Abstract

The invention provides a manufacturing method of water-purifying porous ceramic. The water-purifying porous ceramic comprises the following components in percentage by mass: 60 to 80 percent of diatomite, 0 to 5 percent of limestone, 0 to 13 percent of kaolin, 0 to 12 percent of Datong soil, 0 to 10 percent of quartz, 0 to 20 percent of aluminum oxide, 0 to 5 percent of lithium chinastone and 0 to10 percent of dolomite. The water-purifying porous ceramic adopts a dry ball-milling, balling, heating and firing process; the prepared water-purifying porous ceramic has high chemical stability, high porosity, high permeability, high strength, high rigidity, high heat stability, good self-cleaning state, small volume density, high reproducibility, long service life and high antibacterial property, is not liable to be degraded by bacteria and is suitable for water filtration.

Description

technical field [0001] The invention relates to the technical field of water-purifying ceramics, in particular to a method for manufacturing water-purifying ceramics. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the quality of domestic water. Due to some problems in my country's traditional water supply technology and water supply network itself, the water quality of urban and rural tap water has been improved slowly, and it is difficult to meet people's expectations. Therefore, some residents have installed water purification devices at the water supply terminals at home. At present, the price of many water purifiers is relatively expensive, which limits the promotion and use of water purifiers. Therefore, the development of an economical, simple and safe household water purifier is helpful for improving the sanitary level of drinking water for urban and rural residents. very necessary. Th...
