Ammonium polyphosphate (APP) inoshandiswa zvakanyanya inorganic compound, inonyanya kuzivikanwa nebasa rayo senge inodzosa moto uye fetireza. Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha mukushandisa kwakasiyana, kusanganisira mapurasitiki, machira, uye machira. Kunzwisisa kugadzikana kwekupisa kweammonium polyphosphate kwakakosha pakushandisa kwayo kunoshanda, kunyanya munzvimbo dzinopisa.
Kushatiswa kweammonium polyphosphate kunowanzotanga patembiricha dzakakwirira, kazhinji dzinotenderedza 200 kusvika 300 madhigirii Celsius (392 kusvika 572 madhigirii Fahrenheit). Pane tembiricha idzi, komboni yacho inosangana neyakatevedzana shanduko yemakemikari inogona kutungamira mukuburitswa kweammonia uye phosphoric acid. Sezvo tembiricha ichiwedzera, kunyanya kupfuura 300 madhigirii celsius, iyo degradation process inowedzera, zvichikonzera kuparara kwepolymeric chimiro cheAPP.
Kupisa kwekupisa kweammonium polyphosphate kunogona kupesvedzerwa nezvinhu zvakati wandei, kusanganisira huremu hwayo hwemamorekuru, kuvapo kwezvinowedzera, uye magadzirirwo chaiwo anoshandiswa. Semuyenzaniso, yakaderera mamorekuru huremu APP inowanzo dzika pa tembiricha yakaderera kana ichienzaniswa neakakwira mamorekuru uremu akasiyana. Pamusoro pezvo, kuvepo kwezvimwe zviwanikwa mumusanganiswa wekugadzira zvinogona kuwedzera kana kumisa maitiro ekudzikisira, zvichienderana nekupisa kwavo zvinhu uye kudyidzana neAPP.
Chimwe chezvinhu zvakakosha zveammonium polyphosphate's thermal maitiro ibasa rayo semurazvo wemoto. Kana yaiswa mukupisa, APP inogona kuburitsa magasi asingabatike, ayo anonatsa hupfu hunopfuta uye anobatsira kudzima moto. Iyi pfuma inonyanya kukosha mumashandisirwo apo kuchengetedzwa kwemoto kuri kunetseka. Nekudaro, kushanda kweAPP semurazvo wemoto wakanyatsobatanidzwa nekugadzikana kwayo kwekupisa. Kana APP ichidzikisira nekukurumidza, inogona kusapa iyo inodiwa mwero wedziviriro.
Zvakare, izvo zvinosvibisa zvigadzirwa zveammonium polyphosphate zvinogona zvakare kuve nezvazvinoreva kune nharaunda uye hutano hwevanhu. Kuburitswa kweammonia, semuenzaniso, kunogona kukonzeresa kusvibiswa kwemhepo uye kunogona kukonzera njodzi dzehutano kana ikafemerwa muhuwandu hwakakosha. Naizvozvo, kunzwisisa tembiricha yekudzikira uye kuburitswa kwemagasi kwakakosha pakuongorora kuchengetedzeka uye kukanganisa kwezvakatipoteredza kwezvigadzirwa zvine APP.
Mumashandisirwo anoshanda, zvakakosha kuti titarise mamiriro ekushanda uye mukana wekupisa kwekupisa kana uchishandisa ammonium polyphosphate. Vagadziri vanowanzoita ongororo yekupisa, senge thermogravimetric analysis (TGA), kuti vatarise iwo chaiwo tembiricha yekushatisa uye nekugadzirisa magadzirirwo ekugadzikana uye kuita.
Mukupedzisa, ammonium polyphosphate inotanga kuderera patembiricha yakatenderedza 200 kusvika 300 madhigirii celsius, nekuderera kukuru kunoitika pakupisa kwepamusoro. Kugadzikana kwayo kwekupisa chinhu chakakosha mukubudirira kwayo senge inodzoreredza murazvo uye kushandiswa kwayo kwese mukushandisa kwakasiyana. Kunzwisisa izvi zvinopisa zvivakwa hazvibatsiri chete mukugadzirwa kwezvakachengetedzeka uye zvinobudirira zvigadzirwa asi zvakare kunovimbisa kutevedza kwezvakatipoteredza uye hutano mirau. Sezvo tsvagiridzo ichienderera mberi, kumwe kunzwisiswa kwemaitiro ekupisa kweammonium polyphosphate kunosimudzira mashandisirwo ayo uye maprofile ekuchengetedza muindasitiri.
Sichuan Taifeng New Flame Retardant Co., Ltdmugadziri ane makore makumi maviri nemaviri ehunyanzvi mukugadzirwa kweammonium polyphosphate flame retardants, zvigadzirwa zvedu zvinotengeswa kunze kwenyika zvakanyanya mhiri kwemakungwa.
Yedu inomiririra murazvo retardantTF-201ine eco-inoshamwaridzika uye ine hupfumi, ine mature application mune intumescent coatings, textile back coating, mapurasitiki, huni, tambo, anonamira uye PU furo.
Kana uchida kuziva mamwe mashoko, tapota taura nesu.
