Description
Technical field
The invention discloses a kind of preparation methods of ceramic foam filter film, belong to water-treatment technology field.
Background technology
Membrane technology is new and effective isolation technics, is become with its energy saving and environmental-friendly feature and solves global energy
One of general character support technology of the significant problems such as source, environment, water resource.Porous ceramic film, with its excellent stability of material,
The process industrials various fields such as oil and chemical industry, medicine, metallurgy have been widely used, it has also become film field is developed most
Rapidly, most one of membrane material of application prospect.
The separating property of porous ceramic film and the micro-structures such as the pore size of material and its distribution, porosity, pore morphology have
Close relationship.The aperture of porous ceramic film can carry out modulation in several nanometers to tens micron ranges.With porous pottery
Porcelain is compared, and porous ceramic film is unsymmetric structure, has higher separating property.The thickness of film is typically in the range of tens nanometers to several
Hundred microns can carry out the screening from nanoscale（If NF membrane is to the high rejection of multivalent ion）To visible bulky grain
Separation（Such as gas cleaning at high temperature）, have a wide range of applications field.The separating layer pore structure of porous ceramic film is particle with arbitrary
What accumulation mode was formed, porosity is usually 30~35%, and tortuosity regulation and control are more difficult, this causes ceramic film properties
It greatly improves and is limited to.Research ceramic membrane new preparation technology is that current ceramic membrane is led to improve its permeability and permselective property
One of the research emphasis in domain.How further to reduce the cost of ceramic film preparation be also ceramic membrane preparation research field emphasis it
One.And the problem of current porous ceramic film is also bad there are mechanical property, and service life is not long, therefore also need to carry out it
Further research.
Invention content
The present invention solves the technical problem of：For conventional porous ceramics film dynamic performance is bad, service life not
The problem of sufficient, provides a kind of preparation method of ceramic foam filter film.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
