel structures, docks, ships, sluices, gas storage tanks, oil refining and chemical plant equipment and the anti-leakage of sewage pools, roof waterproof layers and basement concrete layers. Asphalt cement is a polymer anti-corrosion and waterproof material, and there are mineral fillers and fiber substances in asphalt cement, which can prevent high-temperature flow and low-temperature cracking, and can be used for a long time.

As a new type of waterproof material, solvent-based asphalt cement has the advantages of wide application range, long life, weather resistance, deformation resistance, high tensile strength and large elongation. It solves the problems of traditional anti-corrosion and waterproof materials, such as the slide of the paint façade, the hollowing of the membrane, and the difficulty of operation of complex parts, and can completely replace the traditional anti-corrosion and waterproof materials, and has better anti-corrosion, waterproof and insulation properties. Asphalt cement is generally divided into high-build caulking type and thin-slurry coating type.

Asphalt cement is a prepared product, which can be used directly for construction, can be applied and scraped, and forms a complete layer of rubber high-elasticity colloidal elastomer after curing. It is a continuous closed system with no joints and no joints. After the anti-corrosion and waterproofing are completed, it can be used as a sand covering protective layer or other tracks.

The construction process of asphalt cement is as follows:

Concrete cushion and foundation: foundation cleaning first cold base oil second cold bottom oil intermediate acceptance asphalt cement coating acceptance.

The specific construction operation process is as follows:

1. Grassroots cleaning: Before operation, use wire brushes, brushes and oiler shovels to clean up the mortar lumps, cement powder and floating ash on the surface of the concrete.

2. After the grassroots cleaning is completed, apply the first cold base oil with a roller brush in time according to the divided construction sequence; The first cold base oil is dried, and then the second cold base oil is applied after the intermediate acceptance is carried out by the supervision unit.

3. After the cold bottom oil is dried, the asphalt cement coating is rolled in turn according to the divided construction sequence.

4. After the asphalt cement coating is completed, it will be reported to the supervision unit for acceptance, and the next process will be carried out after passing the qualification.

There are two ways to dilute asphalt: 1. Mixing, that is, mixing with thinner asphalt to dilute the asphalt to dilute the asphalt. 2. Mixed with diluent, diesel fuel is generally used; Gasoline is fine, but gasoline is easy to emit and flammable, so you should pay attention to safety when using it.

Xylene, which is added to the hot-melted asphalt cement, can be diluted, but the amount of xylene disturbed by the clump is very large. The asphalt is heated and diluted with diesel or engine oil. Solvents such as gasoline, kerosene, and diesel fuel can be used to dilute petroleum asphalt.

The use of condensant can make the asphalt cement set quickly.

Asphalt cement product overview: asphalt cement is a polymer anti-corrosion and waterproof material, this product is a permanent anti-corrosion and waterproof material, with long service life and convenient construction. The service life is more than 50 years.

Excellent characteristics of asphalt cement: It has a wide range of application, long life, weather resistance, deformation resistance, high tensile strength, large elongation, strong adaptability to base shrinkage and cracking deformation, acid resistance, alkali resistance, superior anti-corrosion and waterproof performance, and easy construction of any complex part, which solves the problem of traditional anti-corrosion and waterproof materials, such as paint façade slide, membrane hollowing, and complex part of difficult operation. It completely replaces the traditional anti-corrosion and waterproof materials.

It has better anti-corrosion, waterproof and insulating properties.

Asphalt cement application range: 1. Anti-corrosion and waterproof engineering of the bottom, side, back, foundation pit and basement of the concrete foundation of underground engineering projects; 2. Anti-corrosion and waterproof engineering of cement-based buildings, foundation pits, foundations, grounds, bridge piers, railways, ports, docks, coal mines, and oilfield drilling, 3. Anti-corrosion and waterproof engineering of troughs, water towers, pools, cooling towers, sewage pools, and edible clear water pools; 4.

Hello, you can consider the following methods: Add coagulant: Adding coagulant to asphalt cement can speed up its solidification process.

If the ambient temperature of the asphalt cement can be increased, its solidification process can be accelerated. Of course, solidification at too high a temperature can lead to undesirable effects, and the temperature needs to be controlled. Increase air circulation:

Oxygen is required for asphalt cement to solidify, so increasing air circulation can accelerate its solidification. Air circulation can be increased by opening doors and windows, using fans, etc. Accelerator:

Some special accelerators can speed up the solidification process of asphalt cement. For example, the use of urea-formaldehyde resins, phenolic resins, epoxy resins, etc. as accelerators can accelerate the solidification rate of asphalt cement.

What is the proportion of coagulant?

Pro, the amount of coagulant added is generally calculated as a percentage based on the weight of asphalt cement, and the cavity slag is generally between 1-5%. Excessive or insufficient coagulant addition may affect the performance and quality of asphalt cement. When using coagulants, be sure to follow the instructions or manufacturer's recommendations for the correct amount and proportion.

Dear, I'm glad to answer your <>

A: Asphalt cement does not stick to water and organic solvents. Asphalt cement is a black-brown complex mixed mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives, which is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum, and the surface is finger rotten black, soluble in carbon disulfide and carbon tetrachloride.

Asphalt loser is a waterproof, moisture-proof and anti-corrosion organic cementitious material. Asphalt can be divided into three main types: coal coke asphalt, petroleum asphalt and natural asphalt: among them, coal coke asphalt is a by-product of coking.

Petroleum bitumen is the residue after distillation. Natural bitumen is stored underground, and some form layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries, as well as paving roads.
