Vacuum izikhwama zokupakishakusukela ekusebenzeni kwesithiyo kungahlukaniswa ngezikhwama ze-vacuum ezingezona izithiyo, izikhwama ze-vacuum ze-medium-barrier kanye nezikhwama ze-vacuum eziphezulu;kusukela esigabeni sokusebenza, ingahlukaniswa ngezikhwama ze-vacuum ezisezingeni eliphansi, izikhwama ze-vacuum ezishisa kakhulu, izikhwama ze-vacuum ezivimbela ukubhoboza, izikhwama ezinciphayo, izikhwama zokumisa kanye nezikhwama zoziphu.
Ebusweni bezinto ezihlukahlukene zokupakisha kanye nezici ezihlukahlukene zomkhiqizo, indlela yokukhetha izinto zokupakisha ze-vacuum ezifanele isibe isicelo sokukhiqiza sangempela okufanele sixazululwe.
Indlela yokukhethaizikhwama zokupakisha ze-vacuumngezinhlobo ezahlukene zemikhiqizo?
Ngenxa yokuthi imikhiqizo ehlukene inezidingo ezahlukene zezinto zokupakisha, ngakho-ke kufanele sikhethe izinto ezibonakalayo ngokusho kwezimpawu zomkhiqizo, kufaka phakathi: noma ngabe kulula ukuwohloka, izici eziholela ekuwohlokeni (ukukhanya, amanzi noma umoya-mpilo, njll.), ifomu lomkhiqizo, ubulukhuni bobuso bomkhiqizo, izimo zokugcina, izinga lokushisa lokuvala inzalo, njll. Isikhwama se-vacuum esihle, hhayi esinezici eziningi, kodwa ukubona ukuthi siwufanele yini umkhiqizo.
1. Umkhiqizo onomumo ojwayelekile noma indawo ethambile.
Ngemikhiqizo enomumo ojwayelekile noma indawo ethambile, efana nemikhiqizo yesoseji yenyama, imikhiqizo yesoya, njll., akudingekile ukudinga amandla aphezulu wemishini, udinga kuphela ukucabangela umgoqo wento kanye nomthelela wokushisa inzalo. endabeni.Ngakho-ke, emikhiqizweni enjalo, ukusetshenziswa okuvamile kwesakhiwo se-OPA / PE sesikhwama.Uma isidingo sokuvalwa kwezinga lokushisa eliphezulu (ngaphezulu kuka-100 ℃), singasetshenziswa isakhiwo se-OPA/CPP, noma ukusetshenziswa kwe-PE ekwazi ukumelana nokushisa okuphezulu njengongqimba oluvala ukushisa.
2. Imikhiqizo enobulukhuni obuphezulu.
Imikhiqizo efana nemikhiqizo yenyama enamathambo, ngenxa yokuqina kobuso obuphezulu kanye ne-protrusions eqinile, ukubhoboza isikhwama kalula ngesikhathi se-vacuum nokuthutha, ngakho-ke izikhwama zale mikhiqizo zidinga ukuphikiswa okuhle kokubhoboza nokusebenza kwe-buffering, ungakhetha. Izikhwama ze-vacuum ezibonakalayo ze-PET/PA/PE noma i-OPET/OPA/CPP.Uma isisindo somkhiqizo singaphansi kuka-500g, ungazama ukusebenzisa i-OPA/OPA/PE isakhiwo sesikhwama, lesi sikhwama sinokuguquguquka okuhle komkhiqizo, umphumela we-vacuum ongcono, kuyilapho ungashintshi ukuma komkhiqizo.
3. Imikhiqizo ebolayo.
Imikhiqizo yenyama esezingeni eliphansi kanye neminye imikhiqizo ethambekele ekuwohlokeni futhi edinga inzalo yokushisa ephansi yamandla esikhwama ayiphezulu, kodwa idinga izakhiwo ezinhle kakhulu zokuvimbela, ngakho-ke ungakhetha ifilimu e-co-extruded ehlanzekile, njenge-PA/PE /EVOH/PA/PE isakhiwo sefilimu, ungasebenzisa futhi i-compounding eyomile, njengefilimu ye-PA/PE, ungasebenzisa futhi impahla yokugqoka ye-K.Imikhiqizo yokushisa ephezulu ingasetshenziswa izikhwama zokushwabana ze-PVDC noma izikhwama ezomile.
Ifanele izici zokupakisha ze-vacuum zento ngayinye.
1. I-PE ifanele ukusetshenziswa kwezinga lokushisa eliphansi, i-RCPP ifanele ukusetshenziswa kwe-steaming ephezulu.
2. I-PA ukukhulisa amandla omzimba, ukumelana nokubhoboza.
3. Ucwecwe lwe-AL aluminium lungakhuphula ukusebenza komgoqo futhi lube nomthunzi ukukhanya.
4. I-PET ingakhuphula amandla emishini kanye nokuqina okuhle.
