This event is hosted by the Insulation and Energy Saving Committee of the China Building Materials Circulation Association and the Hunan Construction Technology and Building Energy Saving Association, and undertaken by the Changsha Waterproof, Anticorrosion and Thermal Insulation Industry Association, and co-organized by Hunan Guangfu Technology Co., Ltd., Changsha Pinpai Paint Co., Ltd., Hunan Dayu Waterproof Building Materials Technology Co., Ltd., and Hunan Zhuoyi High-tech Co., Ltd.
With the rapid development of the economy and the improvement of people's living standards, people are paying more and more attention to the living environment. Green, low-carbon and environmentally friendly building materials have gradually become the direction of development of the construction industry. Building wall insulation is an important support for building energy conservation. However, in real life, problems such as wall cracking, hollowing, water seepage, falling off and fire have challenged the quality of external insulation projects. "The improvement of the quality of external insulation projects must be controlled from the aspects of procedures, technology and management." Promote the application of new technologies, reduce process links, prepare thermal insulation integrated panels in the factory, pre-combine the insulation layer and the finishing layer, and strengthen the supervision and management of the construction process. Cheng Jie, a researcher at the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development, analyzed the quality of external insulation projects in the industry in recent years and proposed quality improvement strategies from multiple dimensions, stages and aspects.
"The fireproof grade of the heat-setting board reaches the A-level fireproof standard, with low thermal conductivity, good thermal insulation effect, light weight, easy construction, good toughness and high strength..." Hunan Guangfu Technology Co., Ltd. is a manufacturer of heat-setting composite polystyrene fireproof insulation boards in Hunan. At the scene, Yu Liqiang, vice president of the Hunan Construction Technology and Building Energy Conservation Association and technical director of Hunan Guangfu Technology Co., Ltd., introduced a new material commonly used for insulation - the heat-setting board, and fully demonstrated the heat-setting board to everyone from the performance comparison of commonly used insulation materials, product advantages, and practical applications in the market.
As a local professional waterproofing company in Hunan, Hunan Dayu Waterproof Building Materials Technology Co., Ltd. produces a series of waterproofing product categories for different scenarios, and is applied to various places in life: basement floors, garage roofs, roofs, building exterior walls... leaving no place for water to leak. Lei Chunhui, general manager of Changsha Dayu Waterproof Construction Engineering Co., Ltd., introduced that his company's non-leakage waterproofing system is both rigid and flexible, which not only strengthens the waterproofing design but also standardizes the waterproofing construction to achieve a stable waterproofing effect.
Regarding the topic of building waterproofing, Shen Chunlin, executive director of China Building Materials Suzhou Waterproof Research Institute and director of the Waterproof Materials Committee of the Chinese Silicate Society, took the topic of "The impact and trend of general specifications on waterproof materials" and explained in detail the key contents of the "General Specifications for Waterproofing of Buildings and Municipal Engineering" to the scene, so that everyone can understand that the quality of waterproofing projects is closely related to waterproofing materials, waterproofing design, waterproofing construction and maintenance management, among which waterproofing materials and construction quality are the key.
"Old house renovation is a good opportunity for construction practitioners!" At the beginning of the speech, Tan Rehua, vice president of Changsha Waterproof, Anticorrosion and Insulation Industry Association and general manager of Changsha Pinpai Paint Co., Ltd., went straight to the topic. The market for exterior wall renovation is huge, especially the renovation and renovation of old houses. Different exterior wall decoration materials correspond to different renovation processes. For 18 years, Changsha Pinpai Paint Co., Ltd. has focused on water-based architectural coatings for interior and exterior walls and has rich experience. Tan Rehua shared the construction technology of real stone paint for the transformation of old ceramic tile exterior walls, the water-in-water construction technology for the transformation of exterior wall latex paint, and the water-in-sand technology for the transformation of sand surface exterior wall communities, full of dry goods!
The exterior walls of early Chinese houses experienced adobe walls to cement walls. The emergence of latex paint gave the houses rich colors. Later, mosaics, tiles, real stone paint, glass curtain walls, etc. joined the ranks of exterior wall decoration. With the test of time, the survival of the fittest, imitation stone paint has become the current mainstream of exterior wall decoration. However, due to the market involution, low-priced and low-quality products flooded the market, manufacturers' profits shrank, and cruel market competition, whether to maintain price or quantity has become the number one problem. How to break the volume? Huang Yangjun, a senior media person in the coatings industry, director of the Guangdong Media Center of "China Coatings", and editor-in-chief of "New Vision of Coatings", shared that only by doing a good job in product quality and service quality and putting more effort in brand promotion can we have a chance to be invincible.
Improving product quality and service quality is the top priority for enterprise development. At the same time, enterprise cooperation is also a long-term way to sustainable development. Only by leveraging their respective advantages and working together to solve difficulties can we achieve a win-win situation. This building waterproof and thermal insulation coating exchange meeting is an industry "grand alliance" with resource sharing, unique insights, and collision of ideas. This linkage will surely bear fruit in the low-carbon and energy-saving construction industry.
