Pombi inodzivirira kupfeka yakagadzirwa nesilicon carbide ceramic
Mapaipi asingapararike nesilicon carbide mapaipi akagadzirwa zvakanyanya nesilicon carbide uye anoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana. Kukwikwidzana kwawo kukuru ndekwekuti:
(1) Chimurenga cheHupenyu
Pakutakura zvinhu zvinokuvadza zvakaita sedota remarasha nedota remarasha, hupenyu hwesimbi hunopfuura kagumi pane hwesimbi, zvichideredza kurasikirwa nekutsiva nguva nenguva.
（2）Mamiriro ekushanda akanyanya anowanikwa pasi rose
Kushanda kwakagadzikana kubva -50 ℃ kusvika 1600 ℃, ine simba rekudzivirira kupisa kuti isatsemuke, yakakodzera mamiriro ekupisa kwakanyanya akadai seindasitiri yesimbi nemakemikari.
(3) Mashandisirwo akawanda echinhu chimwe chete
Gadzirisai panguva imwe chete matambudziko mana makuru ekusakara, ngura, kupisa kwakanyanya, uye kudzivirira kuputika.
（4）Inorema uye inochengetedza simba
Dhizaini yakareruka inoderedza mari yekufambisa nekuisa, uye kukweshana kwakaderera kunoderedza kushandiswa kwesimba rekupomba.
Kubatsira kukuru kwemapaipi esilicon carbide zvichienzaniswa nezvinhu zvechinyakare:
| Chiyero chekushanda | Mapaipi eSilicon carbide | Mapaipi esimbi/epurasitiki |
| Kuramba kupfeka | Kuomarara kwesimbi 2800HV (kupetwa kashanu kupfuura simbi), hupenyu hwepombi hurefu kagumi kupfuura hwemapaipi asiri esimbi | Simbi inowanzo pwanyika, nepo purasitiki isina kuomarara kwakanyanya (PE<1 HV) |
| Tembiricha yakakwira kuramba | Inodzivirira kupisa kwakanyanya kwe1600 ℃ uye kupisa kwakanyanya (coefficient yekuwedzera kwekupisa kwe4 × 10 ⁻⁶/℃) | Simbi isina ngura inogona kuoxidation kana tembiricha yakakwira, nepo mapurasitiki achiramba tembiricha iri pasi pe80 ℃ |
| Kuramba ngura | Haipindi maasidhi akasimba (concentrated sulfuric acid), mabhesi akasimba, uye ngura yesimbi yakanyungudutswa | Simbi isina ngura inosangana nengura kana yakasangana ne chloride ions, nepo purasitiki isina makemikari akawanda anodzivirira. |
| Huremu hwakareruka | Huremu hwe3.0~3.14 g/cm³ (60% yakareruka kupfuura simbi) | Mapaipi esimbi akakura uye anodhura zvakanyanya pakuaisa |
| Kuwedzera Kwebasa | Kuchena kwemhando ye semiconductor hakuchinji (kusasimba kwemhepo) | Simbi dzinoda kurapwa kwakawedzerwa kudzivirira kuputika, nepo mapurasitiki achiwanzosvibiswa |
Muchidimbu, hapana imwe nzira yekubvisa mapombi esilicon carbide kana uchitakura zvinhu zvinoparadza zvakanyanya uye zvisingapfeki zvakaita seasidi slurry uye ash yegesi inopisa zvakanyanya.
Kana muine mibvunzo, ndapota inzwa wakasununguka kutibata chero nguva.
Shandong Zhongpeng Special Ceramics Co., Ltd ndeimwe yemhando huru dzesilicon carbide ceramic itsva muChina. SiC technical ceramic: Kuomarara kwaMoh kwa9 (Kuomarara kwaNew Moh kwa13), nekusimba kwakanaka pakukukurwa nekuora, kusimba kwakanaka - kusimba uye kudzivirira oxidation. Hupenyu hwebasa rechigadzirwa cheSiC hwakareba ka4 kusvika ka5 kupfuura 92% alumina material. MOR yeRBSiC yakapetwa ka5 kusvika ka7 kupfuura SNBSC, inogona kushandiswa kune mamwe maumbirwo akaomarara. Maitiro ekukosha kwemashoko anokurumidza, kuendesa kwacho kwakaitwa sezvakavimbiswa uye mhando yacho haina kukosha. Tinogara tichiramba tichipikisa zvinangwa zvedu uye tinopa moyo yedu kunharaunda.
