By using above-mentioned technical proposal, in a tubular form and both ends open by novel super nano ceramics film, filter sewage
When, will novel super nano ceramics film one end block after from open end inject sewage, by the water purification after micro porous filtration from novel
The tube wall exudation of super nano ceramics film is that 50-60nm makes in sewage by micropore size to complete sewage water filtration purification
Most harmful substances can not be completely cut off by the tube wall of novel super nano ceramics film in novel super nano ceramics film
In pipe shaft, so that filter effect is preferable；By the way that starch is added using as thickener, when increasing the film preparation of novel super nano ceramics
The consistency of slurry condition reduces mobility, and then is easy to embryo processed, and idiosome is made to be not easy deformation, and stability is preferable；High temperature is burnt
When knot, starch carbonizing is to form a large amount of carbons and then generate carbon with the silicon dioxde reaction in fumed silica and zircon
SiClx, so that the structural strength of novel super nano ceramics film is preferable；By the way that fumed silica is added using as thixotroping
Agent so that improving the mobility of mud when wearing into mud, and generates hydrogen bond by fumed silica after embryo processed to be formed
Network structure forms constraint in turn, so that idiosome is unlikely to deform, further increases the stability of idiosome.
The present invention is further arranged to: the preparation method of the novel super nano ceramics film the following steps are included:
(1) slurrying, specific as follows:
By kaolin, feldspar, zircon, starch, fumed silica, black mud, dolomite, thickener, water-reducing agent and water
It is added in ball mill and is milled into mud；
(2) slurry dewatering, specific as follows:
By filters pressing moisture is discharged to form filter residue；
(3) embryo processed, specific as follows:
Filter residue is put into compression moulding in mold to form the raw embryo of tubulose；
(4) dry idiosome, specific as follows:
Natural air drying forms dry embryo after raw embryo demoulding；
(5) dry embryo Tu Fu You slurry；
(6) fiber is planted, specific as follows:
The polyacrylonitrile fibre that diameter is 40-50nm is radially planted on dry embryo along dry embryo, the polyacrylonitrile fibre
Length is greater than the pipe thickness of dry embryo, the polyacrylonitrile fibre through dry embryo tube wall and both ends stretch out the tube wall of dry embryo
Outside；
(7) it is sintered, specific as follows:
It is sintered by electric arc furnaces, 2800-3000 DEG C of sintering temperature.
By using above-mentioned technical proposal, by polyacrylonitrile fibre being planted on the tube wall of dry embryo to pass through in calcining
High temperature thermally decomposes polyacrylonitrile fibre, so that dry indusium polyacrylonitrile fibre through part forms micropore, so that
The novel super nano ceramics film that sintering is formed forms micropore, since the diameter of polyacrylonitrile fibre is 40-50nm, in polypropylene
Nitrile fiber can generate portion gas when thermally decomposing, will so that on dry embryo by the perforative micropore of polyacrylonitrile fibre by gas strut with
Reaming is stretched out due to polyacrylonitrile fibre both ends outside the tube wall of dry embryo, ensure that the micropore and the external world on the tube wall of dry embryo connect
It is logical, so that the gas that polyacrylonitrile is decomposed and generated can smoothly be discharged along micropore, so that reaming effect is lower, avoid
The case where reaming excessively causes micropore size to increase, so that sintered novel super nano ceramics film forms the micro- of 50-60nm
Hole, far below the micropore size that common nano ceramics film 100nm is acted on, so that the filtering of novel super nano ceramics film is dirty
The effect of water is preferable；By on dry embryo plant polyacrylonitrile fibre with utilize dry embryo with certain structural strength characteristic,
It avoids causing idiosome to crumble when plantation；By the thixotropy of fumed silica, so that the stabilization constrained by fumed silica
Molding dry embryo, because of external force, has interrupted the hydrogen of fumed silica when polyacrylonitrile fibre runs through the tube wall of dry embryo
Key so that the decline of local restriction power even disappears so that dry embryo had both been able to maintain good shape stability, at the same be easy to by
Polyacrylonitrile fibre runs through, easy for construction；It is sintered by electric arc furnaces so that the carbon formed after starch carbonizing restores zircon
In zirconium dioxide form zirconium carbide, and carbon and the silica in fumed silica and zircon are anti-at high temperature
Silicon carbide should be formed, so that the high temperature resistance and physical property of novel super nano ceramics film greatly improve；Pass through starch
It is carbonized and starch is used as thickener before sintering and provides carbon in sintering to form carbon, make full use of original
Material reduces cost while reducing impurity to reduce additive.
The present invention is further arranged to: in the step (2), filter residue moisture content is 30-33%.
By using above-mentioned technical proposal, enabling has preferable structural stability when filter residue compression moulding, reduce because
Situations such as filter residue water content causes greatly very much raw embryo to be collapsed, deformation, while guaranteeing enough moisture content so that filter residue is easy to moulding,
Convenient for construction.
The present invention is further arranged to: natural air drying 24-48 hours in the cool in the step (4).
By using above-mentioned technical proposal, by natural air drying to further increase green structure intensity, while passing through foot
The enough long time is so that each raw material directly preferably combines, and avoids high temperature drying that dry embryo is caused to harden and then influence subsequent
The case where planting fiber.
The present invention is further arranged to: in the step (6), polyacrylonitrile fibre length is the pipe wall thickness of dry embryo
120%.
By using above-mentioned technical proposal, guarantee the tube wall that polypropylene fibre has enough length to stretch out dry embryo with both ends
Outside.
The present invention is further arranged to: in the step (6), driving polyacrylonitrile fibre through dry by high-voltage electrostatic field
The tube wall of embryo.
By using above-mentioned technical proposal, so that plantation fiber operation is convenient, high-efficient, verticality is higher when plantation, matter
Amount is preferable.
The present invention is further arranged to: in the step (6), positive pole pipe being axially inserted into dry embryo along dry embryo, will be adhered to
There is the cathode tube of polyacrylonitrile fibre along dry plumular axis to covering outside dry embryo, electrostatic field is generated so that polyacrylonitrile fibre by high pressure
It circles in the air with negative electrical charge and towards positive pole pipe and then through dry embryo.
By using above-mentioned technical proposal, cooperated by positive pole pipe and cathode tube to reduce the case where losing dry embryo, and
So that electrostatic field distance is shorter, electrostatic adsorption force is larger, so that the acceleration that polyacrylonitrile fibre is generated by electrostatic field
It is larger, to guarantee that polyacrylonitrile fibre runs through the effect of dry embryonic tube wall with stronger penetration power.
In conclusion the invention has the following advantages:
1. being that 50-60nm makes most harmful substances in sewage that can not receive by novel super by micropore size
The tube wall of rice ceramic membrane is to completely cut off in the pipe shaft of novel super nano ceramics film, so that filter effect is preferable；
2. by the way that starch is added so that as thickener, slurry condition is thick when increasing the film preparation of novel super nano ceramics
Degree, and then is easy to embryo processed, when high temperature sintering, starch carbonizing with formed a large amount of carbons so that with fumed silica and zircon
In silicon dioxde reaction generate silicon carbide so that the structural strength of novel super nano ceramics film is preferable；
3. being sintered by electric arc furnaces so that the zirconium dioxide in the carbon reduction zircon formed after starch carbonizing is formed
Zirconium carbide, and the silicon dioxde reaction in carbon and fumed silica and zircon forms silicon carbide at high temperature, makes
The high temperature resistance and physical property for obtaining novel super nano ceramics film greatly improve.
