The hottest Henan takes various measures to promot

Henan has taken various measures to promote the development of green building materials

in August 2016, Henan Provincial Department of housing and urban rural development and the Provincial Department of industry and information technology jointly issued the "measures for the management of evaluation marks of green building materials in Henan Province", which encourages enterprises to develop, produce, promote and apply green building materials, and stipulates that the construction projects of green buildings in the province should use green building materials with evaluation marks, and encourage new construction, reconstruction For expansion and other construction projects, priority should be given to the use of green building materials with evaluation marks

in July 2016, Henan Provincial Commission of industry and information technology and the Provincial Department of housing and urban rural development jointly issued the implementation plan of Henan Province for promoting the development and application of green building materials () (hereinafter referred to as the plan). Green building materials refer to building materials products that reduce the impact on natural consumption and ecological environment in the whole life cycle and have the characteristics of "energy conservation, emission reduction, safety, convenience and recyclability". The implementation plan defines seven key tasks, including improving the performance of cement and concrete, developing new walls and energy-saving thermal insulation materials, developing wood structure buildings and biomass building materials, developing environmental friendly high-quality chemical building materials, promoting prefabricated buildings and components, promoting energy-saving glass and energy-saving doors and windows, promoting ceramic thin bricks and water-saving sanitary ware, and proposes to carry out green manufacturing in the building materials industry, evaluation and identification of green building materials Six special actions, including the development of green building materials industry, the cultivation of key enterprises, the guidance of scientific and technological innovation, and engineering application demonstration

according to the main objectives set in the plan, by 2018, the proportion of green building materials production in Henan will be significantly increased, and the quality of development will be significantly improved. The proportion of green building materials in the main business income of the industry should be increased to more than 30%, and the main business income of green building materials should reach 300billion yuan. The development of industrial agglomeration should take shape, cultivate 23 production bases of green building materials industry with an output value of more than 10 billion yuan and 30 key enterprises with an output value of more than 1 billion yuan; Develop 57 prefabricated construction industry bases, cultivate the production, application, operation and maintenance consortium of prefabricated buildings, and basically meet the application needs of prefabricated buildings accounting for 10% of new buildings; Compared with 2015, the energy consumption per unit added value of the building materials industry decreased by 8%, and the total emission of nitrogen oxides and dust decreased by 8%; The application proportion of green building materials has increased steadily. The application proportion of green building materials in new buildings reaches 30%, the application proportion of green buildings reaches 50%, and the application proportion of pilot demonstration projects reaches 70%

the twin-screw extruder has less heat generated by friction. 2. The functional characteristics of the measurement and control software of the ring stiffness experimental machine: the shear of materials is relatively uniform, the conveying capacity of the screw is large, the extrusion volume is relatively stable, and the materials stay in the barrel for a long time. The plan clearly defines seven key tasks, such as the promotion of prefabricated buildings and components, and puts forward six special actions, such as the manufacturing, development, evaluation and identification of green building materials. The two departments will also issue the management measures and Implementation Rules for the star rating of green building materials, publish the catalogue of green building materials in Henan, guide the construction industry and consumer selection, and promote the construction of a unified, open and orderly green building materials market in the province; Establish a green building materials database and information collection and sharing system, and release green building materials evaluation marks, pilot demonstrations and other information; Build a mechanism for the selection of green building materials, dredge the channels for the selection of green building materials in construction projects, and realize the traceability of product quality. At the same time, set up a special fund for the development of green building materials, and give loan discounts to enterprises engaged in the production and application of green building materials; Incorporate the evaluation and identification information of green building materials into the credit acquisition system of government procurement, bidding, financing and credit granting; Study and formulate special financial subsidies for green building materials and preferential policies for value-added tax of production enterprises

the relevant person in charge of the Department of housing and urban rural development of Henan Province said that actively promoting the development and application of green building materials is of great significance for stimulating green consumption, guiding green development, accelerating the transformation and upgrading of the building materials industry, serving the development of new urbanization and green buildings, improving the living environment and building ecological civilization

it is understood that the green building materials referred to in the Measures refer to building materials products that can reduce the consumption of natural resources and reduce the impact on the ecological environment in the whole life cycle, and have the characteristics of "energy conservation, emission reduction, safety, convenience and recycling". Green building materials evaluation marks refer to the activities of evaluating, confirming the green grade of building materials products and carrying out informational marks according to the evaluation standards of green building materials and the procedures and requirements determined in the measures

marks include certificates and marks. The manufacturer applies for corresponding star marks from the corresponding green building materials evaluation organization according to the product characteristics and evaluation technical requirements. They are traceable and can be divided into three levels, from low to high, into one star, two star and three star. The period of validity of the logo is 3 years, and an extension of re evaluation can be applied for 3 months before the expiration of the period of validity. The ready mixed concrete production enterprise applying for the logo shall obtain the corresponding star level green production logo at the same time that its products obtain the green building materials evaluation logo through the star level evaluation

as early as 2014, it was jointly hosted by the Henan provincial government and the China Building Materials Federation, and jointly hosted by the Henan Provincial Department of industry and information technology and the Henan Provincial Department of housing and urban rural development. It aims to strengthen the interaction and complementarity between the building materials industry in Henan Province and other well-known enterprises, promote the agglomeration and development of its green building materials industry clusters, and the green building materials industry transfer docking conference, which is transforming from big to strong, A total of 39 projects were signed at the meeting, with a signed amount of 24.2 billion yuan

under the internal economic cycle, in April 2021, China Chengdu Jianbo 4. Equipment accuracy level: 0.5; I will talk with you about new opportunities in the industry

in 2020, with the outbreak of the global epidemic to the effective control of the prevention and control of the domestic epidemic, the global economic pattern has also undergone great changes, and China is pursuing [as a result, the physical and chemical properties of nano materials are different from the atomic and molecular details of microstructure]
