How to check the quality of Anti-ultraviolet membrane keypads
Time of issue：
There are many kinds of Anti-ultraviolet membrane keypads, some are flat, some are raised, some are flexible, some are rigid, etc. The manufacture of Anti-ultraviolet membrane keypads has certain requirements for the panel, and the panel is the decoration of the appearance of the product. In order to achieve the protective effect, the film in the manufacture of Anti-ultraviolet membrane keypads must meet certain conditions to produce high-quality Anti-ultraviolet membrane keypads.
First of all, the appearance is good, and the appearance should be flat and glossy. There is no mechanical operation, scratches, inclusions and stains and other surface defects. Secondly, the weather resistance should be better, and it should not be deformed, cracked, aged and discolored under certain natural environment conditions. With good chemical resistance, the panel layer will have different chemicals, but for most common chemicals, such as alcohols, ethers, and mineral oils, it should have a certain resistance.
Generally, the keys on Anti-ultraviolet membrane keypads only use color to express the position, shape and size of the key body. In this way, the accuracy of the operation can only be recognized by the operator's vision, because there is no appropriate reflection information to indicate whether the finger is pressed on the effective range of the switch to make the switch move, thus affecting the confidence and operation accuracy of the monitoring of the whole machine. speed. A kind of Anti-ultraviolet membrane keypads that make the key body of the switch slightly protrude slightly higher than the panel to form a three-dimensional shape, which is called a three-dimensional key switch.
