Kusakhazikika kwa Mtengo wa Phosphorus Yachikasu Kumaika Kupanikizika kwa Mtengo pa Msika wa Ammonium Polyphosphate

Kusintha kwakukulu kwa mitengo ya phosphorous yachikasu kwayambitsa kusokonezeka kwakukulu kwa mitengo m'makampani opanga ammonium polyphosphate (APP), zomwe zachepetsa phindu la opanga zinthu zoletsa moto ndi feteleza mdziko lonselo.

Monga chakudya chachikulu cha phosphoric acid ndi phosphoric pentoxide—zofunikira kwambiri pa APP yapamwamba—phosphorous yachikasu yakwera pafupifupi 18% sabata iliyonse chifukwa cha kuchepa kwa magetsi komanso kupezeka kochepa m'malo akuluakulu opangira zinthu kumwera chakumadzulo kwa China. Deta yamakampani ikuwonetsa kuti kukwera kulikonse kwa RMB 1,000/tani kwa phosphorous yachikasu kumakweza mtengo wopangira APP ndi 10% mpaka 15%. Opanga angapo apakatikati a APP ayimitsa maoda otsika mtengo kuti apewe kutayika.

APP imapereka zofunikira ziwiri: zinthu zoletsa moto zopanda halogen zophikira zomangira ndi feteleza wosungunuka m'madzi waulimi. Ogula omwe ali ndi mapangano okhazikika a nthawi yayitali amakhala ndi kukwera mtengo kwakukulu, pomwe opanga mankhwala ang'onoang'ono amakumana ndi mphamvu yotsika yamitengo. Akatswiri akuchenjeza kuti kusakhazikika kwa phosphorous yachikasu kudzachedwetsa kukhazikika kwa mitengo ya APP mpaka magetsi atachepa ndipo zinthu zopangira zinthu zitabwereranso kumapeto kwa Julayi.

Sichuan Taifeng New Flame Retardant Co., Ltd. ndi kampani yopanga zinthu zaukadaulo zapamwamba zoletsa moto zopanda halogen. Imagwira ntchito zosiyanasiyana za ammonium polyphosphate, kuphatikiza kafukufuku ndi chitukuko, kupanga ndi kugulitsa padziko lonse lapansi. Zinthu zake zoletsa phosphorous-nitrogen zomwe zimakhala zotetezeka ku chilengedwe zimapereka mapulasitiki, zokutira ndi nsalu zokhala ndi khalidwe lokhazikika komanso ziphaso zonse zovomerezeka padziko lonse lapansi.
