99% MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Ko te Methylenebis (2-chloroaniline), e kiia ana ko te MOCA, he matū e whakamahia ana hei hononga whakawhiti/whakaroa mekameka mō ngā hua polyurethane, inā koa mō ngā elastomers polyurethane whakarewa (CPU). He ngāwari, he ngāwari hoki ngā elastomers polyurethane pērā i te rapa engari he āhuatanga nui, ka whakakotahi i te ngāwari teitei o te rapa me te pakari o te kirihou. Ko ngā āhuatanga o te MOCA he pumau tae i te pāmahana teitei. He pai ngā elastomers turanga-MOCA mō te ātete ki te pakū/pānga/matū/hinu/ozone me te makariri, he ngāwari ahakoa te pakeke teitei, iti rānei (whakatauranga Shore A ki Shore D), he kaha teitei o te kume/haehae/kōpeketanga, me te mimiti i te wiri. Nā te roa o te ora o te kohua, he tino ngāwari ki te whakamahi, ka taea e koe te whakamahi ā-ringa hei utu mō ngā mīhini. Nā aua āhuatanga ā-tinana me ngā painga, ko te MOCA te hononga whakawhiti/whakaroa mekameka tino noa mō ngā elastomers urethane (pūnaha TDI). I taua wā, he kaihoko whakaora whānui hoki mō ngā hua Epoxy.
Ki te whakataurite ki te DETDA me te DMTDA, tera etahi painga kitea o te MOCA e whai ake nei.
1. He mārama ake te tae o te hua kua oti.
2. He momo totoka te MOCA, nō reira, he māmā ake te penapena me te iti ake o te parahanga.
3. Ngāwari ki te pupuri. He roa te ora o te kohua.
4. He teitei ake te Modulus.
5. Utu iti iho.
Ko te MOCA he whakaroa mekameka diamine kakara, he mea whakaora rānei e whakamahia whānuitia ana i roto i te whakarewanga o ngā elastomers polyurethane, ngā rauemi papa elastomeric, ngā paninga ātete wai PU, ngā piripiri PU, ngā pahuka PU, me ētahi atu.
Ko ngā elastomers PU kua whakaroahia e te mekameka MOCA e whakamahia whānuitia ana i roto i ngā mara tae atu ki te mīhini, te hanga whare, ngā waka, te kawe waka, te ahumahi keri, te whakakī i ngā wāhanga hiko me te whare hākinakina, me ētahi atu.
Ka taea hoki te whakamahi i te MOCA hei whakaora i te kapia epoxy.
He tino parakore te MOCA, he wai mārama te MOCA rewa, kāore he tae, he kowhai te tae, ā, e taunakihia ana kia whakamahia i roto i ngā mahi pēnei i te wira papa reti, te roera whakakoi raihi polyurethane, te waru, te rama.
ngā paninga PU tae, me ētahi atu e hiahia ana ki te āhua pai, me te āhua mārama, tata kore tae.
He mea rongonui te MOCA hei whakaroa mekameka kakara diamine, hei whakamaroke rānei mō te whakarewa i ngā elastomers polyurethane (PU). He tino pai ngā āhuatanga o ngā elastomers turanga-MOCA, ā, e whakamahia whānuitia ana i roto i ngā momo mara tae atu ki te hanga whare, te hanga whare, ngā waka, te keri maina, te haurua-kawe, te epoxy, te whare hākinakina me ētahi atu.
1. Kaihoko hononga mō te umanga hiko.
2. Rauemi/paninga ā-wai mō te hanga me te ahumahi hoahoa whare.
3. He mekameka whakaroa mō ngā elastomers PU, arā, he hononga rapa kauae, he pūngāwerewere PU.
4. Kaiwhakaora mō te kapia epoxy.
5. Ngā wāhanga mō te whakamahinga ahumahi, arā, ngā whitiki kawe, ngā wira, ngā roera ārahi, ngā hononga.
6. Ngā papa mimiti ru mō te umanga motuka.
7. Ngā roera tā, ngā mata pahu, ngā mata squeegee, ngā mata horoi, ngā mata waru mō te umanga tā.
8. Rauemi hiri.
9. Rauemi whakamahana epoxy.
10. Rau urethane ārai mate huakita.
11. Mata wehewehe kohuke.
12. Ngā arai paipa.
Te tākai: 25 kg, 50kg rānei/pūwero muka, putea rānei
He iti noa te mimiti i te makuku; kaua e pā ki te wai. Puritia kia matara atu i te rā.
