Umbhalo wokufunda ngokukhula kwe-Diamond kuKudrillwa kweEngineered Quartz

Ukuchaza Ukukhula kwe-Diamond: Ukukhanda, Ukubulala, kanye nesithunzi seCrystal kumaQuartz Applications

Xa kusenza izinkulungwane zokudweba, ubunzima bezinduku zediamondi buqinisekiswa yizinto ezintathu eziphatha kakhulu: ubunzima bokuthinta okuphakeme kakhulu, ukwesaba kokuthunjwa xa kuthintelwa, nokuba yini ubuso bekristali buqinisekile. Kumaquartz engineered okungenani kabusha 93% silica noma Mohs hardness rating ye-7, izinduku zediamondi kufuneka zibe nzima kakhulu. Kufuneka zibe ne-HV engaphezu kuka-10,000 kumgaqo kaVickers futhi zilinde amandla okugaywa aphezu kuka-18 GPa ukuze kube lula ukubamba izinhlangothi zokugaya ngexesha lokusebenza. Kusobala nini xa kusebenzisa izinduku ezincane? Ubuso bekristali obungahle buvela kuzinkinga ezincane xa kuthintelwa yizindlela eziphinda phindiwe phakathi kuka-20 kuya ku-40 kN xa kudweba kumaquartz. Lezi ziphazamiso zihlukene ngexesha, lokhu kusho ukuthi izixhamo zibeka kancane kancane futhi azikwazi ukudlala njengaleyo xa ziqeqeshelwa yizinduku eziphumelelayo.

Kungani Ubunzima Bekhodi YeDiamond Yenzelwe Buqinisekile Ekudwebeni Kwamaquartz Engineered Anegesi Elinganiselwe

Xa kufika ekusebenziseni kwesikhombisa, izidimantayi ezinzulu zibangela ukuthi izindlu zize ngaphezulu ngenkathi yizinsuku ezingama-30% ngokwengeziwe ngokuthi kuzothuthwa kakhulu kuzo izimo zezinsuku ze-tetrahedral. Abafana bezemvelo bavala lezi zi-diamonds ze-High Pressure High Temperature (HPHT) abazifundile futhi bazifundile okuthile okuthakathaka. Lezo ngezinkinga ezingaphansi kuka-5% zazisebenza kahle emuva kwezinkolelo ezingaphezu kuka-1,200 kumalithi atholakala ngokufanayo no-Caesarstone, ngelixa izidimantayi zezinhlobo eziphuthumayo zazigcina phansi ngasendaweni ya-800. Kungani lokhu kudingeka? Izindlela zomlando oziningi kulezi zidimantayi ezinzulu zizisiza ukuthi zilinde kude kulezi ndawo enobuthako obunzima. Sengiyekela, izinkukho lapha zingafinyelela ukuthi kuzothutha kakhulu kuma-600 degrees Celsius xa kusebenziswa, okuzoyeka kakhulu kwezinye izinto.

Kunjani izidimantayi ezingenalo umphakathi zibaluleka ukuthi kuqokeke, kube khathulula, nokwethulwa kwezindlela zokugcina

Izidimantayi ezingenalo umphakathi—ezinezinkinga zangaphakathi noma izidingo ezingafani—zalungisa izimo ezimbili ezikhethekileyo:

1. Ukuglazela kwezimali : Ukukhuphuka kwezimali engapheli, ekhona kakhulu kumadimanthe angaphansi kuka-95% yokupheli, akhiwa ngobomi bengqondo yeglasini kuzindiza zokugcina, ukwakha umshiko ngama-40%.
2. Ukuphulula kwegunya lematrix : Umjikelezo othambile wamadimanthe uphulula igunya le-nickel-cobalt, ukusabalala kwezigunya ezingu-15–20% xa kugcwalwa iqorha elibuthayo.

Isifundo saseNyakeni 2023 esenzelwe kwiindlela ezingu-2,500 ze-quartz ezenziweyo kwabonisa ukuthi izigubha zokugcina ezisebenzisa amadimanthe aqinisiswa ngu-ASI-500 zazikhipha hhayi kangakanani kakhulu ngokungu-0.023 mm ngasinye isigubha, ngelixa amagrade angaqinisiswa azikhuphe kakhulu ngama-3.2 ngokushesha. Lokhu kukhuphuka okusheshayo kubangela izindleko—izigubha ezinzima ngaka-0.1 mm ezenza izindleko ezingaphezu kuka-$18.50 ngasinye isigubha.

Ukufakelana Kwesilinganiso SikaDiamanti Nezimali ZeQuartz Ezakhiwe

Iququla eziginiweyo—ebantwana kwi-90–95% yomthuthi ocothulunywa obekwe ngama-5–10% amapolymer resins—iyaphakamisa izinkinga ezihlukileyo yokudweba. Ukuchithwa kwalo okuphezulu (7–7.5 Mohs) nokuthuthwa kwegesi kufuna ubumfangela bethengelelo nezibonakaliso zokudweba ziqhathanise ngcono ukuze kugcinwe ukubanjwa okuhle nokucophele.

Ukuzifunda Kwizici Zomthelela WaseQubeni Nezingeka Ezivela Kukudweba

Umqhele wama-silica ubalulekile lapha, ngakho kudinga ama-diamond atholakala nempilo engaphezu kwamandla ngaphandle kokuba amandla avuthiwe kakhulu. Ngokwesibini, umkhondo wesinze wasezantsi awuhlazi kangaka, okushintsha indlela ethile amadiyamani ihlala isebenzisa khona ku whatever ikhakhaniswa nawo. Xa ukubhola ngaloo zinto, kukhona isilinganiso esingcolile phakathi kokuqeda okwaneleyo ukuze uhlehlise le ziqhamo ze-quartz futhi usabeke kube khona ukuthula okuphumelelayo ekulawuleni indlela isinze ibuyela emva kokuthathwa kwayo. Lokhu kungcwele yindlela ifracture toughness iyaphila kakhulu kulula kwebhodiya ezigxileni. I-diamond engeyiyo yizinyo ezingagcina angakaphila kade kakhulu ukuze inike imfundo engcono.

Ukuthunyaniswa Kwegunya Lomkhondo we-Diamond Nezilinganiso Zomthelelo

Ubuchwepheshe besidinga kufanele kube yisimo esifanayo nesimo sesiqhamo sethu. Izingxenye ezisebenzisa ikhobhamu zisebenza kahle kakhulu emibhalobheni enobukhulu (kune-93%) ngokugcina ukugcinwa kwezindikima ngapha kwebhuluki elikhulu. Izingxenye ezisebenzisa i-iron zihle kakhulu kumibhalobhe enobukhulu obuncane, nezibambisana ngaphakathi. Ukungcubana kwesidinga kakhulu kuchitha isahluko nge-18–22% emibhalobheni enezibambisana ngaphakathi, njengoba kuboniswa emsebenzini wamagaka.

Isibonelo: Ukuphazanyiswa Kusivimba Ngeminyaka Engaphansi Yezindikima Ezinezibambisana Ngaphakathi

Kuqala kwi-2023, abasebenzi basebenzisa izixhumanisi ezimbili eziphambene zomkhonto we-diamond we-10mm emanzini yezibuko ezenza kuyo sileka eqenjini eliphindwe kabini ngo-80% silica nangaphakathi kwezibuko ezingaphindwanga kabini ngo-20% resin binder. Ibit enkulu ebakhetyiwe ngodonga lwamadimanthe angama-100/120 US mesh ihlala ineminyaka engama-320 ngomzuzu kumgqa ophakeme kwezibuko ezingama-38 ezenziwa ngokuphindaphindi. Ngokwesinye isikhathi, xa kuchazwa umahluko wendalo yokunciphisa okunikezwe kudonga olungcolileyo olunezidingo ezingaphindwanga kabini (80/100 mesh), izinto azizange zilungele. Emva kokugcwalisa kuphela izibuko ezingama-12, isivikelo sesilinganiso samandla asiphindwanga kabini sihlatshelwa ku-210 RPM ngoba amadimanthe amaningi kakhulu ayekhululwa kumatrix wakhe ngexesha lokusebenza. Xa sibheke ngakumbi ukuthi kutheni kwakukhona umehluko mkhulu, kubonakalayo ukuthi kutheni kwakukhona umehluko mkhulu. Izicwangciso zibonisa ukuthi le daimanthe encintisayo yayinezinkinga eziphindwe kabini (ngaphezu kuka-40%) ngaphantsi kwezidingo, okwakhiqiza ukucindezelwa kusuku olunxulumene nomgca womgca wamathambo ethu ekugcineni kuthi kube nenkinga enkulu kumgca wosuku.

Lokhu kubonisa ukuthi ubunzima beemvelo nekungqimba okufanele kwe-bond kubaluleke kakhulu. Izigaba ezingezantsi zihlukana ngokuxhasa emisebenzini yomlando, ekhathazeka kakhulu izindleko zomsebenzi.
