Ammonium Polyphosphate (APP)
Ammonium Polyphosphate (APP) ndi chinthu choletsa moto chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri popanga zophimba moto zomwe zimateteza moto. Chophimba moto chomwe chimateteza moto chomwe chimateteza moto ndi chinthu chapadera chomwe chimateteza moto. Ntchito yake yayikulu ndikupanga gawo loteteza kutentha kudzera mu mpweya woletsa moto womwe umapangidwa ndi kukulitsa kuti moto usafalikire komanso kupewa kuwonongeka kwa nyumba zikayaka moto.
Mfundo yaikulu
Ammonium polyphosphate imagwiritsidwa ntchito ngati choletsa moto chachikulu mu zophimba moto zomwe zimayaka moto. Ammonium polyphosphate ili ndi mphamvu zabwino zoletsa moto. Kutentha kukakwera, imawola kuti ipange phosphoric acid ndi mpweya wa ammonia. Zinthuzi zimatha kunyowetsa zinthu zachilengedwe kukhala makala, motero zimateteza mpweya ndi kutentha, zomwe zimapangitsa kuti ziwotchedwe. Nthawi yomweyo, ammonium polyphosphate nayonso ndi yayikulu. Ikatenthedwa ndikuwola, imapanga mpweya wambiri, kotero kuti chophimbacho chosayaka moto chimapanga kaboni wokhuthala wosayaka moto, womwe umachotsa bwino gwero la moto kuti lisakhudze ndikuletsa moto kufalikira.
Ubwino
Ammonium polyphosphate ili ndi ubwino wokhala ndi kutentha kwabwino, kukana madzi ndi chinyezi, si poizoni komanso siipitsa chilengedwe, kotero imagwiritsidwa ntchito kwambiri mu zophimba zoteteza moto zomwe zimalowa mkati mwa thunthu. Ikhoza kuwonjezeredwa ku zinthu zoyambira za zophimba zoteteza moto kuti ipange dongosolo lonse la zophimba zoteteza moto pamodzi ndi zinthu zina zotetezera moto, zomangira ndi zodzaza. Kawirikawiri, kugwiritsa ntchito ammonium polyphosphate mu zophimba zoteteza moto zomwe zimalowa mkati mwa thunthu kungapereke mawonekedwe abwino kwambiri oletsa moto komanso kukula, komanso kuteteza bwino chitetezo cha nyumba ndi nyumba zomwe zili pamoto.
Kugwiritsa ntchito
Malinga ndi zofunikira zosiyanasiyana pa APP, kugwiritsa ntchito ammonium polyphosphate mu kupaka utoto kumawonetsedwa makamaka mu:
1. Chophimba cha FR chopangidwa ndi intumescent pa kapangidwe ka chitsulo chamkati.
2. Kuphimba nsalu kumbuyo kwa makatani, chophimba chakuda.
3. Chingwe cha FR.
4. Chogwiritsidwa ntchito kwambiri pomanga, kuyendetsa ndege, ndi kuphimba pamwamba pa sitima.
