Tianjin Huanou Semiconductor Materials Co., Ltd. independently researched and developed the “method for the preparation of large-diameter fused silicon single crystalsâ€. Recently, it has obtained national invention patents and has rapidly realized industrial production, which has effectively promoted the overall upgrade of the Tianjin semiconductor industrial chain and the new energy industrial chain.
Tianjin Huanou Company has continuously conducted scientific research through the introduction of advanced equipment, and has produced a 5-inch, 6-inch-diameter zone of molten silicon single crystal, which has become a pioneer in China. Subsequently, after many experimental creations, it broke through technical difficulties such as equipment control software and operating procedures, and successfully produced the first 8-inch-diameter fused-silicon single crystal in the country, which was one of the top three in the world.
It is understood that the area of ​​its production of silicon single crystal has been widely used in high power, high voltage, high current semiconductor power electronic devices and new energy fields, and for China's aerospace solar cells provide domestic raw materials support, the product of the domestic market The share has reached more than 60%.

PET Woven Geotextile is high strength woven geotextiles manufactured by weaving high tenacity polyester filament yarns into a dimensionally stable network. The inherent characteristics of polyester – high tensile strength and modulus, low elongation, low creep and high long-term design strength - makes these products ideal for soil reinforcement applications. The fabric develops excellent frictional interaction with a wide variety of soils and granular materials.
The relatively small openings of these fabrics enable them to act as efficient separators preventing the mixing of costly granular materials with fine-grained soils. The geotextile has reasonably high permeability to prevent excessive build-up of pore-pressures due to applied loadings.
