China Drying Network News On October 18th, the state-level “New Fertilizer Experiment Demonstration and Promotion Baseâ€, which is expected by agrochemical companies, was launched in Xuzhou. China Petroleum and Chemical Industry Federation Agrochemical Service Office, China Chemical News, Beijing Sinochem United Certification Co., Ltd., and CNPC Northwest Sales Co., Ltd., and the heads of Win-Win Group Co., Ltd. signed an agreement on a new type of fertilizer experiment demonstration base. More than 200 representatives attending the "3rd National Agrochemical Service Work and 2012 New Fertilizer Strategy Development (Batian) Seminar" witnessed the launch of the event.
The “New Type Fertilizer Experiment Demonstration and Promotion Base†is initiated by the Federation, approved by the State-owned Assets Supervision and Administration Commission, and approved by the National Development and Reform Commission, “Low Carbon Chemical Innovation Technology and Product Application and Promotion Service Platform Construction Projectâ€. The project aims to scientifically verify and standardize the promotion of new products and technologies that have emerged in the field of fertilizer production in recent years. Through dissemination of the concept of popularizing scientific fertilization, the effect of new fertilizers has been tracked and scientifically validated and evaluated objectively. At the signing ceremony, Feng Weili, deputy editor-in-chief of China National Petroleum and Chemical Network TV, said that the demonstration and promotion of new fertilizer trials will be promoted one by one according to the appraisal management assessment method, with the “Agricultural Resources Dailyâ€, China Petroleum and Chemical Network TV, and the fertilizer exhibition online as The official promotion platform will highlight the functions of video shooting production and network broadcasting. Through the introduction, agrochemical expert guidance, and farmer's on-site use and display, it will exhibit the features of new fertilizers and their supporting use technologies. The demonstration promotion will also be held to promote the outstanding base awarding and recognition activities in the year.
Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.
