4,4′-Methylenebis(2-ethyl-6-methylaniline) / MMEA CAS No. 19900-72-2
I-4,4'-Methylenebis (2-ethyl-6-methylaniline) / MMEA, inombolo ye-CAS 19900-72-2, isetyenziselwa i-chain extender ye-polyurethane elastomers kunye ne-agent ephilisa i-epoxy resin ukuphucula iimpawu zomatshini kunye neziguquguqukayo. yeemveliso. I-MED ingasetyenziselwa njengekhompawundi ehamba phambili ye-polyimides kunye nokudibanisa kwe-organic synthesis.
Ilungele ukuphosa i-polyurethane (CPU), i-polyurethane ye-thermoplastic (TPU), i-RIM elastomers kunye ne-spray polyurea kwintsimi ye-polyurethane. I-MED iyasebenza nakwi-processing, prepreg kunye neekhemikhali zokugquma i-anticorrosive kwintsimi ye-epoxy resin. I-MED isetyenziswe kwi-synthesis ye-prepolymers, kuquka i-polyether kunye ne-polyester.
I-MED sisisombululo esifanelekileyo kwiimveliso ezigqityiweyo ezifuna umbala okhanyayo kunye nokuchasana nokuguga. I-MED ingasetyenziswa kunye nezinye ii-amine-type-curing agents (i-compound) ukuhlangabezana neempawu ezingcono zomzimba.
I-MED kunye ne-MOCA zombini zi-amine-type arhente zokunyanga. Nangona kunjalo, i-MED i-eco-friendly kwaye ayingcolisi kangako xa kuthelekiswa ne-MOCA. I-MED inokuthi ithathe indawo ye-MBOEA kunye ne-HQEE kwiimveliso ze-PU, kungakhathaliseki ukuba i-CPU (i-polyurethane yokuphosa) okanye i-TPU (i-thermoplastic polyurethane). Ngokufana ne-MOCA, i-MED-type elastomers ibonakalisa ukumelana nobushushu obubalaseleyo obufuna ukusebenza ngaphezulu kwe-120 ℃.
I-MED/MMEA sisixokelelwano se-diamine esinevumba elimnandi kunye ne-arhente yokunyanga. Ngenxa yemigaqo engqongqo yokusebenzisa i-MOCA, i-MED eco-friendly, engangcoliswanga lolunye ukhetho olufanelekileyo olusebenzisa kwizicelo ezahlukeneyo. I-MED-base polyurethanes iyinto eguquguqukayo kunye nenkululeko yoyilo, kunye neempawu zamandla aphezulu ngelixa igcina ukuqina kwayo. Iimveliso ezigqityiweyo zohlobo lwe-MED zizinzileyo kwaye zixhathisa okwenza ukuba zilungele izicelo ezifunwayo, ezifana ne-bumper pads, i-casters, i-roller, i-forklift amathayi, amacandelo omatshini kunye nokunye. Ngaphaya koko, i-MED inokuphinda isetyenziswe njenge-agent yebhulorho kwi-semi-conductor kunye ne-arhente yokunyanga kwi-epoxy kunye ne-polyurea.
Kwi-4,4'-Methylenebis (2-ethyl-6-methylaniline) / MMEA kwihlabathi jikelele. Imveliso yethu yonyaka yi-400 yeetoni zeemetric.
Ukupakisha: 180kgs / isikhwama; 300kgs/bag, 18kgs/bag
Ukugcina nokuthutha: Gcina kwindawo engenamoya. Njengoko le mveliso ine-hygroscopicity encinci, nceda ugweme ukunxibelelana namanzi kwaye ugweme ukukhanya kwelanga. Vala isikhongozeli ngokuqinileyo emva kokusetyenziswa. Okwangoku, ayinakugcinwa kunye ne-oxidants.
