Indima Ephambili yeI-Ammonium Polyphosphatekwi-Fire Retardant Coatings: Iziphumo ze-Synergistic kunye ne-Melamine kunye ne-Pentaerythritol
I-Ammonium polyphosphate(APP) isebenza njengecandelo eliphambili ekuqulunqweni kwezinto zanamhlanjeiingubo ezithintela umlilo, inika ukhuseleko olukhethekileyo kwingozi yomlilo. Iimpawu zayo ezikhethekileyo, xa zidityaniswe nezinye izithako ezibalulekileyo ezifana ne-melamine kunye ne-pentaerythritol, zenza intsebenziswano enamandla ephucula kakhulu ukusebenza kokuthintela umlilo kwengubo.
Njengesixhobo esithintela ilangatye esiphambili,i-ammonium polyphosphateisebenza ngendlela enamacala amaninzi. Xa ichaphazeleka kubushushu obuphezulu, iyabola ize ikhuphe i-phosphoric acid, ethi emva koko idibane ne-substrate yenze umaleko we-char okhuselayo. Lo maleko we-char usebenza njengomqobo, uthintela ukutsha okungakumbi kunye nokudluliselwa kobushushu. Ukongeza, ukukhululwa kweegesi ezingatshiyo, ezifana ne-ammonia kunye nomphunga wamanzi, kunceda ekunciphiseni uxinzelelo lwe-oksijini olujikeleze izinto ezitshayo, nto leyo ecinezela ngakumbi amalangatye.
Nangona i-ammonium polyphateralone isebenza kakhulu ngokwayo, ukusebenza kwayo kunokuphuculwa ngakumbi ngokongeza i-melamine kunye ne-pentaerythritol. I-Melamine inegalelo ekwakhiweni komaleko we-char oqinileyo nozinzileyo ngokubonelela ngomxholo we-nitrogen owongezelelweyo. Le nitrogen ayinyusi nje kuphela ubungakanani begesi engatshiyo ekhutshwayo kodwa ikwakhuthaza ukudibanisa kwe-char, okwenza ukuba imelane nokuqhekeka.
Kwelinye icala, iPentaerythritol idlala indima ebalulekileyo ekuphuculeni iimpawu zomzimba zengubo ethintela umlilo. Njengeplastiki, iphucula ukuguquguquka kunye nokunamathela kwengubo, iqinisekisa ukugqunywa okungcono kunye nokuqina. Ngaphezu koko, ipentaerythritol isebenza njengomkhuthazi we-char, iququzelela ukwakheka komaleko we-char otyebileyo noqhubekayo okhusela ngokufanelekileyo izinto ezingaphantsi kwilangatye.
Indibaniselwano yokusebenzisana kwei-ammonium polyphosphate, i-melamine, kunye ne-pentaerythritol kwiingubo ezithintela umlilo ziphumela kwisisombululo sokukhusela umlilo esisebenza kakuhle nesithembekileyo. Olu hlobo lunamandla aluboneleli nje kuphela ngokuthintela umlilo okugqwesileyo kodwa lukwabonelela ngeempawu zomzimba eziphuculweyo, nto leyo eyenza ukuba lube lolona khetho lufanelekileyo kwiintlobo ngeentlobo zezicelo.
Isishwankathelo,i-ammonium polyphosphateIbonakala njengeyona nto iphambili kwiingubo ezithintela umlilo, kunye nemiphumo yayo emangalisayo yokusebenzisana kunye ne-melamine kunye ne-pentaerythritol ephucula ngakumbi ukusebenza kwayo. Olu dibaniso lwezithako luqinisekisa ukuba ingubo inika ukhuseleko olufanelekileyo kwiingozi zomlilo, ikhusela ubomi kunye nepropathi.
