High quality expanded perlite

Product Description

 ***0 ~ ***0 ℃ high temperature under the condition of its rapid expansion volume 4 ~ *0 times, therefore, collectively known as expanded perlite. General requirements expansion ratio > 7 ~ *0 times (black obsidian > 3 times, available), silicon dioxide by about *0%. Are all open-pit mining .

Expanded perlite can be used as a filtering agent, catalyst, molecular sieve, and rubber, the carrier of fertilizers and pesticides. Widely used in construction, metallurgy, petroleum, machinery, light industry, water and electricity, casting, medicine, food, agriculture, forestry and gardening departments and so on. Often temperature coefficient of thermal conductivity of 0.***5 ~ 0.**8 W/(m K), high temperature heat conduction coefficient is 0.**8 ~ 0.**5 W/(m K), low heat conduction coefficient is 0.**8 ~ 0.**8 W/(m K), the highest temperature **0 ℃. Used as a efficient insulation, cold insulation filling material.

The main purpose of the expanded pearlite:

As thermal insulation materials on building roof and wall, light aggregate, agriculture and horticulture soilless cultivation, soil improvement, retention of fat, etc.

Expanded perlite is a kind of inorganic mineral materials has a wide range of USES, almost involve all fields. Such as:

(1)oxygen generator, cold storage, liquid oxygen, liquid nitrogen as a filling type thermal insulation materials used in transportation.

(2)used for wine, oil, medicine, food, sewage filtering and other products.

(3)used in rubber, paint, coatings, plastics, and other fillers and KuoZhangJi.

(4)with Yu Minhua agent.

(5)used for adsorption of oil slick.

(6)Those used in agriculture, horticulture, soil improvement, the retention of fertilizer.

(7)All landowners to cooperate with all kinds of adhesive made from a variety of specifications and performance profile.

(8)Was more of a large number of industrial kilns and building roof and wall of heat preservation and heat insulation.
