Aluminium yog cov hlau xav tau heev hauv kev tsim kho thiab hauv lwm qhov chaw ntawm tib neeg kev ua haujlwm. Txawm li cas los xij, nws tsis tshua siv hauv nws daim ntawv ntshiab. Feem ntau siv aluminium alloys.
Txhua cov alloys tuaj yeem muab faib ua casting thiab wrought. Thawj hom yog tsim los ntawm melting, thiab rau kev tsim cov alloys ntawm ob hom, siab yog thov. Cast aluminium alloys feem ntau sawv cev los ntawm kev sib xyaw ntawm txhuas nrog silicon. Cov hlau zoo li no muaj zog, muaj kev tiv thaiv corrosion, thiab raug txiav zoo. Raws li rau wrought alloys, duralumin, uas muaj txhuas, magnesium thiab tooj liab, yog paub zoo ntawm lawv. Hlau, profile, nplooj ntawv, daim kab xev yog tsim los ntawm cov hlau no. Koj tuaj yeem ua cov txheej txheem nthuav tawm hauv txhua txoj kev.
Cov khoom ntawm aluminium alloys tuaj yeem muab faib ua lub cev, tshuab thiab tshuaj. Nyob rau hauv cov nqe lus ntawm lub cev khoom, cov alloys yuav luag tib yam ntom li txhuas nws tus kheej. Lawv muaj lub zog siab, uas tuaj yeem sib tw nrog titanium thiab hlau. Tab sis ntawm no nws yuav tsum tau coj mus rau hauv tus account tias qhov kub thiab txiasmelting alloys yog me me (nws yog hais txog 200 degrees). Nws yog tsim nyog sau cia tias aluminium alloys muaj cov thermal conductivity zoo, ua hluav taws xob zoo heev, zoo welded thiab tiv taus corrosion, txawm hais tias cov khoom no ntau dua rau cov ntshiab txhuas.
Raws li cov khoom siv kho tshuab, lawv ua siab dua nrog kev nce qib ntawm alloying. Qhov nthuav qhia aluminium alloys yog siv rau kev tsim cov qauv ntawm cov khoom qis thiab nruab nrab. Nws yog ib qho tsim nyog sau cia tias cov khoom ntawm cov alloys hloov pauv loj tom qab cua sov rau qee qhov kub, uas txiav txim siab siv.
Vim cov hlau yuav tsum tau ua tiav ua ntej siv, thiab cov ntsiab lus ntawm cov hlau yuav tsum tau welded los tsim cov qauv, koj yuav tsum tau xyuam xim rau qhov tseeb tias vuam ntawm aluminium alloys muaj qee yam nta. Cov txheej txheem muaj qee qhov nyuaj:
- alloys nyuaj rau vuam vim yog oxide zaj duab xis uas tshwm rau saum npoo ntawm cov hlau (nws feem ntau cuam tshuam cov seam, uas tiv thaiv kev sib xyaw ua ke ntawm cov npoo ntawm cov hlau);
- oxide zaj duab xis thiab cov hlau nws tus kheej muaj cov ntsiab lus melting sib txawv, thiab qhov sib txawv tuaj yeem yog qhov tseem ceeb;
- txij li qhov kev nthuav dav ntawm aluminium yog qhov siab heev, cov hlau tuaj yeem deformed tom qab vuam;
- alloys muaj fluidity siab, yog li ntawd, thaum vuam, ntws yuav tshwm sim ntawm cov hlau.
Rau vuam ntawm cov alloys, carbon lossishlau electrodes. Cov txheej txheem yog nqa tawm siv ncaj qha tam sim no ntawm rov qab polarity. Ua ntej pib ua haujlwm, qhov saum npoo yuav tsum tau welded yuav tsum tau kho nrog acetone lossis roj av thiab ntxuav nrog txhuam hlau. Txhawm rau vuam kom ua tau zoo dua, nws yog qhov yuav tsum tau ua kom sov cov khoom kom welded mus rau qhov kub thiab txias (200 degrees). Yuav kom tau txais cov seam zoo tom qab vuam, koj yuav tsum txias nws maj mam.
