Abstract

The invention relates to the technical field of research, development and manufacturing of basalt fibre, and discloses modified basalt fibre applied to water quality purification. The modified basalt fibre is prepared by adding 3 to 5 mass percent of a composite material and adopting a film pressing and forming technology on the basis of an original basalt stone material, so that the problems of low efficiency, high cost, complicated operation, difficulties in treating low-concentration metals and bacterial pollutants in the existing water quality purification treatment are solved; the modified basalt fibre has a good removal effect on low-concentration metal ions, organic matters and bacteria in water through physical-chemical adsorption; the treated water quality meets GB 5749-85 drinking water standards; the removal rate reaches 99.9 percent; therefore, the modified basalt fibre has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of R&D and production of basalt fibers, and in particular relates to a modified basalt fiber used in water purification. Background technique [0002] Basalt fiber is a continuous fiber drawn at high speed by platinum-rhodium alloy drawing bushing after basalt rock is melted at 1450°C-1500°C, similar to glass fiber, its performance is between high-strength S glass fiber and alkali-free E glass Among the fibers, the color of pure natural basalt fibers is generally brown, and some are golden. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of basalt rocks composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, iron oxide and titanium dioxide. drawn. Basalt continuous fiber not only has good stability, but also has various excellent properties such as electrical insulation, corrosion resistance, combustion resistance, an...
