Oxyfuel glass kiln process and industrialization technology mainly uses high-purity oxygen to replace air and fuel for combustion, and heats the uniformly mixed powder to high temperature melting, then through the process of homogenization, clarification, cooling and temperature regulation of glass liquor to form a glass liquor with uniform composition, less defects and meeting the requirements of forming temperature. This technology significantly reduces flue gas and dust emissions and exhaust heat loss. At the same time, the fuel combustion is more complete, the flame radiation glass liquid temperature is increased by about 100℃, and the melting rate is increased by 20%, thus achieving energy saving and carbon reduction.

High-performance geogrid manufacturing and application technology takes polymer, inorganic fiber and other raw Material as raw Material, and the grid-like products made by raw material modification, fiber composite warp knitting and other technologies, which have high tensile strength, corrosion resistance, high construction efficiency and low price, and can be used instead of steel bars in road facility construction projects. At the same time, waste plastic and recycled fiber can be used as raw Material, and all the resulting edge waste is recycled to achieve 100% utilization of raw Material.

Ceramic raw material dry powder technology adopts the "pre-crusher, vertical mill" "dry → dry" operation process, reducing the granulation spray tower link, directly saving more than 70% of water, reducing the evaporation of this water with electricity and fuel generated by carbon dioxide and pollutant emissions. emissions.

Based on alkaline earth metal compound salt adiabatic (thermal insulation) coating technology uses alkaline earth metal compound salt material as filler added to the coating, so that the product has the characteristics of large far-infrared radiation rate, can be in a specific ambient temperature -60 ℃ ~ 70 ℃ interval, the energy of the main radiation band 8 ~ 14 μm for radiation heat exchange, can significantly reduce the heat flow density of the building wall, reduce heat transfer, so as to achieve Thermal insulation effect.

The ecological pre-treatment of domestic waste and cement kiln co-disposal technology combine the ecological pre-treatment outside the kiln and the harmless and resourceful post-disposal inside the kiln to treat and dispose of domestic waste. First, the waste is pretreated by microbial fermentation and physical drying, mechanical sorting and other technologies to obtain cement kiln waste pretreatment combustible Material, inorganic ash, metals, leachate, etc. Then, the firing system of the new dry process cement kiln is used for multi-point co-disposal of waste pretreatment combustible Material (CMSW) to achieve the effect of replacing part of the fuel (coal), while the inorganic components can be made into cement raw Material The inorganic fraction can be fed into the new dry process cement kiln system to replace some of the raw Material. This technology can achieve the effect of energy saving and carbon reduction by using the combustible components of domestic waste to replace traditional fuels. (According to the requirements of the Technical Policy on the Prevention and Control of Solid Waste Pollution by Cement Kiln Co-disposal, it is applicable to cement kilns with a single line design clinker production scale of 3,000 tons/day and above)

20m~60m span steel pipe concrete truss bridge technology is a construction technology that uses steel pipe concrete material for the design, manufacture and installation of medium span bridges. This technology utilizes the restraining effect of steel pipe on concrete in steel pipe concrete and the combined effect of steel and concrete Material to solve the problems of low strength, poor ductility, insufficient safety reserve and high material consumption of traditional medium span bridges; it not only reduces the whole life cycle cost of bridges, but also saves reinforced concrete for traditional bridge construction, with significant economic and social benefits.

New carbon-free clay wet sand casting technology of the sand from the original sand, clay mixture made of non-toxic, odorless inorganic Material, does not contain coal dust and other organic Material, in the high-temperature iron pouring process will not burn and produce gas and dust, the sand can be reused after the high-temperature effect, reuse more stable performance, and will not cause pollution of the sand. At the same time, using the interface of metal casting/carbon free clay sand casting, the surface of the casting will not stick to the sand after solidification, which effectively improves the yield of the casting. Compared with traditional casting technology, this technology has good energy saving and carbon reduction and environmental benefits. (Applicable to the casting of mechanical equipment parts in various industries)

Winding permanent magnet coupled governor technology refers to the dynamic motor connected to the winding permanent magnet governor device to drive the permanent magnet rotor to rotate and generate the induced magnetic field. The speed regulation function is achieved by controlling the current of the winding rotor to adjust the transmission torque to suit the speed requirement. At the same time, the differential power is recycled to solve the problem of temperature rise generated by the differential loss, more power saving, and its performance is better than the traditional frequency converter. (Applicable to various industries such as fans, compressors, pumps and other power source power saving or control, etc.)

High-efficiency P-type PERC monocrystalline solar cell and module manufacturing and application technology reduces the amount of carrier compound on the back surface of the cell by depositing Al2O3 passivation layer on the back side of the cell to enhance the long-wave response of the cell, thus improving the cell photoelectric conversion efficiency.
