Carbide Nozzle Scenario Application Type Adaptation ndi Kuzindikira Mtengo

Carbide nozzles ndi zigawo zolondola zopangidwa ndi sintering hard carbide materials (makamaka tungsten carbide, WC) ndi zomangira zitsulo (monga cobalt, Co). Podzitamandira kuuma kwa Vickers kopitilira 1300 HV, kukana kuvala kwabwino kwambiri (nthawi 10-20 kuposa chitsulo chothamanga kwambiri), komanso kukhazikika kwamphamvu kwamafuta, asanduka magawo osasinthika m'magawo monga kukonza mafakitale, mphamvu, ndi zamagetsi. Chinsinsi chokulitsa mtengo wawo wakugwiritsa ntchito chagona pakusintha kwamtundu wanthawi yeniyeni - kufananiza mtundu wa mphuno yoyenera ndi momwe amagwirira ntchito kuti azitha kugwira bwino ntchito, kulimba, komanso kuwononga ndalama.

M'zochitika za abrasive jet processing, kuphatikizapo sandblasting yochotsa dzimbiri pamwamba ndi kudula kwa jeti kwazitsulo zachitsulo, khoma lamkati lamkati limakhudzidwa mosalekeza ndikugwedezeka ndi kuthamanga kwambiri (mpaka 800 m / s) particles abrasive (mwachitsanzo, alumina, silicon carbide). Pachifukwa ichi, ma nozzles a carbide abwino (okhala ndi tungsten carbide size ya 0.5-1μm) ndiye chisankho choyenera. Kapangidwe kawo kakang'ono kakang'ono kamene kamapangitsa kuti tinthu ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono, kuchepetsa kuchuluka kwa mavalidwe a khoma lamkati-kukulitsa moyo wautumiki ndi maulendo 3-5 poyerekeza ndi milomo ya ceramic yachikhalidwe ndikuchepetsa nthawi yochepetsera nthawi zambiri.

Pazinthu zotentha kwambiri zamafakitale monga kuyeretsa chitsulo chosungunula gasi ndikuchotsa zinyalala, ma nozzles ayenera kupirira kutentha kwanthawi yayitali kwa 800-1000 ℃ ndikusunga kukhazikika kwa mpweya. Apa, tungsten-cobalt carbide nozzles (ndi cobalt binder zili 6% -8%) amachita bwino kwambiri. Cobalt binder imapanga chomangira chokhazikika ndi njere za tungsten carbide, kuteteza kusweka kwamapangidwe komwe kumachitika chifukwa cha kugwedezeka kwamafuta ndikuwonetsetsa kuti kutsitsi kwa atomization kumagwira ntchito, komwe kuli kofunikira pakuchotsa mpweya wabwino wa flue ndikuchotsa fumbi.

M'magawo operekera madzi mwatsatanetsatane monga kuyeretsa chip cha semiconductor ndi zokutira pagulu la LCD, ngakhale chipwirikiti chochepa chamadzimadzi chimatha kubweretsa zovuta zazing'ono (mwachitsanzo, zikwapa za 0.1μm) pamalo azinthu. Mphuno za carbide zopukutidwa - zokhala ndi khoma lamkati la Ra≤0.02μm (lomwe limakwaniritsidwa kudzera mu magawo 12) - amachotsa madontho amadzimadzi, kupangitsa kufalikira kwautsiridwe kofananira (ndi kupatuka kwa zosakwana 5%) ndikukwaniritsa zofunikira zenizeni zamakampani opangira zida zamagetsi.

Pamalo ochitira migodi movutikira (monga, kupondereza fumbi la pansi pa mgodi wa malasha ndi mayendedwe a mapaipi okonza mamineral), mitsinje imayang'anizana ndi zovuta ziwiri: kugunda kwamakina kuchokera ku zidutswa za malasha/miyala ndi dzimbiri kuchokera kumadzi okhala ndi mchere wambiri. Mipukutu ya carbide yokhuthala (yokhala ndi makulidwe a 5-8mm, 2-3 nthawi ya nozzles wamba) ndi zokutira zotsutsana ndi dzimbiri (mwachitsanzo, plating chromium) zimathetsa vutoli. Amachepetsa ma frequency osinthira ndi 60% poyerekeza ndi ma nozzles wamba achitsulo, kutsitsa mtengo wokonza mabizinesi amigodi.

Kuzindikira kufunika kwa milomo ya carbide kumachokera ku mgwirizano wozama wamtunduwu. Mwa kukonza zinthu zopangira zinthu (mwachitsanzo, kusintha kobalt), mapangidwe apangidwe (mwachitsanzo, makulidwe akukhuthala), komanso kukonza mwatsatanetsatane (mwachitsanzo, kupukuta kopitilira muyeso) kuti agwirizane ndi zofunikira zamakampani, samangodula ndalama zolipirira ndi 30% -50% ndikuwongolera magwiridwe antchito ndi 20% -30% komanso amathandizira luso laukadaulo laukadaulo. chigawo chodula (chofuna ma nozzles ndi kulondola kwazithunzi za ± 0.005mm). Monga mafakitale monga mphamvu zatsopano, ma semiconductors, ndi zakuthambo zimatsata miyezo yapamwamba yogwirira ntchito, kusinthika kokhazikika kwa ma carbide nozzles kudzatsegulanso kuthekera kwawo, kukhala choyendetsa chachikulu pakukweza mafakitale ndi chitukuko chapamwamba.
