Zvenyama uye Chemical Properties	Ammonium polyphosphate inogona kupatsanurwa kuita marudzi matatu zvichienderana nedhigirii repolymerization: yakaderera polymer, yepakati polima, uye yakakwira polymer. Iyo yakakwirira dhigirii yepolymerization, iyo idiki yekunyungudika kwemvura. Zvinoenderana nechimiro chayo, inogona kukamurwa kuva crystalline uye amorphous marudzi. Crystalline ammonium polyphosphate imvura isinganyunguriki uye yakareba-cheni polyphosphate. Pane misiyano mishanu kubva paI kusvika kuV mhando.
Shandisa	Inorganic additive flame retardant, inoshandiswa mukugadzira machira anodzoreredza moto, mapurasitiki anodzoreredza moto uye zvigadzirwa zverabha zvinodzoreredza, nezvimwe. Inonyanya kushandiswa mu intumescent moto retardant coatings uye thermosetting resins (senge polyurethane rigid foam, UP resin, epoxy resin, nezvimwewo), uye inogona kushandiswawo murazvo wefiber, huni uye zvigadzirwa zverabha. Sezvo iyo APP iine huremu hwepamusoro (n> 1000) uye kugadzikana kwepamusoro, inogona zvakare kushandiswa sechinhu chikuru chinoshanda che intumescent flame retardant thermoplastics, kunyanya muPP kusvika kuUL 94-Vo yekugadzira zvikamu zvemagetsi.

Nhanganyaya

Ammonium polyphosphate (PAAP kwenguva pfupi) inorganic polymer ine murazvo wemoto uye isingadziviriri moto. Chimiro chayo chemorekuru chine mapolymers ephosphate uye ammonium ions.

Ammonium polyphosphate inoshandiswa zvakanyanya mumurazvo retardants, refractory zvinhu uye machira anodzoreredza moto. Inogona kunyatso kuvandudza mashandiro anoita murazvo wemoto, kunonoka kupisa, kumisa kupararira kwemirazvo, uye kuderedza kuburitswa kwemagasi anokuvadza uye utsi.

Nzira yekugadzira ammonium polyphosphate inowanzobatanidza maitiro e phosphoric acid uye ammonium munyu. Munguva yekuita, zvisungo zvemakemikari pakati pephosphate neammonium ions zvinoumbwa, zvichiita mapolymers ane multiple phosphate uye ammonium ion units.

Ruzivo Rwekuchengetedza: Ammonium polyphosphate yakachengeteka pasi pekushandiswa kwakajairwa uye kuchengetedza mamiriro. Dzivisa kufema guruva reammonium polyphosphate nekuti rinogona kukonzera matambudziko ekufema. Paunenge uchibata ammonium polyphosphate, nyatsotevera maitiro ekuchengetedza akakodzera uye chengetedza nemazvo uye urase musanganiswa.

Zvakapfuura: Barium sulfate CAS 13462-86-7

Zvinotevera: Pentaerythritol CAS 115-77-5
