【摘要】 中性亚硫酸铵法蒸煮过程中,加用不同的缓蚀剂——氢氧化钠、氧化镁或碳铰,可以减轻对设备的腐蚀.采用电化学方法对比研究了三种缓蚀剂的缓蚀性能.对于不同条件下成浆的物理性能以及在制浆过程中脱木素的历程也进行了探讨。更多还原

【Abstract】 In order to alleviate the corrosion of cooking liquor to equipment,some buffering agents usually are added into the cooking liquors in the neutral ammonium sulfite process.The buffering effects of three buffering agents NaOH, （NH₄）₂CO₃ and MgO were investigated by a test based on the anodic polarization curve of digester made from car- bon steel.The research results show that in the cooking temperature from 80 to 140℃,the corrosion is an active portion,passive current reaching the maximum value.The buffering effect of 2%（NH₄）₂CO₃ is better.Their influ- ence on delignification courses and pulp properties were also studied.更多还原
