Imunzvimbo dzakanyanya kushata dzemaindasitiri—dzine tembiricha yakakwira, ngura, uye kuputsika kwesimbi yakanyungudutswa—kuchengetedzwa kwemidziyo kwakavimbika kwakakosha pakuchengetedza kushanda zvakanaka kwekugadzira uye kunaka kwechigadzirwa.Machubhu ekudzivirira eNitride bonded silicon carbide (NBSiC), chinhu chakagadzirwa zvine simba guru chakagadzirwa ne70-80% silicon carbide (SiC) uye 20-30% silicon nitride (Si₃N₄), chinosiyana zvikuru nezviratidzo zvaro: kudzivirira kupisa kwakanyanya kusvika 1450℃ (1650-1750℃ mumhepo chaiyo), kudzivirira ngura/abrasion kwakanyanya, kugadzikana kwakanyanya kwekupisa, uye kufambisa kupisa kwakanyanya.Heano mashandisirwo azvo makuru, zvichiratidza kuti zvinogadzirisa sei matambudziko makuru kune vagadziri vepasi rose.
1. Kudzivirirwa kweThermocouple: Kutarisa Tembiricha Nemazvo Mumamiriro Ezvinhu Akaoma
Kudzora tembiricha kwakakosha pamhando yepamusoro uye kuchengetedzeka kwemaindasitiri, uye mathermocouples ndiwo maturusi makuru ekuyera tembiricha. Zvisinei, mumaovheni anodziya zvakanyanya, masimbi anonyungudutsa asina ferrous, uye michina yekurapa kupisa, mathermocouples asina kudzivirirwa anokuvadzwa nyore nyore ne oxidation, ngura, kana simbi yakanyunguduka—zvichikonzera kuverenga kusina kururama, nguva isina kurongwa yekushanda, uye mari yakawanda yekugadzirisa.Machubhu ekudzivirira eNBSiC akagadzirwa kuti adzivirire mathermocouples, zvichiita kuti ave sarudzo yepamusoro yekutarisa tembiricha zvakanyanya.
Kuwanda kwavo kwekupisa kwakaderera (4.4×10⁻⁶/℃) uye porosity yakaderera (<1%) zvinoita kuti pave nekugadzikana kwezvikamu uye zvinodzivirira ngura kubva kumagasi ane acidic/alkaline uye simbi dzakanyungudutswa. Nekuomarara kweMohs ~9, vanoramba kupera simba kubva kuzvinhu zvidiki.Mashandisirwo makuru anosanganisira maovheni ekugadzira simbi, maovheni ekunyungudutsa aruminiyamu, uye maovheni eceramic, uko machubhu eNBSiC anowedzera hupenyu hwe thermocouple nekatatu kana kupfuura zvichienzaniswa nedzimwe nzira dzechinyakare.
2. Kunyungudutsa & Kukanda Simbi Isina Ferrous: Kudzivirira Maitiro Akakosha
Maindasitiri ekunyungudutsa/kukanda aruminiyamu, mhangura, uye zinc anotarisana nematambudziko makuru: kuputsika kwesimbi yakanyungudutswa uye njodzi dzekusvibiswa.Machubhu ekudzivirira eNBSiC ane mabasa maviri makuru pano, achipa mhinduro dzakagadzirirwa iwe.
a. Machubhu Akavharirwa Ekudzivirira Kupisa
Muzvitofu zvinonyungudutsa aruminiyamu, zvinhu zvinodziya zvesilicon carbide zvakakosha asi zviri nyore kukuvadzwa nearuminiyamu yakanyungudutswa.Machubhu eNBSiC akavharwa anoshanda sechidziviriro, achibvisa zvinhu zvinopisa kubva kusimbi yakanyungudutswa kuti zvirambe zvichirarama kwenguva refu uye kudzivirira kusvibiswa.Kufamba kwadzo mumhepo zvakanyanya kunoita kuti kupisa kupfuure zvakanaka, zvichideredza kushandiswa kwesimba. Dzinogona kugadziriswa mudhayamita (kusvika 600mm) uye kureba (kusvika 3000mm), dzinoenderana nemagadzirirwo akasiyana echoto.
b. Zvinosimudza zveAluminium Wheel Casting
Zvikwiriso zveNBSiC zvakavhurika (machubhu ekusimudza) zvinoita kuti aruminiyamu yakanyungudutswa ifambe kubva muzvitofu kuenda kumafuru ekugadzira mavhiri ealuminium. Nekutonhora kwemodulus yekuputika >150MPa uye kudzivirira kupisa kwakanyanya (kusingapfuuri ne100 cycles ye1000℃-room tembiricha), zvinoita kuti kuyerera kwakasimba, kurambe kuripo—kuderedza zvikanganiso zve casting (porosity, inclusions) uye kuwedzera goho. Kusiyana nemachubhu esimbi yakanyungudutswa, NBSiC haisvibisi aruminiyamu yakanyungudutswa, ichichengetedza kuchena kwechigadzirwa.
3. Mashandisirwo emakemikari nechoto: Kuramba ngura munzvimbo dzine hukasha
Mafekitori ekugadzira makemikari (petroleum cracking, acid/alkali production) uye ma ceramic/glass kilns anoshanda nemagasi anopisa uye tembiricha yakakwira.Machubhu eNBSiC anodzivirira masensa nezvinhu zvinodziisa pano, nekuda kwekusagadzikana kwengura.Muma reactors anopwanya petroleum, anodzivirira ngura yeH₂S neCO₂ pakupisa kwakanyanya; mumakiln eceramic/glass, anodzivirira ma thermocouples kubva mumhepo ine oxidative uye kubva pakusakara, zvichiita kuti tembiricha idzoke zvakanaka kune zvigadzirwa zvemhando yepamusoro.
Machubhu ekudzivirira eNBSiC anobatanidza kushanda zvakanaka kwemutengo nekushanda kwakasimba, zvichipa hupenyu hwebasa hurefu, dziviriro yemidziyo yakakosha, uye kugadzirisa zvinhu. Ingave iri mukugadzira simbi, kurapwa nekupisa, makemikari, kana simba idzva, anopa kuvimbika kunodiwa kuti urambe uchikwikwidzana.Taura nesu nhasi kuti uongorore mhinduro dzakagadzirirwa iwe pamatambudziko ako ekupisa kwakanyanya uye ngura.
