Phosphite yog tsim los ntawm qhov kub siab. Graphite feem ntau pom muaj nyob rau hauv marble, schist lossis gneiss, thiab nws yog tsim los ntawm metamorphism ntawm cov khoom siv organic carbonaceous. Coal seam tuaj yeem tsim ib feem rau hauv graphite los ntawm thermal metamorphism. Graphite yog cov mineral tseem ceeb ntawm igneous pob zeb. Graphite kuj tseem muaj nyob rau hauv meteorites. Nws feem ntau yog lumpy. Polycrystalline aggregates uas tsim ib lub cubic duab nrog ib qho kev sib raug zoo hu ua square graphite. Yog li ntawd yog vim li cas flake graphite tuaj yeem siv ua cov khoom siv sealing? Cov Furuite Graphite hauv qab no Xiaobian coj koj mus paub ntau ntxiv txog nws:
1. Tsis sib xws ntawm qhov ceev, lub zog tensile qis.
Qhov sib xws ntawm graphite muaj qhov cuam tshuam tseem ceeb heev rau qhov zoo ntawm cov phaj, cov gaskets qhov txhab thiab cov nplhaib ntim khoom.
2. Kev xeb.
Vim yog cov ntsiab lus sulfur thiab cov ntsiab lus chlorine ntawm cov graphite tseem ceeb, cov khoom sib xyaw ua ke siab dhau.
3. Tus nqi xau siab.
Vim yog cov khoom siv raw zoo, cov tshauv muaj pes tsawg leeg thiab cov thev naus laus zis ntau lawm ntawm cov graphite tseem ceeb.
