Potasiuma dichromate - physicochemical waiwai a me ke kahua o ka palapala noi

Potasiuma dichromate o kaʻoi loa ole-caking alani nā pōaka (kekahi manawa ike nae) a e hooholo koke wailana ma koʻana koko meakino, a ua hoʻokino e like me ka maalea paipu a me na papa. I ka interacting ana me ka waiwai koʻana koko pāʻoihana iʻakika.

Potasiuma dichromate - nuiʻawahia, carcinogen a me ka ikaika oxidants. ʻehu pāʻoihana e lukuʻili, cartilage, a me ka inhalation o ka ohu - Hawaiian Airlines.

I ka wela o ka ma kahi o 1300 ° C like me ka hopena o ka wehe aʻe naoh o ka paʻakai dichromate a me ka potasiuma koloriside ua hoomakaukauia potasiuma dichromate, K ₂ Kr ₂ O ₇ kona _haʻilula:

2KCl + Na ₂ Kr ₂ O ₇ → K ₂ Kr ₂ O ₇ + 2NaCl.

Keia waiwai ua hoʻohana 'ia i loko o ka hana. Kōmike potasiuma bichromate ua hoʻohana 'ia no ka? Iecaianoaaiiie o ihoiho maloʻo iuo aaoa?,'okanikaʻole pigments, HW ka paleʻana e like me ka ke aloha hoʻololi kemikala - e loaa nāʻano likeʻole o Nine Inch i huiʻia.

Red-melemele pāʻoihana o ke potasiuma dichromate kohu. Litmus pale ula waihoʻoluʻu. I hou reflux ka Nine Inch pāʻoihana i ke ano pouli-ula waihoʻoluʻu. A hiki i ka mahana i 398 ^e C potasiuma dichromate ka heheʻe, a huli i ka wai o ka pouliʻeleʻele kala like 'ole, a ma hope iho ka huʻihuʻiʻana solidifies a crystallizes. Luna 500 ^e C ka waiwai a ua pau loa ia i ka decomposed o oxygen ho okumu, chromium'okesaside a me ka potasiuma chromate.

Physicochemical waiwai o ka potasiuma dichromate

Pūnaewele a me ka amo ana o Nine Inch waiwai o kiʻekiʻe p ÷ ino ka papa

Kōmike potasiuma dichromate hiki e kaʻi aku e kekahi lānai o amo, koe wale no ka ea. Nine, piha i kūikawā ipu manao no kekahi-manawa hoʻohana, e hiki ke hele i hamama alahao ape kumukuai. Kōmike potasiuma dichromate pono e waiho i ka maloo pūnaewele iauaeoia, oiai o ka huina hoonui ma ka hana kūikawā ipu hookahi mākaʻikaʻi hiki ke waiho i loko o ka wehe lewa, i hoʻolako pono me ka paakiki ka penaʻana i ka wai runoff.

'ōpala o Nine Inch e pili ana i ka papa mua o p ÷ ino

Kōmike potasiuma dichromate ua pūʻolo helu i pela papahana kila pahu e like me ea mauʻeke, oia hoi o ka elima papa, he 50 kg. Aeia mai piha i pahee ipu, keia no hookahi ana.

Kau i ka papa o ka pilikia no ka Nine Inch

Kōmike potasiuma dichromate Naita me ia a me ke ahi p ÷ ino. Ke degere o ka ole ma ka kanaka kino ia mua p ÷ ino ka papa ua hāʻawi. I ka hana ana me ka Nine Inch pono e malama maluhia, e loa manao a me ka hooikaika, a e hoopili PPE ili a me ka ÷ naehana hanu nā loko.
