Melt-blown pp (polypropylene) yog ua los ntawm cov khoom siv polypropylene raw, siv cov txheej txheem rheological tswj tau los txhim kho cov kua dej ntawm cov resin thiab qhov hnyav molecular faib, muaj kev ua haujlwm ruaj khov, kev ruaj khov thiab cov kua dej siab, cov pa roj carbon tsawg, kev tiv thaiv ib puag ncig, qhov hnyav molecular faib nqaim, cov ntsiab lus tshauv tsawg, thiab lwm yam zoo, tuaj yeem raws li cov neeg siv khoom xav tau, tuaj yeem tsim cov dej ntws ntawm cov khoom siv polypropylene melt-blown tshwj xeeb hauv 300 ~ 1900 g / 10 feeb. Nyob rau hauv qhov xwm txheej ntawm qhov kub thiab txias siab thiab av noo siab, cov khoom ua tau zoo ruaj khov, cov khoom tsim nyog rau cov txheej txheem melting tsuag tsis-woven molding, yog kev tsim cov khoom siv raw tseem ceeb polypropylene melting tsuag tsis-woven, muaj kev ua tau zoo dua.
Cov khoom siv polypropylene PP yaj yog siv rau hauv cov txheej txheem tsim cov tshuaj yaj thiab siv ua cov khoom siv raw ntawm cov khoom siv yaj uas tsis yog ntaub nrog cov txiaj ntsig zoo heev. Raws li cov khoom siv yooj yim, txoj kev tswj hwm rheology thiab cov thev naus laus zis hloov kho siab heev tau siv los tsim cov khoom siv yaj PP uas muaj cov kua dej ntau heev nrog kev faib tawm molecular nqaim thiab sib npaug.Tuam Tshoj Guangdong Huizhou Jinhaocheng non-woven npuag Co., Ltdyog ib lub chaw tsim khoom qub rau ntau tshaj kaum xyoo, kev tsim khoom ntawmntaub yajnetwork sib xws, yaj-txaus mos mos.
Daim ntaub tsuag yaj yog cov khoom siv tseem ceeb ntawm lub npog ntsej muag. Daim ntaub tsuag yaj feem ntau yog ua los ntawm polypropylene, thiab lub fiber txoj kab uas hla tuaj yeem txog li 1 ~ 5 microns. Nrog ntau qhov voids, cov qauv fluffy thiab muaj peev xwm tiv thaiv kev quav, cov qauv capillary tshwj xeeb ntawm ultrafine fiber ua rau tus lej thiab thaj chaw ntawm cov fiber ntau ntxiv rau ib cheeb tsam, yog li daim ntaub tsuag yaj muaj kev lim dej zoo, tiv thaiv, rwb thaiv tsev thiab nqus roj.
