Silane Coupling Agents For Aluminium

I-Silane coupling agents isetyenziswa ngokuqhelekileyo kunyango lomphezulu we-aluminium ukuphucula ukudibanisa kunye nokubambelela kwezinye izinto ezifana neepolymers, iingubo okanye ezinye izinyithi.Iimolekyuli ze-Silane ziqulethe amaqela asebenzayo asebenzayo anokuthi adibanise ngokudibeneyo kumphezulu we-aluminium, kunye namaqela e-hydrophobic eziphilayo anokuthi adibanise iimolekyuli zezinto eziphilayo ezinokuthi ziboshwe.

Ezinye ezisetyenziswa ngokuqhelekileyo ii-aluminosilane coupling agents ziquka:

- I-Aminopropyltriethoxysilane (APTES): Le silane inamaqela e-amine anokumelana ne-carboxylic okanye amanye amaqela aneasidi kumphezulu we-polymer ukwenza i-covalent bonds eyomeleleyo.I-APTES iqhele ukusetyenziselwa ukudibanisa i-aluminiyam kwi-polyethylene, i-polypropylene okanye ezinye iiplastiki.

- I-Methacryloxypropyltrimethoxysilane (MPS): Le silane inokusebenza kwe-methacrylate kwaye ingenziwa ipolymerized nge-acrylic monomers okanye amanye amaqela e-vinyl ukwenza iibhondi zeekhemikhali ezomeleleyo.I-MPS iqhele ukusetyenziselwa ukubopha i-aluminium kwi-acrylics, i-epoxies, okanye ezinye iipolymers ezisekelwe kwi-vinyl.

- I-Glycidoxypropyltrimethoxysilane (GPTMS): Le silane inokusebenza kwe-epoxy enokungena kwiimpendulo zokuvula i-ring kunye namaqela e-hydroxyl okanye ezinye ii-nucleophiles ukwenza i-covalent bonds.I-GPTMS iqhele ukusetyenziselwa ukudibanisa i-aluminiyam kwi-polyurethanes, i-epoxies, okanye ezinye izinto ezinamaqela e-hydroxyl asebenzayo.
