Resine za epoxy ni ingenzi mu nganda zitandukanye, kuva ku gukora ibikoresho bivanze kugeza ku gukora kole zihariye. Mu bintu by'ingenzi bigaragaza izi resine, viscosity igaragara nk'ikintu cy'ingenzi—kigira ingaruka zikomeye ku mikorere yazo, uburyo zikoreshwa, ndetse n'imikorere myiza y'ibicuruzwa bya nyuma.
Uburyo bwo gukora Epoxy Resin
1.1 Intambwe z'ingenzi mu gukora
Gukora resine za epoxy ni inzira yo guhuza ibinyabutabire mu byiciro byinshi. Ishingiro ry'iyi nzira ni ukugenzura neza imiterere y'ibinyabutabire kugira ngo ibikoresho fatizo bihindurwemo resine z'amazi zifite imiterere yihariye ya fiziki. Uburyo busanzwe bwo gukora ibintu butangirana no kugura no kuvanga ibikoresho fatizo, cyane cyane bisphenol A (BPA), epichlorohydrin (ECH), sodium hydroxide (NaOH), n'ibintu bishongesha nk'isopropanol (IPA) n'amazi yakuwemo iyoni. Ibi bintu bivangwa mu ruganda rwabanje kuvanga ku gipimo nyacyo mbere yo kwimurirwa mu cyuma gitanga umusaruro kugira ngo habeho polimerize.
Uburyo bwo guhuza ibintu muri rusange bukorwa mu ntambwe ebyiri kugira ngo habeho impinduka nziza kandi umusaruro uhamye. Mu gice cya mbere cy'ingufu,hidroksidi ya sodiyumuYongerwaho nk'umusemburo, hanyuma igisubizo kigakomeza kuri dogere 58 kugira ngo kigere ku ihinduka rya 80%. Hanyuma icyo gicuruzwa cyimurirwa mu cyuma cya kabiri, aho isosi ya hydroxide isigaye yongerwamo kugira ngo ihindurwe burundu, bigatanga resin ya epoxy ya nyuma. Nyuma ya polymerization, hakorwa urukurikirane rw'intambwe zikomeye zo gutunganya nyuma. Ibi birimo gusukamo amazi ya sodium chloride (NaCl) hamwe n'amazi yakuwemo iyoni kugira ngo habeho urwego rw'amazi meza, hanyuma rukavanwa mu cyiciro cy'ibinyabuzima gikungahaye kuri resin hakoreshejwe uburyo bwo gutwara cyangwa gupima turbidity. Uru rundi rw'isuku rwa resin rukomeza gutunganywa binyuze mu byuma bihindura imiterere y'amazi cyangwa inkingi zo gusya kugira ngo hagaruzwe epichlorohydrin yarenze, bigatuma habaho umusaruro wa nyuma wa epoxy resin y'amazi meza.
1.2 Kugereranya ibikorwa by'umusaruro w'itsinda ugereranije n'ibikorwa bihoraho
Mu gukora resin ya epoxy, uburyo bwo gukora bugizwe n'ibice byinshi n'ubudasibangana bufite ibyiza n'ibibi bitandukanye, biganisha ku itandukaniro ry'ibanze mu byo bakeneye mu kugenzura ubukana bw'ibice. Gutunganya ibintu bitandukanye bikubiyemo gutanga ibikoresho fatizo mu cyuma gitunganya ibintu bitandukanye, aho binyura mu buryo butandukanye bw'ibinyabutabire n'ubushyuhe. Ubu buryo bukunze gukoreshwa mu gukora ibintu bito, mu buryo bwihariye, cyangwa mu bicuruzwa bifite ubwoko butandukanye, bitanga ubushobozi bwo gukora resin zihariye zifite imiterere yihariye. Ariko, gukora ibintu bitandukanye bifitanye isano n'imikorere miremire no kudahuza kw'ubwiza bw'ibicuruzwa bitewe no gukoresha intoki, guhindagurika kw'ibikoresho fatizo, no guhinduka kw'imikorere. Iyi ni yo mpamvu abahanga mu gukora ibintu n'imikorere bakunze kugaragaza ko "guhuza ibintu mu buryo budakwiye" ari ikibazo gikomeye.
Ku rundi ruhande, umusaruro uhoraho ukora neza ukoresheje ibikoresho n'ibicuruzwa bihoraho binyuze mu ruhererekane rw'ibikoresho bihuza, pompe, n'ibikoresho bihindura ubushyuhe. Ubu buryo bukundwa cyane ku nganda nini n'ibikenewe cyane, bitanga umusaruro mwiza kandi uhoraho bitewe na sisitemu zo kugenzura zikoresha ikoranabuhanga zigabanya ihindagurika ry'imikorere. Nyamara, ibikorwa bihoraho bisaba ishoramari ryinshi ry'ibanze n'uburyo bugezweho bwo kugenzura kugira ngo hakomeze kubaho ituze.

Mu gihe cy'ihinduka ry'imikorere y'itsinda, impinduka muriubukana bwa epoxy resinbigaragaza neza iterambere ry’iminyururu ya molekile n’uburyo bwo guhuza. Mu ntangiriro, uko ubushyuhe buzamuka, ubushyuhe bwa epoxy resin bugabanuka bitewe n’ingufu za molekile ziyongera. Ariko, uko reaction ya polymerization itangira kandi umuyoboro uhuza ibintu mu buryo butatu ugakora, ubushyuhe buriyongera cyane kugeza igihe ibikoresho bikize neza. Mu gukurikirana ubushyuhe buri gihe, abahanga bashobora gukurikirana neza iterambere ry’ibisubizo no kumenya neza aho reaction igarukira. Ibi ntibibuza gusa ko ibikoresho bikomera imbere muri reactor, byasaba gukuraho intoki bihenze kandi bigatwara igihe kinini, ahubwo binatuma umusaruro wa nyuma wuzuza uburemere bwa molekile n’imikorere yawo.
Byongeye kandi, ubukana bugira ingaruka zitaziguye ku ikoreshwa ry’amazi mu gice cyo hasi no mu buryo bwo kuyatunganya. Urugero, mu ikoreshwa ry’ibirahure, kole, no mu gusya, ubukana bugena imikorere ya resin mu mitsi, uburyo ikwirakwira, n’ubushobozi bwayo bwo kurekura uduce tw’umwuka twafashwe. Resin zifite ubukana buke bworohereza gukuraho uduce tw’umwuka kandi zishobora kuzuza icyuho gito, bigatuma zikoreshwa mu gusuka cyane. Resin zifite ubukana bwinshi, mu buryo butandukanye, zifite ubushobozi bwo kudatonyanga cyangwa kudacika intege, bigatuma ziba nziza ku buso buhagaze cyangwa mu gufunga.
Bityo rero, gupima ubukana bw'ibice bitanga ubumenyi bw'ibanze ku ruhererekane rwose rw'ikorwa rya epoxy resin. Mu gushyira mu bikorwa igenzura ry'ubukana bw'ibice bicucucucu mu buryo bufatika kandi bufatika, inzira yose yo gukora ishobora gusuzumwa no kunozwa mu buryo bufatika mu gihe nyacyo.
