Izitayela Zokuthuthukiswa Nokusetshenziswa Kwe-Ammonium Polyphosphate Flame Retardant

1. Isingeniso

I-Ammonium polyphosphate(APP) iyisithako esivimbela ilangabi esisetshenziswa kabanzi embonini yezinto zesimanje. Isakhiwo sayo samakhemikhali esiyingqayizivele siyinika izakhiwo ezinhle kakhulu zokuvimbela ilangabi, okwenza kube yisithako esibalulekile ezintweni ezahlukahlukene ukuze kuthuthukiswe ukumelana nomlilo.

2. Izicelo

2.1 KuAmapulasitiki

Embonini yepulasitiki, i-APP ivame ukungezwa kuma-polyolefin afana ne-polyethylene (PE) kanye ne-polypropylene (PP). Isibonelo, emikhiqizweni esekelwe ku-PP efana nezingxenye zangaphakathi zezimoto, i-APP inganciphisa ngempumelelo ukusha kwepulasitiki. Iyabola emazingeni okushisa aphezulu, yakha ungqimba lwe-char oluvikelayo ebusweni bepulasitiki. Lolu ngqimba lwe-char lusebenza njengesivikelo esibonakalayo, luvimbela ukusabalala okuqhubekayo kokushisa nomoya-mpilo, ngaleyo ndlela luthuthukise ukusebenza okubambezelayo kwemikhiqizo yepulasitiki.

2.2 Ku-Izindwangu

Emkhakheni wezindwangu, i-APP isetshenziswa ekwelapheni izindwangu ezigcina ilangabi. Ingasetshenziswa ekotini, ezixubeni ze-polyester – ikotini, njll. Ngokufaka indwangu ngezixazululo eziqukethe i-APP – izixazululo, izindwangu eziphathwe kahle zingahlangabezana nezindinganiso zokuphepha zomlilo – ezidingekayo ekusetshenzisweni njengezindwangu, izindwangu ze-upholstery ezindaweni zomphakathi, kanye nezingubo zokusebenza. I-APP ebusweni bendwangu iyabola ngesikhathi sokusha, ikhiphe amagesi angashisi anciphisa ukugcwala kwamagesi angashisi akhiqizwa yindwangu, futhi ngesikhathi esifanayo, yakha ungqimba lwe-char ukuvikela indwangu engaphansi.

2.3 Ku-Ukugqoka

I-APP nayo iyisithako esibalulekile ekumbozweni komlilo - okubambezela umlilo. Uma ingezwa ekumbozweni kwezakhiwo, izakhiwo zensimbi, kanye nezinto zikagesi, ingathuthukisa izinga lokumelana nomlilo wezinto ezimboziwe. Ezakhiweni zensimbi, ukumbozwa komlilo - okubambezela umlilo nge-APP kungalibazisa ukukhuphuka kwezinga lokushisa kwensimbi ngesikhathi somlilo, kuvimbele ubuthakathaka obusheshayo bezakhiwo zensimbi futhi ngaleyo ndlela kunikeze isikhathi esengeziwe sokuphuma kanye nokulwa nomlilo.

3. Izitayela Zentuthuko

3.1 Okuphezulu – Ukusebenza Kahle kanye Nokuphansi – Ukulayisha

Enye yezindlela eziyinhloko zokuthuthukiswa ukuthuthukisa i-APP esebenza kahle kakhulu - ukubuyisa ilangabi, ukuze inani eliphansi le-APP likwazi ukufeza umphumela ofanayo noma ongcono - ukubuyisa ilangabi. Lokhu akugcini nje ngokunciphisa izindleko zezinto kodwa futhi kunciphisa umthelela ezimpahleni zokuqala zezinto ze-matrix. Isibonelo, ngokulawula usayizi wezinhlayiya kanye nokuguqulwa kwendawo, ukuhlakazeka kanye nokusebenza kabusha kwe-APP ku-matrix kungathuthukiswa, kuthuthukiswe ukusebenza kahle kwayo - ukubuyisa ilangabi.

3.2 Ubungane Emvelweni

Njengoba kugcizelelwa kakhulu ukuvikelwa kwemvelo, ukuthuthukiswa kwe-APP enobungani nemvelo kubalulekile. Ukukhiqizwa kwe-APP yendabuko kungase kuhilele ezinye izinqubo ezingabungani nemvelo kakhulu. Esikhathini esizayo, kuzohlolwa izinqubo zokukhiqiza ezinobungani nemvelo, njengokunciphisa ukusetshenziswa kwezinyibilikisi eziyingozi kanye nemikhiqizo enqubweni yokukhiqiza. Ngaphezu kwalokho, i-APP enokubola okungcono nayo iyathuthukiswa ukuze kuncishiswe umthelela wayo emvelweni ngemva kokuphela kwempilo yemikhiqizo.

3.3 Ukuthuthukiswa Kokuhambisana

Ukuthuthukisa ukuhambisana kwe-APP nezinto ezahlukene ze-matrix kungenye indlela ebalulekile. Ukuhambisana okungcono kungaqinisekisa ukusabalala okufanayo kwe-APP ku-matrix, okuzuzisa ukusebenzisa ngokugcwele izakhiwo zayo ezivimbela ilangabi. Ucwaningo luyenziwa ukuthuthukisa ama-coupling agents noma i-APP eguquliwe ebusweni ukuze kuthuthukiswe ukuhambisana kwayo nepulasitiki ehlukahlukene, izindwangu, kanye nezingubo, ukuze kuthuthukiswe ukusebenza okuphelele kwezinto ezihlanganisiwe.

4. Isiphetho

I-Ammonium polyphosphate, njengesivimbeli somlilo esibalulekile, inezinhlobo eziningi zokusetshenziswa kumapulasitiki, izindwangu, izembozo, nakweminye imikhakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe, iya phambili ekuqondeni kokusebenza kahle okuphezulu, ubungane bemvelo, kanye nokuhambisana okungcono, okuzoqhubeka nokwandisa ububanzi bokusetshenziswa kwayo futhi kudlale indima ebaluleke kakhulu ekuvimbeleni umlilo kanye nokuvikela ukuphepha esikhathini esizayo.
