Manufacturer of anti-corrosion steel pipes for water supply pipelines

Description :

　　IPN8710 non-toxic drinking water anti-corrosion coating is a non-toxic drinking water coating with good anti-corrosion performance. Rust proof, non irritating, non-toxic after curing. The coating structure is dense, with good waterproof permeability, strong adhesion, and a tough and full coating. The domestic steel transaction situation is not ideal, but the overall inventory situation is normal and there has not been a significant increase. At the end of mid August, the steel inventory of member enterprises of China Iron and Steel Industry Association was 12.3384 million tons, an increase of 396800 tons on a ten day month on month basis, up 3.32%. Since its establishment, our company has been committed to the research and promotion of this product. While developing the performance maximization of this product, we also continuously promote its performance characteristics to customers in order to obtain more applications in various fields and expand its application scope. For such a new industry, it is both an opportunity and a challenge for us. Why is it called an opportunity? Because this product is newly developed, for the manufacturer, it is a new world, a new market exploration, and new development opportunities. And why is it considered a challenge? Because the development of a new market means the emergence of new industry standards and a new market order, companies need to stand out in such an environment. IPN8710 Primer: Composed of polyurethane polyethylene, modified epoxy resin, non-toxic 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. IPN8710 topcoat: composed of epoxy, rubber resin modification, non-toxic anti rust pigments and fillers, additives, etc. Excellent chemical resistance, non-toxic, and resistant to microbial erosion. Coating method: Brush coating or high-pressure airless spraying Application: IPN8710 primer is used for anti-corrosion primer coating on the inner wall of drinking water pipelines; IPN8710 topcoat is used for anti-corrosion topcoat coating on the inner wall of water supply pipelines.

　　The surface treatment of the oil coated anti-corrosion steel pipe adopts shot blasting or sandblasting rust removal treatment to reach Sa2 level and Sa 2.5 level. When construction conditions are limited, manual or power tools can also be used to remove rust to St 3 level. After the steel surface treatment is qualified, it must be painted as soon as possible before rusting. The concrete surface should be completely dry (with a surface moisture content of less than 6%), and epoxy coal tar five oil three cloth anti-corrosion steel pipes should be used to remove surface loose substances and present a smooth and solid surface. Formulate adhesive. First, mix components A and B evenly, then mix them thoroughly in a 1:1 weight ratio of A to B and use immediately. The setting adhesive contains a fast drying curing agent, and the Weinan epoxy coal tar anti-corrosion steel pipe has a fast curing speed but a short service life. Therefore, it must be used up within 1 hour in summer and 2 hours in winter after preparation. The reinforced epoxy coal tar anti-corrosion steel pipe should be prepared and used immediately during construction to avoid solidification in the batching bucket and inability to use. Normal temperature glue should be used above 5 ℃, low-temperature glue should be used between minus 8 ℃ and 5 ℃, and the ambient temperature should be stable below minus 8 ℃. Ultra low temperature glue should be used (when the temperature is low, the curing time is too long, which is a disadvantage of epoxy coal tar pitch. If the project schedule is tight, low-temperature glue and ultra-low temperature glue can be poured into the ditch after they are dry). Various types of adhesive have different compositions and cannot be mixed.

　　Epoxy coal tar anti-corrosion spiral steel pipe is commonly referred to as "several cloth and several oil". Common types include one cloth and two oil, three oil and two cloth, three cloth and four oil, three cloth and five oil, six oil and two cloth, four cloth and six oil. The components of epoxy coal tar anti-corrosion spiral steel pipe are epoxy coal tar primer and topcoat, both of which are mainly composed of epoxy resin and coal tar as film-forming materials, and are made by adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. Appearance: Primer component A is iron red, component B is black, and the topcoat is black. It has excellent resistance to chemical media corrosion and good physical and mechanical properties, good adhesion, tough coating, as well as excellent electrical insulation and anti permeability, anti stray current and anti microbial erosion. After film formation, it can reduce the number of construction passes. The main implementation standards are SY/T 0447-96 "Technical Standard for Epoxy Coal Tar Anti corrosion Coating of Buried Steel Pipelines" and SY/T 0457-2000 "Technical Standard for Liquid Epoxy Coating Internal Anti corrosion Coating of Steel Pipelines".
