Description
Technical field
The invention belongs to the metallic material surface detergent technical field, be specifically related to front non-phosphor degreaser liquid of a kind of cold rolled sheet pot galvanize and preparation method thereof.
Background technology
Pot galvanize (galvanizing) also be galvanizing and galvanizing: be a kind of effective anti-corrosion of metal mode, be mainly used on the metal construction facility of every profession and trade.Be that the steel part after the rust cleaning is immersed in about the 500 ℃ zinc liquid that melt, make the steel component surface adhere to the zinc layer, thereby play the rot-resistant purpose.Along with the discovery of industry, the pot galvanize product has applied to a lot of fields, and the advantage of pot galvanize is that the anticorrosion time limit is permanent, and conform extensively is the method for anticorrosion treatment that is popular always.
The production of galvanized sheet, no matter be electro-galvanizing or pot galvanize, in order to obtain good zine plate surface, necessary surface uniform before cold rolled sheet is through the zinc pot, existence without grease and other residue, otherwise plating leakage will occur, produce the surface imperfection such as zinc granule, zinc scar, have a strong impact on lumber recovery and the product quality of zine plate.Therefore must clean up the residues such as the ROLLING OIL of the cold rolled sheet remained on surface behind the process cold rolling, iron powder.Principle according to grease-removing agent can be divided into: chemical degreasing, electrolytic degreasing, ultrasonic degreasing, chemical degreasing is saponification, emulsifying effect and the complexing action of performance grease-removing agent, by the mode of wetting, infiltration, rolling off, dispersion and solubilising, the grease of surface of steel plate is removed.
In recent years, along with the fast development of China's steel industry and galvanized sheet industry, the methods of removing the steel surface residue all are studied, the research of grease-removing agent is one of research branch that wherein relatively enlivens.Be that CN100547118C has reported a kind of be used to rolling chill volume degreasing agent for cleaning such as patent publication No., it is a kind of phosphorous powder grease-removing agent; The phosphorus of phosphorous powder grease-removing agent easily causes environmental pollution, and the life publication number that seriously also can endanger the people is: CN101407916A has reported a kind of low-alkali non-phosphate degreasing agent, and it is to be exclusively used in the zinc-plated front cleaning of steel plate hot, is a kind of without phosphorus powder grease-removing agent.Because present degreasing production line all is by the design of liquid grease-removing agent, the powder grease-removing agent approaches to be eliminated.CN101629299B has reported a kind of electroplating degreasing agent for secondary cold rolled material, and this grease-removing agent is the liquid agent of non-phosphate degreasing, is exclusively used in the front cleaning to the cold-reduced sheet surface residue of eleetrotinplate.CN101457366A has reported a kind of grease-removing agent for cleaning steel plate, and the steel plate correlation circumstance after cleaning efficiency and the cleaning has no report.CN101476131A has reported a kind of foamless low temperature degreasing agent, is used for the cleaning of surface of steel plate.
