Iglue ye-PVC iyingcina eklanyelwe ngokukhethekile ukuhlanganisa izinto ze-polyvinyl chloride (PVC). Isetshenziswa kabanzi ekuhlanganiseni amapayipi epulasitiki, amafilimu, amaphrofayili, neminye imikhiqizo. Ukusebenza kwayo okuhle kakhulu kwesibopho ngokuyinhloko kungenxa yokwakheka kwayo kwamakhemikhali okuhlukile kanye nefomula eyakhiwe ngokwesayensi.
Izingxenye eziyinhloko zeglue ye-PVC zifaka i-solvent, i-plasticizer, i-resin, ne-stabilizer. I-solvent ingenye yezingxenye eziyinhloko zeglue, ngokuvamile izincibilikisi eziphilayo njenge-acetone, i-toluene, ne-methylene chloride. Lezi zincibilikisi zihlakaza ngokuphumelelayo amanye amaketanga e-molecular ebusweni be-PVC, ziwathambisa futhi ziqinise isibopho phakathi kweglue ne-substrate. Ngemuva kokufaka isicelo, i-solvent iyancipha kancane kancane, ibangele ungqimba lwe-adhesive ukuba luqine, lwakha isibopho esiqinile.
Ama-Plasticizers, njenge-dioctyl phthalate (DOP) noma uwoyela we-soya epoxidized, asetshenziselwa ukuthuthukisa ukuguquguquka nokunamathela kwezinto ze-PVC. Ama-Plasticizer angena phakathi kwamaketanga e-PVC amangqamuzana, ehlisa izinga lokushisa lokushintsha kwengilazi, okwenza kube lula ukuthi ingcina ihlangane ne-PVC futhi ithuthukise amandla ebhondi.
I-resin ingenye ingxenye ebalulekile yokunamathela kwe-PVC. Izibonelo ezijwayelekile zifaka i-vinyl chloride-vinyl acetate copolymer (PVAC) noma ama-polyisocyanate (PU) resins. Lawa ma-resin akha ifilimu enamathelayo eqinile ngemva kokuba i-solvent ihwamukile, inikeze{3}}amandla ebhondi ahlala njalo. Ezinye{5}}ezinamathelisa i-PVC ezisebenza phezulu zingase futhi ziqukathe ama-acrylates noma ama-epoxy resins ukuze kuthuthukiswe ukumelana namanzi namakhemikhali.
Ngaphezu kwalokho, iziqinisi ezifana nezinzinzisi ze-calcium zinc noma izinhlanganisela ze-organotin zisetshenziselwa ukuvimbela i-PVC ukuthi ingaboli ngaphansi kwamazinga okushisa aphezulu noma ukuchayeka kwe-UV, okuqinisekisa{0}}ukuzinza kwesikhathi eside kokunamathelayo.
Kafushane, ukusebenza kwebhondi kokunamathelayo kwe-PVC kuncike emandleni wesincibilikisi sokuncibilikisa i-PVC, umphumela wokuthambisa we-plasticizer, ikhono lokwenza ifilimu ye-resin-, kanye nokuqina kwesiqinisi. Ukwakhiwa okunamathelayo okuhlukile kwe-PVC kulungele izinhlelo zokusebenza ezihlukene, njengokubopha okusheshayo-okunamathelayo,{3}}okuphezulu{3}}okunamathelisa okushisa-okungazweli, noma okuvumelana nezimo, ukuhlangabezana nezidingo zezimboni ezihlukahlukene.
