Ukuqulunqwa komnyango kunye nefestile yefestile

Njengenxalenye ebalulekileyo yemathiriyeli yokutywina yokwakha, ukusebenza kweengcango kunye nezitywini zefestile kuchaphazela ngokuthe ngqo ukungangeni komoya, ukungangeni kwamanzi, kunye nokuqina kweengcango neefestile. Ukuqulunqwa kwenzululwazi kunye nengqiqo kuqinisekisa ukuba i-sealant inokunamathela okugqwesileyo, ukuqina, kunye nokumelana nemozulu, ukuhlangabezana neemfuno zeendawo ezahlukeneyo.

 

Amacandelo aphambili omnyango kunye nezitywina zefestile ziquka i-binder, fillers, plasticizers, agent agents, kunye nezongezo. Isibophelelo, icandelo elingundoqo lesitywina, ngokuqhelekileyo lisebenzisa iipholima ezifana ne-silicone, i-polyurethane, okanye i-acrylates, kwaye imisela iimpawu ezisisiseko zesitywina. Izibophelelo ze-silicone zibonelela ngokugqwesileyo kokumelana nobushushu obuphezulu kunye nobuphantsi kunye nokumelana nemozulu, kubenza bafanelekele iimeko ezingqongileyo ezigqithisileyo. Izibophelelo zePolyurethane zibonelela ngokuncamathela okomeleleyo kunye nokunwebeka, okuzenza zilungele ukutywinwa okuguquguqukayo. Izibophelelo ze-Acrylate zome ngokukhawuleza kwaye zifanelekile kumnyango wangaphakathi kunye nokutywinwa kwefestile.

Iifayili, ezifana ne-calcium carbonate, i-carbon black, okanye i-silica, zisetyenziselwa ukuphucula iimpawu zomzimba ze-sealant, ukuphucula ubulukhuni, ukuxhathisa i-abrasion, kunye nokuxhatshazwa kwe-shrinkage. IiPlastiki (ezifana neephthalates) ziphucula ukuguquguquka kwesitywina, ukunqanda ukuba ingaqhekeki ngexesha lokuguquguquka kobushushu. Iiarhente zokunyanga zikhuthaza umnqamlezo{2}}ukudibanisa ukusabela kwizitywini, ukuziguqula ukusuka kulwelo ukuya kwimeko eqinileyo. Iindlela zokunyanga eziqhelekileyo ziquka ukunyanga ukufuma (umzekelo, ii-silicone sealants) kunye nokunyangwa kweekhemikhali (umz., i-polyurethane sealants).

Ukongeza, izongezo ezinje nge-antioxidants, i-UV absorbers, kunye ne-thixotropic agents zinokunyusa ngakumbi ukuchasana nokuguga kwe-sealant kunye nokusebenza. Iijenti ze Thixotropic zithintela i-sealant ukuba isebenze xa isetyenziswe kwiindawo ezithe nkqo, iqinisekisa ukuzaliswa okufanayo.

Isishwankathelo, ukuqulunqwa kweengcango kunye neefestile ze-sealants kufuna ukuqwalaselwa ngokubanzi kohlobo lwezinto ezisisiseko, umlinganiselo wokuzalisa, kunye nokukhethwa okongeziweyo ukuze kuqinisekiswe ukunamathela okugqwesileyo, ukuqina, kunye nokuqina, ukuphucula ngokufanelekileyo ukutywinwa kokusebenza kunye nobomi benkonzo yeengcango kunye neefestile.
