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 hau 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 dav kuj siv nws cov shearing thiab thermal degradation los txo qhov hnyav molecular ntawm polymer.
