Daim ntawv thov teb ntawm Sodium Cyanide
Sodium cyanide yog ib qho tseem ceeb ntawm cov tshuaj raw khoom, uas yog siv rau hauv cov tshuaj synthesis, electroplating, metallurgy thiab organic synthesis ntawm tshuaj, tshuaj tua kab thiab kev kho hlau. Complexing agent, masking agent. Kub thiab nyiaj thiab lwm yam muaj nuj nqis hlau refining thiab electroplating, thiab lwm yam.
Nws yog siv los ua tus neeg sawv cev quenching rau ntau yam steels hauv kev lag luam machinery.
Hauv kev lag luam electroplating, nws yog siv los ua cov khoom tseem ceeb ntawm tooj liab, nyiaj, cadmium thiab zinc plating. Nyob rau hauv cov tshuaj electroplating, nws tuaj yeem txo qhov polarization ntawm anode, xyuas kom meej qhov kev sib cais ntawm cov anode, stabilizing cov txheej txheem plating thiab txhim kho cov polarization ntawm cathode kom tau txais cov txheej txheem sib xws.
Hauv kev lag luam metallurgical, nws yog siv los rho tawm cov hlau zoo li kub thiab nyiaj.
Hauv kev lag luam tshuaj, nws yog cov khoom siv raw rau kev tsim khoom ntawm ntau yam inorganic cyanides thiab hydrocyanic acid, thiab tseem siv rau kev tsim cov plexiglass, ntau yam khoom siv hluavtaws, nitrile roj hmab, thiab copolymer ntawm hluavtaws fibers.
Hauv kev lag luam dyeing, nws yog siv los tsim cyanuric chloride (reactive dye intermediate, thiab raw khoom rau zus tau tej cov whitening agent). [2]
Hauv kev lag luam kws tshuaj, nws yog siv los tsim methyl cyanoacetate thiab diethyl malonate, thiab lwm yam. Nws yog siv los ua mordant hauv kev lag luam textile, thiab kuj siv rau hauv cov kua carburizing thiab nitriding hlau.
Qhov tseem ceeb inorganic cyanides uas tsim ncaj qha los ntawm sodium cyanide feem ntau suav nrog cov ntshav daj ntsev sodium, ntshav daj ntsev potassium, potassium cyanide, zinc cyanide, barium cyanide, cuprous cyanide, sodium thiocyanide, thiab potassium cyanide; Organic cyanides muaj xws li cyanoacetic acid, malononitrile, methionine, cyanobenzyl, thiab cyanuric chloride. Cov khoom tseem ceeb ntawm hydrogen cyanide regeneration siv sodium cyanide yog: methyl methacrylate, butyl methacrylate, methacrylic acid, azobisisobutyronitrile, azobisisoheptanonitrile, nitrilotriacetic acid, hydroxy Acetonitrile thiab lwm yam.
