Ammonium polyphosphate (APP) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri poletsa malawi komanso feteleza, omwe amadziwika ndi mphamvu yake powonjezera kukana moto muzinthu zosiyanasiyana. Imodzi mwa njira zowunikira zowunikira zomwe zimagwiritsidwa ntchito kuti amvetsetse kutentha kwa APP ndi Thermogravimetric Analysis (TGA). TGA imayesa kusintha kwa kuchuluka kwa chinthu pamene chitenthedwa, kuziziritsidwa, kapena kusungidwa kutentha kosasintha, kupereka chidziwitso chofunikira pa kukhazikika kwake kwa kutentha, khalidwe la kuwonongeka, ndi momwe zimagwirira ntchito pazogwiritsidwa ntchito.
Kufunika kwa TGA mu kafukufuku wa ammonium polyphosphate sikungatheke. Choyamba, TGA imathandiza kudziwa kukhazikika kwa kutentha kwa APP. Kumvetsetsa kuchuluka kwa kutentha komwe APP imakhalabe yokhazikika ndikofunikira kuti igwiritsidwe ntchito pakuchepetsa moto. Ngati APP iwola pakutentha kocheperako, ikhoza kukhala yosagwira ntchito poteteza zida kumoto, chifukwa imatha kutaya mphamvu zake zoletsa kuyatsa zinthuzo zisanafike kutentha kwambiri. TGA imalola ofufuza kuti azindikire kuyambika kwa kuwonongeka, zomwe zimawathandiza kukhathamiritsa mapangidwe azinthu zinazake.
Kuphatikiza apo, TGA imapereka chidziwitso pazowonongeka za APP. Kuwonongeka kwa kutentha kwa ammonium polyphosphate kungayambitse kutulutsa mpweya wosiyanasiyana, kuphatikizapo ammonia ndi phosphoric acid. Popenda kutayika kwa misa pazigawo zosiyanasiyana za kutentha, ochita kafukufuku amatha kudziwa kutentha komwe kumatuluka mpweya umenewu. Chidziwitsochi ndi chofunikira kuti timvetsetse momwe zimagwirira ntchito kuti moto usapse, chifukwa kutuluka kwa mpweya wosayaka kumatha kutsitsa nthunzi yoyaka ndikuchepetsa kuyaka konse kwa zinthuzo.
Chinanso chofunikira kwambiri pa TGA ndi gawo lake pakupanga ma composites ozikidwa pa APP. Muzinthu zambiri, APP imaphatikizidwa ndi zida zina kuti ipititse patsogolo magwiridwe ake. TGA ikhoza kugwiritsidwa ntchito kuyesa kuyanjana ndi kukhazikika kwa zophatikizika izi pansi pa kupsinjika kwamafuta. Powunika momwe zimatenthetsera zida zophatikizika, ofufuza amatha kudziwa momwe APP imayendera ndi zigawo zina, kuwonetsetsa kuti chomalizacho chimasungabe zinthu zomwe sizimayaka moto ndikukwaniritsa zomwe amafunikira pamakina ndi matenthedwe.
Kuphatikiza apo, TGA imatha kuthandizira pakuwongolera kwabwino pakupanga ammonium polyphosphate. Pokhazikitsa mbiri yamafuta a APP, opanga amatha kuyang'anira kusasinthika ndi mtundu wazinthu zawo. Kupatuka kwa chikhalidwe chokhazikika cha kutentha kumatha kuwonetsa zovuta pakupangira, monga kusakwanira kapena kuipitsidwa, zomwe zitha kusokoneza mphamvu ya choletsa moto.
Pomaliza, kufunikira kwa TGA pakufufuza kwa ammonium polyphosphate kwagona pakutha kupereka chidziwitso chofunikira chokhudza kukhazikika kwamafuta, machitidwe owola, komanso kugwirizana ndi zinthu zina. Njira yowunikirayi sikuti imangowonjezera kumvetsetsa kwathu momwe APP imagwirira ntchito ngati yoletsa moto komanso imagwira ntchito yofunika kwambiri pakupanga ndi kuwongolera zabwino zazinthu zopangidwa ndi APP. Pamene mafakitale akupitirizabe kufunafuna njira zothetsera chitetezo cha moto, zidziwitso zomwe zapezedwa kuchokera ku TGA zidzakhalabe zamtengo wapatali popititsa patsogolo ntchito ya ammonium polyphosphate m'madera osiyanasiyana.
Malingaliro a kampani Sichuan Taifeng New Flame Retardant Co., Ltdndi wopanga yemwe ali ndi zaka 22 wokhazikika pakupanga ammonium polyphosphate retardants lamoto, zopangira zathu zimatumizidwa kunja kwina.
Woyimilira wathu wamoto retardantMtengo wa TF-241ndi eco-ochezeka komanso zachuma, ili ndi ntchito yokhwima mu PP, PE, HEDP.
Ngati mukufuna kudziwa zambiri, chonde titumizireni.
