PVA technology to seize the high ground
Guangwei Chemical inception , we determined to seize the world polyvinyl alcohol (PVA) commanding heights of industry technology development , the first to explore the road of sustainable development goals PVA . After the reorganization of broad -dimensional chemical, planning extensive use of local biomass resources ( sugarcane , potato crop ) production of PVA, the most difficult and critical point in this process route is how to take alcohol dehydration of ethylene , vinyl acetate with ethylene production ester , which is a worldwide problem , there is no ready-made production equipment and technology can learn and use. Under such circumstances, the company in cooperation with Tianjin University of Petroleum & Chemical Technology Development Center , developed the world's first ethanol production plant made of vinyl acetate . After three years of design , feasibility studies, equipment selection, installation, commissioning and construction of the building , in September 2012 , invested 750 million yuan of alcohol - ethylene - vinyl acetate - polyvinyl alcohol " 5105 " project basically put into operation by the end of December amounted to production standards . So far, the world's first advanced ethanol made of polyvinyl alcohol by the laboratory to the process line industrialized production .
VAE introduce reform process
In efforts to promote the " 5105 " project at the same time , wide -dimensional chemical clutching VAE ( vinyl acetate - ethylene copolymer emulsion ) production of energy saving, the technological transformation of enterprises into production as lower costs, enhance safety and environmental protection , in a bid to achieve economic operation task, and achieved good social and economic benefits.
VAE technology is used in the production of the reactor and other key equipment from the company in 2006 the company introduced the American Frobo are imported from the United States and other developed countries , is the three VAE introduce the most advanced production line one, its production technology and Frobo company at the same level .Masking tape
After the re-establishment of Guangwei Chemical Company bold leadership and technical personnel to carry out technological transformation of imported production equipment , has invested more than 1,500 yuan, the ethylene plant exhaust and VAE exhaust recovery , reconstruction and ethylene pump circulating water system materials, stopped ethylene plant , purchased ethylene production. These modification measures to make tons of VAE decrease the total cost of technical innovation over the previous 1,000 yuan , but also significantly reduce air pollution and protect the environment. Especially VAE exhaust gas recycling technology projects, technical innovation exhaust discharged before the torch burned , put them continue to invest in the technological transformation VAE recycling production , which saves cost , but also eliminates the noise disturbing phenomenon , but also reduce atmospheric pollution , the project won the Guangxi Zhuang Autonomous Region outstanding Employee Award for innovation and outstanding achievements in technological innovation award national workers . After the " 5105 " project was officially put into operation, the company has weak links for technical innovation , make tons of PVA steam consumption dropped about 7 tons. Preparation of acetic acid , especially PVA produced from recycled material produced in the birth of new product sodium acetate .
New targeted specifically for feeding
In new product development, Guangwei Chemical also increased support. Encourage technical staff to develop ideas, bold ideas , the company allowed to fail, not quit, which greatly stimulated the development of new products, technical staff enthusiasm and creativity . They have developed the GW-707H, GW6001 , etc. 6 VAE emulsion new products, including GW-70228 is a terpolymer products to fill the gap. VAE emulsion product variety increased from 5,6 to now over 10 . Multi -dimensional wide variety of chemical products to seize the market , sales annually .Washi tape
In the " 5105 " project , based on the year the company also has developed a PVB ( polyvinyl butyral ) film and PVA optical film material designed for PVA products by European, American and Japanese customers, they had come to Guangwei Chemical investigate or take samples back to the trial , has reached a preliminary cooperation intention.Sellotape
