Ukukhetha i-Plastic Roll Film Esebenzayo Kulemnyango

Ukufakanya i-Specification Yefilm Ngokulingana Nezidingo Zokusebenza

Ukukhetha okufanele ifilimu yokuqala esihlwini iqala ngokwazi kahle kokuthi ifilimu kufanele yenzela nini ngalunye luhlakani lweprosesi yokupakisha nokuthumela. Abathengi kufanele bakhombise iprofile yokulayisha (umbhane, imizilingo, ukungafaneleli ukubhekana nomthwalo), umdlalo wokusebenzisa (izimo zokuchitha, ukuchitha kwamaphuzu, ukubhekana nezinkimanga), izinkampani zokusebenza ezisebenzayo, futhi noma yiliphi imithwalo yezomnotho ephakathi kwezinto ezizokuthunyelwa. Njengoba lezi zindaba ziyisikhwama, uprosesi lokukhetha kusuka kuzo kuyisibonelo sokuhambisana esihle kunezinye izindlela zokuthenga okungasemthwalo.

Ukubala (ukubhala) kuyisibonelo esisodwa kakhulu xa kufundiswa ukulandela ukuphatha phakathi kwezidingo zokulinda nokuthenga kwemithombo, kodwa akufanele kubhekelwa njengesibonelo esisodwa kuphela. Isifilm esincane ngokubhala noma kunjalo, uma isifunda sokubhala sasemthwakweni sivumelana ngokuphelele, singaqhubeka ngokuphelele kune-sifilm esikhulu kakhulu esenziwa ngomthwakweli wokubhala ongavumelekile kakhulu emisebenzini yayo yezinhloso zokuphatha nokuthenga ngalunye isilinganiso sokulinda. Lokhu kukuthi ukubheka isifilm seplastik sokugcina ngokuthenga ngalunye ipallet noma ngalunye isilinganiso sokugcina — kungafanele ukubheka kuphela ngokuthenga ngalunye ikilogramu — kusinika isibonelo esihle kakhulu sesivumelano sesikhona.

Izinkinga Zokuphatha Ngokuphelele Kukuthenga Kwesifilm Seplastik

Ukuphatha ngokuphelele kusenziwa isibonelo esikhulu kule- ifilimu yokuqala esihlwini iziphakamiso zokuthenga kwezindawo zokudla nokusebenza. Abathengi bafuna ngokuphelele amafilmi okuthi abe nezinto ezisuselwe kwezinye izinto ezenziwe kabusha (ezisuselwe kubantu noma kwezindawo zokusebenza), ziyasebenza ngokuhambisana nezindlela zokuzenzela kabusha, noma zinika ukwenzela kahle ukugcina kwezifilmi okukhula ukugcina kwemitha yezibonelo sokuthenga. Lezi zimfundo zihambisana nezimfundo zokuxhumana kwezindawo zokusebenza, izimfundo zabantu abathengi, nokuthi izimfundo zokulungisa izinto ziyagcina kwezindawo ezingaphezulu.

Ukugcina kwezifilmi — ukugcina ubude bezifilmi ngaphandle kokugcina ukusebenza — yindlela eyinkulu yokuxhumana kwezindawo zokusebenza kubantu abathengi abasebenza ngazo ifilimu yokuqala esihlwini . Intuthuko kwezobuchwepheshe be-LLDPE ne-metalocene PE resin yenze kwaba nokwenzeka ukufeza ukusebenza okufanayo noma okungcono kwemishini nge-gauge encishisiwe kakhulu uma kuqhathaniswa namafilimu akhiqizwa eminyakeni eyishumi edlule.

Ukuze kusetshenziswe ukudla, izakhiwo zezinto eziyodwa lapho zonke izingqimba zezinto eziphilayo zikhona ifilimu yokuqala esihlwini zenziwe ngomndeni owodwa we-polymer zithola ukuthandwa ngoba zenziwa kalula ngokuvuselelwa kwemishini kunama-laminate amaningi ahlanganisa izinhlobo ezahlukene ze-polymer. Nakuba kungezona zonke izinhlelo zokusebenza ezingase zisetshenziswe ifilimu ye-mono-material, isigaba semikhiqizo lapho lokhu kungatholakala khona sikhula njengoba isayensi yezinto ezithuthukayo, okwenza kube kuhle ukuhlola ngesikhathi sokuthuthukiswa komkhiqizo ngamunye noma umjikelezo wokwakha kabusha.

Imibuzo Evame Ukubuzwa

Uyini umehluko phakathi kwefilimu yokwelula nefilimu yokucinana ekusetshenzisweni kwefilimu yepulasitiki?

Isifilm sokugcina sisebenzisa ngokupheleka kwezindawo zokugcina futhi sibonakalisa ukuthi isifilm sokugcina sisebenzisa umsebenzi wokubuyela kwakho kweplastiki — akukho thepelo esebenziswa. Isifilm sokugcina ngokupheleka sisebenzisa ngokungafani kanye ngezinto ezithile, emva kwalokho kusondwa ngaphansi kwesikhathi sokupheleka, lapho kufana ngokupheleka kwezinto ezingathathwa. Umunye umkhulu wezifilm ziyasebenza ngokwesibonelo: isifilm sokugcina sisebenzisa kakhulu ekugcineni amapalleti futhi ekugcineni izinto ezihlukene, ngakho-ke isifilm sokugcina ngokupheleka sisebenzisa kakhulu ekugcineni izinto zokuthengiselwa, ukuthi kubonakale ukuthi akukho mthetho wokugcina, nokugcina izinto zokuthengiselwa.

Isifilm sokugcina seplastiki singaba yini ubude bakho bokugcina kwezinto zokusebenza ngokupheleka?

Kusukela kwezinkampani zokubhala izipalathe ngokuzenzakalelayo, umfanekiso wokubhala okuphelele kwezinto ezinamathuba amaningi, nokuthi ukubhala kwenziwa ngokusebenzisa isistimu sokubhala ngokuvutha kabefore, umfanekiso wokubhala weplastiki kumakhulu ama-20 kuze kuma-23 mikroni yisikrini esifanele. Izilwanyana ezenzeka kakhulu, izimo ezingafanele, noma izilwanyana ezenza izihlangothi ezibomvu ziyabizwa ukubhala ngokuphelele kwezikhulu ama-25 kuze kuma-30 mikroni, noma ukubhala ngokuphelele kwezinhlobo eziphelele zokuvikela kakhulu kwezihlangothi. Isikrini esifanele sibuyiselwe ngokuzimisela ngokuzimisela kwesilwanyana phakathi kwezimo zokugcina izilwanyana zokubhala izipalathe zokuhamba noma kusakwa.

Ingaba umfanekiso wokubhala weplastiki ungasetyenziswa ekubheleni kwezinto zokudla ngqo?

Yebo, ukuba ifilm ye-plastic roll esithile isebenzisa ngokufanekayo futhi isivumelwe ukusebenza ngezinto zokudla ngokuhambisana nezindlela zokulawula eziphathelene nesifundo sokuziphatha kwenqubo yezindawo ezizocashwa. Amafilimu okudla kufanele abeze resin ephathelene nokuvumelwa kanye nezinkampani ezivumelwe, futhi umthengisi kufanele abeke ukuthi kubonakala ukuthi kuyavumelwa ngokuphelele noma ukuthi kunezincwadi zokuvumela ukuthi kuyavumelwa ngokuphelele. Akukho konke amaproduct ase-plastic roll asebenzayo kusenqubomgomo kuyasebenza ngokugcina izinto zokudla ngokugcina, ngoko ke kubalulekile ukubona ukuthi kuyavumelwa ngokuphelele kabusha ngaphambi kokusebenzisa ifilm njengoba iyasebenza ngokugcina izinto zokudla.

Izifaktor ziphi ezingabangela ukuthi ifilm ye-plastic roll ibe yinkulungwane yokuthenga ngokuphelele kwenqubo yokuqasha kwezinkampani?

Izinkomba ezingamandla kakhulu ezikuthintana nokusebenza kwezindleko zokusebenzisa i-plastic roll film ngokubanzi ziyizindleko zemithambo yefilm, isilinganiso sesikhala (kukhethwa kwezindleko zokusikhala), ukulinganiswa kwefilm (imithambo yefilm ngamakilogramu), ukufaneleka kwezinhlelo zokusebenza, nokuphakanyeka kwesikhathi sokuvaleka kwefilm noma ukungasebenzi kwezinhlelo. I-plastic roll film eyingaphezulu kahle kwezindleko engaphansi kwezindleko, kodwa iyasebenza ngempela ngokuphelele kwezikhala ezingaphezulu, ibe yincinane kwezivalelo, futhi ibonisa ukulinganiswa okuphelele ngamakilogramu, kuyabonisa ukuthi kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphelele kwezindleko zokusebenzisa konke kuloko kuyasebenza ngokuphele......
