Te pūngāwhā hāora rua

Pūngāwhā waikura (IV) he ingoa, ano mana whakamahia i roto i te pūtaiao matū - whanariki hāorarua, i roto i te tua, kua karangatia e hoki tenei taonga whanariki te pūngāwhā hāora rua hāorarua ranei. Pūngāwhā waikura (IV) i raro i ngā āhuatanga noa - tenei hau te kore tae, me te kakara kino, motuhake rawa, i te mea haamana'oraa o te kakara o te kēmu i te wa o te pātīmata.

liquefied te hau e te whakanui ake i te pēhanga, e kore ai te pāmahana rerekē i te ruma noa. Ko te rawa he wairewa i roto i te wai ki te hoatu te waikawa sulfurous iu. Ko te tohu o te memehatanga wai o pūngāwhā hāora rua ko i te pāmahana o te 20 F 11,5 karamu o kaihoko ia 100 karamu o te wai. Te mea faahiahia, ina ara ake te pāmahana, te taumata o te memehatanga o te pūhui heke. Haunga te wai, he wairewa i roto i te waihā me te pūngāwhā hāora rua te waikawa pungatara. I roto i te natura, te pūngāwhā hāora rua, tona tātai he SO2, ko tetahi o nga mea timatanga whakatu hau puia.

kia hoki te hanga ahumahi o te pūngāwhā hāora rua e hāngai ana i runga i te tahunga tika o te whanariki kia rite e pupuhi nga sulfides hau, rawa pērā i pyrite.

whiwhi pūngāwhā hāora rua te me tikanga taiwhanga. kawea hoki te tenei tauhohenga i runga i te pānga o ngā whākawa waikawa kaha. Ka rite ki te taonga taketake whakamahia i roto i ngā taiwhanga pūtaiao, me te hydrosulfites. homai he tauhohenga taua e te whārite: Na2SO3 + H2SO4 → Na2SO4 + H2SO3. Ko te hua o te tauhohenga rite kitea i te whārite, te waikawa sulfurous, e no te mea o tona tapepe decomposes tonu ki te pūngāwhā hāora rua, me te wai.

Kei te whakamahia rauemi Iti mo te tikanga i roto i nei pānga i runga i te konganuku iti kaha ki te waikawa pungatara memeha, me puta ai te tauhohenga i te para i te otinga mahi.

āhuatanga matū Major o enei te hauhā whanariki.

whenumi pūngāwhā hāora rua e i roto i te whānuitanga hihi katinga o te hihinga. whakarōpūtia ngā reira rite te waikura waikawa. Ka rite ki kua tuhia, he wairewa i roto i te wai i roto i te tauhohenga matū reversible te hāorarua whanariki.

I te whakataki o te hau ki roto ki te tauhohe ki te alkali hua whākawa i whānui, ki te ki te tohu i te tauhohenga o tenei hau, kia whakaae ai ko reira tino nui. I roto i tauhohe tino nuitia whakakitea whakaiti āhuatanga o te taonga, me te taumata o te whanariki piti hāora i roto i te tauhohe, riro teitei.

āhuatanga hāora o pānui pūngāwhā hāora rua i roto i tauhohe tahi e te hāora kaha. Hei tauira, i roto i te rängai ahumahi mo te hanga o te whanariki tikanga e whakamahia ana parori ki ona waikura fakafoki mai waro (II).

Pūngāwhā waikura (IV) i roto i te ahumahi matū nuinga whakamahia ki te whakaputa i te waikawa pungatara. I roto i te whānui, he tino whanui, me te rangirua tona tono. Ko te take i he paitini whanariki hāorarua. Na roto i te inhalation taea te tiki pau tohu e nui korokoro, ihu mātihetihe, mare. Inhalation kino whanariki hāorarua hopoi te neke atu i ko reira runga ake te kukū o te taonga. I nohanga teitei taea puta nunu'a mamafa, ki runga ki te whakahēmanawatanga, disorders kupu me te edema pūkahukahu.

whakamahia pūngāwhā waikura (IV) i roto i te ahumahi kai, i roto i ngā he reira hakari i roto i inu slaboalkogolnyh rite te rokiroki. I roto i te ahumahi pueru e whakamahia reira rite te huānga wāhanga o te tikanga mō te bleaching he momo o ngā rauemi e kore e taea te tarautete pūhui māota.

I roto i te taiwhanga ahumahi, me te mātauranga whanariki waikura (IV) mahi rite te whakarewa mahuinga ia, engari i roto i tenei take me mahara ai e i roto i te hau e taea i roto i poke o te wai, me te SO3, e mogtst pā te viivii ore, me te akoranga tika o te tauhohenga i te aroaro o te silica. Na reira, i roto i enei take purea te hau e na roto i te haere i roto i te tātari kei roto takiwa H2SO4, tonu i roto i te oko kati.

Nā ki whānui mahi hāorarua whakamahi whanariki rite tetahi o nga matū nui whakapoke i te kōhauhau. tukunga Ngā mōrearea hua i ngingiha o to tatou pūngao mua - waro, kapuni, me te hinu. Ka rite ki te tikanga, te nuinga o ngā pānga kōaro kei roto i ngā rerenga, no te mea o te anake - he hakari i roto i te puka aerosol te hua mutunga.

I tēnei wā, whakanuia te kukū rawa o tenei hau e i roto i te tuakoi raki, ngā i runga i te United States, Ukraine, Western Europe me i roto i nga rohe ki te hauauru o Russia.
