Refrigerated ice packs anowanzo kuumbwa akati wandei akakosha zvinhu zvinonangwa nekupa yakanaka insulation uye kusimba kwakakwana.Zvinhu zvikuru zvinosanganisira:
1. Outer layer zvinhu:
-Nylon: Yakareruka uye yakasimba, inowanzoshandiswa pachikamu chekunze chemhando yepamusoro ice packs.Nylon ine zvakanaka kupfeka kuramba uye kuramba kubvarura.
-Polyester: Imwe inowanzoshandiswa yekunze layer zvinhu, zvakachipa zvishoma pane naironi, uye zvakare ine yakanaka kusimba uye kuramba kubvarura.
-Vinyl: Inokodzera zvikumbiro zvinoda kudzivirira mvura kana nyore kuchenesa nzvimbo.
2. Insulation zvinhu:
-Polyurethane foam: chinhu chakajairika chekuisa insulating, uye chinoshandiswa zvakanyanya mumabhegi echando efiriji nekuda kwekuita kwayo kwemafuta ekupisa uye kusareruka maitiro.
-Polystyrene (EPS) furo: inozivikanwawo se styrofoam, chinhu ichi chinowanzoshandiswa mumabhokisi anotonhora anotakurika uye mamwe enguva imwe chete inotonhora yekuchengetedza mhinduro.
3. Inner lining material:
-Aluminium foil kana metallized firimu: inowanzoshandiswa sechinhu chekushongedza kubatsira kuratidza kupisa uye kuchengetedza kupisa kwemukati.
-Chikafu chegiredhi PEVA (polyethylene vinyl acetate): Ipurasitiki isiri-chepfu inowanzoshandiswa kune yemukati mabhegi echando inosangana zvakananga nezvokudya, uye inonyanya kufarirwa nokuti haina PVC.
4. Filler:
-Gel bhegi: bhegi rine yakakosha gel, iyo inogona kuchengetedza kutonhora kushanda kwenguva yakareba mushure mechando.Gel inowanzogadzirwa nekusanganisa mvura uye polymer (yakadai sepolyacrylamide), dzimwe nguva inochengetedza uye antifreeze inowedzerwa kuvandudza kushanda.
-Mvura yemunyu kana zvimwe zvinogadziriswa: Mamwe mapepa echando akareruka anogona kungova nemvura yemunyu, iyo ine nzvimbo yechando yakaderera kupfuura mvura yakachena uye inogona kupa nguva yakareba yekutonhora panguva yefiriji.
Paunosarudza bhegi rechando rakakodzera refiriji, unofanirwa kufunga kuti zvinhu zvaro zvinosangana nezvido zvako, kunyanya ingave ichida chitupa chekuchengetedza chikafu, uye kana bhegi rechando richida kucheneswa kana kushandiswa munzvimbo dzakati.
