I-Ammonium Polyphosphate (APP)
I-Ammonium Polyphosphate (APP) iyisinqamuleli somlilo esisetshenziswa kakhulu, sisetshenziswa kakhulu kumaleya avimbela umlilo. I-Intumescent fire retardant coating iyi-coat ekhethekile yokuvimbela umlilo. Umsebenzi wayo oyinhloko uwukwenza ungqimba lokuvikela ukushisa ngokusebenzisa igesi ebuyisela amalangabi ekhiqizwe ukunwetshwa ukuze kuvinjelwe ukusabalala komlilo futhi kuvinjwe umonakalo ezakhiweni lapho kuvela umlilo.
Isimiso
I-Ammonium polyphosphate isetshenziswa njengengxenye enkulu yokubuyisela amalangabi ezimbotsheni ze-intumescent retardant. I-Ammonium polyphosphate inezindawo ezinhle zokunqanda ilangabi. Lapho izinga lokushisa likhuphuka, lizobola likhiqize i-phosphoric acid negesi ye-ammonia. Le mikhiqizo ingakwazi ukukhipha amanzi emzimbeni ibe amalahle, ngaleyo ndlela ivimbele umoya-mpilo nokushisa, ngaleyo ndlela ikhiqize umphumela wokunqanda ilangabi. Ngesikhathi esifanayo, i-ammonium polyphosphate nayo iyanda. Uma ishisa futhi ibola, izokhiqiza inani elikhulu legesi, ukuze i-intumescent coating engenamlilo yakha ungqimba oluqinile lwekhabhoni olungashi, oluhlukanisa ngokuphumelelayo umthombo womlilo ekuthinteni futhi luvimbele umlilo ukuba ungasakazeki.
Izinzuzo
I-Ammonium polyphosphate inezinzuzo zokuzinza okuhle kokushisa, ukumelana namanzi nomswakama, okungeyona ubuthi futhi okungangcolisi imvelo, ngakho-ke isetshenziswa kabanzi emigqonyeni ye-intumescent engenamlilo. Inganezelwa kusisekelo sezinto zokumboza ezivimbela umlilo ukuze kwakhiwe uhlelo oluphelele lokuvimbela umlilo kanye nezinye izinto ezivimbela amalangabi, ama-binder nama-filler. Ngokuvamile, ukusetshenziswa kwe-ammonium polyphosphate emigqonyeni ye-intumescent ye-retardant inganikeza izici ezinhle kakhulu ze-flame retardancy kanye nezici zokunweba, futhi ivikele ngempumelelo ukuphepha kwezakhiwo nezakhiwo emlilweni.
Isicelo
Ngokwezinto ezahlukahlukene ezidinga ku-APP, Ukusetshenziswa kwe-ammonium polyphosphate enamathela kuboniswa ikakhulukazi ku:
1. I-Intumescent FR coating on indoor building steel structure.
2. I-textile back coating in amakhethini, i-black coating.
3. Ikhebula le-FR.
4. Okukhulu okusetshenziselwa ukwakhiwa, ukuhamba ngezindiza, ukumboza imikhumbi.
