Chikwama cha firiji kapena, monga momwe imatchedwanso, thumba lachikopa ndi chinthu chofunikira m'banja lomwe limatsogolera moyo wokhutira. Ngati mumakonda kuyenda kuti muzitha kusangalala ndi chilengedwe, oyendayenda amayenda pa galimoto yanu kapena nthawi zambiri mumayenda ulendo wautali mu sitima, ndiye simungathe kuchita popanda thumba la firiji! Thumba la thermo limapangitsa kukhalabe ndi mphamvu ya kutentha kuti kusungidwa kwa mankhwala kukhale ozizira, ozizira kapena mawonekedwe otentha.
Kusankha thumba la firiji
Ogula angathe kudziwa momwe angasankhire thumba la firiji, ndizofunikira zotani posankha.
Miyeso ya gaga
Mitambo ya thermosets yaying'ono yokonzera masangweji pang'ono kapena mitsuko ya zakumwa, kulemera kwake ndi 400 g Mu thumbali ndibwino kuti mupange chakudya cham'mawa cha mwana kapena chakudya cha mnzanuyo. Pafupifupi thumba la isothermal limakulolani kutenga 10 - 15 makilogalamu. Matumba amenewa amadzala m'manja, pamapewa kapena kumbuyo kwa mapewa. Manja kapena mabala aakulu amakhala opangidwa ndi zofewa zawo.
Matumba akuluakulu omwe amatha kufika 30 mpaka 35 makilogalamu nthawi zambiri amanyamula mawilo.
Nthawi yosungirako katundu wa thumba
Ngati mukufuna kugula zinthu zofunika kwambiri mnyumba, mukufuna kudziwa kuti thumba lozizira limakhala lotentha nthawi yaitali bwanji?
Nthaŵi yosunga ulamuliro wa kutentha imadalira makamaka kukula kwa mankhwala. Sungani zinthu mu kutentha kochepa popanda batri kungakhale maola 3 mpaka 4, mu matumba ang'onoang'ono ndi nthawi yosungirako batri ikuwonjezeka maola 7 mpaka 13. Mitundu yayikulu ya kutentha imatsimikiziridwa kuti ikhalebe yofuna kutentha pa tsiku.
Zipangizo zomwe matumba omwe amawotcha firiji amapangidwa
Thermosets amapangidwa kuchokera ku nsalu zotchinga kwambiri (polyester, nylon) kapena ma polymondi olimba. Monga kutsekemera kwa matenthedwe, zipangizo zamakono zimagwiritsidwa ntchito: foam polyethylene kapena thovu polyurethane. Kugwiritsa ntchito zipangizozi kumapereka chisamaliro chosavuta komanso chaukhondo kwa mankhwalawa. Iwo ndi osavuta kupukutira, kusamba m'manja. Kuonjezerapo, pokhapokha kutayika kwa madzi aliwonse mu thumba, chinyezi sichidzatsanulira. Thumba la thermo lili ndi mafupa opangidwa ndi mphuno wambiri, yomwe imathandiza kuti zisunge kutentha, komanso kuti zisasokoneze katunduyo.
Chivomerezo pa botolo botmos
Onetsetsani kuti muwone pamene mukugula thumba ngati liri ndi chitsimikiziro. Kawirikawiri mawuwo ndi ochepa - miyezi itatu, koma botolo la thermos ndilolondola kwa zaka zingapo.
Moyo wautumiki wa thumba ndi kugwiritsa ntchito mosamala ndi zaka zisanu ndi zisanu ndi ziwiri.
Mfundo ya thumba la firiji
Monga chinthu chozizira pa thumba la firiji, ayezi owuma ndi ozizira ozizira amagwiritsidwa ntchito . Mabatire amapangidwa ngati matumba kapena mabatire apulasitiki, mkati mwawo ndi mankhwala a saline ndi zowonjezera zowonjezera zomwe zimathandiza kukhalabe ndi mphamvu yofunikira ya kutentha. Batire imayikidwa maola 7 mufiriji, ndipo pambuyo pake iyo imayikidwa mu thumba la thermo.
Ngati mukufuna kusunga chakudya chokwanira mu thumba lanu, simukuyenera kuika mabatire ozizira.
Kodi mungagwiritse ntchito bwanji thumba la firiji?
Musanayambe kusungira katundu mu thumba, choyamba, amaika mabatire ozizira. Tiyambe-timayika nyama, nsomba, ndiwo zamasamba ndi zipatso mu matumba a cellophane kapena mapulasitiki. Mwa njira, matumba ena omwe amagulitsidwa muyikidwa amakhala ndi zida zapadera.
Posachedwapa, zikwama zamagetsi zimagwiritsidwanso ntchito pa tsiku ndi tsiku, komabe ndi zipangizo zamakono za magulu ena ogwira ntchito: zikwama zimagwiritsidwa ntchito popereka zakudya zowonongeka, ogwira ntchito zachipatala chifukwa chokhala ndi katemera, zipangizo zoyesera, ndi zina zotero.
