Isingeniso esiyisisekelo seIndwangu engalukiwe ye-PPkanye nendwangu engalukiwe ye-polyester
Indwangu engalukiwe ye-PP, eyaziwa nangokuthi i-polypropylene non-woven fabric, yenziwe ngemicu ye-polypropylene encibilika futhi iphothwe emazingeni okushisa aphezulu, epholile, enwetshiwe futhi elukwe ibe yindwangu engalukiwe. Inezici zokuminyana okuphansi, ukungasindi, ukuphefumula, nokukhipha umswakama. Izinga lendwangu engalukiwe ye-polypropylene liphansi futhi intengo ishibhile.
Indwangu engalukiwe ye-polyester, eyaziwa nangokuthi i-polyester non-woven fabric, iyindwangu engalukiwe eyenziwe ngokucubungula imicu ye-polyester ngezinqubo ezihlukahlukene ezifana nokushisa nezithasiselo zamakhemikhali. Inokwelula okuphezulu, ukuqina, ukumelana nokungqubuzana, ukumelana nokushisa, ukumelana nokugqwala, kanye nokushelela. Izinga lendwangu engalukiwe ye-polyester liphezulu futhi intengo iyabiza.
Umehluko phakathi kwendwangu engalukiwe ye-PP nendwangu engalukiwe ye-polyester
Umehluko wezinto ezibonakalayo
Ngokuya ngezinto zokusetshenziswa, i-PP ibhekisela ku-polypropylene, eyaziwa nangokuthi i-polypropylene; I-PET ibhekisela ku-polyester, eyaziwa nangokuthi i-polyethylene terephthalate. Amaphuzu okuncibilika emikhiqizo emibili ahlukile, i-PET inephuzu lokuncibilika elingaphezu kwama-degree angu-250, kanti i-PP inephuzu lokuncibilika elingu-150 degrees kuphela. I-polypropylene imhlophe uma kuqhathaniswa, kanti imicu ye-polypropylene inomthamo ophansi kunemicu ye-polyester. I-Polypropylene ine-asidi ne-alkali kodwa ayimelani nokuguga, kuyilapho i-polyester imelana nokuguga kodwa ayinayo i-asidi ne-alkali. Uma ngemva kokucubungula kwakho kudinga ukusetshenziswa kwehhavini noma izinga lokushisa elingaphezu kuka-150 degrees Celsius, i-PET ingasetshenziswa kuphela.
Umehluko wenqubo yokukhiqiza
Indwangu engalukiwe ye-polypropylene icutshungulwa ngokusebenzisa ukuphotha okuncibilika okuphezulu okuncibilika, ukupholisa, ukwelula, kanye nenetha ibe yindwangu engalukiwe, kuyilapho indwangu ye-polyester engalukiwe icutshungulwa ngezinqubo ezihlukahlukene ezifana nokushisa kanye nezithasiselo zamakhemikhali.Ngokwezindlela zokukhiqiza nezindlela zokucubungula, lezi ezimbili zinokufana kanye nokwehluka. Izindlela zokucubungula ezihlukene zivame ukunquma isicelo sokugcina. Uma sikhuluma nje, i-PET isezingeni eliphezulu futhi iyabiza. Indwangu engalukiwe ye-PET polyester ine: okokuqala, ukuzinza okungcono kunendwangu engalukiwe ye-polypropylene, ebonakaliswa ngokuyinhloko ngamandla, ukumelana nokugqoka nezinye izakhiwo. Ngenxa yokusetshenziswa kwezinto ezikhethekile zokusetshenziswa kanye nemishini ethuthukisiwe evela kwamanye amazwe, kanye nezindlela zokucubungula eziyinkimbinkimbi nezesayensi, indwangu ye-polyester engalukiwe idlule kude okuqukethwe kobuchwepheshe kanye nezidingo zendwangu engalukiwe ye-polypropylene.
Umehluko wesici
Indwangu engalukiwe ye-Polypropylene inezici zokuminyana okuphansi, isisindo esingasindi, ukuphefumula, nokukhipha umswakama, kuyilaphoi-polyester engalukiwe indwanguinokunwebeka okuphezulu, ukuqina, ukumelana nokushisa, ukumelana nokugqwala, nokushelela. I-PP inokumelana nokushisa okuphezulu okungama-degree angu-200, kuyilapho i-PET inokumelana nokushisa okuphezulu okungama-degree angu-290, futhi i-PET imelana kakhulu nokushisa okuphezulu kune-PP. Ukuphrinta okungalukiwe, umphumela wokudlulisa ukushisa, i-PP enobubanzi obufanayo incipha kakhulu, i-PET incipha kancane futhi inomphumela ongcono, i-PET iyonga kakhulu futhi ayimoshi kangako. Amandla aqinile, ukungezwani, amandla okuthwala umthwalo, nesisindo esifanayo, i-PET inamandla amakhulu okudonsa, ingcindezi, namandla okuthwala umthwalo kune-PP. Amagremu angu-65 we-PET alingana namandla aqinile, ukushuba, namandla okuthwala umthwalo angama-80 amagremu we-PP. Ngokombono wemvelo, i-PP ixubene nemfucuza ye-PP egaywe kabusha, kuyilapho i-PET yenziwe ngokuphelele ngamachips e-polyester amasha, okwenza i-PET ihambisane nemvelo futhi ibe nenhlanzeko kune-PP.
Indwangu engalukiwe ye-PP inokuminyana okungu-0.91g/cm kuphela, okuyenza ibe uhlobo olulula kakhulu phakathi kwemicu yamakhemikhali evamile. Uma i-polyester engalukiwe indwangu i-amorphous ngokuphelele, ukuminyana kwayo kungu-1.333g/cm. Indwangu engalukiwe ye-PP inokumelana nokukhanya okubi, ayimelani nokukhanya kwelanga, futhi ijwayele ukuguga kanye nokuba brittleness. Indwangu engalukiwe ye-polyester: Inokumelana okuhle nokukhanya futhi ilahlekelwa kuphela u-60% wamandla ayo ngemva kwamahora angu-600 okukhanya kwelanga.
Izimo zohlelo lokusebenza ezahlukene
Lezi zinhlobo ezimbili zezindwangu ezingalukiwe zinomehluko omkhulu ekusetshenzisweni, kodwa zingashintshana kwezinye izici. Kunomehluko kuphela ekusebenzeni. Umjikelezo wokulwa nokuguga wezindwangu ezingezona ezilukiwe ze-polyester uphakeme kunalowo weizindwangu ezingezona ezilukiwe ze-polypropylene. Izindwangu ezingezona ezilukiwe ze-polyester zisebenzisa i-polyvinyl acetate njengempahla eluhlaza, futhi amelana nebhu, imihuzuko nemisebe ye-ultraviolet. Izici ezingenhla ziphakeme kunezindwangu ezingezona ezilukiwe ze-polypropylene. Uma kuqhathaniswa ne-polypropylene nezinye izindwangu ezingalukiwe, i-polyester engalukiwe inezinto ezinhle kakhulu njengokungamunzi, ukumelana namanzi, nokuphefumula okuqinile.
Isiphetho
Kafushane, indwangu engalukiwe ye-polypropylene nendwangu engalukiwe ye-polyester yizinto ezimbili ezivame ukusetshenziswa ezingezona ezilukiwe. Nakuba kunomehluko othile ezintweni zokwakha, izinqubo zokukhiqiza, nezici, nawo anomehluko ezimeni zohlelo lokusebenza. Kuphela ngokukhetha izinto ezifanele zendwangu ezingalukiwe ezisekelwe ezidingweni ezithile lapho singahlangabezana kangcono nezidingo zokukhiqiza.
I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakwazi ukukhiqiza imibala ehlukahlukene ye-PP spunbond izindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
