perlite sand for insulating layer the lowest price
Introduction of perlite Also called cryogenic equipment insulation perlite with expanded perlite, it is a kind of acidic volcanic glass lava by crushing, preheating, roasting expansion with porous structure, made of white, loose granular materials, has a small capacity, low thermal conductivity, good chemical stability and noncombustible, non-toxic, tasteless, sound-absorbing features.Its colour and lustre, bulk density, the specification is similar to normal expanded perlite.
Characteristics of perlite 1, perlite is a kind of adsorption ability very strong material, it has good invasive, invasive said pearl sand surface heat energy that is released after being soaked. 2, perlite is has a small capacity, low thermal conductivity, chemical stability, good material. 3, perlite and noncombustible, non-toxic, tasteless, can sound-absorbing materials, in the industry have good use effect.
Perlite chemical composition
Perlite usage Perlite is mainly used for large scale cryogenic thermal insulation construction, such as oxygen air separation units, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport and other transport.This product has a good cryogenic insulation performance.
1, is perlite insulation materials, can be used to do some roof insulating layer.Heat insulation effect is better, some still can be used for crops cultivated soil configuration, etc. Use.
2, making insulating brick used in the construction industry, etc.
3 and production of washing powder, washing powder perlite is irreplaceable by other materials, its structure and the screen is very strict.
