Izicelo ze-silicon carbide ceramic

1, 'Amandla amakhulu' kaiiseramikhi zesilicon carbide
(1) Ubulukhuni obuphezulu, abugugi kwaye buhlala ixesha elide
Ubunzima bee-silicon carbide ceramics buphakathi kwezona ziphambili kushishino lwezinto, bulandela idayimani kuphela. Oku kuthetha ukuba inokumelana nokuguguleka okukhulu. Umzekelo, ukuba sithelekisa izinto eziqhelekileyo nezihlangu eziqhelekileyo, ziya kuguga kakhulu emva kokunxiba ixesha elifutshane; Loo silicon carbide ceramic ifana neebhutsi zobuchwephesha zokuhamba ngeenyawo zangaphandle, nokuba iphoswa nzima kangakanani na, akulula ukuyiqhekeza. Njengezinye izinto zoomatshini, izinto eziqhelekileyo zinokuguguleka ngokukhawuleza phantsi kokusebenza ngesantya esiphezulu kunye nokungqubana rhoqo. Nangona kunjalo, ukuba kusetyenziswa ii-silicon carbide ceramics, ubomi bazo benkonzo bunokwandiswa kakhulu, ukuphindaphinda kokutshintshwa kwezinto kunokuncipha, kwaye ayibizi kakhulu kwaye ayinaxhala.
（2） Ukumelana nobushushu obuphezulu, ungoyiki "iNtaba yeFlame"
Khawuthelekelele ukuba kwindawo enobushushu obuphezulu be-1200 ℃, izinto ezininzi sele “zingakwazi ukumelana”, nokuba ziyanyibilika kwaye ziyaguquguquka, okanye ukusebenza kwazo kuncitshiswe kakhulu. Kodwa ii-silicon carbide ceramics zinokuhlala zingatshintshi ngembonakalo, zingagcini nje ngokugcina iipropati zomzimba nezikhemikhali ezizinzileyo, kodwa zide zifikelele kwi-1350 ℃, nto leyo ezenza “ukumkani wamandla obushushu obuphezulu” phakathi kwezinto ze-ceramic. Ngoko ke kwezinye iindawo zoshishino ezinobushushu obuphezulu, ezifana nezitofu ezinobushushu obuphezulu, izitshintshi zobushushu, amagumbi okutsha, njl.njl., ii-silicon carbide ceramics ngokungathandabuzekiyo zezona zinto zikhethwayo, ezinokusebenza ngokuzinzileyo kwiindawo ezinobushushu obuphezulu kwaye ziqinisekise imveliso egudileyo.
（3） Uzinzo lweekhemikhali, ukumelana neasidi kunye ne-alkali
Kwimveliso yeekhemikhali, umntu uhlala edibana neekhemikhali ezirhabaxa kakhulu ezifana nee-asidi ezinamandla kunye nee-alkali. Iiceramics ze-silicon carbide, ezinozinzo oluhle kakhulu lweekhemikhali, zifana nomaleko "wesigqubuthelo sentsimbi yegolide" phambi kwezi khemikhali, nto leyo eyenza ukuba zingachaphazeleki kakhulu kukurhabaxa. Oku kwenza ukuba idlale indima ebalulekileyo ekuvelisweni kwezixhobo zeekhemikhali, ezifana neepayipi ezimelana nokugqwala, iivalvu, iipompo, kunye nezinye izinto, ezinokumelana nokugqwala kwezinto zeekhemikhali kwaye ziqinisekise ukhuseleko kunye nokuzinza kwemveliso yeekhemikhali.

2. "Intsimi yokusebenza"iiseramikhi zesilicon carbide
（1） Ishishini leemishini: 'imodeli yomsebenzi' eqinileyo nengagugiyo
Kwinkqubo yokucubungula ngoomatshini, izixhobo ezahlukeneyo zokusika, iibheringi, iiringi zokuvala kunye nezinye izinto kufuneka zimelane nemithwalo ephezulu kunye nokuguguleka okubangelwa kukuhamba ngesantya esiphezulu. Ubunzima obukhulu kunye namandla e-silicon carbide ceramics kuzenza zibe zizinto ezifanelekileyo kwezi zinto. Izixhobo zokusika ezenziwe nge-silicon carbide ceramics zinokuphucula kakhulu ukuchaneka komatshini kunye nobomi bezixhobo, kwaye zinciphise iindleko zemveliso; iibheringi ze-silicon carbide ceramic kunye neeringi zokuvala zinokumelana okuhle nokuguguleka kunye nokusebenza kokuvala, ezinokusebenza ngokuzinzileyo kwiindawo zokusebenza ezinzima, zinciphise ukusilela kwezixhobo, kwaye ziphucule ukusebenza kakuhle kwemveliso.
（2） Ukususwa kwesalfur kwindalo esingqongileyo: "uvulindlela oluhlaza" ekunciphiseni ungcoliseko
Kwinkqubo yokususa i-sulfurization kwimizi-mveliso, izixhobo kufuneka zibekwe kwi-slurry enamandla ye-acid desulfurization ixesha elide, kwaye izixhobo eziqhelekileyo zibola kwaye zonakaliswe lula. Ii-silicon carbide ceramics, ezinozinzo lwazo oluhle kakhulu lweekhemikhali, azitshintshi kwiindawo ezine-acid kwaye zinokumelana ngempumelelo nokukhukuliseka kwe-slurries ye-desulfurization; Kwangaxeshanye, ubulukhuni bayo obuphezulu kakhulu kunye nokumelana nokuguguleka kunokugcina ukuthembeka kwezixhobo nokuba zijongene nokukhukuliseka okuvela kumasuntswana aqinileyo kwi-slurry. Izixhobo ezifana nee-nozzles ze-desulfurization kunye nemibhobho eyenziwe nge-silicon carbide ceramics azigcini nje ngokwandisa ubomi bazo benkonzo kwaye zinciphise ilahleko yexesha lokungasebenzi ezibangelwa kukutshintshwa rhoqo, kodwa zikwaqinisekisa ukusebenza kakuhle kwe-desulfurization, zinceda imveliso yemizi-mveliso ukuba ihambe phambili ngokufanelekileyo kwindlela eya kwimigangatho yokusingqongileyo.
（3） Ishishini leekhemikhali: 'umlindi okhuselayo' omelana nokugqwala
Kwimveliso yeekhemikhali, izixhobo kufuneka zinxibelelane rhoqo neentlobo ngeentlobo zezinto ezibangela ukubola kakhulu. Uzinzo oluhle kakhulu lweekhemikhali ze-silicon carbide ceramics lubenza bakwazi ukumelana nokukhukuliseka kwezi khemikhali. Kwizixhobo zeekhemikhali, ukusetyenziswa kwee-silicon carbide ceramics kwiindawo eziphambili ezifana neempompo, iivalvu, kunye nemibhobho kunokuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwezixhobo kwiindawo ezinobungozi beekhemikhali, ukunciphisa iindleko zokugcinwa kwezixhobo kunye nokutshintshwa kwazo, kunye nokuphucula ukhuseleko kunye nokuthembeka kwemveliso yeekhemikhali.
3, 'Ikamva elithembisayo'iiseramikhi zesilicon carbide
Ngenkqubela phambili eqhubekayo kunye nophuhliso lwetekhnoloji, amathuba okusetyenziswa kweeseramikhi ze-silicon carbide aya kuba banzi nangakumbi. Kwelinye icala, ngokuphuculwa okuqhubekayo kunye nobuchule bokulungiselela itekhnoloji, iindleko zemveliso yeeseramikhi ze-silicon carbide kulindeleke ukuba zincitshiswe ngakumbi, okuvumela ukuba zisetyenziswe kwiindawo ezininzi; Kwelinye icala, itekhnoloji edibeneyo yeeseramikhi ze-silicon carbide nezinye izinto nayo ikhula rhoqo. Ngokudibanisa iiseramikhi ze-silicon carbide nezinye izinto, izinto ezidibeneyo ezineempawu ezibalaseleyo zinokwenziwa ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
I-Shandong Zhongpeng, njengeshishini eligxile ekuveliseni iiseramikhi ze-silicon carbide, izibophelele ekuphandeni nasekuveliseni iimveliso zeseramikhi ze-silicon carbide ezikumgangatho ophezulu, isoloko ihlola ukusetyenziswa kweeseramikhi ze-silicon carbide kwiinkalo ezahlukeneyo. Sikholelwa ukuba iiseramikhi ze-silicon carbide, "iqhawe elikhulu" leshishini lezinto eziphathekayo, ziya kudala imimangaliso emininzi kuphuhliso lwetekhnoloji yexesha elizayo kunye nemveliso yemizi-mveliso, kwaye zenze igalelo elikhulu kwinkqubela phambili yoluntu.
