Information
Strictly speaking, only SBS modified asphalt waterproof membranes that require hot melt construction are banned, not all SBS waterproof membranes. Moreover, according to authoritative research and analysis reports, the disadvantages of "unsafe and environmentally friendly" SBS waterproof coiled materials are relative.
SBS waterproof membrane is a kind of waterproof material commonly used in early waterproof engineering. These SBS waterproof membranes are mostly hot-melt constructions, which require open flames and are often labeled as "unsafe and environmentally friendly". Nowadays, the state advocates green development, and some cities have rectified the infrastructure and building materials market in order to guide production and construction enterprises towards green building materials. It is required to prohibit the use of "hot-melt construction SBS" in new construction, reconstruction, expansion, and maintenance projects. "Modified bituminous waterproof membranes, solvent-based architectural waterproof coatings", and stated that it can be replaced by non-open flame construction waterproof membranes such as polymer self-adhesive film waterproof membranes and PVC membranes.
In fact, domestic well-known waterproof manufacturers such as "Yuwang", "Yuexing Brand", "Yuhong" and other manufacturers use SBS waterproof membranes made of domestic high-quality petroleum asphalt. The main emission substance after combustion is CO2, which is harmful The gas is negligible, and the hot melt construction of SBS asphalt coils is not burning asphalt, but merely indicating that the coils are melted. The softening point of asphalt is about 90℃, and the ignition point is above 280℃. Strictly speaking, correct construction Under the circumstances, hot melt construction will not affect the environment. However, since the development of waterproof membranes, non-standard membranes are rampant. Raw materials are mostly made of reclaimed rubber and waste rubber powder. The hot melt will have a great impact on the environment, and the construction workers are likely to cause various kinds of problems due to lack of professional construction skills. Potential safety hazards are the biggest culprits that cause misunderstandings of hot-melt waterproofing membranes.
