Tikulamulirani ozizira: thumba isothermal

Kumayambiriro kwa zaka za m'ma 21, vuto yosungira kutsitsimuka kwa mankhwala ngakhale zofunika monga izo zinali mazana zapitazo. Makamaka zofunika funso limeneli kwa okonda kuyenda mtunda wautali. Kodi kukhala ndi mtima wabwino mankhwala angadye panjira?

Kumapeto kwa zaka za m'ma otsiriza, njira anapezeka. Panali wapadera isothermal ozizira thumba. Kodi chipangizo ichi? Ndipo kodi ntchito?

Chotero thumba (amalimata chidebe) n'kofunika kwambiri ngati mukufuna mankhwala anu ngati n'zotheka anakhalabe mwatsopano. Nthawi zambiri izo ntchito kwa kuzirala ndi kusunga zakudya mazira mayiko. Koma pali zina pamene ntchito chakudya chotentha. anthu otchedwa zitsanzo izi ozizira thumba, koma si zoona ndithu. firiji aliyense ali chipangizo yozizira. Isothermal thumba ulibe. Iwo amagwira ntchito yake chifukwa batire ozizira. M'kupita kwa nthawi, kutentha mkati amakhala chimodzimodzi monga kutentha yozungulira. nthawi yaitali bwanji thumba adzasunga mankhwala boma mazira zimadalira ntchito zake. Childs, muli ndi kupulumutsa ozizira ndi bwino.

Zonse za katundu zothandiza thumba thermo zimadalira batire ozizira. Zinthu pulasitiki preform, wodzala ndi njira yapadera mchere. The zambiri mwa zipangizozi mu beseni, motalikira izo kupitiriza kutentha otsika. No batire isothermal thumba akhoza kusunga ozizira kwa maola 3, naye nthawi kuti akhoza zayamba kuchuluka.

Kodi ubwino wa chitsanzo chimenechi?

1. Isothermal thumba angathandizire kutentha onse ozizira ndi otentha.
2. Yaying'ono ndi kunyamula - zigawo ziwiri zimene zimapangitsa zimenezi nkhani otchuka.
3. Chabwino kapangidwe, matumba ambiri kuyang'ana kaso ndi zooneka bwino.
4. Odalirika chitetezo. Mitundu yonse ya zippers, zotulutsira adzithandiza mankhwala bwinobwino. Safety maloko adzatsekeredwa kukonza iwo mkati kuteteza mwangozi kutsegula kwa thumba.
5. Mkati zogwiritsa ntchito. Kawirikawiri pali makontena angapo mkati thumba. Mwachitsanzo, chifukwa zitini kapena mabotolo. Ndipo ena a iwo ndi lonse la mbale ndi zambiri. Zonsezi zimathandiza kupeza mankhwala mosavuta ndi conveniently.

Ndipo, mwinamwake funso lalikulu: "Kodi kuyang'ana posankha chitsanzo"

Choyamba, ngati mukufuna kathumba lotsekedwa, kudziwa voliyumu. Mphamvu iwo ndi osiyana - 5 malita 30. Zingakhale zokwanira buku avareji chidebe banja lililonse.

Zofunika Chinthu chachiwiri ndi nkhani ya kumanga thumba isothermal. Kawirikawiri ntchito imeneyi cholinga nayiloni, pulasitiki, poliyesitala. Iwo cholimba ndi zosavuta kukonza. Desirably, mkati anali PVC chuma ndi katundu chimawala.

Kenako, kulabadira chomasuka kayendedwe thumba. Izo ziyenera kukhala cholembera wapadera. Ngati inu kukhala pa chitsanzo mwachilungamo capacious, thumba ayenera akhale okonzeka ndi mawilo wodzigudubuza. Apo ayi, kusamutsa izo, koma wodzazidwa ndi ambiri mankhwala kungakhale kovuta.

Pomwepo pa sitolo onani kudalilika ndi chitetezo cha mayendedwe. Chinthu chachikulu ndi thumba sanatsegule zokha. Kuti tichite zimenezi, payenera kukhala wapadera maloko chitetezo.

Ngati inu bwinobwino katundu ndi ndinu okhutitsidwa ndi izo zonse, omasuka kugula Thermos. Iye mokhulupirika kwa zaka kubwera.
