I-silicon carbide ceramic lined wear-resistant pipe kunye ne-hydrocyclone kwizityalo zamandla

IiNkqubo zeMibhobho yeCeramic yeSilicon Carbide: Ukubuyisela iziseko zophuhliso lweziko lombane

Izibonelelo zokuvelisa umbane zijongene nemingeni enzima yokusebenza, eneenkqubo zombhobho ezihlala zihleli:

- Ukuqhutywa kwebhayisekile eshushu (100–650°C)

- Izantya zamasuntswana abrasive angaphezu kwama-30 m/s

- iinguqu ze-pH ukusuka kwi-2-12 kwi-flue gas scrubbers

- Ukuguquguquka koxinzelelo lwebhayisekile (0–6 MPa)

Imibhobho yentsimbi yesiNtu kunye neyepolymer ihlala isilela phantsi kwezi meko, yenze imibhobho ye-silicon carbide (SiC) i-ceramic ekwaziyo ukunxitywa ibe sisisombululo esiyinjineli kwizityalo zanamhlanje zamandla.

Material Science Breakthrough

Imibhobho ye-ceramic ye-SiC idibanisa iipropati ezizodwa ezibalulekileyo kwizicelo zecandelo lamandla:

-Vickers Hardness 28 GPa (4× nzima kunetungsten carbide)

-Inqanaba lokunxiba <0.1 mm³/N·m (ASTM G65)

-I-Thermal Conductivity 120 W/m·K (iphezulu kunentsimbi engatyiwayo)

-Ukunganyanzeli kweMichiza (ixhathisa i-98% ye-H₂SO₄ kwi-300 ° C)

Izinto eziluncedo zokuSebenza kwiiNkqubo eziBalulekileyo

1. Ukuphatha amalahle kunye nokuThuthwa kothuthu

- Ukumelana ne-5-7 mm / ngonyaka ukunxitywa kwe-erosive ukusuka kwi-60% ye-slurry yomxholo oqinileyo

- Gcina i-<5% yokunciphisa ukuhamba kweeyure ze-10,000 zokusebenza

2. Ukutshatyalaliswa kweGesi yeFlue (FGD)

- Ukusebenza ukumelana ne-pH kwiisekethe ze-limestone slurry

- Ukuphelisa i-chloride-induced pitting corrosion

3. UkuHambisa uthuthu

- 0.08 μm uburhabaxa bomphezulu bunciphisa ukunamathela kwamasuntswana

-Bamba umthamo we-50 tph kwii-angles zokuthambekela ezingama-35 °

INguqu yezoQoqosho

Abaqhubi bezityalo banika ingxelo yeenzuzo ezinokulinganiswa:

- 70% yokunciphisa ukutshintshwa kwemibhobho engacetywanga

- 55% iindleko zokusebenza zokulungisa ezisezantsi

- I-18% iphucule ukusebenza kakuhle kwe-thermal kwimijikelo yomphunga

- I-40% yenkqubo eyandisiweyo yokuphila ngokuchasene ne-alloy alternatives

Ukufakela kunye nokuSebenza okuGuquguqukayo

- Amacandelo emodyuli ayi-1–6 m anoqhagamshelo olunemisonto/nemisonto

- 60% yokunciphisa ubunzima vs. ukulingana kwentsimbi (3.2 g/cm³ density)

- I-Retrofittable kwinkxaso yombhobho esele ikhona kunye nee-hangers

- Iyahambelana neenkqubo zokubeka iliso ezihlakaniphile zokuqikelela ukunxiba

Izinto ezintsha ezigxile kwikamva

Izisombululo zemibhobho yeSiC yesizukulwana esilandelayo ziyadibanisa:

-I-gradient porosity yokunciphisa uxinzelelo lwe-thermal

-Iintlobo ngeentlobo ze-electrostatic precipitation

- Ingxubevange ye-ceramic-elastomer ye-hybrid ye-vibration damping

- Ukuzicoca umphezulu we-nano-textures

Ukusuka kwizityalo ezibaselwe ngamalahle ukuya kwi-inkunkuma-to-energy izibonelelo, i-silicon carbide imibhobho ye-ceramic ichaza ngokutsha ukuthembeka kwiziseko zombane. Inhlanganisela yabo ekhethekileyo yokuqina komatshini, ukunyamezela kwe-thermal, kunye nokuzinza kweekhemikhali kuqinisekisa ukusebenza ngokuqhubekayo phantsi kweemeko ezinzima - ukuguqula iishedyuli zokulungisa ukusuka ekulungiseni okusebenzayo ukuya kuphuculo olucwangcisiweyo, oluneendleko ezifanelekileyo.

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubunzima be-Moh yi-9 (ubunzima be-Moh entsha yi-13), kunye nokumelana okugqwesileyo kukhukuliseko kunye ne-corrosion, 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.
