Problems solved by technology

[0002] Phosphorus-free degreasing agents currently on the market are mainly composed of strong alkali and a large amount of surfactants. Their main weaknesses are: the use temperature is high, reaching 80-90 ° C, and the degreasing time is long; there are many foams. Due to the large amount of surfactant used or improper selection, it is necessary to continuously add defoamers during use; it is not compatible with a variety of oils, which shows that the degreasing time of different oils may be long, short or even not within the process time. Degrease inside
Therefore, it is difficult to adapt to the requirements of low temperature, less foam, and removal of various high-quality oils in large-scale automated assembly lines

Abstract

The present invention relates to metal material detergent, and is especially one kind of industrial phosphate-free degreaser. The industrial phosphate-free degreaser consists of additive 0.1-10 wt%, sodium carbonate 35-65 wt%, anhydrous sodium metasilicate 20-50 wt% and octyl phenol polyethenoxy ether 0.5-5 wt%. The present invention has very powerful stain penetrating and emulsifying capacity, excellent effect of eliminating mineral oil and vegetable oil from metal surface, low treating temperature and fast oil eliminating speed, and is especially suitable for use in industry closed spraying and painting production line.

Description

technical field [0001] The invention relates to a metal material cleaning agent, in particular to an industrial phosphorus-free degreasing agent. Background technique [0002] Phosphorus-free degreasing agents currently on the market are mainly composed of strong alkali and a large amount of surfactants. Their main weaknesses are: the use temperature is high, reaching 80-90 ° C, and the degreasing time is long; there are many foams. Due to the large amount of surfactant used or improper selection, it is necessary to continuously add defoamers during use; it is not compatible with a variety of oils, which shows that the degreasing time of different oils may be long, short or even not within the process time. Degrease completely. Therefore, it is difficult to adapt to the requirements of low temperature, less foam, and removal of various oils and fats in large-scale automated assembly lines. Contents of the invention [0003] The technical problem to be solved by the prese...
