Indima Evelele yeI-Ammonium PolyphosphateKu-Fire Retardant Coatings: I-Synergistic Effects nge-Melamine ne-Pentaerythritol
I-Ammonium polyphosphate(APP) isebenza njengengxenye esemqoka ekwakhiweni kwesimanjemanjeizingubo zokuvala umlilo, enikeza isivikelo esikhethekile ekusongelweni komlilo. Izakhiwo zayo eziyingqayizivele, uma zihlanganiswa nezinye izithako ezibalulekile ezifana ne-melamine ne-pentaerythritol, zakha i-synergy enamandla ethuthukisa kakhulu ukusebenza komlilo we-coating.
Njengesinqamuleli sokuqala somlilo,i-ammonium polyphosphateisebenza ngendlela enezinhlangothi eziningi. Lapho ibhekene nezinga lokushisa eliphezulu, iyabola futhi ikhiphe i-phosphoric acid, ebese isabela ne-substrate yakhe ungqimba lwe-char oluvikelayo. Lesi sendlalelo se-char sisebenza njengesithiyo, sivimbela ukuvutha okuqhubekayo nokudluliswa kokushisa. Ukwengeza, ukukhishwa kwamagesi angashi, njenge-ammonia nomhwamuko wamanzi, kusiza ukunciphisa ukugcwala komoyampilo endaweni evuthayo, kuqhubeke kucindezela amalangabi.
Nakuba i-ammonium polyphateralone isebenza kakhulu iyodwa, ukusebenza kwayo kungathuthukiswa ngokwengeziwe ngokufakwa kwe-melamine ne-pentaerythritol. I-Melamine inomthelela ekwakhekeni kwe-char layer enamandla kakhulu futhi ezinzile ngokuhlinzeka ngokuqukethwe kwe-nitrogen eyengeziwe. Le nitrogen ayigcini nje ngokukhuphula inani legesi engashi ekhishwayo kodwa futhi ikhuthaza ukuhlangana kwe-char, iyenze imelane nokuwohloka.
I-Pentaerythritol, ngakolunye uhlangothi, idlala indima ebalulekile ekuthuthukiseni izakhiwo ezibonakalayo ze-coating evimbela umlilo. Njenge-plasticizer, ithuthukisa ukuguquguquka nokunamathela kwe-coating, iqinisekisa ukumbozwa okungcono nokuqina. Ngaphezu kwalokho, i-pentaerythritol isebenza njengomgqugquzeli we-char, yenza kube lula ukwakheka kwe-char layer eqinile futhi eqhubekayo evikela ngempumelelo into engaphansi emalangabini.
Inhlanganisela ye-synergistic yei-ammonium polyphosphate, i-melamine, ne-pentaerythritol emigqeni evimbela umlilo iphumela kusixazululo esisebenza kahle kakhulu nesinokwethenjelwa sokuvikela umlilo. Laba abathathu abanamandla abahlinzeki nje ngokubambezeleka komlilo okuhle kakhulu kodwa futhi banikeza izakhiwo ezithuthukisiwe zomzimba, okuyenza ibe ukukhetha okuhle kwezinhlelo zokusebenza eziningi.
Ngokufigqiwe,i-ammonium polyphosphateigqama njengomdlali ovelele ezingubo ezivimba umlilo, nemiphumela yayo emangalisayo yokuhlangana nge-melamine ne-pentaerythritol ethuthukisa ukusebenza kwayo. Le nhlanganisela yezithako iqinisekisa ukuthi ukumbozwa kunikeza ukuvikeleka okuphelele ezingozini zomlilo, ukuvikela kokubili izimpilo kanye nempahla.
I-Sichuan Taifeng New Flame Retardant Co., Ltduchwepheshei-ammonium polyphosphateumkhiqizi eChina oneminyaka engama-22 yesipiliyoni. I-APP TF-201 ingumkhiqizo odumile futhi ovuthiwe owamukelwa yi-EU, India, Southeast Asia.
