Te waikawa pungatara kukū i roto i te hanga ahumahi

Whakatutukinga o te ahumahi matū o te ao hou o te tenei ra ki te waihanga matū hou me ngā rauemi, te whakamahi i te whānuitanga o ngā pūhui matū. taea Kotahi tauira te kukū waikawa pungatara, i te mea te tino noa i roto i te ahumahi matū.

waikawa pungatara he te H2SO4 tātai, ko te wai, kahore Pancake tae ōritetanga, i runga te taenga 10,4 ° C te tahuri ki te puranga tioata mārō. Kei te waikawa pungatara kukū 96,4% SO4, a he nui rawa tona mātotoru me te tae 1.87 g / cm, hua i roto i te 1 rita o tarapape ore waikawa pungatara ata whakaaro e pā ana ki 2 kg. Ko reira taa'eraa, ki te wahia te waikawa i roto i te wai, kei te tino nui haere tona pāmahana, mai i te tauhohenga roto he nui nui o hydrates. Kei te whānui tēnei taonga faahiahia whakamahia ki te tutakina ngā matū rite ki te hua o te pāmahana hua wai e kore e anake, engari ētahi atu wai.

Hāngai te waikawa pungatara te whakamahia hoki mō te riringi hau, mai te mea te kaha ki te takanga mai i te rua o wai rerekē. he tika ki te charring o etahi matū waro, rawa warowaihā, i roto i te whakapā ki te waikawa te taua taonga. Ko te meka e roto i warowaihā hauwai me te hāora i roto i te ōwehenga taua rite te H2SO4, hua i roto i te whakapā o enei matū kohikohi waikawa pungatara i te warowaihā wai, tukua waro te rite waro puehu.

I roto i te hanga o pungatara tongi rākau hāngai waikawa, te āhuatanga matū e tukua tona whakamahi rite te kaihoko oxidizing pai, Kei te whakamahia hoki reira ki te teke'i atu waikawa te ahua i te tai. Ka rite ki te hua, ki te taea te whakaputa maniua, pērā i pākawakawa, te haukini pākawa ngāwhā me ētahi atu. Na roto i ngā āhuatanga oxidative, kua whakamahia te reira mo te hāora o konganuku katoa e tu ana i roto i te rarangi i mua i hiriwa conjugation whakakotahi, reira hanga e rua raupapa o tai - Ngā pūkawa (momo reo) me hydrosulfates (momo waikawa) ki tutakina te hākawa.

waikawa pungatara - he wai tino waihā, ano nei he kohu mōrearea. Ko te mōrahi auau whakaaetia o H2SO4 kohu kukū ko 1 mg / m3, ai kaimahi katoa e pā ana ki te waikawa pungatara, workwear tukuna me te taputapu whaiaro paruru. Hāngai waikawa pungatara, te āhuatanga o e he tino kino ki te tangata kahore tiaki, Kei te whakamahia i roto i te wāhi e whai ake nei:

- kōtuitanga organic ahumahi;

- production o rongoä tarukino;

- horoi o ngā hua hinu;

- hiako me ahumahi whakarewa-mahi;

- te hanga o waikano, kirihou, teretere, me te pera i runga i.

hua te waikawa pungatara te i roto i te rua tikanga ahumahi - ki te whakamahi o hoapā totoka (kaiwhakakökï), me te whakamahi i waikura o te hauota (tikanga Sinks). tino maha nga rauemi raw mahi whanariki, engari mo te etahi momo o te waikawa pungatara taea te whakamahi sulfides whakarewa. Industrially hua waikawa takiwa pungatara, te momo e whai ake nei: hangarau, te hinu o vitriol, kupenga (pūhiko), oleum (anhydride) me te pourewa.

I roto i te mutunga, kotahi ano kia fakamamafai reira e te waikawa pungatara, ko te ki te waihā matū paitini 2 piha mōrearea. No te patia i roto i te weranga waikawa inhalation kohu e hanga e o te wahi romahā o runga, haere tahi i te mare tutu, e kia whakawhanake ki Bronchitis, tracheitis , me laryngitis. Ko te aha, no te whakamahi i utua aro nui te waikawa pungatara te ki te nui rawa o te tiaki o kaimahi i te pānga kino o te wai, me te wāhanga'Eta o tenei taonga.
