ipallet yolula ifilimu yokupakisha

Ifilimu eyolulayo, ekwabizwa ngokuba yifilim eyolulayo kunye nefilimu yokuncipha kobushushu, yeyokuqala eTshayina ukuvelisa ifilimu eyoluliweyo yePVC enePVC njengesiseko semathiriyeli kunye ne-DOA njengeplastiki kunye nesiphumo sokuzincamathela. Ngenxa yemiba yokhuseleko lokusingqongileyo, ixabiso eliphezulu (ngokunxulumene nomlinganiselo ophezulu wePE, indawo yokupakisha engaphantsi kweyunithi), ukungakwazi ukunwebeka, njalo njalo, yapheliswa kancinane xa kwaqaliswa ukuveliswa kwefilimu yasekhaya yePE ukusuka ku-1994 ukuya ku-1995. I-PE ifilimu eyolulayo kuqala isebenzisa i-EVA njengezinto zokuzibamba, kodwa ixabiso layo liphezulu kwaye linokunambitheka. Kamva, i-PIB kunye ne-VLDPE zisetyenziswa njengezinto zokuzincamathela ngokwazo, kwaye isiseko semathiriyeli yi-LLDPE. Ifilimu eyolulayo inokwahlulwa ibe: ifilimu ye-PE, ifilimu ye-PE, ifilimu eyolulayo ye-LLDPE, ifilimu ye-PE slit stretch, njl. Inokuvelisa ifilimu eyoluliweyo esebenzayo yokusetyenziswa kwezandla, ukusetyenziswa komatshini wohlobo lokumelana, ukusetyenziswa komatshini wohlobo lwangaphambili, i-anti-ultraviolet, i-anti-static kunye ne-anti-rust. Inezi zinzuzo zilandelayo: Ukusebenzisa izixhobo eziphindwe kabini ze-co-extrusion, ifilimu eyolulayo ecinezelekileyo inokwandisa iimpawu zepolymer nganye, kunye nokucaca kwayo, amandla okuqina, kunye nokuchasana kwe-perforation yeyona nto ingcono xa ifikelela kwindawo yokunyibilika. ubume. 2. Inokwazi ukolula okulungileyo, ukucaca kakuhle kunye nobukhulu obufanayo. 3. Inokwandiswa kwe-longitudinal, ukomelela okulungileyo, ukuxhathisa okulungileyo okunqamlezayo kokukrazula, kunye ne-self-adhesive lap. 4. Yimathiriyeli ehambelana nokusingqongileyo kwaye inokuphinda isetyenziswe, ayinancasa, ayinatyhefu, kwaye inokupakisha ukutya ngokuthe ngqo. 5. Iyakwazi ukuvelisa iimveliso ze-viscous ezinecala elinye, ukunciphisa ingxolo ekhutshwe ngexesha lokuhamba kunye nokwelula, kunye nokunciphisa uthuli kunye nesanti ngexesha lokuthutha kunye nokugcinwa. 1. Ukupakishwa okutywiniweyo Olu hlobo lokupakisha lufana nokunciphisa ifilimu yokupakisha. Ifilimu isonga i-tray malunga ne-tray, kwaye emva koko ii-thermal grippers ezishushu zitywina ifilimu kuzo zombini iziphelo. Le yindlela yokuqala yokusetyenziswa kwefilimu eyolulayo, kwaye iifom zokupakisha ezininzi ziye zaphuhliswa ukusuka kule 2. Ukupakishwa kobubanzi obugcweleyo Olu hlobo lokupakisha lufuna ukuba ifilimu ibe banzi ngokwaneleyo ukugubungela i-pallet, kwaye imilo yephalethi iqhelekile, ngoko ke. ineyayo, ilungele ukutyeba kwefilimu eyi-17～35μm 3. Ukupakishwa ngesandla Olu hlobo lokupakisha lolona hlobo lulula lokupakishwa kwefilim. Ifilimu ifakwe kwi-rack okanye ibanjwe ngesandla, kwaye i-tray ijikeleza okanye ifilimu ijikeleze i-tray. Ikakhulu isetyenziselwa ukupakishwa kwakhona emva kokuba i-pallet esongiwe yonakele, kunye nokupakishwa kwepalethi eqhelekileyo. Olu hlobo lwesantya sokupakisha lucotha, kwaye ubukhulu befilimu obufanelekileyo bu-15-20μm; 4. Ifilimu eyoluliweyo yokupakisha umatshini wokugoqa Le yeyona ndlela ixhaphakileyo kwaye ibanzi yokupakisha ngoomatshini. I-tray iyajikeleza okanye ifilimu ijikeleza i-tray. Ifilimu igxininiswe kwisibiyeli kwaye iyakwazi ukunyuka naphantsi. Olu hlobo lomthamo wokupakisha lukhulu kakhulu, malunga neetreyi ezili-15-18 ngeyure. Ubunzima befilimu obufanelekileyo bu malunga ne-15-25μm; 5. I-Horizontal mechanical packaging Ihluke kwezinye iipakethe, ifilimu ijikeleza kwimpahla, ilungele ukupakishwa kwempahla ende, efana neekhaphethi, iibhodi, ii-fiberboards, izinto ezibunjiweyo, njl.; 6. Ukupakishwa kweetyhubhu zephepha Le ngenye yezinto ezisandul 'ukusetyenziswa kwefilimu eyolulayo, engcono kuneepakethe zetyhubhu zephepha zakudala. Ubukhulu befilimu obufanelekileyo yi-30～120μm; 7. Ukupakishwa kwezinto ezincinci Le yindlela yokupakisha yamva nje yefilimu eyolulayo, engakwazi ukunciphisa kuphela ukusetyenziswa kwezinto eziphathekayo, kodwa nokunciphisa indawo yokugcina iipallets. Kwamazwe angaphandle, olu hlobo lokupakisha lwaqala ukuqaliswa ngo-1984. Emva konyaka omnye kuphela, ezininzi iipakethe ezinjalo zavela kwimarike. Le fomu yokupakisha inamandla amakhulu. Ilungele ubukhulu befilimu ye-15～30μm; 8. Ukupakishwa kweetyhubhu kunye neentambo Lo ngumzekelo wokusetyenziswa kwefilimu eyolulayo kwintsimi ekhethekileyo. Izixhobo zokupakisha zifakwe ekupheleni komgca wemveliso. Ifilimu yokwelula ngokuzenzekelayo ayinakuthatha indawo kuphela i-tape ukuze ibophe izinto eziphathekayo, kodwa iphinde idlale indima yokukhusela. Ubunzima obusebenzayo bu-15-30μm. 9. Indlela yokolula yendlela yokupakishwa kwepalethi Ukupakishwa kwefilimu eyoluliweyo kufuneka yolulwe. Iifom zokwelula ze-pallet mechanical packaging ziquka ukunweba ngokuthe ngqo kunye nokwelula kwangaphambili. Ukolula kwangaphambili kwahlulwe kwiintlobo ezimbini, enye i-roll pre-stretching kwaye enye i-electric stretching. Ukolula ngokuthe ngqo kukugqiba ukolula phakathi kwetreyi kunye nefilimu. Umlinganiselo wokwelula le ndlela uphantsi (malunga ne-15% -20%). Ukuba umlinganiselo wokwelula udlula i-55%～60%, edlula indawo yesivuno sokuqala sefilimu, ububanzi befilimu buyancipha, kwaye ukusebenza kwe-puncture kulahlekile. Kulula ukuqhekeza. Kwaye kwi-60% yereyithi yokwelula, amandla okutsala asekhulu kakhulu, kwiimpahla ezilula, kunokwenzeka ukuba zikhubaze iimpahla.
