Method for preparing ceramic water washing ball

Abstract

The present invention provides a method which is used for preparing a ceramic flush sphere and comprises the steps batching, molding and baking, and the method has the following characters: 20-92wt% powdered glass with granularity from 0.5 mu m to 300 mu m, 1-15wt% fluxing agent, 1-15wt% diborate, 5-20wt% ceramic powder and 1-30wt% pore forming agent are mixed with the proportion to prepare the uniform porous ceramic powder, then the porous ceramic powder is prepared to a flush sphere base substrate, after drying the base substrate is preserved in the temperature 600-1100 DEG C for 1-4 hours, and the ceramic flush sphere is prepared, wherein the ceramic flush is blending of one or any number of 0.5-5mu m granularity of quartz, coal gangue or mud sump. The invention adopts the powdered glass as the binding agent, the density is adjusted by the pore forming agent and the baking range is adjusted by fluxing agent, in the preparing process the powdered glass is melted in the high temperature condition to agglutinate the ceramic powder to a whole, meanwhile the gap generated by the high-temperature burning or volatilization of the pore forming agent is closed to form a closed hole, the density of the product is adjusted by the adding amount of the pore forming agent, the pore diameter of the product can be controlled between 0.1 and 0.5mm, and the inside and outside arrangement is uniform.

Description

technical field

[0001] The invention relates to a preparation method of ceramic washing balls, belonging to the technical field of porous ceramic preparation technology. Background technique

[0002] Washing balls are mainly used in the garment industry for grinding, washing and rinsing of materials and garments, such as denim fabrics, washed fabrics and their garments. At present, natural zeolite is mainly used, but because natural zeolite is soft and consumes a lot, it needs to be stopped at any time to replenish during use, which seriously affects the efficacy, and the zeolite waste residue is difficult to recycle, which is easy to cause environmental pollution. In response to the above problems, there have been technical reports on washing balls made of other materials, such as:

[0003] The plastic hollow rinsing ball involved in the Chinese patent ZL89108618 patent is not easy to wear, but the preparation cost is high, the process is complicated, and the color effect ...
