What should be noted when installing transparent PC endurance boards?

Precautions before installing transparent pc endurance board: 1. Clean the metal frame, and there must be no metal bend oil or acid solution left on the frame. Chemical substances should remain on the frame. 2. The reserved expansion space for transparent Pc Endurance Board can be calculated by the following formula: expansion value=linear expansion coefficient x length x maximum temperature change value. The linear expansion coefficient is a fixed value=7 x 10-5 (cm/cm/℃). Example: A PC board with a length of 100cm is installed in an environment with a temperature difference of 40 ℃ between day and night. The reserved expansion space for transparent PC endurance board is: expansion value=7 x 10-5 (cm/cm/℃) x 100 (cm) x 40 ℃=0.28 (cm) Therefore, the reserved expansion space should be at least 0.28cm. 3. The plasticizer (DOP) in PVC gaskets and certain chemicals in rubber gaskets can migrate to the surface of the gasket, causing damage to the PC board upon contact. Therefore, they must not be used. It is recommended to use EPDM rubber, Silicone rubber, and Neoprene rubber as gaskets for transparent PC endurance boards. If there is no suitable gasket, it is better not to use it than to choose a gasket that will damage the PC material. 4. Sealed installation is required, and neutral Silicone series sealant, double-sided waterproof tape, and rubber pressure strip can be selected. 5. The double-sided waterproof tape of transparent PC endurance board can be used not only for waterproofing, but also as a cushioning material between PC board and frame. Some double-sided adhesive tapes have damage to the PC board, so they are also used during construction.
