Masking tape is a material shape, very extensive membrane can be so simple substance element or compound or complex, it can also be an inorganic material or organic material. Masking tape with the same bulk material can be so amorphous, polycrystalline or monocrystalline state. The past 20 years, masking tape rapidly launch science, skills in preparation, analysis methods, structure and composition of the mechanism of investigation and other aspects of the study include the contents of the extreme abundance of livestock. Meanwhile, the development and use of inorganic masking tape is even more rapid. Very obvious.
　　Inorganic masking tape from the film can be divided into glass, ceramic film, a metal film, a zeolite film. From the thickness of masking tape to see, it has a thickness of only super masking tape products. From the use of perspective, there is a gas used for parting; both have for parting, but also has the function of the catalytic reaction; both also for corrosion, but also has a decorative effect; particularly for electronic information skills, a variety of functions not only for electronic products of small, lightweight, high-density and high reliability plays a decisive role, and through a combination of textured paper produced a new special function. Masking skills still is an ongoing interdisciplinary, during which many issues were also being explored. 76-6
　　Masking functions varied, with electrical function, mechanical function, an optical function, magnetic function, catalytic function, superconducting functions. Thus, not only has masking tape on the industry widely used, especially in the modern electronics industry led the city also has extremely important position, but also the world in the primary content of this collar city competition, and from one side represents a the technological level of the country. Existing technology is now a lot of film, there are coating methods, sol - gel method, chemical plating solution, oxidation, ion deposition, physical transpiration method, a chemical deposition method, a molecular beam epitaxy method. How to pick a way, it should according to the specific circumstances. Sometimes a certain kind of preparation Masking There are several ways to choose from, but the primary induction should think in terms of function requirements and technical sophistication of factors such as masking tape to the resolution.
