Abstract
The invention relates to a rust remover for ferrous metals, which is characterized by comprising a cleaning agent nonionic surfactant, a defoaming lubricant, a rust remover, a corrosion inhibitor and purified water. The rust remover disclosed by the invention has the function of rapidly removing the rust on the surfaces of the ferrous metals and has very good moistening, decontaminating and deoiling effects before rust removing. According to the invention, the rust remover is colourless or yellowish transparent liquid and has acid corrosivity; the pH (potential of Hydrogen) value is less than 1; and the labor protection is needed during the process operation. When the rust remover disclosed by the invention is in use, the acid removing temperature is controlled between 30 DEG C and 40 DEG C and the acting time is 10-15 minutes.
Description
[technical field]
The invention reside in and make a kind of ferrous metal rust remover, it is characterized in that by a kind of ferrous metal rust remover, it is characterized in that being formed by clean-out system nonionogenic tenside, froth breaking lubricant, rust remover, inhibiter and 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.When ferrous metal was longer in the shelf-time, its surface can generate oxide compound because of oxidation, and dust, oil stain and dirt, so first being processed must be carried out decontamination, cleaning and acidifying.The purpose of acidifying is to remove Z 250 ferrous metal surface, black.
[summary of the invention]
The object of the invention provides a kind of ferrous metal rust remover, it is characterized in that by a kind of ferrous metal rust remover, it is characterized in that being comprised of clean-out system nonionogenic tenside, froth breaking lubricant, rust remover, inhibiter and pure water.
The present invention has the function of quick removal ferrous metal surface rusty stain, the effect of before rust cleaning well wetting, decontamination is arranged, deoiling.
Outward appearance of the present invention is colourless or light yellow transparent liquid, pH value＜1, when acid corrosion, technological operation are arranged labour protection must be arranged.
The present invention's temperature that deacidifies is controlled between 30-40 ℃ 10-15 minute action time.
The present invention it is characterized in that by wetting clean-out system nonionogenic tenside polyoxyethylene nonylphenol ether (E0=10) 0.3-0.6%, wetting clean-out system nonionogenic tenside castor oil polyoxyethylene ether (E0=15) 0.3-0.9%, wetting defoamer nonionic polyoxyalkylene surface active agent-F68 0.3-0.6%, rust remover hydrochloric acid (content 36%) 20-40%, rust remover sulfuric acid (content 37%) 20-40%, inhibiter di-o-tolyl-thiourea 0.3-0.6%, inhibiter vulkacit H 0.3-0.6% and pure water 30-40% form.
Making method of the present invention is: be metered into pure water in confined reaction is filled with, stir, be metered into successively more wetting clean-out system nonionogenic tenside polyoxyethylene nonylphenol ether (E0=10), wetting clean-out system nonionogenic tenside castor oil polyoxyethylene ether (E0=15) and wetting defoamer nonionic polyoxyalkylene surface active agent, slowly add in the pure water, stir; Continue metering and slowly add rust remover hydrochloric acid (content 36%), rust remover sulfuric acid (content 37%), inhibiter di-o-tolyl-thiourea and inhibiter vulkacit H, slowly stir after 30-40 minute, measure Specifications, the qualified rear filtration packing of packing into.
