Qaybta Gaarka ah ee Dhoobada Alumina

Sawirka Gaarka ah ee Qaybta Dhoobada Alumina

Sharaxaad Gaaban:

Saxankan dhoobada ah ee alumina-ka ah ee gaarka loo leeyahay waxaa loo sameeyay warshadaha u baahan saxnaan, xasillooni, iyo cimri dherer heer sare ah marka ay jiraan jawi shaqo oo adag. Iyada oo leh qaab cufan oo godad dhaadheer ah oo lagu buuxiyay godad yaryar oo si isku mid ah loo farsameeyay, qaybtu waxay bixisaa socodka hawada ee la xakameeyey, isku-habayn sax ah, iyo waxqabad dahaadh oo la isku halleyn karo oo loogu talagalay qalabka ku shaqeeya heerkulka sare ama danab sare.

Astaamaha

Jaantus Faahfaahsan

Dulmar Guud

Waxaa laga sameeyay alumina saafi ah oo heer sare ah (95–99.5%), qaybtu waxay bixisaa iska caabin xirasho oo heer sare ah iyo xoog dielectric ah. Jirka dhoobada ah wuxuu si cabbir ahaan u deggan yahay xitaa marka uu la kulmo isbeddellada heerkulka degdegga ah, warbaahinta daxalka, ama hawlgalka joogtada ah ee muddada dheer.

Astaamaha Muhiimka ah

Walax alumina saafi ah oo sarehubinta adkaanta aan caadiga ahayn, dahaarka korontada, iyo iska caabbinta kiimikada
Naqshadeynta safka yar ee godadka yaryarqaybinta socodka hawada, hagidda dareeraha, ama isku-dubaridka qaybaha
Adkaysi kuleyl oo aad u fiican, oo taageeraya hawlgal joogto ah oo heerkul ah 1,000–1,600°C
Ballaarinta kulaylka oo hooseysaawood u siinta waxqabadka xasilloon inta lagu jiro wareegyada kululaynta iyo qaboojinta degdegga ah
Mashiinka saxda ah ee joogtada ah, oo leh dulqaad adag oo ku saabsan joomatari godka iyo booska godka
Ma aha mid gudbisa oo u adkaysta daxalka, oo ku habboon deegaanka danab-sare iyo kuwa soo noqnoqda sare leh
Si buuxda loo habeyn karocabbirrada, qaababka godadka, qaababka, iyo dhammaadka dusha sare

Su'aalaha Badiya La Weydiiyo

S1: Qaybtan dhoobada ah ma u adkaysan kartaa heerkulka sare?
Haa. Dhoobada Alumina waxay caadi ahaan taageertaa 1,000–1,600°C iyadoo ku xiran heerka.

S2: Waa maxay cabbirka ugu yar ee godka la farsamayn karo?
Godadka yaryar ee hoos u dhacaya 0.1–0.2 mm waxaa lagu gaari karaa iyadoo la isticmaalayo laser ama ultrasonic machining.

S3: Qaab-dhismeedka godka ma dib loo habeyn karaa?
Dabcan. Dhammaan safafka, qaababka, iyo qaababka waxaa loo habeyn karaa si gaar ah iyadoo lagu saleynayo sawirrada.
