Ammonium polyphosphate (APP) ifotereza inoshandiswa zvakanyanya uye inodzivisa moto, inozivikanwa nekushanda kwayo mukuwedzera kudzivirira moto muzvinhu zvakasiyana-siyana. Imwe yenzira dzakakosha dzekuongorora dzinoshandiswa kunzwisisa hunhu hwekupisa hweAPP ndeyeThermogravimetric Analysis (TGA). TGA inoyera shanduko muhukuru hwechinhu painopiswa, inotonhodzwa, kana kuchengetwa patembiricha yakaenzana, ichipa ruzivo rwakakosha nezvekugadzikana kwayo pakupisa, maitiro ekuora, uye mashandiro ese mumashandisirwo.
Kukosha kweTGA mukudzidza kweammonium polyphosphate hakugoni kupfuudzwa zvakanyanya. Chekutanga uye chakakosha, TGA inobatsira mukuona kugadzikana kwekupisa kweAPP. Kunzwisisa huwandu hwetembiricha iyo APP inoramba yakagadzikana kwakakosha pakushandiswa kwayo mukudzora moto. Kana APP ikaora patembiricha yakaderera, ingasashanda mukudzivirira zvinhu kubva kumoto, sezvo inogona kurasikirwa nehunhu hwayo hunodzivirira moto usati wasvika patembiricha yakakosha. TGA inobvumira vaongorori kuona kutanga kwekuora, zvichivagonesa kugadzirisa mafomati ekushandisa chaiwo.
Uyezve, TGA inopa ruzivo nezvezvinhu zvinoparara zveAPP. Kuora kwekupisa kweammonium polyphosphate kunogona kutungamira mukuburitswa kwemagasi akasiyana-siyana, kusanganisira ammonia nephosphoric acid. Nekuongorora kurasikirwa kwehuwandu pamatanho akasiyana ekupisa, vaongorori vanogona kuona nzvimbo chaiyo yekupisa uko magasi aya anoburitswa. Ruzivo urwu rwakakosha pakunzwisisa mashandiro ekunonoka kwemoto, sezvo kuburitswa kwemagasi asingabati kunogona kuderedza utsi hunobatidza uye kuderedza kupisa kwechinhu chose.
Chimwe chinhu chakakosha cheTGA ibasa rayo mukugadzira zvinhu zvakagadzirwa neAPP. Mumashandisirwo mazhinji, APP inosanganiswa nezvimwe zvinhu kuti iwedzere kushanda kwayo. TGA inogona kushandiswa kuongorora kuenderana uye kugadzikana kwezvinhu izvi zvakagadzirwa pasi pekumanikidzwa kwekupisa. Nekuongorora maitiro ekupisa kwezvinhu zvakagadzirwa, vaongorori vanogona kuona huwandu hwakakodzera hweAPP nezvimwe zvikamu, vachiona kuti chigadzirwa chekupedzisira chinochengetedza hunhu hwacho hunodzivirira moto uku vachiwana hunhu hwaunoda hwemakanika nekupisa.
Uyezve, TGA inogona kubatsira mukudzora mhando panguva yekugadzirwa kweammonium polyphosphate. Nekugadzira chimiro chekupisa cheAPP, vagadziri vanogona kutarisa kuenderana uye mhando yezvigadzirwa zvavo. Kutsauka kubva pamaitiro ekupisa akajairwa kunogona kuratidza matambudziko mukugadzirwa, akadai sekusakwana kwekuita kana kusvibiswa, izvo zvinogona kukanganisa kushanda kwemuchina unodzora moto.
Mukupedzisa, kukosha kweTGA mukudzidza nezve ammonium polyphosphate kuri mukukwanisa kwayo kupa ruzivo rwakakosha nezvekugadzikana kwekupisa, maitiro ekuora, uye kuenderana nezvimwe zvinhu. Iyi nzira yekuongorora haingowedzere chete kunzwisisa kwedu mashandiro eAPP semushonga unodzivirira moto asiwo inoita basa rakakosha mukuvandudza nekudzora mhando yezvigadzirwa zvinobva kuAPP. Sezvo maindasitiri achiramba achitsvaga mhinduro dzinoshanda dzekuchengetedza moto, nzwisiso yakawanikwa kubva kuTGA icharamba yakakosha mukusimudzira kushandiswa kweammonium polyphosphate muminda yakasiyana-siyana.
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-241Inochengetedza nharaunda uye inodhura zvishoma, ine kushandiswa kwakakura muPP, PE, HEDP.
Kana muchida kuziva rumwe ruzivo, ndapota taurai nesu.
