Abstract
The invention provides a formula and a production process method for a derusting cleaning liquid used for surface treatment of metal. The formula comprises a first formula and a second formula, wherein the first formula comprises the following components in percentage by weight: 17 to 22 percent of 35-percent hydrochloric acid, 2 to 4 percent of 36-percent acetic acid, 1.5 to 3 percent of glyoxal,0.5 to 1 percent of sodium chloride, 10 to 20 percent of water; and the second formula comprises the following components in percentage by weight: 17 to 22 percent of 35-percent hydrochloric acid, 13to 18 percent of 60-percent formic acid, 1.5 to 3 percent of glyoxal, 0.5 to 1 percent of sodium chloride, 10 to 20 percent of water. The production process comprises the following steps of: adding the glyoxal and the sodium chloride into the acetic acid and the water (or the formic acid and the water) respectively, and evenly stirring the mixing solutions to obtain two types of mixing solutions;and adding the hydrochloric acid into the two types of mixing solutions respectively, and evenly stirring to obtain the finished productions of two types of products. The formula has the advantages of strong derusting ability, high derusting speed, uniform and quick removal of rust and concrete on steel and copper materials, safe and convenient production and use, and low cost.
Description
One, technical field:
The present invention relates to the prescription and the method for manufacturing technology of the derusting cleaning liquid that a kind of metal finishing uses, the prescription and the production technique thereof of the quick derusting cleaning liquid that particularly a kind of safety in utilization is good
Two, technical background:
Studies show that steel derusting rust-preventive agent technology can be divided into multiple classification such as derusting cleaning liquid, phosphatization passivation rust protection liquid, multifunctional derusting rust protection liquid, the multi-functional treatment solution of very low temperature derusting rust-proofing, high pasty state rust-removing and-preventing agent, solid rust remover.But it is main be equipped with formulated mix acid liquors such as phosphoric acid, acetic acid again and have stronger corrodibility that they overwhelming majority is to use strong acid such as sulfuric acid, hydrochloric acid, nitric acid, not only corrodes the skin injury clothing and uses dangerous but also pollute the environment.For example the Chinese patent notification number is that the patent application of CN8810409A, CN1055961A all is so, and improved necessity is arranged.
Three, summary of the invention:
The objective of the invention is to invent and a kind ofly replace strong acid and add the quick derusting cleaning liquid safe in utilization that can overcome the background technology shortcoming that additive is formed with weak acid.Technical scheme of the present invention is: adding acetic acid or hydrochloric acid adds two kinds of mix acid liquors of formic acid with hydrochloric acid, is two kinds of products that additive constitutes with oxalic dialdehyde and sodium-chlor.
The formula table of derusting cleaning liquid safely and fast of the present invention is as follows: (weight %)
| Starting material | Specification | Formula range | Embodiment 1 | Embodiment 2 |
| Hydrochloric acid | ??35％ | ??17-22 | ?20 | ?20 |
| Acetic acid | ??36％ | ??2-4 | ?3 | ?- |
| Formic acid | ??60％ | ??13-18 | ?- | ?15 |
| Oxalic dialdehyde | ??40％ | ??1.5-3 | ?2 | ?2 |
| Sodium-chlor | Technical grade | ??0.5-1 | ?1 | ?1 |
| Water | Tap water | ??10-20 | ?11 | ?11 |
Scavenging solution preparation lime light of the present invention has:
The oxalic dialdehyde consumption must be in the routine scope of table, and efficient is too low very little, and too many viscosity height is uneconomical.Sodium-chlor is that the most cheap wetting catalysis stripper has quickened dirty the peeling off of rust.
Processing sequence of the present invention is:
Embodiment 1: by formula ratio earlier with oxalic dialdehyde, sodium-chlor, acetic acid and water adds and adds hydrochloric acid after mixing in the reactor again and mix and get product.
Embodiment 2: by formula ratio earlier with oxalic dialdehyde, sodium-chlor, formic acid and water adds and adds hydrochloric acid after mixing in the reactor again and mix and get product.
Advantage of the present invention:
1, the rust cleaning power speed that eliminates rust by force all is suitable for the rust thing on iron and steel and copper surface soon;
2, good to concrete solvability, accompanying removal such as the steel framework that concrete placement is used and template is easy;
3, not injured skin safe in utilization and clothing;
4, the simple preparation of prescription is easy to use cheap easily.
Four, embodiment;
Embodiments of the invention 1 are identical with the routine consumption of table with embodiment 2 prescriptions, and used technology is identical with the explanation of embodiment 2 in last routine embodiment 1.
Claims (2)
1, the prescription of the derusting cleaning liquid used of a kind of metal finishing and prescription that method of manufacturing technology is characterized in that it are composed as follows: (weight %)
The acetic acid 2-4 oxalic dialdehyde 1.5-3 sodium-chlor 0.5-1 water 10-20 of the hydrochloric acid 17-22 36% of prescription 1:35%
The formic acid 13-18 oxalic dialdehyde 1.5-3 sodium-chlor 0.5-1 water 10-20 of the hydrochloric acid 17-22 60% of prescription 2:35%.
2, the prescription and the method for manufacturing technology of the derusting cleaning liquid of using according to a kind of metal finishing of claim 1 is characterized in that:
Process for making is: earlier with oxalic dialdehyde, sodium-chlor adds and makes two kinds of mixed solutions after stirring behind acetic acid and the water (or formic acid and water), again hydrochloric acid is added two kinds of mixed solutions afterwards respectively and stirs and can obtain the finished product of two kinds of products of the present invention afterwards.
