Okwangoku, ukupakishwa kokufutha kunye nokubulala iintsholongwane kwahlulwe kakhulu kwiindidi ezimbini: izakhiwo zeplastiki kunye ne-aluminium-plastiki. Ngokweemfuno ze-GB/T10004-2008, iimeko zokupheka zahlulwe zibe ngamanqanaba amabini: ukupheka ngobushushu obuphantsi (ngaphezulu kwe-100 ° C ukuya kwi-121 ° C) kunye nokupheka ngobushushu obuphezulu (ngaphezulu kwe-121 ° C ukuya kwi-145 ° C). Izincamathelisi ezingenazinyibilikisi ngoku zinokugubungela ukubulala iintsholongwane ekuphekeni kwi-121 ° C nangaphantsi.
Ukongeza kwisakhiwo esaziwayo esineeleya ezintathu/ezine, izinto eziphambili ezisetyenziswayo yiPET, AL, NY, kunye neRCPP. Kukwakho nezinye iimveliso zokufutha ezinezinye izakhiwo zezinto ezisetyenziswayo kwimarike, ezifana nokugquma kwe-aluminium ecacileyo, ifilimu ye-polyethylene efuthayo enobushushu obuphezulu, njl. Nangona kunjalo, azisetyenziswanga ngomlinganiselo omkhulu okanye ngobuninzi. Isiseko sokufutha kwazo sisafuna ixesha elide kunye nokuhlolwa kweenkqubo ezininzi.
Amatyala ezicelo kunye neendawo zenkqubo
Kwicandelo lokufutha nokubilisa ngobushushu obuphezulu, iglu yethu isetyenziswe kwisakhiwo esineengqimba ezine zePET/AL/NY/RCPP zokupakishwa kweemveliso zenyama kunye nerayisi etyebileyo kunye neengcambu zelotus, zonke ezinokuthi ziphekwe kwaye zibulawe iintsholongwane kwi-121 ° C. Ukusetyenziswa kwizakhiwo zeplastiki kuquka i-WD8166 kwi-121 ° C izicelo ze-NY/RCPP ezidityanisiweyo, eziye zasetyenziswa kakhulu kwaye zavuthwa; Ulwakhiwo lweplastiki ye-aluminium: Ukusetyenziswa kwe-WD8262 kwi-121 ° C AL/RCPP/nako kuvuthiwe kakhulu.
Kwangaxeshanye, ekuphekeni nasekubulaleni iintsholongwane kwisakhiwo se-aluminium-plastic, ukusebenza kokunyamezela okuphakathi (i-ethyl maltol) kwe-WD8268 nako kulungile. Ukongeza, i-WD8258 ibonakalise ukusebenza kakuhle kwisakhiwo sokupheka se-nylon esiphindwe kabini (i-NY/NY/RCPP) kunye nomaleko we-AL/NY (i-NY yi-corona discharge enye) kwisakhiwo sokupheka se-aluminium foil esinamaleko amane.
Amanyathelo okhuseleko enkqubo：
Okokuqala, kufuneka kumiselwe kwaye kuqinisekiswe ubungakanani beglue. Ubungakanani beglue obucetyiswayo kwiiglue ezingenasombululo buphakathi kwe-1.8-2.5g/m².
Auluhlu lokufuma oluphakathi
Kucetyiswa ukuba kulawulwe ukufuma kwendalo phakathi kwe-40% -70%. Ukufuma kuphantsi kakhulu kwaye kufuneka kufume. Ukufuma okuphezulu kufuna ukufumeliswa. Ngenxa yokuba inxalenye yamanzi kwindalo ithatha inxaxheba kwimpendulo yeglue engenasombululo, ukuthatha inxaxheba kwamanzi ngokugqithisileyo kunokunciphisa ubunzima beglue kwaye kubangele iimpendulo ezithile, ngaloo ndlela kuchaphazele ukusebenza kokumelana nobushushu obuphezulu ngexesha lokupheka. Ke ngoko, kuyimfuneko ukulungisa uqwalaselo lwezixhobo ze-A/B kancinci kwiindawo ezinobushushu obuphezulu kunye nokufuma.
Useto lweparameter yokusebenza kwesixhobo
Misela umlinganiselo woxinzelelo kunye ne-glue ngokweemodeli ezahlukeneyo zezixhobo kunye noqwalaselo.
Iimfuno zezinto eziluhlaza
Ukuthe tyaba okulungileyo, ukufuma kakuhle, ukuncipha kunye nokuba nomxholo wokufuma wefilimu zonke ezi zinto ziyimfuneko ukuze kugqitywe ukupheka izinto ezidityanisiweyo.
Uphuhliso lwexesha elizayo：
Isebenzisa ubuchwepheshe obungenazinyibilikisi ekupakisheni ukupheka ngobushushu obuphezulu, ine:
1. Inzuzo yokusebenza kakuhle, amandla emveliso anokuphuculwa kakhulu.
2. Inzuzo yexabiso: Ubungakanani beglu yokupheka esekwe kwisinyibilikisi esetyenziswayo bukhulu, ngokusisiseko ilawulwa kwi-4.0g/m² Ekhohlo nasekunene, umda awukho ngaphantsi kwe-3.5g/m², Kodwa ubungakanani beglu esetyenziswa kwiglu yokupheka engenasinyibilikisi yi-2.5g/m² Ezinye iimveliso zinobunzima obungaphantsi kwe-1.8g.
3. Iingenelo zokhuseleko kunye nokukhuselwa kwendalo
4. Iingenelo zokonga amandla
Ngamafutshane, ngenxa yeempawu zayo ezizodwa, izincamathelisi ezingenasombululo ziya kuba noluhlu olubanzi lwezicelo kwixesha elizayo ngentsebenziswano yokushicilela imibala, izincamathelisi, kunye namashishini adibeneyo.
