Menene PEEK?
Polyether ether ketone(PEEK) kayan kamshi na polymer ne na thermoplastic. Wani nau'i ne na filastik injiniya na musamman tare da kyakkyawan aiki, musamman yana nuna ƙarfin juriya na zafi, juriya da kwanciyar hankali. Ana amfani da shi sosai a sararin samaniya, soja, mota, likitanci da sauran fannoni.
Babban aikin PEEK
PEEK yana da ƙarfin injina mai ƙarfi, juriya mai zafi, juriya mai tasiri, ƙarancin wuta, juriya acid da alkali, juriya na hydrolysis, juriya abrasion, juriya juriya, juriya na radiation da kyawawan kayan lantarki.
Shi ne mafi girman darajar juriya na zafi a cikin robobin injiniya na musamman.
Zafin sabis na dogon lokaci zai iya zama daga -100 ℃ zuwa 260 ℃.
PEEK roba albarkatun albarkatun suna da ingantattun halayen kwanciyar hankali. Yanayin da ke da babban zafin jiki da canje-canjen zafi yana da ɗan tasiri akan girman sassan PEEK, kuma ƙimar ƙwanƙwasa alluran PEEK kaɗan ne, wanda ke sa daidaiton girman sassan PEEK ya fi na manyan robobi, wanda zai iya biyan buƙatun daidaito mai girma a ƙarƙashin yanayin aiki.
PEEK yana da shahararren zafi - halayen hydrolysis mai jurewa.
A cikin yanayin zafi mai zafi da zafi mai zafi sha ruwa yana da ƙasa sosai, kama da nailan da sauran robobi saboda shayar da ruwa da girman canje-canje a bayyane.
PEEK yana da kyakkyawan ƙarfi da juriya na gajiya, kwatankwacin alloys, kuma ana iya amfani da shi na dogon lokaci a cikin buƙatun wuraren aiki. Don maye gurbin karfe, aluminum, jan karfe, titanium, ptFE da sauran kayan aiki masu mahimmanci, inganta aikin injin a lokaci guda yana rage farashin.
PEEK yana da tsaro mai kyau. Sakamakon gwajin UL na kayan ya nuna cewa PEEK's retardation index index shine Grade V-0, wanda shine mafi kyawun darajar jinkirin harshen. Konewar PEEK (watau adadin hayaki da ake samarwa yayin ci gaba da konewa) shine mafi ƙanƙanta na kowane filastik.
Rashin iyawar PEEK (yawan iskar gas da ake samarwa lokacin da ya lalace a babban zafin jiki) shima yayi ƙasa.
Tarihin PEEK
PEEK shine kayan da ke saman dala na filastik, kuma ƙananan kamfanoni a duniya sun mallaki tsarin polymerization.
ICI ta haɓaka PEEK a cikin 1970s. Saboda fitattun kayan aikin injiniya da kayan sarrafa shi, ya zama ɗaya daga cikin fitattun robobin injiniya na musamman.
Fasahar PEEK ta kasar Sin ta fara ne a shekarun 1980. Bayan shekaru na bincike mai zurfi, Jami'ar Jilin ta haɓaka tsarin haɗin gwiwar resin PEEK tare da haƙƙin mallaka na fasaha masu zaman kansu. Ba wai kawai aikin samfurin ya kai matakin PEEK na waje ba, har ma da albarkatun kasa da kayan aikin duk sun dogara ne a kasar Sin, tare da rage farashin samar da inganci yadda ya kamata.
A halin yanzu, masana'antar PEEK ta kasar Sin ta balaga sosai, tana da inganci da kayayyakin da ake samarwa a kasashen waje, kuma farashin ya yi kasa sosai fiye da kasuwannin duniya. Abin da ake buƙatar haɓaka shine wadatar PEEK iri-iri.
Victrex wani reshe ne na ICI na Biritaniya har sai da aka fitar da shi.
Ya zama farkon masana'antar PEEK a duniya.
