Mbiri yachisinthiko yamakampani a eptfe

Chisinthiko cha makampani a eptfe ndi nkhani yochititsa chidwi yomwe yakhala ikuchitika pakapita nthawi kuti ipange mafakitale okhala ndi ntchito zosintha.Mbiri ya epoxy imayamba mu 1884, pamene katswiri wa zamankhwala Alfred Einhorn anapanga gulu latsopano kuchokera ku ethylene ndi formaldehyde.Gululi limatchedwa "epoxide", lomwe pamapeto pake linadziwika kuti epoxy pophatikiza ndi polyol kapena esters.Ngakhale kuti mapangidwe oyambirirawa anali ndi ntchito zambiri zothandiza, kugwiritsidwa ntchito kwake kunakhalabe kochepa chifukwa cha kukwera mtengo kwake komanso kusowa kwa zipangizo zomwe zilipo.M'zaka za m'ma 1940 ofufuza angapo anayesetsa kukonza mapangidwe oyambirira a epoxy kuphatikizapo American Richard Condon yemwe adatulukira momwe angapangire kuti ikhale yolimba kwambiri pogwiritsa ntchito polyols yochokera ku mafuta a petroleum monga cyclohexane oxide ndi phenol novolak resin.Nthawi yomweyo asayansi aku Britain adayamba kuyesa njira zosiyanasiyana zochiritsira monga ma amines ndi ma acid zomwe zidapangitsa kuti pakhale chinthu chowongolera chomwe chitha kugwiritsidwa ntchito ngati plywood kuti chikhale champhamvu kuposa kale ndikutsegulira njira zamakono zopangira zida zamakono.Pa Nkhondo Yachiwiri Yadziko Lonse, ntchito zankhondo za epoxies zidawonjezeka kwambiri ndikupanga kufunika kwazinthu zabwinoko zomwe zimatsogolera ogulitsa kukhala ndi katundu wapadera monga kukana kutentha, kusinthasintha kwa kutentha, kukana kwamankhwala etc., kuwalola kuti akwaniritse zofunikira zomwe zimafunikira pakupanga magawo oyendetsa ndege.Kukula kwaukadaulo uku kudapitilira mpaka m'ma 1950s pomwe kupita patsogolo kudapangidwa munjira zonse zopangira utomoni wopangira utomoni limodzi ndi omwe amapangidwa molumikizana pakati pa mphira wachilengedwe & zosakaniza za mphira zophatikizika ndi zodzaza ngati asibesito kupanga zomwe tikudziwa masiku ano monga 'ma elastomer odzazidwa' kapena mphira zolimbitsa mapulasitiki (FRP).Pofika koyambirira kwa zaka za m'ma 1960 njira zosiyanasiyana zidakonzedwa bwino kwambiri kotero kuti njira zopangira zinthu zambiri zamafakitale zitha kukhazikitsidwa zomwe zimapangitsa kuti pakhale chitukuko chowonjezera pakuwonjezera mitundu ndi zowonjezera zina zomwe zimapangitsa kuti pakhale ma epoxies amakono osinthika omwe amagwiritsidwa ntchito m'mafakitale angapo kuyambira pakumanga & uinjiniya kudzera pakupanga magalimoto kumanja. mpaka posachedwapa ma semiconductor apakapaka ma semiconductor omwe amagwiritsidwa ntchito popanga zinthu zovuta zomwe zimafunikira luso lamphamvu la ufa pakati pa ena pamodzi ndi matekinoloje okutira a ceramic ophatikiza tinthu tating'ono ta diamondi zomwe zimalola opanga zida zodulira kuti azitha kuchita bwino kwambiri zomwe sizinamveke zaka makumi awiri izi zisanachitike.Mndandanda wanthawiyi ukuwonetsa momwe tafika kuyambira pomwe zidapangidwa koyamba mu 1884 mpaka kuchulukirachulukira komwe kukukulirakulira motsogozedwa ndi kafukufuku yemwe akupitilirabe kupitilira malire omwe amayembekeza panthawi yomwe Alfred Einhorn adatsegulira moyo wake zomwe sizinali zoyembekezeka kutha motero kutha kwaulendo wodabwitsa wachisinthiko wolumikizana ndi masiku ano. kupita patsogolo kopindulitsa kwambiri mibadwo yamtsogolo padziko lonse lapansi.
