Bawo ni ammonium polyphosphate n ṣiṣẹ ni Polypropylene (PP)?

 Polypropylene (PP) jẹ ohun elo thermoplastic ti a lo lọpọlọpọ, ti a mọ fun awọn ohun-ini ẹrọ ti o dara julọ, resistance kemikali, ati resistance ooru.Sibẹsibẹ, PP jẹ flammable, eyiti o ṣe opin awọn ohun elo rẹ ni awọn aaye kan.Lati koju ọrọ yii, iṣakojọpọ ti ammonium polyphosphate (APP) gẹgẹbi idaduro ina ni PP ti ni iwadi lọpọlọpọ.

Ammonium polyphosphate, iru kan ti intumescent ina retardant, ti wa ni afikun si PP lati mu awọn oniwe-ina resistance.Nigbati PP pẹlu APP ba farahan si awọn iwọn otutu giga nigba ina, ammonium polyphosphate decomposes ati tu amonia silẹ, eyiti o dilutes ifọkansi ti awọn gaasi flammable ti a ṣe lakoko ijona.Ilana yii dinku agbara fun ijona ati fa fifalẹ itankale ina.

Pẹlupẹlu, agbara char-forming ti ammonium polyphosphate n ṣe iranlọwọ lati ṣe irẹwẹsi iduroṣinṣin ati aabo lori oju ohun elo PP nigbati o ba farahan si ooru tabi ina.Ipele eedu yii n ṣiṣẹ bi idena, idabobo PP ti o wa ninu ooru ati idinku itusilẹ ti awọn gaasi ina, nitorinaa imudara awọn ohun-ini idaduro ina ti ohun elo PP.

Ni akojọpọ, afikun ti ammonium polyphosphate si PP kii ṣe idinku ina ti ohun elo nikan nipasẹ diluting awọn gaasi flammable ṣugbọn tun ṣe agbega dida ti ẹwa ẹwa aabo, nitorinaa imudara imudara ina gbogbogbo ti awọn pilasitik PP.Eyi jẹ ki PP pẹlu ammonium polyphosphate jẹ aṣayan ifẹ fun awọn ohun elo nibiti aabo ina jẹ pataki julọ.

Taifeng Flame retardant TF-241 jẹ idapọpọ APP II ni iṣẹ imuduro ina giga ni PP ati HDPE.
