Expansion perlite

Expansion perlite (EXPANDED PERLITE) 
      Expanded perlite is preheated, baked instantaneous expansion by expaned perlite ore, which is made after an internal honeycomb structure of the white granular material.
Perlite Principle and the expansion of configuration: 
Expanded perlite is crushed by the ore,  dealed with the rapid heating (1000℃ above). After the moisture vaporization ores and minerals in the particles soften internal expansion, the formation of porous structure, expansion to the original 10-30 times. The expanded perlite can be sorted to 3 fonfiguarations by the technical conditions. They are the open hole (OPEN CELL), the obturator (CLOSED Cell), the hollow hole (BALLOON).

The expanded perlite main characteristics :
Light porous   Unburning insulation
Acoustic waterproof corrosion resistance

Brilliant Expansion Perlite

The brilliant expansion perlite is a new type material of thermal insulating and heat-resistantor.Using liquefied pertrolum gas as fuel and selectivly particle size of high quality graded perlite as raw material, the product shall be formed at a sudden and controlled high temperature. Compared to ordinary expansion perlite, the outstanding characteristics are is its low bulk density, low heat exchange coefficient as well as exhibiting symmetrical size. The product is mainly used for the storage of liqufid industrial gasses in double wall cold or storage sphere as a good low temperature insulation material。

Close-structure Expansion Perlite

Close-structure expansion perlite (also called glassy perlite) is a new type thermal insulating material after our nearly 10 years cooperation with domestic research departments. The success of the new type material breaked the technical monopoly by Armerica, Japan and France in Chinese market and upgraded overally the processing level in Chinese perlite industry, in the mean time saved a lot of foreign exchange resource for country. The profuct require special particle size perlite ore, and take expansion in electric furnace. By this way, especially the precisely controlling the temperature and the material’s retaining time in furnace , the surface of expansion perlite shall be melted and close all air cells. The apperance come out ball but cell inside. Compared to traditional open-structure perlite, besides the same thermal insulating and acoustic insulation properties, its outstanding characteristic is for a high intensity, low water absorbability as well as a good miscibility. This material is in a premising prospect to substitute partially for similar ones in lightweight fire-Residtant, glassy particle in explosive making industy.
