Aluminium alloy qhov rooj thiab qhov rais yog cov khoom siv feem ntau siv qhov rooj thiab qhov rais hauv cov tsev niaj hnub. Lawv muaj qhov zoo ntawm kev sib sib zog nqus, ruaj khov, zoo nkauj zoo nkauj, thiab tsis ua rau corrosion. Txawm li cas los xij, qee zaum peb pom tias qee qhov aluminium alloy qhov rooj thiab qhov rais yog deformed, uas cuam tshuam rau lawv lub neej kev pab cuam thiab zoo li. Yog li vim li cas qhov no tshwm sim?
1. Tej yam ntuj tso
Tej yam ntuj tso yog ib yam tseem ceeb uas cuam tshuam rau lub deformation ntawm aluminium alloy qhov rooj thiab qhov rais. Txij li thaum lub qhov rooj thiab qhov rais nyob sab nraum zoov, lawv yuav raug cuam tshuam los ntawm kev hloov pauv huab cua, xws li hnub ci hnub ci, huab cua los nag, cua, thiab lwm yam, uas yuav muaj kev cuam tshuam rau aluminium alloy qhov rooj thiab qhov rais. Piv txwv li, nyob rau hauv cov huab cua kub, qhov kub ntawm aluminium alloy qhov rooj thiab qhov rais yuav tsis tshua muaj siab, thiab lawv yog feem ntau nthuav, deformation los yog tawg; Thaum lub caij ntuj no txias, thaum huab cua sab nraum zoov kub tsawg heev, aluminium alloy qhov rooj thiab qhov rais yuav deformed vim shrinkage.
2. Cov teeb meem khoom siv
Cov ntaub ntawv tseem yog ib qho ntawm cov laj thawj tseem ceeb uas cuam tshuam rau qhov deformation ntawm aluminium alloy qhov rooj thiab qhov rais. Cov ntaub ntawv tsim khoom thiab cov txheej txheem tsim khoom ntawm aluminium alloy qhov rooj thiab qhov rais yuav cuam tshuam rau qhov zoo thiab kev pabcuam lub neej ntawm lub qhov rooj thiab qhov rais. Yog tias cov khoom siv tsis zoo lossis cov txheej txheem kev ua haujlwm tsis yog tus qauv, lub qhov rooj thiab qhov rais yuav muaj deformation thiab lwm yam teeb meem. Piv txwv li, qhov zoo ntawm cov iav thiab khoom siv hauv aluminium alloy qhov rooj thiab qhov rais yuav cuam tshuam ncaj qha rau lawv qhov ruaj khov thiab ua haujlwm ntev tom qab kev teeb tsa.
3. teeb meem kev teeb tsa
Kev txhim kho zoo yog ib qho tseem ceeb cuam tshuam rau qhov deformation ntawm aluminium alloy qhov rooj thiab qhov rais. Yog tias qhov kev teeb tsa ntawm lub qhov rooj thiab qhov rais tsis yog tus qauv thiab cov hlua khi, cov ntaub qhwv roj hmab, thiab lwm yam ntawm lub qhov rooj thiab qhov rais tsis raug ntsia kom raug, teeb meem xws li xoob ntawm lub qhov rooj thiab qhov rais yuav tshwm sim. Yog tias tsis muaj qhov sib txawv ntawm lub qhov rooj thiab qhov rais thiab lub qhov rooj ncej, nws yooj yim rau lub qhov rooj thiab qhov rais kom deform los yog tawg vim thermal expansion thiab contraction ntawm ib puag ncig.
4. Cov teeb meem siv
Kev siv thiab kev saib xyuas ntawm aluminium alloy qhov rooj thiab qhov rais kuj yog ib qho tseem ceeb hauv kev zam deformation. Yog tias lub qhov rooj thiab qhov rais raug rau sab nraud quab yuam xws li kev cuam tshuam thiab kev sib tsoo ntev, lub qhov rooj thiab qhov rais yuav deformed; thiab yog tias lawv tsis tau khaws cia rau lub sijhawm ntev, cov plua plav thiab lwm yam av ntawm lub qhov rooj thiab qhov rais yuav yooj yim rau cov tshuaj tiv thaiv electrochemical hauv lub computer, ua rau kom dawb, oxidation, corrosion, thiab lwm yam ntawm cov khoom siv txhuas ntawm lub qhov rooj thiab qhov rais. Deformation thiab lwm yam tshwm sim.
