Kodi ammonium polyphosphate imagwira ntchito bwanji mu Polypropylene (PP)?

 Polypropylene (PP) ndi chinthu chogwiritsidwa ntchito kwambiri chotchedwa thermoplastic, chodziwika bwino chifukwa cha mphamvu zake zabwino kwambiri zamakaniko, kukana mankhwala, komanso kukana kutentha. Komabe, PP imatha kuyaka, zomwe zimalepheretsa kugwiritsidwa ntchito kwake m'magawo ena. Pofuna kuthana ndi vutoli, kugwiritsa ntchito ammonium polyphosphate (APP) ngati choletsa moto mu PP kwaphunziridwa kwambiri.

Ammonium polyphosphate, mtundu wa intumescent lawi retardant, imawonjezeredwa ku PP kuti iwonjezere kukana kwake moto. Pamene PP yokhala ndi APP ikumana ndi kutentha kwakukulu panthawi ya moto, ammonium polyphosphate imawola ndikutulutsa ammonia, yomwe imachepetsa kuchuluka kwa mpweya woyaka womwe umapangidwa panthawi ya moto. Njirayi imachepetsa kuthekera kwa kuyaka ndikuchepetsa kufalikira kwa malawi.

Kuphatikiza apo, mphamvu ya ammonium polyphosphate yopangira char imathandiza kupanga char yokhazikika komanso yoteteza pamwamba pa zinthu za PP ikakumana ndi kutentha kapena malawi. Char iyi imagwira ntchito ngati chotchinga, kuteteza PP yomwe ili pansi pa kutentha ndikuchepetsa kutulutsa kwa mpweya woyaka, motero kumawonjezera mphamvu zoletsa moto za zinthu za PP.

Mwachidule, kuwonjezera kwa ammonium polyphosphate ku PP sikuti kumangochepetsa kuyaka kwa zinthuzo mwa kuchepetsa mpweya woyaka komanso kumathandizanso kupanga chotchinga choteteza, motero kumawonjezera kukana moto kwa mapulasitiki a PP. Izi zimapangitsa PP yokhala ndi ammonium polyphosphate kukhala njira yabwino yogwiritsira ntchito pomwe chitetezo cha moto ndichofunika kwambiri.

Taifeng Flame retardant TF-241 ndi APP II yosakanikirana ili ndi mphamvu yoletsa moto kwambiri mu PP ndi HDPE.
