Iimpawu zobuchwephesha bezinga eliphezulu le-diamond ye-powder powder ibandakanya ukusabalalisa ubungakanani be-particle, i-particle shape, ukucoceka, iipropati ezibonakalayo kunye nezinye izilinganiso, ezichaphazela ngokuthe ngqo umphumo wesicelo sayo kwiimeko ezahlukeneyo zoshishino (ezifana nokupolisha, ukugaya, ukusika, njl.). Ezi zilandelayo zezona zalathisi zingundoqo zobugcisa kunye neemfuno ezihlelwe ngokweziphumo zophando ezibanzi:
Ukuhanjiswa kobungakanani besuntswana kunye neeparamitha zokulinganiswa
1. Uluhlu lobungakanani besuntswana
Ubungakanani besuntswana ledayimane yomgubo omncinci udla ngokuba yi-0.1-50 microns, kwaye iimfuno zobungakanani besuntswana ziyahluka kakhulu kwiimeko ezahlukeneyo zesicelo.
Ukupholisha: Khetha i-micron ye-0-0.5 ukuya kwi-6-12 micron yomgubo omncinci ukunciphisa imikrwelo kunye nokuphucula umphezulu ogqityiweyo 5
Ukugaya: I-Micro-powder ukusuka kwi-5-10 microns ukuya kwi-12-22 microns ifaneleke ngakumbi ekusebenzeni kakuhle kunye nomgangatho ophezulu.
Ukugaya kakuhle: I-20-30 micron powder inokuphucula ukusebenza kakuhle
2. Ubungakanani bosasazo lwesuntswana
I-D10: ubungakanani be-particle ehambelanayo ye-10% yokusabalalisa okuqokelelweyo, okubonisa umlinganiselo weengqungquthela ezintle. Umlinganiselo weengqungquthela ezintle kufuneka ulawulwe ukuze ugweme ukunciphisa ukusebenza kakuhle kokugaya.
I-D50 (i-diameter ephakathi): imele umlinganiselo we-particle size, eyona iparameter engundoqo yokusabalalisa ubungakanani be-particle kwaye ichaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokuchaneka.
I-D95: ubungakanani be-particle ehambelanayo ye-95% yokusabalalisa okuqokelelweyo, kunye nokulawula umxholo weengqungquthela ezinqabileyo (ezifana ne-D95 ezigqithisa umgangatho kulula ukubangela imikrwelo kwi-workpieces).
I-Mv (i-volume avareji yobungakanani besuntswana): ichatshazelwa kakhulu ngamasuntswana amakhulu kwaye isetyenziselwa ukuvavanya ukuhanjiswa kwesiphelo esirhabaxa.
3. Inkqubo esemgangathweni
Imigangatho yamazwe ngamazwe esetyenziswa ngokuqhelekileyo iquka i-ANSI (umz. D50, D100) kunye ne-ISO (umz. ISO6106:2016).
Okwesibini, imilo yamasuntswana kunye neempawu zomhlaba
1. Iiparamitha zemilo
Ukujikeleza: i-roundness isondele kwi-1, i-spherical ngakumbi i-particles kwaye ingcono i-polish effect; amasuntswana anoburharha obuphantsi (iikona ezininzi) zifaneleke ngakumbi kwiisarha zocingo lwe-electroplating kunye nezinye izigcawu ezifuna imiphetho ebukhali.
Iincinci ezinjenge-Plate: iinqununu ezine-transmittance> 90% zithathwa njenge-plate-like, kwaye umlinganiselo kufuneka ube ngaphantsi kwe-10%; amasuntswana afana nepleyiti ngokugqithisileyo aya kukhokelela ekuphambukeni kokubonwa kobungakanani besuntswana kunye nesiphumo sosetyenziso esingazinzanga.
Amasuntswana afana ne-bead: ubude ukuya kububanzi be-particle> 3: 1 kufuneka ilawulwe ngokungqongqo, kwaye umlinganiselo akufanele udlule i-3%.
2. Indlela yokubona imilo
Imicroscope yamehlo: ilungele ukujonga imilo yamasuntswana angaphezulu kwe-2 microns
Ukuskena i-electron microscope (SEM): isetyenziselwa ukuhlalutya i-morphology yamasuntswana e-ultrafine kwinqanaba le-nanometer.
Ukulawulwa kobunyulu nokungcola
1. Umxholo wokungcola
Ukucoceka kwedayimani kufuneka kube> 99%, kwaye ukungcola kwesinyithi (okufana nentsimbi, ubhedu) kunye nezinto ezinobungozi (isulfure, iklorine) kufuneka zilawulwe ngokungqongqo ngaphantsi kwe-1%.
Ukungcola kwemagneti kufuneka kube sezantsi ukunqanda umphumo we-agglomeration ekucoceni okuchanekileyo.
2. Ukuchaphazeleka kwemagneti
Idayimani yococeko oluphezulu kufuneka isondele kwi-non-magnetic, kwaye ukuchaphazeleka okuphezulu kwemagneti kubonisa ukungcola kwesinyithi okushiyekileyo, ekufuneka kubonwe ngendlela yokufakelwa kombane.
Iimpawu zokusebenza komzimba
1. Ukuqina kwempembelelo
Ukuchasana nokutyumza kweengqungquthela kubonakaliswe ngezinga elingapheliyo (okanye amaxesha aqhekekileyo) emva kovavanyo lwempembelelo, oluchaphazela ngokuthe ngqo ukuqina kwezixhobo zokugaya.
2. Ukuzinza kwe-thermal
Umgubo ococekileyo udinga ukugcina uzinzo kwiqondo lokushisa eliphezulu (elifana ne-750-1000℃) ukuphepha ukubunjwa kwegraphite okanye i-oxidation ebangela ukunciphisa amandla; uhlalutyo oluqhelekileyo lwe-thermogravimetric (TGA) ukufumanisa.
3. Ubulukhuni obuncinci
I-microhardness ye powder yedayimane ifikelela kwi-10000 kq / mm2, ngoko ke kuyimfuneko ukuqinisekisa amandla amasuntswana aphezulu ukugcina ukusebenza kakuhle kokusika.
Iimfuno zokuguquguquka kwesicelo 238
1. Ibhalansi phakathi kokuhanjiswa kobungakanani besuntswana kunye nesiphumo sokusebenza
Iingqungquthela ezinqabileyo (ezifana ne-D95 ephezulu) ziphucula ukusebenza kakuhle kokugaya kodwa zinciphisa ukugqitywa kwendawo: iincinci ezincinci (i-D10 encinci) zinefuthe elichaseneyo. Lungisa uluhlu lolwabiwo ngokweemfuno.
2. Ukulungelelanisa imilo
I-block multi-edge particles ifanelekile kwi-resin grinding wheels; amasuntswana angqukuva alungele ukupolisha ngokuchanekileyo.
Iindlela zokuvavanya kunye nemigangatho
1. Ukubona ubungakanani besuntswana
I-Laser diffraction: isetyenziselwa ngokubanzi i-micron / submicron particles, ukusebenza okulula kunye nedatha ethembekileyo;
Indlela yeSieve: isebenza kuphela kwiinqununu ezingaphezulu kwe-40 microns;
2. Ukubona ubume
Umhlalutyi womfanekiso wesuntswana unokulinganisa iiparitha ezifana ne-sphericity kunye nokunciphisa impazamo yokuqwalaselwa kwencwadi;
Shwankathela
Umgangatho ophezulu we-diamond micro-powder idinga ulawulo olubanzi malunga nokusabalalisa ubungakanani be-particle (D10 / D50 / D95), i-particle shape (umjikelezo, i-flake okanye umxholo wenaliti), ukucoceka (ukungcola, iimpawu zamagnetic), kunye neempawu ezibonakalayo (amandla, ukuzinza kwe-thermal). Abavelisi kufuneka bakhulise iiparamitha ngokusekwe kwimiba ethile yosetyenziso kwaye baqinisekise umgangatho ongaguqukiyo ngokusebenzisa iindlela ezifana ne-laser diffraction kunye ne-electron microscopy. Xa ukhetha, abasebenzisi kufuneka baqwalasele iimfuno ezithile zokucubungula (ezifana nokusebenza kakuhle kunye nokugqiba) kwaye batshatise izikhombisi ngokufanelekileyo. Umzekelo, ukupolisha okuchanekileyo kufuneka kubeke phambili ulawulo lwe-D95 kunye nokungqukuva, ngelixa ukugawula okurhabaxa kunokuphumza iimfuno zemilo ukuphucula ukusebenza kakuhle.
Lo mxholo ungasentla ucatshulwe kuthungelwano lwemathiriyeli enzima.
