Abstract
This utility model provides a kind of composite ceramic film, described composite ceramic film includes the supporter with fluid passage, farther including: enhancement Layer, described enhancement Layer is enclosed within the outside of described supporter, and is formed with per-meate side passage between described enhancement Layer and supporter.This utility model has the advantages such as the high and low cost of intensity.
Description
Technical field
This utility model relates to ceramic membrane, particularly to a kind of composite ceramic film.
Background technology
Ceramic membrane is acidproof, alkaline-resisting, organic solvent-resistant, and mechanical strength is big, can back flush, anti-microbe ability is strong, high temperature resistant, separation efficiency high, in food industry, biological engineering, environmental project, chemical industry, petrochemical industry, control the fields such as metal working industry and be widely used.
In Multichannel ceramic membrane supporter preparation process, radially on section, thickness is different everywhere, and during extrusion molding, stress can not be completely uniform everywhere, and the green compact obtained density everywhere has difference.In sintering process, when temperature is higher than uniform temperature, supporter can be in flow regime, produces viscous flow, promotes relative movement between solid particle, formed tightly packed, thus cause volume contraction and densification.It is affected by gravity simultaneously, supporter will necessarily be caused in extrusion, be dried and sintering process deforms, cause between adjacency channel and supporting layer in uneven thickness between outermost passage and supporter outer rim.
Therefore, being affected by manufacturing process, between the middle adjacency channel of ceramic membrane finished product, thickness and each passage of outer layer of the thinnest part of supporting layer all cannot be ensured of identical with the thickness of supporter outer rim supporting layer.Between middle adjacent each passage, the use of ceramic membrane typically will not be impacted by supporting layer uneven thickness, because in ceramic membrane system work running, each vias inner walls stress on same radial direction interface is essentially identical, supporting layer all directions stress is offset, and does not results in supporting layer between each access opening and damages.Supporting layer between passage each for outermost layer and supporter perimeter wall is the most different, the operating pressure of the outer material of supporter is less than the pressure of material in each passage, that is in ceramic membrane running, outermost layer passage is stress near the supporting layer of supporter outer rim, and its Impact direction is along passage radially.If outermost layer passage is different with perimeter wall supporting layer thickness, just certainly exist a place the weakest, during ceramic membrane uses, be easier to rupture.
In the application, either import or domestic ceramic membrane, the most repeatedly there is the supporter localized delamination between ceramic membrane outermost passage and supporter outer rim, cause that product water is defective, system-down, impact produces properly functioning.
Summary of the invention
In order to solve the deficiency in above-mentioned prior art, this utility model provides the composite ceramic film of the high and low cost of a kind of intensity.
The purpose of this utility model is achieved through the following technical solutions:
A kind of composite ceramic film, described composite ceramic film includes having the supporter of fluid passage and be coated in the membrance separation layer on top layer, fluid passage, and described composite ceramic film farther includes:
