1. Kev tshuaj xyuas qhov tshwm sim
Qhov zoo ntawm cov txhuam hniav tuaj yeem raug txiav txim ua ntej los ntawm kev tshuaj xyuas qhov muag. Ua ntej ntawm tag nrho cov, xyuas seb qhov chaw ntawm cov pa roj carbon txhuam yog qhov sib xws, seb puas muaj qhov tsis sib xws, npuas, tawg thiab lwm yam tsis xws luag. Qhov thib ob, nws yog ib qho tsim nyog los xyuas seb qhov luaj li cas ntawm cov txhuam hniav ua tau raws li qhov yuav tsum tau ua, tshwj xeeb tshaj yog seb qhov ntev thiab txoj kab uas hla ntawm cov txhuam hniav yog txuam nrog lub tshuab. Thaum kawg, xyuas seb cov xim ntawm cov txhuam hniav puas zoo ib yam, vim cov xim sib txawv yuav ua rau qhov sib txawv ntawm cov txhuam hniav thiab qhov sib txawv.
2. Kev sim hardness
Hardness yog ib qho ntawm cov cim tseem ceeb los ntsuas qhov zoo ntawm cov txhuam hniav. Qhov siab dua qhov hardness, qhov ntau dua qhov ceev, qhov zoo dua qhov conductivity, thiab lub neej ntev ntawm cov roj carbon txhuam. Peb tuaj yeem ntsuas qhov nyuaj ntawm cov txhuam hniav nrog lub hardness tester uas ua tau raws li qhov yuav tsum tau ua, feem ntau qhov nyuaj ntawm cov txhuam hniav yog nyob nruab nrab ntawm 5-8HRA.
3. Kev ntsuas kev coj ua
Hluav taws xob conductivity yog lwm qhov taw qhia tseem ceeb, thiab peb tuaj yeem siv multimeter los ntsuas cov conductivity ntawm carbon txhuam. Ua ntej clamp cov pa roj carbon txhuam nyob rau hauv qhov kev xeem clip ntawm lub multimeter raws li txoj kev teev tseg, thiab tom qab ntawd txuas cov ntawv xeem cwj mem mus rau ob qho kawg ntawm cov txhuam hniav, yog tias cov txhuam txhuam txhuam zoo zoo, tus nqi ntawm multimeter yuav hloov pauv hauv qhov ib txwm muaj, yog tias tus nqi siab tshaj qhov kev hloov pauv ib txwm, nws txhais tau hais tias cov khoom siv ntawm cov pa roj carbon txhuam tsis zoo.
Plaub, tiv thaiv hnav kom pom
Cov txhuam hniav txhuam txhuam ntau heev thaum siv, yog li hnav tsis kam yog lwm qhov ntsuas los ntsuas. Peb tuaj yeem siv tus ntsuas kev puas tsuaj los ntsuas qhov hnav tsis kam ntawm cov txhuam hniav. Thaum lub sij hawm xeem, cov txhuam hniav yog muab tso rau hauv cov khoom siv tester raws li cov txheej txheem, thiab tom qab ntawd qhov kev ntsuam xyuas hnav yog nqa tawm. Tom qab kev sim, koj tuaj yeem soj ntsuam qhov hnav thiab tsim kua muag ntawm cov txhuam hniav los txiav txim nws lub peev xwm los tiv thaiv kev hnav.
