Ibisobanuro by'igicuruzwa

4,4'-Methylenebis (2-ethyl-6-methylaniline) / MMEA, CAS nomero 19900-72-2, ikoreshwa nk'inyongera y'uruhererekane rwa polyurethane elastomers ndetse n'inyongera ya epoxy resin kugira ngo inoze imiterere n'ingufu by'ibicuruzwa. MED ishobora kandi gukoreshwa nk'ikintu cy'ingenzi cya polyimides ndetse n'inyunganizi mu gukora organic synthesis.

Ikwiriye cyane mu gucukura polyurethane (CPU), polyurethane ya thermoplastic (TPU), elastomer ya RIM na polyurea yo kujugunya mu murima wa polyurethane. MED ikoreshwa kandi mu gutunganya, gutegura no gusiga irangi rya shimi rirwanya ububobere mu murima wa epoxy resin. MED ikoreshwa mu gukora prepolymers, harimo polyether na polyester.

MED ni igisubizo cyiza ku bicuruzwa byarangiye bisaba ibara ryoroheje kandi birwanya gusaza. MED ishobora gukoreshwa hamwe n'ibindi bintu bivura indwara zo mu bwoko bwa amine (ikivange) kugira ngo bihuze imiterere myiza y'umubiri.

MED na MOCA byombi ni imiti ivura ubushyuhe mu bwoko bwa amine. Ariko, MED ntingiza ibidukikije kandi ntihumanya cyane ugereranyije na MOCA. MED ishobora kandi gusimbura MBOEA na HQEE ku bicuruzwa bya PU, haba kuri CPU (casting polyurethane) cyangwa TPU (thermoplastic polyurethane). Kimwe na MOCA, elastomer zo mu bwoko bwa MED zifite ubushobozi bwo kwirinda ubushyuhe bwinshi kandi zisaba ubushyuhe burenze 120℃.

Porogaramu

MED/MMEA ni umuyoboro w’amavuta uhumura neza kandi uvura. Bitewe n’amabwiriza akaze agenga ikoreshwa rya MOCA, MED irinda ibidukikije kandi idahumanya ni ubundi buryo bwiza bwo gukoresha ku bintu bitandukanye. Polyurethane za MED zifite ubushobozi bwo gukora ibintu bitandukanye kandi zifite ubwisanzure mu gushushanya, zifite ubushobozi bukomeye kandi zigumana ubuziranenge bwazo. Ibikoresho bya MED biraramba kandi birakomeye, bigatuma biba byiza mu bikorwa bigoye, nka bumper pads, casters, roller, forklift pine, ibice by’imashini n'ibindi. Byongeye kandi, MED ishobora no gukoreshwa nk'umuyoboro w'amazi kuri semi-conductor no nk'umuyoboro w'amazi kuri epoxy na polyurea.

Gupakira no Kubika
