Since the glued seam pressure zone and its standard is what

Adhesive seam pressure with the glued seam pressure with standard production abroad since the glued seam pressure belt is generally adopt the PE film surface not tire waterproofing materials, the pulling force and the breaking elongation rate are higher, such as the United States 'will establish', its tension can be up to 25 mpa and 30 mpa, elongation of more than 300%. And domestic production in China since the glue no tire of waterproofing materials, PE film, due to the domestic production of polyethylene membrane tension is low, so in the absence of tire adhesive seam pressure with the standard stipulated in the pulling force is 130 n / 5 cm only, differ widely different. So, some important engineering required to provide the high tensile adhesive waterproof coiled material, its way has two: one is from imported high strength polyethylene film production without tire adhesive seam pressure zone; Second, the enhanced production have a tire carcass adhesive waterproof coiled material. At present, the domestic some production enterprise mostly used the technology behind this one way, since the sticky polymer modified asphalt production polyester tire waterproof coiled material, tension increase is larger, the breaking elongation decrease relatively, meet the needs of some waterproof engineering. The United States, Austria and China's Taiwan's entry adhesive seam pressure belt, there were no product standards, only product manuals, for the product size, main technical index and test method of use. It was not until 2000 that the United States finally enacted ASTMD1970 - 2000 'grassroots anti-icing plugging for inclined roofing of adhesive polymer modified asphalt coiled material', the product thickness thin, but not less than 1 mm, it is mainly used for auxiliary waterproof. Since the glued seam pressure with application in our country from the early 1990 s. In the United States when entering the market of W. R。 GRACE 'will establish ( Bituthene) 'Cold', Austria production since the glue weatherability waterproof bitumen membrane ', Taiwan's production of 'will water conservancy' and so on. These ten years, our country is part of the enterprise production and in the project on the application of this new material. Since the sticky polymer modified asphalt waterproofing materials, a kind of very promising new type of waterproof material. Just arrived at home and abroad, the ascendant. This kind of coil with impervious, low tender degree, deformation resistance and etc. , good self-healing and easy construction, can improve the laying speed, speed up the construction schedule. In guangzhou, shenzhen, nanjing, xiamen, Shanghai and other places of the industrial building roofing, underground engineering, the Antarctic Great Wall, in October, such as widely used, good waterproof effect, can be obtained by the construction, design and construction unit of praise. Although, at present the product of the market share is not big, but has become today's 'to be bestowed favor on newly' in waterproof material.
