The amount of membrane used in laminating machine is mainly related to the operation level. It is recommended that:
1. The product to be constructed must be straight. It is necessary to deal with uneven paper with "leaf edge" and "tight edge" phenomenon. “Ruffled†paper can be baked, and “tight†paper can be hanged.
2. Be sure to wait for the blot to dry before you can cover the film, otherwise it will cause foaming or pulling.
3. Spray as little as possible during printing, otherwise it will cause emptying and foaming at the pile. The powder should be removed before the film is coated. If the number of prints is large, the powder can be hanged and dried, and the number of prints can be manually wiped.
4. When paying the film, pay attention to the direction of the paper thread, especially the thick paper, to reduce the curling of the paper due to the rolling and stretching.
There is also: the temperature is generally controlled to 40 ~ 60 ° C. Too high a temperature will deform the paper and film, causing the product to curl, but it should not be too low, otherwise it will cause insufficient viscosity. The coated paper temperature should be slightly lower than the offset paper.
Compared with silver mirrors, copper-free mirrors are of a higher grade. After the Silver Mirror is plated with silver, a layer of copper will be plated to protect it to prevent the mirror from being damaged and easily scratched. The copper-free mirror is to replace the copper protective film with a passivation protective film, making the mirror more environmentally friendly and durable. The passivation protective film of the copper-free mirror makes the mirror more wear-resistant, and is superior to ordinary silver mirrors in adhesion and corrosion resistance.
In addition, we also sell Silver Mirror glass, silver mirror commonly known as waterproof mirror, mercury mirror, silver-plated mirror on glass surface, glass mirror, mirror glass, etc. Silver mirrors are widely used in furniture, handicrafts, decoration, bathroom mirrors, cosmetic mirrors, optical mirrors, and car rearview mirrors.
