PSA cross-reactive adhesive wet-laid waterproofing membrane price I. Introduction and Introduction 1 Introduction PSA cross-reactive adhesive film is wet-laid waterproofing wet construction process, and mixed in situ concrete or cement mortar Bonded strong cross-reactive polymer adhesive waterproofing membrane. Add only active agent in self-adhesive, floods, etc., while maintaining the advantages of increased glial creep, penetrate into the traditional self-adhesive rubber base concrete holes and capillaries on the form and function of physical adsorption of mortise and tenon, The waterproof sealing layer, concrete and cement also occurs a chemical reaction with the gel, chemically crosslinked structure is formed, so that a strong bond with the primary coil to form a seal. 2. Introduction Figure II, Categories 1, by one-sided adhesive surface (S), double-sided adhesive (D) of points, based on the performance of the Ⅰ and type Ⅱ. 2. Product Specifications Coil Full thickness: Speed ??(S): 1.2 mm, 1.5 mm 2.0 mm; double-sided pressure-sensitive adhesive (D): 1.5 毫米 2.0 mm. Ⅰ type filling needs to select a strong crossover film or polyester film; Ⅱ type group is a powerful cross membranes. 3, the product label store codenamed wet (W), water (P). 20 m 2.0 mm double-sided adhesive PSA-228Ⅰ type reaction cross sticky wet-laid waterproofing membrane labeled: WˉˉPⅠS2.0 mm 20 m GB / T 23457-2009 4, the implementation of standards GB / T 23457-2009 "pre-shop / wet-laid . waterproofing membrane "three, PSA response sticky wet-laid cross membrane waterproofing Features Specifications: 1.2mm 1.5mm, 2.0mm thickness of 1.2mm, 1.5mm, 2.0mm Weight: 45kg Others: single, double, Ⅰ type, Ⅱ type, wet-laid, pre-coated, wet-laid process, wet laid type, pre-shop law, the pre-laying ceremony of the polymer matrix material is a cross superimposed by a high-density polyethylene film. 45 ° oblique cut of the film cross-monolayer films are stacked, multilayers said. Unlike ordinary due to the strong cross-laminated monolayer or multilayer film structure, and ordinary film does not have thermal stability, dimensional stability, bidirectional tear resistance, high strength and high elongation. ● with excellent dimensional stability. Can be well fixed size itself is not deformed. ● Bi-directional tear resistance. Vertical and horizontal network structure effectively easily from the construction of the phenomenon, wrinkled drum resolved. ● has UV resistance. Maintenance and use high-temperature outdoor conditions. ● has high strength and high elongation. Excellent high temperature performance. ● has a unique puncture resistance. Watertight handle excellent waterproof performance better than ordinary. Direct glue evenly prime grout in the base layer (3 5mm thick?), Bonds and rear self-adhesive surface of the film torn off film for grass-roots self-adhesive membrane surface transition, and transition: Fourth, the construction method of a wet-laid process stick with the adhesive layer. When the front structure, may be accompanied by a number of special plastic in the slurry to increase the viscosity of the slurry. 2. grassroots cleanup process → damp substrates (such as grass-roots moist without this step) → positioning, playing wipe grout line →→→ shop self-adhesive waterproofing membrane on the membrane surface beat, dry place to mention pulp → 24 hours, 48 ??hours, a coil → close to the head, sealing → trim, acceptance. 3, the operating point of the primary treatment: surface treatment should be done first, PSA response cross stick waterproofing membrane wet-laid solid grass-roots level, clean, fully wet, no water. Su preparation Filling: 42.5 cement: water = 2: 1, based on the amount of the base surface and weather conditions can be properly adjusted water, remove the soaked surface is more dilute laitance, then stir motor. Concrete and mortar: according to the site base flatness in order to determine the thickness of the grout clean shop, usually 3 5mm, wipe should pay attention compacted mat, smooth?. Wipe mortar range is not too large, while wiping edge shop. Rolling Stone: before the next self-adhesive membrane, tile cement mortar film Stones roll, torn upper surface of the insulating material. Ishinomaki after the first complete, add a touch of water, mud, laid a second site, and so on. Tapping the membrane surface, mention pulp: wood trowel or rubber sheet flutter in the web surface, a lower surface lift pulp, coil discharge air, so closely bonded membrane and cement mortar. Dry place: dry 24-48 hours (depending on the specific time depending on the ambient temperature), under normal circumstances, the time required, the higher the temperature, the shorter. Five, PSA cross-reactive adhesive wet-laid waterproofing membrane Precautions ● rain, snow, the weather may not be more than five wind Stones roll; ● construction adhesive surface should be clean lap; ● direct bonding at low temperatures The method of construction, sheet lap construction site should assist hot air. Sixth, the application is suitable for basements, subways, tunnels, swimming pools, roofing, underground garage roof green roof garden planting and other water projects. Seven, packaging, storage Packaging: Special packaging films, plastic packing tape roll, the plastic heat ends together. Storage: Storage temperature should be no higher than 45 ℃, one-year storage period. Transportation: lying horizontal, the height shall not exceed five, prohibit cross-layer, to prevent the sun and rain. Eight, the production base Niu Xugong Zhang Publisher
