Chifukwa chiyani kapu ya thermos ikufunika kuyesedwa mobwerezabwereza?

Mfundo yotchinjiriza ya kapu ya chitsulo chosapanga dzimbiri ya thermos ndikutulutsa mpweya pakati pa makoma a makapu osanjikiza awiri kuti apange vacuum state. Popeza vacuum imatha kuletsa kufalikira kwa kutentha, imakhala ndi mphamvu yoteteza kutentha. Ndiroleni ndifotokoze mowonjezereka nthawi ino. Mwachidziwitso, kutentha kwapang'onopang'ono kudzipatula kuyenera kukhala ndi mtheradi wa kutchinjiriza. Komabe, kwenikweni, chifukwa cha mapangidwe a kapu yamadzi komanso kulephera kukwaniritsa dziko lonse la vacuum panthawi yopanga, nthawi yotsekemera ya chikho cha thermos ndi yochepa, yomwe imakhalanso yosiyana. Mitundu ya makapu a thermos imakhalanso ndi kutalika kosiyanasiyana.

Ndiye tiyeni tibwerere ku nkhani yathu. Chifukwa chiyani makapu a thermos amafunika kutsukidwa mobwerezabwereza asanachoke kufakitale? Aliyense akudziwa kuti cholinga choyesa vacuum ndikuwonetsetsa kuti kapu iliyonse yamadzi ndi kapu ya thermos yogwira ntchito bwino ikachoka kufakitale, ndikuletsa makapu osasunthika a thermos kuti asayendere kumsika. Nanga n’cifukwa ciani tiyenela kucita zimenezi mobwerezabwereza?

Kubwerezabwereza sikukutanthauza kuchita galasi lamadzi mobwerezabwereza mu nthawi yomweyo. Zimenezo sizikupanga nzeru. Kuyesa mobwerezabwereza kumatanthauza zomwe ziyenera kuchitika pamene fakitale ikhoza kuwononga kapena kuwononga mpweya wa kapu yamadzi. M'malingaliro, mulingo woyesererawu uyenera kutsatiridwa mosamalitsa ndi fakitale iliyonse yamakapu amadzi. Ndi njira iyi yokha yomwe makapu onse a thermos pamsika angatsimikizidwe kukhala ofanana. Ili ndi mphamvu yabwino yotchinjiriza matenthedwe, koma kwenikweni, poganizira kupsinjika kwa ndalama zomwe zimagwiritsidwa ntchito pazachuma komanso mtengo wake, mafakitale ambiri sadzachita mayeso obwereza bwereza pamakapu amadzi.

Kupukuta kukamalizidwa, kuyezetsa vacuum kudzachitika musanayambe kupopera mbewu mankhwalawa. Cholinga chake ndikuwunika zomwe sizinachotsedwe ndikupewa kuwonjezera mtengo wopopera;

Ngati kapu yopoperayo sinasonkhanitsidwe nthawi yomweyo ndipo ikufunika kusungidwa, iyenera kutsukidwanso ikadzatumizidwanso kuchokera mosungiramo. Popeza zambiri zomwe zimapanga makapu amadzi pano zimangopanga zokha kapena zongopanga zokha, sizikunenedwa kuti makapu ena amadzi amatha kukhala ndi zowotcherera zofooka panthawi yowotcherera. Chodabwitsa ichi chidzapangitsa kuti mavuto adziwike poyang'anitsitsa vacuum yoyamba, ndipo dongosololi silingathe kuzindikira vutoli litasungidwa kwa masiku angapo. Malo omwe amawotcherera a Tin Hau amatha kutulutsa mpweya chifukwa cha kukanikiza kwamkati ndi kunja, kotero kuyang'anira vacuum pambuyo pobereka kumatha kutulutsa makapu amadzi amtunduwu. Panthawi imodzimodziyo, chifukwa cha kugwedezeka panthawi yosungira kapena kuyendetsa, getter ya makapu ochepa kwambiri amadzi adzagwa. Ngakhale kugwa kwa makapu ambiri amadzi sikungakhudze magwiridwe antchito a kapu yamadzi, padzakhalabe nthawi zina pomwe getter idzagwa chifukwa cha kugwa kwa getter. Zimayambitsa kutuluka kwa mpweya kuswa vacuum. Mavuto ambiri omwe ali pamwambawa atha kuthetsedwa powunika izi.

Ngati chinthu chomalizidwacho chikufunikabe kusungidwa m’nyumba yosungiramo katundu ndi kusungidwa kwa nthaŵi yaitali chisanatumizidwe, makapu amadzi amene atsala pang’ono kutumizidwa akufunikabe kuti ayesedwenso opanda pake asanatumizidwe. Mayesowa amatha kuzindikira zomwe sizinali zowonekera kale, monga vacuum. Kuwotcherera ndiyeno kuthetsa kwathunthu kapu yamadzi yomwe ili ndi vuto monga kutayikira.

Abwenzi ena angafunse ataona izi, popeza mwanena izi, ndizomveka kuti makapu onse a thermos pamsika ayenera kukhala ndi ntchito yabwino yotchinjiriza. Nchifukwa chiyani anthu amapezabe kuti makapu ena a thermos alibe insulated akagula mabotolo amadzi? Kupatulapo zifukwa zomwe mafakitole ena sayesa mobwerezabwereza kuyesa kwa vacuum, palinso kupuma kwa vacuum komwe kumachitika chifukwa cha makapu amadzi omwe amayamba chifukwa cha mayendedwe akutali, komanso kupuma kwa vacuum komwe kumachitika chifukwa cha makapu amadzi akugwa panthawi yamayendedwe angapo.

Talankhula za njira zambiri zosavuta komanso zosavuta zoyesera kutsekemera kwa makapu amadzi m'nkhani zam'mbuyomu. Anzanu omwe akufunika kudziwa zambiri amaloledwa kuwerenga nkhani zathu zam'mbuyomu.
