“Thaum sawv ntxov txias, Phauj Li npaj ib khob mis nyuj kub rau nws tus tub xeeb ntxwv thiab muab tso rau hauv nws nyiam tas luav thermos. Tus me nyuam zoo siab coj nws mus kawm ntawv, tab sis tsis tau xav tias lub khob mis nyuj no yuav tsis tsuas yog nws tuaj yeem ua rau nws sov txhua tag kis, tab sis nws ua rau nws muaj teeb meem kev noj qab haus huv uas tsis xav txog. Thaum tav su, tus menyuam tau tsim cov tsos mob ntawm kiv taub hau thiab xeev siab. Tom qab maj mam mus rau hauv tsev kho mob, nws tau pom tias qhov teeb meem nteg nrog lub khob thermos zoo li tsis muaj teeb meem - -Nws tso cov khoom tsis zoo. Zaj dab neeg tseeb no ua rau peb xav tob heev: Puas yog lub khob thermos uas peb xaiv rau peb cov menyuam muaj kev nyab xeeb tiag tiag?
Cov khoom siv xaiv: kev noj qab haus huv moat ntawm cov me nyuam lub thermos khob
Thaum xaiv lub khob thermos, thawj qhov uas yuav tsum tau them sai sai rau yog cov khoom siv. Feem ntau cov thermos khob hauv khw yog ua los ntawm stainless hlau thiab yas. Tab sis tsis yog tag nrho cov ntaub ntawv tsim nyog rau kev sib cuag zaub mov mus ntev. Qhov tseem ceeb ntawm no yog siv cov zaub mov-qib stainless hlau. Piv nrog rau cov hlau tsis zoo tib yam, cov zaub mov qib stainless hlau ua tau zoo dua ntawm kev tiv thaiv corrosion thiab kev nyab xeeb, thiab yuav tsis tso cov khoom tsis zoo vim siv mus ntev.
Ua ib qho kev sim ua piv txwv, cov kws tshawb fawb tau muab cov hlau tsis huv zoo tib yam thiab cov zaub mov-qib stainless hlau hauv qhov chaw acidic. Cov txiaj ntsig tau pom tias cov ntsiab lus ntawm cov hlau hnyav hauv cov dej ntub dej ntawm cov hlau tsis zoo li qub tau nce ntxiv, thaum cov zaub mov qib stainless hlau pom yuav luag tsis muaj kev hloov pauv. Qhov no txhais tau hais tias yog siv cov khoom siv tsis zoo, kev haus dej mus ntev lossis lwm yam dej haus yuav ua rau muaj kev phom sij rau menyuam yaus.
Txawm hais tias lub khob yas thermos yog lub teeb, lawv qhov zoo sib txawv. Cov yas zoo nkauj muaj kev nyab xeeb rau kev siv, tab sis muaj ntau cov khoom yas uas tsis zoo ntawm lub khw uas tuaj yeem tso cov khoom tsis zoo xws li bisphenol A thaum raug kub hnyiab. Raws li kev tshawb fawb, BPA raug cuam tshuam rau menyuam yaus cov kab mob endocrine thiab tseem ua rau muaj teeb meem loj hlob. Yog li ntawd, thaum xaiv lub khob yas, xyuas kom meej tias nws tau sau tias "BPA-dawb."
Thaum txheeb xyuas cov ntaub ntawv zoo, koj tuaj yeem txiav txim siab los ntawm kev txheeb xyuas cov ntaub ntawv ntawm cov khoom lag luam. Lub khob thermos tsim nyog yuav qhia meej txog cov khoom siv thiab seb nws puas yog qib zaub mov ntawm daim ntawv lo. Piv txwv li, cov zaub mov-qib stainless hlau feem ntau sau tias "304 stainless hlau" lossis "18/8 stainless hlau." Cov ntaub ntawv no tsis yog tsuas yog ib qho kev lees paub ntawm qhov zoo, tab sis kuj yog ib qho kev txhawj xeeb ncaj qha rau menyuam yaus txoj kev noj qab haus huv.
Qhov txuj ci tiag tiag ntawm lub khob thermos: nws tsis yog qhov kub xwb
Thaum muas lub khob thermos, thawj qhov uas tib neeg feem ntau them rau yog cov nyhuv rwb thaiv tsev. Txawm li cas los xij, muaj ntau dua rau kev rwb thaiv tsev dua li kev tswj xyuas qhov kub ntawm cov dej kub. Nws yeej muaj feem cuam tshuam txog menyuam kev haus dej haus cawv thiab kev noj qab haus huv.
Nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem thermal rwb thaiv tsev ntawm lub khob thermos. Cov khob thermos zoo feem ntau siv ob txheej stainless hlau qauv nrog lub tshuab nqus tsev hauv nruab nrab. Cov qauv no tuaj yeem tiv thaiv kom tsis txhob muaj cua sov los ntawm thermal conduction, convection thiab hluav taws xob, yog li tswj qhov kub ntawm cov kua rau lub sijhawm ntev. Qhov no tsis yog tsuas yog lub hauv paus ntsiab lus ntawm physics, tab sis kuj yog ib qho tseem ceeb ntawm kev ntsuas qhov zoo ntawm lub khob thermos.
Lub sijhawm tuav lub sijhawm ntev tsis yog qhov ntsuas nkaus xwb. Lub khob thermos zoo tiag tiag nyob hauv nws lub peev xwm los tswj qhov kub thiab txias. Piv txwv li, qee lub khob thermos tuaj yeem khaws cov kua dej hauv qhov kub thiab txias ntev txog li ob peb teev, tiv thaiv cov dej kub kub los yog txias dhau, uas yog qhov tseem ceeb rau kev tiv thaiv koj tus menyuam qhov ncauj qhov ncauj. Cov dej uas kub dhau tuaj yeem ua rau kub hnyiab hauv koj lub qhov ncauj, thaum dej txias dhau los tsis ua rau koj lub cev sov.
Raws li kev tshawb fawb, qhov dej haus uas tsim nyog yuav tsum nyob nruab nrab ntawm 40 ° C thiab 60 ° C. Yog li ntawd, lub khob thermos uas tuaj yeem tswj dej kub hauv qhov no rau 6 mus rau 12 teev yog qhov kev xaiv zoo tshaj plaws. Hauv kev ua lag luam, ntau lub khob thermos thov kom muaj peev xwm ua kom cov zaub mov sov li 24 teev lossis ntev dua. Tab sis qhov tseeb, lub peev xwm khaws cia kub ntau tshaj 12 teev yog tsis muaj kev siv rau cov menyuam yaus. Hloov chaw, nws yuav ua rau muaj kev hloov pauv ntawm cov dej zoo thiab cuam tshuam rau kev nyab xeeb ntawm kev haus dej.
Ua tib zoo saib xyuas cov menyuam yaus txoj kev siv tus cwj pwm, cov nyhuv rwb thaiv tsev ntawm lub khob thermos yuav tsum sib phim lawv cov dej num txhua hnub. Piv txwv li, hauv tsev kawm ntawv, tus menyuam yuav tsum haus dej kub lossis dej sov thaum sawv ntxov. Yog li ntawd, xaiv lub khob uas tuaj yeem ua kom sov li ntawm 4 mus rau 6 teev yog txaus kom tau raws li cov kev xav tau niaj hnub.
Lub hau ntawm lub khob thermos tsis yog tsuas yog ib qho cuab yeej rau kaw lub thawv, tab sis kuj yog thawj kab ntawm kev tiv thaiv rau menyuam yaus txoj kev nyab xeeb. Lub hau zoo yog tsim los nrog cov dej tsis haum, qhib thiab kaw yooj yim, thiab kev nyab xeeb hauv siab, uas yog qhov tseem ceeb tshwj xeeb rau cov menyuam yaus.
Leak-proof kev ua tau zoo yog ib qho ntawm cov txheej txheem tseem ceeb rau kev ntsuas lub hau. Hom thermos khob ntawm kev ua lag luam tuaj yeem yooj yim ua kua dej vim yog lub hau tsim tsis zoo. Qhov no tsis yog tsuas yog ib qho teeb meem me me rau cov khaub ncaws kom ntub, tab sis kuj yuav ua rau cov me nyuam ntog vim kev khaus khaus. Kev soj ntsuam ntawm qhov ua rau ntog ntawm cov menyuam kawm ntawv preschool qhia tias kwv yees li 10% ntawm cov dej tsaws tsag muaj feem cuam tshuam rau cov dej nchuav. Yog li ntawd, xaiv lub hau nrog cov khoom sib khi zoo tuaj yeem zam qhov kev pheej hmoo zoo li no.
Qhov qhib thiab kaw tsim ntawm lub hau yuav tsum yooj yim thiab siv tau yooj yim, haum rau tus menyuam txoj kev loj hlob ntawm tes. Lub hau uas nyuaj dhau los yog xav tau ntau lub zog yuav tsis tsuas yog ua rau nws nyuaj rau cov menyuam yaus siv, tab sis kuj tseem tuaj yeem ua rau kub hnyiab vim siv tsis raug. Raws li kev txheeb cais, ntau qhov xwm txheej kub hnyiab tshwm sim thaum menyuam yaus sim qhib lub khob thermos. Yog li ntawd, lub hau tsim uas yooj yim qhib thiab kaw thiab tuaj yeem ua haujlwm nrog ib txhais tes yog qhov tseem ceeb los ua kom muaj kev nyab xeeb ntawm cov menyuam yaus.
Cov khoom siv thiab qhov me me ntawm lub hau kuj yog ib qho tseem ceeb ntawm kev nyab xeeb. Tsis txhob siv cov khoom me me lossis cov qauv tsim uas yooj yim kom poob tawm, uas tsis tsuas yog txo qhov kev pheej hmoo ntawm kev ua tsis taus pa, tab sis kuj tseem ua rau lub neej ua haujlwm ntawm lub khob thermos. Piv txwv li, qee lub khob thermos zoo siv lub hau tsim ua ke uas tsis muaj qhov me me, uas muaj kev nyab xeeb thiab ruaj khov.
