Polymer waterproof membrane will become the main battlefield of industrial upgrading

Update:11 Apr 2020

"In the blueprint for the development of the waterproof industry in the new era, more durable and environmentally friendly polymer waterproof membranes have attracted widespread attention. Polymer waterproof membranes such as TPO, PVC, EPDM, HDPE, etc. are used in large-span roofs, important public buildings, tunnels and underground Engineering, urban underground pipe corridors and other fields have been increasingly used and become an important force to lead the technological progress of the industry and achieve industrial upgrading." Chao Wen, the president of Suzhou Waterproof Research Institute of China National Building Materials Research Institute, held the third The polymer waterproof membrane industry development seminar was announced to the outside world.

The 3rd Polymer Waterproofing Coil Industry Development Seminar was jointly organized by "China Building Waterproofing" magazine, Suzhou Institute of Waterproofing, China Academy of Building Materials Science Research, and Qingdao University of Science and Technology.

At the seminar, China Railway Research Institute, China Academy of Construction Science and Technology, Beijing Urban Construction Design and Development Group Co., Ltd., Qingdao Municipal Design Institute, Qingdao University of Science and Technology, Qingdao Metro Group, Soprema, Sika Perna, Xinda Luxin, etc. Experts, scholars, and related technical personnel from scientific research institutions, universities, construction units, design units, and material production units conducted in-depth discussions around the key factors affecting the quality of polymer waterproofing membrane products and engineering.

The future of polymer waterproof materials is huge

Qingdao University of Science and Technology is the earliest university to conduct polymer research in China. According to Qiu Guixue, a professor at Qingdao University of Science and Technology, polymer waterproof materials have high strength, good flexibility at low temperature, large elongation, and strong adaptability, which solves the problem that traditional waterproof materials are prone to cracking, thus ensuring waterproof quality; polymer waterproof materials Corrosion resistance, aging resistance and long service life, the general synthetic polymer waterproof membrane has a durability of more than 10 years.

According to Qiu Guixue, the polymer waterproof membrane can be made into various colors by adding pigments during production, and it can also play a decorative role while being waterproof.

In addition, the production process of polymer waterproof materials has less pollution, can achieve green manufacturing, can be cold construction, in line with national environmental protection guidelines.

There are many people who share the same views as Qiu Guixue. During the meeting, some representatives told reporters that the state is now strict with environmental protection. Some asphalt waterproofing companies have been reported by local residents due to non-compliance. Some have stopped production for rectification and installed environmental protection equipment; some have been punished by government departments. Had to close the door. The polymer waterproof membrane is a waterproof product encouraged by the Ministry of Industry and Information Technology. The production of polymer waterproof materials is relatively green and environmentally friendly. In the future, polymer waterproof membranes with good weather resistance and environmental friendliness will inevitably have more room for development.

"The waterproof concept and construction technology of pre-paved polymer waterproof coiled material are conducive to its application in subway waterproofing." Hu Yonghong, a professor-level senior engineer of Beijing Urban Construction Design and Development Group Co., Ltd., said that the use of polymers in open-cut construction The waterproof material, the concept of pre-laying and anti-sticking is matched with the construction method. It can be constructed on a wet base. The environmental protection, durability, and climate adaptability of polymer waterproof membranes are conducive to subway construction. In the mining method construction, compared with the traditional waterproof board, many polymer waterproof materials are welded, which is helpful to reduce the water channeling.
