In this paper the performance and mechanism of AE superplasticizer GCL1-D,which is developed by modification of lignosulphonate,is studied. 试验研究了木质素系高性能引气减水剂GCL1-D对砂浆及混凝土应用性能的影响,并初步探索其作用机理。
ZL and lignosulphonate calcium don't harm the strength development of granular soil stabilized with cement. ZL和木钙两种缓凝剂对水泥稳定粒料土的强度发展无不良影响。
When the effect of ZL and lignosulphonate calcium is nearly same,ZL is more economical and applicable than lignosulphonate calcium. 在效果相近时，ZL比木钙更加经济适用。
Liquid paraffin is proposed as anti-oxident for dry-charged plates because of its good charge acceptance when combined with sodium lignosulphonate. 介绍了几种负极极板的典型配方,建议在干荷电极板中使用液体石蜡为防氧化剂,它能与木素磺酸钠匹配,有良好的充电接受能力。
The lignosulphonate is the waste residue in papermaking industry, and discharges abundantly every year, and its valid utilization is small quantity. 磺酸盐木质素是造纸工业的废渣，每年排出的数量巨大，而被利用的仅是很小的一部分。
