Ni murimo ki gw’ebintu ebirikureetaho okuhinduka kw’ebintu omu kwehindura kw’ebintu ebirikwetwa hydroxyethyl acrylate?
Kugira ngu ekikorwa ky’okwehindura (self-polymerization) kibaho, nikyetengyesa obutagatsi obuhikire obw’okubanza. Omu bwijwire, omubaro gw’obutagatsi ahabw’okwehindura kw’amaizi g’omubiri (hydroxyethyl acrylate) . KIBONEIRE eri ahagati ya 30°C na 60°C. Ebiriisa byaba biri ahansi munonga, okugarukamu nikwija kuba mpora munonga nari nangwa kutabaho. Ebiriisa byaba biri ahaiguru munonga, okugarukamu nikubaasa kuba okw’amaani munonga, ekirikureetera kigumire kutegyeka omuringo gw’okugarukamu kandi kirugyemu ebintu ebitagumire. N’ahabw’ekyo, okurinda ebirikuba biriho ni kikuru munonga! Oyihireho obutagatsi, omushana nagwo n'ekintu kikuru. Hydroxyethyl acrylate neekora gye munonga aha mushana gwa ultraviolet (UV), kandi omushana gwa UV nigubaasa kutunguura okucwanyagura kw’enkoragana zaayo ibiri, obwo nigutandikaho okugarukamu kw’okukora ebiriisa. Ahansi y’okurabira omu mushana gwa UV, okwehindura kwa hydroxyethyl acrylate hea nikwija kurahuka munonga. Twakoresa etabaaza ya UV nari kugiteeka omu mushana gw’eizooba, neija kwehindura omu bwangu. Teekateeka, ahansi y’omushana gw’eizooba, obutafaari obu nibushusha nk’oburikuzina, burahuka kwegaita hamwe bukakora ebintu bisya. Oyihireho obutagatsi n’omushana, okutoorana ekirikureetaho okuhinduka kw’ebintu nakyo nikikwata aha mubaro n’ebirikuruga omu nkora y’okwehindura. Nitwija kwongyeraho ebimwe ebirikureetaho okusheeshasheesha, nk’okusheeshasheesha kw’amaizi, nari ebirungo bya azo nka azobisisobutyronitrile (AIBN). Ebirikureetaho okuhinduka kw’ebintu ebi nibibaasa kukyendeeza gye obutagatsi bw’okutandika kw’okukora kw’okwehindura, ekirikugibaasisa kugumizamu gye n’obu obutagatsi buri ahansi. Buzima nizikora nk’ebirikutunguura! Hatariho ekirikureetaho okuhinduka, okugarukamu nikubaasa kugyenda mpora munonga nari nangwa kutabaho. Nahabwekyo, omurimo gw’ekirungo omu nkora y’okwehindura tigurikubaasa kugaya.
