Amashidi okupakisha epulasitiki avame ukusetshenziswa ekwenzeni izinkomishi zepulasitiki ezilahlwayo, amapuleti, izitsha, ama-disc, amabhokisi neminye imikhiqizo ye-thermoformed, futhi asetshenziswa kabanzi ekupakishweni kokudla, imifino, izithelo, iziphuzo, imikhiqizo yobisi, nezingxenye zezimboni kanye nezingxenye. . Ngokuguquguquka kwayo okuhle kakhulu nokucaca okuphezulu, ishidi lokupakisha lepulasitiki lingabunjwa kalula libe yizitayela ezahlukahlukene zemfashini ukuhlangabezana nezidingo ezihlukene zemakethe. Uma kuqhathaniswa nemikhiqizo yengilazi, ishidi lokupakisha lepulasitiki limelana kakhulu nokuqhekeka, isisindo esilula, ukuthuthwa kalula nokugcinwa, kunciphisa kakhulu izindleko ze-logistics.
Nokho,imboni yokupakisha iqine kakhulu ezidingweni zokusebenza kweshidi lokupakisha lepulasitiki, kulindeleke ukuthi ikwazi ukuba namandla emishini, ukumelana nokushisa, ukumelana nokubanda, umgoqo osebenzayo wegesi nomhwamuko wamanzi, ukubukeka okucwebezelayo nokusobala, ukusebenza kahle kokuvalwa kokushisa, ukuvumelana nezimo zokuphrinta okuhle kakhulu kanye nezakhiwo ezingenabuthi nezingenabungozi. Ishidi lepulasitiki elinongqimba olulodwa, nakuba linezinzuzo ezithile, kodwa ngokusobala alikwazi ukuhlangabezana ngokugcwele nalezi zidingo ezisebenza kahle kakhulu, ikakhulukazi emaphaketheni ezimpahla ezizwela umoya-mpilo, ukusebenza kwalo kwesithiyo kuncane kakhulu kuneziqukathi zensimbi nezengilazi.
Amashidi okuvimbela ama-multilayer co-extruded alapha ukuze ahlale
Ngakho-ke,ukuze kuhlangatshezwane nesidingo semboni yokupakisha sezinto zokupakisha zepulasitiki ezisebenza kahle, kwazalwa ishidi lokuvimbela i-multilayer co-extruded. Ngokukhipha ngobuhlakani izinhlobo ezahlukahlukene zezinto zokusetshenziswa zepulasitiki zenhlanganisela yezendlalelo eziningi, unganikeza ukudlala okugcwele kuzakhiwo ezihlukile zento ngayinye, izinzuzo zezinhlobonhlobo zama-resin zibe yinto eyodwa, ukuze kuthuthukiswe ngokuphelele ukusebenza okuphelele kokupakisha. imikhiqizo. Leli shidi eliyinhlanganisela yezendlalelo eziningi aligcini nje ngokuba naloizindawo ezinhle kakhulu zokuvimbela, ingavikela ngempumelelo impahla endaweni yangaphandle, kodwa futhi ineamandla amahle kakhulu emishini nokushisa nokumelana nokubandayo, ukuqinisekisa ukuthi imikhiqizo yokupakisha ezindaweni ezihlukahlukene ezinokhahlo ingagcina ukusebenza okuzinzile. Ngesikhathi esifanayo, yayoukuguquguquka okuhle kokuphrinta kanye nezakhiwo ezingenabuthi nezingenabungozifuthi yenzeibe yinto ekhethwayo ezindaweni eziningi zokupakisha.
Ibanga elibanzi lezinhlelo zokusebenza zamashidi okuvimbela ama-multilayer co-extruded
Amashidi okuvimbela ama-multi-layer co-extruded asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa ukudla, imithi, imikhiqizo ye-elekthronikhi, izidingo zansuku zonke, izimonyo neminye imikhakha eminingi.
Emaphaketheni okudla, ingasetshenziselwa ukuvikela ukudla okonakalayo njengezithelo nemifino emisha, inyama, imikhiqizo yobisi, njll. futhi andise impilo yakho yeshalofu;
Emaphaketheni emithi, kuvimbela izidakamizwa ukuba zingasebenzi ngenxa yomswakama, i-oxidation noma ukuchayeka ekukhanyeni;
Emaphaketheni ezimonyo, ingavimbela ngempumelelo ukuhlasela kwama-microorganisms futhi inikeze indawo yokupakisha eyinyumba. Thuthukisa ubuhle bephakheji futhi wandise ukusebenza kwayo, njengokulula ukukuthwala nokuvuleleka kalula.
PP/PE/PA/PETG/EVOH Multilayer Barrier Sheet Co-extrusion Line
Embonini yesimanje yokupakisha, ukukhethwa kwempahla kanye nokuqanjwa kabusha kuyizici ezibalulekile embonini. Njengoba abathengi bekhathazeka kakhulu ngokuphepha, impilo yeshalofu nokusebenza kwemvelo kwezimpahla zabo,ukusebenza kanye nokusimama kwezinto zokupakishaziphakathi nendawo emakethe. Ngokumelene nalokhu kwangemuva, amashidi okuvimbela ama-multilayer co-extruded avela ngokushesha njengentandokazi entsha emkhakheni wokupakisha ngenxa yezinzuzo zawo zokusebenza ezihlukile.
I-PP/PE/PA/PETG/EVOH I-Multilayer Barrier Sheet Co-extrusion Line esuka ku-JWELLiyishidi elakhiwe ngezingqimba eziningi elakhiwe ngokukhipha kanyekanye kwezinto zokusetshenziswa zepulasitiki ezinezakhiwo ezihlukene ngendlela ethile nesilinganiso. Lobu buchwepheshe buvumela ukulawula okunembile kogqinsi nokwakheka kwesendlalelo ngasinye ukuze kuzuzwe inhlanganisela engcono kakhulu yezakhiwo. Ngobuchwepheshe be-multilayer co-extrusion, izinto ezingavuthiwe ezifana ne-PP, PE, PA, PETG ne-EVOH zingahlanganiswa ngobuhlakani ukuzeyakha amashidi okuvimbela ama-multilayer co-extruded anezakhiwo ezinhle kakhulu zokuthibela, izakhiwo zemishini nokubukeka.Isendlalelo ngasinye sithatha umsebenzi othile, njengamagesi okuvimbela, umhwamuko wamanzi, ukukhanya, njll., noma ukunikeza amandla emishini, ukumelana nokushisa nokubanda. Ngokuklama ngokunembile isakhiwo kanye nokokusebenza kwesendlalelo ngasinye, kungenzeka ukufeza izinga eliphezulu lokwenza ngokwezifiso ukusebenza kokupakisha ukuze kuhlangatshezwane nezidingo zokupakisha zezinhlobonhlobo zezimpahla.
Isicelo:Impahla ye-EVOH inezinto ezinhle zokuvimbela. Ngobuchwepheshe be-co-extrusion nge-PP, PE, PA, PETG nezinye izinto, ingacutshungulwa ibe yi-5-layer, 7-layer, kanye ne-9-layer high-barrier lightweight lightweight, esetshenziswa kakhulu emaphaketheni aseptic, iziphuzo ze-jelly , imikhiqizo yobisi, inhlanzi ebandayo kanye nemikhiqizo yenyama ukupakishwa njll. Esicini okungezona ukudla, isetshenziswa kwezemithi, i-solvent eguquguqukayo. ukupakisha nezinye izinkambu, ezinezakhiwo ezinhle kakhulu zokuvimbela, ezithuthukisa kakhulu impilo yeshalofu yemikhiqizo.
Ipharamitha yobuchwepheshe eyinhloko:
Qaphela:Imininingwane ebalwe ngenhla ingeyereferensi kuphela, ulayini wokukhiqiza ungawenzaiklanywe ngokwezidingo zekhasimende.
Njengokuqanjwa okusha okubalulekile embonini yokupakisha, ishidi lokuvimbela i-multilayer co-extruded aligcini nje ngokukhuthaza ukuthuthukiswa kokusebenza kanye nokwehlukahlukana kwezinto zokupakisha, kodwa futhi linikeza abathengi izixazululo zokupakisha eziphephile, ezilula kakhulu nezivumelana nemvelo.Ngokuzayo, ngenqubekelaphambili eqhubekayo yobuchwepheshe nokunwetshwa kwemakethe, ithemba lokusetshenziswa kweshidi lokuvimbela i-multilayer co-extruded lizoba banzi.
