WHB coal-polymer grade ethylene glycol standards

March 7 , the reporter learned from the China Nitrogen Fertilizer Industry Association , the Chinese rings Engineering Co. , Hua Shuo Technology Co., Ltd. ( former Hubei Research Institute of Chemistry ) and Hebi BMW Industries Limited jointly developed polymer-grade coal- WHB glycol new technology has made new progress . With the technology to produce ethylene glycol product has completed polymerization, spinning and dyeing and other application tests , such as ethylene glycol as raw materials to produce polyester chips and spinning and finishing performance has fully achieved , even better than some indicators petroleum ethylene glycol as a comparative sample of raw materials.Sellotape

Prior to industry experts on coal glycol project also has many fears and doubts , one of its focal point is the product can meet the aggregation level , and the ability for the production of polyester. China rings, Huashuo China Institute of Textile Technology and its southern branch cooperation , the WHB new technology to produce ethylene glycol ethylene glycol products and petroleum products at the same polymerization , spinning and dyeing comparison test, polyester chips textile fiber products through quality supervision and testing center to the glycol as raw material properties , including intrinsic viscosity polyester chips , color, carboxyl content , moisture, ash and other indicators have reached the national standard fiber grade polyester chips superior product indicators ; while the polyester dyeing after spinning its K / S values ​​, dye uptake , rubbing fastness and washing fastness and other indicators reach oil as raw material ethylene glycol comparison sample level, especially K / S value and the rate is still better than the contrast dye samples . The results show that the use of new technology to produce ethylene WHB fully available for the production of polyester .Washi tape


It is understood that , before this , WHB new technology has completed three key catalyst for the development of small- scale and pilot , this three main indicators are the key catalyst in the international advanced level. 2012 , researchers also completed a pilot basis in 3100 hours of engineering scale supplementary test and optimize the process parameters and engineering for large device, so that 200,000 tons / year plant is a one-time savings invested 50 million yuan , annual operating cost savings of about 56 million yuan , plant operation safety and economy improved significantly.Masking tape


According to experts, China Nitrogen Fertilizer Industry Association , WHB development of new technologies adopted a " scientific research - Engineering - production of" three-pronged model. China rings more than 60 years of experience developing and engineering technology more than 40 years Haiso catalyst research and development, production and use of the perfect combination of technology , new techniques to solve engineering problems with two key catalyst research and development , new technologies will WHB great device to drive down risk minimum , but also to the security device running economy and higher reliability . With this new technology to build the first set of 220,000 tons / year ethylene glycol plant will be commissioned by the end of 2014 , engineering design and construction of the device is now being successfully advancing.Wholesale masking tape
