I-halogen-free flame retardants idlala indima ebalulekile emkhakheni wezokuthutha.

I-halogen-free flame retardants idlala indima ebalulekile emkhakheni wezokuthutha. Njengoba ukwakhiwa kwezimoto kuqhubeka nokuthuthuka futhi izinto zepulasitiki zisetshenziswa kabanzi, izakhiwo ezivimba amalangabi ziba yinto ebalulekile. I-halogen-free flame retardant iyinhlanganisela engaqukethe ama-elementi e-halogen njenge-chlorine ne-bromine futhi inomphumela omuhle kakhulu we-flame retardant. Ezokuthutha, izinto zepulasitiki zisetshenziswa kakhulu, njengezesekeli zangaphakathi zemoto, ama-casings edivayisi ye-elekthronikhi, njll. Kodwa-ke, amapulasitiki avame ukuba nezakhiwo ezimbi ezivuthayo futhi angabangela kalula izingozi zomlilo. Ngakho-ke, ama-flame retardants adinga ukwengezwa ukuze kuthuthukiswe izakhiwo ze-flame retardant zamapulasitiki futhi kuqinisekiswe ukuphepha kwethrafikhi. Ukugcizelelwa okukhethekile kufanele kubekwe ku-ammonium polyphosphate (APP). Njengesinqamuleli somlilo esingenawo i-halogen esivame ukusetshenziswa, i-APP idlala indima ebalulekile ekubambezelekeni kwelangabi lepulasitiki. I-APP ingasabela ngokwekhemikhali nge-substrate yepulasitiki ukuze yakhe isendlalelo esiminyene se-carbonization, esihlukanisa ngempumelelo ukudluliswa komoyampilo nokushisa, yehlise izinga lokusha futhi ivimbele ukusabalala komlilo. Ngesikhathi esifanayo, izinto ezifana ne-phosphoric acid kanye nomhwamuko wamanzi okhishwe i-APP nawo angavimbela ukusha futhi athuthukise izakhiwo zepulasitiki ezibamba ilangabi. Ngokungeza ama-flame retardants angenayo i-halogen njenge-ammonium polyphosphate, izinto zepulasitiki ezimotweni zingathola izakhiwo ezinhle zokuvimbela amalangabi futhi zinciphise ukuvela kwezingozi zomlilo. Ukuthuthukisa ukuphepha nokuthembeka kwezokuthutha. Njengoba izidingo zokuvikelwa kwemvelo zanda, amathuba okufaka isicelo se-halogen-free flame retardants azokhula.
