Problems solved by technology

For these white clays containing 20-30% oil, some manufacturers will carry out secondary deep pressing to obtain mixed oil and waste white clay containing 5-8% oil. If you want to get oil from this waste white clay, the cost will be high , so manufacturers will treat it as waste. Due to the high processing cost, most of the oily waste soil in oil factories will be piled up or buried, which will cause environmental pollution, waste resources, and affect the sustainable development of resources and the environment.

Abstract

The invention relates to an environment-friendly metal cleaning agent comprising organic surfactants and water; especially, the environment-friendly metal cleaning agent also comprises, by weight, 10%-25% of modified waste clay which is prepared through activation treatment of waste clay containing grease and esterification reaction to glucose. The environment-friendly metal cleaning agent provided by the invention has good cleaning effect on oil stain and carbon soot, and the raw materials used in the invention are all environment-friendly and degradable, and will not result in environmental pollution, body injury or metal surface corrosion; in addition, the environment-friendly metal cleaning agent provided by the invention is prepared by using the waste clay originally discarded as the raw materials, recycling of resources can be achieved, and at the same time the production cost of the cleaning agent is reduced.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to an environment-friendly cleaning agent for cleaning mineral oil, carbon dust and oxide impurities on the surface of various metal parts. Background technique [0002] In industrial production, whether it is the processing and assembly of parts, or heat treatment and electroplating, the metal surface must be cleaned; large mechanical workpieces such as vehicles and ships are prone to oil and dust. In order to improve the adhesion and corrosion resistance of coatings, coating The metal surface must be degreased and degreased before installation. The grease attached to the metal surface includes various acids, alkalis, dust, cutting, hand sweat, oil stains, etc. The existence of these dirts not only affects the smooth progress of various processing procedures such as metal plating and coating, but also causes and accelerates Metal corrosion reduces product quality and shortens service life. At ...
