Umbhobho we-ceramic we-silicon carbide onganyangekiyo
I-silicon carbide ceramic: Ubunzima bukaMoh buyi-9.0 ~ 9.2, bunokumelana okuhle nokukhukuliseka kunye nokugqwala, buyakwazi ukumelana nokukrweleka kunye nokulwa ne-oxidation. Bunamandla ngokuphindwe ka-4 ukuya ku-5 kune-nitride bonded silicon carbide. Ubomi benkonzo bude ngokuphindwe ka-7 ukuya ku-10 kune-alumina material. I-MOR ye-RBSiC iphindwe ka-5 ukuya ku-7 kune-SNBSC, ingasetyenziselwa iimilo ezintsonkothileyo ngakumbi.
Ukumelana nokuguguleka kwe-silicon carbide, yenziwe nge-silicon carbide kunye ne-carbon kubushushu obuphezulu, iyinxalenye yohlobo lwemveliso ye-silicon carbide. Iindawo zokuxhathisa ukuguguleka kwe-silicon carbide zisetyenziswa kakhulu kwimigodi, ekutyumzeni i-ore, ekuhlolweni nasekuthuthweni kokuguguleka okuphezulu, ulwelo olune-corrosive ephezulu, ikwalungele kakhulu iimveliso zoomatshini ezineemfuno ezichanekileyo nezitywiniweyo, ezifana nepompo yoxinzelelo oluphezulu, ipompo yemagnethi njl.njl. Luhlobo olutsha lwezinto zokuxhathisa ukuguguleka. I-bushing ye-silicon carbide ebophelelwe yi-reaction-bonded ineempawu zobulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu, ukumelana nempembelelo, ukumelana nobushushu obuphezulu, ukumelana ne-asidi kunye nokugqwala kwe-alkali njalo njalo, kwaye ubomi benkonzo bokwenyani bungaphezulu kwe-6 ye-polyurethane. Ifanelekile ngokukodwa ekusebenzeni kohlulo, ukugxila kunye nokuphelelwa ngamanzi kwezinto ezinamandla ezirhabaxa nezirhabaxa, isetyenziswe ngempumelelo kwimigodi emininzi. Inkampani yethu ngumthengisi weemveliso ze-ceramic ze-silicon carbide zobungcali, ubunzima bulandela idayimani, bunokumelana nokuguguleka okuphezulu, iimpawu zobomi obude. Umbhobho wokuxhathisa ukuguguleka kunye nengqiniba eveliswe nge-lining ye-silicon carbide yokuguguleka, ubukhulu bayo be-lining ye-ceramic yi-6-35mm, isakhiwo senzelwe ukufaka esele ikhona. Ityhubhu yeseramikhi efakwe kwityhubhu yentsimbi ehambelanayo, kunye neglu embindini. Iipayipi zeseramikhi ezimelana nokunxitywa zineempawu ezilandelayo xa kuthelekiswa neepayipi zelitye eliqingqiweyo ezazisetyenziswa ngaphambili, iipayipi zesinyithi ezixutyiweyo ezinganyangekiyo kunye neepayipi zeseramikhi ezidityanisiweyo.
I-Reaction bonded silicon carbide (RBSC) ine-peformance egqwesileyo enganyangekiyo, iipropati ezilungileyo kumaqondo obushushu aphezulu, ukukhukuliseka okuhle kunye nokumelana nokurhawuzelela, ezi mpawu zingasetyenziswa kwiindlela ezahlukeneyo zokusebenza ezifana neepayipi, i-ceramic elbow, ii-spray nozzles, ii-shot blast nozzles kunye nee-hydrocyclone components.
Iilinki ze-ZPC zihlala ixesha elide kunee-liner zethayile nezesinyithi. Iiceramics ze-ZPC silicon carbide ziyamelana nobushushu kunye nokurhawuzelelwa kokukrweleka nto leyo ebangela ukuba ixesha lokusebenza lide kwaye linciphe.
I-reaction bonded silicion carbide ceramic (RBSIC) yinto efanelekileyo yokumelana nokuguguleka, efanelekileyo ngokukodwa kwi-abrasive enamandla, amasuntswana arhabaxa, ukwahlulahlula, uxinaniso, ukuphelelwa ngamanzi emzimbeni kunye neminye imisebenzi. Ngenxa yeempawu ezingentla,I-elbow / ityhubhu ye-liner ye-RBSiC / SiSiC ye-silicon carbideingakhusela ngempumelelo inxalenye ekugugulekeni okuphezulu kunye nobushushu ukuze yandise ubomi benkonzo yesixhobo.
