1. Impahla yeisikhwama sethani lesiqukathi
Izinto ezijwayelekile zifaka phakathi i-polypropylene (PP) ne-polyethylene (PE), okuyizinto zokuqala zokukhetha ukukhiqiza amabhala ngobuningi ngenxa yezakhiwo zabo ezinhle kakhulu zemishini kanye nokumelana nokubola kwamakhemikhali. Ngaphezu kwalokho, kukhona ezinye izinto ezifana ne-polyester nenayiloni ezibuye zisetshenziswe emisebenzini ethile.
I-Polypropylene (PP)
I-Polypropylene (PP) inamandla amahle kakhulu okudonsa kanye nokumelana nokuhuzuka, okwenza isikhwama sethani lesiqukathi sigcine ukuqina kwesakhiwo futhi singabi lula ukuphuka lapho silayisha futhi sithutha imithwalo esindayo. Ukungangeni kwayo kwamakhemikhali kwenza i-PP imelane kahle nama-asidi amaningi, ama-alkali nezincibilikisi eziphilayo, okuyenza ifanele ukupakishwa kwemikhiqizo yamakhemikhali. Ngaphezu kwalokho, ukuminyana okuphansi kwe-PP kuyenza ibe lula, iphatheke kalula futhi igcinwe. I-PP iphinde ibe nokusebenza okuhle kokucutshungulwa, futhi ingacutshungulwa ibe yiziqukathi zomumo nokucaciswa okuhlukahlukene ngokusebenzisa izinqubo zokuluka, zokuhlanganisa nokuthunga, ukuze kuhlangatshezwane nezidingo zamakhasimende ahlukene. Ukumelana nokushisa kwayo nokumelana nokuguga nakho kwenza i-FIBC eyenziwe nge-PP ifanele ukusetshenziswa isikhathi eside ezimweni ezihlukahlukene zezulu. I-PP ihambisana nemvelo futhi iyasebenziseka futhi, kodwa kusadingeka ukunaka ukwehlisa umthelela endaweni ezungezile ekukhiqizeni nasekugayweni kabusha.
I-Polyethylene (PE)
Enye yezinzuzo ezinkulu ze-polyethylene (PE) ukuguquguquka kwayo okuhle kakhulu kanye nokumelana nomthelela, okuvumela amabhali amaningi ukuthi amunce amandla omthelela ngesikhathi sokulayisha nokuthuthwa, okunciphisa ingozi yokuphuka. Ukungangeni kwayo kwamakhemikhali kwenza i-PE imelane kahle nama-asidi amaningi, izisekelo, nosawoti, okuyenza ilungele ukusetshenziswa ekugcineni nasekuthuthweni kwamakhemikhali. Ukusebenza kwezinga lokushisa eliphansi kwe-PE kungcono kunokwe-PP, futhi kusengakwazi ukugcina ukuqina okuhle ezindaweni ezibandayo futhi akuthambekele ekubeni brittleness. Ukuminyana okuphansi kwe-PE kwenza amabhali amaningi enziwe ngayo alula ngesisindo futhi kube lula ukuwaphatha nokusebenza. I-PE futhi inokumelana okuhle nokuguga, futhi ngokungeza ama-antioxidants kanye neziqinisi ze-UV, inganweba impilo yesevisiizikhwama zamathani esitsheni.
2 Inqubo yokukhiqiza yephakethe lenqwaba
Inqubo yokweluka
Inqubo yokweluka ingenye yezixhumanisi ezibaluleke kakhulu ohlelweni lokukhiqizaizikhwama zamathani esitsheni, edlala indima enqumayo emandleni nasekuqineni kwayo, isebenzisa i-polypropylene (PP) noma i-polyethylene (PE) njengento eyinhloko, eyenziwa ngezintambo eziyisicaba ngenqubo yokudweba ucingo, bese lezi zintambo eziyisicaba zenziwa zibe yizindwangu zisebenzisa i-loom eyindilinga. Ukuminyana kokweluka kanye nendlela yokweluka kuthinta ngqo izakhiwo ezingokomzimba zesikhwama sethani lesitsha. Ukweluka okunobukhulu obuphezulu kungathuthukisa amandla okuqina kanye nokumelana nokugqoka kwamabhala amaningi, kodwa ngesikhathi esifanayo, kwandisa inani lempahla esetshenzisiwe kanye nezindleko zokukhiqiza. Ukuze kuzuzwe ukusebenza okuhle kakhulu, ukuminyana kokuluka okunengqondo nezindlela zokuluka, njenge-plain weave kanye ne-satin weave, ngokuvamile zisetshenziselwa ukuzuza ibhalansi phakathi kwamandla nezindleko. Enkambweni yokweluka, kuyadingeka futhi ukunaka ukufana nokuzinza kwenqubo yokweluka ukuze kugwenywe amaphutha angalingani kanye nendwangu, okuzonciphisa umthamo wokuthwala kanye nempilo yesevisi yesikhwama se-container ton.
Inqubo yokumboza
Ukusebenzisa inqubo yokugqoka, i-polypropylene (PP) noma i-polyethylene (PE) impahla ifakwe ebusweni bendwangu eboshwe ngokusebenzisa imishini ye-extrusion ukuze yenze ifilimu efanayo, engavimbela ngokuphumelelayo ukungena komswakama namakhemikhali, ukuze kuvikelwe impahla ngaphakathi. Enkambweni yokumboza, ukushuba kanye nokufana kwe-coating yimingcele yokulawula eyinhloko. Izingubo eziwugqinsi zingathuthukisa ukumelana kwamanzi namakhemikhali, kodwa zandise inani nezindleko zezinto; I-coating encane ingase inganikezeli ukuvikeleka okwanele. Ukuze kuzuzwe imiphumela emihle kakhulu, ukujiya kokumboza nokufana kufanele kulawulwe ngokuqinile phakathi nenqubo yokukhiqiza. Ukusebenzisa imishini ye-extrusion ethuthukisiwe kanye nesistimu yokulawula okuzenzakalelayo, inqubo yokugqoka enembayo ephezulu ingenziwa.
