Iilinki zeseramikhi ezingagugiyo zibonelela ngokhuseleko oluhle kakhulu oluchasene nokuguguleka kunye nokungaguguleki. Zakhelwe ngokukodwa ukusetyenziswa naphi na apho ukuguguleka nokungaguguleki kuyingxaki, iilininki zeZPC® zinciphisa ixesha lokungasebenzi kunye nokugcinwa kwazo. Iilininki zeseramikhi zeSiC zixhathisa kakhulu kwimiphumo yokuguguleka kwezinto ezininzi ezifana ne-silica, i-ore, iglasi, i-slag, i-fly ash, i-limestone, amalahle, i-coke, ukutya, iinkozo, isichumisi, ityuwa kunye nezinye izinto eziguguleka kakhulu.
Iilinings ezimelana nokukrala kunye nokuguguleka ezivela eZhongpeng zilungele amashishini amaninzi. Abathengi baqala kwishishini lempuphu ukuya kwishishini lamalahle, umbane, imigodi kunye nokutya apho ii-nozzles ze-FGD zivunyiweyo ukuba zisetyenziswe kwiChina Electric Power Group. Iilinings ezimelana nokukrala ze-ZPC zithengiswa kulo lonke elase-United States, eKhanada, e-Australia, eMexico, eMzantsi Afrika, njl. Zilungele izinto zelining ezichaphazeleka kukukrala okukhulu kwimisebenzi yokuphatha nokucubungula izinto zezityalo. Iilinings zeSiC, iipleyiti kunye neebhloko zisebenza kakuhle kwizicelo ezifana neepayipi, ii-tee, iingqiniba, izahluli, ii-cyclone, ii-silos, ii-bunkers, ii-tawrs zekhonkrithi kunye nentsimbi, ii-chutes, ii-impellers kunye nee-agitators, ii-fan blades kunye nee-fan casings, ii-conveyor screws, ii-chain conveyors, ii-mixers, ii-pulpers; naphi na apho ukukrala okubangelwa kukukrala kuyinkinga.
Iithayile ezimelana nokuguguleka ukuze zikhusele ukuguguleka, ukuhlangabezana neengxaki zomthengi ezithile zokuguguleka, impembelelo kunye nokugqwala. Ukusetyenziswa kwee-linings ezimelana nokuguguleka ze-ZPC SiC kwiindawo ezinengxaki kongeza ukonga okukhulu ngenxa yobomi bazo obude benkonzo. Iindleko zeendawo ezitshintshwayo, ixesha lokungasebenzi, ukucoca izityalo kunye neendleko zomsebenzi wokulungisa zonke zincitshiswe kakhulu. Ukonga okufunyenweyo kuya kuhlawulela ii-linings kunye nokufakwa kwazo ngexesha elifutshane.
I-silicon carbide sic bushing luhlobo olutsha lwezinto zobugcisa obuphezulu nezinganyangekiyo ehlabathini. Yenziwe nge-silicon carbide powder ecocekileyo kakhulu, i-carbon black eshushu kakhulu kunye nee-binders, ngokugalela, ukuvala, ukucola, kunye neenkqubo zokususa isanti, ezenziwe ngemveliso edibeneyo egudileyo.
Okwangoku isetyenziswa njenge-bushing kwizixhobo zemigodi, ezifana nobhedu, igolide, i-iron ore, i-nickel ore kunye nezinye kwi-non-ferrous metals. Idlala indima yokumelana nokuguguleka okuphezulu, ubomi bokuguguleka bungaphezulu kwe-10 kunobo be-steel bushings eqhelekileyo kunye ne-alumina bushing.
1. Ukusetyenziswa kwe-sic bushing kushishino lwezemigodi
Kwimibhobho yokuzalisa imigodi, umgubo oxutyiweyo kunye nothutho lweentsinga zombhobho zinokonakala okukhulu. Ubomi benkonzo yombhobho ohambisa umgubo we-ore owawusetyenziswa ngaphambili bungaphantsi konyaka omnye, kwaye ngoku ii-bushings ze-silicon carbide zinokunyusa ubomi benkonzo ngaphezu kwamaxesha ali-10.
2. Kutheni ii-linings ze-silicon carbide zisetyenziswa kakhulu kushishino lwezemigodi?
Ngenxa yokumelana nokuguguleka kweetyhubhu zeseramikhi, okulandelayo kuthelekiswa ukumelana nokuguguleka kweetyhubhu zeseramikhi nezinye izinto.

5. Uqhagamshelo lwe-silicon carbide bushing
（1）Xa iipayipi eziguquguqukayo zisetyenziselwa ukudibanisa iipayipi zokufakela, ubude bokufakelwa kweziphelo ezibini zesingxobo sepayipi eguquguqukayo kufuneka bulungiswe ngokulinganayo. Umsantsa wokwandiswa kufuneka usekelwe kwiimeko zasekuhlaleni okanye kwiimfuno zesebe loyilo.
（2）Xa usebenzisa uqhagamshelo lweflange, ubuso beflange kufuneka bube mhlophe kunye nobuso bombhobho odibeneyo
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.
