Waste ptfe production of special packing materials
A few days ago, China's high-tech industrialization seminar hosted in Beijing the zhejiang pujiang fluorine plastic co. , LTD. , research and development of 'a kind of waste ptfe physical distribution method of production preparation special seal material and seal' project evaluation of scientific and technological achievements.
Party secretary of the Ministry of Science and Technology torch center Zhang Xuguo, ministry of personnel exchange center, deputy party secretary Chen xin, director of the China petroleum and chemical industry federation researcher professor Cao Zhide, China council for the chemical industry to learn new material jia-yue sun zhi-gang huang, plastic processing and application of light industry research institute professor, China chemical industry group co. , LTD. , a professor at FuZhiXia, professor Du Haiyan Beijing industry and commerce university institute of chemical industry experts participated in the evaluation result.
Evaluation committee to the unit of the completion of the project technical summary report, a review of relevant information, after inquiry to discuss the thought: the project's main innovations and features used waste ptfe physical distribution of magnesium oxide, glass fiber production special sealing ring (
Sealing ring (
Material has high and low temperature resistance, chemical corrosion resistance, high mechanical strength, good sealing performance and low cost;
The product by the national chemical building materials quality supervision and inspection center testing, various technical indicators in line with the Q/PFSS.
2003 standard requirement.
By several users use the technology products, reflect the good and has good economic and social and environmental benefits, the application prospect.
The technology with independent intellectual property rights, has won a Chinese invention patents authorization.
At the same time, the evaluation commission said the project product technology reached the international advanced level and suggested to speed up the industrialization process, meet the market demand.
It is understood that in recent years, the rapid development of the domestic manufacturing, due to the market for polytetrafluoroethylene high and low temperature resistant seal gasket material product demand is very big, especially high and low temperature resistant ball valve door products, in wenzhou, zhejiang province, yongkang, fuyang, tonglu, shaoxing, jiaxing, ningbo, hangzhou and other manufacturers of the product demand is increasing rapidly.
In particular, the country's largest production base in wenzhou valve, the domestic market share of 20%, over the years, the amount of supply and demand has been rapidly increased.
Especially use temperature above 320 ℃ sealing ring (
At home and blank, basically rely on imports.
