Ammonium Polyphosphate Flame Retardant Mechanism uye Advantage
Ammonium polyphosphate (APP) flame retardant inogona kuiswa mumhando nhatu zvichienderana nedhigirii repolymerization: yakaderera, yepakati, uye yakakwirira polymerization. Iyo yakakwirira iyo polymerization dhigirii, inodzika iyo kunyungudika kwemvura, uye zvinopesana. Zvimiro, inogona kupatsanurwa kuita crystalline uye amorphous mafomu, ine crystalline APP iri refu-cheni yemvura isinganyungudika munyu. Iyo yakazara molecular formula yeAPP ndeye (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Kana n ichibva pagumi kusvika pamakumi maviri, inonyungudika nemvura; apo n inodarika makumi maviri, inova isinganyunguriki. APP haina muchetura, haina kunhuwa, haina-kuora, uye inoratidza yakaderera hygroscopicity, yakanyanya kugadzikana yekupisa, uye kuita kwakanakisa senge halogen-isina murazvo unodzoreredza.
Flame Retardant Mechanism yeAPP:
Kana yapiswa, APP inoora kuita poly-/metaphosphoric acid, iyo inosimudzira kupera mvura mumuviri uye carbonization pamusoro pezvigadzirwa zve organic. Iyo inowedzera pakudziya, ichigadzira chidziviriro chinoparadzanisa zvinhu kubva kuokisijeni, nekudaro inowana murazvo wemoto. Pamusoro pezvo, kuparara kwekupisa kweAPP kunoburitsa gasi risingabatike rakaita seCO₂ neNH₃, iro rinonatsa kuwanda kweokisijeni mumhepo, zvichiwedzera kucheka kupihwa kweokisijeni. Hunhu uhu hunokonzeresa kuburitsa hutsi hushoma, kusagadzirwa kwegasi rine muchetura, uye kuzvidzima. Sezvineiwo, kusavapo kwemagasi ane chepfu hakungogari kwezvakatipoteredza chete asiwo kwakakosha kuchengetedzwa kwehupenyu-nhamba dzinoratidza kuti pamusoro pe80% yevanhu vanofa muzviitiko zvikuru zvemoto zvinokonzerwa nehutsi hunopisa hunobva mumapurasitiki anopisa, zvigadzirwa zvemagetsi, uye zvimwe zvinhu, panzvimbo pemoto pachawo.
Mugadziri weApp Flame Retardant:
Taifeng Flame Retardant inoshandisa tekinoroji yepamusoro-soro yakawanda-layer microencapsulation kugadzira yakakwirira-polymerization-degree APP ine yakakwira phosphorus uye nitrogen zvirimo. Chigadzirwa chacho chinoratidza kugadzikana kwakanyanya kwekupisa, kunyungudika kwemvura kwakadzika, pedyo-kwakarerekera pH, uye yakakwirira-inodzoreredza moto. Ihupfu huchena hwakasimba, husina-hygroscopic, husingabatike, uye hunoratidza huremu hwepamusoro-soro (n> 1200), kugadzikana, uye kuramba kwemamiriro ekunze. Inoshandiswa zvakanyanya mumvura-based fireproof coatings, machira machira, uye sechinhu chakakosha mu intumescent flame-retardant thermoplastics. Iyo yakavharidzirwa chigadzirwa inorapwa pamusoro pekugadzirisa kuenderana, yakawedzera hunyoro kuramba, alkaline pH, uye kunyange kuderera kwemvura kunyungudika.
