Problems solved by technology

In the past, the perlite insulation board was formed by adding perlite particles with binder, pouring them into a plate press machine under manual stirring, and then putting the pressed insulation board into a drying room at a high temperature of 200-300°C for 18-24 hours. Hours of drying, because its raw material is mainly perlite, its perlite texture is lighter and softer, and the insulation board produced has a high density and poor strength, and some parts of it are broken during the construction process and cannot be used
At the same time, since the production process is mostly artificial and the output is low, it is far from meeting the needs of the existing construction market.
