After etching, the products are metal color, and many of them need subsequent surface coloring treatment: a surface color whitening treatment; b surface mirror bright treatment; c Surface coloring treatment.1. Surface color whitening treatment: precision etching products in the process of processing

How to deal with environmental problems during metal etching processing？The factors affecting the golden etching process are mainly acid, alkali, and iron chloride. It must be properly treated with waste coating and must not be discharged casually. For acid and alkaline wastewater, they are generall

The decoration is inseparable from the board, and there will be multiple plastic panels in the selection of board. When it comes to plywood, how many layers do it have? Which one is selected?The conventional size of the multi -layer plywood is 1220mm*2440mm, and the thickness specifications are main

Phosphorus is a process of reaction of metal and dilute phosphate or acid phosphate solution to form a phosphate protective film. It is one of the ways to replace the treatment of poisonous chromate. On the surface of the metal, it generates a layer of non -metal, non -conductive, porous phosphate t

How to increase corrosion resistance on the surface of magnesium alloy?Magnesium alloy is the lightest metal engineering material in industrial applications. Its density is low, only 2/3 of the aluminum, 1/4 of the iron, and has excellent damping and electromagnetic shielding performance. It is conv

The thermal transfer machines and the gold perm were transferred on the medium through stress and heat sources. The gold perm is a device with a certain temperature and pressure to the surface of the item, and the thermal transferor is a silicone roller to use the heat transfer ink specialty to the

What are the issues that need attention when etching processing of optical inks？The problems that should be paid attention to in the process of using the photosensitive ink during etching are mainly the following points:1. Drying temperature and time: In order to achieve the effect of the coating, y

What is a hot stamping machine?The hot stamping machine is a kind of device that uses a golden hot spinning process to complete printing. As for the bronze technology, it is a process that uses high temperature and high pressure to print the electrolytic aluminum foil to the bearing material. It is
