Basa Guru reAmmonium PolyphosphatemuFire Retardant Coatings: Synergistic Mhedzisiro neMelamine nePentaerythritol
Ammonium polyphosphate(APP) inoshanda sechinhu chikuru mukugadzirwa kwezvigadzirwa zvemazuva anomachira anodzivisa moto, ichipa dziviriro inoshamisa kubva pakutyisidzirwa nemoto. Hunhu hwayo hwakasiyana, kana ikabatanidzwa nezvimwe zvinhu zvakakosha zvakaita semelamine nepentaerythritol, zvinogadzira kubatana kwakasimba kunowedzera zvakanyanya kushanda kwependi inodzivirira moto.
Sechinhu chinodzora moto zvakanyanya,ammonium polyphosphateinoshanda nenzira ine mativi akawanda. Kana yasangana nekupisa kwakanyanya, inoora yoburitsa phosphoric acid, iyo inobva yasangana ne substrate kuti igadzire char layer inodzivirira. Char layer iyi inoshanda sechidziviriro, ichidzivirira kutsva uye kutamiswa kwekupisa. Pamusoro pezvo, kuburitswa kwemagasi asingatsvi, akadai seammonia neutsi hwemvura, kunobatsira kuderedza huwandu hweokisijeni hwakatenderedza chinhu chiri kutsva, zvichiwedzera kudzvinyirira marimi emoto.
Kunyange zvazvo ammonium polyphateralone ichishanda zvakanaka yoga, kushanda kwayo kunogona kuwedzerwa zvakanyanya kuburikidza nekuwedzera melamine nepentaerythritol. Melamine inobatsira pakuumbwa kwechar layer yakasimba uye yakagadzikana nekupa huwandu hwenitrogen yakawedzerwa. Iyi nitrogen haingowedzeri huwandu hwegasi risingatsvi rinoburitswa chete asiwo inokurudzira kubatana kwechar, zvichiita kuti irambe ichidzivirira kuputsika.
Kune rumwe rutivi, Pentaerythritol inoita basa rakakosha mukuvandudza hunhu hwechipfeko chinodzivirira moto. Sepurasitiki, inowedzera kuchinjika uye kunamira kwechipfeko, ichivimbisa kufukidza kuri nani uye kugara kwenguva refu. Uyezve, pentaerythritol inoshanda semutsigiri wechar, ichibatsira kuumbwa kwechar layer yakakora uye inoramba iripo inodzivirira zvinobudirira zvinhu zviri pasi kubva mumoto.
Musanganiswa we synergistic weammonium polyphosphate, melamine, uye pentaerythritol muzvipfeko zvinodzivirira moto zvinoguma nemhinduro inoshanda uye yakavimbika yekudzivirira moto. Iyi mitatu ine simba haingopi chete kudzivirira moto kwakanaka asiwo inopa hunhu hwakanaka hwemuviri, zvichiita kuti ive sarudzo yakakodzera kune dzakasiyana siyana.
Muchidimbu,ammonium polyphosphateInoonekwa seimwe yemhando dzemachira anodzima moto, ine simba rayo guru rekubatanidza ne melamine ne pentaerythritol. Musanganiswa wezvinhu izvi unoita kuti machira aya arambe achidzivirira moto zvakanyanya, zvichichengetedza hupenyu nepfuma.
Sichuan Taifeng New Flame Retardant Co., Ltdinyanzviammonium polyphosphatemugadziri muChina ane makore makumi maviri nemaviri eruzivo. APP TF-201 chigadzirwa chakakurumbira uye chakakura chinogamuchirwa neEU, India, Southeast Asia.
