Silicon carbide inodzivirira chubhu
Mumaindasitiri umo mamiriro akanyanya anotyisidzira kuvimbika kwemidziyo,silicon carbide (SiC) inodzivirira machubhukubuda sechigadziro chepasi. Kusiyana nemidziyo yekudzivirira yakajairika, SiC machubhu anosanganisa advanced material sainzi nehuinjiniya hwakasimba kuchengetedza zvakakosha zviridzwa uye maitiro.Ine zvinotevera zvakanakira:
1. Dziviriro Isingaenzaniswi muMamiriro Akashata
SiC inodzivirira machubhu inoita seyekutanga mutsara wekudzivirira munzvimbo umo kukundikana isiri sarudzo:
(1) Thermal Defense: Ramba tembiricha yakadzikama kusvika 1600 ° C, kudzivirira masensa, thermocouples, kana probes kubva kusimbi yakanyungudutswa, marimi, uye plasma.
(2) Chemical Immunity: Ramba kuonda kubva kumaasidhi (eg sulfuric, hydrochloric), alkalis, uye magasi anoshanda senge chlorine kana sulfur oxides.
Abrasion Resistance: Dzivirira kubva kuzvinhu zvinokukurisa mumibhedha yakanyungudika, marasha gasifiri, kana mashandiro emigodhi.
2. Kururamisa uye Kugadzikana Kwezviyero Zvinokosha
Mumaindasitiri epamusoro-soro maitiro, kurongeka kwakakosha. SiC machubhu anowedzera kuvimbika ne:
(1) Kuderedza Kupindira Kwechiratidzo: Zvisiri-zvinoita zvivakwa zvinodzivirira kukanganiswa kwemagetsi muma sensors emagetsi.
(2) Thermal Kugadzikana: Pedyo-zero thermal deformation inovimbisa kuenderana kunoenderana uye kuyerwa kwechiyero pasi pekukurumidza kushanduka kwekushisa.
(3) Gasi-Yakasimba Kutendeseka: Impermeable chimiro chinodzivirira gasi kupinda, yakakosha kune vacuum masisitimu kana inodzorwa mamiriro ekunze.
3. Kugonesa Next-Generation Technologies SiC ekudzivirira machubhu anovhura mitsva mundima dzichiri kusimukira:
(1) Hydrogen Economy: Shandira semasheti akasimba emagetsi emagetsi mukugadzirwa kwehydrogen, kuchengetedza, uye masero emafuta, kuramba embrittlement uye yakanyanya-kumanikidzwa H₂ kuratidzwa.
(2) Semiconductor Kugadzira: Chengetedza zvinopenya uye zvinopisa zvinonzwa muCVD (Chemical Vapor Deposition) zvinobatika kubva kune zvinoparadza precursors senge silane kana ammonia.
(3)Space Kuongorora: Shield chiridzwa mumaroketi enjini uye mapuraneti probes kubva kune yakanyanyisa kupisa gradients uye cosmic mwaranzi.
4. Mutengo-Kubudirira kuburikidza nehupenyu hurefu
Nepo maSiC machubhu aine mitengo yepamusoro yepamusoro, hupenyu hwavo hunobatsira tsanangurazve kukosha:
(1) Yakaderedzwa Downtime: Outlast simbi kana quartz dzimwe nzira ne 4-6x mune abrasive kana acidic marongero, kuderedza kusarongeka kwekugadzirisa.
(2) Zero Coating Zvinodiwa: Kusiyana nesimbi inoda machira ekudzivirira, SiC's inherent properties inobvisa inodzokororwa mari yekurapa pamusoro.
(3) Reusability: Pukunyuka maitiro akawanda ekutenderera mumashandisirwo akaita sesimbi yekukanda kana girazi kugadzira pasina kushatisa.
5. Kugadzirisa kune Specialized Needs
SiC inodzivirira machubhu anochinjika kune niche matambudziko kuburikidza neakagadzirirwa engineering:
(1) Hybrid Dhizaini: Batanidza nesimbi kana ceramics kune akawanda-anoshanda maassemblies (semuenzaniso ma threaded connectors, flanges).
(2) Kugadziridzwa kwePamusoro: Imba yakakwenenzverwa yekushandiswa kwemaziso kana mameseji ekunze kuti awedzere kupisa.
(3) Size Flexibility: Yakagadzirwa kubva pamamirimita (lab-scale reactors) kusvika kumamita (maindasitiri emoto).
6. Sustainability Alignment
SiC machubhu anotsigira eco-hushamwari maindasitiri maitiro:
(1) Kuchengetedza Simba: Kunyanya kupisa kwemafuta kunoderedza kushandiswa kwemafuta echoto kusvika ku20% zvichienzaniswa nenhoo dzesimbi.
(2) Kuderedza Marara: Hupenyu hwesevhisi hurefu hunocheka tsvina yezvinhu kubva pakudzokororwa kazhinji.
(3) Kuderedza Muchetura: Bvisa kudiwa kwemajasi ane ngozi (semuenzaniso, nickel-based alloys) munzvimbo dzinoparadza.
Shandong Zhongpeng Special Ceramics Co., Ltd ndeimwe yeyakakura silicon carbide ceramic zvinhu zvitsva mhinduro muChina. SiC technical ceramic: Kuomarara kweMoh ndeye 9 (Kuoma kweMoh kutsva ndeye 13), nekupokana kwakanyanya kukukurwa nekuora, kunyura kwakanakisa - kuramba uye anti-oxidation. Hupenyu hwesevhisi yechigadzirwa cheSiC hwakareba 4 kusvika kashanu kupfuura 92% alumina zvinhu. Iyo MOR yeRBSiC ndeye 5 kusvika 7 nguva iyo yeSNBSC, inogona kushandiswa kune mamwe maumbirwo akaoma. Iyo quotation process inokurumidza, kuendesa kwakavimbiswa uye mhando ndeyechipiri kune imwe. Isu tinogara tichishingirira kupikisa zvinangwa zvedu uye nekudzorera moyo yedu kunharaunda.
