Iingxowa zokupakisha zevacuumukusuka ekusebenzeni komqobo kunokwahlulwa kwiingxowa ezingenasithintelo ze-vacuum, i-medium-barrier vacuum bags kunye ne-high-barrier vacuum bags;ukusuka kulwahlulo olusebenzayo, lunokwahlulwa lube ziingxowa zokufunxa ezinobushushu obuphantsi, iingxowa zokufunxa ezinobushushu obuphezulu, iingxowa zokufunxa ezikwaziyo ukumelana ne-puncture, iingxowa ezicuthekayo, iingxowa zokumisa kunye neziziphu.
Ebusweni bezinto ezahlukeneyo zokupakisha kunye neempawu ezahlukeneyo zemveliso, indlela yokukhetha izinto zokupakisha ezifanelekileyo ze-vacuum ibe sisicelo sokuvelisa ngokwenene kufuneka sisonjululwe.
Indlela yokukhethaiingxowa zokupakisha zevacuumkwiintlobo ezahlukeneyo zeemveliso?
Ngenxa yokuba iimveliso ezahlukeneyo zineemfuno ezahlukeneyo zezinto zokupakisha, ngoko ke kufuneka senze ukhetho lwezinto eziphathekayo ngokweempawu zemveliso, kubandakanywa: nokuba kulula ukuwohloka, izinto ezikhokelela ekudakaleni (ukukhanya, amanzi okanye i-oksijeni, njl.), ifom yemveliso, ubulukhuni bomphezulu wemveliso, iimeko zokugcina, ubushushu bokwenza inzala, njl.njl. Ibhegi yokufunxa kakuhle, ingekuko ukuba ineempawu ezininzi, kodwa ukubona ukuba ifanelekile na imveliso.
1. Imveliso enemilo eqhelekileyo okanye indawo ethambileyo.
Kwiimveliso ezinemilo eqhelekileyo okanye umphezulu othambileyo, njengemveliso yesoseji yenyama, iimveliso zesoya, njl.n kwizinto eziphathekayo.Ngoko ke, kwiimveliso ezinjalo, ukusetyenziswa ngokubanzi kwe-OPA / PE isakhiwo sesikhwama.Ukuba imfuno yokuvala ubushushu obuphezulu (ngaphezu kwe-100 ℃), ingasetyenziselwa i-OPA / CPP isakhiwo, okanye ukusetyenziswa kwe-PE ephezulu yokumelana nobushushu njengomgangatho wokutywina ubushushu.
2. Iimveliso ezinobunzima obuphezulu bomphezulu.
Iimveliso ezinje ngemveliso yenyama enamathambo, ngenxa yokuqina komphezulu ophakamileyo kunye nokuqina okuqinileyo, kulula ukugqobhoza ibhegi kwinkqubo yokucoca kunye nokuthutha, ngoko ke iingxowa zezi mveliso kufuneka zibe nokumelana nokugqobhoza okuhle kunye nokusebenza kwe-buffering, ungakhetha. I-PET/PA/PE okanye i-OPET/OPA/CPP iingxowa ze-vacuum eziphathekayo.Ukuba ubunzima bemveliso bungaphantsi kwe-500g, unokuzama ukusebenzisa i-OPA / OPA / PE isakhiwo sesikhwama, le ngxowa inemveliso efanelekileyo yokuguquguquka, umphumo ongcono we-vacuum, ngelixa ungatshintshi ukuma kwemveliso.
3. Iimveliso ezinokonakala.
Iimveliso zenyama ezinobushushu obuphantsi kunye nezinye iimveliso ezithanda ukubola kwaye zifuna inzala yobushushu obuphantsi bokuqina kwengxowa ayiphezulu, kodwa ifuna iipropathi ezigqwesileyo zomqobo, ngoko ke unokukhetha ifilimu ecocekileyo edibeneyo, efana ne-PA/PE / EVOH / PA / PE isakhiwo sefilimu, ungasebenzisa kwakhona i-compounding eyomileyo, njengefilimu ye-PA / PE, ungasebenzisa kwakhona izinto zokugqoka i-K.Iimveliso zobushushu obuphezulu zingasetyenziswa iingxowa zokushwabana zePVDC okanye iibhegi ezomileyo.
Ifanelekile kwiimpawu zokupakisha ze-vacuum zemathiriyeli nganye.
1. I-PE ifanelekile ukusetyenziswa kobushushu obuphantsi, i-RCPP ifanelekile ukusetyenziswa kwe-steaming ephezulu.
2. I-PA kukunyusa amandla omzimba, kunye nokuchasana kwe-puncture.
3. I-AL aluminium foil inokunyusa ukusebenza komqobo kunye nomthunzi wokukhanya.
4. I-PET inokunyusa amandla omatshini kunye nokuqina okulungileyo.
