Nxiba iileyile zeceramic ezixhathisayo zibonelela ngempembelelo ebalaseleyo kunye nokhuseleko oluxhathisayo lwe-abrasion. Eyakhelwe ngokukodwa ukuba isetyenziswe naphi na apho ukunxiba kunye ne-abrasion kuyingxaki, i-ZPC® linings inciphisa ixesha lokuphumla kunye nokugcinwa. I-SiC ye-ceramic linings ixhathisa kakhulu kwimiphumo enobungozi bezinto ezininzi ezifana ne-silica, i-ore, iglasi, i-slag, i-fly ash, i-limestone, amalahle, i-coke, isondlo, ingqolowa, isichumisi, ityuwa kunye nezinye izinto ezinobungozi kakhulu.
Ukumelana ne-Abrasion kunye nokunxiba iileyile ezixhathisayo ezivela eZhongpeng zilungele amashishini amaninzi. Abathengi bavela kwishishini lomgubo ukuya kumalahle, amandla, umgodi kunye namashishini okutya apho imilomo ye-FGD ivunyiwe ukuba isetyenziswe kwi-China Electric Power Group. I-ZPC yokunxiba iileyile ezixhathisayo zithengiswa kulo lonke elase-United States, eKhanada, eOstrilia, eMexico, eMzantsi Afrika, njl. I-SiC linings, iipleyiti kunye neebhloko zisebenza ngokufanelekileyo kwizicelo ezinjengemibhobho, iiteyi, ingqiniba, izahluli, iinkanyamba, iisilos, iibhankere, ikhonkrithi kunye nemikhombe yentsimbi, ii-chutes, ii-impellers kunye ne-agitators, iiblade zefeni kunye nezikrufu zefeni, izikrufu zokuhambisa, iintambo zokuhambisa, imixube, naphi na apho i-friction-induced abrasion yingxaki.
Iithayile ezixhathisa i-abrasion zokukhusela ukunxiba, ukuhlangabezana ne-abrasion ethile yomthengi, impembelelo kunye neengxaki zokubola. Ukusetyenziswa kwe-ZPC SiC ukunxiba iileyile ezixhathisayo kumalungu anengxaki yongeza ukonga okubalulekileyo ngenxa yobomi babo obude benkonzo. Iindleko zokutshintshwa kwamalungu, ixesha lokungasebenzi, ukucocwa kweplanti kunye neendleko zomsebenzi wokulondoloza zonke zincitshiswe kakhulu. Ugcino olwenziweyo luya kuhlawula ii-linings kunye nokufakwa ngexesha elifutshane.
I-Silicon carbide sic bushing luhlobo olutsha lwetekhnoloji ephezulu kunye nezinto ezinganxiliyo kwihlabathi. Yenziwe nge-silicon carbide powder ecocekileyo ephezulu-yomgangatho ophezulu wobushushu obuphezulu bekhabhoni emnyama kunye nezibophelelo, ngokugalela, ukuvala, ukucoca, kunye neenkqubo zokususa isanti, ezenziwe ngemveliso edityanisiweyo yokunxiba.
Ngoku isetyenziswa njengesihlahla kwizixhobo zemigodi, ezinje ngobhedu, igolide, intsimbi ekrwada, i-nickel ore kunye nezinye kwiintsimbi ezingenayo i-ferrous.Idlala indima yokumelana nokunxiba okuphezulu, ubomi bokunxiba bungaphezulu kwamaxesha ali-10 eentsimbi eziqhelekileyo kunye ne-alumina bushing.
1.Ukusetyenziswa kwe-sic bushing kushishino lwemigodi
Ukuzaliswa kwemigodi, i-powder concentrate kunye ne-tailings transportation igugile kakhulu kumbhobho.Ubomi benkonzo yombhobho we-ore ohambisa umgubo osetyenziswe ngaphambili ungaphantsi konyaka omnye, kwaye ngoku khetha i-silicon carbide bushings inokunyusa ubomi benkonzo ngamaxesha angaphezu kwe-10.
2.Kutheni i-silicon carbide linings isetyenziswa ngokubanzi kwishishini lemigodi?
Ngenxa yokunganyangeki kweetyhubhu ze-ceramic, oku kulandelayo kuthelekiso lokunganyangeki kweetyhubhu ze-ceramic kunye nezinye izinto.

5.Silicon carbide uqhagamshelo bushing
(1) Xa iibhobho eziguquguqukayo zisetyenziselwa ukudibanisa imibhobho yokufakela, ubude bokufakwa kweziphelo ezimbini zombhobho oguquguqukayo kufuneka zilungiswe ngokulinganayo. Umsantsa wokwandisa kufuneka usekelwe kwiimeko zendawo okanye iimfuno zesebe loyilo.
(2) Xa usebenzisa uxhulumaniso lweflange, ubuso beflange kufuneka bugungxulwe kunye nesiphelo sombhobho odibeneyo.
I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubulukhuni be-Moh yi-9 (ubulukhuni be-Moh entsha yi-13), kunye nokuchasana okugqwesileyo kukhukuliseko kunye nokugqwala, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
