Impushana yedayimane yasekhaya enokuningi | uhlobo lwedayimane elilodwa le-crystal njengento eluhlaza, kodwa | thayipha okuqukethwe okuphezulu kokungcola, amandla aphansi, angasetshenziswa kuphela ekufuneni umkhiqizo wemakethe osezingeni eliphansi. Abakhiqizi abambalwa bedayimane basekhaya basebenzisa uhlobo lwe-I1 noma lwe-Sichuan uhlobo lwedayimane lekristalu elilodwa njengempahla eluhlaza ukuze bakhiqize impushana yedayimane, ukusebenza kahle kwayo kokucubungula kukhulu kakhulu kunempushana yedayimane evamile, engahlangabezana nesidingo semakethe esezingeni eliphezulu. I-Diamond powder high hardness, ukumelana nokugqokwa okuhle, isetshenziswa kabanzi ekusikeni, ukugaya, ukubhola, ukupholisha neminye imikhakha. Ngokuthuthuka nenqubekelaphambili yesayensi nobuchwepheshe, isidingo semakethe sempushana yedayimane siya ngokuba sikhudlwana, futhi nezidingo zekhwalithi ziya ngokuya ziba phezulu. Ngempushana yedayimane, inani lokungcola kumpushana wedayimane lithinta ngqo ikhwalithi yomkhiqizo nokusebenza kwempushana.
Izinhlobo ezingabazekayo
Ukungcola kwempushana yedayimane kubhekisela ezingxenyeni ezingezona ikhabhoni kumpushana wedayimane, ezingahlukaniswa zibe ukungcola kwangaphandle okuyimbudumbudu kanye nokungcola kwangaphakathi. Ukungcola kwangaphandle kwezinhlayiya kwethulwa ikakhulukazi ngezinto zokusetshenziswa kanye nenqubo yokukhiqiza, okuhlanganisa i-silicon, insimbi, i-nickel, i-calcium, i-magnesium ne-cadmium; ukungcola kwangaphakathi kwezinhlayiya kwethulwa ohlelweni lokuhlanganiswa kwedayimane, ikakhulukazi okuhlanganisa insimbi, i-nickel, i-cobalt, i-manganese, i-cadmium, ithusi, njll. Insimbi, i-nickel nokunye ukungcola kuzokwenza umkhiqizo ukhiqize amazinga ahlukene we-magnetism, ukusetshenziswa kwempushana.
, Indlela yokuthola ukungcola
Kunezindlela eziningi zokuthola ukungcola kokuqukethwe kwempushana yedayimane, okuhlanganisa indlela yesisindo, i-spectroscopy yokuphuma kwe-athomu, i-spectroscopy yokumuncwa kwe-athomu, njll., izindlela zokuthola ezahlukene zingakhethwa ngokuvumelana nezidingo ezahlukene.
ukuhlaziywa kwegravimetric
Indlela yesisindo ifanele ukuhlaziya nokutholwa kokuqukethwe kokungcola okuphelele (ngaphandle kwezinto eziguquguqukayo ezivuthayo ekushiseni okushisayo). Imishini eyinhloko ihlanganisa i-mafer furnace, ibhalansi yokuhlaziya, i-porcelain crucible, isomisi, njll. Indlela yokuhlola yokuqukethwe ukungcola ezingeni lomkhiqizo we-micropowder yindlela yokulahlekelwa ukushisa okushisayo: isampula ngokuvumelana nezinhlinzeko bese uthatha isampula yokuhlola uyifake ku-crucible enesisindo esingaguquki, beka i-crucible equkethe isampula okufanele ihlolwe esithandweni sokushisa esivunyelwe +100 esingaguquki. 20℃), isisindo esiyinsalela yisisindo esixubile, futhi iphesenti lesisindo liyabalwa.
2, i-spectrometry yokuphuma kwe-athomu, i-spectroscopy yokumuncwa kwe-athomu
I-spectroscopy ye-atomic emission kanye ne-atomic absorption spectroscopy zilungele ukuhlaziya okuseqophelweni eliphezulu nokwenani kwama-trace elements.
(1) I-spectrometry ye-atomic emission: iyindlela yokuhlaziya yokuhlaziya ikhwalithi noma ubuningi bomugqa wemisebe oyisici okhiqizwa uguquko lwe-electron lusuka emandleni angaphandle ezakhi zamakhemikhali ezihlukahlukene. Indlela yokukhipha i-athomu ivumela ukuhlaziya cishe ama-elementi angama-70. Ngokuvamile, ukukalwa kwezingxenye ezingaphansi kuka-1% kungakala ngokunembile izinga le-ppm lokulandela izici kumpushana wedayimane. Le ndlela ingeyokuqala ekhiqizwa futhi yathuthukiswa ekuhlaziyweni kwe-optical. I-spectrometry ye-atomic emission idlala indima ebalulekile ekuhlaziyweni kwekhwalithi nenani lezinto ezihlukahlukene zesimanje. Inezinzuzo zekhono lokutholwa kwezinto eziningi ngesikhathi esisodwa, isivinini sokuhlaziya okusheshayo, umkhawulo wokutholwa ophansi kanye nokunemba okuphezulu.
(2) I-spectroscopy yokumuncwa kwe-athomu: lapho imisebe ekhishwa umthombo othile wokukhanya idlula kumhwamuko we-athomu wesici okufanele ikalwe, imuncwa ama-athomu ombuso ophansi, futhi idigri yokumunca elinganisiwe ingakalwa ukuze kuhlaziywe i-elementi.
I-spectrometry yokumuncwa kwe-athomu futhi ingaphelelisana futhi ayikwazi ukushintshwa enye nenye.
3. Izinto ezithinta izilinganiso zokungcola
1. Umthelela wevolumu yesampula enanini lokuhlola
Ngokwenza njalo, kutholakala ukuthi inani lesampula lempuphu yedayimane linethonya elikhulu emiphumeleni yokuhlolwa. Uma inani lesampula lingu-0.50g, ukuphambuka okumaphakathi kokuhlolwa kukhulu; lapho inani lesampula lingu-1.00g, ukuchezuka okumaphakathi kuncane; lapho inani lesampula lingu-2.00g, nakuba ukuphambuka kukuncane, isikhathi sokuhlola siyakhula futhi ukusebenza kahle kuyehla. Ngakho-ke, ngesikhathi sokulinganisa, ukukhulisa inani lesampula ngokunganaki akuthuthukisi ukunemba nokuzinza kwemiphumela yokuhlaziya, kodwa futhi kuzonweba kakhulu isikhathi sokusebenza futhi kunciphise ukusebenza kahle komsebenzi.
2. Umthelela wosayizi wezinhlayiyana kokuqukethwe ukungcola
Uma ingxenyana yempushana yedayimane incinyane, iba nkulu ukungcola okukupowder. Usayizi wezinhlayiyana ojwayelekile ungu-3um kumpushana wedayimane ocolekile ekukhiqizeni, ngenxa yosayizi wezinhlayiyana ezinhle, enye i-asidi nesisekelo sezinto ezingancibiliki ezixutshwe ezintweni ezingavuthiwe akulula ukuzihlukanisa, ngakho-ke ihlala ibe yimpushana eyizinhlayiyana, ngaleyo ndlela ikhulise okuqukethwe kokungcola. Ngaphezu kwalokho, lapho inhle kakhudlwana usayizi kuyizinhlayiyana, kulapho inqubo yokukhiqiza, ukungcola okwengeziwe ngaphandle, ezifana dispersant, ukuxazulula liquid, imvelo ukukhiqizwa uthuli ukungcola ukungcola ocwaningweni powder isampula ukungcola test okuqukethwe, sithole ukuthi ezingaphezu kuka-95% of the emahhadla-grained diamond imikhiqizo powder, okuqukethwe ukungcola yayo ngezansi 0.50in powder imikhiqizo engaphansi kuka-0.50% inhlawulo okuqukethwe kwe-powder ngezansi kokuqukethwe ukungcola okungaphezu kuka-95%. 1.00%. Ngakho-ke, ekulawuleni izinga lempushana, impushana ecolekile kufanele ibe ngaphansi kuka-1.00%; okuqukethwe kokungcola kwe-3um kufanele kube ngaphansi kuka-0.50%; futhi izindawo ezimbili zamadesimali kufanele zigcinwe ngemva kwedatha yokuqukethwe ukungcola ezingeni. Ngenxa yokuthi ngenqubekelaphambili yobuchwepheshe bokukhiqiza i-powder, okuqukethwe kokungcola ku-powder kuzonciphisa kancane kancane, ingxenye enkulu yokungcola kwe-powder eqinile ingaphansi kwe-0.10%, uma indawo eyodwa yedesimali igcinwa, ikhwalithi yayo ayikwazi ukuhlukanisa ngokuphumelelayo.
Lesi sihloko sithathwe ku-"inethiwekhi superhard impahla"
