“Ngosuku lwasekuseni olubanda kakhulu, u-Anti uLi walungisela umzukulu wakhe inkomishi yobisi olushisayo wayeseluthela ku-thermos opopayi awuthandayo. Ingane yayisa esikoleni ngenjabulo, kodwa ayizange icabange ukuthi le nkomishi yobisi yayingeke nje Ikwazi ukumgcina efudumele ekuseni, kodwa yamlethela inkinga yezempilo eyayingalindelekile. Ntambama, umntwana waba nezimpawu zesiyezi nesicanucanu. Ngemva kokuphuthunyiswa esibhedlela, kwatholakala ukuthi inkinga yayikunkomishi ye-thermos eyayibonakala ingenangozi——Ikhipha izinto eziyingozi. Le ndaba yeqiniso isenza sicabange sijule: Ingabe izinkomishi ze-thermos esizikhethela izingane zethu ziphephe ngempela?
Ukukhetha impahla: umsele wezempilo wezinkomishi ze-thermos zezingane
Lapho ukhetha inkomishi ye-thermos, into yokuqala okufanele uyinake yizinto ezibonakalayo. Izinkomishi ezivame kakhulu ze-thermos emakethe zenziwe ngensimbi engagqwali nepulasitiki. Kodwa akuzona zonke izinto ezilungele ukuxhumana nokudla kwesikhathi eside. Okubalulekile lapha ukusebenzisa insimbi engagqwali yezinga lokudla. Uma kuqhathaniswa nensimbi engagqwali evamile, insimbi engagqwali yezinga lokudla isebenza kangcono ngokumelana nokugqwala nokuphepha, futhi ngeke ikhiphe izinto eziyingozi ngenxa yokusetshenziswa isikhathi eside.
Uma sithatha ucwaningo njengesibonelo, ososayensi bacwilisa insimbi engagqwali evamile nensimbi engagqwali yezinga lokudla endaweni ene-asidi. Imiphumela yabonisa ukuthi insimbi esindayo esixazululweni sokumanzisa sensimbi engagqwali evamile yanda kakhulu, kuyilapho insimbi engagqwali yezinga lokudla ayizange ishintshe. Lokhu kusho ukuthi uma kusetshenziswa izinto ezisezingeni eliphansi, ukuphuza amanzi isikhathi eside noma ezinye iziphuzo kungaba yingozi empilweni yezingane.
Nakuba izinkomishi ze-thermos zepulasitiki zingasindi, izinga lazo liyahlukahluka. Amapulasitiki ekhwalithi ephezulu aphephile ukusetshenziswa, kodwa kunenani elikhulu lemikhiqizo yepulasitiki yekhwalithi ephansi emakethe engase ikhiphe izinto eziyingozi njenge-bisphenol A lapho zichayeke emazingeni okushisa aphezulu. Ngokocwaningo, ukuchayeka kwe-BPA kungase kuthinte izinhlelo ze-endocrine zezingane futhi kubangele nezinkinga zokukhula. Ngakho-ke, lapho ukhetha inkomishi yepulasitiki, qiniseka ukuthi ibhalwe “i-BPA-free.”
Lapho uhlonza izinto zekhwalithi ephezulu, ungahlulela ngokubheka ulwazi olukulebula yomkhiqizo. Inkomishi ye-thermos efanelekayo izobonisa ngokucacile uhlobo lwezinto ezibonakalayo nokuthi iyibanga lokudla yini kulebula. Isibonelo, insimbi engagqwali yezinga lokudla ivamise ukubizwa ngokuthi “304 stainless steel” noma “18/8 stainless steel.” Lolu lwazi aluyona nje isiqinisekiso sekhwalithi, kodwa futhi nokukhathazeka okuqondile ngempilo yezingane.
Ikhono langempela lendebe ye-thermos: akulona nje izinga lokushisa
Lapho uthenga inkomishi ye-thermos, into yokuqala abantu abaningi abayinakayo umphumela wokufakelwa. Nokho, kukhona okungaphezu nje kokulondoloza izinga lokushisa lamanzi ashisayo. Empeleni kuhilela imikhuba yokuphuza nempilo yezingane.
Kubalulekile ukuqonda isimiso sokushisa esishisayo senkomishi ye-thermos. Izinkomishi zekhwalithi ephezulu ze-thermos ngokuvamile zisebenzisa uhlaka oluphindwe kabili lwensimbi engagqwali enongqimba lwe-vacuum phakathi. Lesi sakhiwo singavimbela ukushisa ekulahlekeni ngokusebenzisa i-thermal conduction, convection kanye nemisebe, ngaleyo ndlela kugcinwe izinga lokushisa loketshezi isikhathi eside. Lokhu akusona nje isimiso esiyisisekelo se-physics, kodwa futhi isici esibalulekile ekuhloleni ikhwalithi yendebe ye-thermos.
Ubude besikhathi sokubamba akuwona kuphela umbandela. Inkomishi ye-thermos enhle kakhulu ilele ekhonweni layo lokulawula izinga lokushisa ngokunembile. Isibonelo, ezinye izinkomishi ze-thermos zingagcina uketshezi ngaphakathi kwezinga lokushisa elithile kuze kube amahora ambalwa, ukuvimbela amanzi ashisayo ukuthi ashise kakhulu noma abande kakhulu, okubalulekile ekuvikeleni ulwelwesi lomlomo lwengane yakho oluthambile. Amanzi ashisa kakhulu angabangela ukusha emlonyeni wakho, kanti amanzi abandayo kakhulu awakusizi ukugcina umzimba wakho ufudumele.
Ngokocwaningo, izinga lokushisa elifanele lamanzi okuphuza kufanele libe phakathi kuka-40°C no-60°C. Ngakho-ke, inkomishi ye-thermos engagcina izinga lokushisa lamanzi ngaphakathi kwalolu hlu amahora angu-6 kuya kwangu-12 ngokungangabazeki iyisinqumo esihle. Emakethe, izinkomishi eziningi ze-thermos zithi ziyakwazi ukugcina ukudla kufudumele amahora angu-24 noma ngaphezulu. Kodwa eqinisweni, amandla okugcina ukushisa angaphezu kwamahora angu-12 awasebenzi ezinganeni. Kunalokho, kungase kubangele izinguquko kukhwalithi yamanzi futhi kuthinte ukuphepha kokuphuza.
Uma kucatshangelwa imikhuba yokusetshenziswa kwezingane, umphumela wokufakwa kwenkomishi ye-thermos kufanele futhi uhambisane nemisebenzi yazo yansuku zonke. Ngokwesibonelo, esikoleni, ingane ingase idinge ukuphuza amanzi ashisayo noma asivivi phakathi namahora asekuseni. Ngakho-ke, ukukhetha inkomishi engakwazi ukufudumala ngokuphumelelayo phakathi kwamahora angu-4 kuya kwangu-6 kwanele ukuhlangabezana nezidingo zansuku zonke.
Isembozo sendebe ye-thermos akuyona nje ithuluzi lokuvala isitsha, kodwa futhi umugqa wokuqala wokuvikela ukuphepha kwezingane. Isivalo sekhwalithi ephezulu sidizayinelwe ukumelana nokuvuza, ukuvuleka nokuvala kalula, nokuphepha engqondweni, okubaluleke kakhulu ezinganeni ezikhuthele.
Ukusebenza kokuvikela ukuvuza kungenye yezindlela eziyinhloko zokuhlola izivalo. Izinkomishi ezijwayelekile ze-thermos emakethe zingadala kalula ukuvuza koketshezi ngenxa yokwakheka kwesivalo esingafanele. Lokhu akuyona nje inkinga encane yokuthi izingubo zibe manzi, kodwa futhi kungase kubangele ukuba izingane ziwe ngephutha ngenxa yezimo ezishelelayo. Ukuhlaziywa kwezimbangela zokuwa kwezingane zasenkulisa kuveze ukuthi cishe u-10% wokuwa uhlobene neziphuzo ezichithiwe. Ngakho-ke, ukukhetha isembozo esinezakhiwo ezinhle zokuvala kungagwema ngokuphumelelayo izingozi ezinjalo.
Umklamo wokuvula nokuvalwa kwesembozo kufanele kube lula futhi kulula ukuyisebenzisa, kufanelekile ezingeni lokuthuthukiswa kwesandla somntwana. Isivalo esiyinkimbinkimbi kakhulu noma esidinga amandla amaningi ngeke senze kube nzima ukuthi izingane zisisebenzise, kodwa futhi singase sibangele ukusha ngenxa yokusebenzisa ngendlela engafanele. Ngokwezibalo, inani elikhulu lezingozi zokusha zenzeka lapho izingane zizama ukuvula inkomishi ye-thermos. Ngakho-ke, umklamo wesivalo okulula ukuwuvula nokuvala futhi ongasebenza ngesandla esisodwa ubalulekile ekuqinisekiseni ukuphepha kwezingane.
Izinto ezibonakalayo nezingxenye ezincane zesivalo nazo ziyizingxenye ezibalulekile zokuphepha. Gwema ukusebenzisa izingxenye ezincane noma imiklamo elula ukuwa, engagcini nje ukunciphisa ingozi yokuphefumula, kodwa futhi yandisa impilo yesevisi yenkomishi ye-thermos. Isibonelo, ezinye izinkomishi zekhwalithi ephezulu ze-thermos zisebenzisa idizayini yesivalo esihlanganisiwe engenazo izingxenye ezincane, kokubili okuphephile futhi okuhlala isikhathi eside.
