Introduction of Hydrophobic perlite

Hydrophobic perlite is hydrophobically modified on the basis of expanded perlite to achieve excellent waterproof effect. Its thermal conductivity is low, generally around 0.045W/m.k, and the lowest is 0.041W/m.k. The outer surface has a sealed glass bulb, so thatHydrophobic perlite has high compressive strength and is not easy to be destroyed, which can greatly reduce the damage rate during use and effectively maintain the practical insulation effect. At the same time, the water absorption of the material is reduced, and the amount of water added to the proportion is reduced, so that the overall drying time of the material is significantly shortened, which helps to improve the construction efficiency.

Features and Applications of Hydrophobic perlite

1.Hydrophobic perlite is a porous hollow particle with a particle diameter of 0.15-5mm, with a low bulk density, between 0.05-0.20g/cm3, and is the first choice for filling materials. Compared with other mineral fillers, the amount is less, the loading weight is small, and the amount of polymer is saved, so the product cost can be reduced.
2.Electrical insulation, water-repellent vitrification and good electrical insulation. As a filling material, it can be used in various electrical switchgear and insulating materials. It has good chemical stability, strong water repellency and safe use. It can adjust and sensitize the density of latex and water gel explosives. It is an ideal density regulator for the production of latex and water gel explosives.
3.Sound insulation, Hydrophobic perlite can block and absorb sound, and can be used for sound insulation materials, sound insulation and sound absorption of buildings.
4.Acid and alkali resistance, the main components of Hydrophobic perlite are SiO2 and Al2O3, which are close to neutral, and are stable in various solvents, acids, alkalis, and salts. It is used for the transportation and storage of LNG on the ocean, marine pastures and high-strength solid buoyancy materials on the sea.
5.Low thermal conductivity, with a thermal conductivity of (0.036—0.054w/m.k). Hydrophobic perlite can be used for thermal insulation materials and thermal insulation materials.
6.Good thermal stability. The thermal stability exceeds 1000 degrees Celsius, and it is especially suitable for fire-resistant, fire-retardant and flame-retardant materials.
It does not decompose at high temperature and is not easy to deform. As a polymer filler, it can improve the flame retardant properties of polymers and is used in building materials and paint coatings industries.
7.Low water absorption rate: The water absorption rate of the Hydrophobic perlite is less than 10%, which is used for filling and reducing aggregates of reservoirs and dams.
