Solid PC plate bending radius to the thickness of the 175 times the same. Plate bending parts it is forbidden to use screws.
2, when installing a hollow sheet and solid PC board, the board and board juncture place, must according to the plate thermal expansion gap size reserved, thermal expansion coefficient of 0. 065 mm/m ℃, forbidden self tapping screw, rivets and other fixed directly through the plank. If must pass through, it must be on board the hole diameter is greater than the self-tapping screw rivets or 100% of the diameter of the expanded hole, drop self-drilling screw or rivet hole by expanding circle, to ensure that the plate can be adjustable freely in any direction.
3, contact with the PC board of the need for a neutral silicone sealant glue, it is forbidden to use alkaline, acid and chemical composition of unknown sealant containing solvents.
