Ubucucike 1.74 [kuri 20 ℃]
Umwuka 0.076Pa kuri 20 ℃
Kugaragara Ifu yera
Imiterere y'Ububiko −20 ° C.
Ibintu bifatika na shimi Ammonium polyphosphate irashobora kugabanywamo ubwoko butatu ukurikije urugero rwa polymerisation: polymer nkeya, polymer yo hagati, na polymer ndende. Urwego rwo hejuru rwa polymerisiyonike, niko amazi agabanuka. Ukurikije imiterere yabyo, irashobora kugabanywamo ubwoko bwa kristalline na amorphous. Crystalline ammonium polyphosphate ni amazi adashonga hamwe na polifosifate ndende. Hariho ibintu bitanu kuva I kugeza kuri V.
Koresha Inorganic additive flame retardant, ikoreshwa mugukora ibicanwa bya flame retardant, plastike ya flame retardant hamwe nibikoresho bya reberi ya flame retardant, nibindi.
Ikoreshwa cyane cyane mubyuma byangiza umuriro hamwe nubushuhe bwa termosetting (nka polyurethane rigid foam, UP resin, epoxy resin, nibindi), kandi birashobora no gukoreshwa mumashanyarazi yibikoresho bya fibre, ibiti nibicuruzwa bya reberi. Kubera ko APP ifite uburemere buke bwa molekile (n> 1000) hamwe no guhagarara neza, irashobora kandi gukoreshwa nkibintu byingenzi bigize intumecent flame retardant thermoplastique, cyane cyane muri PP kugeza UL 94-Vo kugirango ikore ibice bya elegitoroniki.

Intangiriro

Ammonium polyphosphate (PAAP mu magambo ahinnye) ni polymer idasanzwe kandi ifite imiti irinda umuriro kandi irwanya umuriro. Imiterere ya molekuline igizwe na polymers ya fosifate na ioni ya amonium.

 

Ammonium polyphosphate ikoreshwa cyane mubirinda umuriro, ibikoresho bivunika no gutwika umuriro. Irashobora kunoza neza imikorere yumuriro wibikoresho, gutinza inzira yo gutwika, kubuza ikwirakwizwa ryumuriro, no kugabanya irekurwa ryimyuka yumwotsi numwotsi.

 

Uburyo bwo gutegura ammonium polyphosifate mubusanzwe burimo reaction ya acide fosifori hamwe nu munyu wa amonium. Mugihe cyo kubyitwaramo, havuka imiyoboro ya chimique hagati ya fosifate na ioni ya amonium, ikora polymer hamwe na fosifate nyinshi hamwe na ion amonium.

 

Amakuru yumutekano: Ammonium polyphosphate ifite umutekano muke mugukoresha bisanzwe no kubika. Irinde guhumeka umukungugu wa amonium polyphosifate kuko ushobora gutera ibibazo byubuhumekero. Mugihe ukoresha ammonium polyphosphate, kurikiza byimazeyo uburyo bukoreshwa mubikorwa byumutekano kandi ubike neza kandi ujugunye uruganda.
