Amaphakethe weqhwa afrijishidi ajwayele ukwakhiwa kwezinto ezibalulekile ezihlose ukuhlinzeka ngokufakwa okuhle nokuqina ngokwanele. Izinto eziphambili zifaka:
1. I-Outer Layer Material:
-Nylon: Engasindi futhi ihlala isikhathi eside, evame ukusetshenziswa kungqimba yangaphandle yamaphakethe weqhwa eliphakeme. I-Nylon inokumelana kahle nokumelana nezinyembezi.
-Polleyester: Okunye okuvame ukusetshenziswa kwesendlalelo, okushibhile kancane kune-nylon, futhi kubuye kube nokuqina okuhle nokumelana nezinyembezi.
-Vinyl: Ilungele izinhlelo zokusebenza ezidinga ukuhlanganisa amanzi noma okulula ukuhlanza izindawo.
2. Izinto zokufakelwa:
-Polyyurethane Foam: Kuyinto evame kakhulu yokufaka okufakwayo, futhi isetshenziswa kabanzi ezikhwameni zeqhwa ezifrijini ngenxa yokusebenza kwayo okuhle kakhulu kokufakelwa okushisayo kanye nezimpawu ezingasindi.
-PolySTrenerene (EPS) Foam: Yaziwa nangokuthi i-Styrofoam, lokhu okuqukethwe kuvame ukusetshenziswa emabhokisini abandayo aphaphathekayo kanye nezisombululo ezibandayo ezibandayo.
3. Indwangu yangaphakathi yokulwa:
I-Aluminum Foil noma ifilimu elenziwe ngensimbi: esetshenziswa kakhulu njengezinto ezisetshenziswayo ukusiza ukukhombisa ukushisa nokugcina izinga lokushisa langaphakathi.
-Food grade Peva (Polyethylene Vinyl Acetate): Izinto ezingezona ezinobuthi ezinobuthi ezisetshenziselwa ungqimba lwangaphakathi lwezikhwama zeqhwa ngokuxhumana ngqo nokudla, futhi kudumile kakhulu ngoba akuqukethe i-PVC.
4. Filler:
-Gel bag: isikhwama esiqukethe i-gel ekhethekile, engagcina umphumela wokupholisa isikhathi eside ngemuva kokuqandeka. Ijeli livame ukwenziwa ngokuxuba amanzi ne-polymer (njenge-polyrylamide), kwesinye isikhathi okulondolozwayo kanye nokulwa nama-antifree kuyengezwa ukwenza ngcono ukusebenza.
-Salt Amanzi noma ezinye izixazululo: Amanye amaphakethe alula ama-Ice angenza kuphela amanzi kasawoti, anendawo ebabazekayo ephansi kunamanzi ahlanzekile futhi anganikeza isikhathi eside sokupholisa ngesikhathi sokuqapha ngesikhathi sokuqapha.
Lapho ukhetha isikhwama seqhwa esiyisiqandisi esiqandisiwe, kufanele ubheke ukuthi impahla yayo ihlangabezana yini nezidingo zakho ezithile, ikakhulukazi noma ngabe idinga isitifiketi sokuphepha kokudla, nokuthi ngabe isikhwama seqhwa sidinga ukuhlanza njalo noma okusetshenziswa ezindaweni ezithile.
