Indlela yokuGxotha i-Ammonium Polyphosphate Flame kunye neenzuzo zayo

Indlela kunye neNzuzo yeAmmonium Polyphosphate Flame Retardant Mechanism

I-Ammonium polyphosphate (APP) flame retardant inokwahlulwahlulwa ibe ziintlobo ezintathu ngokusekelwe kwinqanaba layo le-polymerization: i-polymerization ephantsi, ephakathi, kunye nephezulu. Okukhona i-polymerization iphezulu, kokukhona ukunyibilika kwamanzi kuphantsi, kwaye okuphambeneyo. Ngokwesakhiwo, inokwahlulwahlulwa ibe ziifom ze-crystalline kunye ne-amorphous, i-crystalline APP iyityuwa enganyibilikiyo emanzini enomtya omde. Ifomula ye-molecule ye-APP ngokubanzi yi-(NH₄)ₙ₊₂PₙO₃ₙ₊₁. Xa i-n iphakathi kwe-10 ukuya kwi-20, iyanyibilika emanzini; xa i-n idlula kwi-20, ayinyibiliki. I-APP ayinatyhefu, ayinavumba, ayibolisi, kwaye ibonisa i-hygroscopicity ephantsi, uzinzo oluphezulu lobushushu, kunye nokusebenza kakuhle njenge-halogen-free flame retardant.

Indlela ye-APP ethintela ilangatye:
Xa ifudunyezwa, i-APP iyabola ukuze yenze i-poly-/metaphosphoric acid, ekhuthaza ukuphelelwa ngamanzi emzimbeni kunye nokufakwa kwekhabhoni kumphezulu wezinto eziphilayo. Iyakhula xa ifudunyezwa, yenze umaleko okhuselayo owahlula izinto kwi-oksijini, ngaloo ndlela ifezekisa ukubambezeleka komlilo. Ukongeza, ukubola kobushushu be-APP kukhupha iigesi ezingatshiyo ezifana ne-CO₂ kunye ne-NH₃, ezinciphisa uxinzelelo lwe-oksijini emoyeni, zithintela ngakumbi ukunikezelwa kwe-oksijini. Ezi mpawu zibangela ukukhutshwa komsi okuphantsi, ukungabikho kwegesi enobuthi, kunye neempawu zokuzicima. Okuphawulekayo kukuba, ukungabikho kweegesi ezinobuthi akupheleli nje ekubeni nobuhlobo nokusingqongileyo kodwa kubalulekile kukhuseleko lobomi—amanani abonisa ukuba ngaphezulu kwe-80% yabantu abafayo kwiziganeko ezinkulu zomlilo zibangelwa ngumsi onobuthi ovela kwiiplastiki ezitshayo, izinto ze-elektroniki, kunye nezinye izinto, endaweni yomlilo ngokwawo.

Umvelisi we-APP Flame Retardant:
I-Taifeng Flame Retardant isebenzisa iteknoloji ye-microencapsulation ephucukileyo kwihlabathi liphela ukuvelisa i-APP ene-polymerization-degree ephezulu enomxholo ophezulu we-phosphorus kunye ne-nitrogen. Le mveliso inozinzo oluhle kakhulu lobushushu, ukunyibilika kwamanzi okuphantsi, i-pH ephantse ingabi nacala, kunye nokusebenza kakuhle kokurhoxisa ilangatye. Yinto emhlophe eyomeleleyo engumgubo, engena-hygroscopic, engatshiyo, kwaye inobunzima obuphezulu beemolekyuli (n > 1200), uzinzo, kunye nokumelana nemozulu. Isetyenziswa kakhulu kwiingubo ezisekelwe emanzini ezingatshiyo, kwiingubo zelaphu, kwaye njengenxalenye ephambili kwi-thermoplastics ezithintela ilangatye ezingaphakathi. Imveliso egqunyiweyo ifumana unyango lomphezulu ukuze ihambelane ngcono, ixhathise ngakumbi ukufuma, i-alkaline pH, kwaye inyibilike namanzi aphantsi.
