He aha te Dimethyl thio-toluene Diamine DMTDA?

Ko te DMTDA he momo hou mo te rongoa polyurethane elastomer me te kaihoko whakawhiti, kei roto i te nuinga o nga waahanga e rua, ko te ranunga o te 2,4 - me te 2,6 - dimethylthiotoluene diamine (ko te ōwehenga kei te 77 ~ 80/17 ~ 20). Ka whakatauritea ki te MOCA e whakamahia nuitia ana, ko te DMTDA he wai he iti te pokey i te pāmahana noa, ka taea te whakamahi mo te mahi hanga i te iti o te pāmahana, me te iti o te matū rite.

Taupānga

1. He momo hou mo te rongoa wai mo te polyurethane elastomer. Ka whakamahia nuitia i roto i te whakarewanga polyurethane, te paninga, te RIM, te SPUA, te potae polyurethane me te whakapiri mo te toronga mekameka, te hono-whakawhiti ranei, a he kaihoko rongoa mo te kapia epoxy.

2. Hei whakamaroke, ka whakauruhia ki te TDI me te MTDI e rua-wai nga elastomers polyurethane, me taapiri i te tere o te 10%. I roto i te hanga me te ahumahi a-iwi, he maha nga wa e whakamahia ana hei taapiri mo te paninga ahi (te paparanga runga me te taha taha), te whakamarumaru o te waikura o nga mea whakarewa (te paninga ki te pakitara o roto o te putorino rino), me etahi atu waahanga. Ko te hua polyurethane ka taea te urupare ki etahi atu matū me te kore he maimoatanga he pai ake i te hua o te MOCA (Mocha) whakapakeke.
3. Whakamahia mo te polyurethane tā rapa scraper, te hinu paipa horoi waruwaru, me ētahi atu, ki te whakapai ake i te hinu ātete o te polyurethane, a he iti hoki te tere roha rōrahi.
4. I tua atu, e whakamahia nuitia ana i roto i te papanga, te pepa me te ahumahi tuhi. Ka taea te kii he whanui te maakete mai i te umanga rererangi me te umanga aerospace ki te umanga a-iwi whanui.
