Kuchinja-chinja kwemitengo yefosforasi yero kwakakonzera kushamisika kukuru kwemitengo mumakambani emaindasitiri eammonium polyphosphate (APP), zvichideredza purofiti yevagadziri vemafuta anodzivirira moto nefetereza munyika yese.
Senzvimbo huru yekudyara phosphoric acid nephosphorus pentoxide—zvinhu zvakakosha zveAPP yepamusoro—yellow phosphorus yakakwira ne18% vhiki nevhiki pakati pemagetsi asina kugadzikana uye kuwanikwa kwakawanda munzvimbo huru dzekugadzira kuchamhembe kwakadziva kumadokero kweChina. Ruzivo rweindasitiri runoratidza kuti kukwira kwega kwega kweyellow phosphorus yeRMB 1,000/tani kunowedzera mitengo yekugadzira APP ne10% kusvika 15%. Vagadziri veAPP vepakati nepakati vakambomisa kuodha kwemitengo yakaderera kudzivirira kurasikirwa.
APP inopa zvinodiwa zviviri: zvinodzivisa moto zvisina halogen zvemachira ekuvaka uye fetereza inonyungudika mumvura yekurima. Vatengi vepasi pemvura vane zvibvumirano zvenguva refu zvakatarwa ndivo vanonyanya kukwira mitengo, nepo michina midiki yemakemikari inotarisana nesimba remitengo risina kusimba. Vaongorori vanonyevera kuti kusagadzikana kwephosphorus yero kunoramba kuripo kuchanonotsa kugadzikana kwemitengo yeAPP kusvika magetsi aderera uye zvinhu zvakagadzirwa zvazadzwa pakupera kwaChikunguru.
Sichuan Taifeng New Flame Retardant Co., Ltd. inyanzvi yekugadzira zvinhu zvinodzivirira moto zvisina halogen. Inonyanya kugadzira zvinhu zvakasiyana-siyana zveammonium polyphosphate, zvichibatanidza R&D, kugadzira uye kutengesa pasi rose. Zvinhu zvayo zvinodzivirira phosphorus-nitrogen zvine hushamwari nezvakatipoteredza zvinopa mapurasitiki, machira uye machira ane hunhu hwakagadzikana uye zvitupa zvakakwana zvekutevedzera mitemo yepasi rose.
