SAM-980 wet-laid adhesive polymer modified bitumen membrane I. Introduction and Product Caption 1 Introduction SAM-980 wet-laid adhesive polymer modified bitumen membrane is a non-woven polyester fiber base for the child, both sides are coated with adhesive asphalt, the lower surface of the silicon to increase recoating isolation membrane, polyethylene film, fine sand and other insulating material, the surface covered with silicon coated release film or coated silicon release paper as a separator material into a wet-laid process applies to the construction of self-adhesive waterproofing membrane. Implementation of the standards: GB / T 23457-2009 "pre-shop / wet-laid waterproofing membrane." 2. Product caption Second, classification, size 1, Category: Press on the surface of the material can be divided into three non-film, polyethylene film, and fine sand and so on. 2, according to the bonding surface is divided into one-sided adhesive (S) and double-sided adhesive (D) three. 3, according to the performance of the product is divided into type I and type II. Third, the product features a high polyester tire tensile strength, elongation greater resistance, tear resistance and Kepo relatively strong stretch marks on the surface of the substrate deformation and cracking adaptability; 2, bonding good performance, high bond strength with cement mortar; 3, and building grassroots automatic bonding with cement mortar, without primer, hot melt, no fire hazards, you can not deal specifically on the uneven grass-roots level, the construction is simple, safe and environmentally friendly. 4, with cement mortar and a variety of materials as the bonding material, anti-destruction capability, with excellent waterproof function, effectively prevent liquid water and water vapor into the structure; Fourth, the scope 1, SAM-980 wet-laid adhesive polymerization modified bitumen membrane material is suitable for all types of building non-exposed roof, underground and indoor projects, open-cut subway, tunnel, ponds, canals and other water projects, especially projects are not allowed to use open flame apply. Fourth, the scope 1, SAM-980 wet-laid adhesive polymer modified bitumen membrane is suitable for all types of building non-exposed roof, underground and indoor projects, open-cut subway, tunnel, ponds, canals and other water projects, In particular, more and more applicable to the project are not allowed to use open flame. Fifth, the construction process A, a waterproofing membrane pre-shop, the base surface must be dry, clean and free of clear water. 2, the floating dust, debris clean up some of the pitfalls of the local leveling to be trimmed. 3. Brushing primary treatment agent can be used, even brushing, do not open at the end does not accumulate. 4, the coil structure for self-adhesive release paper, PE film side down, in a comprehensive pre-laying underground engineering concrete pad, floor mat and maintenance on the structure. 5, the Stones roll should be smooth straight first lap accurate size, membrane below the air should be excluded as possible, with a round flat roll compaction. 6, two adjacent coils can overlap seams way, torn seams with self-adhesive side of the reserve isolated directly paste form 7, thrown off the release paper, steel banding directly without having to pre-shop roll protective layer of mortar or concrete pouring on the timber. The self-adhesive membrane closely adhered to the main structure of concrete, fully filled paste. B, a wet-laid waterproofing membrane, waterproof construction began before the projections should eradicate the grassroots and at the same time to clean up. 2, the primary advance to maintain adequate moisture, then wipe the grout spread, such as base flatness poor cement mortar can be processed; the construction of a dry shop law, can be painted directly on top of the dry grass-roots primary treatment agent after paving. 3, cut sheet, get under the lower surface of the insulating film roll. 4, the coil slowly roll spread on the cement mortar. 5. Remember that the exhaust air coil underneath, while the adjacent edges overlapping web firm paste. Six construction drawings
