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 zosinthika.Mbiri ya epoxy imayamba mu 1884, pamene katswiri wa zamagetsi 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 kwaukadaulowu kudapitilira mpaka zaka za m'ma 1950 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 ngati 'ma elastomer odzazidwa' kapena mapulasitiki olimba (FRP). Pofika koyambirira kwa zaka za m'ma 1960 njira zosiyanasiyana zidayeretsedwa kwambiri kotero kuti makina opanga zinthu zambiri amatha kukhazikitsidwa ndikupangitsa kuti pakhale kusintha kwamitundu ndi zina zomwe zimapangitsa kuti pakhale ma epoxies amakono osinthika omwe amagwiritsidwa ntchito m'mafakitale angapo kuyambira pakumanga & uinjiniya kudzera pamapangidwe amagalimoto mpaka posachedwapa ma semiconductor ma phukusi opangira mayankho omwe amagwiritsidwa ntchito popanga zitsulo zopangira zinthu zina zomwe zimafunikira zitsulo. matekinoloje okhudza fumbi la diamondi omwe amalola opanga zida zodulira kuti azitha kuchita bwino kwambiri zomwe sizinamveke zaka makumi awiri izi zisanachitike. Mndandanda wanthawiyi ukuwonetsa momwe takhalira kuyambira pomwe zidapangidwa koyamba mu 1884 zomwe zidafika pachimake pakuchulukirachulukira komwe kukukulirakulira motsogozedwa ndi kafukufuku yemwe akupitilizabe kupitilira malire omwe amayembekeza pa nthawi ya moyo wa Alfred Einhorn zomwe sizinali zoyembekezeka kutha motero kutha kwaulendo wodabwitsa wogwirizanitsa mibadwo yamtsogolo padziko lonse lapansi.
