Description
Technical field
The present invention relates to a kind of clean-out system, belong to steel product and material surface treatment industry technical field, the particularly antirust scavenging solution of the zinc-plated shell of a kind of sensor, be mainly used in zinc-plated front or zinc-plated rear hydrochloric acid cleaning technique.
Background technology
Because zinc is soluble in acid, also can be dissolved in alkali, therefore claim it to be amphoteric metal.Zinc changes hardly in the air of drying.In malaria, zinc surface can generate fine and close zinc subcarbonate film.Concerning steel substrate, zinc coating belongs to anodic coating, and it is mainly used in the corrosion preventing iron and steel.Zinc coating is through significantly improving its protective and ornamental.
Zinc-platedly refer to that plated surface one deck zinc at metal, alloy or other material is to play the process for treating surface of the effect such as attractive in appearance, antirust.The main method adopted is pot galvanize now.
the pot galvanize of metal products be the most substantially, one of the most effective anticorrosion process.The metal products that can carry out pot galvanize comprises steel wire, sheet material, coil of strip, steel pipe, structural part and fastening piece etc.
Metal products must carry out surface treatment before zinc-plated, to remove the pollutent such as oil, rust, dust that surface of metal product produces depositing, in the process such as thermal treatment, or lubricant, phosphatize phosphate coat etc. that surface of metal product is originally remaining.
Therefore, in the course of processing of continuous hot-dipping galvanizing metal products, include the step such as pre-wash step and pot galvanize.The responsibility that pre-wash step is taken on is that removing attaches at the greasy dirt of steel strip surface, iron filings, iron rust and trifle in the world etc., use and make metal products enter pot galvanize step under the state obtaining the abundant cleaning in surface, ensure that overlay coating and metal products have excellent sticking power.
Self-evident, the quality of pre-washing effect can directly have an impact to the metal products after zinc-plated.At present, industry comprises the operation that pre-wash step uses: alkali lye spray, alkali lye are scrubbed, electrolytic degreasing, clear water are scrubbed and clear water rinsing.But, facts have proved that foregoing sequence is difficult to fundamentally remove the oxide compound of steel strip surface, be especially dispersed in oxide compound in the microscopic pits of surface of metal product and silicomanganese for that be mingled with alloyed oxide a little with uneven state.
Disclosed in 5 days December in 2007, application number is No. 200710025061.3 Chinese invention patents, the name of its innovation and creation is called " a kind of galvanizing metal detergent ", it comprises organic complexing agent, phenanthroline, water, and the weight ratio of organic complexing agent, phenanthroline, water is 3-10:0.005-0.04:100.
Above-mentioned patent application, the ingenious solubility for scale that make use of organic complexing agent, can effectively wipe oil and calcium ions and magnesium ions, and phenanthroline then effectively eliminates free ferrous ion.But for surface of metal product, the oxide compound in especially micro-hole, as iron rust etc., also has silicomanganese to be mingled with and is a little then difficult to remove.
Therefore, when metal products enters zinc-plated, these oxide compounds just can hinder the reaction of zinc and iron, are difficult to form mesophase spherule, so zinc coating is only the surface sticking to metal products as machinery, bonding force is between the two comparatively fragile.The meeting after being put to use of this galvanized metal goods, in the short period of time, exposes the problem affecting work-ing life because of corrosion-resistant.
Therefore for improving the permanent corrosion resistance nature of metal products, at present, still the general concentrated hydrochloric acid that directly uses descales.
Disclosed in 7 days December in 2011, application number is No. 201110247897.4 Chinese invention patents, the name of its innovation and creation is called " a kind of band steel hot-dip galvanizing technique ", it comprises (1) step strip cleaning treatment step, this step is specially: first carry out cleanup acid treatment after the uncoiling of band steel and remove oxide film, Acidwash solution to be concentration be 25-30% hydrochloric acid, Tween-60 0.5-0.8% and water; Then directly electrolytic degreasing process is carried out without clear water, the formula of electrolytic degreasing solution is 10-15 parts, sodium carbonate by weight percentage, sodium phosphate 20-25 part, sodium hydroxide 60-70 part and water 270-300 part, the temperature of electrolytic degreasing is 60^-800C: enter Rinsing Area after electrolytic degreasing and clean.
Application number disclosed in 26 days March in 2014 is No. 201010331138.0 Chinese invention patents, the name of its innovation and creation is called " the improvement hot galvanizing method of a kind of iron handicraft or furniture ", it comprises (1) step and carries out oil removing defatting step to workpiece: namely in degreasing tank, add sulphuric acid soln, then OP-10 and di-o-tolyl-thiourea is added, keep mixing liquid 60-65 degree Celsius, workpiece is all immersed, till workpiece is flooded profit completely; (2) step descaling step: namely add hydrochloric acid soln in pickling tank, then adds phosphoric acid, alkylphenol polyoxyethylene, sodium lauryl sulphate and ethylenediamine tetraacetic acid (EDTA), is all immersed by workpiece, cleans 10 minutes.
Above-mentioned two patent applications, still exist following not enough:
1. all employ hydrochloric acid, because hydrochloric acid acidity is comparatively strong, and there is larger volatility, in acid cleaning process, often occur " excessive erosion " and " acid mist " phenomenon.Metal products matrix will be caused thus to be corroded, large losses material, and consume excessive hydrochloric acid, and not only shorten hydrochloric acid work-ing life, treatment capacity is reduced, and overflow because of acid mist and cause workshop air quality to be affected, serious harm workman is healthy.
2. needed for, scavenging period is long, and " acid mist " that cause hydrochloric acid to be formed increases the etching time of metal products matrix, therefore corrosion rate increases.
3. mainly can remove greasy dirt and the rust staining of metallic surface, but how antirustly not provide terms of settlement.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide the zinc-plated shell of a kind of sensor antirust scavenging solution, the zinc-plated shell of this sensor can suppress the formation of excessive erosion and acid mist with antirust scavenging solution, save material and hydrochloric acid consumption, improve hydrochloric acid work-ing life, and environmental protection.
