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

 I-Polypropylene (PP) iyinto esetshenziswa kakhulu ye-thermoplastic, eyaziwa ngezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali, kanye nokumelana nokushisa. Kodwa-ke, i-PP iyavutha, okunciphisa ukusetshenziswa kwayo kwezinye izinkambu. Ukuze kuxazululwe le nkinga, ukufakwa kwe-ammonium polyphosphate (APP) njengesivimbeli somlilo ku-PP kuye kwafundwa kabanzi.

I-Ammonium polyphosphate, uhlobo lwe-intumescent flame retardant, ifakwa ku-PP ukuze kuthuthukiswe ukumelana kwayo nomlilo. Lapho i-PP ene-APP ivezwa emazingeni okushisa aphezulu ngesikhathi somlilo, i-ammonium polyphosphate iyabola futhi ikhiphe i-ammonia, enciphisa ukugcwala kwamagesi avuthayo akhiqizwa ngesikhathi somlilo. Le nqubo inciphisa amandla okushisa futhi yehlisa ukusabalala kwamalangabi.

Ngaphezu kwalokho, ikhono lokwenza i-char le-ammonium polyphosphate lisiza ekwakheni ungqimba lwe-char oluzinzile noluvikelayo ebusweni bezinto ze-PP lapho luvezwa ekushiseni noma elangeni. Lolu ngqimba lwe-char lusebenza njengesivikelo, luvikela i-PP engaphansi ekushiseni futhi lunciphise ukukhishwa kwamagesi avuthayo, ngaleyo ndlela luthuthukise izakhiwo ezivimbela umlilo zezinto ze-PP.

Ngamafuphi, ukungezwa kwe-ammonium polyphosphate ku-PP akugcini nje ngokunciphisa ukusha kwezinto ngokunciphisa amagesi avuthayo kodwa futhi kukhuthaza ukwakheka kwesendlalelo se-char esivikelayo, ngaleyo ndlela kuthuthukiswe ukumelana nomlilo okuphelele kwamapulasitiki e-PP. Lokhu kwenza i-PP ene-ammonium polyphosphate ibe inketho efiselekayo yokusetshenziswa lapho ukuphepha komlilo kubaluleke kakhulu.

I-Taifeng Flame retardant TF-241 iyinhlanganisela ye-APP II enekhono eliphezulu lokunciphisa amalangabi ku-PP kanye ne-HDPE.
