Led by Sinochem Blue Sky, Tsinghua University, Beijing Sino Membrane Technology Co.
, Ltd.
and Sichuan National Water Treatment Center jointly participated in the national "863" plan project high-performance separation membrane materials large-scale key technology (phase I) sub-project - high-performance polyvinylidene fluoride (PVDF) material development and application in urban sewage treatment, has passed the acceptance
organized by the Ministry of Science and Technology.
At present, the synthesis technology of PVDF series resin for water treatment membrane has matured, and the performance of industrialized amplified products is stable, which can provide domestic high-performance PVDF series resin for water treatment membrane to replace imported similar products
.
This is not only beneficial to film making and film enterprises to reduce the cost of membrane materials, but also brings considerable economic benefits
to domestic resin enterprises.
This course standard is to meet the needs of advanced treatment and recycling of urban sewage, and develop the high-performance PVDF hollow fiber membrane green manufacturing process technology with independent intellectual property rights.
Build an industrialization base with an annual output of 2 million square meters of hollow fiber membrane and corresponding membrane modules for serial products; Develop a special resin suitable for the preparation of high-performance PVDF film by the TIPS method, improve the anti-pollution ability and service life of the film, and make it reach the international advanced level
.
Through the joint research undertaken, the research group achieved the expected goals, successfully developed PVDF resin products for water treatment membranes, realized the localization of PVDF resin for water treatment membranes, and replaced imported products
。 The project also broke through the technical bottleneck of preparing high-performance PVDF hollow fiber membrane by TIPS method, developed a large-scale, high-precision continuous and stable green advanced manufacturing process, and built the first domestic PVDF hollow fiber membrane production line with an annual output of 2 million square meters, the product performance has reached the international advanced level, successfully replaced the international famous brand products, and the environmental and economic benefits are very significant
