Pre shop / wet lay-adhesive polymer modified bitumen membrane I. Introduction pre-shop / wet lay-adhesive polymer modified bitumen membrane is a non-woven polyester fiber base for the child, coated on both sides with quality synthetic rubber, heavy traffic bitumen, coated silicon surface covered under isolation film, polyethylene film, fine sand and other insulating material, the surface covered with silicon coated release film or coated silicon release paper as a separator made of a material suitable for wet-laid process Construction of self-adhesive waterproofing membrane; the implementation of national standards GB / T 23457-2009 "pre-shop / wet-laid waterproofing membrane." Second, product characteristics (1), can be directly in the wet construction (no clear water) base surface. (2), and cement-based adhesive uncured surface, eliminating the screed, and work together to build a solid structure waterproof system. (3), very unique "self-healing" feature. (4), a strong primary bonding forces, the web may be damaged due to leakage caused by limitations in the local area, to prevent the failure of the waterproof layer as a whole. (5), polyester tire high tensile strength, elongation greater resistance, tear resistance and Kepo strong grass-roots stretching and cracking deformation adaptability. (6), pre-shop / wet lay-adhesive polymer modified bitumen membrane and building grass-roots filled with cement mortar adhesion without primer, hot melt, no fire hazards, without the need for specialized treatment uneven grassroots, simple construction , safety and environmental protection. Third, the scope (1), all kinds of underground engineering water impermeability, such as basements, air defense projects, subway and other water projects. (2), industrial and civil engineering roof and exterior waterproofing. (3), is quite sensitive to moisture grain storage, electronics shop, etc. moisture, waterproofing. (4), coastal areas have water corrosion Engineering seawater corrosion and deformation of parts of larger structures. Fourth, note pre-shop / wet lay-adhesive polymer modified bitumen membrane packaging - plastic packaging tape rolls. Storage and transport - should avoid rain and sun, pay attention to ventilation, storage temperature not higher than 45 ℃, stand up storing only a single layer, transport neutral place not more than two, to prevent skewed or horizontal pressure during transport. Construction - the ambient temperature is low or the local stress is large, can make use of the product during use liquefied petroleum gas, ethanol fuel or electric heating welding; construction method using hot melt material surface temperature should not be higher than 200 ℃.
