Expanded perlite powder
?
? ? ?A natural acidity glass felsic volcanic lava non metallic mineral resources, including perlite, pitchstone and obsidian rock, three only a crystal water content.?Because in the 1000 to 1300 degrees under the conditions of the rapid expansion of the volume of 4 to 30 times, it is referred to as the expanded perlite.?General requirements >7 expansion to 10 times (>3 times of obsidian, available), about 70% of silica.?Are open pit mining.No dressing, just broken, screening can.
?
Main uses:
? ? ?Can be used as filter agent, catalyst, molecular sieve and rubber, fertilizer, pesticide carrier.?Widely used in construction, metallurgy, petroleum, machinery, light industry, water and electricity, water, foundry, medicine, food, forestry and other departments.?The thermal conductivity of the regular temperature was 0.0245 ~ K (0.048W/ - M), the high temperature thermal conductivity was 0.058 ~ K (0.175W/ - M), the low temperature thermal conductivity was 0.028 ~ 0.038W/ (K - M), the highest temperature was 800.?Used as efficient heat preservation, cold filled material.
?
Advantages:
1.Expansion perlite with its good insulation performance, superior stability properties of the good to be accepted by the market and play the effect, and the application scope, with the universal application, especially in refractory and heat insulating and energy-saving play excellent performance.
?
2.The breakdown of excellent performance, can be said to have.?Not only has good environmental performance, economic and social value of widely used, with very convenient construction, easy maintenance, impact performance is better than other any kind of heat insulating material, excellent heat resistance and good fireproof performance.
?
3.Which durability and the same life of the building, completely broke the wall insulation materials of organic materials for the average service life of 25 years.?As rocks can inorganic heat preservation material system is inorganic product, never aging.?And it is seamless construction, so that the formation of the whole plastic wrap protection role of buildings.
?
4.Under the normal conditions?of use, such as the case of dry, cold, hot, humid, galvanic corrosion or insect, fungal or algal growth, and because of the sawtooth animal damage, collision and so on all sorts of invasion has no damage, greatly extended the life of the building.?The service life of the insulation material and the life of the building.
?
?
? ? ? ? ??Building roof and wall as heat insulation material, lightweight aggregate, agricultural and horticultural no soil cultivation, improved soil, water retention fertilizer, etc..
? ? ?Expanded perlite is used for a wide range of inorganic mineral materials, involving almost all fields.
For example:
1 oxygen machine, cold storage, transport liquid oxygen and liquid nitrogen can be used as a filling type thermal insulation material.
2 filtration for alcohol, oil, medicine, food, sewage and other products.
3 used in rubber, paint, paint, plastic, etc. filler and expansion agent.
4 for the sensitization agent.
5 for the adsorption of oil.
6 for agriculture, horticulture, improved soil, water retention fertilizer.
7 used in various kinds of adhesives and made of various specifications and properties of the profiles.
8 a lot of heat preservation and heat insulation for the roof and wall of the industrial furnace and building.
