Njengoba kunemithethonqubo eqinile yezemvelo kanye nokuqwashisa okuphakeme kokuphepha kwabathengi, ubuchwepheshe be-polypropylene engenalo i-halogen-flame-retardant bube yisinqumo esibalulekile sokulinganisela ukusebenza kwezinto nokuphepha kanye nokuvikelwa kwemvelo. Izinto ezigcina ilangabi zendabuko ze-halogen zikhiqiza amagesi anobuthi futhi agqwalisayo ngesikhathi sokusha, kuyilapho izinto ezigcina ilangabi ze-V0 ezingenalo i-halogen, ezinezakhiwo zazo ezinobungani nemvelo kanye namakhono asebenzayo okugcina ilangabi, zidlala indima ebalulekile ezimbonini ezahlukahlukene.
01 Umongo wobuchwepheshe: Isimiso sokusebenza kanye nohlobo lwe-V0 engenalo i-halogen flame retardant
Ubuchwepheshe obuyinhloko bezinto ezivimbela ilangabi ze-V0 ezingenayo i-halogen busekusebenzeni kwazo okuhlukile okuvimbela ilangabi. Uma zivezwa emazingeni okushisa aphezulu, lezi zinto ezivimbela ilangabi zakha ungqimba lwe-foam olufana noluqinile phezu kwezinto ezibonakalayo. Lolu ngqimba lwe-foam luvikela ngempumelelo ekushiseni nasemoyeni, futhi luvimbela ukukhiqizwa kwentuthu, ngaleyo ndlela lufinyelele isilinganiso se-V-0 esivimbela ilangabi.
Izinto ezivimbela ilangabi ezifakwa yi-nitrogen yizona ezivame kakhulu: ukusebenzisa i-phosphorus ne-nitrogen njengesihluthulelookuvimbela ilangabiIzinto ezisetshenziswayo, ukwengeza cishe u-24%-26% ku-polypropylene kwanele ukufeza indinganiso ye-UL94 V-0 yesampula engu-1.6mm. Lolu hlobo lwesivimbeli somlilo lubonakala ngentuthu ephansi, ubuthi obuphansi, kanye nobungane bemvelo, okuhambisana nesiqondiso semvelo se-EU RoHS kanye nemithethonqubo yasekhaya efanele.
02 Izindawo Zokusebenza: Kusukela ku-elekthronikhi kanye nezinto zikagesi kuya ezingxenyeni zezimoto
Izinto ze-PP ezingenayo i-halogen V0 ezivimbela ilangabi zisetshenziswe kabanzi ezimbonini eziningi, ngezinhlelo zokusebenza ezibalulekile ezifaka:
Emkhakheni wezinto zikagesi kanye nemishini kagesi, lezi zithibi zomlilo zisetshenziswa kabanzi ekusetshenzisweni kwezithibi zomlilo ezindaweni ezahlukene zemishini nezinto ezisetshenziswayo, njengezindawo zokupheka irayisi, izindawo zokufaka ikettle kagesi, izindawo zokuhambisa amanzi, kanye namaphaneli esiqandisi kanye nomshini wokuwasha.
Embonini yezimoto, izithibi zomlilo ze-V0 ezingenayo i-halogen zisetshenziswa ezingxenyeni zesistimu yokupholisa umoya yezimoto, kuma-consoles aphakathi, nakwezinye izingxenye.
Emkhakheni wezinto zokwakha, i-PP engenalo i-halogen evimbela ilangabi isetshenziswa emikhiqizweni efana namashidi namabhodi.
03 Amaphuzu Obuhlungu: Ukuhambisana, Ukuqina Kokushisa, kanye Nezinselele Zokucubungula
Naphezu kwezinzuzo eziningi ze-PP engenalo i-halogen V0 flame-retardant PP, kusenezinselele eziningana zobuchwepheshe ezisetshenziswayo:
Ukuhambisana okungekuhle yinkinga eyinhlokoUkuthathai-ammonium polyphosphate (APP)isibonelo, i-halogen-free flame retardant evame ukusetshenziswa, i-polarity yayo enamandla iholela ekungasebenzi kahle kwe-polypropylene engeyona i-polar, okuthinta kalula izakhiwo zemishini zento uma ingezwa ngobuningi obukhulu.
Ukungazinzi kahle kokushisa kungenye inselele ebalulekile. I-APP iyi-polymer emhlophe ewumpuphu enokumelana nokushisa okubi. Ngaphansi kwezimo zokucubungula ezishisa kakhulu, idlula ku-pyrolysis, ibole ibe izinto ezifana ne-ammonium phosphate, i-metaphosphoric acid, i-ammonia, kanye nomhwamuko wamanzi. Le mikhiqizo yokubola, njenge-metaphosphoric acid, esele ku-resin ingase ivele ngesikhathi sokubumba, inamathele odongeni lwesikhunta noma ku-screw, ithinte kakhulu ukubukeka komkhiqizo kanye nokusebenza kahle kokukhiqiza.
Ukumuncwa komswakama kanye nokufuduka nakho kuyizinkinga ezibalulekile. I-APP inamandla okusebenzisa amanzi kalula, imunca kalula umswakama ovela emoyeni, bese ithuthela endaweni engaphandle, okubangela ukulahlekelwa. Lokhu akugcini nje ngokuphazamisa ukuqina kwezakhiwo ezivimbela ilangabi kodwa futhi kungaholela ekuphazamisekeni kwendawo engaphandle komkhiqizo.
Ukwengeza ngokweqilefuthi kuyinkinga evamile ebhekene ne-PP engenalo i-halogen-flame retardant. Uma kuqhathaniswa ne-halogenated flame retardant yendabuko, izinhlelo ezingenalo i-halogen zivame ukudinga amanani aphezulu okwengeza ukuze kufezwe indinganiso ye-V-0, okubangela izinselele ezimpahleni zemishini kanye nokulawulwa kwezindleko zento.
04 Izixazululo kanye Neziqondiso Zokuthuthukiswa Kwesikhathi Esizayo
Njengoba ibhekene nezinselele zobuchwepheshe ekusetshenzisweni kwe-PP okungenalo i-halogen V0 evimbela ilangabi, imboni isungule izixazululo eziningana ezisebenzayo:
-Ukwelashwa kobuso kanye nokwenza ngcono ukwakheka kuyizindlela ezisebenzayo zokuthuthukisa ukuhambisana.
-Ukuthuthukisa ukulawula inqubo nakho kubalulekile.
-Ukuthuthukisa izinhlelo ezintsha ezivimbela umlilo kuyisisombululo esiyisisekelo.
Isikhathi sokuthunyelwe: Juni-11-2026
