Ngaba iPolyurethane sealant ingcono kuneSilicone?
Umgangatho ophezulu kunye nendalo engqongqo ye-polyurethane sealants ibanika inzuzo encinci ngaphezu kweepropati ezihlala ixesha elide ze-silicone.
Nangona kunjalo, nokuba i-polyurethane sealant ingcono kune-silicone sealant ixhomekeke kwisicelo esithile kunye neemfuno. Nazi ezinye iiyantlukwano eziphambili ekufuneka ziqwalaselwe:
Ukuncamathela: Polyurethane sealantsngokubanzi ube nokuncamathela ngcono kwimigangatho eyahlukeneyo ebanzi, kubandakanywa umthi, isinyithi, kunye nekhonkrithi, ezenza zilungele izicelo ezifuna kakhulu.
Ukuba bhetyebhetye:Zombini izitywini zibonelela ngokuguquguquka, kodwa i-polyurethane ithande ukunwebeka ngakumbi, ivumela ukuba ifunxe intshukumo engcono, enenzuzo kwiindawo eziphantsi kokwandiswa kunye nokuncipha.
Ukuqina:Ii-polyurethane sealants zihlala zihlala ixesha elide kwaye zixhathisa kwi-abrasion, iikhemikhali, kunye nokuvezwa kwe-UV, zizenza zilungele ukusetyenziswa kwangaphandle nakwimizi-mveliso.
Ukumelana naManzi:Zombini ezi ntlobo zibonelela ngokumelana namanzi okulungileyo, kodwa izitywini ze-polyurethane zihlala zisebenza ngcono kwiimeko ezimanzi kwaye zinokumelana nokuvezwa ixesha elide kukufuma.
Ixesha lokuphumla:Izitywini ze-silicone zihlala ziphilisa ngokukhawuleza kune-polyurethane sealants, enokuba luncedo kwiiprojekthi ezithatha ixesha.
Ubuhle:Izitywini ze-Silicone zifumaneka kuluhlu olubanzi lwemibala kwaye zinokubonakala zithandeka ngakumbi kwizicelo ezibonakalayo, ngelixa i-polyurethane sealants inokufuna ukupeyinta ukujonga okugqityiweyo.
Ukumelana nobushushu: Izitywini ze-silicone ngokubanzi zinokumelana nobushushu obuphezulu, zizenza zilungele izicelo ezivezwe kubushushu obugqithisileyo.
