Iimpumlo zeSitshisi seSilicon Carbide (SiC)

Inkcazo emfutshane:

Kwiinkqubo zobushushu obuphezulu apho ulawulo lolwelo, ukumelana nokukhukuliseka, kunye nokuzinza kobushushu kubalulekile, ii-nozzles ze-silicon carbide (SiC) zibonakala njengommangaliso wobunjineli. Ngokungafaniyo nee-nozzles ze-ceramic okanye zesinyithi, iipropati ezikhethekileyo ze-SiC zijongana nemingeni kwiinkqubo zokutsha, ukuqhutywa, kunye nokutshiza kwemizi-mveliso. Eli nqaku liphonononga isizathu sokuba amashishini asebenzise ngakumbi ii-nozzles ze-SiC ukuguqula ukusebenza kwezicelo ezifuna kakhulu. 1. Yenzelwe i-Extreme Fluid Environm...

Iithegi zeMveliso

Kwiinkqubo zobushushu obuphezulu apho ulawulo lolwelo, ukumelana nokukhukuliseka, kunye nokuzinza kobushushu kubalulekile,ii-nozzles ze-silicon carbide (SiC)Zibonakala zingummangaliso wobunjineli. Ngokungafaniyo neempumlo zeceramic okanye zesinyithi, iipropati ezikhethekileyo zeSiC zijongana nemingeni kwiinkqubo zokutsha, ukuqhutywa, kunye nokutshiza kwimizi-mveliso. Eli nqaku liphonononga isizathu sokuba amashishini asebenzisa ngakumbi iimpumlo zeSiC ukuze aguqule ukusebenza kwezona zicelo zinzima.

1. Yenzelwe iiNdawo eziNamanzi agqithisileyo

Ii-nozzles ze-SiC zibalasele ekulawuleni isantya esiphezulu, ulwelo kunye neegesi ezishushu kakhulu:

（1）Ukumelana nokuKhukuliseka: Ukumelana namasuntswana arhabaxa kwii-injectors ze-coal slurry, iinkqubo ze-sandblasting, okanye ii-rocket propellants ngaphandle kokuguqulwa okubangelwa kukuguguleka.

（2）Ukusinda Kokutsha Kwe-Thermal Shock: Ijikeleza ngokukhawuleza phakathi kwamaqondo obushushu agqithisileyo (umz. ukufakwa kwepetroli kwii-oven ze-metallurgical) ngaphandle kokuqhekeka, ngenxa yokwanda okuphantsi kobushushu be-SiC.

（3）Ukungangeni Kwekhemikhali: Melana nokugqwala okuvela kwizitshizi ze-asidi/ze-alkaline, iityuwa ezinyibilikisiweyo, okanye amadangatye akhupha i-oxidizing, ukuqinisekisa ukuba i-orifice geometry iyafana.

2. Ulawulo lokuHamba ngokuLungileyo kwiiNkqubo eziBalulekileyo

Kwizicelo ezifuna ukuchaneka kwinqanaba le-micron, ii-nozzles ze-SiC zibonelela ngokuthembeka okungenakuthelekiswa nanto:

（1）Ijiyometri ye-Stable Orifice: Gcina amazinga okuhamba achanekileyo kunye neepateni zokutshiza nokuba sele ubekwe kwindawo eshushu ixesha elide kwi-1500°C+, ngokungafaniyo neentsimbi ezigobileyo okanye iiseramikhi eziwohlokayo.

（2）Ukuncitshiswa kokuvaleka: Ukugqitywa komphezulu okugudileyo kakhulu kunciphisa ukwakheka kwezinto kwii-injectors zepetroli okanye kwiinkqubo zokutshiza ngeekhemikhali.

（3）Ukunyamezelana noxinzelelo oluphezulu: Ukumelana noxinzelelo lwe-hydraulic oludlula i-500 MPa, ilungele ukusika i-waterjet okanye ukuqhuba ngenqwelo moya.

3. Ukuvumela ukutsha okusebenzayo kakhulu

Ii-nozzles ze-SiC zibaluleke kakhulu ekuphuculeni iinkqubo zokutsha ezisebenzisa amandla amaninzi:

（1）Uzinzo lweLanga: Uyilo olumelana nobushushu luqinisekisa ukuxubana komoya kunye namafutha kwiiturbine zegesi okanye kwiindawo zokutshisa igesi zoshishino, okunciphisa iindawo ezishushu kunye nokukhutshwa kwe-NOx.

（2）Ukuguquguquka kweFuel: Iyahambelana nehydrogen, i-biofuels, okanye iioyile ezinzima, ixhasa ukutshintshela kwimithombo yamandla ezinzileyo.

（3）Ukusebenza kakuhle kobushushu: Nciphisa ukulahleka kobushushu kwiindonga ngenxa yokuqhuba okuphezulu kobushushu beSiC, uphucule ukusebenza kakuhle kwegumbi lokutsha ukuya kuthi ga kwi-15%.

Ngaphambili: Iiplastiki ze-silicon carbide ceramic

Okulandelayo: Iityhubhu ze-silicon carbide ezikhazimlayo

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zinkulu zezinto ezintsha ze-silicon carbide ceramic eTshayina. I-SiC technical ceramic: Ubunzima bukaMoh buyi-9 (Ubunzima bukaMoh obuyi-13), bunokumelana okuhle nokukhukuliseka kunye nokugqwala, ukukrala okugqwesileyo - ukumelana nokubola kunye nokuchasana ne-oxidation. Ubomi benkonzo yemveliso yeSiC bubude obuphindwe ka-4 ukuya ku-5 kune-92% ye-alumina material. I-MOR ye-RBSiC iphindwe ka-5 ukuya ku-7 kune-SNBSC, ingasetyenziselwa iimilo ezinzima ngakumbi. Inkqubo yokucaphula iyakhawuleza, ukuhanjiswa kunjengoko kuthembisiwe kwaye umgangatho awulingani. Sihlala siqhubeka nokuchasa iinjongo zethu kwaye sibuyisela iintliziyo zethu kuluntu.
