Kodi shelufu ya mufiriji ya zakumwa imatha kunyamula katundu wotani?

Mu malo amalonda, mafiriji a zakumwa ndi zida zofunika kwambiri zosungira ndi kuwonetsa zakumwa zosiyanasiyana. Monga gawo lofunikira la mafiriji, mphamvu ya shelufu yonyamula katundu imagwirizana mwachindunji ndi magwiridwe antchito ndi chitetezo cha kugwiritsa ntchito firiji.

Kuchokera pakuwona makulidwe, makulidwe a shelufu ndi chinthu chofunikira kwambiri chomwe chimakhudza mphamvu yake yonyamula katundu. Kawirikawiri, makulidwe a mapepala achitsulo omwe amagwiritsidwa ntchito popangira mashelufu oziziritsira zakumwa amakhala pakati pa 1.0 mpaka 2.0 millimeters. Pali ubale wabwino pakati pa makulidwe a chitsulocho ndi mphamvu yake yonyamula katundu; pepala lokhuthala limatanthauza kukana kwambiri kupindika ndi kusintha. Pamene makulidwe a shelufu afika 1.5 millimeters kapena kuposerapo, amatha kuchepetsa bwino kupindika komwe kumachitika chifukwa cha mphamvu yokoka pamene ali ndi kulemera kwina kwa zakumwa, zomwe zimapangitsa kuti zikhale zolimba ponyamula katundu. Mwachitsanzo, poika mabotolo ambiri akuluakulu a zakumwa zokhala ndi carbonated, shelufu yokhuthala imatha kukhala yolimba popanda kuzama kapena kusintha koonekeratu, motero kuonetsetsa kuti zakumwa zikusungidwa bwino komanso kuwonetsedwa bwino.

Ponena za zinthu, mashelufu osungira zakumwa nthawi zambiri amapangidwa ndi chitsulo chosapanga dzimbiri kapena chitsulo chapamwamba chozizira. Chitsulo chosapanga dzimbiri chili ndi mphamvu yabwino kwambiri, kukana dzimbiri, komanso kulimba. Sichimangopirira kupsinjika kwakukulu komanso chimagwiritsidwa ntchito kwa nthawi yayitali mufiriji yopanda dzimbiri popanda dzimbiri kapena kuwonongeka, kuonetsetsa kuti kapangidwe ka shelufuyo kakhazikika ndipo motero kumawonjezera mphamvu yonyamula katundu. Pambuyo pokonza shelufu yoziziritsa, chitsulo chozizira chimakhala ndi kuchuluka kwa zinthu ndi kuuma, ndipo mphamvu zake zimawonjezekanso kwambiri, zomwe zingaperekenso magwiridwe antchito abwino onyamula katundu pashelufu. Potengera shelufu yachitsulo chosapanga dzimbiri mwachitsanzo, mphamvu zake zimapangitsa kuti igwire mosavuta katundu wa shelufu yonse ya zakumwa zam'chitini popanda kuwonongeka kwa shelufu chifukwa cha mphamvu zosakwanira za zinthuzo.

Poganizira kukula kwake, miyeso ya shelufu, kuphatikizapo kutalika, m'lifupi, ndi kutalika, imagwirizana kwambiri ndi mphamvu yake yonyamula katundu. Shelufu yayikulu imakhala ndi malo akuluakulu onyamula mphamvu kuti igwirizane ndi kapangidwe kake. Pamene kutalika ndi m'lifupi mwa shelufu ndi zazikulu, ngati zapangidwa moyenera, kulemera komwe kumagawidwa pa shelufu kumatha kusamutsidwa mofanana ku chimango chonse cha firiji, zomwe zimapangitsa kuti inyamule zinthu zambiri. Mwachitsanzo, mashelufu a mafiriji akuluakulu a zakumwa amatha kukhala opitirira mita imodzi m'litali ndi masentimita makumi angapo m'lifupi. Miyeso yotereyi imawalola kusunga mabotolo ambiri kapena mazana a zakumwa zosiyanasiyana, zomwe zimakwaniritsa zosowa za malo ogulitsira kuti asungire zakumwa zambiri. Nthawi yomweyo, kapangidwe ka kutalika kwa shelufu kumakhudzanso mphamvu yake yonyamula katundu; kutalika koyenera kumatha kutsimikizira mphamvu ya shelufuyo kumbali yoyima, ndikupititsa patsogolo mphamvu yonse yonyamula katundu.

Kuwonjezera pa zinthu zomwe zili pamwambapa, kapangidwe ka shelufu sikuyenera kunyalanyazidwa. Kapangidwe koyenera, monga kukonzedwa kwa nthiti zolimbitsa ndi kugawa kwa malo othandizira, kungathandize kwambiri kuti shelufuyo igwire bwino ntchito. Nthiti zolimbitsa zimatha kufalitsa kulemera bwino ndikuchepetsa kusintha kwa shelufu; malo othandizira omwe amagawidwa mofanana angapangitse mphamvu pa shelufu kukhala yolinganizika bwino ndikupewa kuchulukira kwa malo.

Mwachidule, mphamvu ya mashelufu osungira zakumwa zoziziritsa kukhosi ndi zotsatira za zinthu zosiyanasiyana monga makulidwe, zipangizo, kukula, ndi kapangidwe kake. Kawirikawiri, mashelufu osungira zakumwa zapamwamba, okhala ndi makulidwe oyenera (1.5 millimeters kapena kuposerapo), opangidwa ndi chitsulo chosapanga dzimbiri kapena chitsulo chozizira kwambiri, komanso okhala ndi kukula koyenera komanso kapangidwe kake, amatha kukhala ndi mphamvu yonyamula katundu yokwana makilogalamu makumi angapo. Amatha kukwaniritsa zosowa za malo ogulitsa kuti asungire ndikuwonetsa zakumwa zosiyanasiyana, kupereka chitsimikizo champhamvu chosungira bwino komanso kuwonetsa zakumwa moyenera.
