    Features
    1. High tensile strength, high tear resistance, dimensional stability of the grass-roots deformation of strong adaptability;
      2. Anti-corrosion turbidity, mildew resistance, puncture resistance, fatigue resistance;
    3. Excellent high temperature performance, low temperature formation, hot and cold areas are applicable, excellent weather resistance;
    4. Hot melt construction joints are firm and durable.
    Applicable scope
    1. various industrial and civil construction of the roof, basement, parking and other waterproofing works;
    2. Subway, tunnel, highway bridge, landfill, sewage treatment, water canal and other municipal and water conservancy facilities waterproofing works;
    3. Large amount of expansion and contraction, easy to deformation and important parts of the waterproofing works;
    4. Logistics warehouses, temporary sheds, pipe corrosion, acid-base environment moisture-proof building waterproofing works.
    Product packaging
    The plastic tape is packed in rolls
    Transport storage
    1. Different varieties, labels, specifications and grades of the coil should be classified stacking;
    2. Avoid rain, exposure, exposure to fire, do not contaminate the dirt or grease;
    3. Standby storage and can only be a single layer, the transport process is not even more than two layers.

    Construction technology
    Hot melt method, cold sticky method and hot and cold combination method
    Coil can be used alone hot melt or cold sticky construction, can also be used hot and cold combination of large area with cold sticky method, lap joints with hot melt method for construction;
    Hot-melt method: with a flame gun or torch baking the bottom of the coil and the base surface, so that the surface of the coil asphalt melting, while baking side of the roll roll, and then use the pressure roller rolling, Material bonded firmly;
    Cold sticky method: the first adhesive evenly brushing in the waterproof base and the coil, a little dry after the film can be pasted, then press the roller, the coil under the air out, so that the coil formation, Tightly and firmly affixed to the base layer or coil.
     
    Construction machinery and accessories
    Clean up the construction of waterproof grassroots level: shovel, broom, dust collector, hand hammer, steel chisel, etc .;
    Coil paving construction tools: scissors, tape measure, bouncer box, scraper, brush, pressure roller;
    Special hot melt machine: single or long hot melt gun or torch;
    Accessories: grass-roots treatment agent, coil adhesive, closed mouth pressure.
     
    Coil
    Construction should be qualified before the acceptance of clean-up grass, the edges and corners of the dust blowing;
    Brushing the primary treatment agent should be uniform, do not repeatedly brushing;
    After the primary treatment agent is dried, the additional layer treatment should be carried out according to the design requirements for the roof waterproofing works and the underground waterproofing works.
    To determine the direction of the film paving and paving the direction and at the grass level line, and then paving the membrane, the different parts of the membrane paste the following requirements of construction;
    Roof: Coil and base point paste or paste; Roof around 800mm should be all paste; slope roof paste area of ??more than 70% between the coil and the membrane 100% full paste;
    Basement floor: the membrane and the base layer can be all sticky, sticky, sticky or empty shop, but the membrane and the membrane must be fully paste between;
    Basement wall: the web and the base and between the coil and the membrane should be fully paste;
    Additional layer: the general part of the whole paste, deformation joints allow empty shop.
    Paving order for the first high cross, after the low span; the same height, the first long after; the same plane, from the low began paving.
    Roofing direction: slope <3% parallel to the direction of the roof paving, slope 3% to 15% parallel or perpendicular to the direction of the roof paving, slope> 15% or by vibration should be perpendicular to the roof direction paving, parallel to the roof ride Seam downstream direction, perpendicular to the roof when the seam should follow the main wind paving.
     
    Construction Method of Coil Lap
    Long side lap: roll longitudinal lap width should be ≥ 80mm, must be carefully operated, brushing adhesive to be uniform, not leakage coating. Cold adhesive method should be part of the edge of the excess adhesive extrusion, hot melt method should be formed in the edge of an asphalt;
    Short side lap: Both ends of the web must be fully bonded. Lap width should be ≥ 100mm, when the polyester tire membrane sticky or empty shop, the two parts must be more than 500mm full thickness; cold sticky method: the joints should be adhesive extrusion, hot melt method: Asphalt strips are extruded;
    The same layer adjacent to the two web paving, the horizontal lap should be staggered more than 1500mm, and the upper and lower layers of the two sides prohibit the vertical paving;
    When the short side of the sheet is covered, remove the shale layer by wiping the shale with a trowel. Can also be used docking, the method is in the seam under the pad 300mm coil, the material transverse docking, seams with sealing material processing;
    After the web has been paved, the overlapped parts, ends and coils should be sealed. Should be embedded in the sealing material, sealant or cold adhesive, and then smooth, so that the formation of obvious asphalt.
