Meltblown cloth equipment meltblown cloth process flow

1. Polymer pub mis. Lub polymer feem ntau yog ua rau me me kheej kheej thiab granular slices, ncuav rau hauv lub thoob los yog hopper, thiab nkag mus rau hauv cov ntsia hlau extruder.

2. Melt extrusion. Thaum noj kawg ntawm cov ntsia hlau extruder, cov chips polymer yuav tsum tau tov nrog cov khoom ntxiv thiab lwm yam khoom siv raw. Tom qab tag nrho stirred thiab tov, nws nkag mus rau hauv lub ntsia hlau extruder thiab yog rhuab mus rau ib tug yaj. Thaum kawg, cov yaj yog pub rau hauv spinneret los ntawm lub metering twj tso kua mis los ntawm lub lim board. Nyob rau hauv cov txheej txheem yaj yaj, cov extruder dav siv nws cov shearing thiab thermal degradation los txo qhov hnyav molecular ntawm polymer.

3. Fiber tsim. Cov dej huv huv lim los ntawm kev tshuaj ntsuam-hloov lim dhau los ntawm kev faib khoom, thiab tom qab ntawd muab sib npaug rau hauv txhua pab pawg ntawm spinnerets, kom cov nyiaj extrusion ntawm txhua qhov spinneret yog sib xws (yog nws zoo li ntau kab noj hniav kub khiav ntawm txhaj tshuaj molding?). Lub spinneret ntawm melt-blown fiber yog txawv los ntawm lwm yam spinning web txoj kev. Lub qhov spinneret yuav tsum tau teem nyob rau hauv ib txoj kab ncaj nraim, thiab lub siab ceev airflow txhaj qhov yog qhib rau sab sauv thiab sab.
