Makhalidwe a aluminium silika woyenera 1

Mu zokambirana zopanda zitsulo zoponyera, mtundu wa mtundu wa bokosi lotsutsana ndi bokosi umagwiritsidwa ntchito kwambiri kuti usungunusule zitsulo ndi kutentha & zouma zinthu zosiyanasiyana. Mphamvu zomwe zimadyedwa ndi maakaunti a Zipangizozi pazigawo zambiri zamagetsi zomwe zimagwiritsidwa ntchito ndi malonda onse. Momwe mungagwiritsire ntchito ndi kupulumutsa mphamvu ndi imodzi mwazinthu zovuta zomwe mafakitale amafunikira kuthana nalo. Nthawi zambiri, kutengera njira zopulumutsira mphamvu zopulumutsa mphamvu ndizosavuta kuposa kukhala ndi mphamvu zatsopano, komanso ukadaulo wotetezedwa ndi imodzi mwamisamu yopulumutsa mphamvu zomwe ndizosavuta kugwiritsa ntchito ndipo zagwiritsidwa ntchito kwambiri. Mwa zina mwathunthu zodzitchinjiriza, chiberekero chotsimikizika cha alumine chimakhala chamtengo wapatali ndi anthu chifukwa cha magwiridwe ake apadera, ndipo amagwiritsidwa ntchito kwambiri m'makalasi osiyanasiyana a mafakitale.

Aluminium silika yodziyimira ndi mtundu watsopano wazosintha komanso zotchinga zamafuta. Ziwerengero zimawonetsa kuti kugwiritsa ntchito ma aluminium sikono ngati renctictory kapena zotchinga za ng'anjo yolimbana ndi mphamvu zopitilira 20%, zina mpaka 40%. Chitsamba cha aluminiyamu chotsimikizika chili ndi izi.
(1) Kulimba kwa kutentha
Wambachiberekero cha aluminiumNdi mtundu wa ma amorphous fiber yopangidwa ndi dongo lolowera, bauxite kapena zida zapamwamba za alumina zokhala ndi njira zapadera zozizira. Kutentha kwa ntchito nthawi zambiri kumakhala pansi 1000 ℃, ndipo ena atha kufikira 1300 ℃. Izi ndichifukwa choti kutentha komanso kutentha kwa kutentha kwa aluminium sinctictory yolimba imakhala pafupi ndi mpweya. Imakhala ndi ulusi wolimba komanso mpweya, wokhala ndi nkhawa yoposa 90%. Chifukwa cha kuchuluka kwa mpweya wotsika ndikudzaza ma pores, ma network mosalekeza a mamolekyulu olimba a mamolekyulu odalirika, omwe amayamba kuwononga kutentha komanso kungochita.
Nkhani yotsatira tidzapitilizabe kubweretsa mikhalidwe ya aluminium silika. Chonde khalani okonzeka!
