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

The ratio of magnesium alloys is higher than the aluminum alloy and steel, slightly lower than the fiber enhanced plastic with the highest strength, which is comparable to that of aluminum alloy and steel. So is it like other metals when performing alkaline heat treatment, the following editors will

What is plywood?Plywood is actually a kind of board bonded with adhesive. The front side of the plywood is called the "face" and its opposite side is called the "back". The one in the middle is called the "core board". Usually, the board core is made of some wood cut into thin slices, and then these

In the market, there are many types of metals, and their etching processes are also different. Signage etching is a relatively common form now. It is popular because of its low cost and stable income. However, personalized formulation is becoming more and more popular. Many, if traditional technolog
