[2023/03/29]Where is HDPE polymer self-adhesive film waterproof coil suitable for? |
HDPE polymer self-adhesive film waterproof coil is a kind of multi-layer composite waterproof material with superior performance, which is developed specifically for the engineering site which needs to be constructed by prelaying method in underground engineering. It is mainly composed of modified high density polyethylene (HDPE) as the base material and thermal composite with non-asphalt based polymer self-adhesive layer. The isolation layer is a new polymer waterproof coil made of sand or aging resistant polyethylene silicone oil film with special properties. Before the initial setting of the post-cast concrete, the concrete slowly crosslinks with the self-adhesive layer of the coil under the action of gravity, resulting in physical adsorption and mortise and tenon in the cement curing process, so that the coil cup is firmly bonded to the post-cast concrete and is not easy to get off.
Product characteristics
1. When concrete is poured, the cement slurry reacts with the special polymer wet curing of the coil bonding layer, forming a permanent organic bond between the coil and the structural layer on the coagulation, forming a no-gap structure and eliminating the phenomenon of curtain water; Even if the coil local damage, will also be limited to a small range of water, completely improve the reliability of the waterproof layer.
2, the use of single layer to meet the underground waterproof engineering level waterproof fortification requirements, no need to do protective layer, the comprehensive cost can be reduced by 50%.
3, strong chemical corrosion resistance, impact resistance and puncture performance is excellent, can withstand the impact of direct action on the construction load and steel skeleton, do not need cement mortar protective layer, direct implementation of reinforced concrete pouring, thus greatly shorten the construction period, reduce the cost.
4, self-adhesive pressure sensitive adhesive layer, strong self-healing, never curing.
5, convenient and efficient construction: wet construction, not affected by weather and wet base. No leveling layer without bottom oil without base baking, rainy season construction and rush project has its unique obvious advantages.
6, cold operation, no open flame, non-toxic tasteless, no environmental pollution and fire hazards, safety and environmental protection.
7, maintenance is very convenient and fast.
Scope of application
In the 1970s, with the continuous development of global economic construction and the rapid rise of the construction industry, the demand for waterproof coil was further raised. Therefore, manufacturers tried to add high polymerization SBS or APP modifier into asphalt to improve the high and low temperature performance and durability of waterproof coil.
HDPE polymer waterproof coil and pre-laid anti stick application technology, the earliest in the United States, Europe (Italy), Russia has the production and application. It was introduced into China by an American company in the 1990s, and has been praised by the design, construction and construction of the subway. With the expansion of the building scale, the change of the building structure, especially the increase of high-rise buildings, the traditional building waterproof material can not meet the needs of the project, so that the polymer waterproof material and its prelaying anti-adhesive technology in the roof, wall, underground waterproof engineering has been applied, improve the waterproof function of the building.
HDPE polymer self-adhesive film waterproof roll can be applied to all kinds of tunnels and underground space waterproof engineering, such as: highway tunnel, railway tunnel, power tunnel, hydraulic tunnel and subway tunnel, caverns and other structures and the use of external prevention and internal paste method of construction of underground space.
