Abubuwan Jiki da Sinadarai Ammonium polyphosphate za a iya raba uku iri dangane da matakin na polymerization: low polymer, matsakaici polymer, kuma high polymer. Matsayi mafi girma na polymerization, ƙananan ƙarancin ruwa. Bisa ga tsarinsa, ana iya raba shi zuwa nau'in crystalline da amorphous. Crystalline ammonium polyphosphate shine ruwa marar narkewa kuma polyphosphate mai tsayi. Akwai bambance-bambancen guda biyar daga nau'in I zuwa V.
Amfani Inorganic additive harshen wuta retardant, amfani da kerarre na harshen wuta retardant coatings, harshen wuta retardant robobi da harshen wuta retardant kayayyakin roba, da dai sauransu.
Ana amfani dashi da yawa a cikin rufin wuta na intumescent da resins na thermosetting (kamar polyurethane m kumfa, guduro UP, guduro epoxy, da dai sauransu), kuma ana iya amfani dashi don hana wuta na fiber, itace da samfuran roba. Tun da APP yana da babban nauyin kwayoyin halitta (n> 1000) da babban kwanciyar hankali, ana iya amfani dashi azaman babban kayan aiki na intumescent flame retardant thermoplastics, musamman a cikin PP har zuwa UL 94-Vo don kera sassan lantarki.

Ammonium polyphosphate (PAAP a takaice) polymer inorganic ne tare da kaddarorin da ke jurewa wuta. Tsarin kwayoyinsa ya ƙunshi polymers na phosphate da ammonium ions.

 

Ammonium polyphosphate ana amfani da shi sosai a cikin masu hana wuta, kayan da ba su da ƙarfi da kuma abubuwan da ke hana wuta. Yana iya inganta ingantaccen aikin hana wuta na kayan aiki, jinkirta tsarin konewa, hana yaduwar wuta, da rage sakin iskar gas da hayaki masu cutarwa.

 

Hanyar shirya ammonium polyphosphate yawanci ya ƙunshi amsawar phosphoric acid da ammonium salts. A lokacin da ake amsawa, an samar da haɗin gwiwar sinadarai tsakanin phosphate da ammonium ions, suna samar da polymers tare da raka'o'in phosphate da ammonium ion.

 

Bayanin Tsaro: Ammonium polyphosphate ba shi da lafiya a ƙarƙashin amfani na yau da kullun da yanayin ajiya. Ka guji shakar ammonium polyphosphate ƙura domin yana iya haifar da matsalolin numfashi. Lokacin sarrafa ammonium polyphosphate, bi ƙaƙƙarfan hanyoyin aminci masu dacewa kuma adanawa da zubar da fili yadda yakamata.
