Melt Blown Tsis Woven Die-cov cuab yeej tseem ceeb ntawm cov khoom siv ntsej muag

Cov yaj lub ntsej muag yog lub nruab nrab txheej ntawm lub npog ntsej muag. Lub taub fiber ntau tsuas yog ib-kaum-plaub ntawm lub taub hau. Yog li, nws tuaj yeem lim kev sib kis ntawm cov kab mob thiab tus kabmob. Nws yog hu ua "plawv" ntawm daim npog ntsej muag. Tus nqi ntawm melt-blown daim ntaub ntau lawm cov khoom siv yog feem ntau ob peb lab, thiab cov kab ntau lawm txawm yog kaum tawm lab tus, thiab nws yuav tsum muaj kev cob qhia tshwj xeeb rau cov neeg ua haujlwm, thiab qhov pib ntawm kev lag luam yog siab dua. Hauv tshwj xeeb, cov tub ntxhais tseem ceeb ntawm cov kab ntau lawm, yaj ntsej muag tuag lub taub hau thiab spinnerets, tsis muaj

Kev thev naus laus zis ntawm thev naus laus zis ua rau nws los nyuaj rau txoj haujlwm no tseem ceeb.

Qhov ntsuas meej ntawm aperture kev ua haujlwm yog siab. Cov hluav taws xob cheeb ntawm cov ntaub melt-blown yog 0.5 mus rau 10 microns. Thaum lub sij hawm txheej txheem extrusion ntawm spinneret qhov, qhov teeb tsa zoo ib yam thiab kev ruaj ntseg ntawm lub taub hau tuag ua si lub luag hauj lwm txiav txim siab nyob rau hauv cov khoom ntawm lub suab yaj. Nyob rau hauv cov txheej txheem ntawm 1.6-meter dav-hais lus lub ntsej muag tuag lub ntsej muag tuag, ntau dua 2500 qhov yuav tsum tau xuas nrig ntaus hauv lub cev tuag

Txoj kab uas hla, nws ntom thiab teeb tsa sib txawv muaj nruj raws kev cai. Qhov yuam kev ntawm txhua lub aperture yog li 0.3MM. Qhov yuam kev tsis dhau 2%: lub aperture tiav yog 0.01um-0.03um kom mus txog qib iav, thiab tsis tuaj yeem tsis muaj qhov tsis sib xws hauv kev ncaj. Jingwei engineer pab pawg, lub nras muaj ntau tshaj kaum xyoo ntawm kev paub txuj ci

Kev siv cov kev tawm ntawm micro-tawm qhov kawg, ua ke nrog cov tshuab ua kom raug qhov tseeb ntawm qhov chaw tsim khoom ntawm spinnerets rau cov khoom siv hluavtaws tau ntau xyoo, tau txhim kho qhov kev hloov pauv ntawm thev naus laus zis.
