Abstract

The invention relates to an oxidation-resistance coating capable of effectively preventing carbon-containing materials from being oxidized in a high-temperature environment. The oxidation-resistance coating is composed of the following ingredients (by weight): 59-80% of wastewater and residue of polycrystalline silicon cutting fluid, 19-40% of methyl silicone resin and 0.2-5% of tetraethyl orthosilicate. The wastewater and residue of polycrystalline silicon cutting fluid are composed of the following ingredients (by weight): 15-65% of silicon carbide, 15-65% of metal silicon, 5-30% of silicon dioxide, 5-20% of iron and its oxides and 5-20% of polyethylene glycol. The concentration of methyl silicone resin is 30-50%.

Description

technical field [0001] The invention relates to a paint, in particular to an anti-oxidation paint and its application method. Background technique [0002] As a new energy industry, the solar energy industry is inseparable from the use of polysilicon wafers, and a large amount of cutting fluid waste will be generated during the production of polysilicon wafers. Cutting fluid waste is processed by centrifugation, pressure filtration, winnowing, alkali washing, pickling, etc. to obtain products with high added value such as polyethylene glycol and silicon carbide that meet the particle size requirements, so as to continue to be used in new cutting fluids . A large amount of waste residue will be produced during this treatment process. The main components of the remaining waste residue are: silicon carbide, metal silicon, silicon dioxide, iron and iron oxides, and polyethylene glycol. The common feature is that the particles are particularly fine, and most of them are The par...
