A normal temperature degreasing powder

Abstract

The invention discloses a normal-temperature oil removal powder. The normal-temperature oil removal powder comprises, by weight, 20-60 parts of sodium hydroxide, 5-20 parts of sodium metasilicate pentahydrate, 5-25 parts of sodium gluconate, 10-30 parts of sodium citrate, 1-5 parts of a nonionic emulsifier composition and 2-3 parts of a low molecular defoamer. The oil removal powder can be used toremove oil without heating, so alkali mist is prevented, the neat environment of a production workshop is ensured, and environmental pollution is avoided; an oil removal liquid does not need to be heated, so a lot of electric power can be saved, the energy loss is reduced, the oil removal efficiency is high, damages to a substrate are avoided, and the oil removal liquid has a long stay time; andthe oil removal powder contains no phosphorus, can be easily biodegraded, and avoids the problem of rich oxidation.

Description

technical field

[0001] The invention relates to the technical field of cleaning agents, in particular to a normal temperature degreasing powder. Background technique

[0002] Degreasing powder is a chemical widely used in the pretreatment of hardware, plastic electroplating, and spraying industries, commonly known as degreasing powder. It is also used in various hardware cleaning industries, and can be divided into chemical degreasing powder and electrolytic degreasing powder according to the cleaning method. Degreasing powder is a low-foaming degreasing and degreasing agent refined from a variety of high-quality surfactants, detergents, penetrants, builders, etc. It has good wetting and emulsifying capabilities, and has strong degreasing properties. ability. There is no visible oil film or oil spots on the surface of the workpiece after cleaning. It can be applied to cleaning various materials such as aluminum alloy, zinc alloy, magnesium alloy, steel parts, stainless st...
