 ● glaze ball obturator perlite 
 1 ★ Products 

 ◎ Obturator perlite (also known as glass perlite), the product selection of special size requirements of ore in the furnace heating mode expansion, through the precise control of temperature and material endurance, so that the product surface melting, stomata closed The internal cellular structure, the appearance of micro-ball compared with the conventional porous perlite retains the insulation, insulation, soundproof characteristics, but also has high strength, low water absorption, easy and good characteristics. 

 Main characteristics of the 2 ★ 

 ◎ The product has high strength, low water absorption and dispersion. 

 3 ★ applications 

 ◎ can improve the fluidity of mortar, widely used in internal and external wall insulation mortar; 

 ◎ decorative panels, lightweight aggregate insulation board; 

 ◎ can replace part of the floating beads to use; 

 ◎ building, metallurgy, industrial kilns (lightweight refractory bricks) and other industry.
