First, the configuration method of waterproof perlite insulation board:
Perlite powder 45-50%, water 5-7%, water glass 35-42%, hardener 4-6%, water repellent 1.5-2.5%, adhesive 1.3-2%. The invention has the characteristics of light weight, small thermal conductivity, strong water repellency, square shape and cutting, stable quality and low price, and is an ideal material for thermal insulation of industrial and civil building roofs and walls.
Second, the main features of waterproof perlite insulation board:
The perlite insulation board is light in weight and excellent in thermal insulation performance. Fireproof, dustproof, moisture proof, no deformation modification, non-corrosion and mildew, non-toxic, tasteless, water-repellent, good water-repellent rate of 98% or more. Construction safety is simple and easy, and natural ore can be used as raw material for roofing and wall surface bonding. Have good environmental protection.
Stellite impeller is designed for automobile engine especially some advanced automobile.
As its excellent wear and high temperature resistance.
We made is by stellite 6 and production process injection moulding .
This design has not used to real production and welcome to discuss it with our engineer .
