TPO waterproof membrane manufacturers will show you: What are the classifications of waterproof membranes

The manufacturer of TPO waterproof membrane tells you that the waterproof membrane requires good water resistance and stability to temperature changes (no flow, no foaming, no movement at high temperatures; no brittleness at low temperatures), a certain degree of mechanical strength, ductility and resistance to breakage Sex, a certain degree of flexibility and aging resistance. The manufacturer of TPO waterproof membrane tells you that the waterproof membrane is a membrane waterproof material. It is one of the important varieties of waterproof materials for construction projects.

(1) Asphalt waterproof membrane: The manufacturer of TPO waterproof membrane tells you that asphalt waterproof membrane refers to the membrane with tires and the membrane without tires. All rolled materials made of thick paper or glass fiber cloth, asbestos cloth, and cotton and linen fabric impregnated with petroleum asphalt are called tire steel coils; asbestos, rubber powder, etc. It is mixed into bituminous material, and this rolled material is called rolled coil, that is, tireless coil.
(2) Polymer modified bitumen waterproof membrane: The manufacturer of TPO waterproof membrane tells you that polymer modified bitumen waterproof membrane uses modified bitumen as the membrane impregnating material. Ordinary petroleum asphalt materials tend to become hard, brittle, and crack at low temperatures, and have strong temperature sensitivity. Under the action of the sun's long-term ultraviolet rays, they soften at the high temperature in summer, causing pyrolysis and flow. Repeated thermal expansion and contraction will cause changes in the internal stress of the asphalt. Under the combined action of oxygen and ozone, the chemical composition in asphalt is constantly changing. First of all, the oil volatilizes, the asphalt mortar content decreases, the plasticity decreases, the brittleness increases, the cohesive force decreases, cracks and aging appear. The manufacturer of TPO waterproof membrane tells you that due to these reasons, traditional petroleum asphalt waterproof materials can no longer meet the needs of building waterproof and durable life. Adding a certain amount of polymer modifier to asphalt can improve the inherent low temperature brittleness and high temperature fluidity of asphalt. Modified asphalt not only has good high and low temperature performance, but also has good elasticity, plasticity, hydrophobicity and cohesiveness. Compared with asphalt, polymer-modified asphalt waterproofing membrane has higher tensile strength, heat resistance and low temperature flexibility, and has better water permeability and corrosion resistance.
(3) Synthetic polymer waterproof membrane: The manufacturer of TPO waterproof membrane tells you to use synthetic rubber, synthetic resin or their blends as the base material, and add appropriate chemical additives and fillers. The crimpable sheet-like waterproof material processed by different processes; or the above-mentioned materials are combined with synthetic fibers to form two or more layers of crimpable sheet-like waterproof material. The manufacturer of TPO waterproof membrane tells you that its high material index, such as excellent elasticity and tensile strength, enhances the adaptability of the coil to the deformation of the base layer; excellent weather resistance can extend the service life of the coil under normal maintenance conditions, reduce maintenance and refurbishment cost.
TPO waterproof membrane manufacturers tell you that waterproof membranes are mainly used for engineering construction, such as roofs, exterior walls, basements, etc. The waterproof material products made by impregnating asphalt or polymer waterproof material on the substrate are provided in the form of coiled materials, called waterproof coiled materials. According to the main constituent materials, they are divided into asphalt waterproof coiled materials, polymer modified bitumen waterproofing coiled materials and Synthetic polymer waterproof membrane.
