Isebenza njani i-ammonium polyphosphate kwiPolypropylene (PP)?

 I-Polypropylene (PP) yinto esetyenziswa kakhulu kwi-thermoplastic, eyaziwayo ngeempawu zayo ezigqwesileyo zomatshini, ukuxhathisa iikhemikhali, kunye nokumelana nobushushu.Nangona kunjalo, i-PP inokutsha, ekhawulela usetyenziso lwayo kwezinye iindawo.Ukujongana nalo mbandela, ukufakwa kwe-ammonium polyphosphate (APP) njenge-flame retardant kwi-PP ifundwe ngokubanzi.

I-Ammonium polyphosphate, uhlobo lwe-intumescent flame retardant, yongezwa kwi-PP ukuphucula ukumelana nomlilo.Xa i-PP ene-APP ibonakaliswe kumaqondo okushisa aphezulu ngexesha lomlilo, i-ammonium polyphosphate ibola kwaye ikhuphe i-ammonia, ephazamisa ukuxinwa kweegesi ezinokutsha eziveliswa ngexesha lokutsha.Le nkqubo inciphisa amandla okutsha kwaye iyancipha ukusasazeka kwamadangatye.

Ngaphezu koko, amandla okwenza i-char ye-ammonium polyphosphate inceda ukwenza i-char layer ezinzileyo kunye nekhuselayo ebusweni bezinto zePP xa ibonakaliswe kubushushu okanye ilangatye.Olu luhlu lwe-char lusebenza njengesithintelo, lukhusela i-PP ephantsi ekushiseni kunye nokunciphisa ukukhutshwa kweegesi ezinokutsha, ngaloo ndlela kuphuculwe iipropati ezithintela umlilo kwizinto zePP.

Isishwankathelo, ukongezwa kwe-ammonium polyphosphate kwi-PP akugcini nje ukunciphisa ukutsha kwezinto ngokuxutywa kweegesi ezinokutsha kodwa kukhuthaze ukubunjwa kwe-char layer yokukhusela, ngaloo ndlela kuphuculwe ukuxhathisa komlilo kwiiplastiki zePP.Oku kwenza i-PP kunye ne-ammonium polyphosphate ibe yinto enqwenelekayo kwizicelo apho ukhuseleko lomlilo lubaluleke kakhulu.

I-Taifeng Flame retardant TF-241 idibanisa i-APP II inomsebenzi ophezulu we-flame retardant kwi-PP kunye ne-HDPE.
