Features of 1.5mm expansion waterproof board hot-melt gasket:
a. Swelling performance in case of water. When water penetrates into the gap where the waterstop has been embedded, it will expand, block the seepage gap, cut off the seepage channel, prevent leakage, and have good seepage resistance effect.
b. It has good overall expansibility, no disintegration, good erosion resistance, good compression elasticity, slow expansion speed, large expansion potential, strong water pressure resistance, and the impedance can be ≥ 2.5Mpa.
c. It can be used for projects with abundant construction water and projects constructed in rainy season. The main material is inorganic mineral material, so the aging resistance, corrosion resistance, and impermeability are not affected by the alternate changes of temperature, and have reliable durability.
d. Non sticky, easy to install and use, and moderate price.
Characteristics of hdpe tunnel geomembrane hot-melt gasket:
a. The chlorinated butyl rubber with aging resistance and water resistance is selected as the main material, supplemented by its specific materials, which has reliable durability;
b. It has self adhesion and can be lapped by its own adhesive force;
c. The inorganic water absorbent is closely combined with other materials by special processing technology;
d. With plasticity, it can be produced according to user requirements;
e. The material does not contain any heavy metal salts and toxic substances, and does not pollute the environment;
Although it is not often seen in our life, it plays an important role. This kind of accessories is made of high temperature injection polymer material (polyethylene), which is made by a special mold and has a certain specification of hot-melt round gaskets for waterproof boards. This kind of gasket product is widely used in water conservancy, roads, tunnels, waterproof coiled materials, geotextile installation and fixation due to its light quality, strong adaptability, convenient installation and not easy to damage the performance of waterproof boards. Products, hot melt gaskets for waterproof boards are in increasing demand in the market and occupy a higher position in the project.
Hot melt gaskets are mainly used for welding waterproof boards in highway tunnels. The hot-melt gasket is used for the film hanging and positioning of the tunnel waterproof board. The material is made of imported plastic injection molding, which can better integrate the welding of PE, PVC, EVA and other hot-melt materials. The company's product features strong adaptability, and the mix ratio of raw materials is flexible, which can match with various types of waterproof boards produced by major waterproof board manufacturers. Welcome the construction units and dealers to call for advice!

The hot-melt gasket is a hot-melt gasket (ring) with certain specifications for tunnel waterproof board made of high injection molded polyethylene through a special mold.
Hot melt gaskets are mainly used for welding waterproof boards in highway tunnels. The company has strong adaptability to product characteristics and flexible mix proportion of raw materials.
Installation instructions:
1. Constructor: be responsible for guiding the construction team according to the design requirements;
Technical director: adjust operation methods according to design requirements and construction conditions. Guidance, inspection and construction;
Quality inspector: check the construction quality according to the design requirements.
2. Construction tools: hot air welding plastic device, nail shooting rod, nail shooting, hammer and other tools with large power not less than 2 kW.
Installation: The hot-melt gasket shall be installed in quincunx shape. The vertical spacing shall not be more than 80cm, each roll of waterproof board in the horizontal direction shall not be less than 3, and the vertical and horizontal spacing at the top of the tunnel shall be less than 50cm. When installing the hot-melt gasket, fix the geotextile vertically and horizontally with the nail on the tunnel excavation face. If there is a bulge at the end of the steel nail, use a hammer to flatten it, so as to ensure that no protruding steel nail pierces the waterproof board. After the geotextile is fixed by the hot-melt gasket, 3 to 5 operators shall start to lay the waterproof board. When welding the hot-melt gasket, hot air plastic welding rods shall be used on both sides of the waterproof board to heat weld on the back of the waterproof board one by one from the bottom to the top clockwise or counterclockwise. At this time, the construction workers shall stick the waterproof board and the hot-melt gasket at an angle of 45 ° and rub them with hands outside the waterproof board to make them fully fused. During welding on the top, two operators shall hold the waterproof board and cool it with wet cloth to avoid falling of the waterproof board when it is not cooled.
