Isebenza kanjani i-ammonium polyphosphate ku-Polypropylene (PP)?

 I-Polypropylene (PP) iyimpahla esetshenziswa kakhulu ye-thermoplastic, eyaziwa ngezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali, nokumelana nokushisa.Kodwa-ke, i-PP iyavutha, ekhawulela ukusetshenziswa kwayo kwezinye izinkambu.Ukubhekana nalolu daba, ukufakwa kwe-ammonium polyphosphate (APP) njenge-flame retardant ku-PP kuye kwafundwa kabanzi.

I-Ammonium polyphosphate, uhlobo lwe-intumescent flame retardant, yengezwa ku-PP ukuthuthukisa ukumelana kwayo nomlilo.Uma i-PP ene-APP ichayeka emazingeni okushisa aphezulu ngesikhathi somlilo, i-ammonium polyphosphate iyabola futhi ikhiphe i-ammonia, enciphisa ukugcwala kwamagesi avuthayo akhiqizwa ngesikhathi sokusha.Le nqubo inciphisa amandla okuvutha futhi ibambezela ukusakazeka kwamalangabi.

Ngaphezu kwalokho, ikhono lokwenza i-char ye-ammonium polyphosphate lisiza ukwakha ungqimba oluqinile lwe-char oluvikelayo ebusweni bempahla ye-PP lapho ivezwa ukushisa noma ilangabi.Lesi sendlalelo se-char sisebenza njengesithiyo, sivala i-PP engaphansi ekushiseni futhi sinciphise ukukhululwa kwamagesi avuthayo, ngaleyo ndlela sithuthukise izakhiwo ezivimbela umlilo zezinto ze-PP.

Kafushane, ukungezwa kwe-ammonium polyphosphate ku-PP akugcini nje ukunciphisa ukuvutha kwezinto ngokuhlambulula amagesi avuthayo kodwa futhi kukhuthaza ukwakheka kwesendlalelo se-char esivikelayo, ngaleyo ndlela kuthuthukisa ukumelana nomlilo okuphelele kwamapulasitiki e-PP.Lokhu kwenza i-PP ene-ammonium polyphosphate ibe yinketho efiselekayo lapho ukuphepha komlilo kubaluleke kakhulu.

I-Taifeng Flame retardant TF-241 iyinhlanganisela ye-APP II inokusebenza kwe-flame retardant ephezulu ku-PP ne-HDPE.
