Two cloth four oil anti-corrosion steel pipe for water supply, epoxy coal tar anti-corrosion spiral steel pipe manufacturer Guanghui Manufacturing

Description :

　　At present, there are a wide variety of water supply materials, and our focus is on introducing new indoor and outdoor water supply pipes, as well as introducing some new high-performance application points that have been used in the past. Below are two main categories of pipe materials used: outdoor water supply pipe IPN8710 drinking water anti-corrosion steel pipe. Price precautions: 1. The product should be stored in a cool, ventilated, and dry place, away from fire sources, and kept away from heat sources. 2. This product is a thick paste coating that can be applied with a thick coating to avoid sagging. After opening the bucket, it can generally be brushed without adding diluent. 3. After the coating has been stored for too long, there may be slight precipitation, and it should be stirred before use. After the coating is prepared, it should be cured for 20 minutes in summer and 1.5-2 hours in winter before application. Generally, it should be used up within 8 hours, otherwise the viscosity will thicken and it will be difficult to apply. 5. After the surface of the primer is dry, the topcoat can be applied. The interval at room temperature should not exceed two days, otherwise it will affect the interlayer bonding. The time gap between applying each layer of topcoat should also be based on surface dryness. "IPN" is an abbreviation for "interpenetrating polymer networks" in English, translated as interpenetrating networks in Chinese. Interpenetrating network polymer is a new type of polymer anti-corrosion coating researched and developed in the past one or two decades. It has excellent properties of extraordinary polymer materials and is one of the hotspots in the development of polymer materials today, known as the "alloy" of polymers.

　　Epoxy coal tar anti-corrosion coating is composed of two main components: epoxy and coal tar. It is a two-component coating of A (epoxy) and B (curing agent), which has excellent adhesion, toughness, moisture resistance, water resistance, and chemical resistance. It has the performance of preventing various ions from passing through the paint film and has the characteristics of expansion and contraction with the coated object. The paint film never falls off or cracks. Thickness of 0.5-1.0mm. Epoxy coal tar is a cost-effective form of anti-corrosion, and engineering tests have shown that using epoxy coal tar combined with cathodic protection. Oil and gas pipelines have been used for 20 years without any corrosion.

　　The components 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, rigid fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. The B component is a modified amine curing agent or a curing agent as the main material, and is made by adding pigments and fillers. When this product is sold, components A and B are supplied together. During construction, they are mixed in proportion and mixed evenly before being used up within the specified time. The scope of application is mainly used for the anti-corrosion of the outer wall of buried or underwater steel oil, gas, water, and heating pipelines. It is also applicable to the anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, refinery and chemical plant equipment, as well as the waterproofing and leakage prevention of concrete structures such as concrete pipes, sewage tanks, roof waterproof layers, sanitary rooms, basements, etc.

　　Product features; 1. This product is a high-performance anti-corrosion coating with a smooth, dense, and hard coating, strong adhesion, excellent salt alkali resistance, seawater resistance, soil microbial corrosion resistance, and resistance to plant root and stem penetration. The composite use of paint and fiberglass cloth can enhance the mechanical properties of the anti-corrosion layer. 2. Room temperature coating, natural curing, easy to apply, can be manually or mechanically applied, especially suitable for on-site use.

　　Epoxy coal tar coatings are divided into two types based on their functional applications: epoxy coal tar primer and epoxy coal tar topcoat. Our company's epoxy coal tar primer is a solvent based product; Epoxy coal tar surface paint is a series of products, divided into solvent-free type (GH201) and thick slurry type (GH202) according to solid content. It is also divided into temperature resistant type (used within 150 ℃, with W added) and standard type (used within 100 ℃) according to the heat resistance temperature of the coating during use, for users to choose according to the actual requirements of anti-corrosion engineering. The enterprise standard for this product is Q/DH02-2009 "Liquid Epoxy Anti corrosion Coating", and its technical indicators are equivalent to the Chinese petroleum and natural gas industry standards SY/T0447-96 "Technical Standard for Epoxy Coal Tar Asphalt Anti corrosion Coating of Buried Steel Pipeline" and SY/T0457-2000 "Technical Standard for Internal Anti corrosion Coating of Liquid Epoxy Coating for Steel Pipeline". It also meets the requirements of the American Water Works Association standard AWWAC210-03 "Internal and External Anti corrosion Coating of Liquid Epoxy Coating for Steel Water Pipeline".
