The material properties and technical requirements of putty use are as follows:
Carboxymethyl cellulose: white floc, strong hygroscopicity, soluble in water, mainly plays a role in improving the viscosity of putty in putty.
Big white: There are two kinds of blocks and powders. The white color is required to be pure white, and the fineness is required to pass the 8O mesh sieve.
Gypsum: It is made of plaster white powder, which is a gas-hardening cementitious material. It can not be damp and rain. It is strictly forbidden to use damp and agglomerated plaster.
Talc: Soft and smooth and light.
Polyvinyl acetate emulsion (abbreviated as emulsion): This emulsion prevents the precipitation of other materials, prevents the putty from falling, and improves the operation performance of the putty.
