　　What is a metal corrosion sign

　　Metal corrosion signs are also known as etching signs. The first step is to select a convex metal label or a concave metal label that is processed and manufactured through three steps: mask, etching, and post-processing.

　　Surface treatment of metal corrosion signs:

　　1. Mechanical polishing: Use a 2.2-4 kW polishing machine to mechanically polish the raw material, and use a 300-350 motor to rotate the cloth wheel at a speed of generally 2000-3000 revolutions per minute.

　　2. Alkali treatment: Boil the metal plate with 10-15% sodium hydroxide in an aqueous solution at 65-85 ℃ for 10-30 seconds, then wash it with clean water and immerse it in a 5% hydrochloric acid aqueous solution.

　　3. Powder treatment method: Use a flat brush dipped in old powder (double powder) to evenly insert the plate in a cross pattern, and listen carefully until the dirt or oxygen skin is removed. Then, seal in a 5% potassium dichromate aqueous solution.

　　4. Wire drawing method: By using mechanical or manual wire drawing methods, the metal surface is subjected to wire drawing treatment to achieve the effect of metal surface regeneration.

　　Classification of metal signs

　　Metal corrosion signs include stainless steel signs, titanium signs, aluminum signs, copper signs, and processing for metal material surfaces.

　　The purpose of metal corrosion signs

　　What is the purpose of metal corrosion signs? In our lives, we can come into contact with many metal signs, and their application in various fields of modern society is also increasing. What exactly is the purpose of metal signs? So today, Xiduqing Sign Factory will introduce the use of metal signs to everyone.
