Chrome corundum

Chrome corundum (yomwe imadziwikanso kuti pinki corundum) imapangidwa ndi zitsulo zobiriwira zamtundu wa chrome ndi aluminiyamu yamafakitale monga zida zopangira, ndipo zimakhudzidwa ndi kutentha kwambiri kuposa madigiri a 2000.Kuchuluka kwa chromium oxide kumawonjezeredwa panthawi yosungunuka, yomwe imakhala yofiirira kapena yotuwa.

Magwiridwe athunthu azinthu za chromium corundum ali ndi mawonekedwe a kuuma kwakukulu, kulimba kwambiri, kuyera kwambiri, kudziwongolera bwino, kukwanitsa kugaya mwamphamvu, kutulutsa kutentha pang'ono, kukana kwa asidi ndi alkali, kukana kutentha kwambiri, komanso kukhazikika kwamafuta.

Mu chromium corundum, kuyambitsa kwa Cr element kumawongolera kulimba kwa abrasive.Kuuma kumakhala kofanana ndi korundum yoyera, ndipo kulimba kwake ndikwapamwamba kuposa kwa white corundum.Zida zopangira ma abrasive zomwe zimapangidwa ndi izo zimakhala ndi kukhazikika kwabwino komanso kumaliza kwambiri.Amagwiritsidwa ntchito kwambiri mu abrasives, pogaya, zipangizo zopukutira, mchenga woponyera mwatsatanetsatane, kupopera mbewu mankhwalawa, zonyamulira mankhwala, zoumba zapadera, ndi zina zotero. .

Chromium corundum imakhala ndi kukhuthala kwakukulu komanso kukana bwino kokwanira chifukwa cha gawo lagalasi lokhala ndi chromium oxide, lomwe lingalepheretse kukokoloka ndi kulowa kwa slag yosungunuka.Amagwiritsidwanso ntchito kwambiri m'minda yotentha kwambiri yokhala ndi malo ovuta, kuphatikiza ng'anjo zazitsulo zopanda ferrous, ng'anjo zosungunula magalasi, makina opangira kaboni wakuda, zoyatsira zinyalala, zotayira zotayira ndi zina zoteteza kutentha kwambiri komanso kuteteza dzimbiri.
