PET polyester composite self-adhesive waterproofing membrane price I. Introduction and Introduction Figure 1. Description PET polyester composite self-adhesive waterproofing membrane is fully waterproof materials research and development of existing, according to the new requirements of the modern work with waterproof The first part of the basis of technical performance line of polymer waterproof material products on the - on-chip products and the group has acquired PET-based waterproof layer polyethylene layer, then double-sided non-woven composite fabric, made of waterproof material The new structure of the reinforcement layer. The product's creativity will be greater than PET material, 9 times the tensile strength of polyethylene as the main waterproof layer waterproof membrane, it has excellent physical and mechanical properties, and significantly improve the tensile strength, heat aging retention rate. PET than polyethylene O 2 CO 2 anti-infiltration rate of small hundredfold reinforced composite waterproofing membrane functions and expand the range of products, PET itself has a strong UV resistance and high temperature performance, and additives, a double protection to extend the plate life. The product is non-toxic, harmless, non-polluting synthetic polymer materials, processing waterproof membrane made of a green building materials. The structure of the product, there is no screed layer (layer) of special requirements on moisture content, as long as there is no reliable water construction and engineering quality. 2. Introduction Figure II, PET polyester composite self-adhesive waterproofing membrane features introduced 1, PET polyester composite waterproofing membrane and wet construction methods in the construction waterproof material production and construction of a new breakthrough technology, it has a large number of the Examples basement, roof, foundation and other water projects to use, construction of environmental protection. Today its promotion and application of water will have a profound impact on the entire construction sector. 2, wet dedicated PET polyester composite waterproof membrane is a polyester film (aluminum, plastic composite), self-adhesive materials and isolation material in thicknesses generally used 1.0 mm 1.2 mm 1.5 mm, its unique material properties of wet construction The method allows to maintain long-term stable long waterproof effect, generally up to 20 years. Three, PET polyester composite self-adhesive waterproofing membrane and clean grassroots acceptance procedures (leveling layer) - adhesive formulation (and used in the preparation) - dealing with complex parts (yin and yang angle, cornice, the water, the pipeline hole, and other parts) of an additional layer - Construction of waterproof layer - waterproof layer tests - a protective layer construction inspection Fourth, the construction job requirements (1) primary paving waterproofing membrane surface (screed) must be cleaned and sprinklers guarantee grass-roots moist. (Note: The roof screed should comply with GB50207-94 "roof project specification underground waterproof leveling layer shall comply GBJ208-83 underground waterproof construction and acceptance" provisions). (2) containing 10% -15% polyethylene rubber cement paste prepared cement binder weight, and stirred to be uniform, no precipitation, no clot, no segregation can be used. (3) Roof Main waterproof layer construction, should be focused on the complexity of the film and an additional layer to seal the deal and the main waterproof layer membrane material to the detail section of drainage and structures. (4) polyether polyurethane sealing material, such as the use of other sealing material should be free of other chemicals in mineral oil, petrolatum and polyethylene products affect performance. (5) should be laid at the corner of an additional layer; Yang angle, etc., are R = 20 毫米 rounded. (6) The waterproofing membrane should be paved paving method, adhesive coating the surface of base should be uniform, not open at the end, do not build up; adhesive coating should immediately Stones film to prevent prolonged affect the bond quality. (7) Paving waterproof membrane, should not wrinkle, can not force the stretch film, and pave the way for an edge exclusion of the following coil air and excess adhesive and ensure the film and the main surface of the adhesion between the layers of the film. (8) Paving waterproofing membrane lap width should be no less than 100mm. (9) the upper and lower membranes of two adjacent joints should be staggered by a third the size.
