Menene PEEK?

Ketone na Polyether ether (Poly-ether-ether-ketone, PEEK a takaice) wani nau'in kayan polymer ne na musamman wanda ya ƙunshi raka'a masu maimaitawa waɗanda ke ɗauke da haɗin ether guda biyu da haɗin ketone ɗaya a cikin babban tsarin sarkar. Jerin kayan polyether ketone ne. Yana da halaye na yanayin kristal mai-ƙulli, juriya ga zafin jiki mai yawa, juriya ga lalata sinadarai da sauransu.

Halayen PEEK

Polyether ether ketone (PEEK) a halin yanzu shine kawai nau'in kayan polyaryl ether ketone (PAEK) da za a iya samar da su da yawa. PEEK, a matsayin filastik na musamman na injiniya, yana da kyawawan halaye masu kyau.

Amfani da PEEK

Resin Polyether ether ketone (PEEK) wani nau'in kyakkyawan aiki ne na filastik na injiniya na musamman, fa'idodi da yawa idan aka kwatanta da sauran robobi na injiniya na musamman, juriya mai zafi, kyakkyawan aikin injiniya, man shafawa kai, juriyar lalata sinadarai, hana harshen wuta, juriyar cirewa, juriyar radiation, kwanciyar hankali na rufi, juriyar hydrolysis da sauƙin sarrafawa, da sauransu, ana amfani da su sosai a fannin likitanci.

Resin PEEK zai iya jure har zuwa zagaye 3000 na autoclaving a zafin jiki na 134 ° C, wanda hakan ya sa ya dace da ƙera kayan aikin tiyata da na hakori masu tsafta waɗanda ke buƙatar amfani akai-akai. PEEK ba wai kawai yana da fa'idodin nauyi mai sauƙi ba, mara guba da juriya ga tsatsa, har ma yana da halayen modulus na roba na ƙashin cortical na ɗan adam, wanda za'a iya haɗa shi da jiki ta hanyar halitta. Saboda haka, amfani da resin PEEK maimakon ƙarfe don ƙera kwarangwal na ɗan adam wani muhimmin aiki ne a fannin likitanci.

An fara amfani da PEEK a asibitin a shekarar 1999. Tun daga lokacin, sama da miliyan biyar ne suka fara amfani da shi.Kayayyakin PEEKan dasa su a cikin mutane, wanda hakan ya sanya su zama mizani na zinare a cikin haɗin kashin baya. A cikin 'yan shekarun nan, an yaba wa PEEK a matsayin "abin da ya dace don ƙarni na gaba na samfuran likitanci da za a iya dasawa".

Tarihin PEEK

Lokacin farko na ƙumburi (1978-1992):

PEEK wani nau'in filastik ne na musamman na injiniya mai inganci wanda ICI ta ƙirƙiro a shekarar 1978. ICI ta nemi haƙƙin mallaka kuma ta mayar da shi masana'antu, tare da ƙarfin samarwa na tan 1000 a kowace shekara, wanda galibi ana amfani da shi a masana'antar tsaro.

Ci gaban Monopoly da Rushewar Monopoly (1993-2004):

Victrex ya sami kasuwancin PEEK daga ICI, wanda ya nuna yanayin ci gaban kashin kansa, kuma ya ci gaba da faɗaɗa girman samarwa. A shekara ta 2003, ƙarfin samarwa na shekara-shekara ya karu zuwa tan 2800. Daga baya, DuPont, BASF, Mitsui Tosei Chemical Company na Japan, da Telep na Amurka sun haɓaka irin waɗannan kayayyaki a jere. PEEK ya faɗaɗa daga aikace-aikacen soja na farko zuwa aikace-aikacen masana'antu da na likitanci.

Na dogon lokaci Kwamitin Gudanarwa na Paris ya sanya PEEK a matsayin kayan aiki masu mahimmanci don toshewa da takunkumin da China ta sanya wa ƙasar. Domin biyan buƙatun tsaron ƙasa da ci gaban fasaha mai zurfi, jihar ta haɗa shi cikin manyan ayyukan bincike na kimiyya da fasaha na ƙasa daga Tsarin shekaru biyar na bakwai zuwa Tsarin shekaru biyar na goma da Tsarin bincike na 863. A ƙarƙashin goyon bayan manufofin China, ƙungiyar Farfesa Wu Zhongwen ta Jami'ar Jilin ta haɓaka fasahar mallakar fasaha ta PEEK tare da haƙƙin mallakar fasaha mai zaman kanta kuma ta kafa Kamfanin Jida High-tech Materials Co., LTD., wanda aka sanya shi cikin samarwa.

Matakin Ci Gaba Mai Girma (2005-yanzu):

A shekarar 2005, Evonik ta sayi kasuwancin The PEEK na Garda na Indiya, yayin da Solvay ta sayi kasuwancin PEEK. A shekarar 2009, kamfanin Jinfa Technology Co., LTD. na kasar Sin, Panjin Zhongrun Special Plastic Co., Ltd. da sauran kamfanoni suka shiga wannan fanni, kuma PEEK ta shiga matakin ci gaba mai cike da abubuwa. Bugu da kari, gyaran fasahar hada-hadar PEEK da sarrafa kayayyaki yana ci gaba da bunkasa a hankali, kuma fannin aikace-aikacen ma yana fadada. Saboda yawan masana'antun da suka kware a samar da PEEK a duniya, matakin gasar kasuwa zai kara zafi. A halin yanzu, Wiggs, Solvay da Evonik su ne manyan masana'antun PEEK guda uku a duniya.
