Uyini umehluko phakathi kobuningi obubonakalayo kanye nobuningi bezinto zokushisa ezisetshenziswa ekushiseni?

Ubuningi obubonakalayo bubhekisela esilinganisweni sobuningi bento ethile nobuningi bayo obubonakalayo. Ubuningi obubonakalayo buyivolumu yangempela kanye nobuningi bembobo evaliwe. Bubhekisela esilinganisweni sesikhala esithathwe yinto ngaphansi kwesenzo samandla angaphandle nobunzima bento, evame ukuvezwa ngamakhilogremu ngemitha eyi-cubic (kg/m³). Bungabonisa ubuningi, ubulukhuni, ukunwebeka kanye nezinye izakhiwo zento. Ezintweni ezinezimo ezijwayelekile, ubukhulu bungalinganiswa ngqo; ezintweni ezinezimo ezingavamile, amambobo angavalwa ngokuvalwa kwe-wax, bese ubukhulu bungalinganiswa ngokuphuma kwamanzi. Ubuningi obubonakalayo buvame ukulinganiswa esimweni semvelo sento, okungukuthi, isimo esomile esigcinwe emoyeni isikhathi eside. ‌Ezintweni zerabha nepulasitiki ezifakwe igwebu, isilinganiso samabhamuza avaliwe ezingxenyeni zerabha nepulasitiki siyahlukahluka, futhi kukhona ububanzi bobuningi obunokushisa okuphansi kakhulu.

I-porosity ephezulu ingavikela ngempumelelo; kodwa ukuminyana okuphansi kakhulu kungaholela kalula ekuguqukeni nasekuqhekekeni. Ngesikhathi esifanayo, amandla okucindezela ayanda ngokwanda kokuminyana, okuqinisekisa ukuzinza kwesikhathi eside kwezinto. Ngokuphathelene nokuqhuba ukushisa, lapho ukuminyana kuncane, ukuguquguquka kokushisa kuyancipha futhi ukufudumala kungcono; kodwa uma ukuminyana kuphakeme kakhulu, ukudluliselwa kokushisa kwangaphakathi kuyanda futhi umphumela wokuvimbela ukushisa uyancipha. Ngakho-ke, lapho ukhetha izinto zokuvimbela ukushisa, kubalulekile ukucabangela ngokuphelele ukuminyana kwazo okubonakalayo ukuqinisekisa ukuthi izakhiwo ezahlukene zilinganiselwe ukuhlangabezana nezidingo zezimo ezahlukene zokusetshenziswa.
Ubuningi bezinto bubhekisela ekubuneni kwezinto ngokwazo, okungukuthi, isilinganiso sesikhala esithathwe yinto nobukhulu bayo. Ezintweni zokushisa, ngokuvamile kubhekisela esilinganisweni somoya wangaphakathi kanye nobuningi bangempela ngevolumu ngayinye, okuvezwa ngamakhilogremu ngemitha eyi-cubic (kg/m³). Ngokufana nobuningi obubonakalayo, ubuningi bezinto bungenye yemingcele ebalulekile yokuhlola ukusebenza kwezinto zokushisa, okuvame ukukhombisa isisindo, ukumuncwa kwamanzi, ukufudumala kanye nezinye izici zezinto.

Ngakho-ke, nakuba kokubili ukuminyana okubonakalayo kanye nokuminyana okukhulu kubonisa ukuminyana kanye nokuvuleka kwezinto zokushisa, kunemehluko ethile esobala:
1. Izincazelo ezahlukene
Ubuningi obubonakalayo bezinto zokushisa buhlola kakhulu izakhiwo zezinto ezifana nokuvuleka kanye nokuqina, futhi bungabonisa ubudlelwano obulinganayo phakathi komoya kanye nobunzima bangempela ngaphakathi kwezinto.
Ubuningi bezinto ezivikela ukushisa bubhekisela ekuqineni kwezinto zokuvikela ukushisa uqobo, futhi abubandakanyi noma yiziphi izakhiwo zesakhiwo sangaphakathi.
2. Izindlela ezahlukene zokubala
Ubuningi obubonakalayo bezinto zokuvikela umswakama buvame ukubalwa ngokulinganisa isisindo kanye nobuningi besampula, kuyilapho ubuningi bubalwa ngokulinganisa isisindo sesampula yezinto ezibonakalayo zobuningi obaziwayo.
3. Kungase kube namaphutha
Njengoba ukubalwa kobuningi obubonakalayo bezinto zokufaka umswakama kusekelwe kuvolumu ethathwe yisampula ecindezelwe, akukwazi ukumelela kahle isakhiwo sonke sezinto. Ngesikhathi esifanayo, uma kunezimbobo noma izinto zangaphandle ngaphakathi kwezinto, ukubalwa kobuningi obubonakalayo nakho kungaba namaphutha. Ubuningi bezinto abunazo lezi zinkinga futhi bungabonisa ngokunembile ubuningi kanye nesisindo sezinto zokufaka umswakama.

Indlela yokulinganisa
Indlela Yokufuduka: Kwezinto ezinezimo ezijwayelekile, ivolumu ingalinganiswa ngqo; ezintweni ezinezimo ezingavamile, ama-pores angavalwa ngendlela yokuvala i-wax, bese ivolumu ingalinganiswa ngendlela yokuhambisa.
Indlela ye-Pycnometer: Kwezinye izinto, njengezinto zekhabhoni, indlela ye-pycnometer ingasetshenziswa, nge-toluene noma i-n-butanol njengesixazululo esijwayelekile sokulinganisa, noma indlela yokuhambisa igesi ephakathi ingasetshenziswa ukugcwalisa ama-micropores nge-helium kuze kube yilapho ingasakwazi ukumuncwa.

Izindawo zokufaka isicelo
Ubuningi obubonakalayo bunezinhlobo eziningi zokusetshenziswa kwisayensi yezinto zokwakha. Isibonelo, emikhiqizweni yerabha ye-foam eguquguqukayo kanye ne-plastic insulation, inhloso eyinhloko yokuhlolwa kobuningi obubonakalayo ukuhlola ukusebenza kobuningi bayo nokuqinisekisa ukuthi ukuqina kwayo kokushisa kanye nezakhiwo zayo zemishini kuyahlangabezana nezindinganiso. Ngaphezu kwalokho, ubuningi obubonakalayo busetshenziselwa futhi ukuhlola izakhiwo ezibonakalayo zezinto zokwakha kanye nokusebenza kwezinto zokusebenza kwizicelo zobunjiniyela.
Uma ubuningi bukhula futhi izingxenye zerabha nepulasitiki zikhula, amandla ezinto ezibonakalayo kanye ne-wet rent factor kunganda, kodwa ukuguquguquka kokushisa kuzokhula ngokungenakugwenywa futhi ukusebenza kokushisa kuzowohloka. I-Kingflex ithola iphuzu elifanele kakhulu lokulinganisela ebudlelwaneni obuvimbelayo phakathi kokuguquguquka kokushisa okuphansi, i-wet rent factor ephezulu, ukuqina okubonakalayo okufanele kakhulu kanye namandla okudabuka, okungukuthi, ukuqina okufanelekile.
