Polycarbonate plate installation matters needing attention

Polycarbonate vinegar PC board should be cleaned before installation of the frame, because the metal material will be left in the factory before the metal elbow oil or

Acid lotion and other chemicals. And these chemical residues can cause certain damage to the plate. Polycarbonate cool PC plate in the installation fixed to

Reserve the corresponding expansion space for the plate, because PC board in the outdoor will be affected by thermal expansion and contraction, will also produce the corresponding expansion changes.

Calculation method of expansion reserved space: linear expansion coefficient X sheet length x maximum temperature difference before and after installation, linear expansion coefficient is fixed value 0.065mm\

M, if the appropriate expansion space is not reserved, the sheet may expand due to the lack of corresponding space will cause stress extrusion, or produce

Displacement will damage the plate.

Polycarbonate vinegar PC plate installation, can not use PVC pad, because PVC gasket plasticized and some chemical gasket contained in the chemicals

The quality will be moved to the mat surface and PC board after direct contact will destroy PC board. But you can use gasket material calendar for EPDM if

If you cannot find a suitable gasket, you would rather not use it than use a PVC pad roll. Polycarbonate vinegar PC plate installation sealing, to use neutral silicon system

Column sealant, rubber laminate, double - sided waterproof adhesive. Polycarbonate vinegar P plate for cutting the best saw blade for carbonization dock material.

The sheet should be fixed when cutting to prevent excessive vibration. Polycarbonate vinegar PC board is easy to scratch, so in storage, handling, cutting

Do not remove all the protective film. And when cutting in the plate to mark the pen, it is best to use crayons, avoid sharp items directly connected

Touch the plate. Polymagnetic acid cool PC board is strictly prohibited from direct contact with the cement, the alkaline substance in cement for the destruction of the board. poly

Carbonated vinegar PC board in the use of bending, the construction radius should be greater than the allowable radius of curvature, the allowable curvature calculation method is; When PC board

In outdoor use when allowed curvature calculation method :(R) more than 180 times the thickness of the plate such as :4mm thick PC board for outdoor bending, the allowed curvature is :4x720=180mm, so the outdoor design of the radius of curvature (R) at least in 72cm above. When PC boards are used indoors,

Allowable curvature calculation method :(R) plate thickness of more than 150 times, such as :4mm thick PC plate used for indoor bending, its allowable curvature is :4x

600=150mm so interior design radius (R) should be at least 60cm above. PC board in bending use, PC board minimum bending half

If the diameter is not reached, it will make the plate in the bending of the extrusion stress is not uniform or increase the pressure stress, thus affecting the normal plate

The service life is likely to cause the plate to fracture due to local stress increase.

Polycarbonate cool PC board in cleaning, when there is dirt on the surface of PC, to the first soft cloth and sponge with neutral detergent rub report, and then clear

Water for rinsing. Finally wipe thousands with a soft cloth. When the solvent is used to clean the sheet, the pair contains toluene, gasoline, carbon tetrachloride, and propylene

Medicine and other components of the solvent will cause damage to the plate, must not be used. Alcohol such as alcohol, isopropyl alcohol can be used. Polycarbonate vinegar PC board

When the screw is tight, the spacing of the screws can be adjusted according to the thickness of the plate. If the spacing of the screws is too dense, it may cause

The increase of stress on the sheet causes the failure of the sheet. The spacing of screws is too sparse, which may cause the plate to be fixed unstable. Screws are specially made according to common specifications

Spacing is summarized as follows: for plate thickness below 3mm, screw fixing spacing is about 20-10cm; for plate thickness above 3mm, screw fixing spacing is about

30-20cm, if fixed with laminating, screw fixing spacing is about 30-20cm if the use of self-tapping screws directly fixed PC plate, the greater the spacing,

The more the plate will not be damaged by stress. The screw hole, the eye should take into account the thermal expansion and cold contraction of the plate, the screw aperture is larger than the direct screw

Some, between 2mm and 4mm. The position of the screw hole must not be too close to the edge of the plate, which is easy to cause the plate to break, generally speaking

The distance between the wire hole and the edge of the plate is more than 2.5 times the diameter of the screw.
