iyini impahla ye-spunbond

Kunezinhlobo eziningi zezindwangu ezingalukiwe, futhi indwangu engalukiwe ye-spunbond ingenye yazo. Izinto eziyinhloko zendwangu engalukiwe ye-spunbond i-polyester ne-polypropylene, enamandla amakhulu nokumelana okuhle nokushisa okuphezulu. Ngezansi, umbukiso wendwangu engalukiwe uzokwethula ukuthi iyini indwangu engalukiwe ye-spunbond? yini impahla ye-spunbond? Ake sibheke ndawonye.

Yiniindlela ye-spunbond

Isizathu esibalulekile sokukhula kwayo ngokushesha ukuthi isebenzisa ama-polymers okwenziwa njengezinto zokusetshenziswa. Le ndlela isebenzisa isimiso sokuphotha kwe-chemical filament ukuze iqhubeke ibe umcu phakathi nenqubo yokuphotha i-polymer, ebese ifafazwa kuwebhu futhi iboshwe ngokuqondile ukukhiqiza izindwangu ezingalukiwe. Indlela yokukhiqiza ilula kakhulu futhi iyashesha. Uma kuqhathaniswa nobuchwepheshe bokucubungula indwangu eyomile engalukiwe, iqeda uchungechunge lwezinqubo eziphakathi nendawo eziyisicefe ezifana ne-fiber curling, ukusika, ukupakisha, ukuthutha, ukuxuba, nokuhlanganisa Umphumela obaluleke kakhulu wokukhiqiza ngobuningi ukwenza imikhiqizo ye-spunbond ibe namandla aphezulu, izindleko eziphansi, kanye nekhwalithi ezinzile. Ukwelula kwendlela ye-spunbond kuyinkinga eyinhloko yobuchwepheshe yokuthola imicu emihle ye-denier nezinto ezingezona ezilukiwe ezinamandla, futhi okwamanje indlela eyinhloko ubuchwepheshe bokwelula ukugeleza komoya. Ukuze kuthuthukiswe ukuthuthukiswa okusalungiswa kokugeleza komoya kwemicu ye-spunbond, ukukhishwa okuphakeme kokuphotha kwembobo eyodwa, ukuklanywa kwezimbobo ze-spinneret ezixinene kakhulu, nomthelela wazo ekukhiqizeni naseqophelweni lezinto ezingalukiwe, sifunda ngomklamo wesiteshi esisalungiswa esihlanganisa ukucindezela okuhle kanye nengcindezi engemihle, kanye nomthelela wokuphotha kwe-electrostatic ekujikelezeni kwejubane, ukufana kwewebhu kanye nobubanzi obuhle bewebhu. Lolu uhlobo olukhethekile lwemishini ye-spunbond eyenzelwe ukuthuthukiswa kwezimboni, Omunye wemisebenzi ebalulekile yemishini ye-spunbond enezingxenye ezimbili ezifanayo.

iyini impahla ye-spunbond

Izinto zokusetshenziswa zespunbond izindwangu ezingalukiweikakhulukazi ihlanganisa imicu ye-cellulose nemicu yokwenziwa, eyenziwa ngenqubo ye-spunbond. Inokuzwakala kahle kwesandla, ukuphefumula, nokumelana nokugqoka, futhi isetshenziswa kabanzi emikhakheni ehlukahlukene. Inqubo yokwenziwa kwendwangu engalukiwe ye-spunbond ilula, iyonga, futhi inamathemba abanzi emakethe. Kwethenjwa ukuthi kuzoba nokuqanjwa okusha nokuthuthukiswa esikhathini esizayo, ukuze indwangu engalukiwe ye-spunbond ibambe iqhaza elikhulu emikhakheni ehlukahlukene.

I-cellulose fiber

I-Cellulose fiber ingenye yezinto ezibalulekile zokukhiqiza izindwangu ezingalukiwe ze-spunbond. I-Cellulose iyinhlanganisela yemvelo yemvelo etholakala kabanzi ezindongeni zamaseli ezitshalo. Imicu eminingi yezitshalo, enjengokotini, ilineni, i-hemp, njll., iqukethe i-cellulose eningi. Lezi zitshalo zithola uchungechunge lokwelashwa kokucubungula, njengokucwecwa, ukwehlisa amafutha, nokubilisa, ukuze kukhishwe i-cellulose ezitshalweni. Bese, ngenqubo ye-spunbond, imicu ye-cellulose iyanwetshwa futhi iqondiswe ukuze yenze indwangu engalukiwe ye-spunbond. Imicu ye-cellulose inokuthamba okuhle nokuphefumula, okwenza izindwangu ezingalukiwe ze-spunbond zibe nokuzwakala kahle kwesandla kanye nokuphefumula.

Imicu yokwenziwa

Imicu yokwenziwa ingenye impahla eluhlaza evame ukusetshenziswa ezindwangu ezingezona ezilukiwe ze-spunbond. Imicu yokwenziwa imicu eyenziwe ngokwenziwa kokwenziwa noma ukuguqulwa kwamakhemikhali, njengemicu ye-polyester, imicu yenayiloni, njll. Enqubweni yokukhiqiza izindwangu ezingezona ezilukiwe ze-spunbond, imicu yokwenziwa ivamise ukuxutshwa nemicu ye-cellulose ukuze kuthuthukiswe amandla nokumelana nokugqoka kwezindwangu ezingalukiwe ze-spunbond.

Iyini indwangu engalukiwe ye-spunbond?

Indwangu engalukiwe eyenziwe nge-spunbonded, ikakhulukazi eyenziwe nge-polyester ne-polypropylene, inamandla aphezulu kanye nokumelana okuhle nezinga lokushisa eliphezulu. Indwangu engalukiwe ephothiwe ikhipha futhi yelula amapholymer ukuze akhe imicu eqhubekayo, bese ibekwa kuwebhu. Iwebhu ibe isizibophezela, iboshelwa ngokushisa, iboshwe ngamakhemikhali, noma iqiniswe ngomshini ukuze iguqule ibe yindwangu engalukiwe.

Ukukhethwa kwezinto zokusetshenziswa

Izinto zokusetshenziswa ezisetshenziswa emugqeni wokukhiqiza zihlobene nokuma kwemakethe nenjongo yomkhiqizo. Lapho ukhiqiza imikhiqizo yemakethe esezingeni eliphansi, ngenxa yezidingo eziphansi zezinto ezingavuthiwe, ukuze kuncishiswe izindleko zokukhiqiza, izinto ezingavuthiwe zekhwalithi ephansi zingakhethwa. Okuphambene nakho kuyiqiniso.

Imigqa eminingi yokukhiqiza ye-spunbond nonwoven isebenzisa ama-chips e-polypropylene (PP) eyimbudumbudu njengezinto zokusetshenziswa, kodwa futhi kukhona imigqa emincane embalwa yokukhiqiza esebenzisa izinto zokusetshenziswa eziyimpuphu ze-PP, neminye imigqa yokukhiqiza esebenzisa izinto ezingasetshenzisiwe ze-polypropylene ezigaywe kabusha. Ngokungeziwe ezintweni zokusetshenziswa eziyimbudumbudu, imigqa yokukhiqiza encibilikisiwe engalukiwe ingase isebenzise izinto zokusetshenziswa eziyindilinga.

Intengo yokusika ihlobene ngokuqondile nobukhulu benani layo le-MFI, ngokuvamile inani elikhulu le-MFl, intengo iphakama. Ngakho-ke, kuyadingeka ukuthi kubhekwe kabanzi inqubo yokukhiqiza, izici zemishini, ukusetshenziswa komkhiqizo, intengo yokuthengisa yomkhiqizo, izindleko zokukhiqiza, nezinye izici ukukhetha izinto zokusetshenziswa ezizosetshenziswa.
