Umgangatho ophezuluizitywini zokwakhaidlala indima ebalulekileyo ekwakheni ugcino kunye nobomi obude. Phakathi kweentlobo ezahlukeneyo zezitywini zokwakha ezikhoyo, ii-polyurethane sealants, ezikwabizwa ngokuba zii-PU sealants, zigqame njengokhetho oludumileyo ngenxa yeempawu zazo ezikhethekileyo kunye nokuguquguquka.
Izitywini zokwakha zibalulekile ekukhuseleni izakhiwo kwizinto zokusingqongileyo ezifana namanzi, umoya nothuli. Benza umqobo othintela umswakama ukuba ungangeni kwisakhiwo, nto leyo inokukhokelela kumonakalo wesakhiwo kunye nokukhula kokungunda. Ukongeza, izitywina zinceda ekuphuculeni ukusebenza kakuhle kwamandla ngokuvala izikhewu kunye neentanda, ngaloo ndlela kuncitshiswe ukuvuza komoya kunye nokulahleka kobushushu.
Xa kuziwa kwii-sealants zokwakha, ii-polyurethane sealants zithathwa kakhulu ngenxa yokuqina kwazo kunye nokuguquguquka. Ii-PU sealants zaziwa ngokuncamathela kwazo kuluhlu olubanzi lwezixhobo, kubandakanya ikhonkrithi, umthi, intsimbi kunye neplastiki. Oku kuguquguquka kubenza bafaneleke kwizicelo ezahlukeneyo, ukusuka kwiindawo zokutywinwa kunye nezikhewu kwiifestile kunye neengcango zokugcwalisa iintanda kwizakhiwo zekhonkrithi.
Ukusebenzisa i-polyurethane sealants yomgangatho ophezulu kubalulekile ekuqinisekiseni ukusebenza kakuhle kokugcinwa kwesakhiwo. Izitywini ezingaphantsi zisenokwehla ekuhambeni kwexesha, nto leyo ekhokelela kwiintanda nezikhewu ezibeka esichengeni isidima sesakhiwo. Izitywini ze-PU ezikumgangatho ophezulu, kwelinye icala, zibonelela ngokhuseleko oluhlala ixesha elide kwaye zinokumelana nemozulu embi, ukuvezwa kwe-UV, kunye nokutshintsha kobushushu.
Ukongeza kwiipropati zabo zokukhusela, i-polyurethane sealants inegalelo kwi-aesthetics jikelele yesakhiwo. Zifumaneka ngemibala eyahlukahlukeneyo kwaye zinokupeyintwa ngokulula ukuze zihambelane nomphandle wesakhiwo, zibonelela ngokugqibeleleyo nokupholisiweyo.Ukusetyenziswa ngokufanelekileyo kwezitywina zokwakha, ngokukodwa ii-polyurethane sealants, kufuna ingqalelo kwiinkcukacha kunye nokuthotyelwa kwemigaqo yomenzi. Kubalulekile ukulungisa umgangatho ngokufanelekileyo kwaye usebenzise i-sealant ngokulinganayo ukuqinisekisa ukusebenza okuphezulu.
Ukuqukumbela, ukubaluleka kokusebenzisa izitywini zokwakha ezikumgangatho ophezulu, ngokukodwa ii-polyurethane sealants, azikwazi ukugqithiswa. Ezi zitywina ziyimfuneko ekugcinweni kwesakhiwo, ukunika ukhuseleko kumswakama, ukuphucula ukusebenza kakuhle kwamandla, kunye nokuphucula ukubonakala ngokubanzi kwesakhiwo. Utyalo-mali kwii-premium sealants ze-PU sisigqibo esilumkileyo sokuqinisekisa ukuqina kwexesha elide kunye nokusebenza kwezakhiwo.
