Isihloli Sendawo Ekhethekile YaseLabhorethri Kasimende Blaine

一、 Ukucaciswa

Ngokuvumelana ne-GB/T8074—2008 standard yesifunda sithuthukisa imodeli entsha ye-SZB-9 Auto Ratio tester.Umshini ulawulwa ikhompuyutha, futhi usebenza ngokhiye bokuthinta abathambile, inqubo yokuhlola ephelele yokulawula okuzenzakalelayo.Khumbula ngokuzenzakalelayo i-coefficient, bonisa inani lendawo yesilinganiso ngokuqondile ngemva kokuphela komsebenzi wokuhlola, futhi ingakhumbula ngokuzenzakalela isikhathi sokuhlola.

2.

Ithiyori ye-BET (i-Brunauer, i-Emmett kanye ne-Teller) ivamise ukusetshenziselwa ukuhlola idatha ye-gas adsorption futhi ikhiqize umphumela othize wendawo ovezwa ngamayunithi endawo ngesisindo ngasinye sesampula (m2/g).Le nqubo ibhekiselwa izinhlangano eziningana ezijwayelekile njenge-ISO, USP kanye ne-ASTM.

Le ndlela isetshenziswa kakhulu ezintweni eziningi, kodwa ithembeke kakhulu ezintweni ezinohlobo lwe-II noma uhlobo lwe-IV isotherm enezinga elanele lokusebenzisana phakathi kwegesi ye-adsorbate nengaphezulu.Ngezinto zokwakha ezinezinye izinhlobo ze-isotherm, ithiyori ye-BET ingase ingasebenzi ngezizathu ezihlukahlukene ngakho-ke kufanele iphathwe ngokuqapha.

Ngaphambi kokuhlaziywa, isampula kufanele ibe nemibandela ukuze isuse ukungcola okuboshwe ngokomzimba ebusweni bempushana ngenqubo ebizwa ngokuthi i-degassing noma ukukhipha umoya.Lokhu ngokuvamile kufezwa ngokusebenzisa izinga lokushisa eliphakanyisiwe kusampula ngokuhambisana ne-vacuum noma igesi engasebenzi egeleza njalo.Le nqubo kumele ilawulwe futhi iqashwe ngokucophelela ukuze kukhiqizwe imiphumela enembe kakhulu nephindaphindekayo

1. Amandla kagesi: 220V±10%

2.Ibanga lesibalo sesikhathi: 0.1 isekhondi ukuya kumasekhondi angu-999.9

3.Ukunemba kwesibalo sesikhathi: <0.2 isekhondi

4．Ukunemba kokulinganisa: ≤1‰

5．Izinga lokushisa: 8-34℃

6.Inombolo yendawo yesilinganiso S: 0.1-9999.9cm2/g

三: Sebenzisa incazelo yebhodi

Indawo yeDisplay

Isikrini se-LCD, indawo yokubonisa.

v Indawo yokusebenza

Yakhelwe ngokhiye abangu-8, hlanganisa 【Kwesobunxele】【Kwesokudla】【Phezulu】【Phansi】【Setha kabusha】【S inani】【K inani】【Faka】

四: Izinto zensimbi

u Concrete ratio area ikhombisa indawo yonke yempushana kakhonkolo.

v Indlela incike emoyeni okwazi ukulinganiswa nge-mensurable interspace kanye nongqimba lukakhonkolo oluwugqinsi oluqinile, ukumelana okuhlukile kungaletha ijubane lokugeleza elihlukile, futhi usebenzise lezi zakhi ukuhlola indawo engaphezulu yesilinganiso sikakhonkolo.

w Ngokuvumelana nefomula yokubala evamile ye-GB/T807-2008

S—Indawo Yesilinganiso yesampula yokuhlola, SS— Indawo Yesilinganiso sempushana evamile, cm2/g

T—Umkhawulo woketshezi owehla izikhathi zesampula yokuhlola, TS— Izikhathi zokwehla koketshezi lwempushana, imizuzwana.

η—I-mucosity yomoya lapho isampula yokuhlolwa kuzinga lokushisa elisheshayo, μPa∙s

ηs—I-mucosity yomoya lapho impushana evamile kuzinga lokushisa elisheshayo,μPa∙s

ρ—Ukuminyana kwesampula yokuhlola, ρs—Ukuminyana kwesampula yokuhlola evamile, g/cm3

ε—Izinga le-Interspace lesampula yokuhlola, εs—Izinga lokusebenzisana lesampula elijwayelekile lokuhlola

Kufomula yokubala ngenhla, i-Ngenxa yokuthi i-powderès evamile imisiwe, futhi ingu-0.5, ngakho sebenzisa inani ngendlela efanele.

五、 Ukuhlola nokuhlukanisa imingcele

1）.Sebenzisa i-gag yerabha vala unqenqema lwebhakede bese uhlola, setha ipharamitha edingekayo bese uqala ithuluzi.Uma insimbi ima ngokuzenzakalelayo, hlola ubuso obuwuketshezi uma buphansi, futhi isimo esivamile asikho phansi.

2) Ukuhlolwa kwevolumu yesendlalelo sesampula

六、Inqubo yokuhlola

1) Isampula elungisiwe

2) Qinisekisa ubuningi besampula

3) Isendlalelo sesampula esenziwe
