Flexible waterproofing materials are a type of material that is mainly composed of organic materials and glue substances. This type of material has excellent ductility and can show very good performance when used for roof waterproofing. The biggest advantage is simple operation, practical and convenient. Flexible waterproof materials are now mainly used for roof waterproofing. The editor below will introduce to you what flexible waterproof materials are, what kind of materials they are, and what are the application advantages of flexible waterproof materials.
Introduction to flexible waterproof materials
Flexible waterproof materials are mostly organic materials such as asphalt and linoleum. They are also called linoleum roll waterproofing layers. They are made of linoleum, glass cloth and other fiber fabrics. The membrane of the tire layer is a waterproof layer formed by bonding the membrane to the leveling layer on the roof structural plate using various cementing materials, asphalt, etc. Flexible waterproof materials have high tensile strength, high elongation, light weight, and easy construction, but have strict operating technical requirements. Their puncture resistance and aging resistance are not as good as rigid materials, and they are prone to aging and have a short lifespan.
What are the flexible waterproofing materials?
Flexible waterproofing uses flexible waterproofing materials (such as membrane waterproofing, film waterproofing) to block the passage of water to achieve the purpose of building waterproofing or increase the number of Resistance to leakage. The most widely used flexible waterproof material is SBC120 polyethylene polypropylene composite waterproof membrane.
Building waterproofing materials have a history of more than 130 years since petroleum asphalt linoleum. The waterproofing membrane products available in the world today have been divided into several categories: tire-based petroleum asphalt linoleum, synthetic high-quality Molecularly modified asphalt membranes and synthetic polymer sheets. Synthetic polymer sheets are divided into two categories: rubber and plastic, and further divided into two categories: uniform cross-section and reinforcement. Usually the reinforcement is an internal reinforcement structure to make up for the lack of tensile strength of the material. The smooth surface of the material and the surface of the building structure characterized by cement are difficult to bond firmly and stably. When the moisture content is higher than ?9, the bonding effect is greatly reduced. It is even more difficult to construct concrete structures on the surface of already constructed membranes.
In order to stabilize the waterproof engineering structure, the surface of the waterproof membrane needs to be directly bonded to the cement material to obtain a stable waterproof structure that is easy to construct. Double-sided composite waterproof membrane made of polyethylene and polypropylene with roughened surface. This technology obtained the Chinese invention patent in 1992 and has been widely used in construction, water conservancy, chemical industry, and environmental protection projects. The annual application volume is more than 3 million square meters, and has achieved good engineering application effects.
Application advantages of flexible waterproof materials
1) Solve the problem that most organic waterproofing membranes cannot be directly bonded and laid with cement materials;
2) There is no limitation that the construction of most organic waterproofing membrane products requires low moisture content of the building base (lt; 9);
3) It solves the problem that the main waterproofing material of organic waterproofing membrane products is easily damaged and aged when exposed. problems;
4) There are no problems such as open flame construction and environmental pollution of some waterproof membranes;
5) The waterproofing system gets rid of the method of solely relying on waterproof materials to undertake all waterproof functions, reducing the It reduces the consumption of organic materials and engineering costs, and improves the waterproofing effect.
What are flexible waterproof materials, what kind of materials are flexible waterproof materials, and what are the advantages of using flexible waterproof materials? These editors have already given you a detailed explanation above. introduced. There are still many types of flexible waterproof materials, mainly different organic substances and different types of glue substances combined together to show different characteristics. Although the anti-aging ability of flexible waterproof materials is relatively weak, the use effect is good. It is recommended that you use flexible waterproof materials.
