- Uru nke mmeghachi omume BONDED SILICON CARBIDE
Ngwaahịa Silicon Carbide Reaction Bonded (RBSC, ma ọ bụ SiSiC) na-enye oke ike ike/abrasion nkwụsi ike na nkwụsi ike kemịkalụ pụtara ìhè na gburugburu ebe ike ike. Silicon Carbide bụ ihe sịntetịt nke na-egosipụta njirimara arụmọrụ dị elu gụnyere:
lNguzogide kemịkalụ mara mma.
Ike nke RBSC fọrọ nke nta ka ọ bụrụ 50% karịa nke ọtụtụ nitride bonded silicon carbides. RBSC bụ ihe magburu onwe corrosion eguzogide na antioxidation seramiiki .. Ọ nwere ike kpụrụ n'ime a dịgasị iche iche nke desulpurization nozzle (FGD) .
lỌkachamara iyi na mmetụta mgbochi.
Ọ bụ nnukwu teknụzụ seramiiki na-eguzogide abrasion. RBSiC nwere ike siri ike na-abịaru nso nke diamond. Ezubere maka ojiji na ngwa maka nnukwu ụdị ebe akara nrịbama nke silicon carbide na-egosipụta ncha ma ọ bụ mmebi site na mmetụta nke nnukwu irighiri ihe. Na-eguzogide kpọmkwem mgbochi nke ụmụ irighiri ihe ọkụ yana mmetụta na mmịfe abrasion nke ihe siri ike nwere slurries. Enwere ike ịmepụta ya ka ọ bụrụ ụdị dị iche iche, gụnyere cone na ụdị aka aka, yana ihe mgbagwoju anya dị mgbagwoju anya emebere maka akụrụngwa na-etinye aka na nhazi nke akụrụngwa.
lMagburu onwe thermal ujo eguzogide.
Ihe mejupụtara silicon carbide mmeghachi omume na-enye nguzogide ujo dị egwu mana n'adịghị ka seramiki ọdịnala, ha na-ejikọta njupụta dị ala na ike ọrụ dị elu.
lIke dị elu (na-enweta ike na okpomọkụ).
Silicon carbide reaction bonded na-ejigide ọtụtụ ike ọrụ ya na okpomọkụ dị elu ma gosipụta ọkwa dị ala nke na-akpụ akpụ, na-eme ka ọ bụrụ nhọrọ mbụ maka ngwa ibu ibu na nso 1300ºC ruo 1650ºC (2400ºC ruo 3000ºF).
