Minda yogwiritsira ntchito ndi ubwino wa mchenga wa brown corundum
Mchenga wa brown corundum, wotchedwanso brown corundum kapenabrown fused corundum, ndi mtundu wa abrasive wochita kupanga wopangidwa ndi bauxite wapamwamba kwambiri monga zopangira zazikulu, zosungunuka ndi kuzizizira pa kutentha kwambiri kuposa 2000 ℃ mu ng'anjo yamagetsi yamagetsi. Chigawo chachikulu ndi aluminium oxide (Al₂O₃), ndipo zomwe zili pamwambazi zimakhala pamwamba pa 95%. Chifukwa cha kuuma kwake kwakukulu, kulimba kwabwino, kukana kuvala mwamphamvu komanso kukana kutentha kwambiri, kumagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Ndikusintha kosalekeza kwa zofunikira pakukonza zinthu, kugwiritsa ntchito mchenga wa brown corundum muzotayira, zida zowumbitsira, chithandizo chapamwamba, kuponyera ndi ma fillers ogwira ntchito akukhala kofunika kwambiri.
1. Lonse ntchito mu abrasives
Ma Abrasives ndi amodzi mwamagawo achikhalidwe komanso ofunikira kwambiri a brown corundum. Chifukwa cha kuuma kwake kwa Mohs mpaka 9.0, yachiwiri kwa diamondi ndi silicon carbide, corundum ya bulauni imagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zowononga, monga mawilo opera, nsalu za emery, sandpaper, miyala yamafuta ndi mitu yopera. Kaya mukukonza zitsulo, kupukuta magalasi kapena kugaya ceramic, corundum ya bulauni imatha kupereka mphamvu yodula bwino komanso kukana kuvala bwino. Makamaka m'mafakitale omwe amafunikira kudula mwamphamvu komanso kusunga mawonekedwe okhazikika, ma abrasives a brown corundum amachita bwino kwambiri.
2. Monga zofunika zopangira zipangizo refractory
Brown corundum imakhala ndi kutentha kwapamwamba kwambiri komanso kukhazikika kwamafuta ambiri, motero imagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zodzitchinjiriza. Mung'anjo zamakampani zotentha kwambirimonga zitsulo, zitsulo, simenti, ndi galasi, bulauni corundum angagwiritsidwe ntchito kupanga apamwamba kalasi refractory njerwa, castables, mapulasitiki, ramming zipangizo ndi mankhwala ena refractory, makamaka kwa mbali ndi kwambiri kukokoloka kwapamwamba-kutentha ndi pafupipafupi matenthedwe mantha. Poyerekeza ndi zida zamtundu wa aluminiyamu, zida za brown corundum refractory zimakhala ndi kukokoloka kwa slag komanso kukana kwa spalling, kumakulitsa moyo wautumiki wa zida ndikuchepetsa mtengo wokonza mabizinesi.
3. Kugwiritsa ntchito mukulima mchengandi mankhwala pamwamba
Mchenga wa Brown corundum umagwiritsidwa ntchito kwambiri pazitsulo zachitsulo pamwamba pa mchenga chifukwa cha kukula kwake kwa tinthu ting'onoting'ono, kuuma kwakukulu ndi mphamvu yokoka kwambiri. Panthawi yopanga mchenga, corundum ya bulauni imatha kuchotsa dzimbiri, sikelo, utoto wakale wa utoto, ndi zina zambiri pamwamba pa chogwirira ntchito, ndikuwongolera ukhondo ndi kumamatira. Panthawi imodzimodziyo, chifukwa cha kudzinola bwino komanso kosavuta kusuntha, imatha kubwezeretsedwanso ndikugwiritsidwa ntchito nthawi zambiri, kuchepetsa kwambiri ndalama zakuthupi. Kuphatikiza apo, corundum ya bulauni imawonetsanso zotsatira zapadera pamankhwala a matte ndi kapangidwe kapamwamba ka zinthu monga chitsulo chosapanga dzimbiri, mbiri ya aluminiyamu, magalasi, ndi zoumba.
4. Kugwiritsa ntchito kuponya molondola
M'zaka zaposachedwapa, ndi mosalekeza chitukuko cha mwatsatanetsatane kuponyera luso, zofunika apamwamba akhala patsogolo kwa chiyero ndi kukhazikika matenthedwe kuponya zipangizo.Brown corundum chakhala chipolopolo choyenera chazitsulo zomveka bwino monga ma aloyi otentha kwambiri, zitsulo zosapanga dzimbiri, ndi zitsulo za carbon chifukwa cha kukhazikika kwake kwa mankhwala, kutsekemera kwabwino kwa matenthedwe, ndi kutsika kwa mphamvu yowonjezera kutentha. Mchenga wa Brown corundum ukhoza kupititsa patsogolo mawonekedwe apamwamba a castings ndikuchepetsa zolakwika zoponya. Amagwiritsidwa ntchito kwambiri m'magawo opanga zinthu zapamwamba monga ndege, magalimoto, ndi mphamvu.
5. Kugwiritsa ntchito nthawi yayitali ngati chodzaza chogwira ntchito
Brown corundum ingagwiritsidwenso ntchito ngati chophatikizira chogwira ntchito muzinthu monga anti-slip floors, misewu yosamva kuvala, matope a resin, ndi zida zomangira zapamwamba. Kuuma kwake kwabwino kwambiri komanso kukana kwapang'onopang'ono kumathandizira kukonza kukana kuvala ndi moyo wautumiki wa zida zophatikizika. Pazinthu zamagetsi, zoumba, mphira, etc., brown corundum micropowder imagwiritsidwanso ntchito ngati chodzaza kuti chiwongolere kukana kutentha, kutentha kwamafuta, komanso mphamvu zamapangidwe azinthu.
Mapeto
Mchenga wa Brown corundum umagwira ntchito yofunika kwambiri pamakampani amakono omwe ali ndi mawonekedwe abwino kwambiri komanso kukhazikika kwamankhwala. Ndi kukweza kwaukadaulo wazinthu komanso zosowa zamafakitale, chiyembekezo chamsika wamchenga wa brown corundum chidzakhala chokulirapo ndipo chidzabweretsanso mayankho ogwira mtima komanso osamalira chilengedwe kumafakitale angapo.
