Three kinds of thin film materials for thin film panel, according to the introduction, suitable for making thin film materials, according to its types, ordinary PC, PVC, pet three; according to its surface state and sand surface (translucent 3 film) and light surface (transparent film) point. PC materials have excellent physical chemistry properties and are widely used in inks. Is the membrane switch panel in common use material. Prestressed concrete materials differ from sand surfaces and smooth surfaces. The reason for choosing the sand surface material is that the use of the thin film switch is mostly electronic, and the panel as the control system does not want to be disturbed by the light. The sand surface only has diffuse reflection and will not produce bright reflection, at the same time, due to the disorder of the sand surface, it has the function of hiding scratches, on the contrary, the smooth surface material does not have the above characteristics. But as a gloss material, once printed on the back, the color will be bright and eye-catching, and in need of strong decorative requirements and do not need regular contact, often choose gloss material to make panels, or because of the special needs of certain display areas, such as liquid crystal display, the choice of gloss materials is advantageous.PVC film material price is lower, accounting for about half of the PC material, in the production of popular products, if the choice of PVC material, can reduce production costs, and PVC material malleability, can be used cold-pressed processing stereo graphics and text. Smooth polyvinyl chloride are generally over 0.5 mm thick and are protected on both sides by pet paper or glue paper, most of which are used for making decorative panels; sand polyvinyl chloride are generally under 0.3 mm thick and are usually supplied with fixed length sheets, there’s no reel. The surface state of Pet film is usually a smooth and transparent film, in a few cases there are also sand products such as wood KB products, but the sand surface is very thin, similar to a kind of desert surface layer, in the Pet surface and get desert surface, unlike PC, it is not obtained by rolling the sand surface in a mechanical calendering process, which means that its surface is not as obvious as that of PC.
