Q: Koj puas poob nyiaj ntau npaum li cas thaum koj yaj nws?
A: Feem ntau, thaum melting kub, koj tuaj yeem cia siab tias qhov poob ntawm ib ncig ntawm 0.1 - 1%. Qhov kev poob no, hu ua "melt poob," tshwm sim feem ntau vim yog impurities hlawv tawm thaum lub sijhawm melting. Piv txwv li, yog tias muaj me me ntawm lwm cov hlau alloyed nrog cov kub los yog cov kab mob saum npoo av, lawv yuav raug tshem tawm thaum kub mus txog nws qhov melting point. Tsis tas li ntawd, ib qho me me ntawm cov kub yuav poob rau hauv daim ntawv ntawm vaporization ntawm qhov kub thiab txias, txawm tias cov khoom siv melting niaj hnub no yog tsim los txo qhov no. Txawm li cas los xij, qhov tseeb ntawm qhov poob tuaj yeem sib txawv nyob ntawm qhov purity ntawm qhov pib kub, cov txheej txheem melting siv, thiab kev ua haujlwm ntawm cov khoom siv. Los ntawm lub tshuab nqus tsev melting, nws tau kho li xoom poob.
Shenzhen Hasung Precious Metals Equipment Technology Co., Ltd. yog ib lub tuam txhab tsim khoom siv tshuab nyob rau sab qab teb ntawm Suav teb, hauv lub nroog zoo nkauj thiab loj hlob sai tshaj plaws hauv kev lag luam, Shenzhen. Lub tuam txhab yog ib tus thawj coj hauv kev siv tshuab hauv thaj chaw ntawm cov khoom siv cua sov thiab casting rau cov hlau muaj nqis thiab kev lag luam khoom siv tshiab.
Peb txoj kev paub txog kev siv tshuab nqus tsev ua rau peb pab tau cov neeg siv khoom lag luam los ua cov hlau uas muaj cov hlau sib xyaw ua ke ntau, cov hlau platinum-rhodium uas xav tau cov hlau nqus tsev ntau, kub thiab nyiaj, thiab lwm yam.
