Kubathandi bezemidlalo yasebusika, izifudumezi zezandla zingasho umehluko phakathi kokubiza usuku kusenesikhathi nokudlala ngaphandle isikhathi eside ngangokunokwenzeka.Eqinisweni, noma ubani omelana namakhaza angase alingeke ukuba azame izikhwama ezincane ezilahlwayo ezikhipha ukufudumala ngemizuzwana nje echayeke emoyeni.
Izifudumezi zezandla zisukela emakhulwini eminyaka lapho abantu base-Japan babesebenzisa amatshe ashisayo ukufudumala izandla zabo, izifudumezi zezandla eziphathwayo ezigcwele umlotha oshisayo kwakuyinguqulo eyalandela.Kulezi zinsuku, ungathenga izifudumezi-zandla ezihlukahlukene ngokusekelwe kumaphakethe ebhethri nophethiloli olula, kodwa izifudumezi zezandla ezilahlwayo zithembele ngokuphelele kukhemistri.
Izifudumezi zezandla ezilahlwayo zivula ukushisa kuma-mittens akho ngendlela yokusabela okushisayo, okuvele kudale ukugqwala.Isikhwama ngasinye siqukethe impushana yensimbi, usawoti, amanzi, into emuncayo, kanye nekhabhoni ecushiwe.Lapho isikhwama sikhishwa ephaketheni laso langaphandle, umoya-mpilo ugeleza unqamule isembozo sesikhwama esikwazi ukungena kalula.Njengoba kukhona usawoti namanzi, i-oksijini isabela nge-iron powder etholakala ngaphakathi ukuze yakhe i-iron oxide (Fe2O3) futhi ikhulule ukushisa.
Izinto ezimuncayo zingaba ukhuni olugayiwe, i-polymer efana ne-polyacrylate, noma i-silicon-based mineral ebizwa ngokuthi i-vermiculite.Kuyasiza ukugcina umswakama ukuze ukusabela kwenzeke.Ikhabhoni ecushiwe isiza ukuhlakaza ngokulinganayo ukushisa okukhiqiziwe.
Umehluko omkhulu phakathi kwezifudumezi zezandla ezilahlwayo nezinye izinguqulo ezisebenziseka kabusha ngamakhemikhali asetshenziselwa ukukhiqiza ukusabela okukhipha ukushisa.Izifudumezi zezandla ezisebenziseka kabusha azinayo insimbi kodwa kunalokho zisebenzisa isixazululo esine-supersaturated ye-sodium acetate ekhipha ukushisa njengoba kukhanya.Ukubilisa iphakethe elisetshenzisiwe kubuyisela isisombululo esimweni saso sokugcwala ngokweqile.Izifudumezi zezandla ezisebenza ngomoya azikwazi ukuphinda zisetshenziswe.
Izifudumezi zezandla ezilahlwayo azigcini nje ngokuvimbela abantu ukuthi bagodole kakhulu.Ama-Comfort Brand warmers aphinde athengise izifudumezi ezinzima ezingasiza izinhlanzi zasezindaweni ezishisayo zikwazi ukusinda lapho zihamba endaweni ebandayo.
