Kuv yog khob, kuv lub taub hau me me, twist qhib yog haus dej qhov ncauj, kuv lub cev rog nrog cov khaub ncaws muaj yeeb yuj.kuv ntxim hlub kawg li!Thiab kuv cov khaub ncaws ua los ntawmstainless hlau.
Peb yog cov khoom tsim nyog ntawm lub neej niaj hnub, yuav luag txhua tus muaj lawv.Thiab peb vim hais tias ntawm thermal rwb thaiv tsev yam ntxwv, yog ntau nyiam los ntawm cov neeg.Boiling dej nyob rau hauv ib lub khob zoo tib yam, tom qab ib lub sij hawm ntawm kub mus rau qhov txias, qhov no thermal conduction yog ib tug natural txoj cai, tab sis lub thermos khob tuaj yeem ua rau cov dej hauv khob tom qab ib lub sij hawm tseem tuaj yeem tswj qhov kub thiab txias. tus thawj, yog li cov neeg tshwj xeeb tshaj yog nyiam hom nothermos khob.
“Lub tshuab nqus tsev vacuum“, ntau tus neeg siv peb haus dej txhua hnub.Tab sis koj puas paub vim li cas cov dej kub hauv khob tsis txias tom qab ob peb teev?Koj puas paub tias peb lub hauv paus ntsiab lus ua li cas nrog lub tshuab nqus tsev?
Nyob rau hauv 1892, Scottish physicist thiab chemist James Dewar tau tsim lubkhob nqus tsev vacuum.Dewar tag nrho lub neej ua haujlwm feem ntau yog los ntawm kev tshawb fawb ntawm cryogenics.Yuav kom kawm txog roj liquefaction, nws xav tau ib lub thawv nrog zoo thermal rwb thaiv tsev.Lub sijhawm ntawd, cov nyhuv thermal rwb thaiv tsev ntawm lub thawv tsis zoo, thiab cov cua sov tau yooj yim poob.Yog li Dewar xav txog lub tshuab nqus tsev uas hloov tsis tau cua sov.Nws tus ntsuj plig ntawm kev tshawb nrhiav thiab kev tsim kho tshiab tau ua rau nws qhov kev tsim ua tiav.Lub thawv tau hu ua "Dewar" thiab tom qab ntawd los ua tuskhob nqus tsev vacuumpeb siv tam sim no.
Los ntawm xyoo 1950, kev muag khoom ntawm lub tshuab nqus tsev vacuum tau mus txog qhov siab tshaj plaws vim tib neeg xav tau.Thaum lub sij hawm no, lub khob nqus tsev vacuum tau nqa hauv tsev neeg noj mov, taug kev hauv hiav txwv thiab chaw pw hav zoov.Tom qab ntawd, cov khoom ntawmkhob nqus tsev vacuumtau txhim kho tsis tu ncua,stainless hlauthiab ceramics tau dhau los ua cov ntaub ntawv tseem ceeb ntawm lub tank sab hauv thiab lub plhaub.Lub peev xwm ntawm kev sib cais huab cua yog txhim kho, uas ua rau cov cua sov txuag cov nyhuv ntawm lub tshuab nqus tsev kub preservation khob zoo dua thiab zoo dua.
