Description

technical field [0001] The invention relates to an ultrafine glass wool heat insulation board, in particular to a lightweight, uniform diameter ultrafine glass wool heat insulation board and a production method thereof. Background technique [0002] Ultra-fine glass wool heat insulation board is a new type of fibrous receptacle material. It has excellent properties such as light weight, heat preservation, fire prevention, sound absorption, moth resistance, and corrosion resistance. It is widely used in chemical industry, metallurgy, light industry, electric power, petroleum and achitechive. However, at present, the production methods used for ultra-fine glass wool on the market are very complicated, and the diameter deviation of the obtained glass wool is large, and the minimum diameter of the produced ultra-fine glass wool is also 3 μm to 5 μm. This will have a strong impact on the quality of glass wool and its glass wool products, limiting the development of glass wool pr...
