Copper tube density thiab kev paub txog kev taw qhia
1. Lub tswv yim taw qhia
Qhov ceev ntawm lub raj tooj liab yog hais txog qhov loj hauv chav tsev ntim ntawm cov khoom siv tooj liab, feem ntau yog siv kilograms / cubic meter (kg / m³) raws li chav ntsuas. Qhov ntom ntom yog ib lub cev kom muaj nuj nqis uas qhia txog qhov compactness ntawm ib yam khoom, uas yog qhov tseem ceeb rau kev xaiv thiab siv cov raj tooj liab.
2. Cov txheej txheem suav
Qhov ntom ntawm lub raj tooj liab tuaj yeem suav los ntawm nws qhov loj thiab ntim. Feem ntau, peb tuaj yeem siv lub ntsuas densitometer los yog caliper, sib npaug thiab lwm yam cuab yeej los ntsuas, thiab tom qab ntawd siv cov qauv ntom ntom los xam.
Qhov ceev (ρ)=mass (m) ÷ ntim (V)
Ntawm lawv, qhov hnyav tuaj yeem ntsuas tau siv qhov sib npaug, thiab qhov ntim tuaj yeem ntsuas tau siv lub caliper lossis lwm yam ntsuas. Nws yuav tsum raug sau tseg tias tib chav tsev yuav tsum tau siv thaum xam.
3. Muaj feem cuam tshuam
Qhov ceev ntawm lub raj tooj liab yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom siv, qhov kub thiab txias, siab, kev tsim khoom, thiab lwm yam ntawm lub raj tooj liab. Feem ntau hais lus, qhov siab dua qhov purity ntawm lub raj tooj liab, qhov ntau dua qhov ntom, thiab qhov kub thiab qhov siab siab dua, qhov ceev ntau dua.
4. Daim ntawv thov teb
Qhov ntom ntawm cov raj tooj liab muaj ntau yam kev siv hauv engineering, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho, kev tsim khoom thiab tshuaj lom neeg kev lag luam. Cov raj tooj liab muaj cov khoom siv hluav taws xob zoo heev, thermal conductivity thiab corrosion kuj, yog li lawv tau siv dav hauv kev tsim cov kav dej, kav dej thiab cov khoom siv cua txias. Tsis tas li ntawd, cov raj tooj liab kuj tseem siv los ua cov khoom siv kos duab, qhia lawv cov txiaj ntsig zoo nkauj tshwj xeeb.
Nyob rau hauv cov ntsiab lus, tooj liab tube ntom yog ib qho tseem ceeb qhia rau kev ntsuas tooj liab tube khoom xaiv, uas yog ib qho tseem ceeb heev rau engineering tsim thiab ntau lawm nyob rau hauv tej hauj lwm. Los ntawm kev nkag siab tob txog kev paub txog tooj liab raj, peb tuaj yeem zoo dua cov haujlwm thiab ua tiav kev txhim khu kev qha ntau thiab nyab xeeb.
