Ammonium polyphosphate (APP) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri, omwe amadziwika kwambiri chifukwa cha ntchito yake yoletsa malawi ndi feteleza. Maonekedwe ake apadera amapangitsa kuti ikhale yofunika kwambiri pazinthu zosiyanasiyana, kuphatikiza mapulasitiki, nsalu, ndi zokutira. Kumvetsetsa kukhazikika kwamafuta a ammonium polyphosphate ndikofunikira kuti agwiritsidwe ntchito moyenera, makamaka m'malo otentha kwambiri.
Kuwonongeka kwa ammonium polyphosphate nthawi zambiri kumayambira pa kutentha kwakukulu, nthawi zambiri pafupifupi 200 mpaka 300 digiri Celsius (392 mpaka 572 madigiri Fahrenheit). Pakutentha uku, pawiriyo amakumana ndi kusintha kwamankhwala komwe kungayambitse kutulutsa ammonia ndi phosphoric acid. Pamene kutentha kumawonjezeka kwambiri, makamaka kupitirira madigiri 300 Celsius, ndondomeko yowonongeka imathamanga, zomwe zimapangitsa kuwonongeka kwa mapangidwe a polymeric a APP.
Kuwonongeka kwa kutentha kwa ammonium polyphosphate kumatha kutengera zinthu zingapo, kuphatikiza kulemera kwake kwa mamolekyulu, kupezeka kwa zowonjezera, ndi kapangidwe kake komwe amagwiritsidwa ntchito. Mwachitsanzo, APP yocheperako ya mamolekyulu a APP imakonda kutsika pamatenthedwe otsika poyerekeza ndi mitundu yayikulu yolemetsa yamagulu. Kuonjezera apo, kukhalapo kwa zipangizo zina muzopangidwe zophatikizika kungapangitse kapena kulepheretsa njira yowonongeka, malingana ndi kutentha kwawo ndi kuyanjana ndi APP.
Chimodzi mwazinthu zofunika kwambiri pakutentha kwa ammonium polyphosphate ndi ntchito yake yoletsa malawi. Ikatenthedwa, APP imatha kutulutsa mpweya wosayaka, womwe umachepetsa nthunzi yoyaka ndikuthandizira kuletsa kuyaka. Katunduyu ndi wofunika kwambiri pakugwiritsa ntchito pomwe chitetezo chamoto chimadetsa nkhawa. Komabe, kuchita bwino kwa APP ngati chowongolera moto kumalumikizidwa kwambiri ndi kukhazikika kwake kwamafuta. Ngati APP itsika mwachangu, sizingapereke chitetezo chomwe mukufuna.
Kuphatikiza apo, zinthu zowonongeka za ammonium polyphosphate zitha kukhalanso ndi vuto pa chilengedwe komanso thanzi la anthu. Kutulutsidwa kwa ammonia, mwachitsanzo, kungayambitse kuipitsa mpweya ndipo kungayambitse ngozi ngati mutakoka mpweya wambiri. Chifukwa chake, kumvetsetsa kutentha kwanyengo ndi kutulutsidwa kwa mpweya wotsatira ndikofunikira pakuwunika chitetezo ndi chilengedwe cha zinthu zomwe zili ndi APP.
M'malo ogwiritsira ntchito, ndikofunikira kuganizira momwe angagwiritsire ntchito komanso kuthekera kwa kuwonongeka kwa kutentha mukamagwiritsa ntchito ammonium polyphosphate. Opanga nthawi zambiri amayesa kuwunika kwamafuta, monga kusanthula kwa thermogravimetric (TGA), kuti adziwe kutentha komwe kumawonongeka ndikuwongolera mawonekedwe kuti akhazikike komanso magwiridwe antchito.
Pomaliza, ammonium polyphosphate imayamba kutsika pa kutentha pafupifupi madigiri 200 mpaka 300 Celsius, ndikuwonongeka kwakukulu komwe kumachitika pa kutentha kwambiri. Kukhazikika kwake kwamafuta ndi chinthu chofunikira kwambiri pakuchita bwino kwake ngati choletsa moto komanso kugwiritsidwa ntchito kwake pazonse zosiyanasiyana. Kumvetsetsa zinthu zotenthazi sikumangothandizira kupanga zinthu zotetezeka komanso zogwira mtima komanso zimatsimikizira kutsata malamulo a chilengedwe ndi thanzi. Pomwe kafukufuku akupitilirabe, kuzindikira kwinanso pamatenthedwe a ammonium polyphosphate kudzakulitsa momwe amagwiritsidwira ntchito komanso mbiri yachitetezo m'makampani.
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-201ndi eco-ochezeka komanso ndalama, ali okhwima ntchito zokutira intumescent, nsalu kumbuyo zokutira, pulasitiki, nkhuni, chingwe, zomatira ndi PU thovu.
Ngati mukufuna kudziwa zambiri, chonde titumizireni.
