Ammonium Polyphosphate' applicaiton mu zozimitsa moto za ufa wowuma

Ammonium polyphosphate (APP) ndi mankhwala osakhazikika omwe amagwiritsidwa ntchito kwambiri muzozimitsa moto ndi zozimitsa moto. Njira yake yamankhwala ndi (NH4PO3) n, pomwe n imayimira kuchuluka kwa polymerization. Kugwiritsa ntchito kwa APP muzozimitsira moto kumadalira kwambiri zozimitsa moto komanso kuletsa utsi.

Choyamba, gawo lalikulu la APP muzozimitsa moto ndi ngati choletsa moto. Imalepheretsa kufalikira kwa malawi ndi njira yoyaka moto kudzera m'njira zosiyanasiyana. APP imawola pakatentha kwambiri kuti ipange phosphoric acid ndi ammonia. Phosphoric asidi amapanga galasi zoteteza filimu pa kuyaka pamwamba, kudzipatula mpweya ndi kutentha, potero kupewa kupitiriza kuyaka. Ammonia imathandiza kuchepetsa mpweya woyaka m'malo oyaka komanso kuchepetsa kutentha kwa lawi.

Kachiwiri, APP ili ndi katundu wabwino woletsa utsi. Pamoto, utsi sumangochepetsa kuwonekera komanso kumawonjezera zovuta zothawa, komanso zimakhala ndi mpweya wambiri wapoizoni, zomwe zimawopseza kwambiri thanzi la munthu. APP imatha kuchepetsa kutulutsa utsi panthawi yakuyaka ndikuchepetsa kuvulaza kwamoto.

Ammonium polyphosphate amagwiritsidwa ntchito pozimitsa moto m'njira zosiyanasiyana, zomwe zofala kwambiri ndi zozimitsa moto za ufa wouma ndi zozimitsira moto za thovu. Muzozimitsira moto za ufa wouma, ammonium polyphosphate ndi chimodzi mwa zinthu zofunika kwambiri ndipo amasakanizidwa ndi mankhwala ena kuti apange ufa wowuma wozimitsa moto. Ufa wowumawu ukhoza kuphimba zinthu zoyaka msanga, kuchotsa mpweya, ndikuzimitsa motowo mwachangu. Muzozimitsira moto wa thovu, ammonium polyphosphate amasakanikirana ndi thovu kuti apange thovu lokhazikika lomwe limaphimba pamwamba pa zinthu zoyaka moto, zomwe zimagwira ntchito yoziziritsa ndikupatula mpweya.

Kuphatikiza apo, ammonium polyphosphate imakhalanso ndi zabwino zoteteza chilengedwe komanso kawopsedwe kochepa. Poyerekeza ndi miyambo halogenated lawi retardants, ammonium polyphosphate samasula halide zoipa pa kuyaka, kuchepetsa kuwononga chilengedwe ndi thupi la munthu. Chifukwa chake, kugwiritsa ntchito ammonium polyphosphate muzozimitsa moto zamakono kwalandira chidwi chochulukirapo.

Nthawi zambiri, kugwiritsa ntchito ammonium polyphosphate muzozimitsa moto kuli ndi maubwino angapo, kuphatikiza magwiridwe antchito oletsa moto, mphamvu yabwino yoletsa utsi, komanso kuteteza chilengedwe komanso kawopsedwe wochepa. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kuwongolera zofunikira za anthu pachitetezo ndi kuteteza chilengedwe, chiyembekezo chogwiritsa ntchito ammonium polyphosphate muzozimitsa moto chidzakhala chokulirapo.
