Myiri arụmọrụ yana ntụnyere n'etiti PEI na PEEK

Polyetherimide, nke a na-akpọ PEI na Bekee, Polyetherimide, nwere ọdịdị amber, bụ ụdị amorphous thermoplastic special engineering plastic nke na-ewebata njikọ ether na-agbanwe agbanwe (- Rmae Omi R -) n'ime ụmụ irighiri ogologo polyimide siri ike.

Ọdịdị nke PEI

Dị ka ụdị thermoplastic polyimide, PEI nwere ike imeziwanye thermoplasticity na-adịghị mma na nhazi siri ike nke polyimide site na iwebata njikọ ether (- Rmurmurr R -) n'ime agbụ polymer mgbe ị na-ejigide usoro mgbanaka nke polyimide.

Njirimara nke PEI

Uru:

Ike tensile dị elu, karịa 110MPa.

Ike mgbada dị elu, karịa 150MPa.

Ikike ibu nke thermo-mechanical mara mma, okpomọkụ nrụrụ ọkụ karịrị ma ọ bụ nhata 200 ℃.

Ezi nguzogide na-akpụ akpụ na ike ọgwụgwụ.

Ezigbo ọkụ retardancy na obere anwụrụ ọkụ.

Ezigbo dielectric na ihe mkpuchi.

Nkwụsi ike akụkụ dị oke mma, ọnụọgụ dị ala nke mgbasawanye thermal.

Nnukwu okpomọkụ na-eguzogide, nwere ike iji na 170 ℃ ruo ogologo oge.

Ọ nwere ike gafere microwaves.

Ihe ọghọm:

Nwere BPA (bisphenol A), nke na-amachi ngwa ya na ngwaahịa metụtara ụmụaka.

Mmetụta mmetụta uche.

Nguzogide Alkali bụ n'ozuzu, karịsịa n'okpuru ọnọdụ okpomọkụ.

PEEK

PEEK sayensị aha polyether ether ketone bụ ụdị polymer nke nwere otu njikọ ketone na njikọ ether abụọ n'ime usoro agbụ isi. Ọ bụ ihe polymer pụrụ iche. PEEK nwere ọdịdị beige, nhazi dị mma, nkwụsị na-eyi nguzogide, ezigbo nguzogide na-akpụ akpụ, ezigbo nguzogide kemịkalụ, ezigbo nguzogide hydrolysis na uzuoku na-ekpo ọkụ, radieshon dị elu, okpomọkụ dị elu nke nrụrụ okpomọkụ na ezigbo ọkụ ọkụ n'ime.

Ebu ụzọ jiri PEEK mee ihe n'ọhịa nke ikuku iji dochie aluminum, titanium na ihe ọla ndị ọzọ iji mee akụkụ nke ime na mpụga nke ụgbọ elu. N'ihi na PEEK nwere ọmarịcha akụrụngwa zuru oke, ọ nwere ike dochie ihe ọdịnala dịka ọla na seramiki n'ọtụtụ mpaghara pụrụ iche. Nguzogide okpomọkụ ya dị elu, mmanu mmanu onwe ya, nguzogide ike ọgwụgwụ na ike ọgwụgwụ na-eme ka ọ bụrụ otu n'ime plastik injinia kachasị ewu ewu.

Dị ka ihe eji eme ihe na-ekpo ọkụ na-ekpo ọkụ, njirimara nke PEI yiri nke PEEK, ma ọ bụ ọbụna ngbanwe nke PEEK. Ka anyị leba anya n'ihe dị iche n'etiti ha abụọ.

E jiri ya tụnyere PEEK, arụmọrụ zuru oke nke PEI na-adọrọ mmasị karị, na nnukwu uru ya bụ ọnụ ahịa, nke bụkwa isi ihe kpatara na-ahọrọ ụfọdụ ihe eji eme ụgbọ elu site na ihe mejupụtara PEI. Ọnụ ego zuru oke nke akụkụ ya dị ala karịa nke ígwè, ihe nrụpụta thermosetting na PEEK composites. Ekwesiri iburu n'uche na n'agbanyeghi na oru ugwo nke PEI di oke elu, nguzogide okpomọkụ ya adighi oke elu.

Na ihe mgbaze chlorinated, mgbawa nrụgide na-apụta n'ụzọ dị mfe, na iguzogide ihe mgbaze organic adịghị mma dị ka nke semi-crystalline polymer PEEK. Na nhazi, ọ bụrụgodị na PEI nwere nhazi nke plastik thermoplastic engineering omenala, ọ chọrọ okpomọkụ na-agbaze dị elu.
