Ama-sealants anezinto ezisemqoka ezisetshenziswa ngaphesheya kwezakhiwo zezinkampani zamaphrojekthi namaphrojekthi we-DIY. Bavala izikhala, bavikele i-Ingress, futhi baqinisekise isikhathi eside ezinkingeni nasemihlanganweni emikhulu. Ukukhetha i-sealant efanele kubaluleke kakhulu ekufezekiseni imiphumela efanele. Le ndatshana ihlinzeka ngokuqhathanisa okujulile kwezinhlobo ezimbili ezivame ukubekelwa phansi:polyurethane sealantkanye ne-silicone sealant, kukunikeza amandla okwenza izinqumo ezinolwazi ngezidingo zakho ezithile.
Ukuqonda ama-sealants: izisekelo
Ayini ama-sealants futhi kungani ubadinga?
Ama-sealants yizinto ezibonakalayo ezenzelwe ukugcwalisa izikhala futhi adale izithiyo ezingenamsebenzi. Zivimba ukudlula koketshezi, amagesi, futhi nezinhlaziyi, ukuvikela ukulimala komswakama, ukugqwala, nokuwohloka kwesakhiwo. Ukusuka ekani uphawu nasezicabheni zokubopha izingxenye zezimoto, ama-sealants adlala indima ebalulekile ekuthuthukiseni ukusebenza futhi anwebe isikhathi sokuphila kwemikhiqizo ehlukahlukene. Ukusebenza kwabo okuhlukahlukene kubenza babaluleke ekwakheni, izimoto, zasolwandle, kanye nezicelo ze-aerospace.
Ukubuka konke okufushane kwezinhlobo ze-sealant
Umhlaba wama-sealants uhlanganisa uhla oluhlukile lwama-makhi, ngayinye inezimpawu ezihlukile. Ama-acrylics, ama-butyls, ama-polysulfides, ama-epoxies, kanye nokugxila kwale ngxoxo - ama-polyurethanes nama-silicones - amele nje ingxenye yezinketho ezitholakalayo. Ukuqonda ama-nuances ohlobo ngalunye kubalulekile ekukhetheni i-sealant ekahle yohlelo lokusebenza olunikeziwe.
I-Polyurethane Sealants(Pu Sealant): Izakhiwo kanye Nezicelo
