Ammonium polyphosphate (APP) chinhu chinoshandiswa zvakanyanya muzvinhu zvisingasanganisike, chinonyanya kuzivikanwa nebasa rayo semushonga unodzivirira moto uye fetiraiza. Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha mukushandiswa kwakasiyana-siyana, kusanganisira mapurasitiki, machira, uye machira. Kunzwisisa kugadzikana kwekupisa kweammonium polyphosphate kwakakosha pakushandiswa kwayo zvinobudirira, kunyanya munzvimbo dzinopisa zvakanyanya.
Kuora kweammonium polyphosphate kunowanzotanga pakupisa kwakanyanya, kazhinji kunosvika 200 kusvika 300 degrees Celsius (392 kusvika 572 degrees Fahrenheit). Pakupisa uku, chinhu ichi chinoshanduka kuita shanduko dzemakemikari dzinogona kutungamira mukuburitswa kweammonia nephosphoric acid. Sezvo kupisa kuchiwedzera, kunyanya kupfuura 300 degrees Celsius, maitiro ekuora anokurumidza, zvichikonzera kuparara kwechimiro chepolymeric cheAPP.
Kudzikira kwemafuta eammonium polyphosphate kunogona kukanganiswa nezvinhu zvakawanda, zvinosanganisira huremu hwayo hwemamorekuru, kuvapo kwezvinowedzerwa, uye chimiro chaicho chinoshandiswa. Semuenzaniso, huremu hwakaderera hwemamorekuru hweAPP hunowanzo kudzikira patembiricha yakaderera zvichienzaniswa nehukuru hwemamorekuru hwakakwira. Pamusoro pezvo, kuvapo kwezvimwe zvinhu muchimiro chakabatanidzwa kunogona kuwedzera kana kumisa maitiro ekudzikira, zvichienderana nehunhu hwavo hwekupisa uye kudyidzana neAPP.
Chimwe chezvinhu zvakakosha pakushanda kweammonium polyphosphate mukupisa ibasa rayo semushonga unodzivirira moto. Kana ikaiswa pakupisa, APP inogona kuburitsa magasi asingabatike, ayo anoderedza utsi hunobvira moto uye anobatsira kudzikamisa kupisa. Hunhu uhwu hunonyanya kukosha mukushandiswa uko kuchengetedzeka kwemoto kuri dambudziko. Zvisinei, kushanda kweAPP semushonga unodzivirira moto kwakabatana zvakanyanya nekugadzikana kwayo mukupisa. Kana APP ikaora nekukurumidza, ingasapa dziviriro inodiwa.
Uyezve, zvinhu zvinokuvadza zveammonium polyphosphate zvinogonawo kuva nemigumisiro kunharaunda nehutano hwevanhu. Semuenzaniso, kuburitswa kweammonia kunogona kukonzera kusvibiswa kwemhepo uye kunogona kukonzera njodzi kuhutano kana ikafemerwa nehuwandu hwakawanda. Saka, kunzwisisa tembiricha yekuora uye kuburitswa kwemagasi kunotevera kwakakosha pakuongorora kuchengetedzeka uye kukanganisa nharaunda kwezvinhu zvine APP.
Mukushandiswa kwezvinoshanda, zvakakosha kufunga nezvemamiriro ekushanda uye mukana wekuora kwekupisa kana uchishandisa ammonium polyphosphate. Vagadziri vanowanzoita ongororo yekupisa, senge thermogravimetric analysis (TGA), kuti vaone tembiricha chaiyo yekuora uye kugadzirisa mafomura kuti agadzikane uye ashande zvakanaka.
Mukupedzisa, ammonium polyphosphate inotanga kuora patembiricha inosvika 200 kusvika 300 degrees Celsius, uye kuora kwakanyanya kunoitika patembiricha dzakakwirira. Kugadzikana kwayo pakupisa chinhu chakakosha mukushanda kwayo semushonga unodzivirira moto uye kushandiswa kwayo mukushandiswa kwakasiyana-siyana. Kunzwisisa hunhu uhwu hwekupisa hakungobatsiri chete mukugadzirwa kwezvigadzirwa zvakachengeteka uye zvinoshanda asiwo kunovimbisa kutevedzera mitemo yezvakatipoteredza nehutano. Sezvo tsvakiridzo ichienderera mberi, ruzivo rwakawanda pamusoro pehunhu hwekupisa hweammonium polyphosphate ruchawedzera mashandisirwo ayo uye ma profiles ekuchengetedza muindasitiri.
Sichuan Taifeng New Flame Retardant Co., Ltdimugadziri ane ruzivo rwemakore makumi maviri nemaviri anonyanya kugadzira ammonium polyphosphate flame retardants, zvinhu zvedu zvinotengeswa kunze kwenyika zvakanyanya.
mumiririri wedu murazvo unodzoraTF-201Inochengetedza nharaunda uye inodhura zvishoma, inoshandiswa zvakanyanya mu intumescent coatings, textile back coating, mapurasitiki, huni, tambo, zvinonamira uye PU furo.
Kana muchida kuziva rumwe ruzivo, ndapota taurai nesu.
