Yenziwa njani i-liner yebhotile ye-thermos?
Ukwakhiwa kweflask ye-thermos ayinzima. Kukho ibhotile yeglasi ephindwe kabini embindini. Amacandelo amabini ayakhutshwa kwaye afakwe ngesilivere okanye i-aluminium. Imeko yevacuum inokuphepha ukuhanjiswa kobushushu. Iglasi ngokwayo ngumqhubi ombi wobushushu. Iglasi ecwecwe ngesilivere inokugqama ngaphakathi kwesikhongozeli ngaphandle. Amandla obushushu abonakaliswa ngasemva. Emva koko, ukuba ulwelo olubandayo lugcinwe ebhotileni, ibhotile ikhusela amandla obushushu avela ngaphandle ukuba angangeni ebhotileni.
Isivalo sebhotile ye-thermos ngokuqhelekileyo senziwe nge-cork okanye iplastiki, zombini akukho lula ukuqhuba ubushushu. Igobolondo yebhotile ye-thermos yenziwe nge-bamboo, iplastiki, isinyithi, i-aluminium, insimbi engenasici kunye nezinye izinto. Umlomo webhotile ye-thermos unegasket yerabha kwaye umzantsi webhotile unesihlalo serabha esime njengesitya. Ezi zisetyenziselwa ukulungisa isinyi seglasi ukuthintela ukungqubana neqokobhe. .
Indawo embi kakhulu yebhotile ye-thermos ukugcina ubushushu kunye nokubanda kujikeleze i-bottleneck, apho ubushushu obuninzi bujikeleza ngokuqhuba. Ngoko ke, i-bottleneck ihlala ifutshane kangangoko kunokwenzeka ngexesha lokwenziwa. Ubukhulu bomthamo kunye nomlomo omncinci webhotile ye-thermos, ngcono umphumo wokufakelwa. Kwiimeko eziqhelekileyo, isiselo esibandayo kwibhotile sinokugcinwa kwi-4 kwiiyure ze-12. c ngeenxa zonke. Bilisa amanzi nge-60. c ngeenxa zonke.
Iibhotile ze-thermos zinxulumene ngokusondeleyo nomsebenzi kunye nobomi babantu. Isetyenziselwa ukugcina imichiza kwiilabhoratri kunye nokugcina ukutya neziselo ngexesha leepikiniki kunye nemidlalo yebhola. Kwiminyaka yakutshanje, iindlela ezininzi ezintsha zongezwa kwiibhotile ze-thermos, kubandakanywa neebhotile ze-thermos zoxinzelelo, iibhotile ze-thermos zoqhagamshelwano, njl.
