Sodium Chromateyog ib qho tshuaj sib xyaw nrog cov tsos ntawm cov xim tsis muaj xim lossis lub teeb daj, CAS tus lej 7775-11-3, tshuaj formula CrNa₂O₄, molecular hnyav 161.97324. Nws yog ib qho muaj zog oxidant uas reacts nrog txo cov neeg ua haujlwm thiab tuaj yeem ua rau cov kua qaub los tsim chromic acid.
Sodium Chromate
Sodium Chromate muaj ntau yam kev siv:
1. Kev lag luam teb
- Hlau nto kho: feem ntau siv rau xeb thiab corrosion tiv thaiv ntawm hlau. Nws tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau saum npoo los tiv thaiv cov pa oxygen, dej thiab lwm yam corrosive los ntawm kev sib cuag nrog cov hlau, yog li ua kom qeeb ntawm corrosion ntawm cov hlau thiab ua rau kev pab cuam lub neej ntawm cov khoom hlau.
- Kev lag luam tanning: Nws yog ib qho tseem ceeb pab tus neeg sawv cev hauv cov txheej txheem tawv tanning. Nws tuaj yeem ua ke nrog collagen hauv tawv los kho thiab ntxiv dag zog rau cov qauv tawv, ua rau tawv nqaij muaj zog zoo dua, hnav tsis kam thiab dej tsis kam, thaum tseem txhim kho qhov kev xav thiab pom ntawm tawv.
- Kev lag luam luam ntawv thiab dyeing: siv los ua mordant, nws tuaj yeem pab cov dyes ua raws li cov ntaub ntawv zoo dua, txhim kho cov nyhuv dyeing, ua kom dyeing ntau uniform, ruaj, thiab ci dua xim.
2. Chemical teb
- Chemical synthesis: Nws yog ib qho tseem ceeb raw khoom rau kev npaj ntawm lwm cov chromium tebchaw, xws li sodium dichromate, chromic anhydride, thiab lwm yam. Los ntawm reacting nrog txawv reagents, nws yuav hloov mus rau ntau yam chromium tebchaw nrog kev siv tshwj xeeb. Cov tebchaw no tau siv dav hauv tshuaj, electroplating, pigment thiab lwm yam lag luam.
- Catalyst: Nws tuaj yeem siv los ua cov catalyst lossis cov khoom siv ntawm cov catalyst hauv qee cov tshuaj lom neeg cov tshuaj tiv thaiv, uas tuaj yeem ua kom cov tshuaj tiv thaiv sai thiab txhim kho cov kev xaiv thiab cov txiaj ntsig ntawm cov tshuaj tiv thaiv.
3. Lwm qhov chaw
- Kev Kho Mob: Sodium Chromate tuaj yeem siv los npaj qee cov tshuaj nruab nrab, uas yog cov ntaub ntawv tseem ceeb rau kev sib txuas cov tshuaj tua kab mob, cov vitamins thiab lwm yam tshuaj.
- Kev kho dej: Hauv kev kho dej, Sodium Chromate tuaj yeem siv los ua cov tshuaj tiv thaiv corrosion los tiv thaiv corrosion ntawm cov khoom siv hlau thiab cov kav dej hauv dej. Nws kuj tuaj yeem ua rau qee qhov impurities hauv dej kom huv dej kom zoo. Txawm li cas los xij, nws muaj qee yam toxicity, thiab nws daim ntawv thov hauv kev kho dej yog nyob rau qee qhov kev txwv, thiab nws cov kev siv thiab kev tawm yuav tsum tau tswj nruj me ntsis.
Gneebionrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav teb.
