ILabhoratri yeSamente iBlaine yoMvavanyi weNdawo eKhethekileyo

ILabhoratri yeSamente iBlaine yoMvavanyi weNdawo eKhethekileyo

一、Ukucaciswa

Ngokuvumelana ne-GB/T8074—2008 umgangatho welizwe siphuhlisa imodeli entsha ye-SZB-9 Auto Ratio umphezulu tester.Umatshini ulawulwa yikhompyuter, kwaye iqhutywa ngezitshixo zokuchukumisa ezithambileyo, inkqubo yovavanyo lolawulo oluzenzekelayo.Khumbula ngokuzenzekela i-coefficient, bonisa umyinge wexabiso lendawo yomphezulu ngokuthe ngqo emva kokuba umsebenzi wovavanyo ugqityiwe, inokukhumbula ngokuzenzekelayo ixesha lovavanyo.

Ithiyori ye-BET (i-Brunauer, i-Emmett kunye ne-Teller) isetyenziswa ngokuqhelekileyo ukuvavanya idatha ye-adsorption yegesi kunye nokuvelisa umphumo ocacileyo wendawo echazwe kwiiyunithi zendawo ngobunzima besampulu (m2 / g).Ubuchwephesha buchazwa yimibutho emininzi esemgangathweni efana ne-ISO, USP kunye ne-ASTM.

Le ndlela isetyenziswa ngokubanzi kwizinto ezininzi, kodwa inokwethenjelwa kakhulu kwizinto ezinohlobo lwe-II okanye uhlobo lwe-IV isotherm enezinga elaneleyo lokusebenzisana phakathi kwegesi ye-adsorbate kunye nomphezulu.Kwiimathiriyeli kunye nezinye iintlobo ze-isotherms, ithiyori yeBET ayinakusebenza ngezizathu ezahlukeneyo kwaye ke kufuneka iphathwe ngononophelo.

Ngaphambi kokuhlalutya, isampuli kufuneka ilungiswe kwangaphambili ukuze isuse ukungcola okubanjwe ngokomzimba ukusuka kumphezulu womgubo kwinkqubo ebizwa ngokuba yi-degassing okanye i-outgassing.Oku kudla ngokufezekiswa ngokufaka ubushushu obuphezulu kwisampulu ngokudityaniswa ne-vacuum okanye igesi engasebenziyo eqhubekayo.Le nkqubo kufuneka ilawulwe ngononophelo kwaye ibekwe esweni ukuze ivelise ezona ziphumo zichanekileyo neziphindaphindwayo

1. Amandla ombane ombane: 220V±10%

2.Uluhlu lokubala ixesha: 0.1sekhondi ukuya 999.9 imizuzwana

3.Ukuchaneka kokubala ixesha: <0.2 isekhondi

4.Ukuchaneka komlinganiselo: ≤1‰

5.Uluhlu lobushushu: 8-34℃

6.Umlinganiselo wenombolo yendawo S: 0.1-9999.9cm2/g

三: Sebenzisa inkcazo yebhodi

uDisplay indawo

Ngaba isikrini se-LCD, indawo yokubonisa.

v Indawo yokusebenza

Yenziwe ngezitshixo ezisi-8, zibandakanya 【Ekhohlo】【Ekunene】【Phezulu】【Ezantsi】【Seta kwakhona】【S ixabiso】【K ixabiso】【Ngena】

四: Izinto zesixhobo

u Umlinganiselo weConcrete ratio ubonisa indawo epheleleyo yomgubo wekhonkrithi.

v Indlela ixhomekeke emoyeni mensurable ngokusebenzisa kwi interspace mensurable kunye umaleko obungqingqwa obuqinileyo ikhonkrithi, ukumelana ezahlukeneyo kunokuzisa isantya sokuqukuqela ezahlukeneyo, kwaye usebenzise ezi elementi ukuvavanya umlinganiselo wekhonkrithi umphezulu indawo.

w Ngokomgangatho wokubala oqhelekileyo we-GB/T807-2008

S—Ummandla weRetio yesampula yovavanyo, i-SS— Indawo yeRetio yomgubo oqhelekileyo, i-cm2/g

T-Ulwelo umda phantsi amaxesha isampuli uvavanyo, TS- Ulwelo ngumgubo umgangatho phantsi amaxesha, imizuzwana.

η—I-mucosity yomoya xa isampulu yovavanyo kwiqondo lobushushu elikhawulezileyo, μPa∙s

ηs—Ubumdaka bomoya xa umgubo oqhelekileyo kwiqondo lobushushu elikhawulezileyo,μPa∙s

ρ—Ubuninzi besampulu yovavanyo, ρs—Ubuninzi besampulu yovavanyo oluqhelekileyo, g/cm3

ε—Ireyithi yesithuba sesampulu yovavanyo, εs—Ireyithi yojongano lwesampulu eqhelekileyo yovavanyo

Kwifomula yokubala ngasentla, i-Ngenxa yokuba i-powderès eqhelekileyo imisiwe, kwaye yi-0.5, ngoko sebenzisa ixabiso ngokuchanekileyo.

Umzekelo: Uvavanyo kunye nomda

1）.Sebenzisa irabha yegag itywine umphetho webhakethi emva koko uvavanye, seta iparamitha eyimfuneko emva koko uqalise isixhobo.Xa isixhobo auto stop, khangela ubuso elulwelo ukuba phantsi, kwaye isimo eqhelekileyo akukho phantsi.

2) Uvavanyo lomthamo wesampulu

六、 Inkqubo yovavanyo

1) Isampuli elungisiweyo

2) Qinisekisa ubungakanani besampulu

3) Isampuli yomaleko eyenziwe

●GB/T8074-2008 Okunye akuzange kubhengezwe, ungabhekisa kwi-Standard GB/T8074-2008
