Carbide Nozzle Scenario Porogaramu Ubwoko bwo Kurwanya no Guha Agaciro

Carbide nozzles nibintu byuzuye bikozwe no gucumura ibikoresho bikomeye bya karbide (cyane cyane tungsten carbide, WC) hamwe nibyuma (nka cobalt, Co). Kurata ubukana bwa Vickers burenga 1300 HV, kwihanganira kwambara neza (inshuro 10-20 kurenza ibyuma byihuta cyane), hamwe nubushyuhe bukomeye bwumuriro, byahindutse ibice byingenzi bidasubirwaho mubice nko gutunganya inganda, ingufu, na electronics. Urufunguzo rwo kugwiza agaciro rwibikorwa byabo ruri muburyo butandukanye bwo guhuza n'imihindagurikire y'ikirere - guhuza ubwoko bwa nozzle iburyo n'imikorere yihariye yo guhuza imikorere, kuramba, no gukoresha neza.

Mu buryo bwo gutunganya indege zangiza, harimo gukuramo umucanga kugirango ukureho ingese hejuru y’amazi hamwe n’umuvuduko ukabije w’amazi ukata ibyapa, urukuta rwimbere rwa nozzle rukomeje kwibasirwa no gukurwaho n’umuvuduko mwinshi (kugeza kuri 800 m / s) uduce duto duto (urugero: alumina, karubide ya silicon). Kubwibyo, ingano nziza ya karbide nozzles (hamwe na tungsten karbide ingano ya 0.5-1μm) nibyo byiza. Microstructure ya ultra-dense igabanya cyane kwinjiza ibice byangiza, bikagabanya umuvuduko wimbere wurukuta rwimbere - byongerera igihe cyumurimo inshuro 3-5 ugereranije nubutaka gakondo bwa ceramic no kugabanya igihe cyo gusimbuza kenshi.

Kubijyanye nubushyuhe bwo hejuru cyane nkinganda zogosha ibyuma hamwe no gutunganya imyanda, nozzles igomba kwihanganira igihe kirekire guhura nubushyuhe bwo hejuru 800-1000 while mugihe ikirere gikomeza guhagarara neza. Hano, tungsten-cobalt karbide nozzles (hamwe na cobalt ihuza ibice 6% -8%) ikora neza bidasanzwe. Igikoresho cya cobalt kigira umurunga uhamye hamwe na tungsten ya karbide ya karubide, bikarinda kumeneka kwatewe no guterwa nubushyuhe bwumuriro no kwemeza ingaruka ziterwa na spray atomisation, ibyo bikaba ari ingenzi cyane kugirango imyuka ihumanya neza kandi ikureho ivumbi.

Muburyo bwogutanga amazi neza nka semiconductor chip yogusukura hamwe na LCD ikingira, nubwo imivurungano ntoya ishobora kuganisha kuri micro-inenge (urugero, 0.1μm-ibipimo byerekana) hejuru yibicuruzwa. Carbide nozzles isukuye - hamwe nurukuta rwimbere rwimbere rwa Ra≤0.02μm (bigerwaho binyuze mu gusya ibyiciro 12)

Kubidukikije bicukurwamo amabuye aremereye (urugero, gucukura amabuye yamakara munsi yubutaka no gutwara imiyoboro itunganya amabuye y'agaciro), nozzles ihura nibibazo bibiri: kugongana kumashanyarazi biva mubice byamakara / urutare no kwangirika kumazi akungahaye kumabuye y'agaciro. Carbide izengurutswe cyane (ifite uburebure bwurukuta rwa 5-8mm, inshuro 2-3 zubunini busanzwe) hamwe nuburinganire bwo kurwanya ruswa (urugero, isahani ya chromium) bikemura iki kibazo. Bagabanya inshuro zisimburwa hejuru ya 60% ugereranije nozzle zisanzwe, bikagabanya amafaranga yo gufata neza imishinga icukura amabuye y'agaciro.

Agaciro ko kumenya karbide nozzles ikomoka kuri ubu buryo bwimbitse-ubwoko bwimikoranire. Muguhuza ibikoresho bifatika (urugero, guhindura ibirimo cobalt), ibishushanyo mbonera (urugero, inkuta zibyimbye), hamwe no gutunganya neza (urugero, polishinge ultra-fine polishinge) kubikenerwa ninganda zihariye, ntibagabanya gusa amafaranga yo kubungabunga 30% -50% kandi banatezimbere umusaruro muke kuri 20% -30% ariko banashyigikira iterambere ryikoranabuhanga mubice byo murwego rwo hejuru-bisabwa na metero 5. Nkuko inganda nkingufu nshya, semiconductor, hamwe nindege zikurikirana ibipimo ngenderwaho bihanitse, uburyo bwo kwerekana imiterere ya karbide nozzles bizarushaho gufungura ubushobozi bwabyo, bibe moteri yingenzi yo kuzamura inganda niterambere ryiza.
