I-Ammonium polyphosphate (i-APP) iyinhlanganisela esetshenziswa kakhulu ye-inorganic, eyaziwa kakhulu ngendima yayo njengesinqamuleli somlilo kanye nomanyolo. Izakhiwo zayo eziyingqayizivele ziyenza ibe yingxenye ebalulekile ekusetshenzisweni okuhlukahlukene, okuhlanganisa amapulasitiki, izindwangu, nezindwangu. Ukuqonda ukuzinza kokushisa kwe-ammonium polyphosphate kubalulekile ukuze isetshenziswe ngempumelelo, ikakhulukazi ezindaweni ezinezinga lokushisa eliphezulu.
Ukucekelwa phansi kwe-ammonium polyphosphate ngokuvamile kuqala emazingeni okushisa aphakeme, ngokuvamile azungeze ama-200 kuya ku-300 degrees Celsius (392 kuya ku-572 degrees Fahrenheit). Kulawa mazinga okushisa, inhlanganisela ibhekana nochungechunge lwezinguquko zamakhemikhali ezingaholela ekukhululweni kwe-ammonia ne-phosphoric acid. Njengoba izinga lokushisa likhuphuka kakhulu, ikakhulukazi ngaphezu kuka-300 degrees Celsius, inqubo yokuwohloka iyashesha, okuholela ekwephuleni kwesakhiwo se-polymeric ye-APP.
Ukuwohloka okushisayo kwe-ammonium polyphosphate kungathonywa izici eziningana, okuhlanganisa isisindo sayo samangqamuzana, ukuba khona kwezithasiselo, kanye nokwakheka okuqondile okusetshenzisiwe. Isibonelo, i-APP enesisindo esiphansi se-molecular ivamise ukwehla emazingeni okushisa aphansi uma kuqhathaniswa nokuhluka okuphezulu kwesisindo se-molecular. Ukwengeza, ukuba khona kwezinye izinto ekwakhekeni okuyinhlanganisela kungathuthukisa noma kuvimbele inqubo yokuwohloka, kuye ngezici zazo ezishisayo nokusebenzisana ne-APP.
Esinye sezici ezibalulekile zokuziphatha okushisayo kwe-ammonium polyphosphate indima yayo njengesinqamuleli somlilo. Uma ichayeke ekushiseni, i-APP ingakhulula amagesi angashi, ancibilikisa umhwamuko ovuthayo futhi asize ukucindezela ukusha. Le ndawo ibaluleke kakhulu ezicelweni lapho ukuphepha emlilweni kuyinkinga. Kodwa-ke, ukusebenza kahle kwe-APP njengesinqamuleli somlilo kuboshelwe eduze nokuzinza kwayo okushisayo. Uma i-APP yehlisa isithunzi ngokushesha okukhulu, ingase inganikezi izinga elifiswayo lokuvikela.
Ngaphezu kwalokho, imikhiqizo yokuwohloka kwe-ammonium polyphosphate nayo ingaba nomthelela emvelweni nempilo yabantu. Ukukhishwa kwe-ammonia, ngokwesibonelo, kungaba nomthelela ekungcolisweni komoya futhi kungase kubangele izingozi zempilo uma uhogelwe ngenani elikhulu. Ngakho-ke, ukuqonda izinga lokushisa lokuwohloka kanye nokukhishwa kwamagesi okulandelayo kubalulekile ukuze kuhlolwe ukuphepha nomthelela wemvelo wemikhiqizo equkethe i-APP.
Ekusetshenzisweni okungokoqobo, kubalulekile ukucabangela izimo zokusebenza kanye namandla okuwohloka kokushisa lapho usebenzisa i-ammonium polyphosphate. Abakhiqizi bavame ukwenza ukuhlaziya okushisayo, okufana nokuhlaziywa kwe-thermogravimetric (TGA), ukuze banqume amazinga okushisa athile okonakaliswa kanye nokuthuthukisa ukwakheka kokuzinza nokusebenza.
Sengiphetha, i-ammonium polyphosphate iqala ukuwohloka emazingeni okushisa angaba ngu-200 kuya ku-300 degrees Celsius, nokuwohloka okukhulu okwenzeka emazingeni okushisa aphezulu. Ukuzinza kwayo okushisayo kuyisici esibalulekile ekusebenzeni kwayo njengesinqamuleli somlilo kanye nokusetshenziswa kwayo ngokuphelele ezinhlelweni ezahlukahlukene. Ukuqonda lezi zakhiwo ezishisayo akusizi nje kuphela ekwakhiweni kwemikhiqizo ephephile nesebenza ngempumelelo kodwa futhi kuqinisekisa ukuhambisana nemithetho yezemvelo kanye nezempilo. Njengoba ucwaningo luqhubeka, ukuqonda okwengeziwe ngokuziphatha okushisayo kwe-ammonium polyphosphate kuzothuthukisa ukusetshenziswa kwayo kanye namaphrofayili okuphepha embonini.
I-Sichuan Taifeng New Flame Retardant Co., Ltdingumkhiqizi oneminyaka engama-22 yesipiliyoni esikhethekile ekukhiqizeni i-ammonium polyphosphate retardants flame, imikhiqizo yethu ithunyelwa kabanzi phesheya kwezilwandle.
Omele yethu i-flame retardantTF-201i-eco-friendly futhi iyonga, inokusebenza okuvuthiwe emigqonyeni ye-itumescent, i-textile back coating, ipulasitiki, ukhuni, ikhebula, izinto zokunamathisela kanye negwebu le-PU.
Uma udinga ukwazi ulwazi olwengeziwe, sicela usithinte.
