Kusukela ngo-2017, izinkomishi ezingasindi zaqala ukubonakala emakethe yenkomishi yamanzi, futhi ngemva nje kwalokho, izinkomishi zokulinganisa ezikhanyayo zaqala ukubonakala emakethe. Iyini inkomishi engasindi? Iyini inkomishi yokulinganisa ekhanyayo kakhulu?
Uma sithatha inkomishi ye-thermos yensimbi engagqwali engu-500 ml njengesibonelo, isisindo esilinganiselwe esikhiqizwa ngokwezinqubo zendabuko siphakathi kuka-220g no-240g. Uma isakhiwo sihlala sifana nesivalo siyafana, isisindo senkomishi engasindi siphakathi kuka-170g no-150g. Isisindo senkomishi engasindi sizoba phakathi kuka-100g-120g.
Zenziwa kanjani izinkomishi zokulinganisa ezingasindi neze-ultra-light?
Njengamanje, izinqubo ezithathwe izinkampani ezihlukahlukene zifana ngokuyisisekelo, okungukuthi, umzimba wendebe onesisindo esivamile ngokwenqubo yendabuko ucutshungulwa futhi ngenqubo yokunciphisa. Ngokuya ngesakhiwo somkhiqizo, ukujiya okuhlukile kokuncipha kungafinyelelwa. Ngemva kokukhipha izinto ezisikiwe ezijikelezayo ngaphakathi kobubanzi obuvunyelwe inqubo, umzimba wenkomishi okhona uzokuba lula ngokwemvelo.
Hhayi-ke, senze okunye ukuduma kwezinkomishi ezingasindi esikhathini esidlule. Njengamanje, siphendula umbuzo wokuthi kungani ukushuba kodonga lwenkomishi ye-thermos kuncane kakhulu, kuba ngcono umphumela wokufakelwa. Izihloko eziningi ezedlule zikhulume ngenqubo yokushisa okushisayo kwezinkomishi ze-thermos. Ngakho-ke njengoba ukufakwa kwe-thermal kufinyelelwa ngenqubo ye-vacuum, kuhlobene kanjani nokuqina kodonga lwenkomishi? Lapho kusetshenziswa inqubo efanayo yokukhiqiza kanye nemingcele yezobuchwepheshe yokushanela ifana ncamashi, ubukhulu bodonga lwenkomishi ye-thermos buzohambisa ukushisa ngokushesha, futhi into ewudonga ewugqinsi izoba nevolumu enkulu yokuxhumana emunca ukushisa, ngakho-ke ukushiswa kube ngokushesha. Ivolumu yokuxhumana emunca ukushisa yenkomishi ye-thermos enezindonga ezincane izoba yincane uma kuqhathaniswa, ngakho-ke ukuchithwa kokushisa kuzohamba kancane.
Kodwa lo mbuzo uhlobene. Akunakushiwo ukuthi indebe ye-thermos enodonga oluncane kufanele ibe yi-insulating kakhulu. Izinga lomthelela wokufakelwa lincike kakhulu kwikhwalithi yobuchwepheshe bokukhiqiza kanye namazinga okulawulwa kwenqubo yokukhiqiza. Ngesikhathi esifanayo, akuzona zonke izinkomishi zamanzi ezifanele inqubo yokunciphisa i-spin. Kukhona nemikhiqizo enamandla amakhulu njengamabhodlela e-thermos angu-1.5-litre. Ngisho noma isakhiwo sabo singahlangabezana nokukhiqizwa kwenqubo yokunciphisa i-spin-thinning, akunconywa ukusebenzisa ubuchwepheshe be-spin-thin. Ubuchwepheshe be-spin-thin abunconywa. Ukunciphisa ukujiya kodonga nakho kudinga ukuba phakathi kwebanga elifanele.
Uma ukujiya kodonga kuncane kakhulu, amandla aqinile engamelana nawo aphansi kunamandla okumunca akhiqizwa ukucwenga, futhi umphumela omncane uzoba ukuwohloka kodonga lwenkomishi. Ezimweni ezimbi kakhulu, udonga lwangaphakathi nodonga lwangaphandle luzoshayisana, ukuze umphumela wokulondoloza ukushisa ungafinyelelwa. Amandla okumunca akhiqizwa inkomishi ye-thermos enomthamo omkhulu noma inkomishi ye-thermos ngemva kokukhishwa makhulu kunalawo endebe yamanzi emthamo omncane. Udonga lwenkomishi yamanzi enamandla amancane olungafinyelela uzinzo ngemva kokuncishiswa luzokhubaza eketelani elinomthamo omkhulu.
