Apparent density ireshiyo yehuremu hwechinhu kusvika kuvhoriyamu yacho inooneka. Vhoriyamu inooneka ndiyo vhoriyamu chaiyo pamwe nekuvharwa kwepore volume. Inoreva chiyero chenzvimbo inogarwa nechinhu chiri pasi pechiito chesimba rekunze kune kuwanda kwezvinhu, kazhinji kuratidzwa mumakirogiramu pa cubic mita (kg/m³). Inogona kuratidza porosity, kuoma, elasticity uye zvimwe zvinhu zvezvinhu. Kune zvigadzirwa zvine maumbirwo enguva dzose, vhoriyamu inogona kuyerwa zvakananga; pamidziyo ine maumbirwo asina kurongeka, maburi anogona kuvharwa nenamo yakavharwa, uye ipapo vhoriyamu inogona kuyerwa nekuyerera. Iyo inooneka density inowanzoyerwa muchimiro chechisikigo chechinhu, ndiko kuti, iyo yakaoma mamiriro yakachengetwa mumhepo kwenguva yakareba. Zvemafuro erabha uye epurasitiki ekudzivirira zvinhu, chiyero cheakavharika-sero mabhubhu kune rabha uye epurasitiki zvikamu zvinosiyana, uye kune density renji ine yakaderera yekupisa conductivity.
High porosity inogona kunyatsovhara; asi yakanyanya kuderera density inogona kutungamira nyore ku deformation uye kutsemuka. Panguva imwecheteyo, simba rekumanikidza rinowedzera nekuwedzera kwehuwandu, kuve nechokwadi chekugara kwenguva refu kwezvinhu. Mukutaura kwekupisa kwekushisa, kuduku kuduku, kuderera kwekushisa kwekushisa uye zviri nani kupisa kwekushisa; asi kana density yakanyanyisa, kupisa kwemukati kwekushisa kunowedzera uye kupisa kwekushisa kunoderera. Naizvozvo, kana uchisarudza zvinopisa zvekudzivirira zvekushandisa, zvinodikanwa kunyatso funga nezve density yavo kuti ive nechokwadi chekuti zvakasiyana zvivakwa zvakaenzana kuti zvisangane nezvinodiwa zvemashandisirwo akasiyana.
Bulk density (Bulk density) zvinoreva kuwanda kwechinhu pachacho, kureva chiyero chenzvimbo yakagarwa nechinhu kusvika pakukura kwayo. Mumidziyo yekupisa yekupisa, inowanzo reva chiyero chemukati wepore mhepo uye huremu chaihwo pavhoriyamu yeyuniti, inoratidzirwa mumakirogiramu pacubic mita (kg/m³). Zvakafanana nehuremu hunooneka, kuwanda kwehuwandu zvakare ndeimwe yeakakosha ma paramita ekuongorora mashandiro ezvishandiso zvekupisa, izvo zvinowanzo ratidza huremu, kunyura kwemvura, kupisa kwemafuta uye humwe hunhu hwechinhu.
Naizvozvo, kunyangwe zvese zviri zviviri density uye kuwanda kwehuwandu zvichiratidza kuwanda uye porosity yezvinhu zvinopisa zvekudzivirira, zvine mimwe misiyano iri pachena:
1. Zvinoreva zvakasiyana
Iyo inooneka density yezvinhu zvinopisa zvekudzivirira zvinonyanya kuongorora zvimiro zvezvinhu zvakaita seporosity uye elasticity, uye inogona kuratidza hukama hwakaenzana pakati pemhepo nehukuru chaihwo mukati mechinhu.
Bulk density inoreva kuwanda kweiyo insulation material pachayo, uye haisanganisi chero zvimiro zvemukati chimiro.
2. Nzira dzekuverenga dzakasiyana
Iyo inooneka density yemidziyo yekudzivirira inowanzoverengerwa nekuyera huremu uye vhoriyamu yemuenzaniso, nepo kuwanda kwehuwandu huchiverengerwa nekuyera huremu hwesample yechinhu chevhoriyamu inozivikanwa.
3. Panogona kunge paine zvikanganiso
Sezvo kuverengerwa kweiyo inooneka density yechinhu chekudzivirira kwakavakirwa pavhoriyamu inogarwa neyakamanikidzwa sampu, haigone kumiririra iyo yakazara chimiro chechinhu. Panguva imwecheteyo, kana paine cavities kana zvinhu zvekunze mukati mechinhu, kuverenga kweiyo inooneka density kunogonawo kuve nekukanganisa. Bulk density haina matambudziko aya uye inogona kunyatso ratidza huremu uye huremu hwechinhu chekudzivirira.
Chiyero nzira
Displacement nzira: Zvemidziyo ine maumbirwo akajairwa, vhoriyamu inogona kuyerwa zvakananga; pamidziyo ine maumbirwo asina kurongeka, pores anogona kuvharwa newakisi yekuvharisa nzira, uye ipapo vhoriyamu inogona kuyerwa nenzira yekubvisa.
Pycnometer nzira: Kune zvimwe zvinhu, senge kabhoni, iyo pycnometer nzira inogona kushandiswa, ine toluene kana n-butanol seyakajairwa mhinduro yekuyera, kana gasi yepakati nzira yekubvisa inogona kushandiswa kuzadza mamicropores nehelium kusvika yapera. inenge isisiri adsorbed.
Nzvimbo dzekushandisa
Density inooneka ine huwandu hwakasiyana hwekushandisa mune zvesainzi zvezvinhu. Semuyenzaniso, mune inochinjika furo rabha uye epurasitiki yekumisa zvigadzirwa, chinangwa chikuru cheinooneka density bvunzo ndeyekuongorora density yayo kuita uye kuona kuti kupisa kwayo kwekupisa uye zvivakwa zvemuchina zvinosangana nezviyero. Pamusoro pezvo, density inooneka inoshandiswawo kuongorora humiro hwezvinhu zvemidziyo uye kuita kwezvinhu mumainjiniya ekushandisa.
Kana iyo density ikawedzera uye iyo rabha nemidziyo yepurasitiki ichiwedzera, simba rezvinhu uye wet rendi chinhu chinogona kuwedzera, asi iyo yekupisa conductivity inozowedzera kuwedzera uye mashandiro emafuta ekudzivirira anozodzikira. Kingflex inowana yakakwana yakakwana yechiyero chepakati muhukama hwepakati pakati peiyo yakaderera thermal conductivity, iyo yakakwirira yemvura yekurenda chinhu, iyo yakanyanya kufanirwa inooneka density uye kubvarura simba, ndiko kuti, iyo yakakwana density.
