Even the roof exposed, exposure to the sun is not a problem, polypropylene specifications, since the above is done waterproofing membrane protection layer, insulating layer, and polypropylene, rather than direct it waterproof layer is disposed in the open air; the results show: with ordinary mortar / Compared to concrete, such as adding volume content of 0.1 percent (about 0.9Kg / m3) monofilament fiber, polyethylene fiber waterproofing membrane, crack resistance mortar / concrete is increased by 70%. 2, greatly improving the impermeability of concrete. Polypropylene monofilament fiber bundle concrete 0.9Kg / m3 content than ordinary concrete impermeability capacity increased by 60% to 70%. 3, significantly improve the impact resistance and abrasion resistance of concrete roof even if exposed to sun exposure is not a problem, because the waterproofing membrane is to be done on top of the protective layer, insulating layer, rather than direct it waterproof layer is disposed in the open air ; PP _ _ PP waterproof Shouguang Tianxiang Which cheaper by Shouguang City Tianxiang waterproof material plant. _ _ Shouguang Tianxiang waterproof polypropylene PP Which is cheaper Shouguang City Tianxiang waterproof material plant (www.txfscl.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel picture on this page or to obtain the latest Information, Contact: Zhang Guang.
