Konurehu pākatirua pūmura

He maha ngā ingoa, e, ki te nui, iti ranei o te auau, e whakamahia i runga i te mara o te whakamahi o te taonga iho rānei taonga konurehu pākatirua pūmura. I ngā wā, ko te ariā matū o te tino whakamahia nuitia ingoa konurehu pākatirua pūmura pāhare pāporo ranei Chrompick. A, no te haere mai te reira ki te whakamahi ahumahi, te mea kiia tenei pūhui Chrompick. He mea tino nui ki te mahino rite te mea ahua o te hononga i roto i te pātai, no te mea i roto i te whakamahi ia rā te karanga a hoki Chrompick konutai pākatirua pūmura tātai Na2Cr2O7 * 2H2O. tātai Chemical bichromate pāhare pāporo - K2Cr2O7.

Ko te āhuatanga ōkiko o te pāhare pāporo bichromate e whai ake nei. Waho, tenei taonga ko te tioata karaka-tae, karaihe wini whakakahokaho o e he tāupe i raro i te mana o te pāmahana. A, no te ona uara ki te 257 ° C wini triclinic kua te ahua o tioata kotahi, a ka ara ake te pāmahana i runga 257 ° C, taui te reira ki te puka monoclinic.

Konurehu pākatirua pūmura taonga he pāmahana rewa o 396 ° C, me ona hua i runga i 500 ° C decomposes taonga i runga i K2CrO4, Cr2O3 me te hāora. Pāhare pāporo bichromate mahara motuhake ko 2.69 g / cm3. Ko tino wairewa i roto i wairewa waiwai konurehu pākatirua pūmura:

- i te pāmahana o te 0 ° C, 100 karamu o te wai kei te tino memeha 4.6 karamu o pāhare pāporo bichromate;

- i te pāmahana o te 25 ° C, e taea te tino memeha te taua nui o te wai kua 15.1 karamu, me te pāmahana e whakaarahia ki 50 ° C - ko te 37.7 karamu.

I roto i te waiwaihā, hei tauira, te waihā, pākatirua pūmura paku wairewa pāhare pāporo.

Pāhare pāporo bichromate hanga he eutectic - otinga wai hiato e crystallizes i raro i te pāmahana iti mo tenei rōpū o matū tātai hanganga tito o nei - H2O - K2Cr2O7 ki te ihirangi konurehu bichromate 4.30%, he mea pauna. Ko te pāmahana rewa o tenei pūhui anake 0,63 ° C, me te kohua i te reira i 104,8 ° C (pāhare pāporo bichromate i roto i te otinga - 52% i te taimaha).

C e pā ana pērā matū rite konurehu pākatirua pūmura, tauhohe tango te wahi i roto i te pāpāho waikawa, ki te kei reira te wairewa. Ko taonga ano hoki te kaihoko kaha oxidizing, hei tauira, i te tauhohenga o te pāhare pāporo bichromate me te whanariki whiwhi K2SO4 tote me te chromium ōkai.

Na roto i te tauhohe i ki waikawa pāhare pāporo puka bichromate polihromaty pungatara me te nitric. A, no te whakawera ranunga kei roto tenei pūhui me te hauwai waikuratei e whiwhi ngāwari taikaha tioata hauwai e, i roto i te tahuri, ko te wāhanga nui o explosives.

Industrially kawea faaineineraa bichromate konurehu te roto i te utu tauhohe ki Na2Cr2O7 KCl, i te mea wera ki nui pāmahana te otinga - e pā ana ki 1000 - 1300 ° C.

Kei te whakamahia konurehu pākatirua pūmura, kua whakaahuatia te āhuatanga matū o nei ki runga ake i te hanga o ngā waikano ngā i roto i te pueru, me te hiako ngā ahumahi, kei te whakamahia te reira i roto i te tanning hiako. tono Tūaritia i roto i te rakau tukatuka me te ahumahi o kēmu, te hanga o pyrotechnic ranunga pikitia. Ki te rewa pāhare pāporo konurehu bichromate i te waikawa pungatara, homai ana e ia he otinga rawa whai hua mō ngā mea karaihe horoinga i roto i te taiwhanga. Ka rite ki te wāhanga o te bichromate konurehu pāporo whakamahia electrolytes i roto i te maroke me te i roto i te tukanga metallurgy konganuku waikura inhibitor me ratou alloys.

Chrompick pāhare pāporo - he pūhui tino paitini. Pata o te otinga ona, hinga i runga i te wāhi kitea o te tinana, whakangaro te kiri. Ahakoa nohanga iti o tenei taonga ka taea e meinga kino nui ki te wahi romahā me te tūkino i te kiko wheua ngohe nape. take mohiotia o kino whatukuhu, ate me te wahi gastrointestinal. Na reira, ko te hanga o mahi ki konurehu pākatirua pūmura kia tino whakatinana whakatūpatotanga haumaru. Rawa e tiaki ki te tiaki i te pūnaha romahā me te kiri.
