I-Ammonium Polyphosphate Flame Retardant Mechanism kanye nenzuzo

I-Ammonium Polyphosphate I-Flame Retardant Mechanism kanye ne-Advantage

I-Ammonium polyphosphate (APP) i-flame retardant ingahlukaniswa ngezinhlobo ezintathu ngokuya ngezinga layo le-polymerization: i-polymerization ephansi, emaphakathi, nephezulu. Uma iphezulu idigri ye-polymerization, iyancipha ukuncibilika kwamanzi, futhi okuphambene nalokho. Ngokwesakhiwo, ingahlukaniswa ibe amafomu e-crystalline kanye ne-amorphous, ne-crystalline APP ibe usawoti omude ongancibiliki emanzini. Ifomula evamile yemolekyuli ye-APP ithi (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Uma n isukela ku-10 kuye ku-20, iyancibilika emanzini; lapho n idlula 20, iba engancibiliki. I-APP ayinabo ubuthi, ayinaphunga, ayigqwali, futhi ibonisa i-hygroscopicity ephansi, ukuqina kokushisa okuphezulu, nokusebenza okuhle kakhulu njengesinqamuleli somlilo esingena-halogen.

I-Flame Retardant Mechanism ye-APP:
Uma ishiswa, i-APP iyabola ukuze yakhe i-poly-/metaphosphoric acid, ekhuthaza ukuphelelwa amanzi emzimbeni kanye ne-carbonization ebusweni bezinto eziphilayo. Iyanwebeka lapho kushiswa, yenze ungqimba oluvikelayo oluhlukanisa okokusebenza ku-oxygen, ngaleyo ndlela ifinyelele ukuncipha komlilo. Ukwengeza, ukubola okushisayo kwe-APP kukhipha amagesi angashi njenge-CO₂ ne-NH₃, ahlanza ukugcwala komoyampilo emoyeni, aphinde anqande ukutholakala komoyampilo. Lezi zici ziholela ekukhiqizweni kwentuthu ephansi, akukho ukukhiqizwa kwegesi enobuthi, kanye nezindawo zokuzicisha ngokwazo. Ngokuphawulekayo, ukungabi khona kwamagesi anobuthi akugcini nje ngokuphatha imvelo kodwa futhi kubalulekile ekuphepheni ukuphila—izibalo zibonisa ukuthi abantu abangaphezu kuka-80% abashona ezenzakalweni ezinkulu zomlilo babangelwa intuthu enobuthi ephuma kumapulasitiki avuthayo, izakhi zikagesi, nezinye izinto, kunokuba amalangabi ngokwawo.

Umkhiqizi we-APP I-Flame Retardant:
I-Taifeng Flame Retardant isebenzisa ubuchwepheshe be-microencapsulation obusezingeni eliphezulu emhlabeni wonke ukuze ikhiqize i-high-polymerization-degree APP enokuqukethwe okuphezulu kwe-phosphorus ne-nitrogen. Umkhiqizo ubonisa ukuzinza okuhle kakhulu kokushisa, ukuncibilika kwamanzi okuphansi, i-pH engathathi hlangothi, nokusebenza kahle okuphezulu kwe-flame-retardant. Iyimpushana emhlophe eqinile, engashisi, engashi, futhi ibonisa isisindo samangqamuzana aphezulu (n > 1200), ukuzinza, kanye nokumelana nesimo sezulu. Isetshenziswa kabanzi emigqonyeni yokuvikela umlilo esekelwe emanzini, ekwakhiweni kwezindwangu, futhi njengengxenye eyinhloko ku-thermoplastics ye-intumescent flame-retardant. Umkhiqizo ohlanganisiwe wenziwa ukwelashwa okungaphezulu kokuhambisana okuthuthukisiwe, ukumelana nomswakama okuthuthukisiwe, i-alkaline pH, ngisho nokuncibilika okuphansi kwamanzi.
