Kwicandelo lemveliso yemizi-mveliso, ukukhetha izixhobo zeseramikhi ezifanelekileyo kufana nokufumana amaqabane athembekileyo - kufuneka imelane novavanyo lwexesha, imelane neemeko ezinzima, kwaye iqhubeke nokongeza ixabiso ekusebenzeni kakuhle kwemveliso. Ungayenza njani ukhetho olulumkileyo xa ujongene noluhlu oluhle lweemveliso zeseramikhi zemizi-mveliso? Eli nqaku liza kutyhila izinto ezibalulekileyo zokukhetha izixhobo zobungcali kwaye ligxile ekuhlalutyeni iingenelo ezikhethekileyo zeiiseramikhi zesilicon carbide, eyaziwa ngokuba “sisikrweqe semizi-mveliso”.
1, Imithetho Emithathu Yegolide Yokukhetha Iiseramikhi Zemizi-mveliso
1. Izinga lokufanisa ukusebenza: Okokuqala, kuyimfuneko ukucacisa iimfuno eziphambili zemeko yokusetyenziswa. Ngaba yindawo enobushushu obuphezulu kakhulu? Ngaba yindawo enamandla yokubola? Okanye ukungqubana koomatshini okuphindaphindekayo? Njengokukhetha izixhobo zokunyuka intaba ukuze kwahlulwe phakathi kwekhephu nentlango, iimeko zokusebenza ezahlukeneyo zifuna izinto zeseramikhi ezineempawu ezifanayo.
2. Umjikelo wobomi benkonzo: Ixabiso le-ceramics ezisemgangathweni ophezulu libonakala ekusetyenzisweni kwexesha elide. Asifanele siqwalasele kuphela iindleko zokuthenga zokuqala, kodwa sikwabale neendleko ezingacacanga ezibangelwa kukugcinwa rhoqo kunye nokutshintshwa. Ii-ceramics zoshishino ezisemgangathweni ophezulu kufuneka zithembeke njenge "zinto ezingenazo izinto zokugcinwa".
3. Amandla okuxhasa ubugcisa: Ababoneleli ababalaseleyo abanakubonelela ngeemveliso ezisemgangathweni kuphela, kodwa banokuphucula iifomyula kunye noyilo lwezakhiwo ngokusekelwe kwiimeko ezithile zokusebenza, ezihlala zimisela ukusebenza kokugqibela kwezixhobo kwizicelo ezisebenzayo.
2, Iingenelo ezine eziphambili zokusebenza kweeseramikhi zesilicon carbide
Njengezinto eziphambili kwiiseramikhi zanamhlanje zoshishino, iiseramikhi ze-silicon carbide ziba lukhetho olukhethwayo kumashishini amaninzi. Indibaniselwano yayo yokusebenza eyahlukileyo inokubizwa ngokuba "yimfazwe enama-hexagonal" yezinto zoshishino:
1. Isikrweqe esiqinileyo: Isakhiwo sekristale sisinika ubulukhuni obungaphezulu kwedayimani, obunokwandisa ubomi benkonzo yezixhobo kwiimeko ezifana neenkqubo zokuhambisa ezixineneyo kunye neebheringi ezichanekileyo.
2. Ikhaka elikhuselayo leekhemikhali: Linokumelana okuhle kakhulu nee-asidi ezinamandla, iintsimbi ezinyibilikisiweyo, njl.njl., kwaye lifanelekile ngokukodwa kwiindawo ezirhabaxa ezifana neenqanawa zokusabela kweekhemikhali kunye neenkqubo zokususa i-sulfurization kwimizi-mveliso, liphepha ungcoliseko oluphakathi olubangelwa kukulahleka kwezinto.
3. Umkhuseli woZinzo loBushushu: Ingagcina uzinzo lolwakhiwo nokuba kumaqondo obushushu aphezulu angama-1350 ℃, kunye ne-1/4 yentsimbi enomlinganiselo wokwandisa ubushushu, nto leyo eyenza ukuba ibe lolona khetho lufanelekileyo kwii-ovens ezinobushushu obuphezulu kunye neenkqubo zokukhusela ubushushu beenqwelo-moya.
4. Ingcali ekhaphukhaphu: Ngobuninzi obuyi-1/3 kuphela bentsimbi, inokubonelela ngamandla oomatshini afanayo okanye aphezulu, kwaye ineenzuzo ezicacileyo kwizixhobo zokwenza izinto ngokuzenzekelayo kunye namacandelo amatsha amandla afuna ukunciphisa ubunzima kunye nokuphuculwa kokusebenza kakuhle.
3, Iingcebiso zokukhetha izinto eziphambili
Ukongeza kwiiparameter ezisisiseko, kuyacetyiswa ukuba kugxilwe kwiinkcukacha zenkqubo ezifana nokufana kwesakhiwo sezinto ezincinci kunye nokuguda komphezulu. Ezi 'mpawu zingabonakaliyo' zihlala zimisela ukusebenza kwezinto kwiimeko ezibalulekileyo.
Ukukhetha iiseramikhi zoshishino ngokuyintloko kukukhetha "umlindi" womgca wemveliso. Iiseramikhi ze-silicon carbide, kunye nomxube wazo okhethekileyo weempawu, zichaza ngokutsha ukuqonda ukuthembeka kwimveliso yezimboni. Xa ujongene nemingeni yokusebenza enzima, vumela lo mdlali oguquguqukayo kwishishini lezinto zokwakha akhe umgca wokuzikhusela oqinileyo kuwe.
Besibandakanyeke kakhulu kwicandelo le-silicon carbide ceramics kangangeminyaka engaphezu kweshumi, sigxile ekuboneleleni ngezisombululo zezinto ezenziwe ngokwezifiso kubathengi.Shandong Zhongpengukuze ufumane idatha ethe kratya elinganisiweyo kwiimeko zesicelo, okanye unxibelelane neqela lethu lobunjineli ukuze wenze ngokwezifiso izisombululo zokukhetha izinto ezilungele wena.
