Pūngāwhā waikawa me tona whakamahinga

waikawa pungatara Ko tetahi o te pūhui matū tino pai-mohiotia, me te noa. Ko matua te take ona āhuatanga pai-tautuhi. Ko tōna tātai - H2SO4. Tenei diacid he te teitei āhua piti hāora o te whanariki +6.

I raro i ngā āhuatanga noa waikawa pungatara ko te wai, kahore kakara, me te tae, he āhuatanga hinuhinu. Kei te whānui horahia e te reira i roto i te toi me te ngā ahumahi.

I te kau, tenei taonga ko tetahi o te matū tino nui, me te tino noa, me hua matū. I roto i te natura, putunga whanariki taketake puta noa kahore pera maha rite te tikanga, kua kitea te reira anake i roto i te pūhui ki ētahi atu matū. Kei te whakawhanake te reira i hanga o ngā pūhui whanariki, tae atu i te momo o ururua ahumahi. I roto i ētahi wā, hau konganuku ferrous taea te urutau ki te whakaputa i whanariki, me te ngā pūhui reira.

āhuatanga

waikawa pungatara pēhia ngā tetahi pūhui organic. E te reira i te wai i a ratou rawa hohoro, kia timata te papanga me pūhui rerekē ki te Pūāhua. 100% waikawa ko tetahi o te kaha, e kore e te pūhui paowa me e kore e whakangaro i te konganuku ferrous.

waikawa waimeha pungatara tauhohe ki tetahi konganuku atu atu i ārahi. I roto i te puka takiwa haamata te reira ki te oxidize maha āhuatanga.

Ko te whakamahi o te waikawa pungatara

Te nuinga whakamahia te waikawa pungatara te i roto i te ahumahi matū, te wahi e hāngai ai hua hauota me maniua Phosphate, tae atu pākawakawa, e te whakaaro tēnei wā tetahi o nga maniua tino noa. Ia tau hua ake ki te maha miriona toni o te taonga.

I roto i te metallrugii whakamahia H2SO4 te ki tirohia te kounga o te hua. A, no te kia puta maitai hurihia moroiti-kapiti i roto i te tikanga ki te kitea a ratou, whakanohoia te tūemi e i roto i te pati mata, a te maungärongo 25% otinga o te waikawa. I muri i taua, e taea te kite ara nga kapiti iti rawa ki te kanohi tahanga.

I mua i te tono i te whakarewa whakakikoruatia he tika taua mea ki te faaineine i mua - horoia, ka degreased. Mai tauhohe te waikawa pungatara ki ngā konganuku, memeha reira te kahupapa, a ki reira tango tetahi tohu contamination. I tua atu, riro taratara te mata whakarewa, i te mea pai hāngai hoki te tono o nika, chromium parahi whakakikorua ranei.

whakamahia te waikawa pungatara te i roto i te tukatuka o etahi tokahuke, he reira ano hoki te nui nui e hiahiatia ana i roto i te ahumahi hinu te wahi te whakamahia ai te nuinga mo te purenga o ngā hua. Kei te maha whakamahia te reira i roto i te ahumahi matū, e te tipu tonu. Ka rite ki te hua, kitea atu kaha, me tono. Ka taea te whakamahi i tēnei rauemi mo te hanga o te mata-waikawa puna o nāianei - ngā pākahiko.

Te faaineineraa o te waikawa pūngāwhā

Ko te matua rauemi raw mō te whakaputa whanariki me te waikawa mahi ngā pūhui e hāngai ana ki runga ki taua mea. Ano, rite kua whakahuatia, kua whakawhanake i te reira te whakamahi o ururua ahumahi ki te whakaputa i whanariki. I roto i te rīhi oxidative o tokahuke sulfide i roto i hau whakapau SO2. Kei te taunga reira ki te whakaputa i te waikawa pungatara. Ahakoa tonu Russia ki noho te tūranga ārahi i roto i te tukatuka e hāngai ana production-o pyrite, tahuna nei i roto i oumu. A, no te hau wera i runga i te pyrites e hanga e he rua o SO2 tiketike. Hei tango poke, me te tahi atu kohu mōrearea hiko whakamahia. Na te hanga o whakamahia whānuitia tikanga rerekē mō te whakaputa waikawa, a he tokomaha o ratou e pā ana ki te ururua whakahaere, ahakoa te rahi tiketike o ahumahi tuku iho.
