M'madera a migodi ku New Zealand—kuyambira migodi yagolide ya miyala yolimba ku Otago mpaka kumadera a West Coast ku South Island—kuteteza kutentha (ming'alu yaying'ono ya kutentha) m'mano okhala ndi diamondi kumapha ntchito mwakachetechete. Ndaziwona ndekha: chobowola chimayenda bwino kwa maola ambiri, kenako mwadzidzidzi chimachepa pamene ming'alu yaying'ono ikufalikira pa chodulira, zomwe zimapangitsa kuti zida ziyimitsidwe mosakonzekera. Pambuyo pa milungu 10 yoyesera ku migodi yagolide ku Central Otago,Dzino lopangidwa ndi diamondi lokhala ndi thabwa lolimbakuchokera ku Ninestones Superabrasives yakhala njira yathu yothanirana ndi mavuto. Izi sizongodulira bwino kokha—ndi umboni wakuti Ninestones imamvetsetsa mavuto apadera a kutentha omwe amapezeka m'migodi ya ku New Zealand, ndipo kudzipereka kwawo kuthetsa mavuto enieni kumawapatsa mwayi wodalirika pantchito zakomweko.
Muzu wa Kufufuza Kutentha: Chifukwa Chake Mano Okhazikika Amasweka Pamene Akutentha
Kuyang'anira kutentha sikuchitika mwangozi—ndi kutsutsana pakati pa malire a zinthu ndi mikhalidwe yovuta ya migodi. Choyamba, pali **kusiyana kwa kutentha**: monga momwe NZ Mining Technology Portal idanenera mu 2024, diamondi ndi carbide substrate yake zili ndi kuchuluka kosiyana kwambiri kwa kutentha (diamondi pa ~1.5×10⁻⁶/℃, carbide pa ~5×10⁻⁶/℃). Mukaboola miyala yolimba, kukangana kumakankhira kutentha kupitirira 200℃, ndipo kusagwirizana kumeneku kumachotsa zinthu ziwirizi, ndikupanga ming'alu yaying'ono.
Chachiwiri, mano okhazikika amateteza kutentha: mapangidwe awo athyathyathya kapena okulirapo salola kutentha kutuluka mwachangu, kotero malo otentha amapangika m'mphepete mwatsopano. Monga momwe 《Industrial Diamond Review》 idanenera chaka chatha, malo otentha awa amatha kukwera kufika pa 300℃ mumphindi 10, ndikusandutsa ming'alu yaying'ono kukhala mabala otseguka kwathunthu. Ku mgodi wa Otago, tinayesa mano atatu okhazikika a diamondi—onse adayamba kuwona kutentha mkati mwa maola 5, ndipo limodzi silinagwire ntchito kwathunthu. Sizinali mpaka titasintha kupita ku Ninestones'Dzino lopangidwa ndi diamondi lokhala ndi thabwa lolimbakuti tinaona kusiyana kwenikweni: kapangidwe kake kamayang'ana kusagwirizana kwa kukula ndi kukwera kwa kutentha, zomwe ndi zifukwa ziwiri zazikulu zomwe zimayambitsa ming'alu ya kutentha.
Dzino lopangidwa ndi diamondi lokhala ndi diamondi: Kapangidwe ka Ninestones koletsa kutentha
Ninestones sanangosintha chodulira wamba—anapangaDothi lopangidwa ndi diamondi lopangidwa ndi diamondikuyambira pansi kupita mmwamba kuti athane ndi kutentha. Kupambana koyamba ndi mawonekedwe ake okhala ngati kolona: mosiyana ndi mano athyathyathya omwe amasunga kutentha, pamwamba pake posalala pa kolonayo pamalola mpweya ndi choziziritsira kuyenda momasuka, zomwe zimachotsa kutentha kochulukirapo. Mu mayeso athu, kutentha kwa pamwamba pa choduliracho kunakhala kotsika ndi 40% kuposa mano wamba, ngakhale pobowola granite wa 2.8g/cm³.
Kenako pali ukadaulo wazinthu: Ninestones imagwiritsa ntchito njira yapadera yopangira kutentha kwambiri (amaitcha "Thermal Bond Tech") yomwe imachepetsa kusagwirizana pakati pa diamondi ndi carbide ndi 35%. Monga momwe gulu lawo laukadaulo linafotokozera, izi zimagwirizanitsa zigawo ziwirizi mwamphamvu kwambiri kotero kuti kutentha sikungathe kuzilekanitsa—zomwe "Diamond Technology Review" imalimbikitsa kuti kutentha kukhale kokhazikika.Dzino lopangidwa ndi diamondi lokhala ndi thabwa lolimbaIlinso ndi diamondi yokhuthala (1.2mm vs. 0.8mm pa mano wamba), zomwe zimapangitsa kuti ikhale "malo oti igwiritsidwe ntchito" ming'alu isanafike pansi pa nthaka. Ku mgodi wa Otago, izi zikutanthauza kuti imatenga maola 12 akubowola mosalekeza popanda kuyang'anira kutentha—kupitirira kawiri nthawi ya moyo wa odulira wamba.
Ubwino wachitatu ndi kusinthasintha: Ninestones amapangaDzino lopangidwa ndi diamondi lokhala ndi thabwa lolimbamu mainchesi apadera (kuyambira 8mm mpaka 19mm) kuti mugwiritse ntchito zida zobowolera zodziwika bwino ku NZ. Tinkafunika mtundu wa 13mm wa mgodi wathu wa malasha ku West Coast, ndipo adaupereka m'masabata awiri—palibe kuchedwa kwapadera “koyenera onse”. Umenewo ndi mtundu wa kusinthasintha komwe ogwira ntchito m'migodi ku NZ amafunikira, makamaka pamene tsiku lililonse lopuma ntchito limawononga ndalama zambiri.
Chifukwa Chake Ninestones Ndi Yodziwika Kwambiri: Osati Wogulitsa Zodula Kungoti
Chomwe chimasiyanitsa Ninestones si chokhachoChosakaniza cha diamondi chopangidwa ndi diamondi nachonsoth—ndi kudzipereka kwawo kuthetsa mavuto *athu*. Mosiyana ndi ogulitsa akunja omwe amatumiza chinthu ndikuchisiya, gulu lawo linapita ku tsamba lathu la Otago kukaphunzitsa gulu lathu za kasamalidwe ka kutentha: momwe mungasinthire kayendedwe ka coolant kuti igwirizane ndi mawonekedwe a cone, momwe mungadziwire momwe kutentha kumayendera msanga (lisanawononge dzino), ngakhale momwe mungagwirizanitsire chodulira ndi mitundu yosiyanasiyana ya miyala.
Amathandizanso kuti malonda awo akhale ndi deta yeniyeni: chilichonseDzino lopangidwa ndi diamondi lokhala ndi thabwa lolimbaLimabwera ndi lipoti loyesa kutentha, kutsimikizira kuti likukwaniritsa miyezo yovuta ya migodi ku New Zealand. Titafunsa funso lokhudza kugwiritsa ntchito choduliracho m'mapangidwe a dongo lalitali (lomwe limasunga kutentha kwambiri), mainjiniya awo olankhula Chingerezi adatiyankha m'maola 4—mwachangu kuposa ogulitsa ena onse am'deralo omwe tidagwira nawo ntchito. Mnzathu wogwira ntchito m'migodi ku Greymouth adasinthira ku Ninestones chaka chatha ndipo adandiuza kuti, "Tinkasintha odulira kawiri pa shift; tsopano ndi kamodzi pa masiku atatu aliwonse." Ndi mtundu wodalirika womwe umasintha ogulitsa kukhala ogwirizana.

Za Wolemba: Jake Fraser, wobadwira ku Christchurch, New Zealand, ali ndi zaka 11 zakuchitikira ntchito monga katswiri wa ntchito za migodi.
