Put into can after the feed liquid of above-mentioned each embodiment mixes, on the production line inflator, charge into specified amount like 10 grams and reach third butane gas of rated pressure, can aerosol-type clean-out system of the present invention.
Can aerosol-type clean-out system of the present invention shakes up these article before using, and is directly injected into article surface to be cleaned, treat 20-30 seconds after, erase to get final product with soft cloth.For the serious part of spot, spray these article after 20-30 seconds, use the wiping on spot of soft brush, erase with clean rag again.
The anticorrosion scheme of can: the one, improve the purity of water, effect is well-known to ortho-water to corrosion of metal.Therefore, guarantee that the purity of water is the important step that effectively prevents the tinplate tin galvanic corrosion, the present invention requires electrical conductivity of water to be not more than 15 μ S/cm.The 2nd, add inhibiter; Inhibiter is divided into inorganic and organic two big types; The mineral compound inhibiter; Like metasilicate, phosphoric acid salt, tungstate, borate, nitrite, molybdate, benzoate etc., they can make the metallic surface form the fine and close passive film of one deck, can block or prevent oozing hydrogen and oozing the acid effect of metal.The organic cpds inhibiter, like trolamine, benzotriazole, mercaptobenzothiazole, organophosphate etc., corrosion inhibition is better.The corrosion mitigating effect that improves inhibiter is a key of the present invention, and the present invention adopts the compound prescription of inorganic and organic multiple inhibition material, and corrosion mitigating effect reaches requirement of products, and cost is attend enterprise and also can be accepted.The 3rd, select surfactant types; Through experiment repeatedly; The anionic group of our table of discovery surface-active agent such as sulfonate radical, cl ions etc. have destruction to the passive film of metallic surface; The present invention has screened three kinds of nonionogenic tensides, under the prerequisite of the clean effect that guarantees clean-out system, has avoided the generation of this type of anionic group destruction effectively.
Proof test of the present invention is following:
Comparative example A: sulfonic acid 2 grams, polyoxyethylenated alcohol sodium sulfate (AES) 2 grams, AEO (AEO-9) 1.5 grams, ethanol 5 grams, trolamine 3.5 grams, Sodium Benzoate 1 gram, tripoly phosphate sodium STPP 1 gram, deionized water 83.6 grams, essence 0.4 gram.
Comparative Examples B: polyoxyethylene nonylphenol (TX-10) 2 grams, AEO (AEO-9) 3 grams, fatty acid distribution of coconut oil diglycollic amide (6501, model 1: 1.5) 1 gram, ethanol 5 grams, trolamine 3 grams, Sodium Benzoate 1 gram, Sodium orthomolybdate 0.8 gram, soft water 83.8 grams, essence 0.4 gram.
The feed liquid of comparative example A, Comparative Examples B and embodiment 5 is put into jar respectively, add third butagas after, put into 55 ℃ ± 1 ℃ water-soluble pot, take out 2 week backs (336 hours), opens the aerosol jar and observe the inner wall corrosion situation.
Experimental result:
The comparative example A: the can seam burnt hair has many places scale spot, moderate corrosion.
Comparative Examples B: the can seam burnt hair has the little rust staining in a place, mild corrosion.
Embodiment 5: tank body light, no rust staining, no corrosion phenomenon.
Conclusion:
The corrosion mitigating effect of the purity of the character of tensio-active agent, water, inhibiter has direct relation to the corrosion of tank body in the material; Select suitable tensio-active agent for use; The purity of control water, the compound interpolation of organic and inorganic inhibiter can well solve the etching problem of can aerosol-type tank body.
