Iglu yePVC, into encamathelayo ekhethekileyo eyilelwe ngokukodwa ukudibanisa i-polyvinyl chloride (i-PVC) imathiriyeli, ibambe ixabiso lobugcisa elingenakuphinda lifumaneke kwiindawo ezifana nokusetyenzwa kwemveliso yeplastiki, ukuhonjiswa kwezakhiwo, kunye nokugcinwa kwemizi-mveliso. Iimpawu zayo zobugcisa zibonakaliswa ikakhulu kule miba ilandelayo:
Ngokwembono yekhemikhali,{0}}umgangatho ophezulu weglu zePVC zisebenzisa isinyibilikisi{1}esekwe okanye kwimixube esebenzayo. I-Solvent-esekelwe kwiimveliso zisebenzisa izinyibilikisi eziphilayo ezifana ne-dichloromethane kunye ne-cyclohexanone njenge-matrix yazo, ukunyibilikisa iimolekyuli zomphezulu ze-PVC ukwenza umaleko wenguqu ye-viscous. Izinto zokuncamathelisa ezisebenzayo, kwelinye icala, ziqulathe i-polyurethane okanye i-acrylate prepolymers ezihamba umnqamlezo{5}}ukudibanisa ngexesha lenkqubo yokunyanga, zenza ubume bothungelwano{6} olunemilinganiselo emithathu. Olu yilo lwahlukileyo lweekhemikhali lubavumela ukuba baziqhelanise neemeko zokusebenza ezahlukeneyo.
Ngokubhekiselele kwintsebenzo yokudibanisa, iglue yePVC ibonisa ukuhambelana kwezinto ezibonakalayo. Idatha yovavanyo ibonisa ukuba-iiglu zebakala zibonisa amandla okucheba ka-5-8 MPa kunye namandla amaxolo angaphezulu kwe-3 N/mm kwi-PVC, agqithise kakhulu ukusebenza kwento encamathelayo yeenjongo zonke eziqhelekileyo. Ukuqulunqwa kwabo okukhethekileyo kwe-agent agent ingena ngokukhawuleza kwi-microporous structure ye-PVC surface, iqinisekisa ukudibanisa okuthembekileyo nakwi-substrates e-oyile egudileyo okanye encinci. Ezinye iimveliso eziguquliweyo zikwabonelela ngokumelana nobushushu (izinzile ukusuka kwi-20℃ukuya kwi-80 degree) kunye nokumelana nemichiza.
Ngokubhekiselele kwisicelo sobugcisa, i-PVC yokuncamathela yanamhlanje iphumelele impumelelo ebalulekileyo ekuphuculeni inkqubo. Ngokukhawuleza-imveliso zokomisa zinexesha{2}}elisimahla le-3{6}}imizuzu emi-5, kunye nexesha elipheleleyo lokunyanga elingekho ngaphezulu kweeyure ezingama-24. Amachiza{9}}evumba eliphantsi agcina amanqanaba e-VOC ngaphantsi kwe-50g/L, ethobela imigaqo ye-EU REACH. Ukudibanisa{11}}imibhobho yePVC ebiyelwe ngodonga okanye iprofayile, izinto zokuncamathelisa zethixotropic zenziwe. Ukongezwa kwe-nano-thickeners kuvumela ukusetyenziswa okuchanekileyo, okujoliswe kuyo kwaye kugweme iziphene zokuhamba.
Kubalulekile ukuba uqaphele ukuba ukhetho lwe-PVC yokunamathela kufuneka luhambelane ngokusondeleyo nesicelo esithile. Ukunyibilikisa -izinto zokuncamathelisa ezisekelwe kwisokethi{2}}kunye{3}}nenkqubo ye-spigot ye-spigot iyacetyiswa ngokudibanisa imibhobho ye-PVC eqinileyo, ngelixa i-elastomer{4}}izinto zokuncamathelisa ezilungisiweyo zikhethwa kwiifilim ezithambileyo. Ngokunyuka kweemfuno zokhuseleko lokusingqongileyo, amanzi{6}izinto zokuncamathelisa zePVC ezisekwe zisiba yindawo yophando nophuhliso. Ukungeniswa kwamanzi{8}okusekelwe kwi-polyurethane dispersions kunciphisa kakhulu impembelelo yokusingqongileyo ngelixa kugcinwa amandla ebhondi.
Uphuhliso lwangoku lobuchwepheshe lubonisa ukuba izinto zokuncamathelisa ezikrelekrele zePVC (ezifana nobushushu-ukunyanga okunobuzaza kunye ne-UV{1}}i-triggered crosslinking) yenza inkqubela elabhoratri kwaye inokuqhuba inkqubo yokudityaniswa kweemveliso ze-PVC ekufezekiseni nasekuchanekeni okukhulu. Ezi zinto zintsha zeteknoloji ziyaqhubeka nokuhlanganisa isikhundla esibalulekileyo se-PVC yokunamathela kwishishini lokulungisa iiplastiki.
