Product Description:

    The expansion of Zhen Zhuyan is a kind of white or light colored high quality thermal insulation material which is made of acid volcanic glass lava (Zhen Zhuyan) by crushing, screening to a certain size, and then by preheating, instant high temperature baking. Perlite expansion and become a light, multi-functional new materials, the particle interior is honeycomb structure, non-toxic, tasteless, no rot, non flammable, acid and alkali resistance. And the performance of different products made with different binders, with apparent low density, low thermal conductivity, good chemical stability, temperature range, low moisture absorption ability, and non-toxic, tasteless, fire prevention, sound absorption and so on characteristics, widely used in various industrial sectors.

Expanded perlite production process:

   From the mining of ore by mechanical crushing, vibrating sieving machine with certain particle size distribution in the ore, expansion plant choose according to different purposes. Perlite ore materials of the moisture content of 4-6%, due to the high water content, after heated to a high temperature, rapid evaporation of moisture will cause perlite burst. Therefore, we should first perlite invalid water content removed prior to expansion, to preserve normal expansion required moisture (water). Through a great deal of experiments of the manufacturer and laboratory summary of the expanded perlite effective moisture content between the 2.2-2.4%, after the expansion of the effect best, expansion ratio (i.e. the maximum bulk density minimum). Therefore, the expanded perlite production process should include preheating, expansion of two key processes.
