Dahaarka dhoobada ah ee u adkaysta xidhashada ayaa bixiya saameyn aad u fiican iyo ilaalin u adkaysta xoqidda. Si gaar ah loogu talagalay in loo isticmaalo meel kasta oo ay dhibaato ka jirto xirashada iyo xoqidda, dahaarka ZPC® wuxuu yareeyaa wakhtiga shaqada iyo dayactirka. Dahaarka dhoobada ah ee SiC waxay aad ugu adkaystaan saamaynta xoqidda ee walxaha badan sida silica, macdanta, galaaska, slag, dambaska duqsiga, dhagaxa nuuradda, dhuxusha, kookaha, quudinta, hadhuudhka, bacriminta, milixda iyo walxaha kale ee aadka u xoqidda.
Dahaarka u adkaysta xoqidda iyo xirashada ee ka yimaada Zhongpeng wuxuu ku habboon yahay warshado badan. Macaamiishu waxay u dhexeeyaan warshadaha budada ilaa warshadaha dhuxusha, korontada, macdanta iyo cuntada halkaas oo af-xidhka FGD loo oggolaaday in loo isticmaalo Shiinaha Electric Power Group. Dahaarka iska caabbinta xirashada ZPC waxaa lagu suuqgeeyaa Mareykanka, Kanada, Austrilia, Mexico, Koonfur Afrika, iwm. Waxay ku habboon yihiin qaybaha dahaarka ee u nugul xoqidda daran ee maaraynta walxaha dhirta iyo hawlgallada farsamaynta. Dahaarka SiC, taarikada iyo baloogyada ayaa waxtar u leh codsiyada sida tuubooyinka, shabagyada, xusullada, kala-soocidda, duufaannada, silos, bunkers, weelasha sibidhka iyo birta, tuubooyinka, impellers iyo agitators, daabyada taageeraha iyo dahaarka taageeraha, boolal gudbiye, gudbiye silsilad, isku-darka, pulpers; meel kasta oo xoqidda ay keento is-jiidjiidku ay dhibaato ku tahay.
Foornooyinka u adkaysta xoqidda si loo ilaaliyo xirashada, si loo daboolo dhibaatooyinka gaarka ah ee xoqidda, saameynta iyo daxalka ee macaamiisha. Isticmaalka dahaarka u adkaysta xirashada ZPC SiC ee qaybaha dhibaatada leh waxay ku dareysaa keydin weyn sababtoo ah cimrigooda dheer ee adeegga. Qiimaha qaybaha beddelka, waqtiga shaqada oo yaraada, nadiifinta warshadda iyo kharashka shaqada dayactirka ayaa dhammaantood si weyn hoos ugu dhacay. Kaydka la galay wuxuu bixin doonaa dahaarka iyo rakibidda waqti gaaban gudaheed.
Bushing-ka silica carbide waa nooc cusub oo ah walxo casri ah oo u adkaysta xirashada. Waxaa laga sameeyay budada silikoon carbide saafi ah, madow kaarboon heer sare ah oo saafi ah iyo walxo isku xidha, iyadoo la shubayo, la faarujinayo, la sifaynayo, iyo hababka ka saarista ciidda, oo laga sameeyay badeeco isku dhafan oo xirashada sare leh.
Waxaa hadda loo isticmaalaa sidii bushing qalabka macdanta, sida naxaasta, dahabka, macdanta birta, macdanta nikkel iyo kuwa kale ee biraha aan birta ahayn. Waxay door ka ciyaartaa iska caabinta xirashada sare, cimriga xirashadu waa in ka badan 10 jeer ka badan bushings birta caadiga ah iyo bushing alumina.
1. Adeegsiga bushing-ka warshadaha macdanta
Buuxinta macdanta, gaadiidka budada iyo dabada ayaa si xun u duugoobaya dhuumaha. Cimriga adeegga ee dhuumaha raritaanka budada macdanta ee la isticmaali jiray waagii hore waa wax ka yar hal sano, haddana dooro bushings silicon carbide ah ayaa kordhin kara cimriga adeegga in ka badan 10 jeer.
2. Maxaa loogu isticmaalaa warshadaha macdanta silsiladda silicon carbide?
Sababo la xiriira iska caabbinta xirashada tuubooyinka dhoobada ah, waxaa soo socda isbarbardhigga iska caabbinta xirashada tuubooyinka dhoobada ah iyo agabka kale.

5. Xidhiidhka bushing-ka ee Silicon carbide
(1) Marka tuubooyinka dabacsan loo isticmaalo in lagu xiro tuubooyinka rakibidda, dhererka gelinta labada daraf ee gacanta tuubada dabacsan waa in si siman loo hagaajiyaa. Farqiga ballaarinta waa inuu ku salaysnaadaa xaaladaha maxalliga ah ama shuruudaha waaxda naqshadeynta.
(2) Marka la isticmaalayo isku xirka flange-ka, wejiga flange-ku waa inuu la jaanqaadaa wejiga ugu dambeeya ee tuubada isku dhafan.
Shirkadda Shandong Zhongpeng Special Ceramics Co., Ltd waa mid ka mid ah xalalka ugu waaweyn ee walxaha cusub ee dhoobada carbide ee laga sameeyo Shiinaha. Dhoobada farsamada ee SiC: Adkaanshaha Moh waa 9 (adagaanshaha New Moh waa 13), oo leh iska caabin aad u fiican oo ka dhan ah nabaad-guurka iyo daxalka, xoqid aad u fiican - iska caabin iyo ka-hortagga oksaydhka. Nolosha adeegga ee badeecada SiC waa 4 ilaa 5 jeer ka dheer 92% walxaha alumina. MOR ee RBSiC waa 5 ilaa 7 jeer ka badan SNBSC, waxaa loo isticmaali karaa qaabab badan oo adag. Habka xigashada waa mid degdeg ah, gaarsiintu waa sidii la ballanqaaday tayadana waa mid aan la barbar dhigi karin. Had iyo jeer waxaan ku adkaysannaa inaan ku guuleysanno yoolalkeenna oo aan qalbiyadeenna dib ugu celinno bulshada.
