Tsis muaj kev tshem tawm cobalt; tag nrho cov txheej pob zeb diamond khaws cov cobalt. Lawv pheej yig dua tab sis tsis muaj kev ruaj khov thermal, tsuas yog tsim rau cov qhov dej ntiav, qis dua 500 ° C) nrog cov pob zeb mos, tsis abrasive.
Kev Nkag Siab Tseem Ceeb: As Tus Kws Kho Qhov Drillingcov lus qhia, cov txiav uas tsis tau ntxuav ua haujlwm sai dua 3 zaug dua li cov uas tau ntxuav tob hauv qhov chaw kub siab—qhov kev txiav txim siab tseem ceeb rau cov neeg khawb av Nigerian ua haujlwm hauv cov qhov roj tob.
Kev Sib Piv Kev Ua Tau Zoo: Deep Leached vs Non-Leached Wholesale Pcd Cutters
Pab cov neeg ua haujlwm Nigerian xaiv qhov yogCov Tshuab Txiav Pcd Lag Luam Wholesale, peb tau piv cov kev xaiv uas tau nqus dej tob thiab cov uas tsis tau nqus dej los ntawm plaub tus neeg muab khoom saum toj kawg nkaus—xws li Ninestones Superabrasives—tsom mus rau cov ntsuas uas tseem ceeb tshaj plaws hauv Nigerian formations:
Kev ntsuas
Sib sib zog nqus (Ninestones)
Tsis-Leached (Generic)
Kev Ruaj Ntseg Thermal
Tiv taus graphitization txog li 1100 ° C
Tsis ua haujlwm ntawm 650 ° C
Kev Tiv Thaiv Hnav
92%+ pob zeb diamond ntim, kav ntev dua 2.5 npaug
Glazes sai sai, qeeb ROP
Kev Siv Nyiaj Tau Zoo
Tus nqi tag nrho qis dua mus sij hawm ntev
Pheej yig dua 20–30% ua ntej, kim dua 40% rau lub sijhawm ntev
Ninestones sawv tawm los ntawm kev muab ob qho tib si zoo tshaj plaws deep leached thiab non-leached.Cov Tshuab Txiav Pcd Lag Luam Wholesale, tsim los rau Nigeria cov xwm txheej khawb av sib txawv - los ntawm cov av nplaum qis mus rau cov xuab zeb tob thiab kub.
Cov Ntaub Ntawv Teb: Cov Tshuab Txiav Pcd Lag Luam Wholesale Deep Leached hauv Niger Delta
Ib tug neeg ua haujlwm roj Nigerian hauv Niger Delta tau sim cov roj uas tau nqus tob (Ninestones) thiab cov roj uas tsis tau nqus (generic).Cov Tshuab Txiav Pcd Lag Luam Wholesalenyob rau hauv lub qhov dej tob 4,500m (qhov kub hauv qab 820 ° C, xuab zeb abrasive):
Tsis-Leached (Generic)
Ua tsis tiav tom qab7 teev
Kev pom ntawm thermal graphitization
4 qhov kev hloov pauv cuab yeejxav tau
Tag nrho lub sijhawm khawb av:45 teev
Sib sib zog nqus (Ninestones)
Khiav24 teevnrog xoom thermal failure
Tsuas yog1 qhov kev hloov cuab yeejxav tau
Tag nrho lub sijhawm khawb av:28 teev (sai dua 38%)
Tus nqi cuab yeej qis dua 52%vs tsis muaj dej ntws
"Ninestones cov cuab yeej txiav Pcd lag luam wholesale uas tau ntxuav tob tob yog qhov hloov pauv zoo rau peb cov qhov dej tob. Lawv tswj tau qhov kub thiab kev sib txhuam zoo dua li lwm hom - peb tau txo lub sijhawm tsis ua haujlwm ntau dua ib nrab."
