Meltblown Nonwoven Fabric Production Process

Meltblown nonwoven fabric yog ib hom ntaub uas tsim los ntawm cov txheej txheem yaj-tshuab. Nyob rau hauv cov txheej txheem melt-blowing, polymers yog melted ntawm high tshav kub thiab sprayed los ntawm me me qhov los tsim fibers, uas yog ces tsim rau hauv ib tug net-zoo li qauv siv cua los yog mechanical siab.

Kev tsim cov txheej txheem ntawm meltblown nonwoven npuag tuaj yeem tawg ua ob peb kauj ruam tseem ceeb.

● Kev npaj khoom. Thaum xub thawj, cov ntaub ntawv polymer xws li polypropylene thiab polyester yuav tsum tau sib sau ua ke thiab raug cua sov thiab yaj kom hloov mus rau hauv cov kua molten.

● Melt txhaj tshuaj. Molten polymer yog txhaj los ntawm cov tshuaj tsuag nozzles, qhov twg lub nozzle qhov loj thiab kev teeb tsa cuam tshuam cov fibers daim ntawv thiab kis tau. Cov fibers raug tshem tawm ntawm kev kub ceev thiab maj mam txias thiab tawv thaum lawv txav los ntawm huab cua.

● Fiber tsim. Cov molten polymer fibers maj mam tsim cov qauv mesh zoo li hauv huab cua. Qhov no tshwm sim raws li cov fibers raug tshem tawm thiab cuam tshuam los ntawm huab cua tiv thaiv thiab kev sib tsoo, ua rau lawv cuam tshuam thiab tsim lub vev xaib.

● Thermal roller shaping. Thaum cov fibers raug tsim, lawv zoo li siv thermal rollers, uas tsis tsuas yog ua kom lub zog ntawm fiber ntau mesh tab sis kuj kho cov ntaub thickness. Qhov kub thiab siab ntawm cov chais yuav tsum tau tswj raws li cov kev cai tshwj xeeb.

● Txheej kev kho mob. Thaum lub sij hawm zus tau tej cov melt-blown nonwoven ntaub, ib txheej kho kuj yuav siv tau. Cov txheej no txhim kho cov ntaub ua haujlwm, xws li ua kom tsis muaj dej tsis zoo lossis tiv thaiv zoo li qub. Txheej txheej feem ntau ua tiav tom qab thermal roller shaping txheej txheem.

● Cua thiab txiav. Cov kauj ruam kawg ntawm cov txheej txheem yuav tsum winding lub meltblown nonwoven ntaub rau hauv yob thiab txiav nws mus rau qhov loj me. Winding simplifies cia thiab thauj, thaum txiav kom cov ntaub yog me me raws li specifications.

Cov txheej txheem tsim khoom ntawm meltblown nonwoven npuag muaj ntau qhov zoo, suav nrog cov hauv qab no:

1. Ua tau zoo thiab ceev ceev. Cov txheej txheem meltblown enables high-speed, nruam ntau lawm, kom ntseeg tau siab efficiency.

2. Fiber fineness yog tswj tau. Los ntawm kev kho cov kab thiab kev teeb tsa ntawm lub nozzles, fiber ntau fineness ntawm meltblown nonwoven npuag tuaj yeem tswj tau kom tau raws li ntau yam kev thov.

3. Uniform mesh qauv. Los ntawm cov txheej txheem melt-blowing, fibers muaj peev xwm tsim thiab interlace dawb nyob rau hauv cov huab cua, tsim ib tug tusyees faib mesh qauv.

4. Ntau yam hauv kev ua haujlwm. Los ntawm cov txheej txheem zoo li txheej, yaj-blown nonwoven npuag tuaj yeem muab cov yam ntxwv ntxiv, suav nrog dej tsis kam thiab muaj peev xwm tiv thaiv zoo li qub.

5. Lub teeb thiab mos. Meltblown nonwoven npuag, nrog nws cov fibers zoo, yog tus cwj pwm los ntawm kev sib sib zog nqus thiab mos, ua rau nws zoo tagnrho rau cov khoom lag luam uas nyiam kev nplij siab.

Meltblown nonwoven npuag yog ntau yam thiab pom cov ntawv thov thoob plaws ntau yam kev lag luam. Nws yog siv rau hauv kev kho mob los tsim cov khoom tiv thaiv zoo li lub qhov ncauj qhov ntswg thiab lub tsho, hauv tsev textiles xws li ntaub pua chaw pw thiab ntaub, thiab hauv kev siv hauv kev lag luam xws li pom thiab txo cov suab nrov.

Cov txheej txheem meltblown yog cov cuab yeej siv tau zoo thiab nrawm rau kev tsim cov ntaub tsis muaj ntaub nrog ntau yam haujlwm thiab ntau yam kev siv. Nrog kev txhim kho thev naus laus zis tsis tu ncua thiab nthuav dav ntawm kev siv, lub neej yav tom ntej ntawm cov ntaub yaj-blown nonwoven npuag zoo nkaus li zoo heev.
