Abstract

The invention relates to an acid metal cleaner. The acid metal cleaner comprises the following components by weight percentage: 40% of hydrochloric acid, 5-10% of urotropin, 3-5% of sodium gluconate, 1-3% of oxalic acid, 2-3% of sodium dodecyl benzene sulfonate, 1-3% of AC1830 (N-Polyoxyethylated-N-octadecylamine), 1-3% of penetrant JFC, and the balance of water. According to the acid metal cleaner, rust stain, incrustation and oil stain of metal sections and equipment are effectively removed through the synergistic effect of acidic materials and surfactants, furthermore, the formula of the acid metal cleaner is simple, the acid metal cleaner can effectively lower the contamination degree, the cleaning period is long, and the production cost is lowered.

Description

A kind of acidic detergent for metal

Technical field

The invention belongs to the technical field of metal cleaning additive, relate to the Chemicals of clean metal surface rust stain, greasy dirt, especially a kind of acidic detergent for metal.

Background technology

Shape or equipment are owing to air, contacting and depositing under wet environment for a long time, surface very easily oxidized formation rust stain, and with water, contact and easily form incrustation scale, in process of metal working, can be infected with unavoidably in addition such as cutting wet goods greasy dirt, thereby cause the burn into of shape and equipment aging, reduce work-ing life,, need to clean shape for this reason.Traditional cleaning way is mainly strong acid and cleans, but strong acid is also very serious to the corrodibility of shape and equipment itself, and the poor effect of alkaline matter and surfactant washing, the cleaning interval is shorter, has improved production cost.

According to the retrieval, find the following patent documentation relevant to patent, particular content is as follows:

CN101165210 discloses a kind of acidic detergent for metal, it is characterized in that: this formulation weight per-cent is, phosphoric acid 5-7%, and butyl glycol ether 5-9%, alkoxylate straight chain alkanol 4-6%, surplus is water; The production technique of this formula is: under normal temperature, in the acid-resistant tank of 1.5 tons, first add a certain amount of water, in stirring, add a certain amount of phosphoric acid, add a certain amount of butyl glycol ether, add a certain amount of alkoxylate straight chain alkanol, the water that adds surplus mixes, then stirs 10 minutes, open valve canned, 5 kilograms every barrel.

CN101254412 discloses a kind of acidic hyperfiltration membrane cleaning agent, is comprised of permeate agent, redox agent and water, and the weight percentage of its composition is: permeate agent 15%～25%, redox agent 5%～20%, water 55%～80%.

CN1778881 discloses a kind of acidic cleaner, the raw material of following weight proportion, consists of: phosphoric acid 2-6 part, polyoxyethylene octylphenol ether 1-3 part, Citric Acid, usp, Anhydrous Powder 2-7 part, ketone 2-6 part, water 80-90 part.

CN101899667A discloses a kind of special cleaning agent for aluminium equipment, and it comprises the HNO of the raw material of following weight ratio: 15-25% ₃, the hydroxy ethylene diphosphonic acid of 3-10%, HF, the 0.5-1.5%JFC of 1-2%, the non-ionic polyacrylamide of 0.03-0.1%, the inhibiter L-5 of 0.1-0.5%, all the other are water.

By contrast, find, the application's composition is different from above-mentioned patent, and there is substantive difference in successful with above-mentioned patent.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art part, a kind of acid metal sanitising agent is provided, can effectively remove rust stain, incrustation scale and greasy dirt on shape and equipment.

The present invention realizes that the technical scheme of purpose is as follows:

A kind of acidic detergent for metal, comprise following component, and each composition weight percentage composition is respectively:

Hydrochloric acid 40-41%;

Urotropine 5-10%;

Gluconic acid is received 3-5%;

Oxalic acid 1-3%;

Sodium dodecylbenzene sulfonate 2-3%;

Stearylamine Soxylat A 25-7 1-3%;

Permeate agent 1-3%;

Add water to 100%.

And described permeate agent is JFC.

And the concentration of described hydrochloric acid is 35wt%-37wt%.

And described water is deionized water or pure water.

Advantage of the present invention and positively effect are:

Metal cleaner of the present invention is acid, to shape and the corrosion-free effect of equipment itself, and under acidic conditions, tensio-active agent in formula can make oily matter more easily and other separating substances, and acidic substance and tensio-active agent act synergistically, and can effectively remove rust stain, incrustation scale and the greasy dirt of shape and equipment, the present invention fills a prescription simply in addition, effectively reduce pollution level, and the cleaning interval is long, has reduced production cost.
