Evolutionary nhoroondo ye eptfe indasitiri

Iko kushanduka kweiyo eptfe indasitiri inyaya inonakidza yakagadziridzwa nekufamba kwenguva kugadzira indasitiri ine revolutionary application.Nhoroondo ye epoxy inotanga muna 1884, apo chemist Alfred Einhorn akagadzira mutsva mutsva kubva ethylene uye formaldehyde.Komisheni iyi yainzi "epoxide", iyo yakazozivikanwa se epoxy nekuisanganisa ne polyol kana esters.Kunyange zvazvo kuumbwa kwepakutanga uku kwaiva nekushanda kwakawanda, kushandiswa kwayo kwakaramba kuine zvishoma nekuda kwekudhura kwayo uye kushayikwa kwezvinhu zviripo.Mumakore ekuma1940 vatsvakurudzi vakati wandei vakashanda pakuvandudza maumbirwo ekutanga epoxy kusanganisira American Richard Condon akawana kuti angaite sei kuti igare yakasimba achishandisa mapolols anobva muzvigadzirwa zvepetroleum secyclohexane oxide uye phenol novolak resin.Panguva imwe cheteyo masayendisiti eBritain akatanga kuyedza nemishonga yakasiyana-siyana yakaita semaamine nemaasidhi zvichikonzera chigadzirwa chakavandudzwa chaigona kushandiswa pakuisa marara senge plywood ichiita kuti ive yakasimba kupfuura kare nekudaro kugadzira nzira dzemazuva ano macomposites ekugadzira zvinhu.Munguva yeHondo Yenyika II zvikumbiro zvemauto zveepoxies zvakawedzera zvakanyanya kugadzira kudiwa kwemagiredhi ari nani ezvezvinhu zvinotungamira vatengesi kuti vagadzire zvinhu zvakasarudzika senge kupisa kupisa, kuchinjika pakudziya kwakadzika, makemikari kuramba nezvimwewo, zvichivabvumira kuzadzisa zvinodiwa chaizvo mukugadzirwa kwezvikamu zvendege.Kuvandudzwa kweiyi tekinoroji kwakazoenderera mberi kusvika kuma1950 uko kufambiswa mberi kwakaitwa mumiviri yekugadzira resin dzekugadzira pamwe chete nedziya dzakagadzirwa pamwe chete pakati pechisikigo rabha & synthetic musanganiswa werabha wakasanganiswa nemafiller akaita seasbestos achigadzira izvo zvatave kuziva nhasi se 'yakazadzwa elastomers' kana. rubbers reinforced plastics (FRP).Pakazosvika ma1960 maitiro akasiyana akakwenenzverwa zvakaringana zvekuti maindasitiri egiredhi ekugadzira akawanda masisitimu anogona kuitwa achitungamira mberi kune kuwedzera mavara & zvimwe zvekuwedzera zvinopa kusimuka kwemazuva ano epoxies akagadziridzwa epoxies anoshandiswa mumaindasitiri akawanda kubva kuvaka & engineering kuburikidza nekugadzira mota kurudyi. kusvika nguva pfupi yadarika semiconductor packaging mhinduro dzakashandiswa dzakaomarara maumbirwo anoda chaiwo hupfu simbi yesimbi pakati pezvimwe pamwe neceramic coating tekinoroji inosanganisira madhaimani guruva zvidimbu zvinobvumira vanogadzira maturusi ekucheka kuti vakwanise kukwirira kusinganzwikwe makore makumi maviri chete isati yasvika.Iyi nguva inoratidza kuti takasvika papi kubva pakugadzirwa kwekutanga kumashure 1884 zvichisvika pakuwedzera kuoma kunzwisisa kuri kukura kwakagadziriswa nekuenderera mberi kushandura tsvakiridzo parizvino ichisundira miganhu inodarika chero tarisiro yepakutanga panguva yehupenyu hwaAlfred Einhorn yekuvhura mikana isina kumbobvira yarota zvichikwanisika nekudaro kupera kunoshamisa rwendo rwekushanduka-shanduka runobatanidza zuva razvino. kufambira mberi kunobatsira zvikuru zvizvarwa zvinotevera munyika yose .SB1A1101 SB1A1103
