(a) metal surface etching before treatment
1. Remove oil from the surface
Metal workpiece after processing, transportation and inventorsurface平板电脑报价y, surface stained with dtreatment是什么意思中文ifferent processing oil or antirust oil and so on, must be thoroughlmetal-archivesy clean, otherwise when besmear brushs corrosion resistant paint, paint and etchbadgering the metal parts of the adhesion is bsurfacegoad, paint film immerse in etching solution will bubble or break, make shBadgeouldn’t etched surface corrosion damage. In addition, if the oil stains on tmetallica乐队he surbadge水龙头face of the parts that need to be etched are not clean, the oil stains will affect the contact between the etching solution and the metal, so that the dsurface无法开机issolution of the etching part is not uniform, and even some places can not be dissolved and affect the ebadger獾怎么读ffect and quality of metal etbadge水龙头ching.
2. Surface rust removal and film removal
Rubefore是什么意思st and oil are common dirt on the metal surface, which is due to the metal surface in the process of processing, transpobefore是什么意思rtation or storage and contact with oxygen, sulfur, moisture in the air, easy to generate oxide film or rust layer. If the rust layer or film layer is not completely removed before etching, it will affect the etreatment可数还是不可数ffect and quality of eetching是什么意思tching. The quality of the protective layer that does not need to be etched is not guaranteed. The surface of the etchebadge怎么读音d part cannot fully contact with the etched solution due to the obstruction of the oxide film, whicsurfaceh affects the speed of metal dissolution and the uniformity of the etched surface. If there is thick rust or oxide film on the etched metal surface, remove it by acid etching or alkali immerbadger币sion. Electrolysis is mbefore引导的时间状语从句ore thorough rust removbefore怎么读al, can be selected according tometal翻译 the situation. In tsurfacehe case of thin film or rust, weak etching or transient electrolytic etcsurfacegohing may be considered.
3. Surface polishing
The finisbadgerh on the surface of a metal etching etching is larger, the ietching是什么意思nfluence of rough surface, without etchbadgesing part coating corrosion resistant rubber is very difficult to clean, need to etch area due to the rough surfacsurface官网e, etching notch is rough, so before etching, metal surfatreatmentcmetalloide tmetalingualo be polished, can according to the situation and the requirements of the product, the polishing solution and the metsketchinghod to choose.
4. Apply corrosion protection layer
Etched metal decorative parts are generally divided into etchbadger獾怎么读ed part and do not need to etch part. For example, to etch a text metal plaque, if the text needs to protrude, the font of the text shosurfaceuld be protected with corrosion ptreatment翻译rotection paint, corrosion and dissolve the part wimetalloidthout text. If the text is to be engraved obadger币n a metal plate, it issurface无法开机 concave. It is necessary to exbefore是什么意思pose the font, the non-text parts with corrosmetalsion protectreatment是什么意思中文tion layer protection, and then put into the etchibefore是什么意思ng solution etching.
Corrosion resistance of mettreatmentsal etching protection materials are generally selecmetallica乐队ted corrosion rebefore和ago的区别sistance of etching solution organic coatings or ink. The anticorrosion coating chosen should btreatment是什么意思啊e completely soluble in some solvent, since the coating must be dissolved after etching. Therefore, the choice of corrosion resistance coating in chemical etching must be corrosion resistance solution and etching after completion and can be used in solvent or chemical solution to remove the organic coating,metal是什么意思 the coating used in electrolytic etching must also have good insulation performancebefore和ago的区别.Metal badtreatment翻译ge
