Develop the great realistic meaning of adsorbent of other forms.In recent years, the research about functional fiber sorbing material is increasingly becoming
Adsorbent research hot spot, study at present more functional fiber sorbing material mainly active Carbon fibe, cellulose fibre,
Chitin fiber and surface modified fibre etc..
Basalt fibre is the wire drawing after 1500 DEG C or so high-temperature fusions and the company that is formed using natural basalt as raw material
Continuous fiber.It has the excellent properties such as high-strength light, high temperature resistant, corrosion-resistant, anti-oxidant, radiation protection, wide in numerous areas purposes
It is general.In materialogy field, basalt fibre is usually as a kind of reinforcing material, in enhancing concrete, asphalt, You Jigao
Superior effect is shown in the application of the materials such as molecule.
Using the functional fibers such as cellulose acetate, PVA, polyacrylonitrile, chitosan sorbing material as moulding material, the Black Warrior
Rock fiber is as reinforcing material, and by industrial residue, zeolite etc., composite fibre material is prepared into using certain technological means and method
Material can either make industrial residue obtain the recycling of high added value for dirty (useless) water dephosphorization, while can greatly improve dephosphorization effect
Fruit.
Suitable sewage disposal is successfully compounded out currently with industrial residue, zeolite, basalt fibre and the moulding material
The high efficiency composition threadiness dephosphorization material that technique uses, and dirty (useless) water process and regulating water environment are used for this and realize that phosphorus provides
The recycling in source, domestic there is not been reported.
