Abstract
The present invention relates to a scale removing agent for water tanks of automobiles. The scale removing agent achieves the purpose of scale removal by dissolving water scale and rust scale in an acid medium under the precondition of effective protection for metal. The scale removing agent of the present invention can remove all the water scale in a water tank of an automobile and water side parts of an automobile engine in one time. Besides, the present invention has the advantages of simple operation, stable performance and no any damage to cleaned positions.
Description
The present invention relates to a kind of scaling agent for water tank of automobile that adopts chemical cleaning technique.
Each developed country begins one's study and develops scaling agent for water tank of automobile at middle nineteen seventies in the world, up to the present scale remover has all kinds on the world market, but these products and all kinds of automobiles that are not suitable within Chinese territory use, its reason at first is the tectonic structure difference of different areas, the world, the water quality situation can be not identical yet, therefore the accumulative composition of scale is also different in the radiator, so the prescription of scale remover can't be completely unified.Next is that the automobile popularity rate of developed country is higher in the world, factor is understood very much and the energy dissipation, damage, maintenance, the influence that cause are normally travelled etc. to the existence of incrustation scale in the radiator, for avoiding the final appearance of this class situation, car steering person's year regular scaling agent for water tank of automobile that adds every half a year to one, carry out the scale removal maintenance, the formulating of recipe of scale remover also is to generate total amount according to the incrustation scale during this to formulate.Automobile daily maintenance part in the automobile specification sheets of China's import all has this regulation.
China domestic market occurred three in recent years, four kind of scale remover, its prescription is formed and using dosage is foreign imitation product and through improveing basically, simultaneously external imported product also once occurred on market, but do not cause result of use poor owing to conforming to China's national situation, finally on market, make no public appearances.Cause this result's reason to be that also China's automobile assembles in a large number from bringing into use to the water side part incrustation scale of water tank, engine, cause the difficulty of travelling, even just consider to clean can't travel the time.And use this moment currently available products or external import scale remover on the market to have no effect, because this series products itself does not have the effectiveness of removing a large amount of incrustation scales.
In addition, the removing of incrustation scale in China's radiator, so far still prolong with the way of breaking the back mechanical removal and carry out, cause easily mechanical force to the damage of water tank, influence a series of problems such as can't remove in its normal work-ing life, descaling rate incrustation scale low, engine water side part.
The purpose of this invention is to provide a kind of whole incrustation scales that can reach disposable removing radiator and motor car engine water side part, simple to operate, stable performance does not damage any scaling agent for water tank of automobile that is cleaned the position.
Scaling agent for water tank of automobile of the present invention is under the prerequisite that metal is effectively protected, dissolving incrustation scale and rust deposite in acid medium.Scale remover of the present invention comprises inhibiter, for example the LW-5 wide spectrum cleans inhibiter (also sale of Shanghai Kai Najie chemical institute production, main component is thiocyanate-, thiocarbamide and hexamethylenetetramine) and hexamethylenetetramine, and acidic descaling agent, nitric acid for example, oxyacetic acid, thionamic acid and EDTA-Na
2, and an amount of water.
When scaling agent for water tank of automobile of the present invention was used for the scale removal of general-utility car water tank, the consumption of each component was respectively the inhibiter of 3.2%-3.8% (weight), the acidic descaling agent of 41.5%-54.8% (weight) and the surplus water that removes amount.When scaling agent for water tank of automobile of the present invention was used for the water box for car scale removal, the consumption of each component was respectively the inhibiter of 8.0%-8.7% (weight), the acidic descaling agent of 35%-37% (weight) and the water of residual content.The common in use thin up of above-mentioned medicament becomes 5%～10% the aqueous solution.
In order to improve the scale removal efficient and the descale effect of scale remover of the present invention, it also can contain a small amount of other additive, comprises the protective material to inhibiter, for example EDTA-Na
2Speed of response promotor, for example penetrating agent BX (Shanghai auxiliary agent head factory is made and sold, and main component is a sodium butylnaphthalenesulfonate) and dinonyl naphthalene sulfonate barium; Remove Hydrogenated Polyisobutene, for example Triton X-100 and Sodium dodecylbenzene sulfonate; Remove grease auxiliary agent, for example Repone K; And tin, zinc coating protective material, for example dicyclohexyl amine octanoate, dinonylnaphthalene sulfonic acid sodium and LW-5 wide spectrum clean inhibiter.
Scaling agent for water tank of automobile of the present invention overcomes thoroughly that dismounting, manpower are struck off, grow servicing time, easy damaged, must specialized factory's maintenance, problems such as expense height.Any officer is feeding operations voluntarily all, and, can in two hours, reach medicine to the effect that dirt removes, solved the problem that the automobile radiator descaling aspect accumulates all the year round.And there is not any detrimentally affect.
The incrustation scale, the rust deposite that not only are applied in radiator and engine water side are removed, simultaneously also can be applicable to by stainless steel, carbon steel, low alloy steel, copper and copper alloy the incrustation scale of any watering equipment that aluminium and aluminium alloy are formed, container, pipeline etc., the quick removing of rust deposite.
