PEEK (poly-ether-ether-ketone) bụ polymer pụrụ iche nke nwere otu njikọ ketone na njikọ ether abụọ na agbụ isi.
N'ihi nnukwu ọnụọgụ benzene mgbanaka mgbanaka, PEEK na-egosipụta njirimara zuru oke dị oke mma, dị ka oke nguzogide okpomọkụ dị elu, nguzogide corrosion, ezigbo akụrụngwa akụrụngwa, nguzogide mmetụta, mmanye onwe ya, ire ọkụ na ihe ndị ọzọ.
Taa, anyị na-ekwu maka uru PEEK dị n'ihe gbasara oke okpomọkụ na nguzogide corrosion.
1.PEEK nguzogide oke okpomọkụ
N'ime ụlọ ọrụ petrochemical, a na-ejikarị ihe PEEK eme ihe n'ihi oke okpomọkụ ya, yabụ kedu uru PEEK dị ma e jiri ya tụnyere plastik ndị ọzọ thermoplastic special engineering?
Fig 1. Ebe mgbaze na ogologo oge ojiji okpomọkụ eserese nke thermoplastic engineering plastik a na-ejikarị eme ihe
Site na Fig1., anyị nwere ike ịhụ na ebe mgbaze na okpomọkụ ọrụ ogologo oge nke PEEK dị elu karịa nke plastik anọ ndị ọzọ thermoplastic pụrụ iche.Ya mere, ihe PEEK nwere ike igosi ezigbo nguzogide okpomọkụ.
Enwere ike ịnwale arụmọrụ dị elu nke nguzogide okpomọkụ dị elu nke PEEK site na mbelata okpomọkụ dị elu na mkpakọ okpomọkụ dị elu.
Dị ka e gosiri na foto a:
Fig.2 PEEK5600G na PEEK5600CF30.
Ngwongwo na-ehulata oke okpomọkụ na oke mkpakọ okpomọkụ
Enwere ike ịhụ site na Fig.2 na, dị ka plastik niile, ihe eji arụ ọrụ ha na-ebelata nwayọọ nwayọọ na mmụba nke okpomọkụ.Agbanyeghị, n'ihi nguzogide oke okpomọkụ nke PEEK ya, ọ ka nwere ike idowe ihe dịka 70% nke arụmọrụ mbụ na 100C.
2. PEEK super corrosion eguzogide
N'ime mmepụta na ndụ n'ezie, ihe PEEK na-ejikwa nguzogide corrosion, dị ka PEEK capillaries maka ngwa nyocha, nkwonkwo PEEK na ihe ndị ọzọ.
Tab.1 Tebụl na-eguzogide corrosion nke ọtụtụ plastik injinia pụrụ iche
Enwere ike ịhụ site na Tab.1 na nguzogide corrosion nke PPS bụ otu ihe ahụ dị ka nke PEEK, ebe nkwụsị nke PPSU, PEI, PI dị njọ karịa nke PEEK.
Ngwaahịa PEEK nwere ezigbo nguzogide kemịkalụ.N'ime kemịkalụ a na-ahụkarị, ọ bụ naanị sulfuric acid nwere ike gbazee ma ọ bụ mebie ya, nguzogide corrosion ya dịkwa ka nke ígwè nickel.
