Chepetsani phokoso la magalimoto, kuya kwa zomangamanga kumathandizira kuyamwa mafunde amawu, ndipo mphamvu yochepetsera phokoso imatha kufikira 30%.
Galasi Yowunikira Mikanda yaukadaulo yaukadaulo
â Kukula: 90-1180um (Malingana ndi zofunika)
â¡Kuzungulira: > 80% (Malingana ndi zofunikira)
⢠Mlozera wowonekera: > 1.5
â£Chigawo: pafupifupi. 2.5
1 Mtengo wosungunuka ndi 2/3 yokha ya aluminiyumu
2 Die casting kupanga bwino ndi 25% apamwamba kuposa aluminiyamu, kuponya nkhungu ndi 300-500K kuposa aluminiyamu, ndipo kutayika kwa thovu ndi 200% kuposa aluminium.
3 Maonekedwe a pamwamba ndi maonekedwe a magnesiamu amawonekera bwino kuposa aluminiyamu (chifukwa kutentha kwa nkhungu kumachepetsedwa, maulendo oyendera amatha kuchepetsedwa)
Pakali pano, pali njira ziwiri zazikulu zokonzekera mafakitale zitsulo kashiamu kunyumba ndi kunja: electrolysis ndi kuchepetsa matenthedwe. Cholinga chake ndi njira, zida ndi kupita patsogolo kwa vacuum distillation pokonzekera zitsulo zoyera kwambiri za calcium. Electrolysis ndi kuchepetsa kutentha ndi njira zoyeretsera mankhwala zomwe zimakhala zovuta Kukonzekera kashiamu woyeretsedwa kwambiri wachitsulo. Pogwiritsa ntchito kashiamu wa mafakitale monga zopangira, kutsekemera kwa vacuum kungagwiritsidwe ntchito pokonzekera calcium yoyera yachitsulo yokhala ndi chiyero choposa 99.999% (5N).
M'dziko lathu, kashiamu adawoneka ngati zitsulo, zomwe zidayambanso ku imodzi mwama projekiti akuluakulu othandizidwa ndi Soviet Union kudziko lathu isanafike 1958, bizinesi yamagulu ankhondo ku Baotou. Kuphatikizapo njira yamadzimadzi cathode (electrolysis) zitsulo zopanga calcium. Mu 1961, mayeso ang'onoang'ono adapanga calcium yoyenerera.
Makampani opanga mabatire a lead-acid m'dziko langa ali ndi mbiri yopitilira zaka zana. Chifukwa cha mawonekedwe a zida zotsika mtengo, ukadaulo wosavuta, ukadaulo wokhwima, kudzitsitsa pang'ono, komanso zofunikira zopanda kukonza, zidzalamulirabe msika muzaka makumi angapo zikubwerazi.
