Mu gihe amabwiriza ya EU REACH n'amahame mpuzamahanga agenga ibidukikije bikomeje gukazwa, abakora irangi rigabanya inkongi bahura n'imbogamizi zikomeye zo kubahiriza amategeko. Kubuza halogen, ibyuma biremereye na PBDE bituma imiti gakondo idakoreshwa ku isoko, mu gihe ikoreshwa mu nganda no mu baturage rikomeje kuba rinini. Ammonium polyphosphate (APP) ni igisubizo cy'ingenzi cyo kuringaniza iyubahirizwa ry'amategeko n'imikorere, bitewe n'imiterere yayo ihoraho kandi idafite halogen.
REACH ibuza imiti yangiza irenga 2000, harimo n’ibintu bigabanya umuriro bya halogenated fire retardants mu irangi gakondo. PBB na PBDE birabujijwe kubera ko bihoraho kandi bifite uburozi, aho inganda zitubahiriza amategeko zishobora gufungwa, gucibwa amande cyangwa kurekurwa ku isoko.
Uretse kubahiriza amategeko, ibintu bigabanya umuriro bifite halogenated fire retard bisohora imyuka ihumanya iyo byatwitswe kandi bigahuza nabi na epoxy/acrylic resins, bigatera gutandukana kw'amazi no kugabanuka k'ubufatanye bw'amazi—bigatuma abantu bashaka ubundi buryo bwo kubyaza ibidukikije.
Kubera ko ari ikintu kidakoresha umuriro kitagira halogen, APP yujuje ibisabwa na REACH. Igice cyayo cy'ingenzi (NH4)n+2PnO3n+1 nta bintu bibujijwe kirimo kandi cyanditswe na REACH. Ifite imiterere y'umweru ya crystalline (aho ishonga ni 240-280℃, ubushyuhe bwo kubora ni >300℃), igumana ubuziranenge mu gihe cyo gushonga.
APP igabanya ubushyuhe bw'umuriro binyuze mu gukora karuboni ituruka mu nda: ubushyuhe bwinshi butuma habaho irekurwa rya aside polyphosphoric ya ammonia na polyphosphoric, bigatuma habaho urwego rukingira ogisijeni. Bitandukanye n'uburyo bwa halogenated, ntabwo itanga imyuka ihumanya, ijyanye n'imiterere y'icyatsi kibisi.
Gutunganya imiterere y'ibimera bifungura ubushobozi bwose bwa APP. Ku bijyanye n'ibirahure bishingiye ku mazi, APP yo mu rwego rw'inganda (n≥1000 polymerization degree) ituma bishonga kandi bigakora neza, bikarinda imvura kugwa. Ku bijyanye n'ibirahure bishingiye ku bimera, guhindura igikoresho cyo guhuza silane byongera ubushobozi bwo gutandukana no gufatana.
APP ihuza neza na melamine na pentaerythritol kugira ngo ikoreshwe mu buryo bw'ingufu. Ibizamini by'inganda byemeza ko irangi rifite 25-30% APP (igice kinini) rihuye n'urwego rwa GB/T 8624-2012 B1 rudakoresha umuriro kandi rufite urwego rwa 1, bityo bigatuma ikoreshwa ryaryo rirushaho kuba ryiza.
Mu gihe cyo kuvugurura ibidukikije, APP ituma inganda zikora irangi ridakoresha umuriro zihinduka. Imiterere yayo idafite halogen, ikurikiza amategeko kandi ihamye ikemura ibibazo bya REACH kandi igashyigikira umutekano w'inkongi—kumenya gukoresha APP neza ni ingenzi ku bakinnyi kugira ngo bahiganwe.
