一、前言以木质素磺酸钙为主剂配制成的某些化学灌浆浆液(如铬木素、铬渣木素、木铵等)易产生泡沫。而在实际防渗、堵漏工程应用中,浆液发泡会带来许多不利因素,如1、影响精确的进浆计量;2、泡沫隔热性好,浆液的反应热一部分不易从液面散发,致使浆液增粘加快,影响浆液的可灌性;3、由于泡沫存在于液面,使液位不易看清,容易将泡沫,甚至空气压入 I. INTRODUCTION Certain chemical grout slurries (such as chromium lignin, chromium slag lignin, wood ammonium, etc.) formulated with calcium lignosulfonate as the main agent are prone to foam. In the actual anti-seepage, plugging engineering applications, the slurry will bring a lot of unfavorable factors, such as 1, affect the precise measurement into the pulp; 2, foam insulation is good, the slurry heat of reaction is not easy to part of the liquid from the distribution , Resulting in thickening of the slurry to speed up, affecting the irrigation of the slurry; 3, due to the presence of foam in the liquid, so that the liquid level is not easy to see, easy to foam, or even air pressure
