E rua nga tikanga ahumahi mo te whakaputate houra: te whakamaarama me te hiko. Kua wehea te tikanga causticization ki te houra pungarehu tikanga causticization me te tikanga causticization alkali tūturu rite ki rauemi raw rerekē; Ka taea te wehea te tikanga electrolysis ki te tikanga electrolysis diaphragm me te tikanga membrane whakawhiti katote.
Te tikanga whakamau i te pungarehu houra: Ka huri te pungarehu houra me te kotakota ki te wairewa pungarehu houra, ka huri nga pungarehu ki te miraka kotakota. Ka mahia te tauhohenga whakamaarama i te 99-101 ℃. Ka whakamaramahia te wē causticization, ka whakaeto me te kukū ki te neke atu i te 40%. Te houra wai. Ko te wai kukū ka kukū ake, ka whakakorikori kia whiwhi ai i te hua houra. Ka horoia te paru ki te wai, ka whakamahia te wai horoi hei huri i te alkali.
Ko te tikanga whakamaaramatanga o Trona: ka kurua te trona, ka rewa (he alkali halogen ranei), ka whakamaarama, katahi ka tapirihia te miraka kotakota ki te 95 ki te 100°C. Ka whakamaaramahia, ka whakaeto, ka kuhu ki te kukū NaOH tata ki te 46%, ka whakamataohia te wai marama. , te rerenga tote me te koropupuketanga ki te aro ki te whiwhi i nga hua kua oti i te houra. Ka horoia te paru ki te wai, ka whakamahia te wai horoi ki te whakakore i te trona.
Tikanga hiko Diaphragm: tāpirihia te pungarehu houra, te houra, me te barium chloride kakano hei tango i nga poke penei i te konupūmā, te konupora, me te katote sulfate i muri i te tote tote taketake, katahi ka tapirihia te konutai polyacrylate, te parani kua oti ranei ki te waka whakamaarama hei whakatere i te rerenga, a filtration kirikiri Muri iho, ka taapirihia te waikawa pūhaumāota hei whakakore. Ka whakawerahia te tote ka tukuna ki te hikohiko. Ko te electrolyte ka whakamahana i mua, ka whakaeto, ka wehea ki te tote, ka whakamataohia kia whiwhi ai i te houra kawa wai, ka kukū ake kia whiwhi ai i te hua o te houra kawa totoka. Ka whakamahia te wai horoi paru tote hei whakakore i te tote.
Tikanga membrane whakawhiti katote: I muri i te hurihanga o te tote taketake ki te tote, ka parahia te tote kia rite ki te tikanga tuku iho. I muri i te tātari i te tote tuatahi i roto i te tātari waro tubular microporous sintered, ka parahia ano i roto i te pourewa kapia whakawhiti katote chelating ki te hanga Ka taka te konupūmā me te konupora i roto i te tote i raro i te 0. 002%, ka electrolyzed te tote para tuarua. ki te whakaputa hau maota i roto i te ruma anode. Ko te Na+ i roto i te tote i roto i te ruma anode ka uru ki te ruma cathode na roto i te membrane katote me te OH- i roto i te ruma cathode ka whakaputa te konutai hydroxide. Ka tukuna te H+ ki runga i te cathode hei whakaputa hau hauwai. I roto i te tukanga electrolysis, ka taapirihia he nui tika o te waikawa puota-maama-nui ki te ruma anode ki te whakakore i te OH- kua whakahekehia, a me tapiri te wai parakore e hiahiatia ana ki te ruma cathode. Ko te houra caustic tino parakore i hangaia i roto i te ruma cathode he kukū o te 30% ki te 32% (papatipu), ka taea te whakamahi tika hei hua kawakore wai, ka taea ranei te whakakoi atu ki te whakaputa i te hua houra kawa totoka.
