Corrosion brands factory finish several corrosion of metal plate surface treatment method

Corrosion brands factory finish several corrosion of metal plate surface treatment methods of etched plates also called corrosion plates. Primary check through mask, etching processing 3 processed making of braille metal plates or concave word metal plates. Etching work - now - - - - - - > corrosion brands factory finish several corrosion of metal plate surface treatment methods of etched plates also called corrosion plates. Primary check through mask, etching processing 3 processed making of braille metal plates or concave word metal plates. Now etching technology has very mature and general factory can independent operation. First is the expected, according to the drawing requirements ( Page size) The size of the around with no less than 5 mm above the burrs. Cutting board with 720 type pedal plate shears, requirement surface level off, without margin. And then the corrosion sign of surface treatment. Corrosion plates factory on metal corrosion plates surface treatment: ( 1) Mechanical polishing: in 2. 2 - 4 kw polishing machine, mechanical polishing of woollen cloth round of 300 - use Motor speed generally 2000-350 3000 r/min. ( 2) Alkali treatment: with a 10 - Sodium hydroxide in 65-15% Will metal plate to boil 10-85 ℃ water solution For 30 seconds, and then remove with clean water, immersed in a 5% weight inscription acid in aqueous solution. ( 3) Powder processing method: use a flat brush dips in old pink, Double pink) Will board evenly brush all ears, cross the crossover to until to remove dirt, and removing the effect of oxygen skin, and then closed with 5% potassium dichromate solution. ( 4) Wire drawing processing method: use mechanical or manual drawing method, the metal plate wire drawing processing, metal surface in order to achieve regeneration effect. ( 5) Some paint baking method. According to design requirement of corrosion of sign, and then in the above point paint ( According to the requirements on different color) , zui before baking.
