Indima Evelele Ka-I-Ammonium Polyphosphateku-Fire Retardant Coatings: Imiphumela Yokubambisana ne-Melamine ne-Pentaerythritol
I-Ammonium polyphosphate(i-APP) isebenza njengengxenye ebalulekile ekwakhiweni kwesimanjeizembozo ezivimbela umlilo, inikeza isivikelo esiyingqayizivele ekusongelweni komlilo. Izakhiwo zayo eziyingqayizivele, uma zihlanganiswa nezinye izithako ezibalulekile njenge-melamine ne-pentaerythritol, zakha ukusebenzisana okunamandla okuthuthukisa kakhulu ukusebenza kokuvimbela umlilo kwengubo.
Njengesivimbeli somlilo esiyinhloko,i-ammonium polyphosphateisebenza ngendlela enezinhlangothi eziningi. Lapho ibhekene nokushisa okuphezulu, iyabola futhi ikhiphe i-phosphoric acid, bese isabela ne-substrate ukuze yakhe ungqimba lwe-char oluvikelayo. Lolu ngqimba lwe-char lusebenza njengesivikelo, luvimbela ukusha okuqhubekayo kanye nokudluliselwa kokushisa. Ngaphezu kwalokho, ukukhishwa kwamagesi angashi, njenge-ammonia kanye nomhwamuko wamanzi, kusiza ekunciphiseni ukugcwala komoya-mpilo ozungeze izinto ezivuthayo, okucindezela kakhulu amalangabi.
Nakuba i-ammonium polyphateralone isebenza kahle kakhulu ngokwayo, ukusebenza kwayo kungathuthukiswa kakhulu ngokufaka i-melamine ne-pentaerythritol. I-Melamine inegalelo ekwakhekeni kwengqimba ye-char eqinile futhi ezinzile ngokunikeza okuqukethwe okwengeziwe kwe-nitrogen. Le nitrogen ayikhulisi nje kuphela inani legesi engashisi ekhishwayo kodwa futhi ikhuthaza ukuxhumanisa kwe-char, okwenza imelane kakhulu nokuqhekeka.
Ngakolunye uhlangothi, i-Pentaerythritol idlala indima ebalulekile ekuthuthukiseni izakhiwo zomzimba zengubo evimbela umlilo. Njenge-plasticizer, ithuthukisa ukuguquguquka nokunamathela kwengubo, iqinisekisa ukumbozwa okungcono nokuqina. Ngaphezu kwalokho, i-pentaerythritol isebenza njengesikhuthazi se-char, ikhuthaza ukwakheka kwengqimba ye-char ejiyile futhi eqhubekayo evikela ngempumelelo izinto ezingaphansi emalangabini.
Inhlanganisela yokusebenzisana kwe-i-ammonium polyphosphate, i-melamine, kanye ne-pentaerythritol ezimbozweni ezivimbela umlilo kuphumela esixazululweni sokuvikela umlilo esisebenza kahle kakhulu nesithembekile. Lo mshini onamandla awugcini nje ngokuhlinzeka ngokuvimba umlilo okuhle kakhulu kodwa futhi unikeza izakhiwo zomzimba ezithuthukisiwe, okwenza kube ukukhetha okuhle kwezinhlelo zokusebenza ezahlukahlukene.
Ngokufigqiwe,i-ammonium polyphosphateIvelele njengomdlali ovelele ekugqokeni okuvimbela umlilo, ngemiphumela yayo emangalisayo yokusebenzisana ne-melamine ne-pentaerythritol ethuthukisa ukusebenza kwayo. Lokhu kuhlanganiswa kwezithako kuqinisekisa ukuthi ukugqoka kunikeza isivikelo esifanele ezingozini zomlilo, kuvikele kokubili izimpilo kanye nempahla.
