Umlando wokuthuthuka we-epoxy glass fibre drawing rod ungase ufise ukubheka lezi.

Induku yokudweba ingilazi ye-epoxy yenziwe nge-high-strength aramid fiber kanye ne-glass fiber ehlanganiswe ne-epoxy resin matrix ngokushisa okuphezulu kwe-pultrusion. Inezici zamandla aphezulu kakhulu, ukumelana okuhle kakhulu kokugqoka, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala nokunye ukumelana okuhle kakhulu kwezinga lokushisa eliphezulu. Imikhiqizo ifanele izitshalo ze-aluminium electrolytic, izitshalo zensimbi, imishini yensimbi ephezulu yokushisa, imishini kagesi ye-UHV, amasimu we-aerospace, ama-transformers, ama-capacitor, ama-reactors, amaswishi aphezulu-voltage nezinye izinto zikagesi ezinamandla kakhulu.

Kusukela ngo-1872, usokhemisi waseJalimane u-A.Bayer waqala wathola ukuthi i-phenol ne-formaldehyde zingakha ngokushesha izigaxa ezibomvu ngokunsundu noma izinto ze-viscous lapho kushisa ngaphansi kwezimo ezine-asidi, kodwa ukuhlolwa kwamiswa ngoba azikwazanga ukuhlanzwa ngezindlela zakudala. Ngemva kwekhulu lama-20, i-phenol iye yatholwa ngobuningi etiyela lamalahle, kanti i-formaldehyde nayo ikhiqizwa ngobuningi njengesivimbeli. Ngakho-ke, umkhiqizo wokusabela walaba ababili ukhanga kakhulu. Kwethenjwa ukuthi imikhiqizo ewusizo ingathuthukiswa, nakuba abantu abaningi besebenzise umsebenzi omningi kukho. , Kodwa akekho kubo owazuza imiphumela elindelekile.

Ngo-1904, u-Baekeland nabasizi bakhe nabo benza lolu cwaningo. Inhloso yokuqala kwakuwukwenza i-varnish evikelayo esikhundleni se-resin yemvelo. Ngemva kweminyaka emithathu yokuzikhandla, ekugcineni ehlobo lika-1907, akwenziwanga nje kuphela ukuvanisha okugqugquzelwayo. Futhi yakhiqiza izinto zokwakha zangempela zepulasitiki-i-Bakelite, eyaziwa kakhulu ngokuthi “i-bakelite”, “i-bakelite” noma i-phenolic resin.

Lapho i-Bakelite iphuma, ngokushesha abakhiqizi bathola ukuthi ayikwazi ukwenza kuphela imikhiqizo ehlukahlukene yokushisa kagesi, kodwa futhi yenza izidingo zansuku zonke. U-Edison (T. Edison) wayejwayele ukwenza amarekhodi, futhi ngokushesha wamemezela esikhangisweni: Wenze izinkulungwane zemikhiqizo nge-Bakelite. Imikhiqizo enjalo, ngakho-ke ukusungulwa kwe-Baekeland kwadunyiswa ngokuthi “i-alchemy” yekhulu lama-20.

Usokhemisi waseJalimane u-Beyer naye wenze umnikelo omkhulu ekusetshenzisweni kwe-bakelite.

Ngolunye usuku ngo-1905, usokhemisi waseJalimane u-Beyer wenza ucwaningo nge-phenol ne-formaldehyde eflaskini, futhi wathola ukuthi kwakwakhe into enamathelayo kuyo. Wayigeza ngamanzi wahluleka ukuyigeza. Kunalokho, wasebenzisa uphethiloli, utshwala namanye amakhemikhali emvelo. I-Solvent, namanje ayisebenzi. Lokhu kwenza ubuchopho bukaBeyere bube nzima. Kamuva, wazama konke okusemandleni akhe ukususa le nto “ecasulayo”. Aphefumulele phezulu uBeyere, awuphose emgqonyeni wezibi. ngaphakathi.

Ezinsukwini ezimbalwa kamuva, uBeyere wayesezolahla okuqukethwe komgqomo kadoti. Ngaleso sikhathi, waphinde wabona ucezu. Ubuso babushelelezi futhi bucwebezela, bucwebezela obukhangayo. UBeyere wayikhipha ngelukuluku. Ngemva kokuwoswa emlilweni, alisathambanga, lawela phansi, alizange liphuke, lalibona ngesaha, lagawulwa kahle, futhi uBeyer obukhali wacabanga ngokushesha ukuthi lokhu kungase kube uhlobo lwezinto ezintsha ezinhle kakhulu. .
