Waste ceramic produced environment friendly filter water stone n. and method for producing the same

Abstract

The invention relates to an environmental-friendly washing stone made from waste ceramics and a method for making the same. The washing stone comprises the following compositions in weight percentage: 70 to 85 percent of the waste ceramics, 3 to 8 percent of limestone, 10 to 20 percent of clay, 0.2 to 0.7 percent of additive, and 0.3 to 1.3 percent of combustion improver. The method for making the washing stone comprises the following steps sequentially: wet grinding; filtration; pressure filtration; first time of pugging; material bundling; vacuum pugging; edges and corners removal through arounding machine; drying; sintering; and surface layer removal through a grinding machine. The method combines the characteristics of a large amount of the waste ceramics in the prior industrial production and great demand for washing stone in garment industry, changes waste into valuable, has low production cost, and greatly improves comprehensive utilization degree of resources; besides, the produced washing stone has the advantages of light weight, even obturator foramen, certain hardness, good durability which is 8 times that of a natural vesuvianite, long service life, good stability, nosecondary pollution, great reduction of the import volume of the natural vesuvianite, and benefit to both the nation and the people.

Description

technical field [0001] The invention relates to a washing stone made of waste ceramics and a manufacturing method thereof. Background technique [0002] Garment processing and export is one of the main economic industries in my country. Guangdong Province is an important province for garment processing, production and export. Denim production and export account for about 50% of the national total. In the process of fabric production, a large amount of washing stones (also called pumice or natural volcanic stones) are needed for cleaning. Guangdong needs about 1 million tons of washing stones every year. At present, washing stones mainly rely on imports from Indonesia, Turkey and other places. Imported natural volcanic stone is not hard enough, and the silt waste produced during use also causes serious secondary pollution to the environment; at the same time, natural volcanic stone is easy to cause the dispersion of the color of the cloth and the waste residue to adhere to ...

AI Technical Summary

Problems solved by technology

Imported natural volcanic stone is not hard enough, and the silt waste produced during use also causes serious secondary pollution to the environment; at the same time, natural volcanic stone is easy to cause the dispersion of the color of the cloth and the waste residue to adhere to the surface of the cloth, which consumes water when washing Time-consuming, consumes a lot of water resources and electricity, high cost, and does not meet environmental protection requirements
