Abstract
The invention discloses a kind of environmentally friendly fast acids for removing metal material oxide layer to clean lotion BW 500P and regenerated additive BS 51.Detergent is mainly by alcohol 1% 30%, tartaric acid 1% 20%, 1% 30% composition of polyethylene glycol 1% 30, AEO 9 1% 10%, dodecyl sodium sulfate 1% 10%, modified cellulose 1% 10%, tannic acid 1% 20%, benzotriazole 0.5% 10%, phytic acid.Regenerated additive BS 51 is mainly made of malonic acid 5% 30%, potassium ferrocyanide 10% 50%, acrylic acid 1% 20%, ammonium hydroxide 10% 40%.By physical agitation and chemical reactive synthesis.The invention solves various problems existing for strong acid pickling derusting from technological angle：Acid gas pollutes, inorganic salts pollution etc..Steel and iron parts pickling is very suitable for, cost is very low, may be reused after adding in 51 regenerated additives of BS.The invention can be applied to the acid cleaning process of each metalloid material, such as copper material, aluminium, steel.
Description
Technical field
The present invention is quick by a kind of environmental protection that the strong acid such as hydrochloric acid, sulfuric acid, nitric acid is replaced to remove metal material surface oxide layer
Pickling technology is related to fast acid and cleans lotion and anti-aging regenerated additive.It is suitable for various metal material surface pre-treatments
When oxide layer removing.It is discharged with no acid gas, production cost is low, waste water is disposable, non-hazardous to subsequent handling etc. many excellent
Point.
Background technology
At present, the metal materials such as steel copper generally carry out immersion derusting using hydrochloric acid, sulfuric acid, nitric acid, give up in production process
Gas, waste water cause severe environmental pollution, while hydrochloric acid sulfuric acid is easy toxogen material processed, is stringent management and control substance.Many units use
The weaker derusting such as phosphoric acid or oxide layer, but processing speed is slow, efficiency is low, and also cost is very high, and enterprise is badly in need of a kind of new
Type ring protects oxide layer technique and solves acid gas pollution, substitutes traditional derusting process.
The content of the invention
The present invention is that a kind of environmentally friendly fast acid cleans lotion and regenerated additive, which adds in phosphoric acid, improves
The reaction speed and peeling rate of phosphoric acid and oxide layer, and inhibition is carried out to metal material, acid consumption is reduced, and can be to acid
Liquid carries out regeneration treatment.The present invention solves the problems, such as follows：1. substituting strong acid, solves acid gas pollution.2. reduce Metal Substrate
Body corrodes.3. improving phosphoric acid pickling efficiency, and production cost is greatly lowered.4. the sewage-sludge quantity of slag is than strong acid pickling and single
Phosphoric acid pickling significantly declines.5. pickle ageing time greatly prolongs.6. the pickle after aging can regenerate.
The technical formula that the present invention uses is：
a：BW500P is formulated
| Material name | Addition % |
| Alcohol | 1-30 |
| Tartaric acid | 1-20 |
| Polyethylene glycol | 1-30 |
| AEO-9 | 0.5-10 |
| Dodecyl sodium sulfate | 1-10 |
| Modified cellulose | 1-10 |
| Tannic acid | 1-20 |
| Benzotriazole | 0.5-10 |
| Phytic acid | 1-30 |
| Water | Surplus |
b：Regenerated additive BS-51 is formulated
| Material name | Addition % |
| Malonic acid | 5-30 |
| Potassium ferrocyanide | 10-50 |
| Polyacrylic acid | 1-20 |
| Ammonium hydroxide | 10-40 |
| Water | Surplus |
The application conditions of BW-500P are as follows：3% concentration of BW-500P, phosphoric acid 5-10% (85% industrial phosphoric acid), temperature
40-50 DEG C, time 8-30 minute.Under the conditions of ultrasound condition, spray condition or strong cyclic, removing oxide layer speed significantly carries
It is high.Regenerated additive, for precipitating metal ion therein, can be substantially reduced as the activation recovering liquid after pickle aging
Pickling cost.
The beneficial effects of the invention are as follows：Formula is reasonable, and technique is advanced, preparation science, and removing oxide layer effect is good, is not required to be eager to excel
Acid, non-exhaust emission, raw material are easily purchased, and synthesis is at low cost, reduce film forming liquid consumption, good product quality.

It weighs：3 kilograms of alcohol, 2 kilograms of tartaric acid, 4 kilograms of polyethylene glycol, AEO-9：1 kilogram, neopelex 3,000
Gram, 3 kilograms of modified cellulose, 5 kilograms of tannic acid, 1 kilogram of benzotriazole, 3 kilograms of phytic acid, 75 kilograms of water, machinery stirs after mixing
It mixes and can be obtained by the translucent environmentally friendly fast acid of the double centner present invention and clean lotion BW-500P.
B. regenerated additive BS-51
It weighs：20 kilograms of malonic acid, 25 kilograms of 15% ammonium hydroxide, pH value is in 6.0-7.0 after mixing；It weighs：Polyacrylic acid 5,000
