Rock wool product is a kind of mineral wool made of molten natural igneous rock, with basalt as the main component, plus an appropriate amount of auxiliary materials, artificial inorganic fibers made by high temperature melting and centrifugal blowing. It has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. Rock wool products are suitable for industrial equipment, construction, ship insulation, sound insulation, etc., and are divided into marine, hydrophobic, and architectural rock wool insulation boards.
The acidity coefficient of rock wool
The acidity coefficient is an index value to measure the chemical durability of rock wool, which is the mass ratio of the sum of silica and alumina to the sum of calcium oxide and magnesium oxide in the fiber composition. The acidity coefficient is an important indicator for evaluating the quality of rock wool products. High acidity coefficient, good weather resistance and long service life. At the same time, the acidity coefficient is also an important means to distinguish between rock wool and slag wool. The raw material of slag wool is mainly slag, the acidity coefficient is less than 1.5, and the raw material of rock wool is mainly basalt, and the acidity coefficient is ≥1.6.
Building energy efficiency, originally aimed at reducing energy consumption in buildings, now means more rational and efficient use of building energy and continuous improvement of energy efficiency. Building energy conservation specifically refers to the implementation of energy conservation standards in the planning, design, new construction (renovation, expansion), transformation and use of buildings, and the use of energy-saving technologies, processes, equipment, materials and products to improve thermal engineering and improve the thermal insulation of heating, air conditioning, and cooling and heating systems. performance and efficiency, strengthen the operation and management of building energy systems, utilize renewable energy, and reduce heating, air conditioning, heating, lighting, and hot water supply on the premise of ensuring the quality of energy consumption in the indoor thermal environment.
At present, the average fiber diameter of my country's rock wool industry is mainly 4μm ~ 6μm. The smaller the diameter of a single fiber, the higher the fiber strength. The fiber diameter level of Uetersen glass wool can not only ensure the strength performance, but also meet the environmental protection requirements, and the fiber quality is good, which is welcomed by the market.
