Ama-Tungsten Carbide Blades
Ngokukhethwa okuhle kakhulu kwebanga, ama-blade e-tungsten carbide anosayizi we-submicron angacijwa abe yi-razor edge ngaphandle kobuthakathaka obungokwemvelo obuvame ukuhlotshaniswa ne-carbide evamile. Nakuba ingenawo amandla okushaqeka njengensimbi, i-carbide imelana nokuguguleka kakhulu, inobunzima obulingana ne-Rc 75-80. Isikhathi se-blade okungenani ama-blade ensimbi avamile angu-50X singalindelwa uma kugwenywa ukuqhekeka nokuphuka.
Njengoba kunjalo ngokukhethwa kwensimbi, ukukhetha izinga eliphezulu le-tungsten carbide (WC) kuyinqubo eyinkimbinkimbi ehilela ukukhetha okulimele phakathi kokumelana nokuguguleka kanye nokuqina/ukumelana nokushaqeka. I-tungsten carbide eyenziwe ngosimende yenziwa ngokusinta (ekushiseni okuphezulu) inhlanganisela ye-tungsten carbide powder ne-cobalt ephuphusiwe (Co), insimbi ethambile esebenza njenge-"binder" yezinhlayiya ze-tungsten carbide eziqinile kakhulu. Ukushisa kwenqubo yokusinta akubandakanyi ukusabela kwezingxenye ezimbili, kodwa kunalokho kubangela i-cobalt ukuthi ifinyelele esimweni esicishe sibe uketshezi futhi ibe njenge-glue matrix ehlanganisa izinhlayiya ze-WC (ezingathinteki ukushisa). Amapharamitha amabili, okungukuthi isilinganiso se-Cobalt kuya ku-WC kanye nosayizi wezinhlayiya ze-WC, alawula kakhulu izakhiwo zezinto eziningi zengxenye "ye-tungsten carbide eyenziwe ngosimende" ephumayo.
Ukucacisa usayizi wezinhlayiya ze-WC ezinkulu kanye nephesenti eliphezulu le-Cobalt kuzoveza ingxenye engamelani nokushaqeka kakhulu (kanye namandla aphezulu okushaya). Uma usayizi wezinhlamvu ze-WC unciphile (ngakho-ke, indawo engaphezulu ye-WC okumele imbozwe nge-Cobalt ingaphezulu) futhi i-Cobalt ingasetshenziswa kancane, ingxenye ephumayo izoba nzima futhi imelane nokuguguleka. Ukuze uthole ukusebenza okuhle kakhulu kwe-carbide njengento ye-blade, kubalulekile ukugwema ukwehluleka konqenqema ngaphambi kwesikhathi okubangelwa ukuqhekeka noma ukuphuka, ngenkathi ngesikhathi esifanayo kuqinisekiswa ukumelana okuhle kokuguguleka.
Njengendaba engokoqobo, ukukhiqizwa kwemiphetho yokusika ebukhali kakhulu, ene-engile ebukhali kusho ukuthi kusetshenziswe i-carbide encane eqoshwe kahle ekusetshenzisweni kwe-blade (ukuze kuvinjelwe ama-nick amakhulu kanye nemiphetho eqondile). Uma kubhekwa ukusetshenziswa kwe-carbide enobukhulu obuphakathi kwe-grain obuyi-1 micron noma ngaphansi, ukusebenza kwe-carbide blade; ngakho-ke, kuthonywa kakhulu yi-% ye-Cobalt kanye ne-edge geometry ecacisiwe. Izinhlelo zokusika ezibandakanya imithwalo yokushaqeka ephakathi nendawo kuya phezulu ziphathwa kangcono ngokuchaza i-Cobalt engu-12-15% kanye ne-edge geometry ene-edge angle efakiwe engaba ngu-40º. Izinhlelo zokusebenza ezibandakanya imithwalo elula futhi ezibeka i-premium empilweni ye-blade ende ziyizikhethelo ezinhle ze-carbide equkethe i-cobalt engu-6-9% futhi ene-edge angle efakiwe ebangeni elingu-30-35º.
I-HUAXIN CARBIDE ikulungele ukukusiza ekufinyeleleni ibhalansi efanele yezakhiwo ezizokuvumela ukuthi uthole ukusebenza okuphezulu kakhulu kusuka kuma-blade akho e-carbide.
I-HUAXIN CARBIDE inikeza ukukhethwa kwama-carbide razor slitting blades agcwele
