Product Overview

Description

 

 

Spot supply  agriculture perlite sand for improving soil property

 

 

 

 

 

Perlite is a kind of vitreous rock formed by volcanic eruption and rapid cooling. It is named for its pearl fissure structure.Perlite raw sand can be used as filler in rubber and plastic products, pigment, paint, ink, synthetic glass, heat insulation bakelite and some mechanical components and equipment after fine grinding and superfine grinding. Perlite has become a light and multifunctional new material after expansion. It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide application temperature range, small hygroscopicity, innocuity, tasteless, fireproof and sound absorption, and is widely used in various industrial departments.

 

 

 

 

The raw material deposit of expanded perlite is mainly the product of acid volcanic eruption rock.
