The first-phase project of annual production of 100,000 tons of inorganic phase change energy storage materials of Zhongrui Sen (Tianjin) New Energy Technology Company located in Tianjin Energy Saving and Environmental Protection Industrial Zone was put into operation. This marked a breakthrough in China's R&D and production of inorganic phase change energy storage materials. . The project covers an area of ​​200 acres and a total investment of 350 million yuan. The nano inorganic phase change energy storage material researched and developed by Zhong Rui Sen (Tianjin) New Energy Technology Co., Ltd. has been inspected and certified by the Institute of Special Materials Quality Supervision and Inspection Center of the Ministry of Industry and Information Technology. The temperature control range is -50°C~1800°C, and the number of phase transitions exceeds 10,000. Times, the service life of more than 20 years, performance parameters and technical indicators have exceeded internationally similar materials, one at a time to break the monopoly of foreign technology. The inorganic phase change energy storage technology realizes passive cooling or heating through physical changes of the phase change material so as to achieve a long-time constant temperature effect of the local environment. Zhongruisen (Tianjin) New Energy Technology Co., Ltd. cooperated with Tsinghua University and other organizations to develop a phase change constant temperature storage battery cabinet with an inorganic phase change material that can remember the temperature and automatically absorb heat and signal when the signal peaks. When the heat is released, the air conditioner has a constant temperature effect. The results of the pilot test show that the energy saving can reach more than 40%. In the past, the three major telecom operators in China have put this product into practical use and verified that the product has a constant temperature of 14 hours under high-temperature and power-off conditions, which has greatly solved the problems that plagued telecom companies due to internal temperature increase. Short life, high communication station energy consumption. According to reports, the inorganic phase change energy storage material is non-toxic, non-hazardous, non-flammable, non-corrosive, long service life, etc., used in the textile field can be processed into thermostatic (air conditioning) clothing, bedding, shoes and hats, with warm summer Cooling efficiency; used in the field of building materials can be processed into mortar, paint and other insulation materials to improve the living environment. In addition, this material can also be expected to be widely used in petrochemical , textile, refrigeration, air conditioning, industrial waste heat recovery and utilization, power generation, steel, metallurgy, aerospace and other fields.
High strength steel tie rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650, grade 785, grade 830, grade 930, grade 1080 etc.
