I-Ammonium Polyphosphate (i-APP)
I-Ammonium Polyphosphate (APP) iyisivikelo somlilo esisetshenziswa kakhulu, esisetshenziswa kabanzi ezimbozweni ezivimbela umlilo ezingaphakathi. Isivikelo esivimbela umlilo esingaphakathi siyisivikelo esikhethekile esivimbela umlilo. Umsebenzi wayo oyinhloko ukwakha ungqimba lokuvikela ukushisa ngegesi evimbela umlilo ekhiqizwa ukwanda ukuze kuvinjelwe ukusabalala komlilo nokuvimbela umonakalo ezakhiweni lapho kuvela umlilo.
Isimiso
I-Ammonium polyphosphate isetshenziswa njengesivimbeli esiyinhloko somlilo ezimbozweni ezivimbela umlilo ezingaphakathi. I-Ammonium polyphosphate inezakhiwo ezinhle zokuvimbela umlilo. Lapho izinga lokushisa likhuphuka, lizobola ukuze likhiqize i-phosphoric acid kanye negesi ye-ammonia. Le mikhiqizo ingakhipha amanzi ezintweni eziphilayo zibe amalahle, ngaleyo ndlela ifake umoya-mpilo nokushisa, ngaleyo ndlela ikhiqize umphumela wokuvimbela umlilo. Ngesikhathi esifanayo, i-ammonium polyphosphate nayo ibanzi. Uma ishiswa futhi ibola, izokhiqiza inani elikhulu legesi, ukuze isivimbeli esivimbela umlilo esingaphakathi sakha ungqimba lwekhabhoni oluqinile olungashi, oluhlukanisa ngempumelelo umthombo womlilo ekuthinteni futhi luvimbele umlilo ukuthi ungasabalali.
Izinzuzo
I-Ammonium polyphosphate inezinzuzo zokuzinza okuhle kokushisa, ukumelana namanzi nomswakama, ayinabo ubuthi futhi ayingcolisi imvelo, ngakho-ke isetshenziswa kabanzi ezimbozweni ezingashisi umlilo ezingaphakathi. Ingangezwa ezintweni eziyisisekelo zezingubo ezingashisi umlilo ukuze kwakheke uhlelo oluphelele lwezingubo ezingashisi umlilo kanye nezinye izinto ezingashisi umlilo, izihlanganisi kanye nezigcwalisi. Ngokuvamile, ukusetshenziswa kwe-ammonium polyphosphate ezimbozweni ezingashisi umlilo ezingaphakathi kunganikeza izici ezinhle kakhulu zokuvimbela umlilo kanye nokwanda, futhi kuvikele ngempumelelo ukuphepha kwezakhiwo nezakhiwo ezikumlilo.
Isicelo
Ngokwezidingo zezinto ezahlukene ku-APP, ukusetshenziswa kwe-ammonium polyphosphate ekumbozeni kubonakala kakhulu ku:
1. Isembozo se-Intumescent FR esakhiweni sensimbi esakhiwe ngaphakathi.
2. Ukufakwa kwendwangu ngemuva kwamakhethini, ukufakelwa kwendwangu ngaphandle kokukhanya.
3. Ikhebula le-FR.
4. Okukhulu okusetshenziselwa ukwakha, izindiza, ukugqoka ubuso bemikhumbi.
