Three minutes to understand ceramic membrane
2023-06-06
As a kind of solid membrane, ceramic membrane is a ceramic filtration and separation material with porous ceramic as carrier and microporous ceramic membrane as filter layer. The pore size of ceramic membrane is 0.004~15μm, in tubular and multi-channel shape, and its main materials are: Al2O3, TiO2, ZrO2, SiO2 and other inorganic materials.

Principle of sputtering thin film deposition technology
2023-06-06
Sputtering deposition is a physical vapor deposition technique in which particles are ejected from a solid target by bombarding it with high-energy particles. It is an electronic process for depositing thin films of metals or other materials onto various surfaces. In most cases, sputtering is used to apply thin coatings on silicon wafers, solar panels and displays.

What are the characteristics of sputtered films?
2023-06-06
Whether the thickness of the plated layer can be controlled at a predetermined value is called film thickness controllability. The desired film thickness is reproduced with multiple repeatability, called film thickness repeatability. Since the discharge current and target current of vacuum sputtering coating can be controlled separately. The film thickness can be controlled by controlling the target current. Therefore, the importance of the controllability of the film thickness of sputter coating is good, and it is possible to reliably coat a predetermined thickness of film. Moreover, sputter coating can obtain a uniform thickness of film layer on a large surface.

Types of anti-counterfeit film of anti-counterfeit labels
2023-06-06
Many anti-counterfeiting labels will be scattered with a layer of film, the film can make the anti-counterfeiting label better combined with the product, and not easy to damage. There are also many types of security films, each with different specifications and physical and chemical properties, and with different scope of application. Not many people may know about security films and what kinds of films they have.
