How to make artificial stone countertops with double - layer composite process
And then by the drying process, grinding and polishing from the composite plate.
???? The above-mentioned expanded perlite can form the concave spots after the rough grinding of the plate, and the cemented plate can form the pores in the dry and high temperature, and the porosity of the artificial stone resin is made up with the pore characteristics of the two Closely integrated with the composite artificial stone plate.
The cementitious material is subjected to sawing, coarse grinding, drying and heating to 55 to 75 ° C. Diluted artificial stone resin and curing agent are carried out on a cement board surface by means of a scraper or spray method. 0.15 -0.3 mm thickness Of the compound.
With the aforementioned preform pattern synthesis process, and then with the bulk mixture discharged in the mold box after the vacuum and pressed into a square material.
The use of high-strength white cement as the adhesive, if necessary, add cement enhancer, 0.5 to 3 times the cement accumulation of less than 2 mm diameter expansion of perlite as filler, using the size of the marble as the aggregate.
