Chifukwa chiyani madontho amadzi ang'onoang'ono amafupika pomwe kapu yachitsulo chosapanga dzimbiri ya thermos yadzazidwa ndi madzi ozizira?

Pamene ndinalemba mutu wa nkhaniyi, ndinaganiza kuti owerenga ambiri angaganize kuti funsoli ndi lopusa? Ngati muli madzi ozizira mkati mwa kapu yamadzi, kodi sizinthu zachilendo zokomera madzi pamwamba pa kapu yamadzi?

Tiyeni tiyike pambali zongoganiza zanga. Pofuna kuthetsa kutentha m'chilimwe chotentha, tonsefe timadziwa kumwa zakumwa zoziziritsa kukhosi. Kapu ya zakumwa zoziziritsa kukhosi imatha kuthetsa kutentha nthawi yomweyo ndi kutipangitsa kumva kuziziritsa kosangalatsa nthawi yomweyo kutenthako sikungatheke.

Sipatenga nthawi mutagwira chakumwa chozizira m'manja mwanu kuti madontho amadzi ayambe kukhazikika kunja kwa botolo la zakumwa. Chakumwa chikamazizira kwambiri, madontho amadzi amachulukanso. Izi zili choncho chifukwa kutentha kwa chakumwa kumakhala kochepa kusiyana ndi kutentha kwa mpweya, ndipo nthunzi yamadzi mumlengalenga imakumana ndi kutentha kochepa kusiyana ndi kutentha kwachilengedwe. Kutentha kukakhala koopsa, amaunjikana pamodzi, ndipo ngati akwera kwambiri, amapanga madontho amadzi.

Koma kodi izi zikuyenera kuchitikanso ndi makapu azitsulo zosapanga dzimbiri za thermos? Yankho liyenera kukhala ayi.

Chikho chachitsulo chosapanga dzimbiri cha thermos chimatengera kapangidwe kawiri. Vacuum imapangidwa pakati pa chipolopolo chakunja ndi thanki yamkati kudzera mu vacuum. Pamene vacuum ili yokwanira, ndiye kuti mphamvu yotchinga imakhala yabwino. Ichi ndichifukwa chake makapu amadzi omwe aliyense amagula tsiku lililonse amakhala otsekeredwa. Chifukwa chomwe makapu ena amadzi amakhala ndi zotsatira zabwino kwambiri zotchinjiriza.

Chikho cha thermos sichingatseke kutentha kokha, komanso kutentha kochepa. Chifukwa chake, pakapu yachitsulo chosapanga dzimbiri cha thermos itadzazidwa ndi madzi ozizira, pasakhale madontho amadzi opindika pamwamba pa kapu yamadzi. Ngati madontho amadzi awoneka, zimangotanthauza kuti kapu yamadzi imatsekedwa. Ubwino wake ndi wosauka.

Timakhazikika popereka makasitomala ndi ntchito zonse za dongosolo la chikho cha madzi, kuchokera ku mapangidwe azinthu, mapangidwe apangidwe, chitukuko cha nkhungu, mpaka pokonza pulasitiki ndi zitsulo zosapanga dzimbiri. Kuti mudziwe zambiri za makapu amadzi, chonde siyani uthenga kapena mutitumizireni.
