On December 7th, 2011, the research and development of the new science and technology major project of Fujian Province, which was completed by the researcher of the Fujian Institute of Physical Education, Lu Canzhong , was organized by the Provincial Science and Technology Department.
It is reported that this topic has carried out innovative research work on new lithium battery materials and their products, and has carried out research on synthesis methods and processes of new lithium battery electrolyte additives such as propylene sulfate, breaking through fractionation reaction, catalytic transesterification and rectification. And key technologies such as recrystallization, developed large-scale production process and process control technology, developed two kinds of flame retardant additives such as allyl phosphate and N,N-diallyl-diethoxyphosphoramide. 20 tons/year of propylene sulfate, divinyl carbonate, tris(trimethylsilyl)borate, tris(trimethylsilyl)phosphate, ethylene sulfite, 5 electrolytes Film-forming additive production line; two lithium iron phosphate demonstration production lines of 30 tons/year and 100 tons/year were built by two kinds of process routes; batch kilogram titanium was prepared by mixing, dispersing ball milling, calcination and calcination. Lithium acid sample; two lithium ion battery demonstration production lines of 40Ah (80,000/month) and 50Ah (60,000/month) were built by two kinds of process routes.
It is understood that the topic was completed by the Fujian Institute of Physical Education, Xiamen University, Fujian Chuangxin Technology Development Co., Ltd., Youke Energy (Zhangzhou) Co., Ltd., Xiamen Baolong Industrial Co., Ltd. and Xiamen Tungsten Industry Co., Ltd. It is the result of close cooperation between industry, academia and research.
In addition, during the implementation of the project, a total of 23 Chinese invention patents were granted, and 2 Chinese invention patents were authorized. The results of the “Development and Industrialization of New High-Efficiency Lithium-Ion Battery Electrolyte Additives†won the 2010 Third Prize of Science and Technology Progress of Fujian Province. prize.
The apron sink front protrudes slightly from the supporting cabinets, eliminating countertops that cause users to lean forward and over-stress. At the same time, this practical design helps prevent cabinet damage. The apron sink is easy to install following this video. Made of high quality stainless steel, this handmade sink is not only anti-corrosion and anti-scratch,but also strong and durable.Its Modern and stylish appearance fits into any style of kitchen.
