Ngaba wakha wazibuza ukuba iziphuzo ezishushu zihlala zishushu njani kwi-thermos iiyure?Esi sithuba sebhlog siya kutyhila iimfihlo ezisemva kokusebenza okuphezulu kwe-thermos kunye nokuphonononga isayensi enomdla emva komsebenzi wayo.Ukususela ekuzalweni kwabo ukuya kwindima yabo kubomi bethu bemihla ngemihla, makhe singene nzulu kwindlela ezisebenza ngayo ezi zikhongozeli zikrelekrele.
Yintoni iflaski yokufunxa?
I-vacuum flask, ekwabizwa ngokuba yi-vacuum flask, sisikhongozeli esibiyelwe kabini esenziwe ngeglasi okanye intsimbi engatyiwayo.Iibhotile ezimbini zohlulwe ngesithuba sokufunxa, zenza indawo yokufunxa.Olu lwakhiwo lunciphisa ukuhanjiswa kobushushu, lwenza ukuba i-thermos ilungele ukugcina iziselo ezishushu nezibandayo kubushushu obufunwayo ixesha elide.
Inkqubo yokugquma:
Ukuze siqonde indlela i-thermos esebenza ngayo, kufuneka sihlolisise kwizinto ezisisiseko ezinegalelo kwiimpawu zayo zokukhusela:
1. Isingxobo sangaphakathi nangaphandle:
Iindonga zangaphakathi nangaphandle ze-thermos zihlala zenziwe ngensimbi engenasici, iglasi okanye iplastiki.Insimbi engenasici ibonelela ngeempawu ezigqwesileyo zokukhusela, ngelixa iglasi inika ukucaca okuphezulu kunye nokumelana neekhemikhali.Ezi zixhobo zisebenza njengomqobo, ukuthintela ukushisa kwangaphandle ekufikeleleni kwimixholo yeflask.
2. Vacuum seal:
Isitywina sevacuum senziwe phakathi kweendonga zangaphakathi nangaphandle.Inkqubo ibandakanya ukususa umoya kwi-gap, ukushiya i-vacuum space kunye ne-molecule encinci yegesi.Ekubeni ukuhanjiswa kobushushu nge-convection kunye ne-convection kufuna i-medium efana nomoya, i-vacuum ithintela ukuhanjiswa kwamandla okushisa ukusuka kwindawo yangaphandle.
3. Ukwaleka okubonakalayo:
Ezinye ii-thermoses zinentsimbi ekhanyayo ngaphakathi eludongeni olungaphandle.Oku kugquma kunciphisa imitha yobushushu, ukuhanjiswa kobushushu ngamaza ombane.Inceda ukugcina ubushushu bemixholo yeflask ngokubonisa umva kwimitha ye-thermal ekhutshwayo.
4. Isithinteli:
Isivalo okanye isiciko se-thermos, ngokuqhelekileyo senziwe ngeplastiki okanye irabha, sidlala indima ebalulekileyo ekugcineni i-vacuum ngokunciphisa ukuhanjiswa kobushushu ngokuvula ukugcina i-vacuum.Isithinteli sikwathintela ukuchitheka kunye nokuvuza, ukuqinisekisa ukuba ubushushu buhlala bunjalo.
ISayensi eNgemva kwe-Insulation:
Umsebenzi we-thermos usekelwe ikakhulu kwiindlela ezintathu zokuthintela ukuhanjiswa kobushushu:
1. Ukuqhuba:
Ukwenziwa kukudluliselwa kobushushu ngokudibana ngqo phakathi kwezinto.Kwi-thermos, i-gap ye-vacuum kunye ne-insulation inhibit conduction phakathi kweendonga zangaphakathi nangaphandle, ukukhusela ubushushu be-ambient yangaphandle ukuba buchaphazele iziqulatho ngaphakathi.
2. Ukuhambisa:
I-Convection ixhomekeke kwintshukumo yolwelo okanye igesi.Ekubeni iindonga zangaphakathi kunye nezangaphandle ze-thermos zihlulwe zi-vacuum, akukho moya okanye ulwelo lokuququzelela ukuhanjiswa, ukunciphisa kakhulu ukulahleka kobushushu okanye inzuzo evela kwindalo.
3. Imitha:
Ubushushu bunokukhutshelwa ngamaza ombane abizwa ngokuba yimitha.Ngelixa isigqubuthelo esibonakalisayo kwiindonga zangaphakathi zeflask kunciphisa ukusasazeka kwemitha yobushushu, ivacuum ngokwayo isebenza njengomqobo ogqwesileyo ngokuchasene nolu hlobo lokudluliselwa kobushushu.
ukuququmbela:
I-thermos ngumsebenzi obalaseleyo wobunjineli, usebenzisa imigaqo yokufudumeza ubushushu ukubonelela nge-insulation ethembekileyo.Ngokudibanisa iipropathi zokukhusela umsantsa wevacuum kunye nezixhobo ezinciphisa ukuqhuba, ukuhanjiswa kunye nemitha, ezi flasks ziqinisekisa ukuba isiselo osithandayo sihlala kubushushu obufunwayo kangangeeyure ezininzi.Ngoko ke kwixesha elizayo uyonwabela ikomityi eshushu yekofu okanye iti ehlaziyayo yomkhenkce evela kwi-thermos, jonga kwinzululwazi entsonkothileyo yokuyigcina ngendlela othanda ngayo.
