Rock wool originated in Hawaii. After the first volcanic eruption on the island of Hawaii, the inhabitants of the island found a rock on the ground that melted and softened. This is the rock wool fiber that was originally recognized by humans. The production process of rock wool is actually simulated. In the natural process of Hawaii volcanic eruption, insulation rock wool products are made of high-quality basalt and dolomite as the main raw materials. After being melted at a temperature above 1450 °C, they are centrifuged into fibers at a high speed using an internationally advanced four-axis centrifuge. The agent, the dustproof oil and the water repellent are collected by the cotton collecting machine, passed through the pendulum method, and the three-dimensional method is used for the cotton to be solidified and cut to form rock wool products of different specifications and uses.

Rockwool can be made according to different purposes: felt, strip, tube, granular, plate, etc., used in: nuclear power plants, power plants, chemical plants, large kiln insulation; external thermal insulation of buildings, roof and curtain wall insulation, insulation belt Cabin, onboard sanitation unit, crew lounge, power warehouse; factory soilless cultivation of vegetables, melons and flowers.

Today, with the rapid development of human civilization, the natural environment has been greatly damaged. Environmental issues have become a serious issue that all mankind must face together. Energy conservation and emission reduction, and vigorous promotion of low-carbon and environmentally friendly green buildings have become the focus of attention of the whole society. At the World Climate Conference in Copenhagen, our government has solemnly promised to the world that by 2020, the carbon dioxide emissions per unit of GDP will fall by 40%-45% compared with 2005. The building energy consumption accounts for more than 30% of the total energy consumption of human beings. It is imperative to develop new building materials for energy conservation and emission reduction and low carbon economy. In recent years, the fire caused by improper selection of external thermal insulation materials is shocking and has caused great losses to the lives and property of the people. Rock wool products, such as rock wool insulation board are internationally recognized as the "fifth conventional energy source" for their excellent fire and heat insulation properties. "The main energy-saving materials in the middle. Every 1 ton of rock wool products used for insulation in the building can save at least 1 ton of oil per year, which is in line with low carbon, energy saving and emission reduction trends. Therefore, as an ideal building insulation material - rock wool, it is facing unprecedented Development opportunities and challenges.

In order to speed up the structural adjustment and transformation and upgrading of the rock wool industry, curb low-level redundant construction and blind expansion of production capacity, protect the ecological environment, promote energy conservation and emission reduction, improve the utilization level of resources and energy, and formulate the “rock and wool industry standard according to relevant laws and regulations and industrial policies”. Entry conditions are now announced. Relevant departments and related enterprises should be based on the access conditions in the work of rock wool project investment, land supply, environmental assessment, energy supply, quality and safety supervision, credit, financing, construction and production operations.
