MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), inonziwo MOCA, chinhu chinoshandiswa sechinhu chinosanganisa / cheni extender kune zvigadzirwa zve polyurethane, kunyanya zve cast polyurethane elastomers (CPU). Polyurethane elastomers inochinjika uye ine elasticity hunhu senge rabha asi ine yakakosha zvimiro, inosanganisa yakakwirira elasticity yerabha uye kuoma kwepurasitiki. MOCA inoratidzira ine kugadzikana kwemavara mukupisa kwakanyanya. MOCA-base elastomers yakanakira abrasion / kukanganisa / makemikari / mafuta / ozone uye kutonhora kuramba, elasticity zvisinei nekuoma kana kuderera (Shore A kusvika kuShore D rating), yakakwira tensile / kubvarura / kudzvanya simba, uye kunyura kwekudedera. Nehupenyu hurefu hwepoto, zviri nyore kubata nazvo, unogona kubata nemaoko pachinzvimbo chemichina. Zvichibuda kubva kune izvo zvemuviri zvivakwa uye zvakanakira, MOCA ndiyo yakajairika crosslinking / cheni extender yeurethane elastomers (TDI system). Zvichakadaro, iri zvakare mumiririri wepasi rose wekurapa weEpoxy zvigadzirwa.
Kuenzanisa neDETDA & DMTDA, pane zvimwe zviri pachena zvakanakira MOCA sezvinotevera.
1. Chigadzirwa chakapedzwa chakareruka muvara.
2. MOCA yakasimba mhando, saka, zviri nyore kuchengeta uye kushoma kusvibiswa.
3. Zviri nyore kubata. Hupenyu hurefu hwepoto.
4. Modulus yakakwirira.
5. Mutengo wakaderera.
MOCA inozivikanwa inonhuhwirira diamine cheni extender kana kurapa mumiririri wekukanda polyurethane (PU) elastomers. MOCA-base elastomers ane zvivakwa zvakanakisa, anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana kusanganisira kuvaka, kuvaka, mota, migodhi, semi-conductor, epoxy, sport nzvimbo uye zvichingodaro.
1. Bridging agent yeelectronic industry.
2. Mvura isina mvura / kukoira kwekuvaka & indasitiri yezvivakwa.
3. Chain extender yePU elastomers, kureva shaya rubber coupling, PU spider.
4. Kurapa mumiririri we epoxy resin.
5. Zvikamu zvekushandiswa kwemaindasitiri, kureva mabhandi ekutakurisa, makanda, kutungamira rollers, couplings.
6. Shock absorption pads yeindasitiri yemotokari.
7. Kudhinda rollers, zvigubhu, squeegee blades, kuchenesa mashizha, scraper blades yekudhinda indasitiri.
8. Kuisa chisimbiso.
9. Epoxy insulation zvinhu.
10. Antibacterial urethane sheet.
11. Mineral separation screen.
12. Pipe linings.
