Laboratory Cement Blaine Specific Surface Area Tester

Laboratory Cement Blaine Specific Surface Area Tester

一、 Kufotokozera

Mogwirizana ndi GB/T8074—2008 state standard timapanga mtundu watsopano wa SZB-9 Auto Ratio surface tester.Makinawa amawongoleredwa ndi makompyuta, ndipo amayendetsedwa ndi makiyi okhudza kukhudza kofewa, kuwongolera magalimoto okwana mayeso.Kumbukirani zowerengera, kuwonetsa chiyerekezo cha malo oyeserera mukamaliza kuyesa, imathanso kukumbukira nthawi yoyeserera.

2.

Lingaliro la BET (Brunauer, Emmett ndi Teller) nthawi zambiri limagwiritsidwa ntchito poyesa kuchuluka kwa zotsatsa za gasi ndikupanga chotsatira chapadera chomwe chimafotokozedwa m'magawo adera pamtundu uliwonse wa zitsanzo (m2/g).Njirayi imatchulidwa ndi mabungwe angapo wamba monga ISO, USP ndi ASTM.

Njirayi imagwiritsidwa ntchito kwambiri pazinthu zambiri, koma ndizodalirika pazinthu zomwe zili ndi mtundu wa II kapena mtundu wa IV isotherm yokhala ndi mgwirizano wokwanira pakati pa mpweya wa adsorbate ndi pamwamba.Pazinthu zomwe zili ndi mitundu ina ya isotherms, chiphunzitso cha BET sichingagwire ntchito pazifukwa zosiyanasiyana choncho chiyenera kuchitidwa mosamala.

Asanayambe kusanthula, chitsanzocho chiyenera kukonzedweratu kuti chichotse zonyansa zomangika pamwamba pa ufa mu njira yotchedwa degassing kapena outgassing.Izi zimatheka ndi kugwiritsa ntchito kutentha kwapamwamba pa chitsanzo pamodzi ndi vacuum kapena gasi wolowera mosalekeza.Njirayi iyenera kuyang'aniridwa mosamala ndikuyang'aniridwa kuti apange zotsatira zolondola komanso zobwerezabwereza

1. Mphamvu zamagetsi: 220V ± 10%

2.Kuchuluka kwa nthawi: 0.1sekondi mpaka 999.9 masekondi

3.Kusawerengeka kwa nthawi: <0.2 sekondi

4.Kulondola muyeso: ≤1‰

5．Kutentha kwapakati: 8-34 ℃

6．Chiwerengero cha dera S: 0.1-9999.9cm2/g

三: Kufotokozera kwa board

Malo aDisplay

Ndi LCD skrini, malo owonetsera.

v Malo ogwirira ntchito

Wopangidwa ndi makiyi 8, kuphatikiza 【Kumanzere】【Kumanja】【Mmwamba】【Pansi】【Bwezerani】【S mtengo】【K mtengo】【Lowani】

四: Zida zoimbira

u Konkire chiŵerengero m'dera amasonyeza dera lonse ufa konkire.

v Njira kumadalira mensurable mpweya kudzera mu mensurable interspace ndi wosanjikiza makulidwe konkire wosanjikiza, kukana osiyana akhoza kubweretsa osiyana otaya liwiro, ndi ntchito zinthu zimenezi kuyesa konkire chiŵerengero padziko m'dera.

w Malinga ndi muyezo wowerengera wa GB/T807-2008

S—The Ratio area of ​​test sample, SS— The Ratio area of ​​standard powder, cm2/g

T - Kuchepetsa kwamadzi nthawi zoyeserera, TS - The standard powder fluid down times, seconds.

η—Mphepo yam'mlengalenga pamene chitsanzo choyesera kutentha nthawi yomweyo, μPa∙s

ηs—Mpweya mucosity pamene muyezo ufa mu kutentha yomweyo,μPa∙s

ρ—Kuchulukana kwa zitsanzo zoyezetsa, ρs—Kuchulukirachulukira kwa zitsanzo zoyezera, g/cm3

ε—Mlingo wapakati wa zitsanzo zoyezetsa, εs—Mlingo wa mawonekedwe a zitsanzo zoyezera

Pamwambapa mawerengedwe kachitidwe, Chifukwa chakuti muyezo ufa ufa ndi wokhazikika, ndipo ndi 0.5, choncho gwiritsani ntchito mtengo molondola.

五、 Mayeso ndi malire

1）.Gwiritsani ntchito rabala gag kusindikiza m'mphepete mwa chidebe ndiye yesani, ikani chizindikiro chofunikira kenako yambitsani chida.Chidacho chikayima, yang'anani nkhope yamadzimadzi ngati ili pansi, ndipo mawonekedwe ake satsika.

2）Chitsanzo cha kuyesa kwa voliyumu

六, Njira yoyesera

1) Chitsanzo chokonzedwa

2) Tsimikizirani kuchuluka kwachitsanzo

3) Zitsanzo zosanjikiza zopangidwa
