Ua ntej, qhov tsos thiab muaj pes tsawg leeg
tooj dag thiab tooj liab muaj qhov sib txawv tseem ceeb hauv qhov tsos. tooj dag, raws li nws lub npe qhia, muaj ib tug golden daj luster, du nto thiab nplua nuj kev ntxhib los mos. Ntshav tooj dag, ntawm qhov tod tes, vim tias nws cov ntsiab lus siab purity tooj liab, qhia tau hais tias lub cim ntxim nyiam ntawm cov xim liab liab, kuj muaj glossy thiab tag nrho ntawm kev ntxhib los mos. Qhov sib txawv xim intuitive no ua rau nws yooj yim los txheeb xyuas ob cov hlau hauv peb lub neej txhua hnub.
Nyob rau hauv cov nqe lus ntawm muaj pes tsawg leeg, tooj dag yog ib tug alloy ntawm tooj liab thiab zinc, uas tej zaum kuj muaj me me ntawm lwm yam impurities. Cov muaj pes tsawg leeg ntawm cov hlau no tso cai rau tooj dag los tswj cov khoom tseem ceeb ntawm tooj liab thaum muaj qee yam ntawm zinc, xws li lub zog thiab hardness. Nyob rau hauv sib piv, liab doog tooj liab muaj ib tug kuj homogeneous muaj pes tsawg leeg, muaj xws li tooj liab, uas muaj peev xwm yuav siab li 99.9%, nrog zoo tsis muaj lwm yam impurities. Qhov no siab purity ntawm tooj liab ua rau liab doog tooj liab zoo nyob rau hauv cov nqe lus ntawm hluav taws xob thiab thermal conductivity.
Thib ob, lub cev muaj zog
Vim muaj qhov sib txawv, tooj dag thiab tooj liab hauv lub cev muaj zog muaj qhov sib txawv pom tseeb. Ua ntej ntawm tag nrho cov, nyob rau hauv cov nqe lus ntawm lub zog, tooj dag feem ntau muaj zog dua vim lub complexity ntawm nws alloy muaj pes tsawg leeg. Qhov no ua rau tooj dag kom muaj kev ruaj ntseg zoo dua thaum raug rau sab nraud quab yuam. Violet tooj liab, ntawm qhov tod tes, muaj lub zog tsis tshua muaj zog vim nws feem ntau yog tsim los ntawm ib qho tooj liab uas tsis muaj lwm yam tseem ceeb ntxiv dag zog. Txawm li cas los xij, qhov no tsis txhais tau tias cov tooj liab liab tsis muaj qhov ua tau zoo; ntawm qhov tsis sib xws, nws qhov kev ntxhib los mos ua rau nws muaj txiaj ntsig zoo hauv qee qhov tshwj xeeb.
Thib ob, thaum nws los txog rau qhov ntom ntom, tooj dag feem ntau muaj qhov ntom ntom ntawm 8.52 thiab 8.62, thaum tooj liab liab muaj qhov ntom ntawm 8.9 thiab 8.95. Qhov no txhais tau hais tias qhov ntom ntawm ntshav tooj liab yog qhov siab dua, thiab qhov loj ntawm cov tooj liab liab yog hnyav dua hauv tib lub ntim. Qhov sib txawv ntawm qhov ntom ntom no cuam tshuam rau qee qhov kev xaiv ntawm ob qho khoom siv hauv kev siv tswv yim.
Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm hardness, tooj dag yog nyuaj tshaj li violet tooj liab. Qhov no ua rau tooj dag zoo dua rau cov ntawv thov uas yuav tsum muaj hardness siab dua. Lub softness ntawm ntshav tooj dag, ntawm qhov tod tes, muab nws qhov zoo dua hauv qee qhov chaw uas yuav tsum tau hloov pauv.
Thib peb, thaj chaw ntawm kev thov
tooj dag thiab tooj liab vim lawv cov khoom tshwj xeeb thiab ua lub luag haujlwm tseem ceeb hauv kev siv sib txawv. Brass yog tsuas yog siv nyob rau hauv pej xeem teb, xws li xov hlau, kav dej thiab lwm yam. Qhov no yog vim tooj dag muaj hluav taws xob zoo conductivity thiab corrosion kuj, kom tau raws li qhov yuav tsum tau ntawm kev tsim kho pej xeem ntawm cov khoom siv. Tsis tas li ntawd, tooj dag kuj tau siv dav hauv kev tsim khoom ntawm ntau yam khoom siv kho kom zoo nkauj, ua haujlwm ntawm kev kos duab, thiab lwm yam, nrog nws cov xim daj daj ntxiv xim ci rau tib neeg lub neej.
Violet tooj liab, ntawm qhov tod tes, feem ntau yog siv hauv kev lag luam vim nws cov hluav taws xob zoo heev thiab thermal conductivity. Hauv kev lag luam hluav taws xob thiab hluav taws xob, tooj liab yog siv los ua cov hlau, electrodes thiab lwm yam tseem ceeb ntawm cov khoom; nyob rau hauv kev lag luam tshuaj, tooj liab yog siv los ua ntau yam khoom siv tshuaj thiab cov kav dej vim nws zoo corrosion kuj thiab thermal conductivity. Tsis tas li ntawd, tooj liab violet kuj tau siv dav hauv kev tsim cov duab kos duab, moos, cov cuab yeej thiab lwm yam cuab yeej precision, nrog nws cov purity siab thiab kev ua haujlwm zoo heev los xyuas kom meej qhov zoo thiab qhov tseeb ntawm cov khoom.
Tus nqi nyiaj txiag
Nyob rau hauv cov nqe lus ntawm kev lag luam tus nqi, tus nqi ntawm tooj liab feem ntau yog siab dua tooj dag. Qhov no feem ntau yog vim lub siab purity ntawm tooj liab, kev ua haujlwm nyuaj thiab siv ib zaug xwb. High purity tooj liab yuav tsum tau mus los ntawm ib tug complex refining txheej txheem kom tau, thiab cov txheej txheem yuav tsum tau high-precision cov cuab yeej thiab kev pab txhawb nqa, uas tag nrho cov ua rau zus tau tej cov nqi ntawm tooj liab. Nyob rau hauv sib piv, tooj dag, raws li ib tug tooj liab-zinc alloy, muaj kuj tsis tshua muaj nqi ntau lawm thiab yog pheej yig.
Txawm li cas los xij, qhov no tsis tau txhais hais tias qhov kev thov rau tooj dag hauv kev ua lag luam yog qis dua li tooj liab violet. Qhov tseeb, vim muaj ntau daim ntawv thov ntawm tooj dag hauv pej xeem thiab nws tus nqi qis, nws cov kev xav tau ntawm kev lag luam tau tswj hwm kev loj hlob tsis tu ncua. Txawm hais tias tus nqi ntawm cov tooj liab liab yog siab dua, tab sis vim nws txoj hauj lwm tseem ceeb hauv kev lag luam thiab irreplaceable, nws cov lag luam xav tau kuj muaj zog.
Txhawm rau kom ua tiav, muaj qhov sib txawv tseem ceeb ntawm tooj dag thiab tooj liab nyob rau hauv cov ntsiab lus ntawm cov tsos, muaj pes tsawg leeg, lub cev muaj zog, daim ntawv thov thaj chaw thiab tus nqi nyiaj txiag. Cov kev sib txawv no ua rau ob cov ntaub ntawv hlau no ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv lawv daim ntawv thov. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, daim ntawv thov ntawm tooj dag thiab tooj liab yuav nthuav dav ntxiv, thiab lawv cov txiaj ntsig kev lag luam yuav raug txhim kho tas li.
