1.PE Incazelo Yefilimu Yokwelula
Ifilimu yokwelula ye-PE (eyaziwa nangokuthi i-stretch wrap) ifilimu yepulasitiki enezakhiwo zokuzinamathisela ezinganwetshwa futhi ziboshwe ngokuqinile ezimpahleni, kungaba ngakolunye uhlangothi (i-extrusion) noma izinhlangothi zombili (ezishaywayo).I-adhesive ayinamatheli ebusweni bempahla kodwa ihlala phezu kwefilimu.Akudingi ukuncipha kokushisa phakathi nenqubo yokupakisha, okusiza ukonga amandla, ukunciphisa izindleko zokupakisha, ukwenza lula ukuthutha kweziqukathi, nokuthuthukisa ukusebenza kahle kwezinto.Ukuhlanganiswa kwama-pallets nama-forklift kunciphisa izindleko zokuhamba, futhi ukukhanya okuphezulu kusiza ukuhlonza izimpahla, kunciphisa amaphutha okusabalalisa.
Imininingwane: Ububanzi befilimu yomshini 500mm, ububanzi befilimu obumanuwali 300mm, 350mm, 450mm, 500mm, ukujiya okungu-15um-50um, kungasikwa ngokucaciswa okuhlukahlukene.
2.Ukuhlukaniswa kwe-PE Stretch Film Use
(1)Ifilimu Yokwelula Mathupha:Le ndlela ikakhulukazi isebenzisa ukupakisha okwenziwa ngesandla, futhi ifilimu yokwelula ngesandla ngokuvamile inezidingo zekhwalithi ephansi.Umqulu ngamunye unesisindo esingama-4kg noma ama-5kg ukuze usebenze kalula.
(2)Ifilimu Yokunwetshwa Komshini:Ifilimu yokwelula umshini isetshenziselwa ukupakishwa kwemishini, ikakhulukazi eqhutshwa ukuhanjiswa kwezimpahla ukuze kuzuzwe ukupakishwa.Kudinga amandla aphezulu okushuba kanye nokunwebeka kwefilimu.
Isilinganiso esijwayelekile sokunwebeka singama-300%, kanti isisindo somqulu singama-15kg.
(3)Ifilimu Yokunwetshwa Ngaphambi Komshini:Lolu hlobo lwefilimu yokwelula lusetshenziselwa ikakhulukazi ukupakishwa kwemishini.Ngesikhathi sokupakisha, umshini wokupakisha uqala ukwelula ifilimu ngokwesilinganiso esithile bese uyisonga ngezimpahla ezizopakishwa.Incike ekunwebekeni kwefilimu ukuhlanganisa izimpahla.Umkhiqizo unamandla aqine kakhulu, ubude, nokumelana nokubhoboza.
(4)Ifilimu Enemibala:Amafilimu anwebekayo anombala atholakala ngombala oluhlaza okwesibhakabhaka, obomvu, ophuzi, oluhlaza okotshani, nomnyama.Abakhiqizi bawasebenzisela ukupakisha izimpahla ngenkathi behlukanisa phakathi kwemikhiqizo ehlukene, okwenza kube lula ukuhlonza izimpahla.
3.Ukulawulwa kwe-PE Stretch Film Adhesiveness
Ukunamathela okuhle kuqinisekisa ukuthi izingqimba zangaphandle zefilimu yokupakisha ziyanamathelana, zihlinzeka ngokuvikeleka kwendawo yemikhiqizo futhi zenze ungqimba olungaphandle oluyisivikelo olulula oluzungeze imikhiqizo.Lokhu kusiza ekuvimbeleni uthuli, uwoyela, umswakama, amanzi, kanye nokweba.Okubalulekile, ukwelula ukupakishwa kwefilimu kusabalalisa amandla ngokulinganayo ezintweni ezipakishiwe, ukuvimbela ingcindezi engalingani engabangela umonakalo emikhiqizweni, ongenakufezwa ngezindlela zokupakisha zendabuko ezifana nokubopha, ukuhlanganisa, kanye ne-tape.
Izindlela zokuzuza ukunamathela ngokuyinhloko zihlanganisa izinhlobo ezimbili: enye iwukwengeza i-PIB noma i-master batch yayo ku-polymer, kanti enye iwukuxuba ne-VLDPE.
(1) I-PIB iwuketshezi olungafihli lutho, olunama-viscous.Ukwengeza okuqondile kudinga okokusebenza okukhethekile noma ukuguqulwa kwezinto zokusebenza.Ngokuvamile, i-PIB masterbatch isetshenziswa.I-PIB inenqubo yokufuduka, evame ukuthatha izinsuku ezintathu, futhi iphinde ithintwe izinga lokushisa.Inokunamathela okuqinile emazingeni okushisa aphezulu kanye nokunamathela okuncane emazingeni okushisa aphansi.Ngemuva kokwelula, ukunamathela kwayo kuncipha kakhulu.Ngakho-ke, ifilimu eqediwe igcinwa kangcono phakathi kwebanga elithile lokushisa (ukushisa okunconywayo kwesitoreji: 15 ° C kuya ku-25 ° C).
(2) Ukuxuba ne-VLDPE kunokunamathela kancane kancane kodwa akudingi okokusebenza okukhethekile.Ukunamathela kuzinzile, akuhambisani nemingcele yesikhathi, kodwa futhi kuthinteka izinga lokushisa.Iyanamathela uma kuqhathaniswa namazinga okushisa angaphezu kuka-30°C futhi ayinamathele kancane emazingeni okushisa angaphansi kuka-15°C.Ukulungisa inani le-LLDPE kungqimba yokunamathisela kungafinyelela i-viscosity oyifunayo.Le ndlela ivame ukusetshenziselwa amafilimu e-co-extrusion enezingqimba ezintathu.
4.Izici ze-PE Stretch Film
(1)Ukuhlanganiswa: Lesi esinye sezici ezinkulu kakhulu zokupakishwa kwefilimu enwetshiwe, ebopha ngokuqinile imikhiqizo ibe yiyunithi ehlangene, engashintshi, ngisho nangaphansi kwezimo ezimbi, ukuvimbela noma yikuphi ukuxegiswa noma ukuhlukaniswa kwemikhiqizo.Iphakheji ayinayo imiphetho ebukhali noma ukunamathela, ngaleyo ndlela igwema ukulimala.
(2)Ukuvikela Okuyinhloko: Ukuvikela okuyisisekelo kunikeza ukuvikelwa kwangaphandle kwemikhiqizo, kudala ingaphandle elivikelayo elingasindi.Ivimbela uthuli, amafutha, umswakama, amanzi, nokweba.Ukupakishwa kwefilimu yokwelula kusabalalisa amandla ngokulinganayo ezintweni ezipakishiwe, kuvimbela ukufuduka nokunyakaza ngesikhathi sokuthutha, ikakhulukazi ezimbonini zikagwayi nezindwangu, lapho kunemiphumela eyingqayizivele yokupakisha.
(3) Ukonga Izindleko: Ukusebenzisa ifilimu enwetshiwe yokupakisha umkhiqizo kunganciphisa ngempumelelo izindleko zokusebenzisa.Ifilimu yokwelula idla cishe u-15% kuphela webhokisi lokuqala, cishe u-35% wefilimu enciphisa ukushisa, kanye namaphesenti angaba ngu-50 ephakethe lekhadibhodi.Iphinde yehlise izinga labasebenzi, ithuthukise ukusebenza kahle kokupakisha, futhi ithuthukise amamaki okupakisha.
Kafushane, inkambu yokusetshenziswa kwefilimu enwetshiwe ibanzi kakhulu, nezindawo eziningi eShayina ezisazohlolwa, futhi izindawo eziningi ezihloliwe azikasetshenziswa kabanzi.Njengoba insimu yesicelo ikhula, ukusetshenziswa kwefilimu enwetshiwe kuzokwanda kakhulu, futhi amandla ayo emakethe angenakulinganiswa.Ngakho-ke, kuyadingeka ukukhuthaza ngamandla ukukhiqizwa nokusetshenziswa kwefilimu elula.
5.Izicelo ze-PE Stretch Film
Ifilimu enwetshiwe ye-PE inamandla aqine kakhulu, ukumelana nezinyembezi, ukukhanya, kanye nezakhiwo ezinhle kakhulu zokululama.Ngesilinganiso sangaphambi kokwelula esingu-400%, singasetshenziselwa ukufaka iziqukathi, ukuvimbela amanzi, ukuvikela uthuli, ukunqanda ukuhlakazeka, kanye nezinjongo zokulwa nokweba.
Ukusetshenziswa: Isetshenziselwa ukugoqa i-pallet nokunye ukugoqa futhi isetshenziswa kakhulu ekuhwebeni kwamanye amazwe, ibhodlela kanye nokukhiqiza, ukwenza amaphepha, ihadiwe nezinto zikagesi, amapulasitiki, amakhemikhali, izinto zokwakha, imikhiqizo yezolimo, ukudla nezinye izimboni. .
