Ammonium Polyphosphate (APP)
Ammonium Polyphosphate (APP) ndi chotchinga moto chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri popaka zokutira zozimitsa moto.Chophimba chotchinga moto ndi chotchingira chapadera chozimitsa moto.Ntchito yake yayikulu ndikupanga chotchinga chotchinga kutentha kudzera mumafuta oletsa moto omwe amapangidwa ndi kukulitsa kuti ateteze kufalikira kwa moto ndikuletsa kuwonongeka kwa zomangamanga pakayaka moto.
Mfundo yofunika
Ammonium polyphosphate imagwiritsidwa ntchito ngati chotchinga chachikulu chalawi lamoto muzopaka zoziziritsa moto.Ammonium polyphosphate ali ndi mphamvu yoletsa moto.Kutentha kukakwera, kumawola kupanga phosphoric acid ndi mpweya wa ammonia.Zogulitsazi zimatha kutaya madzi m'thupi kukhala makala, motero zimatsekereza mpweya ndi kutentha, zomwe zimapangitsa kuti moto usavutike.Nthawi yomweyo, ammonium polyphosphate imakhalanso yotambasula.Ikatenthedwa ndikuwonongeka, imatulutsa mpweya wochuluka, kotero kuti chophimba choyaka moto chimapanga mpweya wochuluka wa carbon, womwe umalekanitsa bwino gwero la moto kuti lisagwirizane ndikuletsa kuti moto usafalikire.
Ubwino wake
Ammonium polyphosphate ali ndi ubwino wa kukhazikika kwa kutentha kwabwino, kukana kwa madzi ndi chinyezi, kusakhala ndi poizoni komanso kosawononga chilengedwe, kotero kumagwiritsidwa ntchito kwambiri mu zokutira zoyaka moto.Ikhoza kuwonjezeredwa kuzinthu zapansi za zokutira zozimitsa moto kuti apange dongosolo lathunthu lozimitsa moto pamodzi ndi zoletsa moto, zomangira ndi zodzaza.Nthawi zambiri, kugwiritsa ntchito ammonium polyphosphate mu zokutira zoziziritsa moto kungapereke mawonekedwe abwino kwambiri ochepetsera lawi ndi kukulitsa, komanso kuteteza chitetezo cha nyumba ndi nyumba pamoto.
Kugwiritsa ntchito
Malinga ndi zida zosiyanasiyana zimafunikira pa APP, Kugwiritsa ntchito ammonium polyphosphate pakupaka kumawonekera makamaka mu:
1. Kupaka kwa intumescent FR pakupanga zitsulo zomanga m'nyumba.
2. Zovala kumbuyo zokutira mu makatani, zokutira zakuda.
3. Chingwe cha FR.
4. Zazikulu zomwe zimagwiritsidwa ntchito pomanga, kuyendetsa ndege, zokutira pamwamba pa zombo.
Chitsanzo cha kuphimba kwa intumescent
