【発明の名称】ミクロ濾過用セラミツク膜の製造方法
Document Type and Number:
Japanese Patent JP2751989
Kind Code:
B2
Abstract:
In the manufacture of a ceramic membrane for micro-filtration having a porous ceramic carrier and a ceramic micro-filtration coating on a bulk surface of said carrier, the steps are performed of (i) silanising said carrier at least at said bulk surface thereof, (ii) after step (i), applying a coating film containing metal oxide to said bulk surface of said carrier by contacting a stable suspension of non-agglomerated metal oxide particles with said bulk surface and moving said suspension along said bulk surface, so that said coating film remains adhering to said bulk surface, and (iii) drying and heating said carrier and said coating film thereon, so as to sinter at least said coating film and thereby form said micro-filtration coating on said carrier. In order to improve the uniformity and evenness of the coating film of the suspension, the stable suspension contains an organic additive which increases the yield stress of the stable suspension to a value greater than zero. The organic additive is one which is capable of giving said stable suspension a yield stress of at least 0.1 Pa at a concentration of not more than 5% by weight of the liquid component of the suspension without causing agglomeration of the particles.
