Kev siv tshuab yaj-blown nonwovens - ob-component yaj-blown technology
Ob-component yaj-blown technology, suav nrog tawv core hom, parallel hom, triangle, thiab lwm yam, feem ntau ze rau 2 qhov loj me fiber, yaj-blown spinneret sib dhos qhov tus lej tuaj yeem ncav cuag 100 qhov ib nti, txhua qhov extrusion peev xwm tuaj yeem ncav cuag 0.5g / min.
Cov khoom siv fiber ntau ob-component yaj tuaj yeem ua kom tiav qhov kev ua tau zoo ntawm ib qho polymer, xws li polypropylene pheej yig heev, tab sis rau cov ntaub ntawv kho mob, nws tsis tiv taus kev raug hluav taws xob, yog li polypropylene ua lub hauv paus, nyob rau hauv txheej sab nraud ntawm cov polymer tiv taus hluav taws xob tsim nyog qhwv rau sab nraud tuaj yeem daws qhov teeb meem ntawm kev tiv thaiv hluav taws xob.
Qhov no ua rau cov khoom pheej yig thiab ua tau raws li qhov yuav tsum tau ua haujlwm, xws li cov cua sov thiab av noo rau lub cev ua pa hauv kev kho mob, uas tuaj yeem muab cua sov thiab av noo zoo ib yam li cua sov thiab av noo ntuj. Nws yog lub teeb yuag, pov tseg lossis yooj yim rau kev tua kab mob, pheej yig, thiab kuj tuaj yeem ua haujlwm ua lub lim dej ntxiv kom tshem tawm cov pa phem. Nws tuaj yeem ua los ntawm ob lub mesh fiber sib xyaw ua ke ob-component yaj-blown.
Txais yuav cov tawv nqaij hom ob feem fiber, lub plawv yog polypropylene, lub cortex yog nylon. Ob-feem fibers kuj tuaj yeem ua rau hauv cov ntu tshwj xeeb, xws li trilobes lossis polylobes, kom nce lawv thaj chaw, thiab polymers kuj tuaj yeem siv rau hauv qhov chaw lossis qhov taub kom txhim kho kev ua haujlwm lim dej. Lub olefin lossis polyester melt-blown ob-component fiber mesh tuaj yeem siv rau cylindrical kua thiab roj lim. Melt-blown ob-component fiber net kuj tuaj yeem siv rau lub taub lim luam yeeb; Siv cov nyhuv nqus tseem ceeb los ua cov pellets nqus kua qib siab; Lub pas nrig nqus tseem ceeb thiab lwm yam.
Kev siv tshuab yaj-blown nonwovens - Melt-blown nanofibers
Yav dhau los, kev tsim cov fiber meltblown yog raws li cov thev naus laus zis patented ntawm Exxon, tab sis nyob rau xyoo tas los no, kev txhim kho thoob ntiaj teb tau tawg los ntawm Exxon thev naus laus zis mus rau cov fiber nanoscale zoo dua.
Vim yog cov qhov me me ntawm cov khoom siv yaj-blown rau kev sib hloov nano fibers, cov zis yuav raug txo qis heev yog tias tsis muaj kev ntsuas. Yog li ntawd, nws yog qhov tsim nyog los nce tus naj npawb ntawm cov qhov ntawm spinneret orifices thiab muab ntau yam khoom sib xyaw ua ke (nyob ntawm qhov dav) ua ke, kom cov zis tuaj yeem nce ntxiv ntau thaum lub sijhawm sib hloov.
Vim tias cov spinnerets nyias nyias uas muaj qhov loj thiab kim heev thiab yooj yim tawg (tawg thaum cua sov hauv qab siab), cov txheej txheem sib txuas tshiab tau tsim los txhim kho qhov ceev ntawm cov spinnerets kom lawv tsis txhob xau hauv qab siab.
Nano yaj - cov fibers blown tuaj yeem siv ua cov khoom siv lim dej, uas tuaj yeem txhim kho kev lim dej zoo heev. Kuj tseem muaj cov ntaub ntawv qhia tias vim tias cov fibers hauv nanometer meltblown nonwovens zoo dua, sib dua thiab sib dua meltblown nonwovens tuaj yeem siv los sib xyaw nrog cov ntaub spunbonded, uas tseem tuaj yeem dais tib lub siab ntawm lub taub hau dej, thiab cov khoom SMS ua los ntawm nws tuaj yeem txo qhov feem pua ntawm cov fiber meltblown.
Ob lub ntsiab lus saum toj no yog cov thev naus laus zis yaj-blown nonwovens, peb yog cov kws tshaj lij yaj-blown nonwovens chaw tsim khoom, Huizhou Jinhaocheng nonwovens Co., Ltd. Kuv vam tias tsab xov xwm no tau muab lub tswv yim rau koj ntawm yaj-blown nonwovens.
