Kev sib tsoo log txiav cov ntu feem ntau yog siv qee qhov sib luag los nce cov xim ntawm qhov sib tsoo. Ntawm ib sab, nws yog rau kev ua kom zoo nkauj; ntawm qhov tod tes, nws tuaj yeem tiv thaiv qhov txiav ntawm qhov sib tsoo lub log thiab txhim kho lub teeb tsis kam thiab siab kub tiv thaiv ntawm qhov sib tsoo. Niaj hnub no peb yuav tham txog hom xim muaj nyob hauv kev txiav ntawm qhov sib tsoo log.
1. Cov hlau oxide liab, luv luv rau hlau liab, feem ntau hu ua Sudan, yog qhov pheej yig liab xim nrog kev zais muaj zog thiab tinting zog. Nws muaj lub teeb zoo heev tiv taus, siab kub tsis kam, tiv taus rau cov cua hauv huab cua, tiv taus cov pa paug, thiab tiv taus txhua alkalis. Vim tias cov txheej txheem kev tsim khoom sib txawv thiab cov txheej txheem sib txawv, lub xeev siv lead ua thiab cov qauv sib txawv, thiab xim thiab teeb ci ntawm kev txiav cov khoom ntawm cov hniav sib tsoo muaj qhov sib txawv. Ua tib zoo saib xyuas thaum siv nws.
2. Chrome oxide ntsuab, hu ua chrome ntsuab, xim xim qhia los ntawm kev sib tsoo log txiav tshuab chaw lag luam li ntawm ci ntsuab mus rau ntsuab tsaus. Qhov kub ua hauj, tiv taus lub teeb, tiv taus ntau cov kuab tshuaj lom neeg.
3. Cov hlau oxide dub, luv luv rau hlau dub, hmoov dub, yog tus qauv ntawm cov hlau oxide thiab ferrous oxide. Cov neeg tsim kev lag luam ntawm lub tshuab ua kom zoo nkauj ntseeg tau hais tias nws muaj qhov muag daj-dub xim, muaj zais siab zog thiab tinting zog, tab sis tsis zoo li carbon dub. Nws yog qhov ruaj khov rau hnub ci thiab huab cua, tiv taus txhua alkalis, tab sis soluble hauv acid.
4. Cov pa roj carbon dub, lub teeb thiab cov hmoov dub zoo heev, lub ntsiab tivthaiv yog cov pa roj carbon dub, muaj cov pa oxygen, hydrogen, sulfur, thiab lwm yam.
5. Titanium dioxide, feem ntau hu ua titanium dioxide lossis titanium dioxide, hmoov dawb, yog cov xim dawb nrog lub zog tinting muaj zog. Cov neeg tsim khoom ntawm kev sib tsoo cov log txiav ntseeg tias nws muaj zoo zais zog thiab xim nrawm nrawm, zoo lub teeb zoo, thiab tsis muaj tshuaj lom.
