PC endurance board installation method:
1. When installing the PC board, firstly remove the protective film on the edge surface of the PC board by about 10cm, so as to bond the neutral sealant and the PC board to achieve a better waterproof effect.
2. In order to prevent thermal expansion and contraction, at least 10 mm of telescopic clearance should be reserved at the joint between the two plates (with a span of 2M) when installing the PC board. For example, if the span is large, the reserved expansion space depends on the thermal expansion coefficient of the PC board.
3. After the PC board is installed, peel off the surface (double-sided) protective film within one week.
4. If you need to punch holes directly on the PC board during installation, the general aperture must be greater than 50% of the bolt diameter. Bolts with a head larger than the aperture should be used and a waterproof pad should be added.
5, the bolts should not be too tight during installation, otherwise it will cause PC board burst and waterproof problems.
6. The addition of DOP plasticizer in PVC gasket and the chemical substances in some rubber gaskets will damage the PC board after contact with the PC board, so it is absolutely unusable. It is recommended to use the material of the gasket as EPDM rubber (EPDM). , Silicone rubber and Neoprene rubber. If you don't have a suitable gasket, you'd rather not use it, otherwise it will damage the PC board and cause it to break.
7, need to seal the rubber installation, you can use neutral Silicone (silicon) neutral series sealant (alcohol type, Toshiba) or double-sided waterproof tape.
8. Double-sided waterproof tape can be used for gasketing between sheet and frame, in addition to waterproofing. Most double-sided tapes are destructive to PC boards. Therefore, it is necessary to select a tape that does not damage the PC board, such as Japanese butyl waterproof tape.
9. If the PC board needs to be bent, its construction bending radius should be larger than the strain bending rate radius. The strain bending rate radius is as follows:
The bending radius (R) of the 1PC endurance board (solid board) needs to exceed 180 times the thickness of the board.
10, PC board has a protective film on both sides, anti-UV treatment surface protective film has a printed logo, this face is facing the sun when installed.
