Silicon carbide seramiiki lined wear-eguzogide ọkpọkọ
Silicon carbide ọkpọkọ na-eguzogide ọgwụ bụ ọkpọkọ emebere nke silicon carbide ma nwee ngwa sara mbara n'ọtụtụ mpaghara. Isi asọmpi ya bụ nke a:
(1) Ngbanwe Ndụ
Mgbe ị na-ebufe mgbasa ozi abrasive dị ka slurry na coal ash, ndụ ndụ dị okpukpu 10 karịa nke ọla, na-ebelata ngbanwe ugboro ugboro na mfu oge.
(2) Ọnọdụ ọrụ dị oke egwu bụ ụwa niile
Arụ ọrụ kwụsiri ike site na -50 ℃ ruo 1600 ℃, yana nguzogide ujo iji gbochie mgbawa, dabara adaba maka ọnọdụ okpomọkụ dị elu dị ka metallurgy na ụlọ ọrụ kemịkalụ.
(3) Ọtụtụ ojiji nke otu ihe
N'otu oge dozie nsogbu anọ bụ isi nke iyi, corrosion, oke okpomọkụ, na mgbochi mgbawa.
(4) Dị fechaa na nchekwa ike
Nhazi dị arọ na-ebelata ụgwọ njem na nrụnye, yana ọnụ ọgụgụ esemokwu dị ala na-ebelata ike ọkụ ọkụ.
Uru na-etipịa ọkpọkọ silicon carbide tụnyere ihe ọdịnala:
| Akụkụ arụmọrụ | Silicon carbide pipeline | Ọkpụkpọ ígwè/plastic |
| Yiri nguzogide | Isi ike 2800HV (ugboro ise nke ígwè), ogologo ndụ 10 ugboro karịa nke pipeline na-abụghị ọla. | Metal na-adịkarị mfe iyi na ịdọka, ebe plastik nwere ike siri ike (PE <1 HV) |
| Okpomọkụ dị elu iguzogide | Na-eguzogide oke okpomọkụ nke 1600 ℃ na thermal ujo (ọnụọgụ nke thermal mgbasa 4 × 10 ⁻⁶ / ℃) | Igwe anaghị agba nchara dị mfe na oxidation na oke okpomọkụ, ebe plastik nwere nguzogide okpomọkụ nke na-erughị 80 ℃. |
| Nguzogide corrosion | Na-eguzogide acids siri ike (sulfuric acid gbadoro ụkwụ), ntọala siri ike, na corrosion metal a wụrụ awụ. | Ahụmahụ igwe anaghị agba nchara na-enweta corrosion mgbe ekpughere ya na ion chloride, ebe plastik nwere oke mgbochi kemịkalụ |
| Dị fechaa | Njupụta nke 3.0 ~ 3.14 g/cm ³ (60% dị ọkụ karịa ígwè) | Ọkpụkpụ ígwè dị oke ibu ma nwee ọnụ ahịa nrụnye dị elu |
| Mgbasawanye arụmọrụ | Anti static ( conductivity adịghị ike), ọkwa semiconductor ịdị ọcha | Ọla na-achọ ọgwụgwọ ọzọ maka mgbochi mgbawa, ebe plastik na-enwekarị mmetọ |
Na nkenke, ọ fọrọ nke nta ka ọ bụrụ na ọ dịghị ihe ngwọta ọzọ maka silicon carbide pipeline mgbe ị na-ebufe mgbasa ozi na-emebi emebi na nke na-eguzogide ọgwụ dị ka acidic slurries na nnukwu okpomọkụ flue gas ash.
Ọ bụrụ na ị nwere ajụjụ ọ bụla, biko nweere onwe gị ịkpọtụrụ anyị n'oge ọ bụla.
Shandong Zhongpeng Special Ceramics Co., Ltd bụ otu n'ime nnukwu silicon carbide seramiiki ihe ngwọta ọhụrụ na China. SiC technical ceramic: Moh's hardness is 9 (New Moh's hardness is 13), na ezigbo nguzogide mbuze na corrosion, ọmarịcha abrasion - nguzogide na mgbochi oxidation. Ndụ ọrụ ngwaahịa SiC bụ 4 ruo 5 ugboro ogologo karịa 92% alumina ihe onwunwe. MOR nke RBSiC bụ 5 ruo 7 ugboro karịa nke SNBSC, enwere ike iji ya mee ihe maka ụdị mgbagwoju anya. Usoro nhota dị ngwa ngwa, nnyefe dị ka e kwere ná nkwa na àgwà bụ nke abụọ na ọ dịghị. Anyị na-anọgidesi ike mgbe niile n'ịgba ebumnobi anyị aka ma na-enyeghachi obi anyị azụ n'obodo.
