Core tip: Introduction: aluminum powder asphalt anti-corrosion coating is a special anti-corrosion coating for ship bottom, with excellent performance The anti-corrosion coating for the bottom of the ship is made of coal tar pitch mixed with aluminum slurry, auxiliary agent and solvent, which should be fully stirred and evenly used Features: the features of aluminum powder asphalt anti-corrosion coating for ship bottom are as follows: The coating film of aluminum powder asphalt anti-corrosion coating for ship bottom has strong adhesion, hardness, water resistance and good underwater rust resistance When the ship uses the cathodic protection system, the protection potential is not less than - 0.8 V (AgCl / sea water electrode), otherwise it will produce peeling, avoid exposure to the sun, and prevent pulverization Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: Introduction: aluminum powder asphalt anti-corrosion coating for ship bottom is a special anti-corrosion coating for ship bottom, with excellent performance The anti-corrosion coating for the bottom of the ship is made of coal tar pitch mixed with aluminum slurry, auxiliary agent and solvent, which should be fully stirred and evenly used Features: the features of aluminum powder asphalt anti-corrosion coating for ship bottom are as follows: the film of aluminum powder asphalt anti-corrosion coating for ship bottom has strong adhesion, hardness, water resistance and good underwater rust resistance When the ship uses the cathodic protection system, the protection potential is not less than - 0.8 V (AgCl / sea water electrode), otherwise it will produce peeling, avoid exposure to the sun, and prevent pulverization and cracking Quality index: see Table 1 for the quality index of aluminum powder asphalt ship bottom anti-corrosion coating Table 1 quality index of aluminum powder asphalt ship bottom anti-corrosion coating project index paint film color and appearance Silver Brown, paint film smooth viscosity (coating - 4 cups) / s ≥ 45-75 drying schedule dry / h ≤ 2 dry / h ≤ 24 covering power / (g · m-2) 50 immersion 3% brine 240 H (coating two coats of paint, dry film 80 μ m) paint film non foaming, non rusting physical parameters and construction reference: See Table 2 for the physical parameters and construction reference of aluminum powder asphalt ship bottom anti-corrosion coating Table 2 physical parameters of aluminum powder asphalt ship bottom anti-corrosion coating and construction reference project technical index specific gravity / kg / L 1.2 flash point / ℃ 29 dry film thickness / μ m 40 wet film thickness / μ m 70 theoretical paint dosage / kg / m2 (i.e without any loss) 0.09 (dry film 40 μ M meter) recommended coating number 2 re coating interval time / h 24 matching paint Surface coating, l44-82 iron red asphalt ship bottom paint surface treatment steel sandblasting or polishing derusting to expose metallic luster The temperature of the base material in the construction environment shall be higher than the dew point by more than 3 ℃, and the relative humidity shall be lower than 85% In rainy and snowy days, it is not suitable to spray, brush and roll the diluent (Note: adding diluent will reduce the dry film thickness) X-85-10% precautions: keep good ventilation on the site, strictly prohibit fireworks, welding and use explosion-proof equipment Solvent or paint mist is harmful to the body, adhesion to the skin may cause allergies, and serious skin ulcers Wear qualified and effective labor protection articles Those with slight discomfort can rest for a while, and those with serious discomfort can be sent to a doctor for treatment in time Scope of application: mainly used as antirust primer at the bottom of the underwater part It is also used as waterproof and anti-corrosion primer for steel surface in indoor, cavern, shipyard, underwater, underground and other environments not exposed to sunlight Such as: storage tank, normal temperature pipeline, facility equipment foundation, cold air equipment, air pipe, etc Packaging, transportation and storage: products are sealed in metal cans Transportation shall be carried out in accordance with the National Transportation Regulations for hazardous chemicals and inflammables Store in a cool and ventilated warehouse away from fire and heat source Valid for 12 months 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,
