Add a touch of green to the thermal insulation project
Zhejiang Building Materials Quality Association two group standards start meeting heldThe "Standard Adhesive for Foam Glass Low Temperature Insulation Engineering" and the "Mastic" for Foam Glass Low Temperature Insulation Engineering organized by Zhejiang Building Materials Standardization Technical Committee and Zhejiang Building Materials Quality Association. On March 29th, it was held in the conference room of Zhejiang Dehe Thermal Energy Technology Co., Ltd., 6th Floor, Xiuzhou Chamber of Commerce Building, Xiuzhou District, Jiaxing City. The meeting confirmed the establishment and division of the two standards preparation working groups, and formulated the work plan for the preparation of two group standards. The editorial unit of the Jiaxing City Fangyuan Fair Inspection Institute elaborated the discussion draft of the above two standards, and the representatives of the participating units discussed the discussion. The draft was discussed and negotiated.
Yang Xiwei, China Building Energy Conservation Association: It is imperative to change the status of external wall insulationAbstract: On July 26th, 2017, “10 years of thick accumulation of green building ingenuity”, the achievements of the company’s ten-year achievements in the production of the 100-year-old building tasting was held in the grand opening of the Jiaxing Shizun Hotel in Changsha, Hunan. Developers and experts in the insulation industry gathered to share the achievements of the company's finished products for ten years and to explore new technologies in the field of insulation. At the meeting, Yang Xiwei, deputy secretary-general of the China Building Energy Conservation Association and deputy chief engineer of the former Ministry of Housing and Urban-Rural Development, delivered an opening speech.
Fireproof grade and application of foam glassUsually building materials generally have 5 fire ratings: Class A: Non-combustible building materials: Materials that hardly burn. Class A1: Non-combustible, no open flame A2 class: Non-combustible, to measure smoke, to be qualified. Grade B1: Flame retardant building materials: Flame retardant materials have good flame retardant effects. It is difficult to catch fire when exposed to fire in the air or under high temperature, and it is not easy to spread quickly. When the fire source is removed, the combustion stops immediately. Class B2: Combustible building materials: Combustible materials have a certain flame retardant effect. In the air, when exposed to fire or under high temperature, it will immediately ignite and burn, which may lead to the spread of fire, such as wooden columns, wooden trusses, wooden beams, wooden stairs, etc. Grade B3: Flammable building materials: no flame retardant effect, extremely flammable, and dangerous to fire. The national standard must reach the level of GB 8627 B1.
Thermal insulation wall material market has broad prospectsAccording to statistics, China's building energy consumption accounts for 23.1% of the total energy consumption, while the annual heating of various buildings and cooling energy consumption accounts for about 10% of the total energy consumption in the country. It is necessary to develop and produce energy-efficient building insulation materials such as foam glass. It can turn waste into treasure, reduce pollution and promote environmental protection. It is rich in raw materials, simple in production technology and equipment, low in investment, low in cost, convenient in construction, and integrates heat preservation and environmental protection. It is a new type of thermal insulation energy-saving material with great development prospects. It is suitable for glass factories and various building materials enterprises for production. In the "National Economic and Social Development" Eleventh Five-Year Plan and the Vision 2020, China has listed the construction industry and building materials industry as the pillar industries of the country. During the 11th Five-Year Plan period, the completed area of urban residential buildings in China, together with other public buildings, will reach a total construction area of more than 5 billion square meters. Such large-scale housing construction, wall materials account for about 70% of building materials. The amount of demand can be imagined. In 2010, the state demanded that the output of new wall materials accounted for 40% of the total wall demand. If it is still calculated according to the total construction completion area of 5 billion square meters during the fifteenth period, it will reach 2 billion square meters. If 1% applies foam glass, It will require 1 million cubic meters of foam glass. As a new low-cost green energy-saving and environmentally friendly product, foam glass will play an important role in the revolution of new wall materials in China. The project was reported in April 2010 in the “Close to Science” section of the Central Committee. At the end of 2010, the Ministry of Construction of China decided to achieve the goal of achieving a building energy efficiency rate of 50%. This means that the building energy-saving materials market will require a large number of products with excellent mechanical properties, remarkable energy-saving effects and low prices in the next few years. The primary task of building energy conservation is to save energy in the wall. Therefore, improving the thermal insulation performance of the building wall is the key to reducing the energy consumption of the building. At present, China is actively developing and producing wall insulation materials, which can improve the thermal resistance of the wall and reduce the heat transfer coefficient of the wall. Insulation wall materials should have a good development prospect in the future market. According to statistics, before the end of 2010, China's urban residential, public and productive buildings required about 2.87 billion square meters of thermal insulation materials, and the potential market for insulating wall materials was large. China's priority building materials during the 11th Five-Year Plan include: new wall materials and new insulation materials. At present, foam glass has been listed in the new building materials catalogue that is promoted and developed by the state. Foam glass building insulation materials have been incorporated into the architectural roof and exterior wall insulation standard atlas, laying the foundation for the application of foam glass in the field of building insulation and energy conservation.
