Zibo AoHong Chemical Technology Co., Ltd. was founded in March 2011 .Registered capital of 10,800,000 yuan. Is a professional fluorine chemical Series of products and related chemical products production, development and sales of high-tech enterprises.
At present, the first phase of the project, "an annual output of 10,000 tons of difluoromethane" project has been completed and put into production Why this a fluorine-containing refrigerant HFC-32 as traditional refrigerant alternatives to its. Its chemical properties are stable, non-toxic, suitable for the critical point and boiling point, As well as the relatively low freezing point, In the traditional Freon substitute products in excellent performance More because of its low viscosity, high thermal conductivity and energy efficient performance IT"s widely used in R410a, R407c and other mixed refrigerant, At the same time, R32 can also be used as a refrigerant alone, Market prospects are better, faster development, is a new type of highly efficient green refrigerant.
Phase II Project - An annual output of 10,000 tons of pentafluoropropane project. As an important kind of HFCs, pentafluoropropane (HFC-245fa) has the properties of not destroying the ozone layer, Low greenhouse effect, less damaging to the environment. According to the authoritative department's prediction. The total demand for HFC-245fa is increasing year by year. By 2016, the total amount of demand is increased by about 50 thousand tons, and the total demand in 2017 is expected to reach 150 thousand tons.
