He aha te Dimethyl thio-toluene Diamine DMTDA?

He matū waro nui te Dimethyl thio-toluene diamine (DMTDA), me te nama CAS 106264-79-3. Ka taea e ngā ngota whanariki i roto i te ngota amine DMTDA te whakarei ake i te kaha taunga ki ngā konganuku, ā, i te wa ano ka whakawhiwhia te hua kua rongoatia ki te ātete pai ki te waikura me te ātete ki te waikura matū.

He momo hou te DMTDA o te polyurethane elastomer hei whakaora me te whakawhiti hononga, e rua ngā isomers matua, arā, ko te ranunga o te 2,4 – me te 2,6 – dimethylthiotoluene diamine (ko te ōwehenga he tata ki te 77~80/17~20). Ki te whakatauritea ki te MOCA e whakamahia whānuitia ana, he wai te DMTDA he iti te matotoru i te pāmahana noa, ka taea te whakamahi mō te mahi hanga i te pāmahana iti, ā, he iti te ōrite matū.

Tono

1. Dimethyl thio-toluene diamineHe momo hou o te kaihoko whakaora wai mō te elastomer polyurethane. E whakamahia whānuitia ana te amine Dmtda i roto i te whakarewanga polyurethane, te paninga, te RIM, te SPUA, te potae polyurethane me te piripiri mō te toronga mekameka, te hononga whakawhiti rānei, ā, he kaihoko whakaora anō hoki mō te kapia epoxy.

2. He matū whakaora te Dmtda ethacure 300 mō te kapia epoxy, ā, ka taea te whakamahi hei whakapai ake i te mahi a te kapia epoxy.

3. Hei whakapakeke, ina tāpirihia ki ngā elastomers polyurethane wai-rua TDI me MTDI, me tāpiri i te tere o te 10%. I roto i te umanga hanga me te ahumahi ā-iwi, ka whakamahia te dmtda amine hei tāpiri mō te paninga ātete ahi (paparanga o runga me te pakitara taha), te tiaki waikura o ngā rauemi whakarewa (paninga i te pakitara o roto o te paipa rino), me ētahi atu āhuatanga. Ko te hua polyurethane ka taea te tauhohe ki ētahi atu matū me te kore he maimoatanga he pai ake i te hua o te whakapakeke MOCA (Mocha).

4. Whakamahia mō te tā polyurethane i te rapa waru, te hinu horoi paipa waru, me ētahi atu, hei whakapai ake i te ātete hinu o te polyurethane, ā, he iti hoki te tere whakawhanui rōrahi.

5. Hei tāpiritanga, ko te amine dmtdae whakamahia whānuitia ana i roto i ngā ahumahi kakahu, pepa me te tā. E taea te kī he whānui te mākete o te dimethyl thio-toluene diamine, mai i te ahumahi rererangi me te ātea ki te ahumahi ā-iwi whānui.

Ā mātou painga

1. He nui ake te ihirangi o tā mātou DMTDA i ngā paerewa ahumahi, ā, neke atu i te 96% te roa o ia puranga.

2. He nui ake te uara amine i ngā paearu ahumahi, ā, ka eke pumau ia puranga ki te 530mgKOH/g, ka puta he mahi whakaora tino pai.

3. He nui te kaha whakaputa me ngā taonga hou, ka oati mātou kia tere te whakatutuki i ngā ota, ā, ka taea te tuku i roto i ngā rā mahi e 5.

4. Haunga ā mātou takai pahu 200kg paerewa, ka tukuna atu e mātou ngā kōwhiringa takai ritenga me ngā ratonga tā waitohu kua whakaritea kia rite ki ō hiahia.
