Ojiji
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) bụ ihe mejupụtara organic, ụzọ isi eji ya eme ihe bụ ndị a:
- Njikọta nke Ihe Polyurethane: MOCA bụ ihe dị mkpa maka ịgbatị yinye maka polyurethane elastomers. N'imepụta polyurethane, isocyanate prepolymers kwesịrị imeghachi omume na ihe ndọtị yinye iji mepụta polymers polyurethane dị arọ nke molekul. MOCA nwere mmeghachi omume dị elu na isocyanates, nke nwere ike ịgbatị yinye polyurethane molekul nke ọma ma melite ike, ike, iguzogide iyi, iguzogide ndọda na ihe ndị ọzọ nke ihe ahụ. A na-ejikarị ya eme ihe na imepụta ngwaahịa polyurethane elastomer dị elu, dị ka efere sieve, rọba rollers, seals, wdg. eji eme ihe na ụlọ ọrụ dịka igwu ala, metallurgy, na petroleum. Ngwaahịa ndị a kwesịrị inwe ezigbo iguzogide iyi na ihe onwunwe igwe.
- Ihe Na-agwọ Ọrịa Maka Epoxy Resins: Enwere ike iji MOCA mee ihe dị ka ihe na-agwọ ọrịa maka resin epoxy. Ọ na-eme mmeghachi omume njikọ cross-couple na resin epoxy iji mepụta nhazi netwọk atọ, si otú a na-agwọ resin epoxy. Resin epoxy a gwọrọ nwere ezigbo ihe eji arụ ọrụ, iguzogide nchara kemịkalụ, na iguzogide okpomọkụ. A na-ejikarị ya eme ihe n'imepụta ụfọdụ ngwakọta epoxy nwere ihe achọrọ arụmọrụ dị elu, dị ka n'ọhịa nke ihe eji eme ite eletrọnịkị na mkpuchi ala. Ihe eji eme ite eletrọnịkị kwesịrị ichebe ihe eletrọnịkị dị n'ime site na gburugburu mpụga. Resin epoxy a gwọrọ site na isonye na MOCA nwere ike inye ezigbo mkpuchi na nchekwa igwe. Ihe mkpuchi ala epoxy kwesịrị inwe ihe ndị dị ka iguzogide iyi na iguzogide nchara iji mezuo ihe achọrọ maka ojiji nke ebe dị ka ebe ọrụ ụlọ ọrụ na ebe a na-adọba ụgbọala.
