Njira Yopewera Moto ya Ammonium Polyphosphate ndi Ubwino Wake

Njira ndi Ubwino wa Ammonium Polyphosphate Flame Retardant

Choletsa moto cha Ammonium polyphosphate (APP) chingagawidwe m'magulu atatu kutengera kuchuluka kwa polymerization yake: polymerization yotsika, yapakati, ndi yapamwamba. Mlingo wa polymerization ukakwera, kusungunuka kwa madzi kumachepa, ndipo mosemphanitsa. Mwa kapangidwe kake, chingagawidwe m'mitundu ya kristalo ndi yopanda mawonekedwe, pomwe crystalline APP imakhala mchere wosasungunuka m'madzi wautali. Fomula yonse ya APP ndi (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Pamene n ili pakati pa 10 ndi 20, imasungunuka m'madzi; pamene n ipitirira 20, imakhala yosasungunuka. APP si poizoni, yopanda fungo, yosawononga, ndipo imakhala ndi hygroscopicity yochepa, kutentha kwambiri, komanso magwiridwe antchito abwino kwambiri ngati choletsa moto chopanda halogen.

Njira Yopewera Moto ya APP:
Ikatenthedwa, APP imawola kupanga poly-/metaphosphoric acid, yomwe imalimbikitsa kusowa madzi m'thupi komanso carbonization pamwamba pa zinthu zachilengedwe. Imakula ikatenthedwa, ndikupanga gawo loteteza lomwe limalekanitsa zinthuzo ndi mpweya, motero zimapangitsa kuti moto uchepe. Kuphatikiza apo, kuwonongeka kwa kutentha kwa APP kumatulutsa mpweya wosayaka monga CO₂ ndi NH₃, womwe umachepetsa kuchuluka kwa mpweya mumlengalenga, ndikuchepetsa mpweya woperekedwa. Makhalidwe amenewa amachititsa kuti utsi utuluke pang'ono, mpweya woipa usakhale wopangidwa, komanso mphamvu zozimitsira zokha. Chochititsa chidwi n'chakuti, kusowa kwa mpweya woopsa sikuti kumangoteteza chilengedwe komanso ndikofunikira kwambiri pa chitetezo cha moyo - ziwerengero zikuwonetsa kuti anthu opitilira 80% omwe amafa paziwopsezo zazikulu zamoto amayamba chifukwa cha utsi woopsa wochokera ku mapulasitiki oyaka, zida zamagetsi, ndi zinthu zina, m'malo mwa malawi okha.

Wopanga APP Flame Retardant:
Taifeng Flame Retardant imagwiritsa ntchito ukadaulo wapamwamba kwambiri padziko lonse lapansi wa microencapsulation kuti ipange APP yapamwamba kwambiri yokhala ndi phosphorous ndi nayitrogeni wambiri. Chogulitsachi chili ndi kukhazikika kwabwino kwa kutentha, kusungunuka pang'ono kwa madzi, pH yocheperako, komanso mphamvu yayikulu yoletsa moto. Ndi ufa woyera wolimba, wosasinthasintha, wosayaka, ndipo uli ndi kulemera kwakukulu kwa mamolekyulu (n > 1200), kukhazikika, komanso kukana nyengo. Chimagwiritsidwa ntchito kwambiri mu zophimba zozimitsira moto zochokera m'madzi, zophimba nsalu, komanso ngati gawo lofunikira mu thermoplastics yoletsa moto yomwe imalowa mkati. Chogulitsachi chimathandizidwa pamwamba kuti chigwirizane bwino, chiteteze chinyezi kwambiri, pH ya alkaline, komanso kusungunuka kochepa kwa madzi.
