Waterproof roll Mainly used for building wall , roof, tunnel, highway, landfill, etc be launched A kind of flexible building material product that can be rolled into a roll, as a non leakage connection between the project foundation and the building, is the waterproof barrier of the whole project and plays a vital role in the whole project.
The main products are asphalt Waterproof roll and polymer waterproof roll.
Waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of coiled materials, which are called waterproof coiled materials. According to different main components, it can be divided into asphalt waterproof coiled material, polymer modified asphalt waterproof coiled material and synthetic polymer waterproof coiled material; It can be divided into carcass free coiled material, paper tire coiled material Glass Fiber tire coiled material, glass cloth tire coiled material and polyethylene tire coiled material.
Waterproof coiled materials are required to have good water resistance, stability to temperature changes (no flowing, bubbling, stirring under high temperature; no embrittlement under low temperature), certain mechanical strength, extensibility, fracture resistance, flexibility and aging relief.
Waterproof coiled material is a kind of sheet waterproof material that can be rolled. It is one of the important varieties of waterproof materials for construction projects. According to its main waterproof components, it can be divided into asphalt waterproof materials, polymer modified waterproof coiled materials and synthetic polymer waterproof coiled materials (SBC120 polyethylene polypropylene fiber composite coiled materials). There are PVC, EVA, PE, ECB and other waterproof coiled materials
Asphalt waterproof coiled material is a kind of coiled sheet waterproof material made by dipping asphalt on the substrate (such as base paper, fiber fabric) and then spreading powdery or sheet isolation materials on the surface.
1. Water resistance
Water resistance means that its performance is basically unchanged under the action of water and after being soaked by water, and it is impermeable under the action of pressure water. It is usually expressed by indicators such as impermeability and water absorption.
2. Temperature stability
Temperature stability refers to the performance of no flowing, no foaming, no sliding at high temperature, and no embrittlement at low temperature, that is, the ability to maintain the original performance under certain temperature changes. It is usually indicated by heat resistance, heat resistance and other indicators.
