Ubukho bongcoliseko kwiipakethe zomkhenkce ikakhulu kuxhomekeke kwimathiriyeli kunye nokusetyenziswa kwazo.Kwezinye iimeko, ukuba imathiriyeli okanye inkqubo yokwenziwa kwepakethe yomkhenkce ayihlangabezani nemigangatho yokhuseleko lokutya, ngenene kunokubakho imiba yosulelo.Nantsi eminye imiba ephambili:
1. Ukwakheka kweekhemikhali:
-Ezinye iipakethi zomkhenkce ezikumgangatho ophantsi zinokuqulatha imichiza eyingozi efana ne-benzene kunye ne-phthalates (i-plasticizer esetyenziswa ngokuqhelekileyo), enokuba yingozi empilweni.Le michiza inokuntywila ekutyeni ngexesha lokusetyenziswa, ngakumbi kwiindawo zobushushu obuphezulu.
2. Umonakalo kunye nokuvuza:
-Ukuba isikhwama seqhwa sonakaliswe okanye sivuza ngexesha lokusetyenziswa, i-gel okanye i-liquid ngaphakathi ingadibana nokutya okanye iziselo.Nangona uninzi lwezigcwalisi zengxowa yomkhenkce zingenatyhefu (ezifana ne-polymer gel okanye isisombululo se-saline), ukudibana ngokuthe ngqo akukacetyiswa.
3. Isiqinisekiso seMveliso:
-Xa ukhetha ipakethe yeqhwa, khangela isiqinisekiso sokhuseleko lokutya, njengemvume ye-FDA.Ezi ziqinisekiso zibonisa ukuba izinto zepakethe yomkhenkce zikhuselekile kwaye zifanelekile ukudibana nokutya.
4. Ukusetyenziswa kunye nokugcinwa okuchanekileyo:
-Qinisekisa ukucoceka kweepakethi zomkhenkce phambi nasemva kokusetyenziswa, kwaye uzigcine kakuhle.Kuphephe ukuhlala kunye nezinto ezibukhali ukuthintela umonakalo.
-Xa usebenzisa i-ice pack, kungcono ukuyibeka kwisikhwama esingenamanzi okanye ukuyisonga ngethawula ukuphepha ukudibanisa ngqo nokutya.
5. Imiba yokusingqongileyo:
-Ukuqwalasela ukhuseleko lokusingqongileyo, iipakethi ze-ice ezinokuphinda zisetyenziswe, kwaye ingqwalasela kufuneka ihlawulwe kwiindlela zokuphinda zisetyenziswe kunye nokulahla iipakethi ze-ice ukunciphisa ukungcoliseka kwendalo.
Ngamafutshane, ukukhetha iipakethi zomkhenkce ezikumgangatho ophezulu kunye neziqinisekisiweyo ngokufanelekileyo, kunye nokusebenzisa nokuzigcina ngokuchanekileyo, kunokunciphisa umngcipheko wongcoliseko.Ukuba kukho iinkxalabo ezikhethekileyo zokhuseleko, unokuba nolwazi olunzulu lwemathiriyeli yemveliso kunye nophononongo lwabasebenzisi ngaphambi kokuthenga.
Amacandelo aphambili kwiipakethi ze-ice efrijini
Iipakethi zomkhenkce ezifakwe efrijini zidla ngokuqulunqwa ngezinto ezininzi ezibalulekileyo ezijolise ekunikeni ubushushu obufanelekileyo kunye nokuqina okwaneleyo.Izinto eziphambili ziquka:
1. Izixhobo zomaleko wangaphandle:
-Inayiloni: Ikhaphukhaphu kwaye iqinile, isetyenziswa ngokuqhelekileyo kumaleko angaphandle eepakethi zomkhenkce ezikumgangatho ophezulu.Inayiloni inokumelana nokunxiba kakuhle kunye nokumelana nokukrazuka.
-I-Polyester: Enye imathiriyeli yangaphandle esetyenziswa ngokuqhelekileyo, inexabiso eliphantsi kunenayiloni, kwaye inokomelela okulungileyo kunye nokungakrazuki.
-Vinyl: Ifanelekile kwizicelo ezifuna ukukhuselwa kwamanzi okanye ukucoceka okulula komgangatho.
2. Imathiriyeli yokugquma:
-I-Polyurethane foam: yinto eqhelekileyo yokugquma, kwaye isetyenziswa ngokubanzi kwiingxowa zomkhenkce efrijini ngenxa yokusebenza kwayo kakuhle kwe-thermal insulation kunye neempawu ezilula.
I-Polystyrene (EPS) igwebu: ekwabizwa ngokuba yi-styrofoam, le nto isetyenziswa ngokuqhelekileyo kwiibhokisi eziphathwayo ezibandayo kunye nezinye izisombululo zexesha elilodwa lokugcina ukubanda.
3. Imathiriyeli yomgca wangaphakathi:
-I-aluminium foil okanye ifilimu ene-metalized: isetyenziswa ngokuqhelekileyo njengezinto zokugqoka ukunceda ukubonakalisa ukushisa kunye nokugcina ukushisa kwangaphakathi.
-Ibakala lokutya i-PEVA (i-polyethylene vinyl acetate): Isixhobo seplastiki esingenabuthi esiqhelekileyo sisetyenziselwa umgca wangaphakathi weengxowa zomkhenkce ngokudibana ngqo nokutya, kwaye ithandwa kakhulu kuba ayinayo i-PVC.
4. Isifaki:
-Ibhegi yeGel: isikhwama esinejel ekhethekileyo, enokugcina isiphumo sokupholisa ixesha elide emva kokukhenkceza.I-Gel ivame ukwenziwa ngokuxuba amanzi kunye ne-polymer (efana ne-polyacrylamide), ngamanye amaxesha i-preservative kunye ne-antifreeze yongezwa ukuphucula ukusebenza.
-Amanzi etyuwa okanye ezinye izisombululo: Ezinye iipakethi ze-ice ezilula zinokuthi zibe namanzi anetyuwa kuphela, anendawo yokukhenkceza engaphantsi kwamanzi acocekileyo kwaye inokubonelela ixesha elide lokupholisa ngexesha lefriji.
Xa ukhetha i-ice bag efanelekileyo efrijini, kufuneka ucinge ukuba ingaba impahla yayo ihlangabezana neemfuno zakho ezithile, ngakumbi ukuba ifuna isatifikethi sokhuseleko lokutya, kwaye ingaba isikhwama se-ice sidinga ukucocwa rhoqo okanye ukusetyenziswa kwiindawo ezithile.
Amalungu aphambili eepakethe zomkhenkce
Ipakethe yomkhenkce enomkhenkce idla ngokuqulatha la malungu alandelayo, ngalinye linemisebenzi ethile yokuqinisekisa ukuba ipakethe yomkhenkce enomkhenkce igcina ngokufanelekileyo ubushushu obuphantsi:
1. Izixhobo zomaleko wangaphandle:
-Inayiloni: Inayiloni yinto ehlala ixesha elide, engenamanzi, kunye nekhaphukhaphu elungele iingxowa zomkhenkce ezifuna ukuhamba rhoqo okanye ukusetyenziswa ngaphandle.
-I-Polyester: I-polyester yenye into eqhelekileyo ehlala isetyenziswa ngokuqhelekileyo kwiqokobhe langaphandle leengxowa zomkhenkce ezikhenkcezileyo, ezinamandla afanelekileyo kunye nokumelana nokunxiba.
2. Umaleko wokugquma:
-I-Polyurethane foam: Yinto esebenza kakhulu yokugquma, kwaye isetyenziswa kakhulu kwiingxowa zomkhenkce ezikhenkcezileyo ngenxa yesakhono sayo sokugcina ubushushu.
-I-Polystyrene (EPS) igwebu: ekwabizwa ngokuba yi-styrene foam, le nto ilula kakhulu isetyenziswa ngokuqhelekileyo kwisiqandisi kunye neemveliso ezikhenkcezisiweyo, ngakumbi kwizisombululo zefriji zexesha elilodwa.
3. Umgca wangaphakathi:
-Ifoyile yeAluminiyam okanye ifilimu enesinyithi: Ezi zixhobo zisetyenziswa ngokuqhelekileyo njengeentsimbi zokunceda ukubonakalisa amandla obushushu kunye nokuphucula iziphumo zokugquma.
-Ibakala lokutya i-PEVA: Le yiplastiki engeyiyo ityhefu esetyenziswa ngokuqhelekileyo kuluhlu lwangaphakathi lweepakethe zomkhenkce, ukuqinisekisa uqhagamshelwano olukhuselekileyo lokutya.
4. Isifaki:
-Gel: I-filler esetyenziswa ngokuqhelekileyo kwiingxowa zomkhenkce yijeli, ehlala iqulethe amanzi, iipolymers (ezifana ne-polyacrylamide) kunye nenani elincinci lezongezo (ezifana ne-preservatives kunye ne-antifreeze).Ezi jeli zinokufunxa ubushushu obuninzi kwaye zikhuphe kancinci isiphumo sokupholisa emva komkhenkce.
-Isisombululo samanzi etyuwa: Kwezinye iipakethe ezilula ze-ice, amanzi etyuwa anokusetyenziswa njengento yokupholisa ngenxa yokuba indawo yokukhenkceza yamanzi anetyuwa ingaphantsi kunamanzi acocekileyo, inika umphumo wokupholisa ixesha elide.
Xa ukhetha iipakethi zeqhwa ezinqabileyo, kubalulekile ukuqinisekisa ukuba izinto ezikhethiweyo zemveliso zikhuselekile, zihambelana nokusingqongileyo, kwaye zinokuhlangabezana neemfuno zakho ezithile, ezifana nokugcinwa kokutya okanye iinjongo zonyango.Okwangoku, qwalasela ubungakanani kunye nokumila kweepakethi ze-ice ukuqinisekisa ukuba zifanelekile kwisitya sakho okanye indawo yokugcina.
