Abstract
The invention discloses a kind of compound method of aluminum heat exchanger restrainer, with aniline as inhibiter and defoamer, with the tensio-active agent is degreasing pickling inhibiter and auxiliary agent, utilize aniline, glycerol and anion surfactant and coordinative role, having solved can not be with the problem of chlorohydric acid pickling stainless steel and aluminium matter heat-exchange equipment.This aluminum heat exchanger restrainer not only can clean the various hard scales in stainless steel and the aluminium matter heat-exchange equipment, and for removing soft dirt special-effect is arranged.
Description
The invention belongs to a kind of compound method that is used for the restrainer of heat-exchange equipment matting such as aluminium matter, stainless steel.
As everyone knows, matting is utilized acid, alkali or organic sequestering agent exactly, chemical agents such as dispersion agent, and the dissolving of settlings such as the incrustation scale that will adhere to by chemical action, mud cleans up.
At present, people generally believe: pickling mainly is hard scale and the burning corrosion product that easily is dissolved in acid at those; As for to silicate scale, the effect of anhydrous calciumsulphate dirt etc. is limited; To suspended solids, biological sludge and other organic sediments effect are littler; And, if when equipment such as stainless steel, aluminium is arranged in the system, can not select hydrochloric acid for use, and should select for use 5～10% rare nitric acid or 15% phosphoric acid to clean, and the temperature that hydrochloric acid cleans generally to be controlled between 20～30 ℃.
Yet because hydrochloric acid is used generally than other acid and is cheap and easy to get, safely, conveniently, the speed of dissolving with hydrochloric acid corrosion product and incrustation scale is faster than the sulfuric acid of same concentration in the operation.But in view of traditional viewpoint thinks that hydrochloric acid can not clean the weakness of stainless steel and aluminium, this has just limited the purposes of hydrochloric acid as pickling of stainless steel and aluminium matter heat-exchange equipment widely, and simultaneously, also the pickling for stainless steel and aluminium matter heat-exchange equipment has brought many difficulties.
The object of the present invention is to provide a kind of compound method of 1 aluminum heat exchanger, 1 restrainer.This aluminum heat exchanger 1 restrainer is different with traditional prescription, can be used in the chlorohydric acid pickling of stainless steel and aluminium matter heat-exchange equipment.This aluminum heat exchanger 1 restrainer is on the basis of conventional formulation, add a kind of composite components that contains tensio-active agent, form mutual the coordination and rigorous scientific formula on the function with aniline, glycerol, compare with other restrainer, on the effect or benefit (expense) goes up, tangible progress is all arranged on the method.Its advantage is:
1, prescription is simple, and medicine is cheap and easy to get;
2, expense is low, just the sixth of usual method;
3, easy and simple to handle, save time, can be used for unit and clean or the cleaning of not stopping;
4, before the pickling, need not carry out alkali cleaning, after the pickling, not need soda boiling and passivation film to handle.
Characteristics the most outstanding of the present invention, be exactly not only use hydrochloric acid can pickling of stainless steel and aluminium matter heat-exchange equipment and this kind equipment in various hard scales, and to cleaning suspended solids, biological sludge and other organic sediments have special efficacy.
HYZ-8901 restrainer provided by the present invention also can be widely used in the restrainer of sulfuric acid, nitric acid, phosphoric acid, acetic acid, citric acid, thionamic acid and hydrofluoric acid or above-mentioned certain several nitration mixture.
The objective of the invention is to be achieved through the following technical solutions.
A kind of compound method of HYZ-8901 restrainer is characterized in that:
1, technical recipe:
A, acid solution (is example with the technical hydrochloric acid) concentration 2.0～7.0%;
B, aniline (general reagent) concentration 0.05～0.15%;
C, glycerol concentration 0.05%;
D, surfactant concentration 0.10～0.30%;
E, all the other are phreatic water or soft water.
2, order of addition of ingredients:
In pickling system, be full of water earlier, add tensio-active agent, making its weight percent content is 0.10～0.30%, beat in the working cycle and add aniline, making its weight percent content is 0.05～0.15%, adds glycerol, making its weight percent content is 0.05%, then, add technical hydrochloric acid again, making the HCI weight percent content is 2.0～7.0%.
3, technological process control:
A, temperature control :-5～50 ℃.In the working cycle, temperature is controlled at 30～50 ℃, needn't be too high.Stop and clean, be lower than under the room temperature and still can carry out.
B, time control: how many interior dirts of viewing system measured and decided, and is generally 1～2 hour.
C, dose control: soft dirt amount is many in the system, can improve surfactant concentration, simultaneously acid strength is improved a little; Hard scale is many in the system, acid strength can be brought up to the upper limit, increases aniline concentration simultaneously, improves surfactant concentration a little.
D, monitoring analysis: monitor by general pickling required standard method, in the acid cleaning process, add acid solution, look soft dirty dropping situations supplementary table surface-active agent, but do not add aniline by analysis.
E, dynamically test piece: corrosion rate: fine aluminium≤0.05g/m
2H.Stainless steel :≤0.2g/m
2H.
Tensio-active agent among the present invention is the degreasing pickling inhibiter, and infiltration, absorption, dispersion, foaming effect are arranged again.This tensio-active agent can be that single component is as 12～octadecyl Phenylsulfonic acid or 12～octadecyl benzene sulfonic acid sodium salt or pentadecyl SULPHURYL CHLORIDE or sodium lauryl sulphate or its certain several mixture, but compound surfactant preferably is as Y-2 type and the compound ammonium bicarbonate additive of C type or the like.
Aniline among the present invention is inhibiter, is again the defoamer of tensio-active agent.
Below in conjunction with embodiment the present invention is further described.
Embodiment:
Prescription (by the 1000kg aqueous solution is that benchmark calculates, and HCI100% is an example with the hydrochloric acid folding): HCI20～70kg, tensio-active agent 1～3kg, aniline 0.5～1.5kg, glycerol 0.5kg.
By four process operations, be made into the pickle solution of HYZ-8901 restrainer, the steps include:
A, at 1m
3In the container, add 500kg clear water or soft water, add 1～3kg tensio-active agent, stir.
B, adding 0.5～1.5kg aniline, the 0.5kg glycerol stirs.
Technical hydrochloric acid 20～70kg of C, adding folding 100%HCI stirs in container.
D, add clear water or soft water to 1m then
3Till container is full of.
