Kodi corundum yofiirira ingalowe m'malo mwa corundum yoyera mu zida zopukutira ndi zopukutira? ——Mafunso ndi Mayankho a Chidziwitso
Q1: Kodi corundum yofiirira ndi corundum yoyera ndi chiyani?
Brown corundumndi chinthu chopangidwa ndi bauxite ngati chinthu chachikulu chopangira zinthu ndipo chimasungunuka pa kutentha kwambiri. Gawo lake lalikulu ndiokusayidi wa aluminiyamu(Al₂O₃), yokhala ndi pafupifupi 94% kapena kuposerapo, ndipo ili ndi chitsulo chochepa cha oxide ndi silicon oxide. White corundum ndi chinthu choyera kwambiri, ndipo gawo lake lalikulu ndi aluminiyamu oxide, koma choyera kwambiri (pafupifupi 99%) komanso chopanda zonyansa.
Q2: Kodi kusiyana pakati pa corundum yofiirira ndi corundum yoyera ndi kotani pakulimba ndi kulimba?
Kuuma: White corundum ili ndi kuuma kwakukulu kuposacorundum yofiirira, kotero ndi yoyenera kukonza zinthu zolimba kwambiri. Kulimba: Corundum yofiirira ili ndi kulimba kwambiri kuposa corundum yoyera, ndipo ndi yoyenera pazochitika zomwe zimafuna kukana kwambiri monga kupukuta mopanda mphamvu kapena kupukuta kwambiri.
Q3: Kodi madera akuluakulu ogwiritsira ntchito brown corundum ndi ati?
Chifukwa cha kulimba kwake kwakukulu komanso kuuma kwake pang'ono, brown corundum imagwiritsidwa ntchito makamaka mu: mphamvu yapamwambakupukusazinthu monga kupukusa mopanda mphamvu ndi kupukusa kwambiri. Kukonza zinthu zolimba pang'ono, monga chitsulo, zoumba, ndi matabwa. Kupukuta ndi kuphulitsa mchenga, makamaka kupukuta pamwamba.
Q4: Kodi ntchito zachizolowezi za white corundum ndi ziti?
Chifukwa cha kuuma kwake kwakukulu komanso kuyera kwake kwakukulu, corundum yoyera nthawi zambiri imagwiritsidwa ntchito pa: kupukuta ndi kupukuta molondola, monga kukonza zitsulo zolimba kwambiri ndi chitsulo chosapanga dzimbiri. Kukonza zida zamagetsi ndi zoumba zomwe zimafunikira pamwamba kwambiri. Magawo okonza molondola kwambiri monga zida zamankhwala ndi zida zowunikira.
Q5: Ndi nthawi ziti pamene corundum yofiirira ingalowe m'malo mwa corundum yoyera?
Zochitika zomwe corundum ya bulauni ingalowe m'malocorundum yoyerakuphatikizapo: kuuma kwa zinthu zomwe zakonzedwa ndi kochepa, ndipo kuuma kwake sikuyenera kukhala kwakukulu kwambiri. Zofunikira pakulondola kwa kukonza sizikhala zapamwamba, monga kupukuta pamwamba kapena kuchotsa zinthu zotsalira. Ngati ndalama zochepa zili zochepa, kugwiritsa ntchito brown corundum kungachepetse kwambiri ndalama zomwe zimagwiritsidwa ntchito.
Q6: Ndi nthawi ziti pamene corundum yoyera singalowe m'malo ndi corundum yofiirira?
Zinthu zomwe corundum yoyera singalowe m'malo ndi corundum yofiirira ndi izi: kukonza bwino zinthu zolimba kwambiri, monga chitsulo cha kaboni wambiri ndi chitsulo chosapanga dzimbiri. Kukonza zinthu zomwe zimafunika kwambiri pamwamba, monga kupukuta magalasi owoneka bwino. Kugwiritsa ntchito komwe kumakhudzidwa ndi zinyalala zokwawa, monga zida zachipatala kapena kukonza zinthu za semiconductor.
Q7: Kodi kusiyana kwa mtengo pakati pa corundum yofiirira ndi corundum yoyera ndi kotani?
Zipangizo zazikulu zopangira brown corundum ndi white corundum zonse ndi miyala ya aluminiyamu; koma chifukwa cha njira zosiyanasiyana zopangira, mtengo wopanga brown corundum ndi wotsika, kotero mtengo wake ndi wotsika kwambiri kuposa white corundum. Kwa mapulojekiti omwe ali ndi bajeti yochepa, kusankha brown corundum ndi njira yotsika mtengo.
Q8: Mwachidule, kodi mungasankhe bwanji chotsukira choyenera?
Kusankha corundum yofiirira kapena corundum yoyera kuyenera kutsimikiziridwa malinga ndi zosowa zinazake:
Ngati zosowa zanu zokonzera zinthu zimakhala zopukutira mopanda mphamvu kapena kuwongolera ndalama, ndi bwino kugwiritsa ntchito corundum yofiirira. Ngati zofunikira pakukonza zinthu zili zolondola kwambiri ndipo chinthu chokonzera zinthucho ndi chitsulo cholimba kwambiri kapena zigawo zolondola, corundum yoyera iyenera kusankhidwa. Mwa kuwunika bwino makhalidwe a ziwirizi, mutha kupeza bwino pakati pa magwiridwe antchito ndi mtengo. Ngati muli ndi mafunso, mutha kufunsa akatswiri ena malinga ndi momwe ntchitoyo ikuyendera.
