Sodiumcarbonate CAS: 497-19-8

Sodium carbonate muaj ntau yam kev siv thoob plaws ntau yam lag luam. Hauv kev tsim khoom, nws feem ntau yog siv rau hauv kev tsim iav, tshuaj ntxuav tais diav, thiab tshuaj lom neeg. Hauv kev lag luam iav, sodium carbonate ua haujlwm ua cov kua dej, txo qhov melting point ntawm silica thiab pab txhawb kev tsim iav. Nws kuj pab tswj cov pH thiab viscosity ntawm cov iav molten, xyuas kom meej cov khoom xav tau hauv cov khoom kawg. Ntxiv mus, sodium carbonate yog ib qho khoom xyaw tseem ceeb hauv kev tsim cov tshuaj ntxuav tais diav thiab cov neeg sawv cev ntxuav. Nws cov khoom alkaline ua rau nws ua haujlwm zoo hauv kev rhuav tshem thiab tshem tawm cov roj, cov xim, thiab cov av ntawm cov nplaim. Hauv cov tshuaj ntxuav khaub ncaws, nws pab ua kom dej mos, txhim kho kev ntxuav ntawm cov mis. Tsis tas li ntawd, sodium carbonate yog siv rau hauv cov tshuaj ntxuav hauv tsev, cov tshuaj ntxuav tais diav, thiab cov tshuaj ntxuav roj rau nws cov haujlwm ntxuav muaj zog. Hauv kev tsim tshuaj lom neeg, sodium carbonate ua haujlwm ua ntej hauv kev tsim ntau yam tshuaj lom neeg thiab cov khoom sib xyaw. Nws koom nrog hauv kev tsim cov sodium bicarbonate (baking soda), sodium silicate, thiab sodium phosphates, uas pom cov ntawv thov hauv kev ua zaub mov, kev kho dej, thiab tshuaj. Ntxiv mus, sodium carbonate yog siv rau hauv cov txheej txheem kho dej rau kev kho pH thiab ua tus neeg sawv cev buffering. Nws kuj siv rau hauv kev lag luam textile rau kev zas xim thiab pH kev tswj hwm hauv kev ua cov fibers thiab ntaub. Zuag qhia tag nrho, sodium carbonate qhov kev hloov pauv thiab cov khoom siv tshuaj lom neeg ua rau nws yog ib qho tseem ceeb hauv kev lag luam xws li kev tsim iav, kev tsim tshuaj ntxuav tes, kev tsim tshuaj lom neeg, kev kho dej, thiab textiles, ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv thiab cov txheej txheem.
