Jinmingyu Construction Technology Co., Ltd. is the first provincial prefabricated construction industrial base in Linyi City, integrating research and development, production, sales and service. Mainly in the production of prefabricated concrete building, steel structure building, light new building components, among which ALC, PC products were rated as national green building materials products. This article mainly introduces ALC products related content of building technology company.

Building technology company ALC products production workshop, covers an area of about 17,000 square meters. Automatic autoclave aerated concrete plate production line is the domestic advanced intelligent production line, a total of 8 autoclave. Through technical transformation, steam guide work station of steam screw machine and auxiliary equipment products of energy saving transformation are used to complete daily steam guide work of adding block production line, realize steam cycle use, improve the utilization rate of heat energy and reduce production energy consumption. At the same time, the production electricity of the workshop comes from the photovoltaic project of Jinmingyu Building Technology Company, which reduces carbon emissions, realizes green production, and greatly increases the green attribute of ALC and other products. In 2021, ALC and PC products of construction technology company were evaluated as green building materials products by China National Testing Holding Group Co., LTD.

China Green building Materials product certification is the State Administration for Market Regulation, the Ministry of Housing and Urban-Rural Development, the Ministry of Industry and Information Technology to promote the implementation of green building materials product certification system, aimed at improving the green building materials market system, increase the supply of green building materials products, improve the quality of green building materials products, promote the transformation and upgrading of building materials industry and construction industry, jointly promote national certification activities. Green building materials ALC and PC produced by building technology companies undoubtedly occupy a dominant position. The State Administration for Market Regulation, the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology issued the Notice on Accelerating the Certification and Production and Application of Green Building Materials Products. The Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly issued the Notice on Government Procurement of Green Building Materials to Promote the Pilot Work of Building Quality Improvement. Hospitals, schools, office buildings, complexes, exhibition halls, exhibition centers, gymnasiums and affordable housing included in the pilot projects of government procurement projects will be preferentially selected as green building materials, and those who have obtained the "identity certification" of green building materials will be preferentially selected by government projects. Policy support, national attention, so that Jinming Yu building technology company more potential development.

Jinming Yu building technology company production of autoclaved aerated concrete reinforcement board (ALC board), as a national recognized green building materials products, the main raw materials using tailings sand, fly ash, slag and other waste, its products have the advantages of light, high strength, high doping insulation, environmental protection and energy saving, seismic sound insulation, beautiful and practical.

ALC board is a kind of light porous new green building material, mainly used for building exterior wall and interior partition wall. The internal structure of ALC slab determines the high quality performance of autoclaved aerated concrete reinforced slab. The pores formed in the aerated concrete plate surrounded by pore wall materials can be divided into two types: macropores and micropores. Macropore, visible to the naked eye, also called macropore. It's formed by air bubbles, so it's often called a stoma. Its size varies from about 2mm to less than 0.5mm. Micropores exist in the walls of stomata and can only be seen clearly by magnifying them with a microscope. It includes capillary pores, gel pores and intergranular pores. Intergranular pores between gel particles can also be seen under an electron microscope or a scanning electron microscope. That is, the autoclaved aerated concrete plate is filled with countless independent tiny pores, holes and holes are not through, water can not smoothly through the pores, can not run through the plate. Therefore, ALC products have unparalleled thermal insulation performance. Qualified aerated concrete plate to do the exterior wall, as long as the joint up and down good sealant, plate and plate joints do a good job of waterproof treatment, that is to prevent water leakage, seepage phenomenon.

Jinming Yu building technology company production of autoclaved aerated double reinforcement sheet, with its excellent product performance by the market. At present, the annual output of ALC can reach 300,000 cubic meters, which are exported to Handan, Nanjing, Qingdao and other places in Hebei Province.
