Glue ya PVC ye adhesive eyakolebwa mu ngeri ey’enjawulo okusiba ebintu bya polyvinyl chloride (PVC). Kikozesebwa nnyo mu kusiba payipu z’obuveera, firimu, profile, n’ebintu ebirala. Omulimu gwayo omulungi ogw’okukwatagana okusinga guva ku butonde bwayo obw’enjawulo obw’eddagala n’ensengekera eyakolebwa mu ssaayansi.
Ebitundu ebikulu ebya PVC glue mulimu solvent, plasticizer, resin, ne stabilizer. Ekizimbulukusa kye kimu ku bitundu ebikulu ebya kalaamu, mu ngeri entuufu ebizimbulukusa ebiramu nga asetoni, toluene, ne methylene chloride. Ebizimbulukusa bino bisaanuusa bulungi ezimu ku njegere za molekyu ku ngulu wa PVC, ne zizigonza era ne zinyweza enkolagana wakati wa kalaamu ne substrate. Oluvannyuma lw’okusiiga, ekizimbulukusa kifuumuuka mpolampola, ekivaako oluwuzi olusiiga okukaluba, ne lukola ekiyungo eky’amaanyi.
Ebiveera, nga dioctyl phthalate (DOP) oba epoxidized soya oil, bikozesebwa okulongoosa okukyukakyuka n’okunywerera kw’ebintu bya PVC. Ebiveera biyingira wakati w’enjegere za molekyu za PVC, ne bikendeeza ku bbugumu lyayo ery’enkyukakyuka y’endabirwamu, ekyanguyira kalaamu okuyungibwa ku ngulu wa PVC n’okulongoosa amaanyi g’enkolagana.
Resin kye kitundu ekirala ekikulu mu PVC adhesive. Ebyokulabirako ebimanyiddwa mulimu vinyl chloride-vinyl acetate copolymer (PVAC) oba polyisocyanate (PU) resins. Resin zino zikola firimu enkalu ey’okusiiga oluvannyuma lw’ekizimbulukusa okufuumuuka, ne kiwa amaanyi g’okukwatagana agawangaala-. Ebimu ku bikwata ku PVC ebikola obulungi-nabyo biyinza okubaamu acrylates oba epoxy resins okutumbula okuziyiza amazzi n’eddagala.
Okugatta ku ekyo, ebinyweza nga calcium zinc stabilizers oba organotin compounds bikozesebwa okuziyiza PVC okuvunda wansi w’ebbugumu eringi oba UV, okukakasa nti ekyesiiga kinyweza okumala ebbanga eddene.
Mu bufunze, omulimu gw’okusiba ebizigo bya PVC gusinziira ku busobozi bw’ekizimbulukusa okusaanuusa PVC, ekigonza ky’ekirungo kya pulasitiika, obusobozi bwa resin okukola firimu-, n’obuwangaazi bw’ekinyweza. Enkola ez’enjawulo ez’okusiiga PVC zisaanira okukozesebwa okw’enjawulo, gamba ng’okusiba amangu-, okugumira ebbugumu eringi-, oba ebizigo ebikyukakyuka, okusobola okutuukiriza ebyetaago by’amakolero eby’enjawulo.
