Abstract

The invention discloses efficient low-foam normal-temperature phosphorous-free oil removing liquid. The oil removing liquid consists of the following components in percentage by weight: 3.0-7.0 wt% of alkylphenol polyoxyethylene ether, 1.0-5.0 wt% of fatty alcohol polyoxyethylene ether, 1.0-5.0 wt% of fatty acid methyl ester polyoxyethylene ether sulfonate, 0.5-4.0 wt% of linear alkylbenzene sulfonate, 10.0-30.0 wt% of carbonate, 4.0-15.0 wt% of sodium metasilicate pentahydrate, 5.0-15.0 wt% of sodium hydroxide, 4.0-12.0 wt% of sodium citrate, 0.5-1.0 wt% of redeposition resisting agent, 2.0-5.0 wt% of complexing agent, 0.1-0.3 wt% of defoaming agent, 1.0-3.0 wt% of corrosion inhibitor, 0.01-0.1 wt% of flocculating settling agent, and the balance of water. The oil removing liquid has the characteristics of cost saving, improvement of oil removing efficiency and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of iron and steel degreasing and cleaning. In particular, it relates to a high-efficiency, low-foaming, normal-temperature, phosphorus-free degreasing fluid. Background technique [0002] The degreasing treatment before electroplating and coating of steel parts is one of the key processes to ensure the bonding force of the plating (coating) layer. If there is an "interlayer" of organic substances such as oil stains on the metal surface during the treatment process, it will affect the flatness, bonding force, corrosion resistance, etc. of the plating (coating) layer, and even lead to discontinuous and loose deposition, and even The layer peels off, making it lose its actual use value. [0003] Degreasing fluids are complex mixtures of organic and inorganic chemicals in a water base. The degreasing liquid uses the saponification effect of alkali on oil stains and the emulsification effect of surfactants to ...
