Xa kuziwa kwizixhobo zokutywina, kukho iintlobo ezintathu eziphambili zokutywina ezisetyenziswa rhoqo kwizicelo ezahlukeneyo:i-polyurethane, abicah, kwayeI-latex esekwe emanzini. Nganye kwezi zitywina zineepropati ezizodwa kwaye zifanelekile ukusetyenziswa okuhlukeneyo. Ukuqonda iimpawu zezi zitywini kubalulekile ekukhetheni isitywini esifanelekileyo kwiprojekthi ethile.
Polyurethane sealantszaziwa ngokomelela kwazo okukhethekileyo nokuba bhetyebhetye. Ngokuqhelekileyo zisetyenziselwa ukwakhiwa kunye nezicelo zoshishino apho kufuneka isitywina esinamandla, esihlala ixesha elide. Ii-polyurethane sealants zimozulu-, iikhemikhali-, kunye ne-abrasion-resistant, izenza zilungele ukusetyenziswa ngaphandle. Bayakwazi nokubambelela kwizinto ezahlukeneyo, kuquka ikhonkrithi, iinkuni, isinyithi kunye neplastiki. Ukongeza, i-polyurethane sealants inokumelana okugqwesileyo kwimitha ye-UV kwaye ifanelekile ukutywinwa kwamalungu kunye nezikhewu kwizakhiwo zangaphandle.
Izitywini zeSiliconezidume ngokuncamathela kwazo okugqwesileyo kunye nokuguquguquka. Ngokuqhelekileyo zisetyenziswa kwi-plumbing, i-automotive kunye ne-electronic applications ngenxa yokuchasana nomswakama kunye nokushisa okukhulu. Izitywini zeSilicone zikwayaziwa ngokukwazi kwazo ukuhlala zibhetyebhetye kuluhlu olubanzi lobushushu, zizenza zilungele ukusetyenziswa ngaphakathi nangaphandle. Zikwamelana nokukhula kokungunda kunye nokungunda, nto leyo ezenza zilungele ukutywina amalunga kwindawo ezifumileyo ezifana nezindlu zangasese kunye namakhitshi. Ukongeza, i-silicone sealants inezixhobo ezilungileyo zokukhusela umbane, ezenza ukuba zilungele ukutywinwa kwezinto zombane kunye nokudibanisa.
Amanzi asekelwe kwi-latex sealantszaziwa ngokusetyenziswa kwazo ngokulula kunye nokupeyinta. Ngokuqhelekileyo zisetyenziselwa izicelo zangaphakathi ezifana nokuvala izikhewu kunye neentanda kwiindonga, iifestile kunye neengcango. I-latex sealants esekelwe emanzini kulula ukuyicoca ngamanzi kwaye ibe nevumba eliphantsi, ibenze bafanelekele ukusetyenziswa kwangaphakathi. Zisenokupeyintwa ukuze zidibanise ngokungenamthungo kunye neendawo ezijikelezileyo. Nangona i-latex sealants esekelwe emanzini ayinakuhlala ixesha elide njenge-polyurethane okanye i-silicone sealants, iyona nto ikhethekileyo kwiiprojekthi zokutywinwa kwangaphakathi apho kulula ukusetyenziswa kunye ne-aesthetics ebalulekileyo.
Isishwankathelo, i-polyurethane, i-silicone, kunye ne-latex-based sealants ye-latex nganye ineempawu ezizodwa kwaye zifanelekile kwizicelo ezahlukeneyo. Ii-polyurethane sealants ziyaziwa ngokuqina kwazo kunye nokuxhathisa imozulu, zizenza zilungele ukusetyenziswa ngaphandle. Ii-silicone sealants zixabiswa ngenxa yokuguquguquka kunye nokuchasana nomswakama kunye namaqondo okushisa aphezulu, okwenza ukuba bafanelekele uluhlu olubanzi lwezicelo. I-latex sealants esekwe emanzini kulula ukuyifaka, iyapeyintwa kwaye inevumba eliphantsi, izenza zilungele iiprojekthi zokutywinwa kwangaphakathi. Ukuqonda iimpawu zezi zitywini kubalulekile ekukhetheni isitywini esifanelekileyo kwiprojekthi ethile.
