Compared to most people, epoxy coal bituminous coatings do not know, epoxy coal asphalt coating is a coating that has protection, decoration, and other functions. For modern coatings, marking, anti-fouling, insulation and the former two functions are more and more showing their importance. With the development of the national economy and the advancement of science and technology, coatings will provide and exert various updated special features in more ways. Here we come to understand what is the next epoxy asphalt coating and epoxy coal tar coating construction process. What is epoxy asphalt coating Epoxy coal asphalt coating, main components, two-component self-drying coating: Part B paint: composed of epoxy resin, coal tar pitch, pigments, additives and diluents, etc.; the other component: special epoxy curing Agent. The paint film has excellent adhesion, impact resistance and water resistance. Excellent drying performance. High rust resistance, good chemical resistance and oil resistance, good wear resistance. Using high-pressure airless spray, easy to form a thick film coating. Widely used in the bottom of the ship, ballast water tanks, pier steel piles, iron and steel stents, acid tanks, water pipes, and cooling water pipes of industrial and mining enterprises, the outer wall anti-corrosion primer, topcoat. Epoxy coal tar coating (solvent type) is mainly used for anti-corrosion of Steel Pipe outer wall, steel components and cement components buried in the ground and in contact with the ground. As an anti-corrosion and heavy anti-corrosion coating, it has the following performance requirements: High film thickness: epoxy coal pitch Paint, usually with a coating thickness of 300 μm or more, must be of a thick paste type or a non-solvent type. Ordinary epoxy coal tar coatings are not suitable for heavy anti-corrosion coating, increasing construction costs and coating cycles. Construction performance: In heavy anti-corrosion coating, it is required that the epoxy coal tar coating can adopt airless spray or brush roller coating with a higher film thickness and no sagging. Appropriate weather resistance: After the epoxy coal tar coating is applied, the pipeline is usually stored in open air. The proper weather resistance can ensure that the open storage will not reduce the anti-corrosion performance of the coating. Basic anti-corrosion properties: It has anti-microbial, good electrical insulation properties, resistance to soil, sewage, moisture, hot and humid, alternating hot and cold environments. Epoxy coal asphalt paint performance and use: 1. The epoxy coal tar lacquer coating is a two-component coating. When used, firstly, stir and mix thoroughly, then mix according to the proportion and stir evenly. After curing for half an hour, it can be used. It needs to be used within 8 hours. 2. The surface of the metal must be rusted and decontaminated to a different extent. Its life span is more than twice as long. 3. The product is an aromatic hydrocarbon solvent, which is in good agreement with the same type of solvent coating. 4. The concrete substrate is required to be dry and its appearance is whitish. And wash the white precipitate and then apply a primer. 5. The surface of cement and concrete is generally rough, so primers are required to be diluted so that they penetrate into the pores to form nails and enhance adhesion. 6. Epoxy coal asphalt paint coatings can be reinforced with glass cloth to extend the service life. 7. The thickness of each layer of the primer is ≥25um, the dosage per square meter is about 250g, the thickness of each layer of the topcoat is ≥60um, and the dosage per square meter is about 500g. 8. The primer plus thinner material does not exceed 10%, and the topcoat plus thinner material does not exceed 5%. Epoxy coal asphalt coating construction process Light anti-corrosion ----- film thickness is about 0.2-0.5mm. It can be used for underground thermal insulation pipe, trench pipe, large tank inner and outer wall, chemical equipment, gas tank, reservoir power station, sewage tank and so on. One layer of primer (epoxy zinc-rich primer or epoxy iron-red primer or epoxy coal-tar asphalt primer) is used in an amount of 0.3 kg per layer of two-layer paint (epoxy coal-tar pitch anti-corrosion paint) per square meter 0.4-0.9kg. Ordinary anti-corrosion ----- film thickness is about 0.4-0.5mm, can be used for direct underground pipelines and buried equipment inside and outside walls. A layer of primer (thick paste type epoxy coal tar anticorrosion paint primer), 0.3kg per layer of glass fiber cloth, 1.1 square meters per square amount of three-layer paint (high-strength epoxy asphalt corrosion protection Paint finish), the amount per square is 0.7-0.9kg. Reinforced grade anti-corrosion ------ Film thickness is about 0.6-0.8mm, used to cross high salt, alkali, marsh or other harsh environments. One layer of primer (thick paste type epoxy coal tar anticorrosion paint primer), 0.3kg per square gram of double glass fiber cloth, 2.2 square meters of four-layer paint per square meter (thick paste type epoxy coal tar antisepsis Paint finish), 0.9-1.50kg per square Specially-enhanced grade -------- The film thickness is about 1.6-2mm, which is used for the underground steel components crossing the road building. One layer of primer (thick paste type epoxy coal asphalt anti-corrosion paint primer), the amount per square is 0.3kg seven glass fiber cloth, the amount per square is 7.7 square meters nine layer paint (thick paste type epoxy coal pitch antisepsis Paint finish), the amount of 1.8-2.0kg2 per square Epoxy coal asphalt paint coating Note: 1. Primer and topcoat are two-component packaging components. Before coating, they are prepared in proportion, mixed uniformly, and matured for half an hour before they can be coated. 2. The coating coating interval should be painted after the film surface is dry. The coating system for coating the glass cloth should be coated with a glass cloth at the same time to make the glass cloth saturated with the paint. Material, to ensure the quality of the coating layer. 3. Before the primer is applied, the surface of the metal shall be sandblasted and degreasing, and the oil shall be treated to meet the standard Sa2.5. 2.4 After the paint is fully cured (usually seven days), it can be buried and used.
