I-Ammonium polyphosphate (APP) iyisithambisi somlilo esisetshenziswa kabanzi kanye nomanyolo, owaziwa ngokusebenza kwayo kahle ekuqiniseni ukumelana nomlilo ezintweni ezahlukahlukene. Enye yezindlela ezibalulekile zokuhlaziya ezisetshenziswa ukuqonda izakhiwo zokushisa ze-APP yi-Thermogravimetric Analysis (TGA). I-TGA ilinganisa ushintsho ebuningini bento njengoba ishiswa, ipholiswa, noma igcinwe ekushiseni okungaguquki, ihlinzeka ngemininingwane ebalulekile ngokuzinza kwayo ekushiseni, ukuziphatha kokubola, kanye nokusebenza kwayo konke ekusetshenzisweni.
Ukubaluleka kwe-TGA ekufundweni kwe-ammonium polyphosphate akunakuphikiswa. Okokuqala nokubaluleke kakhulu, i-TGA iyasiza ekunqumeni ukuzinza kokushisa kwe-APP. Ukuqonda izinga lokushisa lapho i-APP ihlala izinzile kubalulekile ekusetshenzisweni kwayo ekubambezelekeni komlilo. Uma i-APP ibola emazingeni okushisa aphansi, ingase ingasebenzi kahle ekuvikeleni izinto emlilweni, njengoba izolahlekelwa yizimfanelo zayo zokuvimbela umlilo ngaphambi kokuba izinto ngokwazo zifinyelele ekushiseni okubucayi. I-TGA ivumela abacwaningi ukuthi bathole ukuqala kokubola, okubenza bakwazi ukwenza ngcono ukwakheka kwezicelo ezithile.
Ngaphezu kwalokho, i-TGA inikeza ukuqonda ngemikhiqizo yokubola kwe-APP. Ukuwohloka kokushisa kwe-ammonium polyphosphate kungaholela ekukhishweni kwamagesi ahlukahlukene, okuhlanganisa i-ammonia ne-phosphoric acid. Ngokuhlaziya ukulahlekelwa okukhulu ezigabeni ezahlukene zokushisa, abacwaningi bangabona amazinga athile okushisa lapho la magesi ekhishwa khona. Lolu lwazi lubalulekile ekuqondeni indlela yokuphelelwa amandla komlilo, njengoba ukukhishwa kwamagesi angashi kunganciphisa umusi ovuthayo futhi kunciphise ukusha kwezinto.
Esinye isici esibalulekile se-TGA yindima yayo ekwakhiweni kwezinhlanganisela ezisekelwe ku-APP. Ezinhlelweni eziningi, i-APP ihlanganiswa nezinye izinto ukuze ithuthukise ukusebenza kwayo. I-TGA ingasetshenziswa ukuhlola ukuhambisana nokuzinza kwalezi zinhlanganisela ngaphansi kokucindezeleka kokushisa. Ngokuhlola ukuziphatha kokushisa kwezinto ezihlanganisiwe, abacwaningi banganquma izilinganiso ezifanele ze-APP kwezinye izingxenye, baqinisekise ukuthi umkhiqizo wokugcina ugcina izakhiwo zawo ezivimbela umlilo ngenkathi ufeza izici ezifiselekayo zemishini nezokushisa.
Ngaphezu kwalokho, i-TGA ingasiza ekulawuleni ikhwalithi ngesikhathi sokukhiqizwa kwe-ammonium polyphosphate. Ngokusungula iphrofayili yokushisa ye-APP, abakhiqizi bangaqapha ukuhambisana kanye nekhwalithi yemikhiqizo yabo. Ukuphambuka ekuziphatheni kokushisa okusunguliwe kungabonisa izinkinga enqubweni yokukhiqiza, njengokusabela okungaphelele noma ukungcola, okungabeka engcupheni ukusebenza kahle kwe-flame retardant.
Ekuphetheni, ukubaluleka kwe-TGA ekufundweni kwe-ammonium polyphosphate kusekukwazini kwayo ukunikeza ulwazi olubalulekile mayelana nokuzinza kokushisa, ukuziphatha kokubola, kanye nokuhambisana nezinye izinto. Le ndlela yokuhlaziya ayigcini nje ngokuthuthukisa ukuqonda kwethu ukusebenza kwe-APP njengento evimbela ilangabi kodwa futhi idlala indima ebalulekile ekuthuthukisweni nasekulawulweni kwekhwalithi yemikhiqizo esekelwe ku-APP. Njengoba izimboni ziqhubeka nokufuna izixazululo zokuphepha komlilo ezisebenzayo, ukuqonda okutholwe ku-TGA kuzohlala kubaluleke kakhulu ekuthuthukiseni ukusetshenziswa kwe-ammonium polyphosphate emikhakheni eyahlukahlukene.
I-Sichuan 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-241ilungele imvelo futhi iyonga, inokusetshenziswa okuvuthiwe ku-PP, PE, HEDP.
Uma udinga ukwazi ulwazi olwengeziwe, sicela usithinte.
