Kwintsimi yemveliso yoshishino, ukukhetha izinto ezifanelekileyo ze-ceramic kufana nokufumana amaqabane athembekileyo - kufuneka axhathise uvavanyo lwexesha, ukumelana nokusingqongileyo okugqithisileyo, kwaye uqhubeke nokongeza ixabiso ekusebenzeni kwemveliso. Unokwenza njani ukhetho olulumkileyo phambi koluhlu oluqaqambileyo lweemveliso ze-ceramic zoshishino? Eli nqaku liza kutyhila izinto eziphambili zokukhetha izinto zobuchwephesha kunye nokugxila ekuhlalutyeni iingenelo ezizodwa zei-silicon carbide ceramics, eyaziwa ngokuba "sisikrweqe soshishino".
1, Imithetho emithathu yeGolide yokukhetha iiCeramics zeShishini
1. Idigri yokulinganisa ukusebenza: Okokuqala, kuyimfuneko ukucacisa iimfuno eziphambili zemeko yokusetyenziswa. Ingaba yindawo yobushushu obuphezulu kakhulu? Umthombo owomeleleyo wokutya? Okanye ukukhuhlana koomatshini be-high-frequency? Kanye njengokukhetha izixhobo zokukhwela intaba ukwahlula phakathi kwekhephu kunye nentlango, iimeko ezahlukeneyo zokusebenza zifuna imathiriyeli yeceramic eneempawu ezihambelanayo.
2. Umjikelo wobomi benkonzo: Ixabiso leekeramics ezikumgangatho ophezulu libonakaliswa ekusebenziseni ixesha elide. Akufunekanga sinikele ingqalelo kuphela kwiindleko zokuqala zokuthengwa kwempahla, kodwa sibale iindleko ezifihlakeleyo ezibangelwa kukugcinwa nokutshintshwa kwamaxesha. Ngokwenene iiseramics ezikumgangatho ophezulu kwimizi-mveliso kufuneka zithembeke “njengezinto zasimahla zokulondolozwa”.
3. Ubuchule benkxaso yobugcisa: Ababoneleli abagqwesileyo abanako ukubonelela ngeemveliso eziqhelekileyo kuphela, kodwa baphinde baphucule iifomyula kunye nezakhiwo zokuyila ngokusekelwe kwiimeko ezithile zokusebenza, ezihlala zigqiba ukusebenza kokugqibela kwezixhobo kwizicelo eziphathekayo.
2. Iingenelo ezine eziphambili zokusebenza kwe-silicon carbide ceramics
Njengomathiriyeli weenkwenkwezi zeeseramics zale mihla, iiseramics zesilicon carbide ziba lolona khetho lukhethwayo kumashishini amaninzi nangakumbi. Ukudityaniswa kwayo okukhethekileyo kokusebenza kunokubizwa ngokuba "ligorha eline-hexagonal" lezinto zoshishino:
1. Isikrweqe esomeleleyo esihlala sihleli: Ubume bekristale bunika ubulukhuni besibini kuphela kwidayimane, enokwandisa ngokufanelekileyo ubomi benkonzo yezixhobo kwiimeko ezifana neenkqubo zokuhambisa ezigxininisiweyo kunye neebheringi ezichanekileyo.
2. Ikhaka elikhuselayo leMichiza: Inokumelana okugqwesileyo kwi-acids eqinile, isinyithi esinyibilikisiweyo, njl., kwaye ifaneleke ngokukodwa kwiindawo ezinobungozi ezifana nemikhumbi yokusabela kweekhemikhali kunye neenkqubo ze-industrial desulfurization, ukuphepha ukungcola okuphakathi okubangelwa ukulahlekelwa kwezinto eziphathekayo.
3. I-Thermal Stability Guardian: Iyakwazi ukugcina ukuzinza kwesakhiwo nakwiqondo lokushisa eliphezulu le-1350 ℃, kunye ne-coefficient yokwandisa i-thermal kuphela i-1/4 yentsimbi, okwenza kube yinto efanelekileyo yokukhetha i-kilns ephezulu kunye ne-spacecraft yokukhusela i-thermal systems.
4. Ingcali ekhaphukhaphu: Ngoxinaniso lwesinye kwisithathu kuphela sentsimbi, inokubonelela ngokufanayo okanye nangaphezulu amandla omatshini, kwaye ineenzuzo ezicacileyo kwizixhobo ezizenzekelayo kunye neendawo ezintsha zamandla ezifuna ukunciphisa ubunzima kunye nokuphucula ukusebenza kakuhle.
3, Iingcebiso zokukhetha izinto eziphambili
Ukongeza kwiiparameters ezisisiseko, kuyacetyiswa ukuba ugxininise kwiinkcukacha zenkqubo ezifana nokufana kwe-microstructure yezinto eziphathekayo kunye nokugudiswa komhlaba. Ezi 'mpawu zingabonakaliyo' zihlala zimisela ukusebenza kwemathiriyeli kumazwe abalulekileyo.
Ukukhetha i-ceramics yezoshishino ngokusisiseko ukhetha "umlindi" womgca wemveliso. I-Silicon carbide ceramics, kunye nendibaniselwano yabo ekhethekileyo yepropati, iphinda ichaze ukuqonda ukuthembeka kwimveliso yoshishino. Xa ujongene nemiceli mngeni enzima yokusebenza, vumela lo mdlali uguquguqukayo kushishino lwezixhobo zakhele umgca wokuzikhusela owomeleleyo.
Siye sabandakanyeka ngokunzulu kwintsimi ye-silicon carbide ceramics iminyaka engaphezu kweshumi, sigxile ekuboneleleni izisombululo zezinto eziphathekayo kubathengi. NdwendwelaShandong Zhongpengukufumana idatha elinganisiweyo ngakumbi kwiimeko zesicelo, okanye uqhagamshelane neqela lethu lobunjineli ukuze wenze ngokwezifiso izisombululo zokukhetha izinto.
