摘要
分析了兴安落叶松树皮栲胶废渣的主要化学组分及各组分的磺化产物对木质素磺酸盐的表面活性的作用,发现树皮栲胶废渣制备的木质素磺酸盐表面活性、分散性能和净浆流动度较木材木质素磺酸盐高。表面活性和分散性能好的主要原因是栲胶废渣中可溶单宁和红粉的存在,而具有更好的净浆流动度是因为可溶单宁和酚酸的存在。
The chemical composition of the components from the waste of the larch bark tannin production and the surface activity of their sulfonated products were investigated. In comparison with the wood lignosulfonate, the higher surface activity and dispersity of the sulfonated product of waste from larch bark tannin prodution are originated from its tannin and phlobaphene components and the higher coment paste fluidity is due to the presence of tannin and phenolic acids.
