1. Kev yuav khoom
1. Nkag siab cov qauv ntawm cov cuab yeej fais fab: Cov cuab yeej hluav taws xob sib txawv muaj cov qauv sib txawv ntawm cov pa roj carbon txhuam thiab qhov ntau thiab tsawg, yog li peb yuav tsum nkag siab cov qauv thiab hom ntawm peb cov cuab yeej fais fab, thiaj li xaiv cov pa roj carbon txhuam kom zoo.
2. Carbon txhuam zoo: Thaum muas cov txhuam hniav, xyuam xim rau cov teeb meem zoo. Feem ntau hais lus, cov khoom siv roj carbon zoo yuav tsum tau ua los ntawm cov rosin ntshiab, uas tuaj yeem lav hnav tsis kam thiab hluav taws xob conductivity.
3. Kho kom raug: Thaum xaiv cov txhuam hniav, koj yuav tsum tau xyuam xim rau qhov sib txawv ntawm sab laug thiab sab xis, thiaj li tsis txhob cuam tshuam rau lawv, thiab sab laug thiab sab xis yog symmetrical, thiab ib qho hnav tawm, koj yuav tsum tau hloov. ob sab tib lub sijhawm.
2. Kev daws teeb meem rau cov teeb meem tshwm sim
1. Carbon txhuam hnav: Thaum siv ntev heev, cov txhuam hniav yuav tsum tau hloov vim hnav thiab tsim kua muag. Feem ntau hais lus, qhov ntev ntawm cov txhuam hniav yuav tsum nyob ib ncig ntawm 5-6mm. Yog tias qhov ntev tsawg dua 3-4mm, ces cov txhuam hniav yuav tsum tau hloov tam sim ntawd.
2. Cov pa roj carbon txhuam arc tshwm sim: Thaum siv cov cuab yeej hluav taws xob, yog tias cov pa roj carbon txhuam arc tshwm sim hnyav, nws yuav ua rau muaj teeb meem xws li cua sov thiab suab nrov ntawm cov cuab yeej hluav taws xob. Lub sijhawm no, nws yog ib qho tsim nyog los xyuas seb cov txhuam hniav puas tau nruj thiab hloov cov txhuam hniav uas hnav.
3. Cov txhuam hniav uas nruj dhau los yog xoob dhau: Thaum cov txhuam hniav raug ntsia nruj dhau los yog xoob dhau lawm, yuav muaj teeb meem. Thaum txhim kho cov pa roj carbon txhuam, qhov nruj yuav tsum tau ua tib zoo kho kom tsis txhob cuam tshuam rau kev siv cov cuab yeej hluav taws xob ib txwm muaj.
