Aramid Fiber

Ko te muka Aramid e kiia ana ko te polybenzoylenediamine, me te muka waro, ultra-high molecular weight polyethylene fiber me te toru o te ao nui o te muka mahi teitei, he iti te kiato, te kaha teitei, te modulus teitei, te teitei o te pāmahana, te aukati i te waikura, te whakamatao, e whakamahia nuitia ana i roto i te hōia, aerospace, taputapu hiko, waka, hanga, hauora me etahi atu mara.Ko te muka Aramid he muka polyamide kakara, he mea hanga mai i te polymer linear synthetic (he iti rawa te 85% o te here amide e hono tika ana ki nga mowhiti kakara e rua) i tito mai i te here amide hono whakakai kakara (Ar-CONH-Ar).Ko te mekameka matua ko te mowhiti kakara me te here amide, a he pakari te hanganga mowhiti kakara.Ka horahia te mekameka polymer hei hanga i te ahua o te rakau.

I te wa ano, ko te hanganga raina o te mekameka ngota ka nui te tere o te whakamahi i te mokowā muka aramid, na reira ka taea e te roopu roopu te whakauru atu i te polymer, na reira ka kaha ake te kaha.He rereke mai i nga mekameka rapoi polymer ngawari noa, ko te hanganga mekameka matua o te muka para-aramid te nuinga o te hanganga rapoi rakau-rite i hangaia e te mowhiti benzene.Na te mea he nui te whakakai benzene conjugated, he uaua ki te huri i roto i te wahanga mekameka ngota, na reira ka whakaatu mai he hanganga maaro.
