Ka taea te whakamahi i te waikawa Fumaric hei kaiwhakahaere waikawa

Ko te waikawa Fumaric, e mohiotia ana ko te waikawa fumaric, te waikawa puru, te waikawa lichenic ranei, ara te waikawa fumaric (ingoa IUPAC (E) -butenedioic acid), he karaihe kore tae, he mura ahi i tito mai i nga waikawa Carboxylic i ahu mai i te butene. Ko te wera o te waikawa fumaric ka whakaputa i nga kohu anhydride maleic. He rite te reka o nga hua ka kitea i Corydalis, Boletus, Lichens, me Icelandic Nori.

Whakaahuatanga

Ka whakamahia te waikawa fumaric ki te hanga kapia polyester haunga. Ko tenei momo kapia e tohuhia ana e te pai o te matū me te wera wera; ko te copolymer o te waikawa fumaric me te vinyl acetate he pai te whakapiri. Ko te copolymer me te styrene te rauemi mata mo te hanga FRP. Ko te plasticizer i hangaia e te waikawa fumaric he kore-paitini, ka taea te whakamahi mo te vinyl acetate latex e pa ana ki te kai. Ko tenei hua he takawaenga matū pai penei i te rongoa me te kaihoko whakapouri whatu. Ka whakamahia i roto i te hanga o te waikawa dimercaptosuccinic antidote i roto i te umanga rongoa. Ka whakakorehia te waikawa fumaric ki te konutai warowaihā kia whiwhi ai te konutai fumarate ([17013-01-3]), ka whakakapihia ki te ferrous sulfate ki te tango i te rino fumarate, e whakamahia ana ki te rongoa i te anemia iti o te toto whero me nga raau taero-rino. Ka whakamahia tenei hua hei kai taapiri-kawa, ka whakamahia i roto i nga inu whakamaarama, te parani hua, te tiēre, te aihikirimi, me era atu mea, ko te nuinga o enei ka whakamahia me te waikawa citric kaihoko kawa. Ko te tote monosodium i hangaia e te tauhohenga o te waikawa fumaric me te konutai konutai, Ka whakamahia ano hoki hei whakakawa kawa me te takawaenga mo te kapia waihanga me te mordant.

Taupānga

I roto i te kai e whakamahia ana i roto i nga hua kai, te tukatuka hua ika me etahi atu. Ka taea te whakamahi i te waikawa Fumaric hei kaiwhakahaere waikawa, hei kaiwhakawa, hei antioxidant, hei kaiwhakatairanga tote me nga mea kakara. Ko tenei hua he kaha kaha ki te pupuri i te wairewa wai mo te pH3.0, a he mahi nui ki te aukati i te antibacterial me te koriri, i te wa ano, he reka astringent, ko tetahi o nga waikawa totoka tino waikawa, he iti te tere o te whakauru, me te awhina ki te whakawhānui ake i te oranga o nga hua paura. Ina huri te waikawa fumaric ki te konutai fumarate, ka pai ake te wairewa me te reka o te wai.
