Mutengesi weSodium Dichromate muSouth Africa

Chii chinonzi Sodium Dichromate?

Sodium dichromate (Na₂Cr₂O₇) munyu wechromium une hexavalent inonyungudika mumvura, unounzwa semakristaro akajeka-orenji-tsvuku kana semusanganiswa we dihydrate. Ndiyo imwe yemakemikari echromium anoshandiswa zvakanyanya mumaindasitiri, inoshanda senzira yekuvandudza chromic acid, inhibitor ye corrosion, uye ine simba re oxidizing agent. Kunyungudika kwayo mumvura yakawanda uye huwandu hweCr(VI) hunoita kuti ive yakakosha muzvikamu zvakasiyana-siyana zvekugadzira.

Dziviriro yeChromating & Kuora

Sodium dichromate chinhu chikuru mu chromate conversion coating solutions inoshandiswa kune zinc, aluminium, cadmium, uye magnesium substrates. Aya ma layer epassivation anopa simba rekudzivirira ngura uye anoshanda senzira yekunamatira kune mamwe masystem ependi. Muzvikamu zvemotokari nendege, nzvimbo dzakagadziriswa chromate dzinowedzera hupenyu hwebasa rezvikamu.

Kuchenesa Dehwe & Machira

Kuchenesa ganda uchishandisa sodium dichromate-derived chromium sulfate ndiyo nzira inonyanya kushandiswa pakuchenesa ganda pasi rose, ichigadzira matehwe akapfava, asingapindi mvura anoshandiswa mushangu, upholstery, uye mbatya. Mumachira, sodium dichromate inoshanda semushonga unonamira, ichibatanidza madhayi kune faibha dzechisikigo dzakadai semvere dzemakwai. Maindasitiri ematehwe nemachira muSouthern Africa anovimba nekuwaniswa kwemunyu wechromium nguva dzose kuti arambe achigadzirwa.

Kugadzirwa kwemakemikari & Oxidation yeindasitiri

Sechinokonzera oxidant chakasimba, sodium dichromate inoshandiswa mukugadzirwa kwe chromium pigments, chromium sulfate, nemamwe makemikari e chromium. Inoderedza organic compounds mu batch reactions uye inoshanda sepakati mukugadzirwa kwe chromium oxide green pigments. Magwaro ekutevedzera mitemo anopiwa pamwe chete nepese panowanikwa kuti abatsire vashandisi kusangana nemiganhu yekusvibiswa pabasa uye zvinodiwa pakugadzirisa marara.
