Brief introduction of flexible waterproof material
Flexible waterproof materials, mostly organic materials such as asphalt and linoleum, also known as linoleum coiled material waterproof layer, are coiled materials made of fiber fabrics such as linoleum and glass cloth, and bonded to the leveling layer on the roof structure board with various cementing materials such as asphalt. Flexible waterproof materials have high tensile strength, large elongation, light weight and convenient construction, but the technical requirements for operation are stricter, and the puncture resistance and aging resistance are not as good as those of rigid materials, so they are easy to age and have short service life.
What flexible waterproof materials are there?
Flexible waterproofing blocks the passage of water through flexible waterproof materials (such as coiled material waterproofing and coated film waterproofing), so as to achieve the purpose of building waterproofing or increase the anti-leakage ability. The most widely used flexible waterproofing material is SBC 120 polyethylene polypropylene composite waterproofing membrane.
Building waterproof materials are available from petroleum asphalt linoleum? /kloc-with a history of 0/30 years, how many types of waterproofing membrane products are available in the world today? Tire-based petroleum asphalt felt, synthetic polymer modified asphalt coiled material, synthetic polymer sheet. Synthetic polymer plates are divided into rubber and plastic, and also into uniform cross-section and reinforcement. Usually, the reinforcement is an internal reinforcement structure to make up for the lack of tensile strength of materials. It is difficult to combine the smooth surface of materials with the surface of building structures characterized by cement firmly and stably. When the water content is higher than. 9%, the bonding effect is greatly reduced. It is more difficult to rebuild the concrete structure on the surface of the constructed coiled material.
In order to stabilize the waterproof engineering structure, it is necessary to bond the surface of waterproof coiled material with cement material directly to obtain a stable waterproof structure and facilitate construction. Polyethylene polypropylene double-sided composite waterproofing membrane with rough surface. This technology was patented in China on 1992, and has been widely used in construction, water conservancy, chemical industry and environmental protection projects, with an annual application of more than 3 million cubic meters, and achieved good engineering application results.
Application advantages of flexible waterproof materials
1) solves the problem that most organic waterproof coiled materials cannot be directly bonded with cement materials;
2) There is no requirement for the construction of most organic waterproofing membrane products with low moisture content at the building base (
3) The problem that the main waterproof material of the organic waterproof coiled material is easy to be damaged and aged when exposed is solved;
4) There are no problems such as open flame construction and environmental pollution caused by some waterproof coiled materials;
5) The waterproof system gets rid of the method of solely relying on waterproof materials to undertake all waterproof functions, which reduces the consumption of organic materials and engineering costs and improves the waterproof effect.
What are the flexible waterproof materials? What kind of materials are flexible waterproof materials? What are the advantages of flexible waterproof materials? These small series have been introduced in detail. There are many kinds of flexible waterproof materials, mainly the combination of different organic substances and different kinds of colloidal substances, which show different characteristics. Although the anti-aging ability of flexible waterproof materials is weak, the use effect is still good. It is recommended that you use flexible waterproof materials.
