ESULA IFIlimi

Ifilimu yokwelula, ebizwa nangokuthi ifilimu enwetshiwe kanye nefilimu yokunciphisa ukushisa, iyifilimu yokuqala yasekhaya enwetshiwe ye-PVC ukukhiqizwa nge-PVC njengento eyisisekelo kanye ne-DOA njengepulasitiki nokuzinamathisela.Ngenxa yezinkinga zokuvikelwa kwemvelo, izindleko eziphezulu (ezihlobene nenani eliphezulu le-PE, indawo encane yokupakisha iyunithi), ukunwebeka okungekuhle, njll., kancane kancane yaqedwa lapho kuqaliswa ukukhiqizwa kwasekhaya kwefilimu ye-PE stretch kusukela ngo-1994 kuya ku-1995. Ifilimu ye-PE stretch film iqale yasebenzisa i-EVA njengezinto ezizinamathelayo, kodwa izindleko zayo zaziphezulu futhi inokunambitheka.Kamuva, i-PIB ne-VLDPE yasetshenziswa njengezinto zokuzinamathela, futhi izinto eziyisisekelo zaziyi-LLDPE, okuhlanganisa i-C4, i-C6, i-C8 ne-metallocene PE (MPE).

Sebenzisa ifomu:

1. Amaphakheji avaliwe

Lolu hlobo lokupakisha lufana ne-shrink film package.Ifilimu isonga ithreyi ethreyini, bese kuba izibambo ezimbili ezishisayo zivala ifilimu kuzo zombili iziphetho.Lolu uhlobo lokuqala lokusebenzisa ifilimu enwetshiwe, futhi amafomu amaningi okupakisha enziwe kusukela kulokhu

2. Ukupakishwa kobubanzi obugcwele

Lolu hlobo lokupakisha ludinga ukuthi ifilimu ibe banzi ngokwanele ukumboza i-pallet, futhi ukuma kwephalethi kujwayelekile, ngakho-ke inokwayo, ilungele ukushuba kwefilimu okungu-17～35μm.

3. Ukupakisha okwenziwa ngesandla

Lolu hlobo lokupakisha luwuhlobo olulula kakhulu lokupakishwa kwefilimu elula.Ifilimu ifakwe ku-rack noma ibanjwe ngesandla, ijikeleziswa ngethreyi noma ifilimu izungeza ithreyi.Isetshenziselwa ikakhulukazi ukupakishwa kabusha ngemuva kokulimala kwe-pallet eboshwe, kanye nokupakishwa kwe-pallet evamile.Lolu hlobo lwejubane lokupakisha luhamba kancane, futhi ubukhulu befilimu obufanele bungama-15-20μm;

4. Yelula ifilimu ukusonga umshini emaphaketheni

Lolu uhlobo oluvame kakhulu futhi olubanzi lokupakisha ngomshini.Ithreyi liyazungeza noma ifilimu izungeza ithreyi.Ifilimu igxilwe kubakaki futhi ingakwazi ukuhamba phezulu naphansi.Lolu hlobo lomthamo wokupakisha lukhulu kakhulu, cishe amathreyi ayi-15-18 ngehora.Ubukhulu befilimu obufanele bungaba ngu-15～25μm;

5. Ukupakishwa kwemishini evundlile

Ihluke kwamanye amaphakheji, ifilimu izungeza isihloko, esifanele ukupakishwa kwezimpahla ezinde, njengamakhaphethi, amabhodi, ama-fiberboards, izinto ezimise okukhethekile, njll.;

6. Ukupakishwa kwamashubhu ephepha

Lokhu kungenye yezinto zakamuva ezisetshenziswayo zefilimu enwetshiwe, engcono kunepaki yakudala yamashubhu ephepha.Ubukhulu befilimu obufanele bungama-30～120μm;

7. Ukupakisha izinto ezincane

Lona uhlobo lwakamuva lokupakisha lwefilimu elula, elingakwazi ukunciphisa ukusetshenziswa kwezinto ezibonakalayo kuphela, kodwa futhi linciphise indawo yokugcina ama-pallets.Emazweni angaphandle, lolu hlobo lokupakisha lwaqala ukwethulwa ngo-1984. Ngemva konyaka owodwa, amaphakheji amaningi anjalo avela emakethe.Leli fomu lokupakisha linamandla amakhulu.Ifanele ukushuba kwefilimu okungu-15～30μm;

8. Ukupakishwa kwamashubhu nezintambo

Lesi isibonelo sokusetshenziswa kwefilimu yokwelula emkhakheni okhethekile.Impahla yokupakisha ifakwe ekupheleni komugqa wokukhiqiza.Ifilimu yokwelula ezenzakalelayo ngokugcwele ayikwazi ukufaka esikhundleni se-tape kuphela ukuze ibophe izinto ezibonakalayo, kodwa futhi idlale indima yokuzivikela.Ugqinsi olusebenzayo luyi-15-30μm.

9. Indlela yokwelula yokupakishwa kwendlela ye-pallet

Ukupakishwa kwefilimu enwetshiwe kufanele kunwetshwe, futhi izinhlobo ezinwebekayo zokupakishwa kwemishini ye-pallet zihlanganisa ukwelula okuqondile kanye nokwelula kwangaphambili.Kunezinhlobo ezimbili ze-pre-stretching, enye i-roll pre-stretching kanti enye i-electric stretching.
