Expanded perlite plate and manufacturing process thereof
The invention relates to an expanded perlite plate and a manufacturing process thereof, relating to a formula and a technological process of expanded perlite plates. The process comprises the following steps: starting from grading of chromaticity and granularity of expanded perlite, metering the expanded perlite in volume, metering the other components in weight, adding a water repellent into sodium silicate, performing uniform liquid-liquid mixing, pressurizing or air-entrapping so as to be atomized or semi-atomized, performing uniform solid-liquid mixing with the selected expanded perlite, distributing, netting, pressing, molding, drying, shaping, checking the quality and packaging. The product is high in cost performance, high in quality, low in cost, attractive in appearance and wide in application, and various performance indexes are superior to the national standard.
