Cov khoom thiab cov yam ntxwv ntawm pob zeb diamond

Ob lub pob zeb diamond thiab graphite yog carbon-based crystals, tab sis lawv cov khoom sib txawv vim lawv cov qauv sib txawv.

Hauv cov qauv pob zeb diamond, carbon atoms nyob rau hauv lub xeev tetravalent. Cov yam ntxwv tseem ceeb ntawm cov qauv pob zeb diamond yog tias txhua cov pa roj carbon atom yog sib koom ua ke rau plaub cov pa roj carbon atom nyob sib ze hauv tetrahedral cov lus qhia, uas ua rau pob zeb diamond zoo heev hardness.

Pob zeb diamond nthuav tawm ntau yam morphologies, uas yog qhov tseem ceeb rau kev nkag siab tob rau hauv cov xwm txheej thiab cov txheej txheem ntawm pob zeb diamond siv lead ua.

Lub hardness ntawm pob zeb diamond, los ntawm qhov muaj zog tshaj plaws mus rau qhov tsis muaj zog, yog nyob rau hauv qhov kev txiav txim ntawm octahedron, dodecahedron, thiab hexahedron. Zoo-tsim hexahedral thiab octahedral polyhedral cov ntaub ntawv kuj muaj zog zoo heev.

Hardness: Pob zeb diamond yog cov khoom hnyav tshaj plaws nyob hauv lub ntiaj teb. Nyob rau hauv Mohs nplai ntawm hardness, qhov twg kaum minerals ua tus qauv los txiav txim qhov muaj nuj nqis ntawm 1 mus rau 10, pob zeb diamond lub hardness yog nyob rau ntawm qhov siab tshaj plaws ntawm 10. Pob zeb diamond qhov sib txhuam coefficient nyob rau hauv huab cua yog 0.1, thiab nws hnav nws txawv heev raws li. ntawm txoj kev sib txhuam.

Pob zeb diamond muaj cov khoom siv hydrophobic thiab lipophilic, uas yuav tsum tau coj mus rau hauv kev txiav txim siab tshwj xeeb thaum lub sij hawm ntxuav pob zeb diamond kom tsis txhob poob. Ntawm qhov tod tes, siv cov emulsion raws li cov kua dej hauv qhov drilling tuaj yeem tiv thaiv cov pob zeb diamond thiab txhim kho lawv cov kev ua tau zoo.
