摘要
通过对脲醛树脂的合成改性,降低了树脂中游离甲醛含量,减小了毒性,加入改性剂后增加了树脂韧性。改性脲醛树脂用于防砂,成本低、地面粘度小、可泵性好、施工操作方便,固砂后强度、渗透率均较高,有一定的应用前景。现场应用取得了很好的防砂效果。
Free formaldehyde content in resin is reduced through beetle modification, and the toxicity is thus reduced. The toughness of resin has been increased after adding modifier. When using beetle for sand control, the cost is low, surface viscosity is low, pumpability is good, operation is simple, and both the strength and permeability after sand consolidation are high. It has achieved good field application result.
