Whakaahuatanga Hua

He wheketere o ngā mata keri tricone mō te puna hinu kei roto i te taonga me te utu whakaheke.
IADC: 115 he mata porotaka hiri niho rino me te tiakitanga ine mō ngā hanganga ngohengohe me te kaha pēhi iti.
Ko ngā taipitopito o te kaha pēhi o ngā moka IADC115 e whai ake nei:
0-35 MPA/ 0-5,000 PSI
Whakaahuatanga Whenua:
He pai te mata tricone IADC115 mō ngā toka ngohengohe, kāore i te tino kiato, me ngā toka kore-papa pērā i te kōhatu marl, te tote, te gypsum, me ngā waro mārō, ngā uku me ngā onepū kāore i te tino kiato.
Kei ngā mata tricone te momo Tungsten Carbide Insert (TCI) me te Mill Tooth (Steel Tooth) e ai ki ngā rauemi tapahi.
He maha ngā whakamahinga, ā, ka taea te tapahi i ngā momo hanganga maha. Ka whakamahia te mata keri tricone niho mira mō ngā hanganga ngohengohe. Ka whakamahia ngā mata keri tricone hurihuri TCI mō ngā hanganga waenga me ngā hanganga mārō. Kei roto i ngā hanganga toka ngohengohe ngā onepū kāore i whakapūmautia, ngā uku, ngā kōhatu kōhatu ngohengohe, ngā moenga whero me te kirikiri. Kei roto i ngā hanganga waenga mārō ko ngā dolomites, ngā kōhatu kōhatu, me te kirikiri mārō, ko ngā hanganga mārō ko te kirikiri mārō, ko ngā hanganga mārō ko te kirikiri mārō, ngā kōhatu paru, ngā kōhatu kōhatu cherty me ngā hanganga mārō me ngā hanganga koi.

Te hanganga	He hanganga ngohengohe, he iti te ātete ki te kuru, he teitei hoki te āheinga ki te keri.

Mā te hanganga niho kua arotauhia ka matotoru ake te koranu ātete-kakahu o te mata niho me te hononga o runga o te niho, ka pai ake te ātete-kakahu o te niho, ka tere ake te keri miihini. He rapa te hiri o ngā wahi niho rino kia roa ai te mau me te pono. Mā te whakamahi i tētahi tukanga whakarewa hou, ka whakamahia he rauemi whakarewa hou ki ngā mata o roto, o waho hoki o ngā niho kia ātete ake ai te kakahu o ngā niho.
