Isingeniso
Ukukhiqizwa kwefilimu ye-Polyethylene (PE) kuyindlela yokukhiqiza esetshenziswa kabanzi yokukhiqiza amafilimu epulasitiki asetshenziswa emaphaketheni, ezolimo nasekwakhiweni. Le nqubo ihilela ukukhipha i-PE encibilikisiwe ngefa eliyindilinga, ukuyifutha ibe yibhamuza, bese ipholisa futhi iyisonge ibe ifilimu eyisicaba. Ukusebenza kahle kubalulekile ekukhiqizeni okungabizi kakhulu kanye nemikhiqizo yokugcina yekhwalithi ephezulu. Kodwa-ke, izinselele ezimbalwa zingavela ngesikhathi sokukhiqiza, njengokungqubuzana okuphezulu phakathi kwezingqimba zefilimu nokuvinjwa kwefilimu, okunganciphisa kakhulu ukusebenza kahle kanye nokwehliswa kwekhwalithi yomkhiqizo.

Lesi sihloko sizohlola izici zobuchwepheshe zefilimu efuthwe yi-PE, sigxile ku-aUkushelela okuhle kakhulu kanye nesengezo sokuvimba ukuvimbanokuthi isiza kanjani ukunqoba izinselele zokukhiqiza ukuze kukhuliswe ukusebenza kahle kukonke kanye nokuthuthukisa ukusebenza kwefilimu.

I-PE Blown Film Production Uhlolojikelele Lwezobuchwepheshe kanye Nezici Ezisebenzayo

Uhlolojikelele lwenqubo ye-Blown Film Extrusion

Inqubo yokukhipha ifilimu eshaywayo iqala ngokuphakelwa kwamapellets e-PE resin ku-extruder, lapho encibilikiswa khona futhi enziwe i-homogenized ngokusebenzisa inhlanganisela yokushisa namandla okugunda. I-polymer encibilikisiwe ibe iphoqeleka ngokusebenzisa isiyingi esiyindilinga, yakha ishubhu eliqhubekayo. Umoya ungeniswa phakathi nendawo yaleli shubhu, uwuvuthele ube ibhamuza. Leli bhamuza libe selidonselwa phezulu, ngesikhathi esifanayo lelula ifilimu kukho kokubili isiqondiso somshini (MD) kanye nesiqondiso esiphambene (TD), inqubo eyaziwa ngokuthi i-biaxial orientation. Njengoba ibhamuza likhuphuka, lipholiswa yindandatho yomoya, okwenza i-polymer icwebezele futhi iqine. Ekugcineni, ibhamuza elipholile ligoqwa yisethi yama-nip rollers futhi alinyazwe kumqulu. Imingcele eyinhloko ethonya inqubo ihlanganisa izinga lokushisa elincibilikayo, igebe lokufa, isilinganiso se-blow-up (BUR), ukuphakama komugqa wesithwathwa (FLH), nezinga lokupholisa.

Izici Eziyinhloko Ezithinta Ukusebenza Ngempumelelo Kokukhiqiza

Kunezici ezimbalwa ezithinta ngqo ukusebenza kahle kokukhiqizwa kwefilimu efuthwe yi-PE:

• Impumelelo: Izinga ifilimu ekhiqizwa ngalo. Ukusebenza okuphezulu ngokuvamile kusho ukusebenza kahle okuphezulu.

• Ikhwalithi Yefilimu: Lokhu kuhlanganisa izici ezifana nokufana kogqinsi, amandla emishini (amandla aqinile, ukumelana nezinyembezi, ukushayisana kwe-dart), izici zokubona (ubungu, ukucwebezela), nezici zangaphezulu (i-coefficient of friction). Ikhwalithi yefilimu ephansi iholela ekwenyukeni kwamazinga e-scrap kanye nokuncipha kokusebenza kahle.

• Isikhathi sokuphumula: Izitobhi ezingahleliwe ngenxa yezinkinga ezifana nokuphuka kwefilimu, ukwakhiwa kwamafasitela, noma ukungasebenzi kahle kwemishini. Ukunciphisa isikhathi sokuphumula kubalulekile ekusebenzeni kahle.

• Ukusetshenziswa kwamandla: Amandla adingekayo ukuze kuncibilike i-polymer, ukusebenzisa i-extruder, namasistimu okupholisa amandla. Ukunciphisa ukusetshenziswa kwamandla kuthuthukisa ukusebenza kahle konke futhi kunciphisa izindleko zokusebenza.

• Ukusetshenziswa Kwempahla Engahluziwe: Ukusetshenziswa kahle kwe-PE resin nezithasiselo, kunciphisa imfucuza.

Izinselelo Ezijwayelekile Zokukhiqiza Amafilimu e-PE Blown

Naphezu kwentuthuko kwezobuchwepheshe, ukukhiqizwa kwefilimu ye-PE kubhekene nezinselelo ezimbalwa ezivamile ezingaphazamisa ukusebenza kahle:

• Ukuvinjwa Kwefilimu: Ukunamathela okungafuneki phakathi kwezingqimba zefilimu, kungaba kumqulu noma phakathi nezinyathelo zokucubungula ezilandelayo. Lokhu kungaholela ebunzimeni bokukhumula, ukwanda kwezinsalela, kanye nokubambezeleka kokukhiqiza.

• I-High Coefficient of Friction (COF): Ukungqubuzana okuphezulu endaweni yefilimu kungabangela izinkinga ngesikhathi sokusonga, ukuqaqa, nokuguqula, okuholela ekunamatheleni, ekubhidlikeni, nasekunciphiseni izivinini zokucubungula.

• I-Die Build-up: Ukunqwabelana kwe-polymer eyonakalisiwe noma izithasiselo endaweni ephumayo, okuholela emigqeni, amajeli, nokukhubazeka kwefilimu.

• I-Melt Fracture: Ukungahambi kahle endaweni yefilimu okubangelwa ukucindezelwa okuphezulu kwe-shear ku-die, okuholela ekubukekeni okumaholo noma okugagasi.

• Amajeli kanye Nama-Fisheyes: Izinhlayiya ze-polymer ezingahlakazekile noma ukungcola okuvela njengamaphutha amancane, asobala noma afiphele kufilimu.

Lezi zinselele ngokuvamile zenza kudingeke ukuthi kuncishiswe umugqa wokukhiqiza, ukwandisa udoti wezinto ezibonakalayo, futhi kudinga ukungenelela okuthe xaxa kwabasebenzisi, konke okunciphisa ukusebenza kahle kukonke. Ukusetshenziswa kwamasu kwezithasiselo, ikakhulukazi ama-ejenti ashelelayo kanye nama-anti-blocking, kudlala indima ebalulekile ekwehliseni lezi zinkinga nasekuthuthukiseni inqubo yokukhiqiza.

Izindlela Zokunqoba Izinselele Ekwenziweni Kwefilimu Yepulasitiki
