Overview
Description:
Volcanic stone is a functional kind of environmental protection material.
It is a kind of precious and polyporous stone, and formed by volcanic glass ,mineral and air bubble in the process of volcanic eruption.
It contains sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt, molybdenum, and other dozens of minerals and trace elements.
It has no radiation .It has far infrared magnetic wave ,can be used for Slide-proof, acid & alkali proof ,Sound absorbing and insulation ;
Processing:
Volcanic stone ore is used as raw material, processed by crushing, screening, dust removal and other processes. The color is mainly red and black, and is rich in various elements such as potassium, magnesium, iron and phosphorus. The pores are smooth, light in weight and not easily broken, and the gas permeability is good to absorb water without water logging;
Properties:
1.It has lots of holes.
2.Weight is very light.
3.Perfect intensity
4.Heat preservation and thermal insulation, noice insulation.
5.Fireproofing
6.Corrosion and acid-base resisting
7.Non-pollution and no radioactivity, environment protection
