Chinanews.com, April 24. Recently, a seminar on the development of polyethylene polypropylene coil composite waterproofing technology was held in Beijing. The conference was organized by the Waterproofing Professional Committee of the China Engineering Construction Standardization Association and the Waterproofing Technical Committee of the Construction and Building Materials Branch of the Chinese Architectural Society. Co-sponsored by Beijing Shengjie Waterproof Material Co., Ltd., Hakoke Suileng Second Plastic Co., Ltd., Qinhuangdao Songyan Building Material Co., Ltd., Shanghai Qiaomao Building Waterproof Material Co., Ltd., Qinhuangdao Tianyi Waterproof Material Co., Ltd., etc. At this conference, industry experts called for speeding up the development of industry standardization.

On the same day, the waterproofing experts and relevant management personnel in the field of waterproofing engineering construction, the representative of the editor-in-chief of "Technical Specifications for Roofing Engineering", "Technical Specifications for Underground Engineering Waterproofing", and the editing team of "Technical Specifications for Polypropylene Polypropylene Coil Composite Waterproofing Engineering" (CESC199) Members, representatives of major manufacturers of polyethylene polypropylene coils cooperated with the revision of the Technical Specification for Polyethylene Polypropylene Coil Composite Waterproofing Engineering (CESC199), and also made people inside and outside the industry have a comprehensive, A fair, objective, and correct evaluation promotes the healthy development of polyethylene polypropylene fiber composite waterproof technology.
According to reports, "Polypropylene polypropylene coiled composite waterproofing" refers to the waterproof structure formed by the combination of polyethylene polypropylene coiled material and polymer cement, which can be used on cement, metal, plastic, glass and other substrates. In the composite waterproof structure of polyethylene polypropylene fiber coil, it is the combination of the two, which gives full play to the advantages of the two and makes them complementary. Coils cannot be used independently, so the thickness of the coil cannot be simply used as a basis for evaluating this technology.
The development of polyethylene polypropylene coil composite waterproofing is full of twists and turns. In the 27 years since the introduction of this waterproof material, the technology used to use cement paste as a primer has been changed, and it has been updated to use polymer cement waterproof coatings, non-cured rubber asphalt coatings, polyurethane waterproof coatings, acrylic waterproof coatings, and various kinds of Viscous waterproofing membranes are used for composite construction, and become flexible-flexible, flexible-flexible waterproofing methods. It is used for building roof, underground, roof, subway, water conservancy, planted roof, underground rainwater collection, subway, water conservancy and other waterproofing projects. It is a product and process that is compatible with green buildings.
In fact, this waterproof technology has been proved by a lot of engineering applications and scientific tests to prove that it is a good composite waterproof technology, not just embodied in coils. At the same time, this technology has been developed on the basis of the original technology. Expanded the scope of use and promoted the development of technology.
Due to the existence of inferior polyethylene polypropylene fiber coils on the market and their irregular use, coupled with the lack of substantial understanding of this technology by some personnel, incorrect judgments have been produced, which has affected the reputation of this technology. Gao Yanji, a senior engineer of the waterproofing professional committee of the China Engineering Construction Standardization Association, pointed out, "Some experts say that this material is not good by feeling. I used to feel it, and now I have done a lot of experiments to prove that this material is good." As an example, the waterproof project of the Sihuidong subway platform originally used SBS modified asphalt coils. After a leakage accident, the polyethylene polypropylene fiber coil composite waterproof technology was used.
Gao Yanji revealed that the key considerations in the revision of the regulations include three aspects: the requirements for polyethylene polypropylene coils are given from physical and mechanical indicators to distinguish raw materials from recycled materials, and the appearance of polyethylene polypropylene coils To judge the use of inferior coils; to put forward the unified requirements for polymer cement cement materials, which cannot meet the requirements, and to use foreign technologies, we must combine our use summary to get reasonable and effective use. In addition, the related equipment, tools, tools, supporting parts and other application technologies are improved.
At the meeting, representatives from companies such as Qinhuangdao Songyan, Ha Gaoke Suileng Second Plastic, Shanghai Qiaomao and Beijing Shengjie also gave separate reports on "polypropylene production, construction technology and application".
It is reported that Beijing Shengjie Waterproof Material Co., Ltd. was established in 1999 with a registered capital of 70 million. Committed to the systematic exploration and research of waterproofing problems, after more than ten years of accumulation and precipitation, Holy Waterproofing has developed into a comprehensive waterproofing company that integrates product development, production, sales, and construction. It is the top 20 waterproofing companies in China. With national professional waterproof qualification.
