Xidho dhoobada u adkaysatadahaarka waxay bixiyaan saameyn aad u wanaagsan iyo ilaalin u adkeysiga nabarrada. Si gaar ah loo dhisay si loogu isticmaalo meel kasta oo xidhashada iyo naaxinta ay dhibaato ku tahay, dahaarka ZPC® waxay yareeyaan wakhtiga hoos u dhaca iyo dayactirka. Dahaarka dhoobada ah ee SiC aad ayey ugu adkaysanayaan waxyeelada abrasive ee agabka badan sida silica, ore, galaas, slag, ash fly, limestone, dhuxusha, kookaha, quudinta, hadhuudhka, bacriminta, milixda iyo agabka kale ee aadka u aadka u xoqa.
Abrasion u adkaysta oo xidho dahaarka adkaysiga u leh ee Zhongpeng ayaa ku habboon warshado badan. Macaamiishu waxay kala duwan yihiin warshadaha budada ilaa dhuxusha, korontada, macdanta iyo warshadaha cuntada halkaasoo FGD nozzles loo oggolaaday isticmaalka Kooxda Korontada ee Shiinaha. Dahaarka xidhashada iska caabbinta ZPC waxaa lagu suuq gayn Maraykanka oo dhan, Canada, Austrilia, Mexico, South Africa, iwm. Waxay ku fiican yihiin qaybaha dahaarka u nugul naaxinta daran ee wax ka qabashada alaabta dhirta iyo hawlgallada processing. Dahaarka SiC, taarikada iyo baloogyada ayaa wax ku ool u leh codsiyada sida tuubooyinka, tiirarka, xusullada, kala-soocida, duufaannada, silooska, baakadaha, barkadaha shubka iyo birta, maqaaradaha, mashiinnada iyo kiciyeyaasha, marawaxadaha iyo daboollada marawaxadaha, boolal-qaadayaasha, gaadiidleyda silsiladaha, qaswadayaasha, saafiyadaha; meel kasta oo ay naaxdu keento khilaafku waa dhibaato.
Tiirarka u adkaysta abrasion ee ilaalinta xidhashada, si ay ula kulmaan naaxinta gaarka ah ee macmiilka, saamaynta iyo dhibaatooyinka daxalka. Isticmaalka ZPC SiC waxay xidhaan dahaadh adkaysi u leh qaybaha dhibaatada leh waxay ku kordhisaa kaydad la taaban karo sababtoo ah noloshooda adeeg ee dheer. Qiimaha qaybaha beddelka, wakhtiga hoos u dhaca hawlaha, nadiifinta dhirta iyo kharashka shaqada dayactirka ayaa si weyn hoos ugu dhacay. Kaydinta la galay waxay bixin doontaa kharashka dahaarka iyo rakibidda waqti gaaban gudaheed.
Silicon carbide sic bushing waa nooc cusub oo teknoolojiyad sare ah oo u adkaysata xidhashada adduunka. Waxay ka samaysan tahay budada carbide silikoon nadiif ah oo nadiif ah, kaarboon madow oo nadiif ah oo heerkul sare leh iyo xidhidhayaal, iyadoo la shubayo, bannaynayo, sintayn, iyo geeddi-socod ciid-saarid, oo ka samaysan badeecad dhar xidhid sare leh.
Waxaa hadda loo isticmaalaa sida duurka ee qalabka macdanta, sida copper, dahab, birta birta, nikkel ore iyo kuwa kale ee biraha non-ferrous.It ciyaara doorka caabbinta xirashada sare, nolosha xirashada waa in ka badan 10 jeer ka caadiga ah. bushings birta ah iyo kaynta aluminium.
1.Codsiga sic baadiyaha ee warshadaha macdanta
Buuxinta miinada, gaadiidka budada ah ee xoogga leh iyo gaadiidka dabada ayaa si xun u gashanaya dhuumaha. Nolosha adeegga ee budada budada ah ee gudbinta dhuumaha loo isticmaalo waagii hore waa wax ka yar hal sano, oo hadda dooro duurka carbide silicon waxay kordhin kartaa nolosha adeegga in ka badan. 10 jeer
2.Waa maxay sababta dahaarka silikoon carbide si weyn loogu isticmaalo warshadaha macdanta?
Sababtoo ah iska caabin xirashada eetuubada dhoobadas, soo socota waa isbarbardhigga caabbinta xirashadatuubada dhoobadas iyo qalab kale.

(1) Marka tubooyinka dabacsan loo isticmaalo in lagu xidho tuubooyinka rakibaadda, dhererka gelinta labada daraf ee gacmo-gacmeedka tuubada dabacsan waa in si siman loo hagaajiyaa. Farqiga fidinta waa in lagu saleeyaa xaaladaha deegaanka ama shuruudaha waaxda naqshadeynta.
(2) Marka la isticmaalayo isku xirka flange, wejiga flange waa in lagu nadiifiyaa wejiga dhamaadka ee tuubada isku dhafan.
Shandong Zhongpeng Ceramics Co., Ltd waa mid ka mid ah xalalka alaabta cusub ee silikoon carbide ugu weyn ee Shiinaha. dhoobada farsamada ee SiC: Adkeeyga Moh waa 9 (Adayga cusub ee Moh waa 13), oo leh iska caabin aad u wanaagsan oo nabaadguurka iyo daxalka, nabaad-guurka aad u fiican - iska caabbinta iyo anti-oxidation. Nolosha adeegga sheyga SiC waa 4 ilaa 5 jeer in ka badan 92% walxo aluminium ah. MOR ee RBSiC waa 5 ilaa 7 jeer ka SNBSC, waxa loo isticmaali karaa qaabab aad u adag. Habka xigashada waa mid degdeg ah, gaarsiinta waa sidii balanta ahayd, tayaduna waa labaad ee midna. Had iyo jeer waxaan ku adkaysannaa inaan ka hortagno yoolalkayaga oo aan dib u soo celinno quluubtayada bulshada.
