The national stard of rigid foam polyurethane insulation waterproof engineering technical regulations was affirmed
Refrigeration Express News: In order to promote the development of wall insulation technology in my country, promote excellent insulation materials and related scientific and technological achievements in building energy-saving projects, and further improve the national standard "Technical Regulations for Rigid Foam Polyurethane Insulation and Waterproof Engineering", "Technical Standards for External Wall Insulation and "Market Application Symposium" was held in Yantai recently.
Representatives from the Science and Technology Development Promotion Center of the Ministry of Housing and Urban-Rural Development and Yantai Housing and Urban-rural Development Bureau, Vanke Group, Shanghai Sanxiang, Beijing BBMG, China Railway Real Estate Group and other enterprises attended the meeting. Yantai Tonghua Waterproof and Thermal Insulation Engineering Co., Ltd., as a backbone enterprise in my country's rigid foam polyurethane production and R&D, was commissioned by the Ministry of Housing and Urban-Rural Development to undertake the editor-in-chief of the national standard "Technical Regulations for rigid foam polyurethane thermal insulation and waterproof engineering" (GB50404). At the meeting, assimilation The company gave a comprehensive introduction to the background, work and main content of this standard revision. This meeting was held with the assistance of the National Building Energy Conservation and Construction Technology Promotion Service Platform.
During the period, the leaders and experts at the meeting fully affirmed the standard compilation work of Assimilation Company, and believed that the revision work was carried out very timely. The revised "Regulations" combined with the current development of China's foreign wall insulation technology, and is a verification test and Developed on the basis of extensive engineering practice, the content of the revision is detailed and accurate. The "Regulations" are conducive to further standardizing the rigid foam polyurethane industry standards, effectively improving and perfecting the technical implementation level of rigid foam polyurethane building exterior insulation projects, and will further advance The healthy development of China's rigid foam polyurethane building external insulation project.
According to experts in the large air-conditioning and refrigeration market, building energy conservation is my country's basic national policy. In recent years, as the country has continuously improved building energy conservation standards, the performance requirements for thermal insulation materials have become higher and higher. Rigid foam polyurethane has many advantages such as low thermal conductivity and good fire resistance, and is more and more widely used in various building insulation projects.
