Anticorrosion pipeline is the preferred anti-corrosion steel pipe in water pipeline project, mainly used for urban water supply, water and other drinking water pipes.
There are many kinds of corrosive medium in water supply pipeline, such as acid, alkali, salt and oxidation IPN8710 anti-corrosion pipeline is the preferred water pipeline corrosion pipe, mainly for urban water supply, water and other drinking water pipes. There are many kinds of corrosive medium in water supply pipeline, such as acid, alkali, salt, oxidant and water vapor. The paint must have chemical lazy, acid and alkali salt corrosion. The coating should be fine, waterproof, Tough and plump.
Primer: Polyurethane, modified epoxy resin, non-toxic antirust pigment fillers, additives, etc., at room temperature curing constitute interpenetrating network, film structure fine, acid, alkali, salt, rust excellent , Strong adhesion
Topcoat: from epoxy, rubber resin modified, non-toxic anti-rust pigments, additives and other components. Chemical resistance Excellent, non-toxic, anti-microbial corrosion.
Pipeline in the transport and installation process may appear on the pipeline coating damage, pipeline installation and inspection after the end of the pipeline coating also need to fill the mouth injury 8710 anticorrosive coating Excellent water resistance, dedicated to food, drinking water and other equipment.
IPN8710 coating offers several advantages. It has good corrosion resistance, low water absorption rate, and high mechanical strength. The coating is non-toxic and suitable for applications involving potable water IPN8710 coated pipes can be used for both above-ground and underground installations, providing reliable protection against corrosion.
IPN8710 coated pipes are commonly used in various industries, including water supply, gas transmission, and underground piping systems. The coating helps to protect the steel pipes from corrosion, extending their lifespan and maintaining the integrity of the pipeline.
IPN8710 anti-corrosion is applicable when there are many types of corrosive media inside the steel pipe. The IPN8710 anti-corrosion primer is composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti-rust pigments and fillers, additives, etc., and is used for the anti-corrosion priming coating on the inner wall of the water supply pipeline; The IPN8710 anti-corrosion topcoat is modified by epoxy and rubber resin, and composed of non-toxic anti-rust pigments and fillers, additives, etc., and is used for the anti-corrosion topcoat on the inner wall of the water supply pipeline.
Steel surface treatment is mainly anti rust, the following is anti rust process:
First step is to clean, use cleaning solvent emulsion cleaning the steel surface, in order to achieve the removal of oil, grease, dust, lubricants and similar organic matter, but it can not remove the steel surface rust, oxide, solder medicine.
Second step is to right tools rust, rust tools you want to have to use a wire brush, wire brush to remove loose or warped oxide, rust and slag. To achieve the desired effect of the rust, the hardness of the steel surface must be based on the original extent of corrosion and the required surface roughness, coating, etc. to select the type of abrasive, the epoxy layer, two or three layers polyethylene coating, using mixed abrasive grit and steel shot blasting easier to achieve the desired effect.
Third step is to do pickling, chemical and electrolytic pickling generally use two methods, using only chemical pickling pipeline corrosion. Although chemical cleaning can achieve a certain surface cleanliness and roughness, but there are some pollution to the environment.

Finally emphasis on the importance of surface treatment in the production, strictly control the process parameters when anti rust.
