Recently, Hengyi Petrochemical Co., Ltd. Zhejiang Hengyi R & D Center independent project, self-developed titanium catalyst polyester chips in the 2000 tons / year continuous trial of successful production.
Hengyi non-antimony green polyester product trademark registration as 'Yi Titanium Kang', with complete independent intellectual property rights. This is Heng Yi in the domestic counterparts in the first successful development and antimony-based catalyst products of the same quality filament grade antimony Environmentally friendly polyester products.
Innovation is the first impetus to lead the development of green non-antimony polyester as a key research and development projects in order to meet the country's development plan of building green production and consumption as well as the concept of creating a better life through scientific and technological innovation.
Through the use of a new coordination chemical structure of the titanium catalyst and the composite catalytic system, Heng Yi R & D team more than two years of repeated small test, pilot, continue to explore and adjust and optimize the production process, and ultimately reached a stable and controllable production process, The indicators of the products are in line with the requirements of polyester chips GB and enterprise standards, and have the conditions for continuous industrial production.
As a new type of environment-friendly fiber-based polyester products, 'Yitai Kang' products have now entered the trial phase of the user to promote the trial, there are many downstream users have a very strong interest in the product.
Antimony-based catalysts commonly used in traditional polyester production have many disadvantages:
1, in polyester polycondensation reaction, antimony catalyst will be partially reduced to gray.
2, the synthesis of polyester spinning, due to the reduction of heavy metals accumulation will increase the pressure on the spinning components.
3, heavy metal antimony has some toxicity, not only precipitated in the PET dyeing process resulting in environmental pollution, PET terminal products into garbage also also bring 10,000 tons of annual antimony into nature, resulting in non-recoverable pollution.
As a leader in the polyester industry, Hengyi has long been committed to contributing to the cause of environmental protection. The successful research and development of non-antimony environmental Polyester products' Yi Titanium Kang 'is Hengyi in-depth practice' Green Water Castle Peak is Jinshan Yinshan 'new concept of specific portrayal of non-antimony environmentally friendly polyester products' Yat Tianyang' in the Heng Yi polyester device production line of the full promotion, will set off a revolution in the polyester industry, and effectively contribute to the development of China's green Heng Yi power.
