Hangzhou Jinlong Membrane Material Technology Co., Ltd.
The core technology of sponge-like pore structure membrane pores combines high filtration accuracy (0.03 microns) and high water flux.
The modified thermal spinning process and the innovative technology of high crystallinity enhancement achieve high toughness, high tensile elongation at break and high mechanical strength of the membrane material, ensuring no filament breakage under harsh operating conditions or cleaning conditions.
Core technology of in-situ superhydrophilic modification, superhydrophilicity, and excellent anti-pollution performance.
