Subcontract power plants, thermal power plants, steel mills, and business units: desulfurization of the inner wall of the chimney, anticorrosion of the inner wall of the absorber tower, construction of foam glass bricks, anti-corrosion construction of glass flake and high-altitude construction projects, aerial maintenance, high-altitude installation, high-altitude paint anti-corrosion, high-altitude cleaning and beautification, Waterproof plugging, waterproof coating paint and petrochemical chemical equipment corrosion protection and chimney smoke flue gas desulfurization environmental protection dust, environmental health testing and other high-altitude operations.
High-temperature vinyl glass flake clay preservation
Stain is generally added ceramic wear-resistant material to increase the wear characteristics. Wear-resistant glass flake is mainly used in spray towers of absorbent towers or areas where grout wear is severe (where agitators are installed).
Anti-corrosion of the pool can use epoxy coal tar anti-corrosion paint, acid and corrosion resistance and high temperature vinyl resin paint adhesion, tough film, high mechanical strength, good anti-chemical corrosion resistance, widely used in desulfurization tower absorption tower, underground pipeline And the protection of the lower tank of the gas storage tank and the internal and external wall of the other pipeline anti-corrosion desulfurization tower use vinyl glass flake clay heavy anti-corrosion. According to the following practices:
1. The spraying surface of the inner wall of the equipment shall be flush, the surface of the weld shall be smooth, there shall be no welding slag, welding burrs and burrs, and the corners at the inner edge of the flange joint must be ground to a smooth transition with a fillet radius of not less than 5mm. The internal parts are ground to a rounded transition (carbon steel section) with a rounded corner radius of not less than 2mm.
2. The aluminum spraying surface of the equipment must be surface treated according to the following steps and requirements: (1) Purification treatment: The sprayed aluminum surface needs to be strictly cleaned of grease and dirt.
(2) Coarsening treatment: The surface after the purification treatment needs to be grit blasted. The surface cleanliness after sandblasting should meet the requirements of Sa3 grade in GB8923-88. No attachments such as oxide scale, rust dirt and old coating are allowed. (3) After the surface treatment is qualified, the waiting time for aluminum spraying should be shortened as much as possible, and the sandblasted surface should be strictly protected to prevent moisture, dust and oil pollution.
2. The aluminum material used for spraying should meet the requirements of L1 in GB3190-82. The sprayed layer should not be less than 5 layers and the coating thickness should be 0.3mm.
3. The spray layer must not contain defects such as air bubbles, cracks, holes, and sheet slag or loosely adhering particles.
4. After the appearance and thickness inspection of the sprayed aluminum layer is qualified, the etching treatment is first performed with phosphoric acid, and then low viscosity resin is applied to close the coating pores.
5. The sprayed aluminum layer needs a blue dot test to check its compactness. No blue dot is acceptable.
6. The internal anti-corrosion shall be carried out after the ladder platform and other welded parts are welded. No welding shall be carried out on the equipment after anti-corrosion construction.
7. It is forbidden to spray paint on the stainless steel surface of the equipment.
