“Ngentsasa ebandayo, uMakazi uLi walungiselela umzukulwana wakhe ikomityi yobisi olushushu waza walugalela kwikhathuni yakhe ayithandayo. Umntwana wayithatha ngovuyo esikolweni, kodwa akazange acinge ukuba le ndebe yobisi ayinakukwazi ukumgcina efudumele intsasa yonke, kodwa yamzisela ingxaki yempilo engalindelekanga. Emva kwemini, umntwana wavelisa iimpawu zesiyezi kunye nesicaphucaphu. Emva kokubaleka esibhedlele, kwafunyaniswa ukuba ingxaki yayikwikomityi yethermos eyayibonakala ingenabungozi——Ikhupha izinto eziyingozi. Eli bali lokwenyani lisenza sicinge nzulu: Ngaba iikomityi ze-thermos esizikhethela abantwana bethu zikhuselekile ngokwenene?
Ukukhethwa kwezinto eziphathekayo: i-moat yezempilo yeekomityi ze-thermos zabantwana
Xa ukhetha indebe ye-thermos, into yokuqala okumele uyibeke ingqalelo yimpahla. Uninzi lweekomityi ze-thermos eziqhelekileyo kwiimarike zenziwe ngensimbi engenasici kunye neplastiki. Kodwa akuzona zonke izinto ezifanelekileyo zoqhagamshelwano lokutya ixesha elide. Into ephambili apha kukusebenzisa insimbi engenasici yokutya. Xa kuthelekiswa nentsimbi eqhelekileyo, insimbi engenasici yokutya yenza ngcono malunga nokumelana nokubola kunye nokhuseleko, kwaye ayiyi kukhulula izinto ezinobungozi ngenxa yokusetyenziswa kwexesha elide.
Sithatha uhlolisiso njengomzekelo, izazinzulu zantywilisela intsimbi eqhelekileyo engenastainless nentsimbi yokutya ekumgangatho ophezulu kwindawo eneasidi. Iziphumo zabonisa ukuba umxholo wentsimbi enzima kwisisombululo sokufunxa sentsimbi yentsimbi eqhelekileyo yanda kakhulu, ngelixa intsimbi yokutya ye-stainless steel yabonisa phantse akukho tshintsho. Oku kuthetha ukuba xa kusetyenziswa izinto ezikumgangatho ophantsi, ukusela amanzi ixesha elide okanye ezinye iziselo kunokubeka impilo emngciphekweni ebantwaneni.
Nangona iikomityi zeplastiki ze-thermos zikhaphukhaphu, umgangatho wazo uyahluka. Iiplastiki ezikumgangatho ophezulu zikhuselekile ukuba zingasetyenziswa, kodwa kukho inani elikhulu leemveliso zeplastiki ezikumgangatho ophantsi kwimarike ezinokukhupha izinto eziyingozi ezifana ne-bisphenol A xa zisesichengeni sobushushu obuphezulu. Ngokophando, ukuvezwa kwe-BPA kunokuchaphazela iinkqubo ze-endocrine zabantwana kwaye kubangele iingxaki zophuhliso. Ke ngoko, xa ukhetha ikomityi yeplastiki, qiniseka ukuba ibhalwe “i-BPA-free.”
Xa uchonga izixhobo ezikumgangatho ophezulu, unokugweba ngokujonga ulwazi kwileyibhile yemveliso. Ikomityi ye-thermos efanelekileyo iya kubonisa ngokucacileyo uhlobo lwezinto eziphathekayo kunye nokuba ibakala lokutya kwileyibhile. Umzekelo, intsimbi etyiwayo yodidi lokutya idla ngokubhalwa njenge "304 stainless steel" okanye "18/8 stainless steel." Olu lwazi alukho nje isiqinisekiso somgangatho, kodwa kunye nokukhathazeka ngokuthe ngqo kwimpilo yabantwana.
Ubuchule bokwenyani bekomityi ye-thermos: akusiyo nje iqondo lokushisa
Xa kuthengwa ikomityi ye-thermos, into yokuqala abantu abaninzi abayiqwalaselayo yimpembelelo ye-insulation. Noko ke, kukho okungakumbi kunokugcina ubushushu bamanzi ashushu. Eneneni ibandakanya imikhwa yokusela nempilo yabantwana.
Kubalulekile ukuqonda umgaqo we-thermal insulation yekomityi ye-thermos. Iikomityi eziphezulu ze-thermos zihlala zisebenzisa i-double-layer stainless steel structure kunye ne-vacuum layer phakathi. Esi sakhiwo sinokuthintela ubushushu ukuba buphulukene ne-thermal conduction, i-convection kunye ne-radiation, ngaloo ndlela igcina ubushushu bolwelo ixesha elide. Lo ayingomgaqo osisiseko wefiziksi kuphela, kodwa ikwayinto ephambili ekuvavanyeni umgangatho wendebe ye-thermos.
Ubude bexesha lokubamba ayisiyiyo yodwa ikhrayitheriya. Ikomityi ebalaseleyo ye-thermos ilele kumandla ayo okulawula ubushushu ngokuchanekileyo. Ngokomzekelo, ezinye iikomityi ze-thermos zinokugcina ulwelo ngaphakathi kwinqanaba elithile lobushushu ukuya kwiiyure ezininzi, ukuthintela amanzi ashushu ukuba ashushu kakhulu okanye abande kakhulu, okubalulekileyo ekukhuseleni i-mucosa yomlomo yomntwana wakho. Amanzi ashushu kakhulu anokubangela ukutshisa emlonyeni wakho, ngelixa amanzi abandayo kakhulu engakwazi ukugcina umzimba wakho ushushu.
Ngokophononongo, ubushushu obufanelekileyo bamanzi okusela kufuneka bube phakathi kwama-40°C kunye nama-60°C. Ke ngoko, ikomityi ye-thermos enokugcina ubushushu bamanzi phakathi kolu luhlu kangangeeyure ezi-6 ukuya kwezili-12 ngokungathandabuzekiyo lolona khetho lufanelekileyo. Kwiimarike, iikomityi ezininzi ze-thermos zithi ziyakwazi ukugcina ukutya kushushu kwiiyure ze-24 okanye nangaphezulu. Kodwa eneneni, amandla okugcina ubushushu angaphezulu kweeyure ezili-12 akusebenzi kubantwana. Endaweni yoko, kunokubangela utshintsho kumgangatho wamanzi kwaye kuchaphazele ukhuseleko lokusela.
Uthathela ingqalelo imikhwa yokusetyenziswa kwabantwana, isiphumo sokugquma kwekomityi ye-thermos kufuneka sihambelane nemisebenzi yabo yemihla ngemihla. Ngokomzekelo, kwimeko yesikolo, umntwana kusenokufuneka asele amanzi ashushu okanye adikidiki ngeeyure zakusasa. Ngoko ke, ukukhetha ikomityi ekwazi ukufudumala ngokufanelekileyo kwiiyure ezi-4 ukuya kwezi-6 kwanele ukuhlangabezana neemfuno zemihla ngemihla.
Isivalo sekomityi ye-thermos ayisona nje isixhobo sokuvala isitya, kodwa kunye nomgca wokuqala wokukhusela ukhuseleko lwabantwana. Isivalo somgangatho ophezulu senzelwe ukuchasana nokuvuza, ukuvula nokuvala lula, kunye nokhuseleko engqondweni, ezibaluleke kakhulu kubantwana abasebenzayo.
Ukusebenza kobungqina bokuvuza yenye yeendlela eziphambili zokuvavanya iziciko. Iikomityi ze-thermos eziqhelekileyo kwimarike zinokubangela ukuvuza kwamanzi ngenxa yoyilo olungafanelekanga lwesiciko. Oku akuyongxaki encinci kuphela yokuba iimpahla zibe manzi, kodwa zinokubangela ukuba abantwana bawe ngengozi ngenxa yeemeko ezimtyibilizi. Uhlalutyo lwezizathu zokuwa kwabafundi abangekaqala ukuya esikolweni lubonise ukuba malunga ne-10% yokuwa yayinxulumene neziselo ezichithekileyo. Ngoko ke, ukukhetha isiciko esineempawu zokutywina ezintle kunokuphepha ngokufanelekileyo iingozi ezinjalo.
Uyilo lokuvula kunye nokuvala isiciko kufuneka kube lula kwaye kulula ukuyisebenzisa, ifanelekile kwinqanaba lokuphuhlisa isandla somntwana. Isiciko esintsokothileyo okanye esifuna amandla amaninzi asiyi kwenza kube nzima kubantwana kuphela ukusisebenzisa, kodwa sinokubangela ukutshisa ngenxa yokusetyenziswa ngokungafanelekanga. Ngokwezibalo, inani elikhulu leengozi zokutsha zenzeke xa abantwana bezama ukuvula ikomityi ye-thermos. Ke ngoko, uyilo lwesiciko ekulula ukuluvula nokuvala kwaye lunokusetyenziswa ngesandla esinye lubalulekile ekuqinisekiseni ukhuseleko lwabantwana.
Izinto eziphathekayo kunye neenxalenye ezincinci zesivalo nazo ziyinxalenye ebalulekileyo yokhuseleko. Gwema ukusebenzisa iinxalenye ezincinci okanye uyilo olulula ukuwa, olunganciphisi nje umngcipheko wokuphazamiseka, kodwa lwandisa ubomi benkonzo yekomityi ye-thermos. Umzekelo, ezinye iikomityi ze-thermos ezikumgangatho ophezulu zisebenzisa uyilo oludityanisiweyo lwesiciko olungenazo ndawo zincinci, zombini zikhuselekile kwaye zihlala ixesha elide.
