Coating knowledge: foreign anticorrosive coating technology

Core tip: epoxy resin composite coating epoxy resin composite coating system is suitable for protecting pipeline from abrasion, severe environmental conditions and external corrosion This kind of anticorrosive coating is more advanced than American amo 370 pipeline coating (ap370plc) It is a long-term anti-corrosion barrier, suitable for the transition from land to air, forming a chemical barrier, which can block most chemicals, including caustic soda, dilute acid, salt solution, water, steam and petroleum solvent It is a wet laid product, so it can be used not only for straight pipes but also for bends, T-pipes and other external structures Due to its durability, the Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: epoxy resin composite coating epoxy resin composite coating system is suitable for protecting pipelines from abrasion, harsh environmental conditions and external corrosion This kind of advanced anticorrosive coating includes American amo 370 pipeline coating (ap370plc) It is a long-term anti-corrosion barrier, suitable for the transition from land to air, forming a chemical barrier, which can block most chemicals, including caustic soda, dilute acid, salt solution, water, steam and petroleum solvent It is a wet laid product, so it can be used not only for straight pipes but also for bends, T-pipes and other external structures Due to its durability, the system greatly reduces scheduled maintenance This kind of material has the following characteristics: the mixing ratio is 1:1 (equal mixing); color: Part A is white, Part B is black, light gray after mixing & curing; ap370plc kit can provide 1 quart, 1 / 2 gallon and 1 gallon barrel tape with 1 roll of fiberglass tape (Note: 1 gallon kit can cover about 25 square feet of pipe surface); continuous working temperature: - 51 ° C to 91 ° C; Service life / working time: 24 ° C, about 45 minutes; curing time: 29 ° C, about 2 hours; UV protection is provided; the storage period of epoxy resin 370A & B is 2 years The ceramic filled coating system used for coating is designed for steel, concrete, etc In the chemical and related industries, it can be used to protect the surface from contact with reinforcement It is designed as a non structural pipe coating, which is more durable than traditional tape coating, paint and wax The system is mainly used to prevent external corrosion of girth welds, ground contact surfaces, exposed ground lines, and top coats of AMO pipe coverings The ap385pmc can be applied to vertical, elevated and horizontal surfaces with a brush thickness of 30-40 mils (762-1016 microns) The installation procedure is: finish surface preparation Mix a and B Brush the mixed ap385pmc onto the treated surface with a suitable hard brush After a short period of curing, it will become flat and smooth Generally, two coats are not required, because the thickness of the first coat is usually enough If a second coat is required, it must be applied after the first coat is cemented (firm, but still sticky on the touch) Solidification The fast curing phenolic epoxy coating with 100% solid content is completely harmless Among them, norvik R200 is excellent in this field, which can be used as coating for pipeline repair The maximum operating temperature of these pipelines is as high as 200 ℃ This two-component, solvent-free epoxy coating can easily achieve a dry film thickness of 40 mils (1 mm) This product provides better adhesion and wear resistance Applications: girth welds, valves, devices, bent and irregular shape repair pipes, new pipes or other metal substrates requiring corrosion protection Material features and advantages: 100% solid content, phenolic epoxy resin; no volatile organic compounds, no isocyanate; phenolic Chemistry - used in pipes, operating temperature up to 200 ℃; higher wear resistance; norvik-r200 can be sprayed or manually operated; better adhesion on exposed steel and epoxide powder materials; excellent cathode stripping performance, adhesion and elasticity Recommended thickness: wet film: up to 40 mils / layer dry film: up to 40 mils / layer polymer composite material is specially used for protection system application The representative materials in this field are ee-11 produced by AK company of the United States, which has underground pipeline coating for all segments, and spray phenolic ceramic filled coating, suitable for corrosive water environment When the temperature rises to 300F, the immersion effect is very good Resist strong wear The high elasticity enables ee-11 to be used for tubesheet and underground piping Ee-11 primer containing zinc phosphate reduces corrosive penetration Whether fresh water, salt water or salty, pipe / segment joint is the key point of erosion, corrosion & leakage, which is related to whether the unit efficiency will be degraded The AK pipeline coating is accompanied by a 10-30cmdt coating, which can effectively seal the area to improve efficiency & prevent future erosion and corrosion The ee-11 system with good flexibility can prevent cracks, cracks and leakage caused by bending and thermal pressure For underground pipelines, ee-11.5 has good adhesion, no sag or depression, 5-10 mil DFT Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
