The modified larch bark tannin extracts can be used in production of bakelite bond 可应用于酚醛树脂绝缘板的黏合剂生产。
Studies on physical and chemical properties of lignosulfonate from dahurian larch bark residue after extraction 落叶松栲胶废渣木质素磺酸盐理化性能的研究
The high sulfitated larch bark tannin extracts are more available to decrease the solution viscosity than the alkali treated extracts 高度亚硫酸化的改性落叶松栲胶相比碱处理的改性落叶松栲胶更有效地降低其黏度和相对分子质量。
This paper illustrates the reaction of larch bark tannin extracts with sulfite and sodium hydroxide and the tests of its solution viscosity , mw - distribution and thin - layer chromatography 摘要通过对落叶松栲胶进行亚硫酸盐和氢氧化钠的改性,则定其溶液黏度,用不同溶剂进行分级和薄层色谱。
