Coating for garbage cremator inner wall

Abstract

The invention relates to a paint, in particular to a corrosion-inhibiting and crust-promoting paint of the internal wall of a garbage incinerator. Talcum powder with the proportion of 5 percent to 20 percent, aluminous powder with the proportion of 50 percent to 80 percent, silica powder with the proportion of 1 percent to 5 percent, bentonite with the proportion of 1 percent to 10 percent and fluorite powder with the proportion of 1 percent to 10 percent are taken as raw materials, borax with the proportion of 1 percent to 10 percent and sodium tripolyphosphate with the proportion of 1 percent to 5 percent are taken as bonding agents, tartaric acid conservant occupies the proportion of 5 percent to 10 percent, a proper amount of water is added, and a paste paint is formed after mixing, grinding and stirring. The paint has the advantages of being capable of preventing the castable of the internal wall of the garbage incinerator from corrosion and prolonging the service life of the internal wall of the garbage incinerator, and the paint is simple to be prepared and easy to be applied.

Description

Technical field [0001] The invention relates to a coating, in particular to a coating used for anti-corrosion and skinning-promoting inner walls of garbage incinerators. Background technique [0002] At present, the inner wall of the waste incinerator is made of high-aluminum refractory castables. Because waste incineration produces a large amount of harmful components such as alkali, sulfur, and chlorine, the content is much higher than that of other kilns. On the one hand, they will enter and deposit inside the refractory material along the opening pores of the refractory material, react with the refractory material, and form a new mineral phase, accompanied by volume expansion, causing the refractory material to burst and damage; on the other hand, the high temperature of the waste incineration material Motion scour will continuously wear the refractory material. Therefore, the inner wall of the garbage incinerator is the most damaged, and the service life is generally o...
