    2011 is the first year of single-storey roof development, in this year, single-story roofing standards, test methods are basically complete, for the later to vigorously promote the development of single-storey roofing provides a basis. Subsequently, "single-layer waterproof coil roof engineering technical regulations" and other standards have been issued, and under the leadership of the China Building Waterproof Association, carried out single-storey roof construction skills training, single-story roofing has achieved rapid development.
    With the further development of industrialization, the market demand for single-storey roofs has increased year by year, and since 2013, single-storey roofs have actually entered a fast track of development, with an annual growth rate of more than 50%. Rapid development has attracted more enterprises into the single-storey roofing field, bringing greater market competition, but also exposed more deep-seated problems.
    Since the single-story roofing technology entered China more than ten years ago, the completed single-story roofing project has slowly exposed various degrees of quality accidents over time, and the problems of single-layer waterproof coils in material quality and construction technology have attracted the attention of the society.
    material quality of single-layer waterproof coils is mainly caused by problems in the production process, including equipment, technology, raw materials and so on.
    In terms of equipment, in 2013 the Ministry of Industry and Information Technology issued and implemented the "Building waterproof coil industry access conditions", the production capacity of polymer waterproof coil production line put forward a more clear requirements, but in the production process and corresponding technical and quality standards, did not put forward enough specific indicators. Production enterprises in the introduction of production lines, as long as the capacity can meet the access requirements, basically can enter the industry. At present, whether foreign TPO or PVC production lines, its investment funds are generally more than 10 million U.S. dollars, and domestic production line investment is basically within 3 million yuan. Different prices of production lines, the main difference is the quality of production equipment, so there is a great gap between foreign production lines and domestic production lines of the production process, which is also the cause of domestic single-storey roof waterproof coil quality problems an important reason. We still have a lot of room for improvement in the production equipment of waterproof coils on single-storey roofs.
    In the process, most of the production of polymer waterproof coils of enterprises are from the production of asphalt-based waterproof coils, most of these enterprises lack of plastic processing experts, lack of production of TPO, PVC and other waterproof coils to provide more technical guidance think tank. At present, the domestic polymer waterproof coil production line extruder power is relatively small, but also relatively short, these small equipment is difficult to complete a one-time mixing, melting, plasticization, shearing and other processes, which resulted in the production of polymer waterproof coil in the performance of a certain degree of instability.
    in the single-layer waterproof coil construction technology, the domestic general lack of professional construction team. In order to ensure the quality of building waterproofing, waterproof coils are highly dependent on construction technology, and the dependence of single-story roofing system on construction technology is particularly high, requiring technical support in all aspects such as system design, construction tools, skilled workers, post-management, etc. In 2010, The China Building Waterproofing Association led the establishment of the country's first roofing system anti-wind unveiling laboratory, since 2013, the China Building Waterproofing Association has invited foreign roofing experts to China every year for training, the most advanced single-storey roofing design concepts, construction tools, construction technology to the domestic, the establishment of a domestic single-storey roofing trainer system, the establishment of professional training institutions, improve the domestic level of single-storey roofing construction skills. At the same time, through the single-storey roofing technology seminar and other forms, to introduce the latest construction cases to the industry, the construction experience of large enterprises in the seminar to share.
    On July 15, 2016, China Building Waterproofing Association will hold the "2016 Single-Storey Roofing Technology Seminar" at the Shanghai Expo Exhibition Hall, where Klaus Maffei of Germany and Amte of Italy will share the latest polymer waterproof coil production equipment technology, Beijing Oriental Rain Rainbow Waterproofing Technology Co., Ltd., Germany's Vida Corporation and Shandong Sida Construction Systems Co., Ltd. will share single-story roofing construction cases, such as modified asphalt waterproofing machinery fixed double-layer construction.
    hopes that through opportunities such as the "2016 Single-Storey Roofing Technology Seminar", the single-story roofing industry can see more advanced production equipment technology and construction technology, thereby improving the quality and construction level of single-story roofing waterproof coils and reducing the leakage rate of single-story roofing projects.
