Membrane panel is a popular text mark and trademark in recent years, which integrates decorative and functional. In PVC, PC, PET and other flexible plastic materials printing established graphics, text descriptions, transparent Windows, etc., pasted on different types of double-sided tape, made of plastic products for identification and protection. The film panel has beautiful appearance, clear graphics and good sealing. It has the characteristics of waterproof, anti-deformation, anti-pollution, anti-high temperature and strong viscosity. Widely used in intelligent electronic measuring instruments, medical instruments, computer control, CNC machine tools, electronic weighing, post and telecommunications, photocopiers, refrigerators, microwave ovens, electric fans, washing machines, electronic game consoles and other industrial and household electrical products.
The film panel uses different materials, which determines its price and performance. The film panel made by the screen printing process is characterized by:
1, the word is clear and intuitive graphics and text, and can adapt to different planes and bending planes.
2, the choice of different materials, can make PVC, PC, PET and other materials.
3, the film panel has: waterproof, anti-deformation, anti-pollution, anti-high temperature, strong viscosity and other characteristics.
Raw materials are in an unusually major step in the production process of any product, which is responsible for the appearance and protection of the product. For thin film panels, the original data should have at least:
1, good chemical resistance: that is, for most alcohols, ethers, mineral oils and other conventional chemicals should have tolerance power.
2, good weather resistance: the panel layer is the outer surface of the film switch exposed in the natural environment, and the panel data should be able to change shape, cracking, aging and discoloration under natural environmental conditions;
3, excellent appearance: refers to the appearance of the film manufacturing panel smooth, consistent luster, no mechanical damage, scratches, inclusions and color spots and other appearance defects;
4, good dimensional stability: the film requested to manufacture panels has no significant change in size within the temperature range (generally -40℃~55℃).
5, elasticity: the thin panel layer has the weakness, at the same time, the elastic deformation is small, can be judged by the extension rate of the data, generally speaking, the extension rate is large, the elastic deformation is large, and the rebound function is poor;
6, according to the above requirements, the films commonly used for film panels are usually poly (acid ester) film, polyvinyl chloride film, polyester film and polyamine ester and other films.
What are the requirements for film panel production? The film panel is widely used, it can be seen everywhere in life, refrigerator shell, microwave oven surface, washing machine button, rice cooker button, remote control shell and other daily necessities can see it. The film panel is divided into two types from the structure, the raised film panel and the flat film panel, as the film switch panel, should have the following conditions:
1, good dimensional stability: the film required to make a panel has no significant change in size within the temperature range (generally -40 ° C ~55 ° C).
2, good appearance: the film surface of the production panel is flat, the luster is consistent, no damage, scratches, inclusions, etc.
3, elastic requirements: The panel layer is required to have a weak performance, can be judged by the elongation of the material, generally speaking, the elongation is large, the amount of elastic deformation is also large, and the reverse.
4, good weather resistance: the panel layer is the surface layer of the film switch exposed to the natural environment, and the panel material does not deform, crack, aging and discoloration under natural environmental conditions.
5, good chemical resistance: the film panel layer will be likely to touch different chemicals, but for most common chemicals, mineral oil is the due tolerance.
The keys on the surface of the former are slightly puffed out in the design, and the parts of the keys are slightly higher than the other panel parts, presenting a three-dimensional panel. This type of film panel has the advantage that the user can accurately locate the position of the body.
