Kuvapo kwekusvibiswa mumapaki echando kunonyanya kuenderana nezvinhu zvavo uye kushandiswa.Mune zvimwe zviitiko, kana zvinhu kana maitiro ekugadzira echando pack asingasviki mazinga ekuchengetedza chikafu, panogona kunge paine nyaya dzekusvibiswa.Heano mamwe makuru ekufungisisa:
1. Kemikari yakagadzirwa:
-Mamwe emhando yakaderera ice packs anogona kunge aine makemikari anokuvadza akadai sebenzene uye phthalates (anowanzo shandiswa plasticizer), anogona kuunza njodzi kune hutano.Makemikari aya anogona kupinda muchikafu panguva yekushandiswa, kunyanya munzvimbo dzinopisa.
2. Kukuvadzwa uye kuvuza:
-Kana bhegi rechando rakakuvadzwa kana kuputika panguva yekushandiswa, gel kana mvura mukati inogona kusangana nechikafu kana zvinwiwa.Kunyangwe akawanda ice bag mafirita asina chepfu (senge polymer gel kana saline solution), kuonana zvakananga hakusati kwakurudzirwa.
3. Product certification:
-Paunosarudza ice pack, tarisa chikafu chekuchengetedza chitupa, senge FDA mvumo.Izvi zvitupa zvinoratidza kuti zvinhu zve ice pack zvakachengeteka uye zvakakodzera kusangana nechikafu.
4. Kushandisa uye kuchengetedza kwakarurama:
-Iva nechokwadi chekuchena kwemazaya echando pamberi uye mushure mekushandisa, uye uzvichengete nemazvo.Dzivisa kugarisana nezvinhu zvinopinza kudzivirira kukuvara.
-Paunenge uchishandisa ice pack, zviri nani kuti uiise muhombodo isina mvura kana kuiputira netauro kuti usapinda zvakananga nechikafu.
5. Nyaya dzezvakatipoteredza:
-Tichifunga nezvekuchengetedzwa kwezvakatipoteredza, reusable ice packs inogona kusarudzwa, uye kutarisisa kunofanirwa kubhadharwa kune kudzokorodza uye kuraswa nzira dzemazaya echando kuderedza kusvibiswa kwezvakatipoteredza.
Muchidimbu, kusarudza mapaketi echando emhando yepamusoro uye akakodzera, uye kushandisa nekuachengeta nemazvo, zvinogona kuderedza njodzi yekusvibiswa.Kana paine zvakakosha zvekuchengetedza, unogona kuve neruzivo rwakadzama rwezvigadzirwa zvezvigadzirwa uye wongororo yevashandisi usati watenga.
Izvo zvikamu zvikuru zvefiriji ice packs
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.
Izvo zvakakosha zvemazaya echando akaomeswa
Iyo ice pack yakaomeswa nechando inowanzo sanganisira zvinotevera zvikamu zvikuru, chimwe nechimwe chine mabasa chaiwo ekuona kuti iyo chando pack inochengetedza tembiricha yakaderera.
1. Outer layer zvinhu:
-Nylon: Nylon chinhu chakasimba, chisingapindi mvura, uye chakareruka chakakodzera mabhegi echando akaomeswa nechando anoda kugara achifambisa kana kushandiswa kunze.
-Polyester: Polyester chimwe chinhu chakajairika chakasimba chinowanzo shandiswa kune kunze goko rechando mabhegi echando, ane simba rakanaka uye kupfeka kuramba.
2. Insulation layer:
-Polyurethane foam: Inoshanda zvakanyanya insulating zvinhu, uye inoshandiswa zvakanyanya mumabhegi echando akaomeswa nechando nekuda kwekugona kwayo kuchengetedza kupisa.
-Polystyrene (EPS) foam: inozivikanwawo se styrene foam, ichi chinhu chisina kuremerwa chinowanzoshandiswa mufiriji uye zvigadzirwa zvechando, kunyanya mune imwe-nguva yekugadzirisa mafiriji.
3. Inner lining:
-Aluminium foil kana metallized film: Zvinhu izvi zvinowanzo shandiswa semicheka kubatsira kuratidza kupisa kwesimba uye kuwedzera insulation mhedzisiro.
-Chikafu giredhi PEVA: Iyi isiri-chepfu yepurasitiki zvinhu zvinowanzoshandiswa kune yemukati layer ye ice packs, kuve nechokwadi chekubata kwakachengeteka nechikafu.
4. Filler:
-Gel: Iyo inowanzoshandiswa yekuzadza mabhegi echando ndeye gel, iyo inowanzo ine mvura, mapolymers (akadai se polyacrylamide) uye zvishoma zvekuwedzera (zvakadai sekuchengetedza uye antifreeze).Aya gel anogona kutora kupisa kwakawanda uye zvishoma nezvishoma kuburitsa kutonhorera mushure mechando.
-Mushonga wemvura yemunyu: Mune mamwe mapeji echando ari nyore, mvura yemunyu inogona kushandiswa sechinhu chinotonhorera nokuti nzvimbo yechando yemunyu yakaderera pane yemvura yakachena, ichipa kutonhora kwenguva refu.
Paunosarudza mazaya echando akaomeswa, zvakakosha kuve nechokwadi chekuti zvigadzirwa zvakasarudzwa zvakachengeteka, zvine hushamwari, uye zvinogona kuzadzisa zvaunoda chaizvo, sekuchengetedza chikafu kana zvinangwa zvekurapa.Zvichakadaro, funga saizi uye chimiro cheaizi mapaketi kuti ave nechokwadi chekuti akakodzera mudziyo wako kana nzvimbo yekuchengetera.
