the national standard" technical specification for rigid polyurethane insulation and waterproofing engineering "edited by Yantai assimilation waterproof and insulation engineering Co., Ltd., which has been revised for two years and six times, It passed the review of the expert group a few days ago and will be officially promulgated and implemented in August. It is the first time for private enterprises to take the lead in editing the national standards for engineering construction in the province

the national standard "technical specification for rigid polyurethane insulation and waterproof Engineering" is the preparation plan of engineering construction projects issued by the Ministry of construction in 1999, which was once stranded for various reasons. In 2004, Yantai assimilation waterproof and thermal insulation engineering company, as the "leading goose" in the National Waterproof and thermal insulation industry, was designated as the editor in chief of the specification by the standard quota Department of the Ministry of construction. It was nominated by the company and agreed by the standard quota Department of the Ministry of construction. 12 colleges and universities, such as China Academy of Building Sciences, China building waterproof materials industry association, and China Metallurgical Corporation Building Research Institute, such as the Institute of large deformation under impact load Associations and enterprises are participating units

this specification summarizes the practical experience of developing rigid polyurethane in the design and construction of building insulation and waterproof engineering in China in recent 10 years. The participating units are backbone enterprises engaged in rigid polyurethane materials and applications for 5-10 years. As a comprehensive waterproof and thermal insulation company with secondary waterproof and thermal insulation construction qualification, Yantai assimilation waterproof and thermal insulation engineering Co., Ltd. integrates scientific research, production, design and construction. It is committed to developing and developing a new building composite material - th rigid foam polyurethane composite board external wall waterproof and thermal insulation system, which is mainly introduced in the following The waterproof primary construction technology has filled the domestic gap. It has been listed as the promotion project of scientific and technological achievements of the Ministry of construction, and the serious oil leakage of the national oil pipeline system. It is important to check whether the oil pipeline is the product selected for the broken comfortable housing demonstration project. It has been used in national key projects such as the Great Hall of the people, the banquet hall of the Great Hall of the people, the ministerial residential building of the State Council organ affairs administration, and national grain reserves all over the country
