Abstract

The invention discloses a method for producing a gas adsorption material by tea wastes. The method comprises the steps of removing wax, cleaning, drying, crushing, adding an assistant, performing heat evaporation, pressing and molding and stoving, so that the novel molding material based on the tea wastes can be prepared. The tea wastes are treated ideally; the waste is changed into treasure; and the prepared novel molding material is higher in accumulation density, large in adsorption capability under unit volume and good in adsorption effect; and long-time adsorption for toxic gas and peculiar smell can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gas adsorption materials, in particular to a method for producing novel adsorption materials by using tea waste. Background technique [0002] Tea drinking culture has a long history in China and is the national drink of the Chinese nation. Chinese tea culture is a combination of Chinese Confucianism, Taoism, and Buddhism. It is a unique flower in Chinese culture. It is fragrant and mellow. Chinese people cannot do without tea in their daily life. China's annual tea production reaches 100 More than 10,000 tons, China's tea production and consumption has become "the first in the world". Especially in recent years, tea beverage enterprises have produced a large amount of tea dregs, and there is an urgent need for a new technology to deal with these tea wastes, so as to turn waste into protection. [0003] Studies have shown that tea is a porous substance with a highly developed pore structure. The por...
