Coal tar epoxy pipe technology to improve the traditional coal tar epoxy anti-corrosion steel is the traditional manual winding glass cloth, efficiency slow process rough. Many customers do not reflect the coating surface neat, bubbles, uneven thickness. After site visits and case analysis of plant scientists I finally found a novel solution to solve the customer's concern! Pipe the past are not moving, and now we make steel spin up, this is not difficult, on our homemade electric stand, turn on the power, toggle gear (speed controllable), workers armed with glass cloth and machine, so out of coal tar epoxy anti-corrosion steel pipe, whether it is an oil-cloth two, or three-step three oil cloth five oil are very smooth! Coal tar epoxy anti-corrosion steel pipe, spiral steel outer coating of coal tar epoxy anti-corrosion steel pipe, spiral pipe external corrosion is a common form of corrosion. It's using a wide range of small to large diameter spiral pipe 32 3020 can choose this type of corrosion. Works on the market the most common external corrosion spiral steel pipe mostly because those who use coal tar epoxy anticorrosive this general level, pressure and the nature of the corresponding media is not very high, so the use of spiral steel pipe. A Product Description: Epoxy + + paint filler made of coal tar pitch on the steel surface is coated with a glass cloth made as to strengthen the anti-corrosion layer thickness 0.5 ~ 1.0mm. Various high-temperature areas along the coast, salt; the leakage can be widely used in underwater corrosion of steel and cement components customized according to customer cloth Second Third Fourth cloth two oil to the oil paint, underground gas pipelines and in the lower part of the sink cabinet protection mechanical corrosion; chemicals and other pipeline corrosion inside and outside walls. Implementation of the standards: "SY / T0447-96" two Category: 1. Press pipe shape classification can be divided according to the shape: round pipe, square tube, rectangular tube, octagonal, hexagonal, D-shaped, pentagonal shaped steel tubing, etc., complex section steel, double concave steel pipe, five plum-shaped steel conical pipe, corrugated steel pipe, oval-shaped steel, double convex steel pipe. 2. By Application steel use can be divided into: steel pipes, thermal equipment with steel pipes, industrial machinery drilling with steel, petroleum, geology steel, container steel, chemical industry with steel pipes, steel and other special purposes. Three: external corrosion pretreatment quality steel front pipe surface coal tar epoxy coated steel depends largely on the degree of adhesion of the coating and the pipe surface adhesion in turn depends on the quality of the tube surface rust , rust quality including cleanliness and surface roughness, surface rust good pipe and coating ensures great adhesion layer to prevent corrosion during transportation, storage, under the ditch and backfill process, due to the collision, friction with soil pressure drop caused cracking and falling, to ensure the integrity of the coating and sealing, effectively prevent the intrusion of corrosive media. Coal tar epoxy paint brush (1): coal tar epoxy paint before painting shall Sa2.5 grade iron surface treatment, construction is prohibited into the water, dust, oil painting to ensure quality. (2): coal tar epoxy anti-corrosion steel coal tar epoxy paint coating ratio: Group A (base), Part B (hardener) = 20kg (20kg / barrel): 1 kg curing agent (or according to the manufacturer informed the proportion of the ratio of construction). (3): coal tar epoxy coal tar epoxy paint steel construction ratio methods are: Group A big mouth open, will join the Group A fair share of Part B, stir evenly. Aging for 30 minutes, the coating can be carried out. (4): coal tar epoxy paint with the distribution requirements with the use of paint after matching must be used within six hours. Not finished with the material to be sealed. (5): rainy days or when the relative humidity is greater than 75% to stop construction. For severe corrosive media sites, the proposed multi-channel brushing. (6): coal tar epoxy paint products should be stored in a cool dry place, the construction site to avoid direct sunlight, separated from fire, away from heat. (7): coal tar epoxy anti-corrosion steel coal tar epoxy paint effective storage period of 12 months. The use of coal tar epoxy resin modified coal tar epoxy paint, combines the advantages of coal tar pitch and epoxy get acid, alkali, water, solvent, oil and adhesion, color retention, thermal stability, good electrical insulation coating. The coating is a 1960s anti-corrosion coatings appear. With the increased production of epoxy resin, the paint in the United States, Japan, France obtained the rapid development, accounting for half of the epoxy coating.
