　　Corrosion prevention inside pipelines; IPN8710 anti-corrosion steel pipe is a type of anti-corrosion steel pipe used in drinking water pipelines. This product uses spiral steel pipes as conveying pipelines, and then applies IPN8710 anti-corrosion coating to the spiral steel pipes for anti-corrosion treatment. This product is a two-component, high solid coating primarily composed of epoxy resin. Divided into primer and topcoat. Component A is composed of epoxy resin, pigments, additives, and auxiliaries. Component B is a curing agent formulated with modified amines. Good durability, the cured epoxy resin film is tough and water-resistant, and does not pollute water. Strong adhesion, with good adhesion between paint films. Excellent anti rust and water resistance, using excellent anti rust materials to ensure its anti rust performance. It has good mechanical strength, tough paint film, wear resistance and impact resistance. High solid content and thick coating. Cure at room temperature to form a film. No need for large baking equipment. Widely applicable for inner wall coating of water supply equipment such as drinking water tanks, water pipelines, water tanks, and water towers, as well as for use in sugar and grain cargo holds. It can also be used as a cooling tower for swimming pools, power plants, and as an inner wall coating for metal and concrete used in fuel oil and gasoline installation.

　　Overview of IPN8710 Anti corrosion Steel Pipe for Drinking Water Pipeline: There are many types of corrosive media in the water supply pipeline, including acid, alkali, salt, oxidant, and water vapor. The coating must have chemical inertness, acid and alkali salt corrosion resistance, and the coating should have a dense structure, good waterproof permeability, strong adhesion, and abundant toughness IPN8710 Primer: Composed of polyurethane polyethylene, modified epoxy resin, anti rust pigments and fillers, additives, etc., it solidifies at room temperature to form an interpenetrating network. The coating structure is dense, resistant to acid, alkali, and salt, with excellent anti rust performance and strong adhesion.

　　Construction process of IPN8710 series anti-corrosion coating:

　　1. Corrosion prevention mechanism with rust: When the two monomers of IPN are mixed in proportion, a reaction occurs immediately. At the beginning, the viscosity of the mixture is very low, and its penetration rate is fast. It can directly penetrate to the surface of the steel and separate the rust body from the steel surface, then surround it. As the reaction time increases, the mixture gradually solidifies to form an IPN mesh film, which adheres to the surface of the steel and resists the progress of rust.

　　2. The pre-treatment of anti-corrosion parts eliminates oil stains, dust, welding slag, oxide scale, and loose rust on the surface of anti-corrosion parts, keeping the surface of anti-corrosion parts dry and free of stains.

　　3. Paint preparation: The amount of paint should be estimated, mixed in proportion, thoroughly stirred, and used up within the specified time

　　4. Spray anti-corrosion parts should not be sprayed less than three times, divided into three situations according to the anti-corrosion level: (1) Ordinary anti-corrosion construction: first apply two layers of primer (colorless), and then apply two layers of topcoat. (2) Strengthen anti-corrosion construction: First apply a layer of primer (colorless), then wrap a layer of degreased fiberglass cloth, and at the same time brush a layer of topcoat, and finally spray the topcoat. (3) Strengthen anti-corrosion construction: First apply a layer of primer (colorless), then wrap a layer of degreased glass fiber cloth and apply a topcoat, then wrap a layer of degreased glass fiber cloth and apply a topcoat, and finally spray the third topcoat. Mechanical spraying or manual painting can be used for the construction of various anti-corrosion levels mentioned above.

　　IPN8710 interpenetrating network heavy-duty anti-corrosion coating is a two-component coating, with Group A base material: resin, initiator; Group B base materials: active monomers, catalysts. When group A and group B are mixed in equal quantities, the three networks interpenetrate at the molecular level to form an interpenetrating polymer network (IPN) structure, producing a synergistic effect. The coating forming network has strong adhesion, good flexibility, and resistance to corrosive media such as acid, alkali, and salt. Further improving the toughness, strength, adhesion, Kang permeability, and chemical inertness of the coating, the coating has better performance. By forming IPN to improve the performance of high polymers, it is a new type of high polymer blending technology. Since the production of IPN8710 interpenetrating network coating in China in 1987, different resins and pigments have been used for technological improvement to resist different corrosive media. Special coatings have been developed for water pipeline anti-corrosion coating, chemical atmospheric anti-corrosion coating, gas cabinet, pipe anti-corrosion coating, oil storage tank, oil pipeline anti-corrosion coating, etc. The comprehensive performance of this series of coatings is as follows: 1. Simple surface treatment; 2. Excellent anti-corrosion performance; 3. The performance price ratio is reasonable.
