Product introduction:

Hydrophobic perlite, also known as hydrophobic vitrified beads, is a new type of perlite product. Due to the continuous expansion of perlite application, perlite itself has the disadvantages of high water absorption and poor thermal insulation performance after absorption. The hydrophobic perlite product developed by our factory has greatly overcome the major problem of water absorption, which is less than 10%. The appearance of the product is white or light white, loose, good liquidity. Under the microscope, it is a sphere with silver white luster, hollow and hard shell.


Product features:

Hydrophobic perlite has the heat preservation and fire prevention effect of original perlite, and also has the characteristics of hydrophobic, water absorption less than 10%. It has good fluidity, low water absorption and more obvious insulation effect.


Product application field:

1. Hydrophobic glass beads are porous hollow particles with particle diameter of 0.15-1.5mm, which is the preferred filling material.

2. It has low bulk density in the range of 0.06-0.20g/cm3. Compared with other mineral fillers, the polymer fillers have less loading weight, less polymer consumption and lower product cost.

3. Low price, based on the small bulk density of hydrophobic glass beads, compared with other filling materials, the production cost is reduced when the weight is the same in the polymer.

5. The thermal conductivity is between 0.036-0.054 w / M.K. the hydrophobic glass beads can be used as thermal insulation materials.

6. Sound insulation, hydrophobic glass beads can block and absorb sound, can be used as sound insulation materials.

7. The main components of the glass beads are SiO2 and Al2O3, which are nearly neutral and stable in various solvents, acids, bases and salts.

8. Electrical insulation, hydrophobic vitrification good electrical insulation, as a filling material can be used in a variety of electrical switchgear and insulation materials.

9. Good thermal stability. Thermal stability over 1000 ℃, especially suitable for fire resistant, fireproof and flame retardant materials.

10. Flame retardant. Hydrophobic glass beads are inorganic non-metallic mineral products, which are less than 1000 degrees Celsius. They do not decompose at high temperature and are not easy to deform. As polymer filling materials, they can improve the flame retardant properties of polymers and are used in building materials and paint industry.

11. Low water absorption: the water absorption of hydrophobic glass beads is less than 10%.

12. Low shrinkage. Hydrophobic glass bead is one of the few low shrinkage filling materials that can meet the needs of the filling material industry. This problem is particularly important when it is loaded in a large proportion of polymer.

13. The density of fresh mortar and hardened specimen will be decreased by reducing the amount of water added in the light insulation mortar.

14. To improve the standard curing compressive strength and freeze-thaw resistance of lightweight thermal insulation mortar.

15. Reduce the shrinkage of lightweight mortar.
