Ukudangala okusobala kubhekisele ekulinganiselweni kwesisindo sezinto ezibonakalayo kwivolumu yalo ebonakalayo. Ivolumu ebonakalayo yivolumu yangempela kanye nevolumu ye-pore evaliwe. Kusho isilinganiso sesikhala esihlalwa yinto engaphansi kwesenzo samandla angaphandle esisindo salezi zinto ezibonakalayo, evame ukuvezwa ngamakhilogremu ngamamitha ayi-cubic (kg / m³). Kungabonisa i-poriality, ubulukhuni, ubuqili nezinye izakhiwo zezinto ezibonakalayo. Ngezinto zokwakha ezinobukhulu obujwayelekile, ivolumu ingalinganiswa ngqo; Ukuze uthole izinto zokwakha ezingekho emthethweni, ama-pores angavalwa ngokubekwa uphawu kwe-wax, bese ivolumu ingalinganiswa ngamatshe. Ukuqina okusobala kuvame ukukala ngesimo semvelo salokho okuqukethwe, okungukuthi, isimo esomile esigcinwe emoyeni isikhathi eside. Ngezinto zokwenziwa zenjoloba ze-Foed nepulasitiki, isilinganiso sama-bubble avaliwe-iseli kwizakhi zenjoloba nezopulasitiki ziyahlukahluka, futhi kunobubanzi obukhulu obunobunzima obuphansi kakhulu.
I-porolity ephezulu ingafaka umzimba ngempumelelo; Kepha ukuqina okuphansi kakhulu kungaholela kalula ekuguqukeni nasekuqhekekeni. Ngasikhathi sinye, amandla okucindezela anda ngokwanda kobukhulu, aqinisekise ukuqina kwesikhathi eside kwezinto ezibonakalayo. Ngokuya nge-thermal activity, incane ukuqina, ukwehlisa ukuthuthuka okushisayo kanye nokufakwa okungcono kokufakelwa okushisayo; Kepha uma ubuningi buphezulu kakhulu, ukuhanjiswa kokushisa kwangaphakathi kukhuphuka futhi umphumela wokufakelwa okushisayo uyancipha. Ngakho-ke, lapho ukhetha izinto zokufakelwa okushisayo, kuyadingeka ukuze ubheke ngokugcwele ubuntu babo bokuqinisekisa ukuthi izakhiwo ezahlukahlukene zilinganiselwe ukuze zihlangabezane nezidingo zezidingo ezihlukile zokusebenzisa izimo.
Ubuningi obuningi bubhekisela ebuntwini bezinto ezibonakalayo uqobo, okungukuthi, isilinganiso sesikhala esihlalwe yinto esisindo sayo. Ezintweni zokufaka okushisayo, kuvame ukubhekisela ku-rationio yomoya wangaphakathi we-pore air kanye ne-mass yangempela yevolumu ngayinye, kuvezwe ngamakhilogremumitha ngayinye imitha ye-cubic (kg / m³). Ifana ne-Afflent Fensity, ubuningi obuningi bungomunye wamapharamitha abalulekile wokuhlola ukusebenza kwezinto zokufaka okushisayo, ezivame ukukhombisa isisindo, ukumuncwa kwamanzi, ukufakwa okushisayo kanye nezinye izici zezinto ezibonakalayo.
Ngakho-ke, yize zombili izinqumo ezibonakalayo nobuningi obuningi bekhombisa ukuqina kanye nokuqina kwezinto zokwehlukanisa okushisayo, zinomehluko osobala:
1. Izincazelo ezihlukile
Ubukhulu obubonakalayo bezinto zokufakwa kwezinsiki ezishisayo buhlaziya ikakhulukazi izakhiwo zezinto ezinjenge-porosity kanye nokuqina, futhi ungakhombisa ubudlelwane obulinganayo phakathi komoya kanye nesisindo sangempela ngaphakathi kokuqukethwe.
Ubuningi obuningi bubhekisela ebuntwini be-density yezinto ezibonakalayo uqobo, futhi akubandakanyi noma yiziphi izakhiwo zesakhiwo sangaphakathi.
2. Izindlela ezihlukile zokubala
Ubukhulu obubonakalayo bokufakwa kwezinto zokufakelwa buvame ukubalwa ngokulinganisa isisindo kanye nevolumu yesampula, kanti ubuningi obuningi bubalwa ngokulinganisa isisindo sesampula yezinto ezibonakalayo zevolumu eyaziwayo.
3. Kungahle kube namaphutha
Kusukela ekubalweni kobuningi obubonakalayo be-infation material bususelwa kwivolumu ethathwe isampula elicindezelwe, alikwazi ukumela kahle ukwakheka okuphelele kwezinto. Ngasikhathi sinye, lapho kunemithambo noma khona noma ngabe kungenzeka kube khona izinto ezibonakalayo, ukubalwa kobuningi obubonakalayo kungenzeka kube namaphutha. Ubuningi obuningi abanazo lezi zinkinga futhi bungakhombisa ukunemba okunembile nesisindo sendwangu yokufakelwa.
Indlela yokulinganisa
Indlela yokusuka ekuchithweni: ngezinto zokwakha ezinobukhulu obujwayelekile, ivolumu ingalinganiswa ngqo; Okwezinto zokwakha ezinobukhulu obungajwayelekile, ama-pores angavalwa nge-wax searing indlela, bese ivolumu ingalinganiswa ngendlela yokufuduka.
Indlela ye-Pycnometer: kwezinye izinto zokwakha, njengezinto zokwakha zekhabhoni, ingasetshenziswa i-Pycnometer, nge-toluene noma i-n-butanol njengesixazululo esijwayelekile sokulinganisa, noma indlela yokufudumala ephakathi nendawo ingasetshenziswa ukugcwalisa ama-micropores aze afike Cishe ayisasekho ama-adsorbed.
Izindawo zohlelo lokusebenza
Ukudambisa okusobala kunezinhlobonhlobo zezicelo ku-Material Science. Isibonelo, kumikhiqizo eguqukayo ye-Foam ye-Foam kanye nePulasitiki, inhloso eyinhloko yohlolo lwabantu ababonakalayo ukucubungula ukusebenza kwalo kwe-density futhi baqinisekise ukuthi ukufakwa kwayo okushisayo kanye nezindawo zemishini zihlangabezana namazinga. Ngaphezu kwalokho, ukuqina okusobala kusetshenziselwa futhi ukuhlola izakhiwo ezibonakalayo zezinto zokwakha kanye nokusebenza kwezinto zokwenziwa kwezicelo zobunjiniyela.
Uma ukuncipha kukhuphuka kanye nerabha kanye nezakhi zepulasitiki ziyenyuka, amandla abonakalayo kanye nerenti ethambisayo kungakhuphuka, kepha ukuthuthuka okushisayo kuzokwanda nakanjani futhi ukusebenza kwe-insulation okushisayo kuzokwehla. I-KingFlex ithola indawo esetshenziswayo ephelele ebudlelwaneni obunqunyelwe phakathi kokuvuselelwa okuphansi okuphansi, isici sokuqasha esiphakeme esiphakeme, ukuqina okusobala okusobala kanye namandla ezilile.
