Perlite is a glassy rock formed by rapid cooling of acidic lava from volcanic eruptions,

Perlite is a glassy rock formed by rapid cooling of acidic lava from volcanic eruptions. It is a white granular material with a honeycomb structure. Perlite deposits include perlite, obsidian and turpentine. The principle of perlite is that the perlite ore is broken to form a certain granularity of mineral sand, after preheating and roasting, rapid heating, the water in the mineral sand vaporizes, and expands inside the softened glassy mineral sand to form a porous structure, and the volume expansion is 10-30 times of non-metallic mineral products.

Perlite can be made into perlite products, with light weight, low thermal conductivity, sound absorption, no corrosion, no burning, acid and alkali, non-toxic and tasteless properties, is highly efficient and ultra-lightweight thermal insulation, heat insulation, sound insulation, decorative materials.

1. Construction field

Closed-cell perlite is a key material in the manufacture of moisturizing mortar, which is widely used in the interior and exterior walls of buildings. Due to the characteristics of perlite, it can be used for concrete aggregate; Light weight, thermal insulation, thermal insulation sound-absorbing board; Fireproof roof and light anti-freeze, shock-proof, fireproof, radiation-proof and other high-rise building engineering wall packing, mortar and other building materials.

2. Chemical industry

Used as filter aid and filler. Processed products can be used to make molecular sieve, filter agent, stain remover; Used for brewing, making juice, drinks, syrups, sugar, vinegar and other food processing and manufacturing industries to filter fine particles, algae, bacteria, etc. Purify all kinds of liquids; Chemical industry plastic, paint industry detoxification, purification of waste oil, oil dewaxing, fractionation of alkanes, hydrocarbons; As a filling agent for pigment enamel, glaze, plastic, resin and rubber industries; Catalysts in chemical reactions and well grout mixtures.

3. Horticulture

Perlite can modify soil, regulate soil compaction, prevent crop lodging, control fertilizer efficiency and fertility, and act as a diluent and carrier for pesticides and herbicides.

4. In the beverage, beer, pharmaceutical industry, closed-cell perlite can be used as filter ceramics, filter AIDS, etc.
5. In the chemical industry and furnace manufacturing industry, closed-cell perlite can be used as thermal pipe moisturizing, furnace insulation products and moisturizing products.

4. In the military industry, closed-cell perlite can replace expensive glass microbeads in flotation.
5. In the fire fighting industry, closed-cell perlite can be used to manufacture various fire fighting appliances.
