Ammonium polyphosphate ua haujlwm li cas hauv Polypropylene (PP)?
Polypropylene (PP) yog cov khoom siv thermoplastic dav siv, paub txog nws cov khoom zoo heev, tshuaj lom neeg, thiab ua haujlwm kub.Txawm li cas los xij, PP yog flammable, uas txwv nws cov ntawv thov hauv qee qhov chaw.Txhawm rau hais txog qhov teeb meem no, kev koom ua ke ntawm ammonium polyphosphate (APP) ua cov nplaim hluav taws kub hauv PP tau kawm ntau heev.
Ammonium polyphosphate, ib yam ntawm cov nplaim taws retardant, yog ntxiv rau PP los txhim kho nws cov hluav taws kub.Thaum PP nrog APP raug rau qhov kub thiab txias thaum lub sij hawm hluav taws kub, ammonium polyphosphate decomposes thiab tso tawm ammonia, uas dilutes cov concentration ntawm flammable gases uas ua thaum combustion.Cov txheej txheem no txo qhov muaj peev xwm rau combustion thiab ua kom qeeb ntawm cov nplaim taws.
Tsis tas li ntawd, char-forming muaj peev xwm ntawm ammonium polyphosphate pab tsim kom ruaj khov thiab tiv thaiv char txheej ntawm cov khoom PP thaum nws raug tshav kub lossis nplaim taws.Cov txheej char no ua raws li kev thaiv, thaiv cov hauv paus PP los ntawm tshav kub thiab txo qhov tso tawm ntawm cov pa roj carbon monoxide, yog li txhim kho cov hluav taws kub-retardant khoom ntawm PP khoom.
Hauv cov ntsiab lus, qhov sib ntxiv ntawm ammonium polyphosphate rau PP tsis tsuas yog txo cov nplaim taws ntawm cov khoom siv los ntawm diluting flammable gases tab sis kuj txhawb kev tsim cov txheej txheem tiv thaiv char, yog li txhim kho tag nrho cov hluav taws kub tsis kam ntawm PP yas.Qhov no ua rau PP nrog ammonium polyphosphate yog qhov kev xaiv zoo rau cov ntawv thov uas muaj kev nyab xeeb hluav taws kub yog qhov tseem ceeb tshaj plaws.
Taifeng nplaim retardant TF-241 yog sib xyaw APP II muaj cov nplaim hluav taws kub ua haujlwm zoo hauv PP thiab HDPE.
