Zakuthupi ndi Zamankhwala Ammonium polyphosphate atha kugawidwa m'mitundu itatu kutengera digiri yake ya polymerization: otsika polima, apakati polima, ndi ma polima apamwamba. Kuchuluka kwa ma polymerization, kumachepetsa kusungunuka kwamadzi. Malinga ndi kapangidwe kake, imatha kugawidwa mumitundu ya crystalline ndi amorphous. Crystalline ammonium polyphosphate ndi wosasungunuka m'madzi komanso unyolo wautali wa polyphosphate. Pali mitundu isanu kuchokera ku I mpaka V mtundu.
Gwiritsani ntchito Inorganic additive flame retardant, yomwe imagwiritsidwa ntchito popanga zokutira zoziziritsa moto, mapulasitiki oletsa malawi ndi zinthu za rabala zoletsa malawi, ndi zina zambiri.
Amagwiritsidwa ntchito kwambiri popangira zokutira zoziziritsa moto komanso ma resins a thermosetting (monga thovu lolimba la polyurethane, UP resin, epoxy resin, ndi zina zambiri), ndipo amathanso kugwiritsidwa ntchito popanga malawi a fiber, nkhuni ndi mphira. Popeza APP ili ndi kulemera kwakukulu kwa mamolekyu (n> 1000) komanso kukhazikika kwakukulu, ingagwiritsidwenso ntchito ngati chogwiritsira ntchito kwambiri cha intumescent flame retardant thermoplastics, makamaka PP mpaka UL 94-Vo popanga zida zamagetsi.

Mawu Oyamba

Ammonium polyphosphate (PAAP mwachidule) ndi polima wopanda organic wokhala ndi mphamvu yoletsa moto komanso yosagwira moto. Mapangidwe ake a molekyulu amakhala ndi ma polima a phosphate ndi ammonium ions.

 

Ammonium polyphosphate imagwiritsidwa ntchito kwambiri muzoletsa moto, zotchingira ndi zokutira zoletsa moto. Ikhoza kupititsa patsogolo ntchito yoletsa moto wazinthu, kuchedwetsa kuyaka, kulepheretsa kufalikira kwa malawi, komanso kuchepetsa kutulutsa mpweya woipa ndi utsi.

 

Njira yopangira ammonium polyphosphate nthawi zambiri imaphatikizapo zomwe phosphoric acid ndi ammonium salt. Panthawiyi, mgwirizano wa mankhwala pakati pa phosphate ndi ammonium ions amapangidwa, kupanga ma polima okhala ndi mayunitsi angapo a phosphate ndi ammonium ion.

 

Chidziwitso cha Chitetezo: Ammonium polyphosphate ndi yotetezeka ngati ikugwiritsidwa ntchito komanso kusungidwa bwino. Pewani kulowetsa fumbi la ammonium polyphosphate chifukwa lingayambitse vuto la kupuma. Mukamagwira ammonium polyphosphate, tsatirani mosamalitsa njira zoyendetsera chitetezo ndikusunga bwino ndikutaya pawiri.
