IiPropati zoMzimba kunye nezeMichiza I-Ammonium polyphosphate inokohlulwa ibe ziindidi ezintathu ngokwenqanaba lepolymerization: i-polymer ephantsi, i-polymer ephakathi, kunye ne-polymer ephezulu. Ukuphakama kweqondo lepolymerization, encinci ukunyibilika kwamanzi. Ngokwesakhiwo sayo, inokwahlulwa ibe ziintlobo zekristale kunye ne-amorphous. Icrystalline ammonium polyphosphate ngamanzi anganyibilikiyo kunye nekhonkco elide lepolyphosphate. Kukho iintlobo ezintlanu ukusuka ku-I ukuya ku-V uhlobo.
Sebenzisa I-Inorganic additive additive retardant, esetyenziswa ekwenzeni iileya ezibuyiswa ngamadangatya, iiplastiki ezibuyiswa ngamadangatye kunye neemveliso zerabha ezibuyiswa ngumlilo, njl.
Isetyenziswa ikakhulu kwi intumescent retardant retardant yomlilo kunye resins thermosetting (ezifana polyurethane ugwebu eqinileyo, UP resin, epoxy resin, njl.), kwaye ingasetyenziselwa idangatye retardant ifayibha, iinkuni kunye neemveliso zerabha. Ekubeni i-APP inobunzima obuphezulu be-molecular (n> 1000) kunye nokuzinza okuphezulu, inokusetyenziswa njengeyona nto isebenzayo ye-intumescent flame retardant thermoplastics, ngakumbi kwi-PP ukuya kwi-UL 94-Vo yokwenziwa kwezixhobo ze-elektroniki.

Intshayelelo

I-Ammonium polyphosphate (i-PAAP ngokufutshane) yipolymer engaphiliyo eneempawu zokubuyiswa komlilo kunye nezinto ezikwaziyo ukumelana nomlilo. Ubume bayo bemolekyuli buqukethe iipolymers zephosphate kunye ne-ammonium ion.

 

I-Ammonium polyphosphate isetyenziswa kakhulu kwi-flame retardants, izinto eziphikisayo kunye neengubo ezithintela umlilo. Inokuphucula ngokufanelekileyo ukusebenza kwe-flame retardant yezinto, ukulibazisa inkqubo yokutsha, ukuvimbela ukusasazeka kwamadangatye, kunye nokunciphisa ukukhutshwa kweegesi ezinobungozi kunye nomsi.

 

Indlela yokulungiselela i-ammonium polyphosphate ngokuqhelekileyo ibandakanya ukusabela kwe-asidi ye-phosphoric kunye neetyuwa ze-ammonium. Ngethuba lokuphendula, iibhondi zeekhemikhali phakathi kwe-phosphate kunye ne-ammonium ions zenziwe, zenza iipolymers kunye neeyunithi ezininzi ze-phosphate kunye ne-ammonium ion.

 

Ulwazi ngoKhuseleko: I-Ammonium polyphosphate ikhuselekile ngokwentelekiso phantsi kokusetyenziswa okuqhelekileyo kunye neemeko zokugcinwa. Kuphephe ukuphefumla uthuli lwe-ammonium polyphosphate njengoko kunokubangela iingxaki zokuphefumla. Xa uphatha i-ammonium polyphosphate, landela ngokungqongqo iinkqubo zokusebenza ezifanelekileyo zokhuseleko kwaye ugcine ngokufanelekileyo kwaye ulahle i-compound.
