I-ammonium polyphosphate isebenza kanjani kanye ne-melamine kanye ne-pentaerythritol ezimbozweni ze-intumescent?

Ezimbozweni ezingashi, ukusebenzisana phakathi kwe-ammonium polyphosphate, i-pentaerythritol, ne-melamine kubalulekile ekufezeni izakhiwo ezifiselekayo zokumelana nomlilo.

I-Ammonium polyphosphate (APP) isetshenziswa kabanzi njengesivimbeli somlilo ezinhlotsheni ezahlukene, okuhlanganisa nezingubo ezingashi. Uma ibekwe emazingeni okushisa aphezulu, i-APP ikhipha i-phosphoric acid, esabela kuma-free radicals akhiqizwa ngesikhathi senqubo yokushisa. Lokhu kusabela kuholela ekwakhekeni kwengqimba ye-char eqinile nevikelayo, esebenza njengesithiyo sokuvimbela ukushisa nokudluliswa komoya-mpilo, ngaleyo ndlela yehlisa ukusabalala kwamalangabi.

I-Pentaerythritol iyinhlanganisela ye-polyol esebenza njengomthombo wekhabhoni kanye ne-ejenti yokusha. Iyabola uma ibhekene nokushisa, ikhiqize amakhemikhali aguquguqukayo njenge-carbon dioxide kanye nomhwamuko wamanzi. Lawa makhemikhali aguquguqukayo anciphisa ukugcwala komoya-mpilo futhi avimbele ukusabela kokushisa, kuyilapho insalela yekhabhoni esele yakha ungqimba lwe-char oluzinzile oluvikela i-substrate ekudlulisweni kokushisa okwengeziwe.

I-Melamine, inhlanganisela ecebile nge-nitrogen, inegalelo ezimpahleni zokumboza ezingashi. Uma i-melamine ishiswa, ikhipha igesi ye-nitrogen, edlala indima ebalulekile ekucindezelweni komlilo. I-nitrogen ekhishwe iyasiza ekususeni umoya-mpilo, inciphise umoya-mpilo ozungeze amalangabi, ngaleyo ndlela ivimbele inqubo yokusha.

Ndawonye, ​​ukusebenzisana phakathi kwalezi zinto kuhlanganisa imiphumela ye-phosphorus, i-carbon, kanye ne-nitrogen ukuze kuthuthukiswe ukumelana nomlilo kwezimbozo. I-ammonium polyphosphate isebenza njengesivimbeli somlilo, yakha ungqimba lwe-char oluvikelayo. I-Pentaerythritol inegalelo ekwenzeni i-carbonization, ikhiqize i-char eyengeziwe yokuvikela ekushiseni. Ekugcineni, i-melamine ikhipha igesi ye-nitrogen ukuze idale umoya ocindezela umlilo. Ngokusebenza ngokubambisana, lezi zinto ezintathu zibambezela ngempumelelo ukusha futhi zehlise izinga lokusabalala komlilo, okwenza izimbozo ezingashisi umlilo ziphephe futhi zivikeleke kangcono ezingozini zomlilo.

I-Shifang Taifeng New Flame Retardant Co., Ltdungumkhiqizi onolwazi lweminyaka engama-22 ogxile ekukhiqizweni kwe-ammonium polyphosphate flame retardants, ama-prouducts ethu athunyelwa kabanzi kwamanye amazwe.

I-retardant yethu yomlilo emeleI-TF-201ilungele imvelo futhi iyonga, inokusetshenziswa okuvuthiwe ekumbozweni kwe-intumescent, ekumbozweni kwendwangu ngemuva, epulasitikini, okhunini, ekhebula, ezinamathelayo kanye ne-PU foam.

Uma udinga ukwazi ulwazi olwengeziwe, sicela usithinte.
