Izinhlobo Zamadayimane

Uhlobo lwedayimane olusetshenziswa ekugayeni nasekupholisheni uketshezi luthinta kakhulu ukusebenza komkhiqizo wokugcina. Amadayimane asezimbonini ahlukaniswa ngezigaba zemvelo kanye nezokwenziwa, ngalinye likhiqizwa ngezindlela ezahlukene.

I-micro-powder yedayimane yemvelo ivame ukwenziwa ngamadayimane asezingeni eliphansi, okuthi, nakuba engafanele ikhwalithi yamatshe ayigugu, avame ukusetshenziswa ezisetshenziswa ezimbonini. Kodwa-ke, amadayimane emvelo ayivelakancane futhi angashintshashintshi ezinsizeni zemvelo.

Amadayimane okwenziwaNgakolunye uhlangothi, kukhiqizwa ngezinqubo zokushisa okuphezulu/ukucindezela okuphezulu. Le ndlela ihilela ukusebenzisa i-catalyst yensimbi ukuguqula i-graphite ibe yidayimane, evame ukubizwa ngokuthi ama-abrasives edayimane elilodwa. Ikhwalithi yalawa madayimane okwenziwa ingahluka kakhulu, kusukela ekuhlanzekeni okuphezulu kuya emazingeni aphezulu okungcola. I-micro-powder yedayimane elilodwa idalwa ngokuchoboza izinhlayiya zedayimane bese i-micronizing i-powder, okuholela entweni esetshenziswa kabanzi.

Olunye uhlobo lwedayimane elenziwe lukhiqizwa ngokuqhuma kweziqhumane ezisongwe ezindongeni ze-graphite. Ukushisa okukhulu kanye nokucindezela okuvela ekuqhumeni kuguqula i-graphite ibe yi- idayimane elicwebezelayo, ngokuvamile okuholela osayizi bedayimane abangaphansi kwama-micron ayi-10, okudinga futhi i-micronization ukuze isetshenziswe ekugayeni nasekupholisheni. Nakuba amadayimane e-polycrystalline engasetshenziswa kabanzi njengedayimane enekristalu elilodwa, avame ukubiza kakhulu.

Ngaphezu kwalokho, amadayimane amancane adalwa ezindaweni ezilawulwayo ngokuqhuma iziqhumane zepulasitiki. Ukuqhuma kukhiqiza insalela equkethe inani elincane lamadayimane asezingeni eliphansi, aziwa ngokuthi amadayimane amancane. Ngemva kokuhlanza nokuhlakaza, lawa madayimane amancane avame ukuba ngaphansi kwe-micron eyi-1. Nakuba ukukhiqizwa kwawo kungeyona inkimbinkimbi njengokwamadayimane e-single-crystal noma e-polycrystalline, awafani nokusebenza kwamadayimane amancane asayizi we-micron ekugayweni nasekupholishweni.

Phakathi kwazo zonke izici ezithonya ukusebenza kokugaya nokupholisha koketshezi, usayizi wezinhlayiya ubalulekile. Usayizi wezinhlayiya ojwayelekile unquma izinga lokususwa kwezinto kanye namazinga okuklwebheka noma ukuklwebheka okubangelwa ubuso. Kokubili amadayimane ekristalu elilodwa kanye ne-polycrystalline angalinganiswa ngokusekelwe kubukhulu obuqondile obujwayelekile kanye nokubekezelelana kwamaphesenti.

Uma ufuna imikhiqizo yedayimane esezingeni eliphezulu, xhumana neBoreas ukuze uthuthukise ukusebenza kahle kwemishini yakho kanye nekhwalithi yomkhiqizo!
