1. Cadaadiska caabbinta
FGD nozzlesKu shaqee jawiga aadka u sareysa oo ay ku jiraan Sulfur Oxelkii, Chlorides, iyo kiimikooyin kale oo dagaal badan. Silicon Carbide (Sic) dhoobada ayaa muujinaya iska caabbinta ka-reeban ee wax ka yar 0.1% khasaaraha ballaaran ee Ph 1-14 xalalka (halkii ASTM C863). Marka la barbar dhigo bir bir-qaadka ah
2. Deganaansho heerkul ah
Heerkulka ku shaqeeya Nidaamyada Burue-ga ee Xirmooyinka Gasleys-ka ee Gaaska ah sida caadiga ah waxay udhacdaa 60-80 ° C oo leh dheecaan ka badan 120 ° C. CIC Rouxic wuxuu hayaa boqolkiiba 85% xoog-heerkulka-1000 ° C, oo ka mid ah qaxwada alumina (luminta 50% xoogga 1000 ° C) iyo stors kuleylka u adkaysta. Tallaabadeeda kuleylka (120 w / m · k) wuxuu awood u siinayaa ku-meel-gaarka ah ee kululaynta ku habboon, ka hortagga kuleylka kuleylka kuleylka.
3. Xiro iska caabbinta
Iyada oo ay ku sii adkaato ee 28 GPA iyo CPA iyo jawiga adag ee 4.6 MPA · / m¹ / ², SIC ayaa muujinaya iska caabbinta nabaad-guurka ee ka hortagga ash ee duulista (Mohs 5-7). Imtixaanada garoonka ayaa muujinaya in sicsines "ay xirto 2,000 saacadood ka dib 20,000 saacadood oo adeeg ah, marka la barbar dhigo 30-40% waxay xirtaan alumina nozzles iyo guuldarro dhameystiran oo birta lagu dahaadey oo ah 8,000 saacadood gudahood.
4. Astaamaha qulqulka
Dusha sare ee aan qoyn oo kacsan ee sicirka (xagal la xidhiidha> 100 °) waxay awood u siineysaa kala-guurka saxda ah ee qiimayaasha spurry ee leh qiimayaasha cv <5%. Dusha sare ee ultra-styra (Ra 0.2-0.4M) waxay yareysaa hoos udhaca cadaadiska ee 15-20% marka la barbar dhigo iswada buluuga ah, inta ay sii wadan yihiin isku-darka dheecaanka xasilloon (± 1%) qalliinka muddada-dheer.
5. Fududeynta dayactirka
Xirmooyinka kiimikada ee SIC waxay u oggolaaneysaa habab nadiif ah oo nadiifin ah oo ay ka mid yihiin:
- Jet-ka sare ee cadaadiska sare (ilaa 250 bar)
- Nadiifinta ultrasonic ee xalka alkaline
- Steam sterlitization-ka 150 ° C
Halis la'aan oo aan sabab lahayn xaalufinta dusha sare ee polymer-polymer-saran ama qalooca qafiif ah.
6. Dhaqaalaha Nolosha
In kasta oo kharashaadka ugu horreeya ee Sic Foozzles ay yihiin 2-3 × ka sarreysa heerka 316l bir bir ah, nolosha adeegga ee 8-10 sano (Vs 2-3 sano ee loogu talagalay biraha) waxay yareysaa bedelka soo noqnoqda 70%. Wadarta Qiimaha Lahaanshaha Show 40-60% keydinta ka badan 10 sano gudahood, oo leh eber Downsit-ka ee dayactirka gudaha-ku dayactirka.
7. Imaatinka deegaanka
Sic wuxuu muujiyaa waxqabadka aan tooska aheyn ee xaaladaha ba'an:
- Iska caabbinta milixda lagu buufiyo
- Howlgallada aashitada ee sawadda: Waxay ka hortagtaa 160 ° C H2SO4 Vapors
- Cadaadiska naxdinta leh
8. Guryaha ka hortagga is-ka-hortagga
Qaab-dhismeedka atomiga ah ee SIC-ga ee SIC waxay abuurtaa dusha sare ee falcelinta oo leh heerarka isgoysyada 80% ka hooseeya waxyaabaha kale ee birta ah. Daraasadihii Curtstaronographic waxay muujinayaan in canugga caclite iyo Gypsum-ka ay sameeyaan dammaanad jilicsan
Gunaanad Farsamo
Silicon Carbide Chomice Clobide Coos ayaa ah doorashada ugu habboon ee loo yaqaan 'Expimal Exectal' ee FGD Nzzles iyada oo loo marayo qiimeynta waxqabadka ee dhameystiran:
- 10 × nabar dheeri ah oo ka dheer sidii wax kale oo loo yaqaan 'Metallic'
- 92% dhimista dayactirka aan qorshaysnayn
- 35% hagaajinta si hufnaanta sifeynta ee sifeynta ah iyada oo loo marayo qaabab buufin oo joogto ah
- U hogaansanaanta EPA 40 CFR-ka ee Qiimaha Qiimaha Qeybta 63
Iyada oo la adeegsanayo farsamooyinka wax soo saarka sida sanduuqa dareeraha ah iyo daboolka cvd, nozzles-ka soo socota ayaa ah inay ka gaaraan dusha hoosaad-hoosaadka iyo qaababka murugada leh ee aan caadiga ahayn ee dhoobada aan la qiyaasi karin. Meelahaan tikniyoolajiyadda thiscicon-ka silicon Carbide sida aaladda doorashada ee nidaamyada nadiifinta gaaska ee soo socda.
