Zhengfeng rock wool products are made of high-quality natural rock (such as basalt dolomite) as the main raw material. The raw material is melted at a high temperature of more than 1450 ℃ through a cupola. A small amount of adhesive is injected into the four roller centrifuge discount machine to solidify and heat up, and then the rock wool insulation blanket pipe and plate shape are processed
The slag ball content of rock wool board of Zhengfeng external wall is low, and the cotton wire is slender and flexible, so it has low thermal conductivity and good thermal insulation effect
Because it uses natural rock as the raw material, it is A-class non combustible building insulation material with excellent high-temperature resistance. It does not produce toxic gas or molten dripping matter in fire. It is applied to thermal insulation of building structure and equipment to form a fire barrier and effectively delay the spread of fire
Sound absorption and noise reduction
A large number of slender and flexible rock wool fibers form a multi space interconnected structure, and numerous tiny air gaps exist. The internal structure makes Zhengfeng rock wool have the physical characteristics of sound absorption, noise reduction and elastic shock absorption
Zhengfeng exterior wall Rock wool board The h3h value of the liquid is neutral or weak alkaline, and it has no corrosion on carbon steel, aluminum alloy, copper, stainless steel, cast iron and other metal equipment as well as the components in buildings
Health and environmental protection
The rock wool board of Zhengfeng external wall does not contain asbestos, CFC or HCFC and other harmful substances are not used in the production process. It does not have the growth environment of microorganisms and does not breed mold.
Water repellent and moisture resistant
The results show that the moisture absorption rate is less than 0.2%, the mass moisture absorption rate is less than 1% and the hydrophobicity rate is more than 98% when exposed to the environment of 50 ℃ and 95% relative humidity for 96 hours
Zhengfeng rock wool, the best thermal insulation material, can greatly improve the energy-saving utilization efficiency of the whole building and equipment, reduce the consumption of cold and hot media by more than 85%, not only saving energy, but also reducing costs The energy saving achieved by using Zhengfeng rock wool as thermal insulation material can simply and effectively reduce the energy production required by heat energy and power supply. It is a direct and low-cost emission reduction means to reduce the greenhouse gas emissions of the whole society. It provides the most important energy conservation layer and the most important potential for the sustainable development of buildings.
