Muminda yemaindasitiri yakaita seyemigodhi, simbi, kuchengetedzwa kwemakemikari nezvakatipoteredza, mapombi eslurry anogara achitakura zvinhu zvinoparadza zvine zvidimbu zvakasimba zvakaita se "moyo wemaindasitiri". Sechikamu chikuru chechikamu chinopfungaira, kusarudzwa kwezvinhu kunosarudza zvakananga hupenyu hwebasa uye kushanda zvakanaka kwemuviri wepombi. Kushandiswa kwezvinhu zve silicon carbide ceramic kuri kuunza budiriro huru mumunda uyu.
1, musimboti wekushanda: Hunyanzvi hwekutumira hunobatanidza kuomarara uye kuchinjika
Pombi yesimbi yesilicon carbide ceramic slurry inogadzira simba re centrifugal kuburikidza nekutenderera nekukurumidza kwe impeller, iyo inosveta mvura yezvikamu zvakasanganiswa zvakasimba kubva pakati, inoidzvinyirira pamwe chete nepaipi inoyerera, uye inoiburitsa nenzira yakananga. Chinhu chikuru chayo chiri mukushandiswa kwesimbi yakagadzirwa nesilicon carbide ceramic, guard plate nezvimwe zvinhu zvinopisa zvakanyanya, izvo zvinogona kuchengetedza kuomarara kwechimiro uye kudzivirira kukuvadzwa kwemidziyo yakaoma panguva yekushanda nekukurumidza.
2、 Kubatsira kwe "kudzivirira kwakapetwa kane" kwesimbi dzesilicon carbide
1. "Nhumbi" dzakasimba kwazvo: Kuomarara kweMohs kunosvika padanho repfumbamwe (kwechipiri kubva padhaimani), kuchidzivirira kuchekwa kwezvidimbu zvekuomarara zvakanyanya zvakaita sejecha requartz, uye hupenyu hwekushanda hwakareba kakawanda kupfuura zvinhu zvesimbi zvechinyakare.
2. "Chidziviriro" chemakemikari: Chimiro chekristaro chakasimba chinoumba chipingamupinyi chechisikigo chinodzivirira ngura, chinogona kutsungirira ngura dzakadai semaacid akasimba uye munyu.
3. "Kurema" kushoma: Kuwanda kwesimbi kunongova chikamu chimwe muzvitatu chesimbi, zvichideredza kusagadzikana kwemidziyo uye zvinobudirira kuderedza kushandiswa kwesimba.
4. Kugadzikana kwekupisa "core": inochengetedza kushanda kwakasimba pa1350 ℃ kudzivirira kutadza kwekuvhara kunokonzerwa nekuwedzera kwekupisa uye kudzikira.
3, Sarudzo yakangwara yekushanda kwenguva refu
Zvakanakira zvesilicon carbide ceramics zvinoshandura kugona kwemidziyo kuenderera mberi: kugadzirisa nguva shoma yekushanda, kudzoserwa kwezvikamu zvishoma, uye chiyero chakakwirira chekushandisa simba zvakanaka. Kuvandudzwa uku kwakachinja pombi yeslurry kubva pa "mudziyo unodyiwa" kuenda ku "pfuma yenguva refu", yakakodzera mamiriro ekushanda akaomarara emaawa makumi maviri nemana.
Semugadziri wenyanzvi wezvinhu zve silicon carbide ceramic,Shandong ZhongpengIva nechokwadi chekuti chikamu chimwe nechimwe checeramic chine hunhu hwakanaka hwemakanika uye hunhu hwakakwana hwepamusoro kuburikidza nehunyanzvi hwakasiyana-siyana hwepatent uye maitiro ekunyorovesa akarurama. Kusarudza pombi yeslurry yesilicon carbide ceramic zvinoreva kuisa simba rinogara kwenguva refu mukugadzirwa kwemaindasitiri kuburikidza nehunyanzvi hwezvinhu.
