I-Ammonium polyphosphate CAS 68333-79-9 Isithombe Esifakiwe
  • I-Ammonium polyphosphate CAS 68333-79-9 1

I-Ammonium polyphosphate CAS 68333-79-9

Isakhiwo Samakhemikhali:

I-Molecular Formula I-H12N3O4P
I-Molar Mass 149.086741
Ukuminyana 1.74 [ku-20℃]
I-Vapor Presure 0.076Pa ku-20℃
Ukubukeka Impushana emhlophe

Izakhiwo Zomzimba Nezamakhemikhali I-Ammonium polyphosphate ingahlukaniswa ngezinhlobo ezintathu ngokuya ngezinga layo le-polymerization: i-polymer ephansi, i-polymer ephakathi, ne-polymer ephezulu. Uma izinga le-polymerization liphakeme, kuncane ukuncibilika kwamanzi. Ngokusho kwesakhiwo sayo, ingahlukaniswa ngezinhlobo ze-crystalline ne-amorphous. I-Crystalline ammonium polyphosphate ayincibiliki emanzini futhi i-polyphosphate enamaketanga amade. Kunezinhlobonhlobo ezinhlanu ukusuka ohlotsheni luka-I kuye ku-V.
Sebenzisa I-Inorganic additive retardant ye-flame retardant, esetshenziswa ekwakheni amalangabi abushelelezi amalangabi, amapulasitiki abushela amalangabi kanye nemikhiqizo yenjoloba ebuyisela amalangabi, njll.
Isetshenziswa kakhulu emigqonyeni ye-intumescent retardant kanye nezinhlaka ze-thermosetting (njengegwebu eliqinile le-polyurethane, i-UP resin, i-epoxy resin, njll.), futhi ingasetshenziselwa ukunqanda ilangabi le-fiber, izinkuni kanye nemikhiqizo yenjoloba. Njengoba i-APP inesisindo samangqamuzana aphezulu (n>1000) kanye nokuzinza okuphezulu, ingasetshenziswa futhi njengesithako esiyinhloko esisebenzayo se-intumescent flame retardant thermoplastics, ikakhulukazi ku-PP kufika ku-UL 94-Vo ekwenzeni izingxenye ze-electronic.

Isingeniso

I-Ammonium polyphosphate (i-PAAP ngamafuphi) i-polymer engaphili ekwazi ukumelana namalangabi futhi imelana nomlilo. Isakhiwo sayo samangqamuzana siqukethe ama-polymers we-phosphate ne-ammonium ions.

 

I-Ammonium polyphosphate isetshenziswa kabanzi kuma-flame retardants, izinto eziphikisayo kanye nezingubo ezivimbela umlilo. Ingathuthukisa ngokuphumelelayo ukusebenza kwento evimbela ilangabi, ibambezele inqubo yokuvutha, ivimbele ukusabalala kwamalangabi, futhi yehlise ukukhishwa kwamagesi ayingozi nentuthu.

 

Indlela yokulungisa i-ammonium polyphosphate ngokuvamile ihilela ukusabela kwe-phosphoric acid nosawoti we-ammonium. Ngesikhathi sokusabela, izibopho zamakhemikhali phakathi kwe-phosphate ne-ammonium ions ziyakhiwa, zakha ama-polymers anamayunithi amaningi e-phosphate ne-ammonium ion.

 

Ulwazi Lokuphepha: I-Ammonium polyphosphate iphephile uma kuqhathaniswa ngaphansi kwezimo zokusetshenziswa okuvamile nezimo zokuyigcina. Gwema ukuhogela uthuli lwe-ammonium polyphosphate ngoba lungabangela izinkinga zokuphefumula. Lapho uphatha i-ammonium polyphosphate, landela ngokuqinile izinqubo ezifanele zokusebenza zokuphepha futhi ugcine kahle futhi ulahle inhlanganisela.
