Kev Piav Qhia Luv:

Graphitized Petroleum Coke HS Code 3801100090 yog hais txog graphitized carburizer. Nws yog hais txog cov khoom carbon uas nws cov qauv molecular tau hloov pauv los ntawm qhov kub siab lossis lwm txoj hauv kev. Hauv qhov kev npaj no, qhov sib nrug molecular ntawm carbon yog dav dua. Nws yog qhov zoo dua rau kev rhuav tshem nucleation hauv cov hlau kua lossis cov hlau kua. Graphite carburizer feem ntau yog siv hauv hluav taws xob cua sov melting kom tau txais cov hlau zoo dua los ntawm carburizing nrog cov hlau npua tsawg lossis txawm tias xoom tus nqi.
