Ukwenza ama-plastiki abushelelezi amalangabi, ngokuvamile kuyadingeka ukwengeza ama-flame retardants. Ama-flame retardants ayizithasiselo ezinganciphisa ukusebenza kokuvutha kwamapulasitiki. Bashintsha inqubo yokushiswa kwamapulasitiki, banciphise ukusakazeka kwamalangabi, futhi banciphise inani lokushisa elikhishwayo, ngaleyo ndlela bathole umphumela wokunqanda ilangabi. Okulandelayo kuzokwethula izindlela ezijwayelekile zokwenza amapulasitiki angabusheki amalangabi.
Ukwengeza ama-inorganic flame retardants: I-Inorganic flame retardants ibhekisela ezintweni ezibuyisela amalangabi ezakhiwe ngezinto ezingaphili njengezinsimbi, ama-oxide ensimbi, nosawoti wensimbi. I-inorganic flame retardants evamile ihlanganisa i-aluminium hydroxide, i-magnesium oxide, i-zinc oxide, njll. Lezi zinciphisi ze-inorganic flame zingabola emazingeni okushisa aphezulu ukuze zikhiphe umhwamuko wamanzi noma ama-oxide, zimunce ukushisa, zenze ungqimba oluvikelayo, futhi zivimbele ukusabalala komoyampilo nokushisa, ngaleyo ndlela zithole umphumela wokunqanda ilangabi.
Ukwengeza ama-organic flame retardants: I-Organic flame retardants ibhekisela ezintweni ezibuyisela amalangabi ezakhiwe ngezinto eziphilayo eziqukethe izakhi ezifana ne-nitrogen, i-phosphorus, ne-bromine. Ama-organic flame retardants avamile ahlanganisa i-ammonium polyphosphate, i-brominated flame retardants, njll. Lezi zinto ezibuyisela amalangabi eziphilayo zingabola emazingeni okushisa aphezulu ukuze zikhulule i-nitrogen, i-phosphorus oxides noma ama-bromides, zenze ungqimba lwekhabhoni, futhi zivimbele ukusabalala komoyampilo nokushisa, ngaleyo ndlela zithole umphumela we-flame retardant.
Ukwelashwa okungaphezulu: Ngokwenza ukwelashwa okukhethekile endaweni yepulasitiki, kwakhiwa ifilimu ye-flame retardant ukuvimbela ukusabalala komoya-mpilo nokushisa, ngaleyo ndlela kuzuzwe umphumela we-flame retardant. Izindlela ezijwayelekile zokwelashwa kwendawo zifaka ukufutha ama-flame retardants, i-vacuum coating, njll.
Idizayini yesakhiwo: Ngokushintsha ukwakheka kwamangqamuzana epulasitiki, inezindawo zayo zokunqanda ilangabi. Isibonelo, ngokwethula amaqembu asebenzayo aqukethe i-nitrogen, i-phosphorus nezinye izakhi, ukuhlelwa kweketango lamangqamuzana kuguqulwa ukuze kuthuthukiswe izakhiwo ze-flame retardant zepulasitiki.
Ekusetshenzisweni okungokoqobo, izindlela ezifanele zokunqanda amalangabi kanye nezinqamuleli zomlilo zivame ukukhethwa ngokuya ngokusetshenziswa okukhethekile kanye nezidingo zepulasitiki ukuze kuqinisekiswe ukuthi imikhiqizo yepulasitiki inezindawo ezinhle zokunqanda ilangabi. Ngesikhathi esifanayo, izici ezifana nokusebenza kwemvelo kanye nobuthi be-flame retardant kudingeka kucatshangelwe ukuze kuqinisekiswe ukuphepha nokuvikelwa kwemvelo kwemikhiqizo yepulasitiki.
Ngokuvamile, ama-flame retardants avame ukungezwa ukuze enze ipulasitiki ibe nezindawo zokunqanda amalangabi, futhi izakhiwo zokuvutha zepulasitiki zishintshwa yi-inorganic flame retardants, i-organic flame retardants, ukwelashwa kwendawo, ukuklama kwesakhiwo nezinye izindlela zokufeza umphumela wokunqanda ilangabi. Lapho kukhethwa izindlela zokunqanda amalangabi nezinto ezibuyisela amalangabi, izici ezifana nokusetshenziswa, ukusebenza kwemvelo, nokuphepha kwepulasitiki kudingeka kubhekwe kabanzi ukuze kuqinisekiswe ukuthi imikhiqizo yepulasitiki inezindawo ezinhle zokunqanda ilangabi.
