I-polyurethane sealant ingapendiwa ngaphezulu uma selashiwe, ikwenze kube inketho eguquguqukayo yokuvala nokuqeda izinhlelo zokusebenza.

Ukumelana Nesimo Sezulu

Kokubili i-silicone sealant ne-polyurethane sealant inikeza ukumelana nesimo sezulu esihle kakhulu, okubenza bafanelekele izinhlelo zokusebenza zangaphandle. I-Silicone sealant yaziwa ngokumelana kwayo okukhethekile nemisebe ye-UV, i-ozone, nokushintshashintsha kwezinga lokushisa. Ihlala iguquguquka emazingeni okushisa aphezulu futhi ayiqhekeki noma iwonakele ngokuhamba kwesikhathi. I-polyurethane sealant iphinde inikeze ukumelana nesimo sezulu esihle futhi ingamelana nokuchayeka elangeni, imvula, neqhwa. Iyakwazi ukumelana nokuguga futhi igcina izici zayo zokuguquguquka nokunamathela ezimweni ezinzima zemvelo. Uma ukhetha phakathi kwe-silicone sealant ne-polyurethane sealant yezinhlelo zokusebenza zangaphandle, cabangela izimo zezulu ezithile kanye nezidingo zokusebenza zephrojekthi yakho.

Isicelo kanye nesikhathi sokwelashwa

I-Silicone sealant ne-polyurethane sealant inezikhathi ezihlukene zokusetshenziswa nezokwelapha, ezingaba nomthelela ezikhathini zephrojekthi nokusebenza kahle. I-Silicone sealant kulula ukuyisebenzisa ngesibhamu se-caulking futhi ingasetshenziswa kahle ukuze iqede ihlanzekile. Inesikhathi sokwelapha esishesha kakhulu, ngokuvamile isomisa lapho usithinta phakathi nemizuzu engama-30 ukuya ehoreni. Nokho, ukwelapha ngokugcwele kungase kuthathe amahora angaba ngu-24, kuye ngomswakama nezinga lokushisa. I-Polyurethane sealant nayo isetshenziswa ngesibhamu se-caulking futhi ingasetshenziswa ukuze ibukeke kahle. Inesikhathi eside sokwelapha uma kuqhathaniswa ne-silicone sealant, ngokuvamile edinga amahora angu-24 kuya kwangu-48 ukuze yelapheke ngokugcwele. Cabangela ukusetshenziswa kanye nezidingo zesikhathi zephrojekthi yakho lapho ukhetha phakathi kwe-silicone sealant ne-polyurethane sealant.

Ukumelana Kwamakhemikhali

Esinye isici esibalulekile okufanele sicatshangelwe lapho uqhathanisa i-silicone sealant ne-polyurethane sealant yizindawo zabo zokumelana namakhemikhali. I-Silicone sealant imelana namanzi, isikhutha, kanye nezihlanzi eziningi zasendlini, okuyenza ilungele ukusetshenziswa kwekhishi negumbi lokugezela. Kodwa-ke, i-silicone sealant ayinconywa ukuthi isetshenziswe ezindaweni ezivezwe kumakhemikhali anokhahlo noma ama-solvents, njengoba ingase yonakalise ngokuhamba kwesikhathi. I-Polyurethane sealant inikeza ukumelana okuhle kwamakhemikhali kumafutha, uwoyela, nezincibilikisi, okwenza kube ukukhetha okuthandwayo kwezicelo zezimoto nezimboni. Iphinde imelane namanzi kanye nesikhutha, okuyenza ifanelekele indawo yangaphandle nemanzi. Linganisa izidingo zokumelana namakhemikhali ephrojekthi yakho ukuze unqume isitywini esifaneleka kakhulu sezidingo zakho.

Sengiphetha, kokubili i-silicone sealant ne-polyurethane sealant inamandla nobuthakathaka babo, okwenza kube lula ukusetshenziswa okuhlukile. I-Silicone sealant iyi-sealant eguquguqukayo futhi ekwazi ukumelana nesimo sezulu enikeza ukunamathela okuhle nokuvumelana nezimo. Ilungele ukusetshenziswa kwangaphakathi nangaphandle lapho ukuchayeka emisebeni ye-UV kanye nezinga lokushisa elidlulele kukhathazeka. I-polyurethane sealant iyisici esiqinile futhi esihlala isikhathi eside esihlinzeka ngokunamathela okuphezulu nokumelana namakhemikhali. Ilungele izinhlelo zokusebenza zokuvala ezisebenza kahle embonini yokwakha, yezimoto, nezasolwandle. Cabangela izidingo ezithile zephrojekthi yakho, njengokunamathela, ukuguquguquka, ukumelana nesimo sezulu, isicelo, isikhathi sokwelapha, nokumelana namakhemikhali, ukuze unqume ukuthi i-silicone sealant noma i-polyurethane sealant iyisinqumo esifanele yini kuwe.
