Nxiba i-ceramic exhathisayoi-linings inika impembelelo egqwesileyo 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-Linings ye-SiC, iipleyiti kunye neebhloko zisebenza ngokufanelekileyo kwizicelo ezinjengemibhobho, iiteyi, ingqiniba, izahluli, iinkanyamba, iisilo, iibhankere, ikhonkrithi kunye nemikhombe yentsimbi, ii-chutes, ii-impellers kunye ne-agitators, iiblades zefeni kunye nee-fan casings, izikrufu zokuhambisa, izikhonkwane zokuhambisa; abaxube, iipulpers; 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.
Kungoku nje isetyenziswa njengesihlahla kwizixhobo zemigodi, ezinje ngobhedu, igolide, intsimbi ekrwada, i-nickel ore kunye nezinye kwiintsimbi ezingezizo i-ferrous. Idlala indima yokumelana nokunxiba okuphezulu, ubomi bokunxiba bungaphezulu kwamaxesha ali-10 kobuqhelekileyo. iintsimbi zentsimbi kunye ne-alumina bushing.
1.Ukusetyenziswa kwe-sic bushing kushishino lwemigodi
Ukuzaliswa kwemigodi, uthutho lwe-powder concentrate kunye ne-tailings lugugile kakhulu kumbhobho. Ubomi benkonzo yombhobho ogqithisa umgubo we-ore owawusetyenziswa kwixesha elidlulileyo ungaphantsi konyaka omnye, kwaye ngoku khetha i-silicon carbide bushings inokunyusa ubomi benkonzo ngaphezu koku. 10 amaxesha.
2.Kutheni i-silicon carbide linings isetyenziswa ngokubanzi kwishishini lemigodi?
Ngenxa yokumelana nokunxiba kweityhubhu ye-ceramics, ilandelayo luthelekiso lokunxiba ukumelanaityhubhu ye-ceramics kunye nezinye izixhobo.

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.
