The present invention is suitable for dust removal and filtration field of material technology, a kind of preparation method of superfine modified glass fiber filter material of fluorine silicon oxygen is provided, solve in the prior art that glass fibre toughness is poor, temperature tolerance, wear-resisting folding resistance, and the technical problem poor to the antioxygen property of sulfur dioxide and other pernicious gases, the preparation method is the following steps are included: acid dip, washing, drying, potassium permanganate oxidation processing, thermal cleaning, chemical size dipping, drying finished product.The properties of product of preparation method production of the present invention are excellent, chemical stability is good, resistance to temperature has been increased to 600 DEG C or more from 280 DEG C or so of bare glass fibre filtering material, high-strength low-ductility, wear-resisting, folding and antiacid alkali, corrosion resistance are prominent, glass fiber material obtained is widely used in the industries such as steel, smelting, cement, coal-burning boiler, carbon black, electric power, the dust collection rate of the superfine modified fiber filter material of fluorine silicon oxygen can reach 99.99%, dust emission 5-20mg/Nm hereinafter, at home, development abroad prospect is very wide and huge market potential. |
