Yini Eyenza I-PU Foam Evimbela Umlilo Ifaneleke Ezinhlelweni Zokuphepha?

Ezweni lanamuhla, ukuphepha kubaluleke kakhulu kuzo zonke izimboni ezahlukene. Enye into eye yathola ukunakwa okukhulu ekusetshenzisweni kwayo kokuphepha yi-fire retardant polyurethane (PU) foam. Le foam eguquguqukayo isetshenziswa kabanzi ezinhlotsheni ezahlukene zezicelo, lapho izakhiwo zayo ezihlukile zingagcini nje ngokuqinisekisa ubuqotho besakhiwo kodwa futhi ziqinisekisa ukuphepha okuthuthukisiwe ezingozini zomlilo. Lesi sihloko sizohlola izakhiwo ze-PU foam evimbela umlilo, ukusetshenziswa kwayo ezindaweni ezibalulekile zokuphepha, kanye nezinzuzo ezinikezayo ngaphezu kwezinto zendabuko.

Izakhiwo ze-PU Foam evimbela umlilo

Ukwakheka Kwamakhemikhali

I-PU foam evimbela umlilo yakhelwe ngezithasiselo ezithile namakhemikhali athuthukisa izakhiwo zayo ezingashisi. Lezi zithasiselo zifaka phakathi izinto ezibangela ukusha, izinto ezivimbela umlilo, nezinye izinto ezifaka isandla ekuphepheni kwayo.

Ama-Intumescent Ejenti

Ama-intumescent agents angenye yezingxenye ezibalulekile ku-PU foam evimbela umlilo. Uma evezwa emazingeni okushisa aphezulu, la ma-agents akha ungqimba lwe-char olunweba futhi luvikele i-foam, luvimbele ukusabalala komlilo futhi lunciphise ukusha kwalo.

Izithibi Zomlilo

Izinto ezivimbela ilangabi zingenye into ebalulekile. Zisebenza ngokumunca ukushisa, ukuvimbela ukusha, noma ukuphula inqubo yokusha. Izinto ezivimbela ilangabi ezivamile zifaka phakathi izinto ezisekelwe ku-phosphorus, izinto ezisuselwe ku-silicone, kanye nezinto ezixutshwe ne-brominated.

Amanye Amakhemikhali Abalulekile

Amanye amakhemikhali afana nama-blowing agents, ama-cross-linking agents, kanye nama-stabilizers nawo ayengezwa ukuthuthukisa ukuqina nokusebenza kwe-foam. Lawa makhemikhali aqinisekisa ukuthi i-foam igcina ubuqotho bayo ngaphansi kwamazinga okushisa aphezulu futhi inikeza izinzuzo zokuphepha zesikhathi eside.
