Product introduction:
HDPE Strong cross film self-adhesive Waterproof roll It is a special cross laminated high-density polymer ethylene (HDPE) Strong film and high-quality polymer self-adhesive rubber asphalt The high-performance, cold construction self-adhesive waterproof coiled material compounded by special process has good dimensional stability, thermal stability, direct light prevention performance and two-way tear resistance.
The strong cross film used in this product is the height formed by cross lamination HDPE Membrane, the longitudinal and transverse elongation of the membrane made by this process is the same, the coiled material will not deform, and it is more beautiful and waterproof effect is more reliable.
The use of high-quality pressure-sensitive reaction self-adhesive adhesive layer can quickly combine with the concrete base, and its good self-healing performance and local self-locking performance greatly reduce the leakage probability. High molecular polymer (chain segment) and cement Hydrate (silicate network) forms (interface) interpenetrating network structure, and finally forms continuous mechanical bonding, which is sealed on cement cementitious material components.
Product features:
one The tear strength and water tightness of the nail bar are better than the ordinary mask.
two The self-adhesive waterproof coiled material produced with strong cross film has a stronger grip on nails and other roof fasteners than ordinary waterproof coiled materials, and has a slightly higher tear. Because when a nail passes through a strong cross membrane, the crisscross membrane has a wrapping effect on the nail, and the force is consistent in all directions, so it is not easy to tear. While ordinary films have higher longitudinal strength, the transverse strength will be very low.
three Good tensile strength, two-way tear resistance and weather resistance.
four Good dimensional stability, no wrinkling, and more reliable waterproof effect.
Scope of application:
HDPE Strong cross membrane self-adhesive waterproof coiled material is used for non exposed roof, underground waterproof works, as well as open cut subway, tunnel, pool, canal and other projects, especially for projects where open fire is not allowed; Cement mortar shall be used for bonding with the base course, and self-adhesive bonding shall be adopted between coiled materials.
matters needing attention:
one During the construction of dry paving method, the base course shall be flat and dry, and the base course shall be treated with special base course treatment agent.
two When the wet paving method is used for construction, the air of the coiled material must be driven out, and the coiled material and cement gel must be fully adhered by the pressure roller. The waterproof layer of the coiled material after construction is strictly prohibited to tread. After the waterproof layer of coiled material is accepted, it should be protected as soon as possible to avoid exposure and physical damage.
three For the damaged part, the surface of the damaged part must be cleaned and repaired with self-adhesive coiled material, and the lap width with the surrounding area shall not be less than one hundred Mm.
