4,4′-Methylenebis(2-ethyl-6-methylaniline) / MMEA CAS Nu. 19900-72-2
4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, CAS numera 19900-72-2, o loʻo faʻaaogaina e avea o se faʻalauteleina o filifili mo polyurethane elastomers ma o se vailaʻau faʻamalolo mo le epoxy resin e faʻaleleia ai mea faʻainisinia ma malosi. o oloa. MED e mafai foi ona faʻaaogaina e fai ma taʻiala taʻutaʻua mo polyimides ma o se faʻasalalauga mo le faʻaogaina o meaola.
E fetaui lelei mo le lafoina o le polyurethane (CPU), polyurethane thermoplastic (TPU), elastomers RIM ma le faʻafefe polyurea i le fanua polyurethane. MED e talafeagai foi mo le gaosiga, prepreg ma vailaau anticorrosive coatings i le epoxy resin fanua. O loʻo faʻaaogaina le MED i le tuʻufaʻatasia o prepolymers, e aofia ai polyether ma polyester.
MED o se fofo lelei mo oloa maeʻa e manaʻomia le lanu malamalama ma le matua. E mafai ona fa'aogaina le MED ma isi vaila'au fa'amalolo fa'a-amine (compound) e fa'afetaui ai mea totino lelei.
MED ma MOCA o vailaʻau faʻamaʻi amine-ituaiga. Ae ui i lea, o le MED e faʻaleleia le siʻosiʻomaga ma faʻaitiitia le filogia pe a faʻatusatusa i le MOCA. E mafai foi e le MED ona sui le MBOEA ma le HQEE i luga o oloa PU, e tusa lava po o le PPU (tu'i le polyurethane) poʻo le TPU (thermoplastic polyurethane). E tutusa ma le MOCA, MED-type elastomers faʻaalia ma sili atu le vevela-teteʻe manaʻomia ile galue ile 120℃
O le MED/MMEA ose mea manogi e fa'alautele ai filifili ma fa'amalolo. Ona o tulafono faʻatonutonu i le faʻaaogaina o le MOCA, o le MED e faʻafeiloaʻi, e le faʻaleagaina o se isi filifiliga lelei e faʻaoga i luga o le tele o talosaga. MED-base polyurethanes o le agavaʻa ma le saʻolotoga o mamanu, faʻatasi ai ma meatotino malosi maualuga aʻo faʻatumauina lona elasticity. O oloa MED-ituaiga maeʻa e umi ma faʻasaʻo lea e mafai ai ona fetaui lelei mo faʻaoga manaʻomia, e pei o paʻu paʻu, casters, rollers, forklift paʻu, masini masini ma isi. E le gata i lea, e mafai foi ona faʻaaogaina le MED e avea o se alalaupapa alalaupapa i luga ole semi-conductor ma avea ma se faʻamalolo i luga ole epoxy ma polyurea.
Mo 4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA i le lalolagi atoa. O la matou gaosiga faaletausaga e 400 metric tone.
afifiina: 180kgs / taga; 300kgs / taga, 18kgs / taga
Teuina ma felauaiga: Teu i se nofoaga e savili lelei. Ona o lenei oloa e laititi le hygroscopicity, faamolemole aloese mai le faʻafesoʻotaʻi i vai ma aloese mai le susulu o le la. Faamaufa'ailoga lelei le koneteina pe'a uma ona fa'aoga. I le taimi nei, e le mafai ona teuina i oxidants.
