PEEK (poly-ether-ether-ketone) polymer ne na musamman wanda ya ƙunshi haɗin ketone ɗaya da ether bond biyu a cikin babban sarkar.
Saboda girman girman tsarin zobe na benzene, PEEK yana nuna kyawawan kaddarorin da suka dace, irin su kyakkyawan juriya na zafin jiki, juriya na lalata, kyawawan kaddarorin inji, juriya mai tasiri, lubrication kai, ƙin wuta da sauransu.
A yau, muna magana ne game da fa'idodin PEEK dangane da juriya mai zafi da juriya na lalata.
1.PEEK super high zafin jiki juriya
A cikin masana'antar petrochemical, ana amfani da kayan PEEK galibi saboda tsananin zafinsa, don haka menene fa'idodin PEEK idan aka kwatanta da sauran robobin injiniya na musamman na thermoplastic?
Hoto 1. Matsayin narkewa da zanen zafin amfani na dogon lokaci na robobin injiniyan thermoplastic da aka saba amfani da su
Daga Fig1., zamu iya ganin cewa ma'aunin narkewa da zafin sabis na dogon lokaci na PEEK sun fi na sauran robobin injiniya na musamman na thermoplastic.Sabili da haka, kayan PEEK na iya nuna kyakkyawan juriya na zafi.
Za'a iya gwada takamaiman aikin babban juriya na zafin jiki na PEEK ta hanyar lanƙwasawa mai zafi da matsanancin zafin jiki.
Kamar yadda aka nuna a cikin wannan adadi:
Hoto.2 PEEK5600G da PEEK5600CF30.
Babban zafin jiki lankwasawa dukiya da high zazzabi matsawa kwana
Ana iya gani daga Fig.2 cewa, kamar duk robobi, kayan aikin injin su suna raguwa sannu a hankali tare da karuwar zafin jiki.Koyaya, saboda kyakkyawan juriya na zafin jiki na PEEK, har yanzu yana iya kiyaye kusan 70% na ainihin aikin a 100C.
2. PEEK super lalata juriya
A cikin ainihin samarwa da rayuwa, kayan PEEK kuma suna amfani da juriya na lalata, kamar PEEK capillaries don kayan aikin nazari, haɗin gwiwar PEEK da sauransu.
Tab.1 Teburan juriya na lalata na robobin injiniya na musamman da yawa
Ana iya gani daga Tab.1 cewa juriya na lalata na PPS daidai yake da na PEEK, yayin da juriya na PPSU, PEI, PI ya fi na PEEK muni.
Kayayyakin PEEK suna da kyakkyawan juriya na sinadarai.A cikin sinadarai na gama-gari, sulfuric acid ne kawai zai iya narke ko lalata shi, kuma juriyar lalatarsa yayi kama da na karfen nickel.
