Amashidi okupakisha epulasitiki avame ukusetshenziswa ekwenziweni kwezinkomishi zepulasitiki ezilahlwayo, amapuleti, izitsha, amadiski, amabhokisi kanye neminye imikhiqizo efakwe ukushisa, futhi asetshenziswa kabanzi ekupakisheni ukudla, imifino, izithelo, iziphuzo, imikhiqizo yobisi, kanye nezingxenye zezimboni kanye nezingxenye. Ngokuguquguquka kwayo okuhle kakhulu kanye nokucaca okuphezulu, ishidi lokupakisha lepulasitiki lingabunjwa kalula libe yizitayela ezahlukahlukene zemfashini ukuze kuhlangatshezwane nezidingo ezahlukahlukene zemakethe. Uma kuqhathaniswa nemikhiqizo yengilazi, ishidi lokupakisha lepulasitiki limelana kakhulu nokuphuka, isisindo esincane, kulula ukulithutha nokuyigcina, kunciphisa kakhulu izindleko zezokuthutha.
Nokho,Imboni yokupakisha iqine kakhulu ezidingweni zokusebenza kweshidi lokupakisha lepulasitiki, kulindeleke ukuthi likwazi ukuba namandla omshini, ukumelana nokushisa, ukumelana nokubanda, isithiyo esisebenzayo kugesi namanzi, ukubukeka okucwebezelayo nokusobala, ukusebenza kahle kokuvala ukushisa, ukuzivumelanisa nezimo okuhle kakhulu kokuphrinta kanye nezakhiwo ezingezona ezinobuthi nezingenangozi. Ishidi lepulasitiki elinongqimba olulodwa, yize linezinzuzo ezithile, kodwa kusobala ukuthi alikwazi ukuhlangabezana ngokugcwele nalezi zidingo zokusebenza okuphezulu, ikakhulukazi ekupakisheni izinto ezizwela umoya-mpilo, ukusebenza kwalo kwesithiyo kuncane kakhulu kunezitsha zensimbi nengilazi.
Amashidi okuvimbela ahlanganisiwe anezingqimba eziningi akhona ukuze ahlale
Ngakho-ke,ukuze kuhlangatshezwane nesidingo semboni yokupakisha sezinto zokupakisha zepulasitiki ezisebenza kahle kakhulu, kwazalwa ishidi lokuvimbela elihlanganisiwe elinezingqimba eziningiNgokukhipha ngobuhlakani izinhlobo ezahlukene zezinto zokusetshenziswa zepulasitiki ukuze kuhlanganiswe izinto eziningi, unganikeza izici ezihlukile zezinto ngayinye, izinzuzo zezinhlobo ezahlukene zama-resin zibe yinto eyodwa, ukuze uthuthukise ngokuphelele ukusebenza okuphelele kwemikhiqizo yokupakisha. Leli shidi lezinto eziningi aligcini nje ngokubaizakhiwo ezinhle kakhulu zokuvimbela, ingavikela ngempumelelo izimpahla endaweni engaphandle, kodwa futhi ineamandla amahle kakhulu omshini kanye nokumelana nokushisa nokubanda, ukuqinisekisa ukuthi imikhiqizo yokupakisha ezindaweni ezahlukahlukene ezinzima ingagcina ukusebenza okuzinzile. Ngesikhathi esifanayo,ukunyathelisa okuhle nokuzivumelanisa nezimo kanye nezakhiwo ezingezona ezinobuthi nezingenangozifuthi kwenzeiba yinto ethandwayo ezindaweni eziningi zokupakisha.
Uhla olubanzi lwezicelo zamashidi ezithiyo ezihlanganisiwe ezisebenzisa izingqimba eziningi
Amashidi okuvimbela ahlanganisiwe anezingqimba eziningi asetshenziswa ezinhlobonhlobo zezicelo ezihlanganisa ukudla, imithi, imikhiqizo kagesi, izidingo zansuku zonke, izimonyo kanye neminye imikhakha eminingi.
Ephaketheni lokudla, ingasetshenziswa ukuvikela ukudla okonakalayo njengezithelo nemifino emisha, inyama, imikhiqizo yobisi, njll. nokwandisa isikhathi sazo sokuphila;
Emaphaketheni emithi, kuvimbela izidakamizwa ukuthi zingabi namandla ngenxa yomswakama, ukushiswa noma ukuchayeka ekukhanyeni;
Ephaketheni lezimonyo, kungavimbela ngempumelelo ukuhlasela kwamagciwane futhi kuhlinzeke ngendawo yokupakisha engcolile. Thuthukisa ubuhle bephakheji futhi kwandise ukusebenza kwayo, njengokulula ukuyiphatha nokulula ukuyivula.
Umugqa Wokunwetshwa Kweshidi Lomgoqo We-PP/PE/PA/PETG/EVOH
Embonini yesimanje yokupakisha, ukukhethwa kwezinto kanye nokusungula izinto ezintsha kuyizinto ezibalulekile embonini. Njengoba abathengi bekhathazeka kakhulu ngokuphepha, isikhathi sokuphelelwa yisikhathi kanye nokusebenza kwemvelo kwezimpahla zabo,ukusebenza kanye nokusimama kwezinto zokupakishaziphakathi nendawo yokunaka kwemakethe. Ngenxa yalesi simo, amashidi okuvimba ahlanganisiwe anezingqimba eziningi avele ngokushesha njengezintandokazi ezintsha emkhakheni wokupakisha ngenxa yezinzuzo zawo zokusebenza ezihlukile.
Umugqa Wokunwetshwa Kweshidi Lokuvinjelwa Kwezingqimba Eziningi ze-PP/PE/PA/PETG/EVOH ovela ku-JWELLishidi elihlelwe ngezingqimba eziningi elakhiwe ngokukhishwa ngasikhathi sinye kwezinto zokusetshenziswa zepulasitiki ezinezakhiwo ezahlukene ngokulandelana okuthile kanye nesilinganiso. Lobu buchwepheshe buvumela ukulawula okunembile kobukhulu kanye nokwakheka kwesendlalelo ngasinye ukuze kufezwe inhlanganisela engcono kakhulu yezakhiwo. Ngobuchwepheshe be-multilayer co-extrusion, izinto zokusetshenziswa ezifana ne-PP, PE, PA, PETG kanye ne-EVOH zingahlanganiswa ngobuchule ukuzeyakha amashidi okuvimba ahlanganisiwe anezingqimba eziningi anezakhiwo ezinhle kakhulu zokuvimba, izakhiwo zemishini kanye nokubukeka.Isendlalelo ngasinye sithatha umsebenzi othize, njengokuvimba amagesi, umhwamuko wamanzi, ukukhanya, njll., noma ukunikeza amandla okusebenza, ukumelana nokushisa nokubanda. Ngokuklama kahle isakhiwo nezinto zesendlalelo ngasinye, kungenzeka ukufeza izinga eliphezulu lokwenza ngokwezifiso ukusebenza kokupakisha ukuze kuhlangatshezwane nezidingo zokupakisha zezimpahla eziningi ezahlukene.
Isicelo:Izinto ze-EVOH zinezakhiwo ezinhle zokuvimba. Ngobuchwepheshe bokunweba ngokubambisana ne-PP, PE, PA, PETG nezinye izinto, zingacutshungulwa zibe izinto zokupakisha ezilula ezinezingqimba ezi-5, ezinezingqimba ezi-7, kanye nezingqimba ezi-9, ezisetshenziswa kakhulu ekupakisheni okungenamagciwane, iziphuzo zejeli, imikhiqizo yobisi, ukupakisha kwezinhlanzi ezibandayo kanye nemikhiqizo yenyama njll. Esimweni esingeyona ukudla, isetshenziswa ekupakisheni kwemithi, okushintshashintshayo kwe-solvent nakwezinye izinkambu, ngezakhiwo ezinhle kakhulu zokuvimba, okuthuthukisa kakhulu impilo yeshelufu yemikhiqizo.
Ipharamitha yobuchwepheshe eyinhloko:
Qaphela:Ulwazi olubalwe ngenhla lungolwesithenjwa kuphela, umugqa wokukhiqiza ungakwenzakuklanywe ngokwezidingo zamakhasimende.
Njengokusungula izinto ezintsha embonini yokupakisha, ishidi lokuvimbela elihlanganisiwe elinezingqimba eziningi aligcini nje ngokuthuthukisa ukusebenza kanye nokwehlukahluka kwezinto zokupakisha, kodwa futhi linikeza abathengi izixazululo zokupakisha eziphephile, ezilula futhi ezinobungani nemvelo.Esikhathini esizayo, ngentuthuko eqhubekayo yobuchwepheshe kanye nokwanda kwemakethe, amathuba okusetshenziswa kweshidi lokuvimbela elihlanganisiwe elinezingqimba eziningi azoba maningi.
