Uma ucabangela into evimbela ilangabi engcono kakhulu ye-polypropylene, ukukhetha phakathi kwe-aluminium hydroxide ne-ammonium polyphosphate kuyisinqumo esibalulekile esithinta ngqo ukumelana nomlilo kanye nokusebenza kwemikhiqizo esekelwe ku-polypropylene.
I-aluminium hydroxide, eyaziwa nangokuthi i-alumina trihydrate, iyisivimbeli somlilo esisetshenziswa kabanzi esaziwa ngezakhiwo zayo ezinhle kakhulu zokuvimbela umlilo kanye nokuhambisana ne-polypropylene. Uma ivezwa emazingeni okushisa aphezulu, i-aluminium hydroxide ikhipha umhwamuko wamanzi, okusiza ukupholisa izinto futhi kuncishiswe amagesi avuthayo, ngaleyo ndlela kuncishiswe ingozi yokushisa futhi kwehliswe ukusabalala kwamalangabi. Le ndlela ithuthukisa ngempumelelo ukumelana nomlilo kwe-polypropylene ngaphandle kokuphazamisa izakhiwo zayo zemishini nezokushisa. Ngaphezu kwalokho, i-aluminium hydroxide ayinabo ubuthi futhi ingafakwa kalula ekwakhiweni kwe-polypropylene, okwenza kube ukukhetha okuthandwayo kwezicelo ezahlukahlukene.
Ngakolunye uhlangothi, i-ammonium polyphosphate ingenye into evame ukusetshenziswa njenge-flame retardant ye-polypropylene. Isebenza njenge-intumescent flame retardant, okusho ukuthi uma ibhekene nokushisa noma ilangabi, iyavuvukala futhi yakhe ungqimba lwe-char oluvikelayo oluvikela izinto futhi lunciphise ukukhishwa kwamagesi avuthayo. Lolu ngqimba lwe-char lusebenza njengesivikelo, luvimbela ngempumelelo ukusabalala kwamalangabi futhi lunikeze isivikelo somlilo kwi-polypropylene. I-Ammonium polyphosphate yaziwa ngokusebenza kwayo okuphezulu ekunciphiseni ukusha futhi ivame ukuthandwa lapho kukhethwa khona izinto ezivimbela ukusha umlilo ezivuthayo.
Uma kuqhathaniswa i-aluminium hydroxide kanye ne-ammonium polyphosphate njengezinto ezivimbela ilangabi ze-polypropylene, kunezinto eziningana ezibandakanyekayo. I-aluminium hydroxide ibaluleke kakhulu ngenxa yokungabi nobuthi kwayo, ukulula kokufakwa kwayo, kanye nokupholisa okuphumelelayo kanye nokuncibilikisa amagesi avuthayo. Okwamanje, i-ammonium polyphosphate iyaziwa ngezakhiwo zayo zokungena kanye nokusebenza kahle kakhulu ekwakheni ungqimba lwe-char oluvikelayo.
Ukukhetha phakathi kwalezi zinto ezivimbela umlilo kuncike ezidingweni ezithile zesicelo, kufaka phakathi izinga lokuvikela umlilo elifiswayo, ukuthobela imithetho, umthelela wemvelo, kanye nokucatshangelwa kwezindleko. Kokubili i-aluminium hydroxide kanye ne-ammonium polyphosphate kunikeza izinzuzo ezihlukile, futhi ukukhetha kufanele kusekelwe ekuhlolweni okuphelele kwalezi zici ukuqinisekisa ukusebenza okuhle kakhulu kokuvimbela umlilo kwemikhiqizo esekelwe ku-polypropylene.
Ekuphetheni, isinqumo phakathi kwe-aluminium hydroxide kanye ne-ammonium polyphosphate njengezithibi zomlilo ze-polypropylene sihilela ukuhlolwa ngokucophelela kwezakhiwo zazo kanye nokufaneleka kokusetshenziswa okuhlosiwe. Zombili lezi zithibi zomlilo zinikeza izinzuzo ezihlukile, futhi ukukhetha kufanele kwenziwe ngokusekelwe ezidingweni ezithile zokuvikela umlilo, izidingo zomthetho, kanye nezinhloso zokusebenza ezijwayelekile zemikhiqizo ye-polypropylene.
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.
