HX-333 organic fluorine anticorrosive coating is made of organic fluororubber and silicone to form an interpenetrating net structure of elastomer. It is cured at room temperature, acid and alkali resistant, and has strong weather resistance. It can be used for a long time at -35-350 °C and is widely used in chimneys. The inner wall and the underground pipe network structure are used for anti-corrosion and anti-fouling. The anti-corrosion of the inner wall of the chimney can be made of acid-resistant and high-temperature resistant rubber (silicone rubber) as the primer, and it is bonded with SS-333 with a tackifier to form a three-dimensional network surface layer with good elasticity and anti-corrosion impact ability. The general temperature of the flue gas is around 60C-300°C, the flue gas flow rate is generally above 5 m/s, the particle size of the dust particle material is 0.3 mm, the dust concentration is above 10%, the relative humidity is 3-10%, and the ash powder is contained. And various corrosive components, such as sulfur dioxide, hydrogen chloride, nitrogen dioxide and the like, even flue gases contain highly corrosive gases such as hydrofluoric acid. SS-33 combined with Shishen 888 can effectively prevent corrosion Hardness (A): 25-31 21-25 Tensile hardness Map≥12 Elongation%≥110
