Description
Technical field
The present invention relates to scale cleaning agent, relate in particular to normal temperature scale cleaning agent for automobile water tank and using method thereof.
Background technology
Incrustation scale is harmful product common in the productive life, and its main component is lime carbonate and magnesiumcarbonate.Incrustation scale is formed by three layers usually, and outermost layer is a scum, and this layer incrustation scale is very loose; Next is soft dirt layer, and this layer incrustation scale density increases, but also not scleroma fully of incrustation scale; Be hard dirt layer again, incrustation scale is scleroma fully, incrustation scale density maximum.If incrustation scale produces in irony wall containers such as boiler, then incrustation scale is formed by four layers, three first layers as mentioned above, innermost layer is because precipitation of scales, boiler iron wall generation electrochemical reaction and generate iron oxide layer.
As a rule when reaching 0.5MM, the radiator fouling do not reach the normal temperature of loosing, maldigestion can occur causes vehicle exhaust to exceed standard, because of the cooling system heat dispersion not good, temperature in the cabin raises, directly have influence on the air input of engine, cause the working order of engine to be the fuel-rich combustion state, its direct result is that the blowdown system of the inadequate fuel oil of burning by engine comes out a large amount of noxious gas emissions, directly cause topsoil, be detrimental to health.When the incrustation scale in the water tank surpasses 0.8MM, will cause the water route circulation not smooth, water temperature also can sharply rise, and it is prominent quick-fried to form water tank, and the serious ultrahigh-temperature of body directly influences oiling system, influences the works better of engine, also can damage engine when serious.
Publication number is that the document of CN 1123343A discloses a kind of scale remover that is used for radiator, and it contains one or more and is selected from nitric acid, oxyacetic acid, thionamic acid and EDTA-Na
2One or more select the LW-2 wide spectrum to clean the inhibiter of inhibiter and hexamethylenetetramine; water; can also comprise that one or more are selected from the how speed of response promotor of barium sulfonate of penetrating agent BX and dinonyl; and/or one or more are selected from the Hydrogenated Polyisobutene that removes of Triton X-100 and Sodium dodecylbenzene sulfonate; and/or except that grease auxiliary agent Repone K; and/or one or more are selected from the dicyclohexyl amine octanoate; dinonyl how sodium sulfonate and LW-5 wide spectrum cleans the tin of inhibiter; the zinc coating protective material, this scale remover exists descale effect not ideal enough; the more high defective of production cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of features high scale-removing effect and the low automobile water tank scale cleaning agent of production cost.
Another technical problem that the present invention also will solve provides the using method of above-mentioned scale removal reagent.
Main design of the present invention is based on thionamic acid or oxalic acid; be equipped with the solubility promoter vulkacit H, (main component is a di-o-tolyl-thiourea as if fourth in inhibiter Tianjin; can be in Tianjin the easy company limited of one commerce-change industry and trade buy), reductive agent tin protochloride and penetrating agent JFC (can the easy company limited of one commerce-change industry and trade buys in Tianjin); make gained scale removal reagent energy quick descaling; especially remove the automobile water tank incrustation scale; comprise iron oxide layer; and the erosion ratio to the non-ferrous metal wall is very low, and this reagent cheap, easy to use, be beneficial to environment protection.
Normal temperature scale cleaning agent for automobile water tank provided by the invention mainly is made up of following weight percent proportion raw material:
Thionamic acid or oxalic acid 70-99%, vulkacit H 0.01-10%, Tianjin is as if fourth 0.05-12%, penetrating agent JFC 0.01-10%;
Preferably, thionamic acid or oxalic acid 98%, vulkacit H 0.3%, Tianjin is as if fourth 1%, penetrating agent JFC 0.5%;
Normal temperature scale cleaning agent for automobile water tank provided by the invention also can contain following components in weight percentage: tin protochloride 0.02-0.5%,
Be preferably: thionamic acid or oxalic acid 98%, vulkacit H 0.3%, Tianjin is as if fourth 1%, tin protochloride 0.2%, penetrating agent JFC 0.5%;
Raw materials used: thionamic acid, oxalic acid, vulkacit H and tin protochloride are chemical pure, all can buy from general chemistry chemical reagent shop to obtain.
Wherein, thionamic acid is a kind of organic monoacid, and it can react with main composition-calcium carbonate, magnesiumcarbonate and the ferric oxide of incrustation scale, and insoluble substance is converted into soluble substance;
Penetrating agent JFC can be accelerated the speed of response of scale remover with lime carbonate and magnesiumcarbonate, promotes the dissolving of lime carbonate and magnesiumcarbonate;
Vulkacit H is a kind of solubility promoter, and it can be by the dissolving of mode promotes oxidn iron such as complexing;
Tin protochloride is a kind of reductive agent, and the ferric ion that ferric oxide can be dissolved in the production of acid back is converted into ferrous ion, thereby prevents the erosion to the non-ferrous metal wall;
The erosion to the non-ferrous metal wall can be prevented if fourth is a kind of inhibiter in Tianjin.
The present invention also provides and has used mentioned reagent to remove the method for incrustation scale, and this method comprises: to being filled with water by the scale removal utensil and adding scale removal reagent in proportion, soak, discharge the dissolved incrustation scale and the aqueous solution; Can also the passivation maintenance.
Particularly: will be filled with water and add scale removal reagent by the scale removal utensil, and, soak at least 8 hours if incrustation scale thickness≤3mm then drops into by the scale removal reagent of the volumetric water weight 3% of scale removal utensil; On this basis, the every increase of incrustation scale thickness 1mm, scale removal reagent input amount increases by 1%, soak time increases by 2 hours at least, as incrustation scale thickness is 4mm, input is soaked more than 6 hours at least by the scale removal reagent of the volumetric water weight 5% of scale removal utensil, discharges the dissolved incrustation scale and the aqueous solution then from utensil; Can also use sodium-chlor and passivation agents, hydrazine for example, aqueous solution soaking maintenance utensil.
Scale removal reagent of the present invention, cost is very low, and only about 2.4 yuan of/kilogram reagent use its scale removal, and especially to the automobile water tank scale removal, descaling rate can reach more than 98%, and the corrosion rate≤0.6g/hm of non-ferrous metal wall
2, the work-ing life that can improve automobile water tank.Scale removal reagent of the present invention uses at normal temperatures, and is easy and simple to handle, can not produce oxysulfide, oxides of nitrogen gas and dust and other objectionable impurities during scale removal, is beneficial to environmental protection and healthy.This scale removal reagent is powdery, is easy to preservation and transportation.
