WATERPROOFING MEMBRANE MANUFACTURER
Factors affecting the waterproof effect of sbs waterproofing membrane
sbs waterproofing membrane is mostly used in roofs, exterior walls, and large-area waterproofing constructions. Compared with painting waterproof coatings, it is more efficient, and has good puncture resistance, high temperature resistance, and corrosion resistance. However, waterproofing membranes have higher requirements for construction. , So if you want to have a good waterproof effect, you must pave the waterproof membrane. In terms of effect, what factors affect the sbs waterproofing membrane?
High temperature can accelerate the oxidative aging of sbs waterproofing membrane. For some waterproof membranes with high boiling point, low volatility and good compatibility with asphalt felt, the toughness of asphalt felt can be improved, and too high temperature will also promote the migration of plasticizers. This leads to increased brittleness of the waterproofing membrane and easy breakage.
The manufacturer of sbs waterproofing membrane tells you that the roof structure of a building has a great influence on the roof slope and other ordinary waterproofing membranes. If the roof slope is large, the roof precipitation can make the roof drainage smoothly, reducing the contact time of rainwater and the asphalt waterproofing membrane, and reduce The probability of leakage of the waterproofing membrane, thereby prolonging the service life of the waterproofing membrane.
The manufacturer of sbs waterproofing membrane tells you that rainfall has almost no direct impact on the performance of waterproofing membranes. For ordinary waterproofing membranes with waterproofing effect, more frequent and long-term roof water will also cause local damage. The snowfall process is accompanied by a cooling and long-term melting process, which will also increase the brittleness of ordinary waterproofing membranes and easily break.
The manufacturer of sbs waterproofing membrane tells you that improper construction technology is also a factor that causes leakage or damage to roof waterproofing membranes. For example, the roof base is uneven or the base is not cleaned, so that the concrete mixes with other dust to form an isolation layer. The leveling layer has low strength and poor quality; large roof area and unreasonable joints will affect the waterproof effect.
The sun is not good for flexible waterproofing membranes. Solar energy increases the temperature of the asphalt felt and causes a chemical reaction, thereby accelerating the oxidative aging of the waterproofing membranes, reducing the toughness and brittleness of the waterproofing membranes, and being easy to break and leak water.
The waterproof effect of sbs waterproofing membrane is affected by the above aspects. I hope that the editor’s sharing can help everyone. If you have any other questions about sbs waterproofing membrane, you can leave a message to the editor in the message area below.
