Malo
Kuyera Kwambiri 5n mpaka 7n (99.999% mpaka 99.99999%) Selenium (en)
Zolemba zimayambitsa
Mankhwala ndi mankhwala:
Selenium ili ndi kulemera kwa atomiki ya 78.96; Kuchulukitsa kwa 4.81g / cm3 ndipo ali ndi zinthu zowoneka bwino zomwe zimapangitsa kuti zikhale zofunikira pazogwiritsa ntchito zosiyanasiyana. Imakhala ndi mawu osungunuka 221 ° C; malo otentha a 689.4 ° C, yomwe imatsimikizira kukhazikika kwake komanso kudalirika kwake ngakhale zitafika.
Mitundu Yosiyanasiyana:
Mitundu yathu ya selenium imapezeka m'miyala, ufa, mabatani ndi mitundu ina yosinthira njira ndi mapulogalamu osiyanasiyana.
Kuchita Zabwino Kwambiri:
Chiyero chathu chachikulu chitsiritso chikafikire mosagwirizana, kukumana ndi miyezo yokhazikika kwambiri komanso zoyembekezera zambiri mu pulogalamu iliyonse. Kuyera kwapadera kumapangitsa kuti kusandulika ndi kudalirika kwa osawoneka bwino mu njira yanu.
Ntchito Zogwirira Ntchito
Ulimi:
Selenium ndi imodzi mwazinthu zofunika kumera, ndipo kuchepa kwa Selenium kungayambitse kukula kwa mbewu. Chifukwa chake, zigawenga zitsulo zimatha kusintha zokolola ndi mtundu wazomera.
Chitetezo Chachilengedwe:
Selenium itha kugwiritsidwa ntchito ngati othandizira madzi kuti achotse bwino zodetsa zoipitsitsa zamadzi, ndipo amathanso kugwiritsidwa ntchito mu dothi komanso phytorediation kuti ithandizire kuchepetsa kuchuluka kwa dothi ndi madzi.
Makampani:
Selenium ili ndi zithunzi za zithunzi ndi Semiconductor, ndipo nthawi zambiri zimagwiritsidwa ntchito popanga jocroclols, ojambula, olamulira opezeka, etc.
Metallorgical:
Selenium imathandizira kukonza zinthu za chitsulo ndipo nthawi zambiri kumagwiritsidwa ntchito popanga ma metallical.
Zamankhwala:
Selenium ili ndi antioxidant komanso anti-kutupa zinthu, zomwe zimathandizira kupewa matenda amtima, khansa, matenda a chithokomira, etc. Zimathandizanso kuteteza chitetezo cha thupi.
Kusamala ndi kukonza
Kuonetsetsa kuti mukugwiritsa ntchito bwino, timagwiritsa ntchito njira zokhazikika, kuphatikizapo makanema apulasitiki kapena polyester films pambuyo polyethylene valuum, kapena chubu chagalu chagalum. Njira izi zimateteza chiyero komanso mtundu wa zotupa ndi kusamalira bwino komanso kuchita.
Chiyero chathu chachikulu chiyera ndi Chipangano Choyenera chatsopano, chabwino ndi magwiridwe antchito. Kaya muli ku ulimi, wogulitsa, kuteteza chilengedwe kapena gawo lina lililonse lomwe likufuna zida zapamwamba, selenium yathu imatha kukulitsa njira zanu ndi zotsatira zake. Lolani zitheke za ma nezatium athu tisakupatseni mwayi wopambana - mwalaworkornor of kupita patsogolo ndi zatsopano.
