Ama-Tungsten Carbide Blades
Ngokukhethwa kwebanga eliphezulu, ama-submicron okusanhlamvu ama-tungsten carbide blades angalolwa abe onqenqemeni lwensingo ngaphandle kokonakala okungokwemvelo okuvame ukuhlotshaniswa ne-carbide evamile. Nakuba ingamelani nokushaqeka njengensimbi, i-carbide imelana ngokwedlulele, nobulukhuni obulingana no-Rc 75-80. Impilo ye-blade okungenani engu-50X yensimbi evamile ingalindelwa uma ukuchopha nokuphuka kugwenywa.
Njengoba nje endabeni yokukhethwa kwensimbi, ukukhetha izinga elifanelekile le-tungsten carbide (WC) kuyinqubo eyinkimbinkimbi ehlanganisa ukukhetha okusengozini phakathi kokumelana nokugqoka kanye nokuqina/ukumelana nokushaqeka. I-tungsten carbide efakwe usimende yenziwa ngokufakwa (emazingeni okushisa aphezulu) inhlanganisela ye-tungsten carbide powder ne-cobalt eyimpushana (Co), insimbi eyi-ductile esebenza "njenge-binder" yezinhlayiya ze-tungsten carbide eziqine kakhulu. Ukushisa kwenqubo ye-sintering akubandakanyi ukusabela kwezingxenye ezingu-2, kodwa kunalokho kubangela ukuthi i-cobalt ifinyelele esimweni soketshezi oluseduze futhi ibe njenge-encapsulating glue matrix yezinhlayiya ze-WC (ezingathintwa ukushisa). Amapharamitha amabili, okuyisilinganiso se-Cobalt kuya ku-WC kanye nosayizi wezinhlayiyana ze-WC, alawula ngokuphawulekayo izakhiwo zempahla eyinqwaba yocezu oluwumphumela "we-tungsten carbide".
Ukucacisa usayizi omkhulu wezinhlayiyana ze-WC kanye nephesenti eliphezulu le-Cobalt kuzoveza ingxenye ekwazi ukumelana nokushaqeka (namandla amakhulu omthelela). Uma usayizi wokusanhlamvu we-WC ucinene (ngakho-ke, indawo engaphezulu ye-WC okufanele igcotshwe nge-Cobalt) futhi uma i-Cobalt isetshenziswa kancane, ingxenye ewumphumela izoqina futhi imelane kakhulu. Ukuze uthole ukusebenza okuhle kakhulu ku-carbide njengento ye-blade, kubalulekile ukugwema ukwehluleka konqenqema ngaphambi kwesikhathi okubangelwa ukuchotshozwa noma ukuphuka, kuyilapho ngesikhathi esifanayo uqinisekisa ukumelana nokugqokwa okuphezulu.
Njengodaba olungokoqobo, ukukhiqizwa kwemiphetho yokusika ebukhali kakhulu, ene-engeli eqinile ibeka ukuthi kusetshenziswe i-carbide ecolekile ekufakweni kwe-blade (ukuze kuvinjwe ama-nick amakhulu nemiphetho emangelengele). Uma kubhekwa ukusetshenziswa kwe-carbide enosayizi ojwayelekile wokusanhlamvu we-micron engu-1 noma ngaphansi, ukusebenza kwe-carbide blade; ngakho-ke, ithonywa kakhulu yi-% ye-Cobalt kanye nejometri enqenqemeni ecacisiwe. Ukusika izinhlelo zokusebenza ezibandakanya ukushaqeka okumaphakathi kuya phezulu kusingathwa kangcono kakhulu ngokucacisa amaphesenti angu-12-15 e-Cobalt kanye nejiyomethri enqenqemeni ene-engeli enqenqemeni engaba ngu-40º. Izinhlelo zokusebenza ezibandakanya imithwalo elula futhi zibeka iprimiyamu ekuphileni kwe-blade ende zingamakhandidethi alungile e-carbide equkethe amaphesenti angu-6-9 e-cobalt futhi ene-engeli enqenqemeni ebangeni elingu-30-35º.
I-HUAXIN CARBIDE ime ngomumo ukukusiza ekuzuzeni ibhalansi ephezulu yezakhiwo ezokuvumela ukuthi uthole ukusebenza okuphezulu kumablade akho e-carbide.
I-HUAXIN CARBIDE inikezela ngokukhethwa kwama-razor slitting blades anesitoko
