Problems solved by technology

In the pure low-temperature waste heat power generation project, the air duct lining and related parts need to withstand the washing of high-concentration dust-laden airflow at a certain temperature, the corrosion of alkali-containing airflow, and the lining wall is thin, requiring small heat loss and heat insulation effect OK, so plastic ramming materials must be used for ramming and smearing construction. The service life of existing plastic ramming materials is generally 6 months, which is relatively short

Abstract

The invention relates to an abrasion-resistance plastic beater of low-temperature left-heat generator, wherein it uses boule, silica, boule powder, plastic clay, and alumina powder as base material; uses hot hardness microcosmic salt as adhesive; beats and shapes with plastic technique. The inventive product has high strength and abrasion resistance, while its service life can reach 24 month.

Description

Technical field [0001] The invention belongs to a high wear-resistant material used in building materials, metallurgy, and petrochemical industries, in particular to a highly wear-resistant plastic ramming material. Background technique [0002] Building materials, metallurgy and other industries are traditional large energy consumers. Take the 5000T / day large-scale rotary kiln in the cement industry as an example. The annual energy consumption is 87 million KW. Nearly 1,000 degrees of clinker falls from the kiln head into the grate cooler. Making full use of the huge heat has caused environmental pollution. In order to save energy and protect the environment, the National Development and Reform Commission requires the cement industry and metallurgical industry to realize the comprehensive utilization of waste heat, and support the construction of pure low-temperature waste heat power generation projects. [0003] Plastic ramming materials with high wear resistance, impact resistan...
