Abstract
The invention relates to a micropore ceramic filter element, in particular to a micropore ceramic filter element and a preparation method thereof. In the process of preparing the micropore ceramic filter element, raw materials are weighed according to the percentage in the formula, are added, mixed and uniformly stirred according to specified steps, and then are extruded or punched by an extruder or a punching machine into a blank, then the blank is dried at certain temperature to be shaped, and then the polyporous micropore ceramic filter element is formed. The micropore ceramic filter element is made of kaolin and diatomaceous earth which are bonded by a water-based adhesive, and has the advantages of low manufacturing cost, safety and environment protection. Simultaneously, the blank is molded by extrusion or punching, so cumbersome technology in the grouting process is eliminated, only moisture in the blank needs to be removed in the molding process, the existing energy-consuming process of long-time high-temperature calcination is avoided, and the production cost is greatly reduced.
Description
Skill this area
The present invention relates to a kind of candle, particularly relate to a kind of micropore ceramic filter element and preparation method thereof.
Background technology
At present, the preparation method of the ceramic element that purifying drinking water is used mainly is that kaolin, diatomite are through abrasive dust, add water pugging pulping, slurry is injected in the good mould of prepared beforehand makes idiosome, again the moisture in the idiosome is carried out drying, and then the idiosome of drying sent in the above high temperature furnace of 700 degree calcine moulding.This production technology not only production process is loaded down with trivial details, produce to drop into greatlyyer, and calcination process also is the process of a high energy consumption, causes the finished product production cost high always.
Summary of the invention
The present invention is in order to solve some loaded down with trivial details operating process and the expensive production cost that exists in the above-mentioned production process, a kind of new micropore ceramic filter element and preparation method thereof is provided, especially a kind of with water base adhesive as binding agent, method with extruding or punching press is made embryo fast, the moisture typing under cryogenic conditions in the oven dry idiosome.This micropore ceramic filter element production efficiency height, production cost is low, and the composition after the glue dries is silica, and composition is identical with diatomite or kaolinic composition, do not change the character of original ceramic element, simultaneously cheap, the safety of the cost of manufacture of water accack, environmental protection.
An object of the present invention is to provide a kind of micropore ceramic filter element.
Another object of the present invention provides the preparation method of described micropore ceramic filter element.
The objective of the invention is to be achieved through the following technical solutions:
A kind of preparation method of micropore ceramic filter element, it is formed by the feedstock production that comprises following mass percent;
