Qhov kub dua, qhov muaj zog dua cov kua qaub kom yaj nws. Ntsuas qhov muaj zog ntawm nitric acid yog siv los ntsuas 14k thiab qis dua. Aqua regia Aqua regia Aqua regia (/ˈreɪɡiə, ˈriːdʒiə/; los ntawm Latin, lit. "regal water" los yog "royal water") yog ib tug sib tov ntawm nitric acid thiab hydrochloric acid, zoo nyob rau hauv ib tug molar ratio ntawm 1:3. https://en.wikipedia.org › wiki › Aqua_regia
Aqua regia - Wikipedia
sib tov ntawm ib feem ntawm nitric acid thiab peb qhov chaw hydrochloric acid, yog siv los ntsuas siab dua karat purity los ntawm cov txheej txheem ntawm kev sib piv thiab tshem tawm.
Koj ua li cas ntsuas kub nrog nitric acid?
Nitric Acid Test
Kub yog cov hlau zoo uas txhais tau tias nws tiv taus corrosion, oxidation thiab acid. Txhawm rau ua qhov kev sim no, rub koj cov kub ntawm lub pob zeb dub kom tawm ntawm qhov pom. Tom qab ntawd siv nitric acid rau lub cim. Cov kua qaub yuav yaj cov hlau hauv paus uas tsis yog kub tiag.
ntsuas kub npaum li cas?
Nyob rau saum nws, ntsuas kua qaub tsis yog ib txwm muaj tseeb. Cov khoom siv kua qaub feem ntau muaj cov khoom siv los ntsuas 10k, 14k, 18k, thiab 22k kub. Cov kua qaub puag ncig mus rau qhov ze tshaj plaws kev daws teeb meem; nws tsis tuaj yeem qhia koj yog tias nws yog 13K lossis 18.5K. Koj yuav tsum ntseeg tias koj cov neeg ua haujlwm yuav paub txhua yam no thiab txhais cov txiaj ntsig tau raug.
Qhov zoo tshaj plaws los ntsuas kub yog dab tsi?
Kev kuaj kos yog txoj hauv kev zoo los txiav txim siab yog tiaskoj cov hniav nyiaj hniav kub yog kub tiag, tab sis nws tuaj yeem ua rau koj cov khoom puas, yog li ceev faj. Txhawm rau ua qhov kev sim no, rub koj cov kub tawm tsam ib daim ntawm cov unglazed ceramic lossis porcelain. Yog tias lub cim sab laug yog xim kub, koj daim yuav zoo li kub tiag.
Kev ntsuas kub yog dab tsi?
Qhov kev ntsuas tseeb tshaj plaws yog siv X-ray fluorescence spectrometers (XRF). Cov tshuab no, uas tuaj yeem raug nqi ntau txhiab daus las, xa X-rays los ntawm cov khoom kuaj.
