Polypropylene yog cov khoom siv yas uas muaj cov cua kub zoo, tiv thaiv corrosion thiab cov khoom siv kho tshuab, yog li nws tau siv dav hauv kev lag luam thiab lub neej txhua hnub. Txawm li cas los xij, vim nws cov khoom siv hluav taws xob, cov nplaim hluav taws yuav tsum tau ntxiv los txhim kho nws cov nplaim hluav taws xob. Cov hauv qab no yuav qhia txog qee cov nplaim hluav taws uas tuaj yeem siv rau polypropylene.
Aluminium triphosphate: Aluminium triphosphate yog ib qho uas nquag siv halogen-dawb nplaim retardant uas tuaj yeem txhim kho cov nplaim hluav taws xob ntawm polypropylene. Nws tuaj yeem tso cov phosphorus oxides ntawm qhov kub thiab txias los tsim cov txheej txheem tiv thaiv kom tsis txhob kis cov pa oxygen thiab cua sov, yog li ua tiav cov nplaim hluav taws kub.
Aluminium hydroxide: Aluminium hydroxide yog ib qho tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj corrosive nplaim retardant uas tuaj yeem txhim kho cov nplaim hluav taws xob zoo ntawm polypropylene. Nws decomposes ntawm qhov kub siab kom tso dej vapor, nqus cua sov, thiab txo qhov kub thiab txias tso tawm ntawm polypropylene.
Aluminium silicate: Aluminium silicate yog cov nplaim hluav taws tsis muaj halogen uas tuaj yeem txhim kho cov nplaim hluav taws kub ntawm polypropylene. Nws tuaj yeem decompose ntawm qhov kub thiab txias kom tso dej vapor thiab silicon dioxide los tsim cov txheej txheem tiv thaiv kom tsis txhob kis cov pa oxygen thiab cua sov, yog li ua tiav cov nplaim hluav taws kub.
Ammonium polyphosphate yog phosphorus-nitrogen nplaim retardant nrog zoo nplaim retardant zog thiab thermal stability, thiab yog dav siv nyob rau hauv cov ntaub ntawv polypropylene. Ammonium polyphosphate tuaj yeem decompose ntawm qhov kub thiab txias kom tso tawm phosphorus oxides thiab ammonia, tsim cov pa roj carbon txheej los tiv thaiv kev sib kis ntawm oxygen thiab cua sov, yog li txhim kho cov nplaim hluav taws xob ntawm polypropylene. Tsis tas li ntawd, ammonium polyphosphate kuj muaj cov yam ntxwv ntawm cov tshuaj toxicity tsawg, tsis tshua muaj corrosiveness thiab ib puag ncig tus phooj ywg, ua rau nws zoo tagnrho polypropylene nplaim retardant.
Hauv kev lag luam, ammonium polyphosphate yog siv dav hauv cov khoom siv hluav taws xob hluav taws xob rau polypropylene, xws li cov khoom siv hluav taws xob, cov khoom siv hauv tsev, cov khoom siv tsheb thiab lwm yam. Nws cov nplaim hluav taws zoo heev thiab cov yam ntxwv tiv thaiv ib puag ncig tau raug lees paub thiab siv. Nyob rau tib lub sijhawm, raws li tib neeg cov kev xav tau rau kev tiv thaiv ib puag ncig thiab kev nyab xeeb kev ua haujlwm nce, ammonium polyphosphate, raws li cov nplaim hluav taws tsis muaj halogen, yuav ua lub luag haujlwm tseem ceeb hauv cov khoom siv polypropylene.
Feem ntau, polypropylene, raws li cov khoom siv yas, yuav tsum tau ntxiv cov nplaim hluav taws xob los txhim kho nws cov nplaim hluav taws. Aluminium triphosphate, aluminium hydroxide, aluminium silicate, thiab lwm yam yog cov nplaim hluav taws kub uas tuaj yeem siv rau polypropylene, thiab ammonium polyphosphate, ua cov nplaim hluav taws xob phosphorus-nitrogen, muaj cov ntawv thov dav dav hauv polypropylene.
