How to effectively waterproof steel plate

Color steel plate refers to the color coated steel plate, is a kind of organic coating with steel plate. The color steel sheet is a cold-rolled steel sheet, a galvanized steel sheet, a surface-treated product (roll coating) or a composite organic film (PVC film, etc.) and then cured by baking. Color steel plate as a major material in the construction industry, with the progress of science and technology, environmental awareness, the improvement of people's living standards, color steel plate more and more shows a strong vitality and broad market prospects, by the construction, home appliances, , Transportation, interior decoration, office equipment and other industries of all ages. It is simple and convenient, speeding up the construction to speed up the pace for the project to improve efficiency. But if the phenomenon of water leakage is certainly the screw and the color of the steel plate at the junction of the opening or caused by the opening.
Color plate leakage reasons:
1, roof screws and fasteners at the leak. This phenomenon is more common, mainly in double-color steel plate and single-layer steel plate roof.
2, color steel plate lap leakage. The reason is mainly between the two boards are not tight overlap, since the tapping did not play the formation of gaps and so on
3, roof tile leakage. In the construction of light steel roof, the leakage caused by the roof tile is also a more common phenomenon.
4, color steel plate effective waterproof measures:
(1) waterproof layer exposed: the use of EPDM waterproofing membrane, cold sticky construction, can not use SBS hot melt construction, will damage the insulation layer or construction may cause a fire, self-adhesive membrane weather resistance is poor, easy Ageing. EPDM waterproofing membrane anti-ultraviolet ability, cold stick construction, does not destroy the insulation board, it was listed as the preferred material.

(2) waterproof layer is not exposed: that is done in the color plate after the waterproof, waterproof layer on other materials, so that the waterproof layer is not exposed, may consider the use of acrylic waterproof coating such as JS composite waterproof coating or acrylic waterproof coating , Such materials, better weather resistance, not aging, flexibility and strength is also better.
