Ammonium polyphosphate (APP) inoshandiswa zvakanyanya murazvo retardant uye fetiraiza, inozivikanwa nekubudirira kwayo mukusimudzira kudzivirira kwemoto muzvinhu zvakasiyana. Imwe yemaitiro akakosha ekuongorora anoshandiswa kunzwisisa kupisa kwe APP ndeye Thermogravimetric Analysis (TGA). TGA inoyera shanduko yehuremu hwechinhu sezvo ichidziya, kutonhodzwa, kana kubatwa patembiricha isingaperi, ichipa ruzivo rwakakosha mukugadzikana kwayo kwekupisa, maitiro ekuora, uye kuita kwese mukushandisa.
Kukosha kweTGA mukudzidza kweammonium polyphosphate hakugone kuwedzeredzwa. Chekutanga uye chakakosha, TGA inobatsira pakuona kugadzikana kwekupisa kweAPP. Kunzwisisa tembiricha yemhando iyo APP inoramba yakagadzikana kwakakosha pakushandiswa kwayo mukunonoka kwemoto. Kana APP ikaora nekudzikira tembiricha, inogona kusashanda mukudzivirira zvinhu kubva kumoto, sezvo yaizorasikirwa nezvinhu zvayo zvinodzora moto zvinhu zvacho zvisati zvasvika pakupisa kwakanyanya. TGA inobvumira vatsvakurudzi kuti vaone kutanga kwekuora, zvichiita kuti vagone kukwidziridza maumbirwo ezvimwe zvikumbiro.
Zvakare, TGA inopa manzwisisiro muzvigadzirwa zvekuora zveAPP. Kupisa kwekupisa kweammonium polyphosphate kunogona kutungamirira mukusunungurwa kwemagasi akasiyana-siyana, kusanganisira ammonia uye phosphoric acid. Nekuongorora kurasikirwa kwemazhinji pamatanho akasiyana etembiricha, vaongorori vanogona kuona iwo chaiwo tembiricha siyana panoburitswa magasi aya. Ruzivo urwu rwakakosha pakunzwisisa magadzirirwo emurazvo wemoto, sezvo kuburitswa kwemagasi asingabatike kunogona kuderedza hupfu hunopfuta uye kuderedza kupisa kwese kwechinhu.
Chimwe chinhu chakakosha cheTGA ibasa rayo mukugadzirwa kweApp-based composite. Mumashandisirwo mazhinji, APP inosanganiswa nezvimwe zvinhu kuti iwedzere kuita kwayo. TGA inogona kushandiswa kuongorora kuenderana uye kugadzikana kweaya macomposites pasi pekupisa kwekushushikana. Nekuongorora maitiro ekupisa emidziyo inoumbwa, vaongorori vanogona kuona iyo yakakwana reshiyo yeAPP kune zvimwe zvikamu, vachiona kuti chigadzirwa chekupedzisira chinochengetedza zvimiro zvayo zvinodzora moto uku uchiwana chinodiwa chemuchina uye chinopisa.
Uyezve, TGA inogona kubatsira mukudzora kwemhando panguva yekugadzirwa kweammonium polyphosphate. Nekumisa iyo inopisa mbiri yeAPP, vagadziri vanogona kutarisa kuenderana uye mhando yezvigadzirwa zvavo. Kutsauka kubva pamaitiro akaiswa ekupisa kunogona kuratidza nyaya mukugadzira, senge kusakwana kwekuita kana kusvibiswa, izvo zvinogona kukanganisa kushanda kwemurazvo wemoto.
Mukupedzisa, kukosha kweTGA mukudzidza kweammonium polyphosphate kuri mukukwanisa kwayo kupa ruzivo rwakakosha pamusoro pekugadzikana kwekupisa, maitiro ekuora, uye kuenderana nezvimwe zvinhu. Iyi nzira yekuongorora haingowedzere manzwisisiro edu ekuita kweAPP senge inodzora murazvo asiwo inoita basa rakakosha mukuvandudza uye kutonga kwemhando yezvigadzirwa zveAPP-based. Sezvo maindasitiri achiramba achitsvaga mhinduro dzinoshanda dzekuchengetedza moto, ruzivo rwakawanikwa kubva kuTGA rucharamba ruchikosha mukusimudzira kushandiswa kweammonium polyphosphate munzvimbo dzakasiyana siyana.
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.
