PVC Stabilizers of the Past, eriwo, n’ebiseera eby’omu maaso .

Bwe baazuulibwa ebirungo ebigattibwa mu kemiko ebisobola okukendeeza ku kufiirwa kw’ebintu eby’eddagala n’eby’omubiri eby’ebbugumu-ebikolebwa naye ebbugumu-ekiwujjo ekiwulizi ekiyitibwa poly(vinyl chloride) (PVC), amakolero gaazaalibwa. Era nga girima ensi y’ebirungo ebigattibwa mu buveera. Stabilizers for PVC zafuuka era amakolero gennyini, nga baliisa ne baziri mu makolero gano aga versatile polymer, mu nkolagana kumpi ey’okukwatagana. Wabaddewo ebika by’ebitebenkedde bingi nnyo ebikozesebwa mu myaka ataano egiyise: inorganics, leads, organics, barium/cadmiums, calcium/zincs, organotins, ne antimony. Era bwekityo bangi nnyo balowooleza naye nga tebatunda: organoleads, organoantimonys, bismuths, indiums, n’eddagala eritali ddene ery’obutonde. Birungi ki n’ebbula ly’ebintu bino ebitebenkedde? Ate ebintu by'eggulo bikyali naffe? Ebika ebipya bye biruwa? Ebintu eby’enkya biyinza kuba bitya? Olupapula luno lujja kugezaako okwetegereza n’okukubaganya ebirowoozo ku by’emabega, ebiriwo, n’ebiseera eby’omu maaso eby’ebitereeza PVC; Ensonga ezivunaanyizibwa ku ngeri zaabwe, okufuga okunoonyereza kwabwe, okukulaakulanya, n’okutunda, n’engeri ensonga zino gye zikyuka n’obudde.
