Wake wazibuza ukuthi iziphuzo ezishisayo zihlala zishisa kanjani ku-thermos amahora?Lokhu okuthunyelwe kwebhulogi kuzodalula izimfihlo ezingemuva kokusebenza okuphezulu kokufakwa kwe-thermos futhi kuhlole isayensi ekhangayo engemuva komsebenzi wayo.Kusukela ekuzalweni kwabo kuya endimeni yabo ekuphileni kwethu kwansuku zonke, ake singene sijule ngokuthi lezi zitsha ezihlakaniphile zisebenza kanjani.
Iyini i-vacuum flask?
I-vacuum flask, evame ukubizwa ngokuthi i-vacuum flask, isitsha esinezindonga ezimbili esenziwe ngengilazi noma insimbi engagqwali.La mabhodlela amabili ahlukaniswa yisikhala sevacuum, enze indawo yokuhlanza.Lokhu kwakhiwa kunciphisa ukudluliswa kokushisa, okwenza i-thermos ibe ilungele ukugcina iziphuzo ezishisayo nezibandayo ezingeni lokushisa elifunekayo isikhathi eside.
Inqubo ye-insulation:
Ukuze siqonde ukuthi i-thermos isebenza kanjani, sidinga ukuphenya ezingxenyeni eziyisisekelo ezifaka izici zayo zokuvikela:
1. Isiqukathi sangaphakathi nesingaphandle:
Izindonga zangaphakathi nangaphandle ze-thermos ngokuvamile zenziwe ngensimbi engagqwali, ingilazi noma ipulasitiki.Insimbi engagqwali inikeza izakhiwo ezinhle kakhulu zokuvikela, kuyilapho ingilazi inikeza ukucaca okuphezulu nokumelana namakhemikhali.Lezi zinto zisebenza njengesithiyo, ezivimbela ukushisa kwangaphandle ekufinyeleleni okuqukethwe kwe-flask.
2. Vacuum seal:
Ivacuum seal yenziwa phakathi kwezindonga zangaphakathi nezingaphandle.Le nqubo ihilela ukususa umoya esikhaleni, kushiye indawo yokungena esinama-molecule amancane egesi.Njengoba ukudluliswa kokushisa nge-convection kanye ne-convection kudinga i-medium efana nomoya, i-vacuum ivimbela ukudluliswa kwamandla ashisayo kusuka endaweni yangaphandle.
3. I-Reflective coating:
Amanye ama-thermose ane-metallic coating ngaphakathi kodonga olungaphandle.Lokhu kunamathela kunciphisa imisebe eshisayo, ukudluliswa kokushisa ngamagagasi kagesi.Isiza ukugcina izinga lokushisa lokuqukethwe kweflask ngokubuyisela emuva imisebe eshisayo ekhishiwe.
4. Isivalo:
Isivalo noma isivalo se-thermos, ngokuvamile esenziwe ngepulasitiki noma ngerabha, sidlala indima ebalulekile ekugcineni indawo engenalutho ngokunciphisa ukudluliswa kokushisa ngembobo ukuze kugcinwe isikhala.Isivalo siphinde sinqande ukuchitheka nokuvuza, siqinisekise ukuthi ukufakwa kwamanzi kuhlala kuqinile.
Isayensi Behind Insulation:
Umsebenzi we-thermos usekelwe ikakhulukazi ezindleleni ezintathu zokuvimbela ukudluliswa kokushisa:
1. Ukuqhuba:
Ukuqhuba ukudlulisa ukushisa ngokuthintana okuqondile phakathi kwezinto.Ku-thermos, igebe le-vacuum kanye nokwahlukanisa kuvimbela ukuhamba phakathi kwezindonga zangaphakathi nezingaphandle, kuvimbele izinga lokushisa langaphandle ukuthi lingathinti okuqukethwe ngaphakathi.
2. I-Convection:
I-Convection incike ekunyakazeni koketshezi noma igesi.Njengoba izindonga zangaphakathi nezangaphandle ze-thermos zihlukaniswe nge-vacuum, awukho umoya noma uketshezi oluzosiza ukuguquguquka, okunciphisa kakhulu ukulahlekelwa ukushisa noma ukuzuza okuvela endaweni.
3. Imisebe:
Ukushisa kungadluliselwa futhi ngamaza kagesi abizwa ngokuthi imisebe.Nakuba ukumbozwa okukhanyayo ezindongeni zangaphakathi zeflask kunciphisa imisebe yokushisa, i-vacuum ngokwayo isebenza njengesithiyo esihle kakhulu ngokumelene nalolu hlobo lokudlulisa ukushisa.
Ekuphetheni:
I-thermos iyingcweti yobunjiniyela, isebenzisa izimiso zokudlulisa ukushisa ukuze inikeze ukufakwa okuthembekile.Ngokuhlanganisa izakhiwo zokuvikela zegebe levacuum nezinto ezinciphisa ukuqhutshwa, ukuguquguquka kanye nemisebe, lawa maflask aqinisekisa ukuthi isiphuzo sakho osithandayo sihlala ezingeni lokushisa olifunayo amahora amaningi ekugcineni.Ngakho-ke ngesikhathi esilandelayo lapho ujabulela inkomishi yekhofi eshisayo noma itiye eliqhwa eliqabulayo elivela ku-thermos, bheka isayensi eyinkimbinkimbi yokuligcina ngendlela othanda ngayo.
