Abstract
The invention discloses a cleaning solution for a sensor galvanizing shell. The cleaning solution for the sensor galvanizing shell is mainly composed of sorbitan fatty acid ester, XP70, gluconate, an additive, an acid fog inhibitor, hydrochloric acid and deionized water, wherein the additive is mainly composed of 1-aminoethyl-2-heptadecenyl imidazoline and urotropine. On the one hand, the 1-aminoethyl-2-heptadecenyl imidazoline can realize oriented absorption on a metal surface to form a hydrophobic layer so as to play a shielding role, inhibit acid fog formation and prevent overetching of the metal surface, and also can reduce the lightness of iron ions and prolong the service life of hydrochloric acid. The additive, the sorbitan fatty acid ester and XP70 have a good synergistic effect, thus being in favor of fast dissolution and spalling of rust, oxide film and the like, acceleration of cleaning, and substantial shortening of the cleaning time. Also, urotropine and gluconate have a good synergistic effect.
Description
Technical field
The present invention relates to a kind of clean-out system, belong to steel product and the zinc-plated shell scavenging solution of material surface treatment industry technical field, particularly a kind of sensor, be mainly used in zinc-plated before or zinc-plated after hydrochloric acid cleaning technique.
Background technology
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.
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.
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. 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.
