Waikawa Oxalic

whakaahuatanga poto:

He momo waikawa waro, he hua kaiao o nga rauropi, waikawa rua, ka horahia ki roto i nga tipu, nga kararehe me nga harore, i roto i nga momo rauropi rereke te mahi rereke.Kua kitea he nui atu i te 100 nga momo tipu o te waikawa oxalic, ina koa te parakihi, te amaranth, te pīti, te purslane, te taro, te riwai me te rhubarb.Na te mea ka taea e te waikawa oxalic te whakaheke i te koiora o nga huānga kohuke, ka kiia he antagonist mo te whakauru me te whakamahi i nga huānga kohuke.Ko tana anhydride he waro sesquioxide.

Te taapiri tae

I roto i te ahumahi tā me te tae, ka taea e ia te whakakapi i te waikawa acetic hei hanga tae tuatahi.Ka whakamahia hei kakano me te waikano mo nga waikano poaka.Ka taea te whakakotahi ki etahi matū hei hanga waikano, ka taea hoki te whakamahi hei whakapumau mo nga waikano, na reira ka roa te ora o nga waikano.

Kaihoroi

Ko te whakamahinga o te zeolite hei whakakii i roto i te ahumahi pepa ka taea te whakapai ake i te mahi me te kounga o te pepa, kia piki ake ai te porosity, ka pai ake te whakauru o te wai, he maamaa ake te tapahi, ka pai ake te mahi tuhi, me etahi o te aukati ahi.

Te ahumahi kirihou

Te ahumahi kirihou mo te hanga i te polyvinyl chloride, nga kirihou amino, nga kirihou urea formaldehyde, nga kongakonga peita me etahi atu.

Ahumahi Photovoltaic

Ka whakamahia ano te waikawa Oxalic i roto i te ahumahi photovoltaic.Ka taea te whakamahi i te waikawa Oxalic ki te hanga angiangi hiraka mo nga panui solar, hei awhina i te whakaiti i nga hapa kei runga i te mata o nga angiangi hiraka.

Te horoi kirikiri

Ko te waikawa Oxalic e hono ana ki te waikawa maaota me te waikawa hauwai ka taea te mahi ki te horoi waikawa o te kirikiri kiripaka.

Te whakakōkī whakakōkī

Ka rite ki te whakakōkī mō te kōtuitanga resin phenolic, he ngawari te tauhohenga catalytic, he āhua pūmau te tukanga, a ko te roa te roa.Ka taea e te otinga acetone oxalate te whakakorikori i te tauhohenga whakaora o te kapia epoxy me te whakapoto i te wa whakaora.Ka whakamahia ano hoki hei kaiwhakahaere pH mo te whakahiato o te kapia urea-formaldehyde me te kapia melamine formaldehyde.Ka taea hoki te taapiri ki te waipiro polyvinyl waipiro wairewa-wairewa hei whakapai ake i te tere whakamaroke me te kaha hononga.Ka taea hoki te whakamahi hei kaihoko rongoa o te kapia urea-formaldehyde me te kaihoko katote chelating whakarewa.Ka taea te whakamahi hei kaiwhakatere ki te whakarite i te herenga maaka me te KMnO4 oxidizing agent ki te tere ake te tere o te waiora me te whakapoto i te wa tauhohenga.
