Ukusebenza kwemikhiqizo encibilikisiwe ngokuyinhloko kubhekisela ezintweni zayo ezingokomzimba neziwumshini, njengamandla, ukuphefumula, ububanzi befayibha, njll. Ngenxa yobunkimbinkimbi benqubo yokuncibilika kokuncibilika, kunezici eziningi ezinomthelela. Namuhla, umhleli uzohlaziya kafushane izizathu zokuntuleka kokuqina kwezindwangu ezincibilikayo. Uma ungeke ukwazi ukuyichaza kahle, sicela unikeze isiqondiso neziphakamiso ezengeziwe!
Ncibilikisa i-polypropylene PP yebanga lezinhlayiyana zezinto ezingavuthiwe
Inkomba yokuncibilika (i-MFI) yezinhlayiya ze-polypropylene ihlobene ngokuqondile namandla aqinile namandla aqhumayo ezindwangu ezincibilikayo ezincibilikayo ezincibilikayo.Isisindo se-molecular ye-polymer siphansi, i- melt flow index (MFI) iphezulu, futhi i-viscosity encibilikayo iphansi, okwenza ifaneleke kakhudlwana kwababuthakathaka.
Ukwelula umphumela ezinqubweni zokuncibilika zokufafaza
Uma iphezulu inkomba ye-ncibilika, amandla e-ncibilika aphephuka i-fiber eyodwa ayancipha namandla ewebhu yefayibha.
Ekukhiqizeni kwangempela, kufanele kusetshenziswe i-polypropylene ene-MFI ephezulu noma i-MFI ephansi?
I-MFI encane: ekwazi ukukhiqiza izindwangu ezingalukiwe ezincibilikayo ezinamandla amakhulu.
I-MFI enkulu: okukhiphayo okuphezulu, ukusetshenziswa kwamandla okuphansi. Ngakho-ke, inkambiso yamanje ukusebenzisa izinto zokusetshenziswa eziphezulu ze-MFI.
Ncibilikisa amapellets e-polypropylene PP ebanga elishisayo: MFI>1500
Okusho ukuthi, uma uthola ukuthi indwangu encibilikisiwe ekhiqizwayo "i-brittle kakhulu", qala uhlole inkomba yokuncibilika kwezinto zokusetshenziswa. Indlela eqondile yokubuka le pharamitha incike ekutheni uthenge kuphi izinto zokusetshenziswa.
Inqubo yokuncibilika efuywayo
Isizathu sokuthi kungani ukugeleza komoya oshisayo kukuncane kakhulu:
Isivinini somoya oshisayo siyenyuka;
Ubukhulu be-fiber ububanzi;
Amandla ahlobene emicu eyodwa ayanda;
Umphumela wokubopha phakathi kwemicu kuwebhu uyanda, futhiamandla endwangu engalukiweiyanda.
Isivinini sokugeleza komoya oshisayo silawulwa phakathi kuka-0.08-0.2. Izinga lokugeleza komoya kufanele libe njalo futhi alikwazi ukuguquguquka ngokushesha. Uma izinga lokugeleza liphezulu kakhulu, lizokwenza into "yokudubula". Ngenxa yezinhlobonhlobo zemishini yokuhlinzeka ngegesi emakethe yamanje kanye nokusebenza okungalingani, izinkinga kufanele ziphathwe ngendlela ehlukile futhi imingcele yenqubo yokuncibilika yokufafaza kufanele ilungiswe kalula.
Izinga lokushisa lekhanda lesikhunta eliphephukayo
Lapho izinga lokushisa liphakeme, i-viscosity yencibilika iyancipha, futhi imicu iyancipha
Kodwa-ke, i-viscosity ephansi yokuncibilika ingabangela ukwelula ngokweqile kwemicu encibilikayo, okuholela emicucu emifushane ne-ultrafine ehlakazeka emoyeni futhi engakwazi ukuqoqwa. Ngakho-ke, i-viscosity yokuncibilika kwe-polymer ekuqhumeni kwenqubo yokuncibilika ayingcono kakhulu uma iphansi. Ezikhathini ezinjengalezi, kungase kube nesenzakalo 'sezimbali ezindizayo', lapho ingekho imicu ehlangene noma ehlakazekile emoyeni.
Izinga lokushisa lekhanda lesikhunta, i-flange, nendololwane kufanele kugcinwe kumugqa weleveli, futhi lawa mazinga okushisa amathathu akumele achezuke kakhulu.
Okungenhla kuwukuhlaziywa kwezizathu zokuthi kungani izindwangu ezincibilikisiwe ziba brittle futhi zibe namandla anganele okuqina. Kuncike emandleni okuqina kwendwangu, futhi inqubo yokukhiqiza kufanele ilungiswe ngokufanele. Ukukhiqizwa kwezindwangu ezincibilikisiwe akunzima, kodwa ubunzima busenqubo yokwenza i-meltblown, edinga inani elithile lokuqoqwa kokuhlangenwe nakho ukulungisa ukusebenza kwemishini. Kubangani abangaqondi ngempela, bangathola umpetha othembekile wokulungisa umshini noma bathinte umhleli ukuze baxoxe futhi bakhuthaze ndawonye!
I-Dongguan Liansheng Nonwoven Fabric Co., Ltd., umkhiqizi wezindwangu ezingezona eziboshwe kanye nezindwangu ezingezona ezilukiwe, ufanelwe ukwethenjwa kwakho!
