Thermos ngezandla zabo. Indlela yokwenza iplagi ukuze thermos?

Ukuze namphi na umhambi, Umlobi kunye umntu onamathela yokuphila asebenzayo, a thermos nezwi ezinye endaweni yazo. Ingakumbi imfuno kuba waziva ngexesha yabanda lonyaka, xa abantu bathenge iziselo ezishushu ukukhululeka kuphela. Umntu uza ngobuchule kwaye kubathwala naye kwangaphambili. Kodwa, oku kufuna ukuba isikhongozeli kunye conductivity thermal ephantsi, ukuthenga maxa wambi akukho ithuba nje.

Indlela kuphela phandle - ukwenza thermos ngezandla zabo. Indlela ukukwenza oko? Eli nqaku liza kukuxelela.

device capacitance

Abantu abaninzi bayawazi Dewar. Kwaba kwimigaqo yakhe yasekwa thermos: kwiziphathi umthamo ezinkulu ezibekwe, ezincinane ububanzi, yaye phakathi kwabo ngomatshini kudala into elapha, kakhulu ukunciphisa conductivity thermal.

Kakade ke, kwikhaya kwenza oko akusebenzi, ngoko imveliso ogqityiweyo iya kuba nempumelelo kangako. Kulo mzekelo, i-bume ebonakalayo luzakubuyisela ngefoyile, kunye thermos ngezandla zabo (indlela yokwenza isikhongozeli yokugcina ulwelo, bona ngezantsi) ziya kancinane kuphela lubi uthenge.

Indlela elula avelise ezinqwenelekayo ngaphandle iibhotile zeplastiki.

Imiyalelo ngokudala thermos

Ukuba nguye nabani na azive ogama, uya kudinga oku kulandelayo:

• iibhotile ezimbini, umqulu 500 ml kunye 1500 ml, ngokulandelelana;
• izikere ezibukhali;
• Zokubhala imela;
• ngefoyile ye-aluminiyam;
• amaphepha aliqela ephepheni;
• tape ububanzi.

Kwaye ngoku khangela indlela yokwenza i thermos ngezandla zabo - ukuba ukwenza njani, umzekelo, ukususela imigqomo yeplastiki:

1. Zezindlu elizayo kunqunyulwa emazantsi kunye entanyeni kwiindawo eziliqela liqatywe nkqo kwi kwinxalenye engentla ebhotileni. Oku kufuneka ukuba kuqinisekiswe ukuba izikhongozeli ezincinane ukulingana snugly kungena emngxunyeni.
2. Kushunyayelwe ibhotile (iselwa) ngefoyile ye urhangqo, kwicala ziyabuyiseleka ekufuneka ahlale ngaphakathi.
3. Kwakhona uyisongele amaphepha ndaba kwizingxobo ifakiwe umzimba ixinene kakhulu, ngokukhethekayo ne kufanelekile uphazamiseko.
4. Faka ibhotile ezincinane kwibhokisi enkulu. Buyisela ezantsi kwe kusikwa ndawo ukwenzela ukuba iinxalenye idlulela. Kuba ukuthembeka omkhulu seal 3-4 kunokudala tape ngokubanzi.
5. Housing urhangqo ne ngefoyile ye kunye ngcina tape - oku kuya kunceda kancinci zokunciphisa conductivity thermal.

Imiqathango yosetyenziso

Yenza thermos yeplastiki ngezandla zabo (indlela yokuyenza, siye ichazwe kwinqaku) kulula. Kodwa yena, Kakade, ngakumbi ngqo. Xa umsebenzi kuyimfuneko ukuba athathe ingqalelo enye isithintelo elula: Ungaze ugalele amanzi abilayo kwi itanki epholileyo.

eziyingozi amaqondo aphakamileyo ukuze umbandela, ukuba mninzi ayonelanga. Kule meko izikhongozeli baye deformation enkulu, yaye kwiimeko ezithile nokuba bakwazi ukwahlukana nabo. Ngaloo ndlela, a thermos ndiyizalise ulwelo podostyvshuyu.

Ukuze uphephe oku, njengoko ibhalbhu kuyimfuneko ukuba usebenzisa ibhotile yeglasi. Oku uyakwazi ukumelana amaqondo aphezulu kwaye conductivity thermal ephantsi.

Ukongeza, nangona iplasitiki ethambileyo akukho kwaphulwa; umyeke yaye ufuna - izinto ukuze kugqabhuka.

Indlela ukwenza thermos ngezandla zabo ingqayi

Kuba abathandi ukuhamba ebusika, olu khetho okufanelekileyo entle nje. Made kwisikhongozeli thermos kuzakugcina ukutya okuqinileyo eshushu ixesha iiyure eziliqela. Noko ke, yokugcina ulwelo olo khetho kungcono ukuba ukuyisebenzisa.

Ukwenza ezi izitya zifuna:

• ingqayi yeplastiki enesiciko;
• lyu elana;
• tape ebanzi;
• tikelo.

Inyathelo ngu step guide:

1. Sika uxande ekwambathiseni, ubukhulu ekunene, ukuba azisongele kubo esinqeni iibhanki. Shiya isibonelelo encinane, wabeka ngohlangothi ukudlulela laphu. indawo ekhuselekileyo tape compound.
2. Beka amandla ngenxa yentsalela ka lyu, ukuchaza elinye kuye. Le isangqa kubangele ukukrola qhoboshela asemacaleni thermos elizayo kunye enamathelayo.
3. Iintshukumo efanayo makwenziwe isiciko. Kuba ukuthembeka olungcono kudibana kufuneka silungise le tape.

Yiloo nto - a thermos ukulungele.

Ukuveliswa caps

Ngamanye amaxesha, xa yindlela lweenkobe akaphumeleli, umbuzo uvela kubantu: ukuplaga indlela thermos ngezandla zabo? Oku kuya kufuna:

• zabase;
• ngefoyile ye-aluminiyam;
• amagwebu;
• film ukutya.

Indlela elula ukubabuyisela ebomini kwiplagi endala. Kuyinto elula ngokwaneleyo ukuba ezikucaphukisa kakhulu, ska kwindawo vice, yaye ngaloo ndlela ukugcina olupholisa epheleleyo. Emva koko mpahla kufuneka kukugubungela ngefoyile ye - oku kuya wowusindisa lowo ekutshatyalalisweni phantsi kwempembelelo amaqondo obushushu aphezulu.

Kwaye ukuze wenze cap esitsha (ekukhethwa ukuba phambi kokuba enze thermos ngezandla zabo), kufuneka isiqwenga njengogwebu. Kulo wagawulwa isiqalelo imilo olufunayo kunye nobukhulu, nto leyo ligutyungelwe bambelelani umboniso ukuthintela ukuchitheka kulwelo.

Ukuba oku utyhala thermos isivalo, ngoko kuya kuba ngokwaneleyo ukuba Babesinqinda ngokusebenzisa ngenaliti evela kwisirinji. Kuyacetyiswa ukuba wenze umgqobho embindini, kungenjalo yeplagi kungenziwa zikhubazekile.

isiphelo

Ukwakha izakhono zabo zokugcina amanzi kunye nokutya, njengoko kanti, kakhulu nje. Kakade ke, kufuneka singaze silibale ngayo ezingasebenziseki kakuhle xa kuthelekiswa namanye lowu kwaye imali ungangxameli bekufunwa kunokwenzeka.

Kodwa elinye ithuba thermos ezinzima ezifana gqolo: ukuba akukho nanceba kuwabhuqa, ngenxa yokuba kuveliswe kuthatha ixesha elincinane, kwaye indleko amandla luzobe zero.
