Iglue ye-PVC, ingcina ekhethekile eklanyelwe ngokukhethekile ukuhlanganisa izinto ze-polyvinyl chloride (PVC), ibamba inani lobuchwepheshe elingenakuthathelwa indawo emikhakheni efana nokucutshungulwa komkhiqizo wepulasitiki, umhlobiso wezakhiwo, nokugcinwa kwezimboni. Izici zayo zobuchwepheshe ziboniswa ngokuyinhloko kulezi zici ezilandelayo:
Ngokombono wamakhemikhali,-amaglue e-PVC ekhwalithi ephezulu ngokuvamile asebenzisa ukwakheka okuncibilikisiwe{1}okusekelwe noma okusebenzayo. Imikhiqizo encibilikisiwe{{3}isebenzisa izincibilikisi zemvelo ezifana ne-dichloromethane ne-cyclohexanone njenge-matrix yazo, incibilikisa ama-molecule angaphezulu e-PVC ukuze akhe isendlalelo soguquko se-viscous. Ama-adhesive asebenzayo, ngakolunye uhlangothi, aqukethe i-polyurethane noma ama-acrylate prepolymers ahlangana-nokuxhumanisa phakathi nenqubo yokwelapha, akha isakhiwo senethiwekhi{6}}esintathu. Lo mklamo wamakhemikhali ohlukene ubavumela ukuthi bavumelane nezimo ezihlukahlukene zokusebenza.
Mayelana nokusebenza kokubopha, i-PVC glue ibonisa ukuhambisana okuhle kakhulu kwezinto. Idatha yokuhlola ibonisa ukuthi -ama-glues ebanga abonisa amandla okugunda angu-5-8 MPa namandla ekhasi adlula u-3 N/mm ku-PVC, adlula kude ukusebenza kwezinamatheliso ezihlosiwe ezivamile. Ukwakheka kwe-ejenti yabo yokumanzisa okukhethekile ingena ngokushesha esakhiweni se-microporous sendawo ye-PVC, iqinisekisa ukubopha okuthembekile ngisho nasezindaweni ezingaphansi ezibushelelezi noma ezinamafutha amancane. Eminye imikhiqizo eguquliwe iphinde inikeze ukumelana nezinga lokushisa (elizinzile ukusuka ku -20℃kuya ku-80℃) kanye nokumelana namakhemikhali.
Mayelana nokusetshenziswa kwezobuchwepheshe, izinto zokunamathisela zesimanje ze-PVC zithole impumelelo enkulu ekusebenzeni kahle kwenqubo. Imikhiqizo esheshayo-eyomisayo ine-tack{2}}isikhathi samahhala esingu-3-amaminithi angu-5, nesikhathi sokwelapha esigcwele esingeqi amahora angu-24. Ukwakhiwa kwephunga{9}eliphansi kugcina amazinga e-VOC engaphansi kuka-50g/L, ethobela imithetho ye-EU REACH. Ukuze kuhlanganiswe{11}}amapayipi{11}}e-PVC anezindonga noma amaphrofayela aqinile, okunamathelayo kwe-thixotropic kwenziwe. Ukwengezwa kwama-nano-thickeners kuvumela ukusetshenziswa okunembile, okuhlosiwe futhi kugwema ukukhubazeka kokugeleza.
Kubalulekile ukuqaphela ukuthi ukukhetha kwe-PVC okunamathelayo kufanele kuhambisane eduze nesicelo esithile. Okunamatheliswayo okuncibilikisiwe{1}okunesokhethi{2}}kanye{3}}nenqubo yokuhlanganyelwa kwe-spigot kuyanconywa ukuze kuhlanganiswe amapayipi aqinile e-PVC, kuyilapho ama-elastomer{4}}okunamathelisa alungisiwe ekhethwa ngokubopha amafilimu athambile. Ngokukhula kwezidingo zokuvikela imvelo,{{6}izinto zokunamathisela ze-PVC ezisuselwe emanzini seziphenduka indawo yocwaningo nentuthuko. Ukwethulwa kwamanzi{8}okusekelwe ku-polyurethane dispersions kunciphisa kakhulu umthelela wendawo ngenkathi kugcinwa amandla ebhondi.
Intuthuko yamanje yobuchwepheshe ibonisa ukuthi izinto ezinamathelayo ze-PVC ezihlakaniphile (ezifana nezinga lokushisa-njengokwelapha okuzwelayo kanye ne-UV-i-triggered crosslinking) ziyathuthuka elabhorethri futhi zingaqhuba inqubo yokuhlanganisa imikhiqizo ye-PVC ekusebenzeni kahle nokunemba okukhulu. Lezi zindlela ezintsha zobuchwepheshe ziyaqhubeka nokuhlanganisa isikhundla esibalulekile sokunamathela kwe-PVC embonini yokucubungula amapulasitiki.
