Silicon carbide inodzivirira chubhu

Mumaindasitiri umo mamiriro ezvinhu akaipisisa anotyisidzira kuvimbika kwemidziyo,machubhu ekudzivirira esilicon carbide (SiC)Inobuda semhinduro itsva. Kusiyana nezvinhu zvekudzivirira zvechinyakare, machubhu eSiC anosanganisa sainzi yezvinhu zvepamusoro neinjiniya yakasimba kuchengetedza zvishandiso zvakakosha uye maitiro. Ane zvakanakira zvinotevera:

1. Dziviriro Isina Kuenzana Mumamiriro Ehukasha

Machubhu ekudzivirira eSiC anoshanda senzira yekutanga yekudzivirira munzvimbo dzisina mukana wekukundikana:

（1）Dziviriro yeThermal: Inodzivirira tembiricha inosvika 1600°C, masensa ekudzivirira, mathermocouple, kana maprobes kubva kusimbi dzakanyungudutswa, marimi emoto, uye plasma.

（2）Kudzivirirwa Kwemakemikari: Kudzivirira ngura kubva kumaacids (semuenzaniso sulfuric, hydrochloric), alkalis, uye magasi anochinja-chinja akadai sechlorine kana sulfur oxides.

Kuramba Kukwesha: Dzivirirai kubva kuzvinhu zvinokukurwa mumibhedha ine mvura, muzvishandiso zvemagetsi zvemarasha, kana mumabasa ekuchera.

2. Kunyatsojeka uye Kugadzikana Kwezviyero Zvakakosha

Mumabasa emaindasitiri ane njodzi huru, kururama kunonyanya kukosha. Machubhu eSiC anowedzera kuvimbika ne:

（1）Kuderedza Kukanganiswa kweMasaini: Hunhu husingafambise magetsi hunodzivirira kukanganisika kwema electromagnetic muma sensor emagetsi.

（2）Kugadzikana kweThermal: Kushanduka kwethermal kuri pedyo nezero kunoita kuti kurongeka kuenderane uye kuyera kwakarurama kana tembiricha ikachinja-chinja nekukurumidza.

（3）Kusimba Kwakasimba Kwegasi: Chimiro chisingapindi mvura chinodzivirira kupinda kwegasi, chakakosha kune masisitimu evacuum kana mhepo inodzorwa.

3. Kugonesa Tekinoroji yeChizvarwa Chinotevera (Next-Generation Technologies) machubhu ekudzivirira eSiC anovhura hunyanzvi muminda iri kubuda:

（1）Kuchengetedza Hydrogen: Inoshanda semidziyo yakasimba yekuona ma sensors mukugadzirwa kwehydrogen, kuchengetwa, uye ma fuel cells, ichidzivirira kupwanyika uye kusvibiswa ne high-pressure H₂.

（2）Kugadzira Semiconductor: Kudzivirira masensa ekuona uye ekupisa muCVD (Chemical Vapor Deposition) reactors kubva kuzvinhu zvinoparadza zvakaita se silane kana ammonia.

（3）Kuongorora Muchadenga: Kudzivirira maroketi muinjini nemapuraneti kubva mukupisa kwakanyanya uye mwaranzi yemuchadenga.

4. Kushanda Nesimba Mukurarama Kwenguva Yakareba

Kunyange zvazvo machubhu eSiC aine mitengo yakakwira yekutanga, mabhenefiti awo ehupenyu anotsanangura kukosha kwawo patsva:

（1）Nguva Yekudzikira Kwekushanda: Nzira dzesimbi kana dzequartz dzinoshandiswa kunze kwesimbi ne4–6x munzvimbo dzinopisa kana dzine acidic, zvichideredza kugadziriswa kusina kurongwa.

（2）Zvinodiwa paKuputira Zvisina Kukwana: Kusiyana nesimbi dzinoda machira ekudzivirira, hunhu hweSiC hunobvisa mari yekurapa pamusoro inodzokororwa.

（3）Kugona Kushandiswazve: Kurarama maitiro akawanda mukushandiswa senge simbi kana kugadzirwa kwegirazi pasina kuora.

5. Kugadzirisa Zvido Zvakasiyana

Machubhu ekudzivirira eSiC anochinjika kumatambudziko enzvimbo kuburikidza neinjiniya yakagadzirwa:

（1）Magadzirirwo eHybrid: Anoshandiswa pamwe chete nesimbi kana zveceramics pakugadzira zvinhu zvakawanda (semuenzaniso zvinobatanidza shinda, maflange).

（2）Kugadziriswa kwePamusoro: Mukati makagadzirwa kuti mushandise magirazi kana kunze kwakagadzirwa kuti muwedzere kupisa.

（3）Kuchinjika kweSaizi: Yakagadzirwa kubva pamamirimita (mareactors ekurabhoritari) kusvika pamamita (makinu eindasitiri).

6. Kurongeka Kwekuchengetedza Nguva Dzekugara

Machubhu eSiC anotsigira maitiro emaindasitiri asingakuvadzi nharaunda:

（1）Kuchengetedza Simba: Kushanda nesimba zvakanyanya mukupisa kunoderedza kushandiswa kwemafuta muchoto kusvika ku20% zvichienzaniswa nesimbi dzinodzivirira.

（2）Kuderedza Marara: Nguva refu yekushanda inoderedza marara ezvinhu kubva pakugadziriswa nguva nenguva.

（3）Kuderedza Huturu: Bvisa kudiwa kwezvipfeko zvine njodzi (semuenzaniso, ma alloys akavakirwa pa nickel) munzvimbo dzinoparadza.

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.
