Due to the vicious market price competition of glazed microbeads, many construction companies buy the so-called "glazed microbeads" at low prices in order to save the cost of glazed microbeads, which are mostly expanded perlite with open holes. When this opened expanded perlite is mixed with water on the site, it absorbs very much water.
At present, due to the vicious market price competition of glazed microbeads, many construction companies buy the so-called "glazed microbeads" at low prices in order to save the cost of glazed microbeads. In essence, most of them are expanded perlite with open holes. When this opened expanded perlite is mixed with water on the site, it absorbs very much water. After the inorganic vitrified microbeads thermal insulation slurry containing too much water has stood for a period of time, the water will slowly sink inside the slurry. By using good quality water retaining agent (cellulose ether) and increasing the amount of water retaining agent, the precipitation of water inside the open perlite with a relatively large amount of water absorption can be slowed down, but it can not be completely prevented. This will lead to inorganic thermal insulation mortar workability loss is relatively fast.
Inorganic thermal insulation mortar is a new type of thermal insulation and energy-saving mortar material used for building interior and exterior wall painting. According to the different cementitious materials, it is divided into cement based inorganic thermal insulation mortar and gypsum based inorganic thermal insulation mortar. Energy-saving inorganic thermal insulation mortar has the characteristics of energy saving and waste, heat insulation, fire prevention and freezing, aging resistance and low price, and has a wide range of market demand.
