Sodiumdicyanamide CAS: 1934-75-4

Sodium dicyanamide muaj ntau daim ntawv thov tseem ceeb thoob plaws ntau yam lag luam. Hauv kev lag luam organic synthesis, nws ua haujlwm ua tus neeg nruab nrab tseem ceeb hauv kev tsim cov tshuaj, cov xim, thiab cov tshuaj agrochemicals. Nws lub peev xwm los koom nrog ntau yam kev tshuaj tiv thaiv ua rau nws muaj txiaj ntsig zoo hauv kev tsim ntau yam organic sib xyaw. Hauv thaj chaw ntawm cov ntaub ntawv tshawb fawb, sodium dicyanamide yog siv los ua tus neeg sawv cev rau epoxy resins. Thaum ua ke nrog cov tshuaj epoxy, nws ua haujlwm ua tus neeg tawv, pab txhawb rau kev tsim cov txheej txheem ruaj khov, ua haujlwm siab thiab cov nplaum. Ntxiv mus, cov tshuaj no pom daim ntawv thov hauv kev tsim cov nplaim taws retardants, qhov twg nws pab txhim kho kev tiv thaiv hluav taws ntawm ntau yam khoom siv xws li yas, textiles, thiab cov khoom siv tsim kho. Nws kev koom ua ke rau hauv cov khoom no pab txo qhov kev pheej hmoo ntawm kev phom sij ntsig txog hluav taws. Hauv kev ua liaj ua teb, sodium dicyanamide ua haujlwm ua cov chiv nitrogen, muab cov nroj tsuag nrog cov as-ham tseem ceeb rau kev loj hlob thiab kev txhim kho. Nws cov yam ntxwv tso tawm tswj hwm ua rau nws tsim nyog rau kev ua kom ntev thiab pab tiv thaiv cov teeb meem ib puag ncig cuam tshuam nrog nitrogen leaching. Tsis tas li ntawd xwb, sodium dicyanamide siv rau hauv kev tsim cov guanidine compounds, uas muaj cov ntawv thov ua cov stabilizers hauv kev lag luam yas thiab ua cov khoom siv nruab nrab rau cov tshuaj thiab cov tshuaj tua kab. Ntxiv mus, nws ua lub luag haujlwm hauv cov txheej txheem electroplating, ua haujlwm ua cov khoom ntxiv hauv cov kua electrolyte los txhim kho qhov zoo thiab cov khoom ntawm cov txheej txheem hlau tso. Nws siv hauv electroplating pab txhawb kev txhim kho kev tiv thaiv corrosion thiab kev zoo nkauj ntawm ntau yam hlau nto. Zuag qhia tag nrho, sodium dicyanamide qhov kev hloov pauv thiab kev ua haujlwm ua rau nws yog ib qho khoom muaj nqis hauv kev tsim cov organic compounds, kev tsim cov ntaub ntawv nrog cov khoom tshwj xeeb, thiab kev txhim kho kev ua liaj ua teb. Nws cov ntawv thov sib txawv hauv kev tsim cov organic, cov ntaub ntawv tshawb fawb, kev nyab xeeb hluav taws, kev ua liaj ua teb, thiab electroplating qhia txog nws qhov tseem ceeb thoob plaws ntau yam kev lag luam.
