CAS No. 7783-7-5 Hydrogen Selenide Factory. Ndi omwe amapereka Hydrogen Selenide
Hydrogen selenide, yomwe imadziwikanso kuti hydroselenic acid mu mawonekedwe ake amadzimadzi, ili ndi mankhwala a H₂Se. Nambala yake ya CAS ndi 7783-7-5. Pagululi ndi mpweya wopanda mtundu womwe ndi wapoizoni kwambiri komanso woyaka. Nazi zina mwazinthu za hydrogen selenide:
Katundu Wathupi:
Maonekedwe: Mpweya wopanda mtundu wokhala ndi fungo loyipa lofanana ndi mazira ovunda, ngakhale kuti ndi lowopsa kwambiri.
Malo otentha: -41.4 °C.
Malo osungunuka: -85.4 °C.
Kachulukidwe: Pa STP, ndi yowirira kuposa mpweya.
Kusungunuka: Kusungunuka m'madzi ndi polar organic solvents.
Chemical Properties:
Reactivity: Imagwira ntchito kwambiri ndipo imatha kuyaka yokha mumlengalenga.
Acidity: M'madzi, amapanga asidi ofooka, hydroselenic acid (H₂Se).
Kuwola: Ikhoza kuwola kukhala elemental selenium ndi haidrojeni pansi pazifukwa zina.
Zogwiritsa:
Semiconductor Viwanda: Amagwiritsidwa ntchito popanga ma selenium opangira ma semiconductors ndi zida za photovoltaic.
Analytical Chemistry: Amagwiritsidwa ntchito ngati reagent mu analytical chemistry.
Kafukufuku: Amagwiritsidwa ntchito pofufuza zasayansi popanga zinthu zokhala ndi selenium.
Zolinga Zachitetezo:
Poizoni: Wowopsa kwambiri pokoka mpweya, ngakhale m'malo ochepa; kukhudzana kungayambitse mavuto aakulu azaumoyo kuphatikizapo imfa.
Kuyaka: Mpweya woyaka womwe umatha kupanga zosakaniza zophulika ndi mpweya.
Kugwira: Kumafunikira njira zodzitetezera, kuphatikiza kugwiritsa ntchito zofukiza ndi zida zoyenera zodzitetezera.
Chifukwa cha kawopsedwe komanso momwe amagwirira ntchito, hydrogen selenide sapezeka kawirikawiri kwa ogulitsa mankhwala. M'malo mwake, nthawi zambiri amapangidwa pamalo opangira ma laboratories kapena malo omwe amagwiritsidwa ntchito nthawi yomweyo. Otsatsa apadera omwe amathandizira kumafakitale omwe amafunikira hydrogen selenide ndi omwe amagula chinthuchi, ngakhale kuti ndizofala kwambiri kuti apangidwe pakufunika m'malo mosungidwa kapena kunyamulidwa.
Makampani omwe amapereka hydrogen selenide kapena ma precursors ake angaphatikizepo opanga mankhwala apadera kapena omwe amathandizira makamaka makampani opanga ma semiconductor. Nthawi zonse onetsetsani kuti mukutsatira malamulo am'deralo ndi malangizo achitetezo pogwira ntchito ndi hydrogen selenide, ndikuyigwira pokhapokha poyang'aniridwa ndi njira zoyenera zotetezera.
Shanghai Wechem Chemical Co., Ltd. imapangidwa ndi gulu la akatswiri odziwa zambiri komanso aluso omwe ali ndi chidziwitso chochulukirapo komanso luso laukadaulo pantchito zamagesi apadera komanso ma isotopu okhazikika. Kupyolera mu luso lopitiliza kufufuza ndi ntchito zachitukuko, timapitirizabe kuyambitsa zinthu zapamwamba komanso zoyera kwambiri kuti tikwaniritse zosowa za makasitomala athu. Ngati mukufuna mankhwalawa, chonde omasuka kulankhula nafe nthawi iliyonse!
