DRK6210 Series Automatic Specific Surface Area kanye Porosity Analyzer

Uchungechunge lwezindawo ezizenzakalelayo eziqondile ngokuphelele kanye nabahlaziyi be-porosity lubhekisela ku-ISO9277, ISO15901 amazinga wamazwe ngamazwe kanye namazinga kazwelonke we-GB-119587, ngokomgomo wokulinganisa wendlela yevolumu emile, nge-mass balance equation, ibhalansi yegesi emile kanye nesilinganiso sokucindezela ukuhlola i-adsorption. kanye nenqubo ye-desorption, inqubo yokuhlola Yenziwa ezingeni lokushisa le-nitrogen eliwuketshezi.

Ngemuva kokuthi inani legesi elaziwayo ligcwaliswe kushubhu yesampula, lizobangela ukwehla kwengcindezi. Kusukela kulokhu, isisindo se-molar yegesi ye-adsorbed ekulinganisweni kwe-adsorption singabalwa. Ngomthamo we-adsorption olinganisiwe olinganisiwe, imodeli yetiyori isetshenziselwa ukuthola indawo eqondile ye-BET enamaphuzu amaningi, indawo ethile ye-Langmuir yesampula ehloliwe; Ivolumu ye-mesopore ye-BJH kanye ne-macropore, ukusatshalaliswa kwendawo, umthamo wembobo ophelele; i-t-plot micropore Ivolumu nendawo engaphezulu, ukusatshalaliswa kwe-micropore yaseDubinin-Astakhov, ukusatshalaliswa kwe-micropore ye-Horvath-Kawazoe; i-density function theory (DFT) kanye ne-Monte Carlo (MC) imodeli yokusabalalisa usayizi wezimbotshana kanye namanye amapharamitha.

I-Modular gas circuit design
I-drk-6210 uchungechunge oluzenzakalelayo endaweni ethile yendawo kanye ne-porosity analyzer
Uchungechunge lwezindawo ezizenzakalelayo eziqondile ngokuphelele kanye nabahlaziyi be-porosity bethula imiqondo yedizayini ethuthuke kakhulu emhlabeni namuhla, bamukele umklamo oyingqayizivele wemodyuli we-vacuum yensimbi engagqwali eyingqayizivele kanye nezinyathelo ezithuthukisiwe zokulwa nokuvuza nokungangcoli ukuze kuqinisekiswe ukufezeka kwevacuum ephezulu. futhi ugweme Ububi bokuvuza kalula ngenxa yokuhlangana kwamapayipi amaningi.

Izinga lokushisa elijwayelekile
I-Dewar flask yensimbi eyakhiwe ngokwayo ingagcina i-nitrogen ewuketshezi izinsuku ezingaphezu kweziyishumi ngenxa yesakhiwo sayo sangaphakathi esiyingqayizivele. Ngesikhathi sokuhlolwa, cishe akukho ukulahleka kwe-nitrogen ewuketshezi, ngaleyo ndlela kuqinisekisa izinga lokushisa eliqhubekayo lesampula elihloliwe futhi kugwenywe ibhodlela lengilazi. Isici sokuthi ibhodlela le-terracotta libuthakathaka futhi alikwazi ukunyakaza.

Inzwa yokunemba okuphezulu
Izinzwa eziningi zokunemba okuphezulu kanye namadivayisi okuguqula angu-22-bit AD aqinisekisa ukunemba kwendawo ethile kanye nezibalo zokuvula.
Imodeli yetiyetha ethuthukisiwe
I-Advanced density function theory (DFT) kanye ne-Monte Carlo (MC) imodeli yokusabalalisa usayizi wezimbotshana zisungule isikhundla esiphezulu endaweni ethile yezwe lami kanye nemboni yokuhlaziya i-porosity, futhi isezingeni eliphambili emhlabeni.
Ukusebenza okuzenzakalelayo
Inqubo ye-adsorption kanye ne-desorption konke kulawulwa yikhompyutha, ngaphandle kokusebenza ngesandla

Izici zobuchwepheshe:
1. Indawo eqondile ye-BET enamaphuzu amaningi, indawo ethize ye-Langmuir
2. I-BJH mesopore kanye nevolumu ye-macropore, ukusatshalaliswa kwendawo, umthamo wembobo ophelele
3. T-plot ivolumu ye-micropore nendawo engaphezulu,
Ukusatshalaliswa kwama-micropore eDubinin-Astakhov,
Ukusatshalaliswa kwe-micropore ye-Horvath-Kawazoe
4. Ithiyori yomsebenzi wokuminyana (DFT) kanye nemodeli yokusabalalisa usayizi wezimbotshana ze-Monte Carlo (MC).

Umbiko wokuphumayo:
Ukuphrinta okuqondile kanye nokukhishwa kwe-EXCEL kwe-adsorption ne-desorption isotherm, indawo ethize ye-BET, indawo ethize ye-Langmuir, ivolumu ye-t-plot micropore, ivolumu ye-BJH pore, indawo ye-pore, isamba sembobo esiphelele, indawo ephelele ye-pore, i-Dbinin-Astakhov, i-Horvath-Kawazoe micropores. Ukusabalalisa, ukusatshalaliswa kwezimbotshana ze-NLDFT/GCMC, umbiko ofinyeziwe.
Ibanga lesicelo:
Ucwaningo nokuhlolwa komkhiqizo kwezinto ezihlukahlukene, okuhlanganisa ukukalwa kwezinto ezihlukahlukene ezifana ne-zeolite, isisefo samangqamuzana, i-silica, i-alumina, inhlabathi, ubumba, i-catalyst, i-organometallic compound framework structure, njll.
