Ndiri mukombe, musoro wangu mudiki, twist kuvhurika ndiko kunwa mvura muromo, muviri wangu wakafuta nehembe dzine mavara.Ndakanaka!Uye mbatya dzangu dzakagadzirwa nesimbi isina ngura.
Isu ndisu zvinodikanwa zvehupenyu hwemazuva ano, anenge munhu wese anazvo.Uye isu nekuda kweiyo thermal insulation hunhu, inonyanya kufarirwa nevanhu.Mvura inofashaira mukapu yakajairwa, mushure menguva kubva pakupisa kusvika kunotonhora, rudzi urwu rwekupisa ruchi mutemo wechisikigo, asi iyo thermos kapu inogona kugadzira mvura yemukombe mushure menguva yenguva inogona kuramba ichichengetedza tembiricha yakafanana. yepakutanga, saka vanhu kunyanya vanoda rudzi urwuthermos mukombe.
“Vacuum cup“, vanhu vazhinji vanotishandisa kunwa mvura mazuva ese.Asi unoziva here kuti sei mvura inopisa iri mukapu isingatonhodzi mushure memaawa mashoma?Unoziva here kuti musimboti wedu une chekuita nevacuum?
Muna 1892, nyanzvi yefizikisi yekuScotland uye kemisitiri James Dewar akagadziravacuum cup.Basa rose rehupenyu hwaDewar rainyanya kudzidza nezve cryogenics.Kuti adzidze kunyunguduka kwegasi, aida chigaba chine insulation yakanaka yekupisa.Panguva iyoyo, thermal insulation effect yemudziyo yakanga isina kunaka, uye kupisa kwaiva nyore kurasikirwa.Saka Dewar akafunga chivharo chisingakwanise kufambisa kupisa.Mweya wake wekuongorora nekuvandudza zvinhu zvakaita kuti chigadzirwa chake chibudirire.Chigaba chacho chakanzi "Dewar" uye gare gare chakava iyovacuum cuptinoshandisa ikozvino.
Pakazosvika ma1950, kutengeswa kwevacuum mugs kwakasvika pakakwirira nekuda kwekuda kwevanhu.Munguva iyi, makapu evacuum aitakurwa mumapikiniki emhuri, nzendo dzegungwa uye kumisasa yemumunda.Gare gare, zvinhu zvevacuum cupyakavandudzwa nguva dzose,simbi isina ngurauye ceramics yakava zvinhu zvikuru zvemukati tank uye shell.Kugona kwekuzviparadzanisa nemhepo kunokwidziridzwa, izvo zvinoita kuti kupisa kwekuchengetedza mhedzisiro yevacuum yekupisa yekuchengetedza mukombe kuve nani uye zvirinani.
