Ingcaciso yeMveliso

I-4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, inombolo ye-CAS 19900-72-2, isetyenziswa njenge-chain extender ye-polyurethane elastomers kwaye njenge-ejenti yokuphilisa i-epoxy resin ukuphucula iipropati ze-mechanical kunye ne-dynamic zemveliso. I-MED ingasetyenziswa njenge-compound ehamba phambili ye-polyimides kwaye njenge-intermediation ye-organic synthesis.

Ifanelekile kakhulu kwi-casting polyurethane (CPU), i-thermoplastic polyurethane (TPU), i-RIM elastomers kunye ne-spray polyurea kwintsimi ye-polyurethane. I-MED ikwasebenza nakwizinto zokucoca, zokulungiselela kunye nezokukhusela iikhemikhali kwintsimi ye-epoxy resin. I-MED isetyenziswa ekuhlanganiseni ii-prepolymers, kubandakanya i-polyether kunye ne-polyester.

I-MED sisisombululo esifanelekileyo kwiimveliso ezigqityiweyo ezifuna umbala okhanyayo kunye nokulwa nokwaluphala. I-MED ingafakwa kunye nezinye izinto zokunyanga ezifana ne-amine (i-compound) ukuze ihlangabezane neempawu zomzimba ezingcono.

I-MED kunye ne-MOCA zombini zii-amine-type agents eziphilisayo. Nangona kunjalo, i-MED ayingcolisi kakhulu indalo kwaye ayingcolisi kangako xa ithelekiswa ne-MOCA. I-MED ingathatha indawo ye-MBOEA kunye ne-HQEE kwiimveliso ze-PU, nokuba yi-CPU (casting polyurethane) okanye i-TPU (thermoplastic polyurethane). Njenge-MOCA, ii-elastomers zohlobo lwe-MED zinokumelana okuhle kobushushu okufuna amandla xa usebenza ngaphezulu kwe-120℃.

Isicelo

I-MED/MMEA sisixhobo sokwandisa i-diamine chain kunye ne-agent yokupholisa. Ngenxa yemithetho engqongqo yokusebenzisa i-MOCA, i-MED enobuhlobo nokusingqongileyo, engangcoliswanga lolunye ukhetho olufanelekileyo olusetyenziswa kwiintlobo ngeentlobo zezicelo. Ii-polyurethanes ze-MED-base zinokuguquguquka kwaye zikhululekile ukuyila, zineempawu ezinamandla aphezulu ngelixa zigcina ukuthamba kwazo. Iimveliso ezigqityiweyo zohlobo lwe-MED zihlala ixesha elide kwaye ziyamelana nokuchasana okuzivumela ukuba zilungele ukusetyenziswa okunzima, njengee-bumper pads, ii-casters, ii-rollers, amatayara e-forklift, izinto zomatshini njalo njalo. Ngaphezu koko, i-MED ingasetyenziswa njenge-agent ye-bridge kwi-semi-conductor kwaye njenge-agent yokupholisa kwi-epoxy kunye ne-polyurea.
