Aluminium Diethyl Phosphinate

Aluminium diethyl phosphonate yog ib qho ua tau zoo thiab ib puag ncig tus phooj ywg organic phosphonate nplaim retardant, tshwm li dawb, dawb - ntws hmoov. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv qhov zoo tshaj plaws thermal stability thiab ib qho tshwj xeeb phosphorus - aluminium synergistic nplaim retardancy mechanism.

Nrog rau qhov pib decomposition kub siab tshaj 300 degree, cov khoom no tiv taus qhov siab -kub ntawm engineering plastics xws li polyamide thiab polyester, ua kom muaj kev ruaj ntseg thiab cov khoom zoo li. Lub phosphorus-aluminium system nyob rau hauv nws cov molecules ntes cov dawb radicals nyob rau hauv cov roj theem los cuam tshuam cov tshuaj tiv thaiv kab mob, thaum ib txhij txhawb kev tsim ntawm ib tug ntom, insulating char txheej nyob rau hauv lub condensed theem, yog li ua tau zoo heev nplaim retardancy. Qhov kev ua haujlwm biphasic no ua rau muaj kev ua tau zoo ntawm kev thauj khoom qis, ua ke nrog cov pa luam yeeb tsawg thiab cov yam ntxwv tsis muaj tshuaj lom, ua tau raws li cov kev cai ntawm ib puag ncig ntsuab.

Hauv cov ntawv thov yas engineering, ADEP muaj qhov cuam tshuam tsawg kawg nkaus ntawm cov khoom siv hauv cov khoom siv matrix. Hauv cov tshuab xws li PA6, PA66, PBT, PET, thiab epoxy resins, ib txwm 15-25% kev thauj khoom ua kom cov ntaub ntawv ua tiav UL94 V-0 nplaim taws retardancy thaum zoo khaws cia lub substrate lub zog txhua yam, hluav taws xob rwb thaiv tsev, thiab taug qab cov khoom siv hluav taws xob thiab hluav taws xob tseem ceeb. Tsis tas li ntawd, nws yog tsim rau textile coatings thiab tshwj xeeb fibers, enabling txoj kev loj hlob ntawm cov nplaim taws-retardant fabrics.

Hauv cov ntsiab lus, aluminium diethylphosphinate, los ntawm nws cov txheej txheem sib koom ua ke, muab cov nplaim hluav taws zoo tiv thaiv kev tiv thaiv thaum kawg khaws cov khoom zoo ntawm cov ntaub ntawv polymeric. Nws sawv cev rau qhov zoo tshaj plaws nplaim retardant tov rau siab -kawg engineering applications.

Nyob rau hauv siab -kub nylon systems, qhov sib ntxiv ntawm kwv yees li 10% los ntawm qhov hnyav ntawm ADP yog txaus kom ua tiav UL 94 V-0 nplaim retardant ntsuam xyuas rau cov ntaub ntawv nrog thicknesses ntawm 1.6mm thiab 0.8mm. Vim muaj kev hloov pauv hauv hom polymer substrate, kev ua tsis tau, thiab iav fiber ntau ntxiv piv, tus nqi ntawm ADP siv hauv cov khoom siv tiag tiag tuaj yeem hloov kho raws li kev ua haujlwm tshwj xeeb.

Ua ntej ntxiv ADP, lub polymer substrate yuav tsum tau ua ntej- qhuav raws li tus txheej txheem txheej txheem. Nws raug nquahu kom tswj cov substrate noo noo cov ntsiab lus rau cov qauv hauv qab no: siab -kub nylon noo noo yuav tsum tsawg dua 0.1% los ntawm qhov hnyav, PBT cov ntsiab lus noo noo yuav tsum tsawg dua 0.05% los ntawm qhov hnyav, thiab PET cov ntsiab lus noo noo yuav tsum tsawg dua 0.005% los ntawm qhov hnyav. ADP nws tus kheej tsis tas yuav ua ntej- ziab. Txawm li cas los xij, yog tias cov txheej txheem tsim khoom muaj cov cai nruj rau tag nrho cov dej noo, ADP tuaj yeem ua ntej- ziab, piv txwv li, los ntawm ziab ntawm 120℃rau 4 teev.

ADP yog sib xws nrog cov pa sib xyaw thiab ua cov txheej txheem rau cov ntaub ntawv hmoov; cov txheej txheem tshwj xeeb ntxiv tuaj yeem txiav txim siab raws li cov xwm txheej tsim khoom tiag tiag. Thaum lub sij hawm ua, nws yog ib qho tsim nyog los xyuas kom meej tias tag nrho cov Cheebtsam yog uniformly dispersed nyob rau hauv lub system, thiab nyob rau tib lub sij hawm, lub polymer yaj kub yuav tsum nruj me ntsis tswj thiab yuav tsum tsis txhob ntau tshaj 350 degree.

1. Thaum siv, tsis txhob nqus cov plua plav lossis kev sib cuag ntawm daim tawv nqaij thiab qhov muag.
2. Ua haujlwm hauv qhov dej - qhov chaw muaj cua thiab hnav cov khoom tiv thaiv tus kheej tsim nyog, xws li hnab looj tes thiab looj tsom iav.
3. Thaum lub sij hawm cia thiab tuav, tsis txhob sib cuag nrog cov oxidizers muaj zog los yog acids kom tsis txhob muaj kev phom sij.
