Kev Txheeb Xyuas ntawm Kev Txhim Kho Kev Txhim Kho ntawm Melt-blown Txheej rau PP Qhuav Cua Lim Cartridge Tshuab

PP yaj blown lim cartridge tshuab yog ib qib high-zoo PP yaj-cua daj lim tub ntxhais los ntawm cov txheej txheem melt-blown. Cov qauv ntawm cov tub ntxhais lim dej no yog tuab txheej txheej fiber ntau, nplua puab txheej fiber ntau, xoob sab txheej, thiab nruj gradient qauv ntawm puab txheej. . Qhov cim gradient tob pom cov ntaub ntawv muaj cov xim lim dej uas muaj peb sab hauv, featuring siab porosity, siab rejection, muaj peev av loj tuav, khiav ceev thiab tsis tshua muaj siab.

Lub txheej yaj-cua tshuab yog ib qho ntawm cov txheej txheem txheej txheem ntawm lub polymer. Hauv kev tshawb xav, tag nrho cov thermoplastic polymer chipstock cov ntaub ntawv yuav siv tau rau hauv cov txheej txheem ntawm cov yaj-tshuab lim. Polypropylene yog ib qho ntawm feem ntau siv slicing cov ntaub ntawv nyob rau hauv lub melt-blown txheej txheem. Tsis tas li ntawd, cov ntaub qhwv polymer slicing feem ntau siv nyob rau hauv cov txheej txheem melt-blown yog polyester, polyamide, polyethylene, polytetrafluoroethylene, polystyrene, PBT, EMA. , EVA, lwm yam.

Lub polymerization degree ntawm olefin polymer raw khoom siab heev, kom lub cua kub kub siab tshaj qhov nruab nrab ntawm 100 ° C ntawm lub kub dua, thiab cov cua kub lub polyester yog me ntsis siab tshaj qhov nruab nrab ntawm qhov chaw ntawd qhuav cua tshuab. Ostenic feedstocks feem ntau tsis xav kom qhuav. Cov yam ntxwv ntawm cov qauv hauv PP lub tshuab cua tshuab lim cov cav tov yog cov fibro fiber ntau, feem ntau tsawg dua 10 microns, thiab feem ntau ntawm cov kua fiber ntau ntawm 1 thiab 4 microns.
