Abstract
The aim of the present invention is to manufacture a lithium-containing ferrous metal cleaner, which is characterized by composing a cleaner of an anionic surfactant of alkylbenzene sulfonic acid, a cleaner of an anionic surfactant of oleic acid triethanolamine salt, a cleaner of sodium carbonate, a cleaner of potassium hydroxide, a water softener of sodium silicate, a water softener of disodium edetate, a corrosion inhibitor of sodium nitrite, an defoamer of polyether, and pure water. The present invention is mainly suitable for washing ferrous metals prior to the processing, and is especially effective for cleaning oil traces and dust on ferrous metal surfaces. The appearance of the cleaner shows colorless or light yellow transparent liquid, the pH value is greater than 12, the cleaner has irritation for human skin, and protective gloves should be used during using the cleaner. The cleaner does not contain phosphorus, and does not produce overfertilization effects on aquatic environment.
Description
[technical field]
The invention reside in and make a kind of ferrous metal clean-out system that contains lithium, it is characterized in that being formed by clean-out system anion surfactant alkyl benzene sulphonate (ABS) lithium, clean-out system anion surfactant triethanol amine oleate, clean-out system yellow soda ash, clean-out system potassium hydroxide, water-softening agent water glass, water-softening agent disodium ethylene diamine tetraacetate, inhibiter Sodium Nitrite, defoamer polyethers, pure water.
[background technology]
Ferrous metal mainly refers to steel, the pig iron, iron alloy, cast iron etc.Pure iron and chromium are argenteous, and manganese is silver gray.Because steel surface covers the Z 250 of one deck black usually, and manganese and chromium are mainly used in the steel alloy of smelting black, so just can be called as ferrous metal.Because ferrous metal is before various complete processings, a large amount of dusts, oil stain and dirt can be adhered in its surface, so must clean.
[summary of the invention]
The object of the invention provides a kind of ferrous metal clean-out system that contains lithium, it is characterized in that being comprised of clean-out system anion surfactant alkyl benzene sulphonate (ABS) lithium, clean-out system anion surfactant triethanol amine oleate, clean-out system yellow soda ash, clean-out system potassium hydroxide, water-softening agent water glass, water-softening agent disodium ethylene diamine tetraacetate, inhibiter Sodium Nitrite, defoamer polyethers, pure water.
The present invention mainly is applicable to the cleaning before the ferrous metal processing, especially cleans very effective to the contained oil stain of ferrous metal surface, dust.
