Ensonga ki eziviirako obuveera bwa PVC okumyufu?

Okufuuka kwa kyenvu kwa pulasitiika kitegeeza enkola y’olujegere lw’olujegere lwa molekyu olulinga olujegere olumenya wansi w’ebbugumu eringi, obutonde bw’okwokya, oba wansi w’ekikolwa kya ultraviolet, infrared, ne microorganisms, ekivaako okwekutula kwa free radical.

Obuveera obutera okubeera mu buveera businga kuzingiramu bino wammanga:

1. Emisinde gya ultraviolet .

Ekitangaala ekibunye enjuba okutuuka ku layeri y’empewo ey’ebweru ye spectrum egenda mu maaso nga erina obuwanvu bw’amayengo obwa 0.7-3000nm, nga ku zino 300-400nm ultraviolet radiation kye kisinga okuvaako polymer okuvunda. era amasoboza ga fotoni mu ultraviolet range ya 290-400nm ga 300-419kJ/e, nga gano gasinga amaanyi g’enkolagana y’ebimu ku biyungo bya kemiko ebya bulijjo mu polimeeri.

2. Enkola y’okutebenkeza ebbugumu .

Ebitereeza ebbugumu eby’enjawulo birina ebikolwa eby’enjawulo ku nnywevu y’ekitangaala kya PVC.

Ebirungo bya BA/CD ne organotin carboxylate (nga maleic anhydride ester organotin stabilizers) bisobola okuwa degree ezimu ez’obutebenkevu bwa UV ku PVC profiles ezikozesebwa ebweru, ate ekirungo kya sulphur ekirimu ekirungo kya organotin (nga sulfur alcohol organic tin stabilizers) ekitangaala ekitono. Obunywevu bw’ekitangaala bw’ekiziyiza eky’omunnyo gwa di-salt businga ku bwa tri-salt lead stabilizer.

3. Enkola y’enkola y’okuziyiza obuwuka obuleeta obulwadde bwa siriimu .

Mu kiseera kino, ebinyweza ebikozesebwa abakola PVC profile okusinga biba binyweza ebikozesebwa (composite stabilizers). Ng’oggyeeko ekirungo ekikulu ekitebenkeza okuvunda kwa PVC, era mulimu enkola ezisiiga, enkola z’okuziyiza obuwuka obuleeta obulwadde n’enkola endala ezitebenkeza.

Enkola ya antioxidant eyinza okuli phenolic stabilizers ne phosphite co-stabilizers. Ebirungo bino biyinza okubaamu obucaafu obw’obutonde obwangu obukyuse langi, era okugatta ku ekyo, biyinza okuyita mu nkola z’okukyusakyusa langi wansi w’ekikolwa ky’ekitangaala, okisigyeni, n’amazzi.
