Waterproof bitumen tar paper commonly known as linoleum. A waterproof material used in the construction industry. The base paper has coarse texture, good oil absorption and certain tensile strength. Generally, rags and waste paper are used as raw materials, and high-grade ones can be mixed with some animal hair and slag cotton, which can be copied after beating directly. During processing, the base paper passes through the molten asphalt and is extruded by the hot roller to make the asphalt soak the paper layer, extrude the excess asphalt, and spread talc powder or fragment Mica on the surface for cooling. Use less.
In recent years, the application of pre laid (HDPE) waterproof coiled material in underground engineering waterproof is increasing day by day. Its unique product advantages are favored by customers and users. The pre paved polymer self-adhesive membrane waterproof coiled material is composed of main material, self-adhesive, surface anti (anti adhesion) protective layer (except the lap area of coiled material) and isolation material (when necessary), which is bonded with post cast concrete to prevent water channeling on the bonding surface.
Waterproofing membrane is mainly used in building walls, roofs, tunnels, highways, landfill sites and other places. It is a flexible building material product that can be curled into rolls to resist external rainwater and groundwater leakage. As a non leakage connection between engineering foundation and buildings, it is the first barrier of the whole project waterproofing and plays a vital role in the whole project.
TPO waterproof coiled material, namely thermoplastic polyolefin waterproof coiled material, is a new type of waterproof coiled material made of thermoplastic polyolefin (TPO) synthetic resin combining ethylene propylene rubber and polypropylene with advanced polymerization technology and adding antioxidant, antioxidant and softener. It can be made into reinforced waterproof coiled material with polyester fiber mesh cloth as internal reinforcement material, It is a waterproof product of synthetic polymer waterproof coiled material.
