Omulimu ki ogw’ebiziyiza mu nkola y’okwefuula polimeeri eya hydroxyethyl acrylate?
Okusobola okukola ensengekera y’okwefuula (self-polymerization reaction), ebbugumu erisaanira lyetaagibwa okusooka. Okutwalira awamu, ebbugumu ery’okwefuula ery’okukola polimeeri ya hydroxyethyl acrylate KIRUNGI eri wakati wa 30°C ne 60°C. Singa ebbugumu liba wansi nnyo, enzirukanya ejja kuba mpola nnyo oba wadde obutabaawo. Singa ebbugumu liba waggulu nnyo, ensengekera eyinza okufuuka ey’effujjo ennyo, ekizibuwalira okufuga enkola y’ensengekera era ne kivaamu ebivaamu ebitali binywevu. N’olwekyo, okufuga ebbugumu kikulu nnyo! Ng’oggyeeko ebbugumu, ekitangaala nakyo kintu kikulu. Hydroxyethyl acrylate ekola nnyo ku kitangaala kya ultraviolet (UV), era ekitangaala kya UV kisobola okutumbula okukutuka kw’enkolagana yaakyo ey’emirundi ebiri, bwe kityo ne kitandika enkola ya polimeeri. Wansi w’obusannyalazo bwa UV, okwefuula polimeeri ya hydroxyethyl acrylate hea kujja kuba kwa mangu nnyo. Singa tukozesa ettaala ya UV oba okugiteeka mu musana, ejja kwefuula ey’amangu. Teebereza, wansi w’omusana, molekyu zino ziringa ezizina, nga zeegatta mangu ne zikola ebintu ebipya. Ng’oggyeeko ebbugumu n’ekitangaala, okulonda ekirungo ekiziyiza (catalyst) nakyo kikwata ku sipiidi n’ekikolwa ky’ensengekera y’okwefuula (self-polymerization reaction). Tujja kwongerako ebirungo ebimu ebiziyiza perokisayidi, nga haidrojeni perokisayidi, oba ebirungo bya azo nga azobisisobutyronitrile (AIBN). Ebiziyiza bino bisobola bulungi okukendeeza ku bbugumu ly’okutandika ery’ensengekera y’okwefuula polimeeri, ekigisobozesa okugenda mu maaso obulungi ne ku bbugumu erya wansi. Ddala zikola nga accelerators! Awatali kiziyiza, ensengekera eyinza okuba empola ennyo oba n’obutabaawo. N’olwekyo, omulimu gw’ekirungo ekiziyiza (catalyst) mu nsengekera y’okwefuula (self-polymerization reaction) teguyinza kubuusibwa maaso.
