Fine particle detachment and subsequent migration can lead to severe pore plugging and consequent permeability decline. Therefore, it is crucial to quantify the critical condition when fine particle detachment occurs. The frequently observed deviations or even contradictions between experimental results and theoretical predictions of fines detachment arise from an insufficient understanding of adhesion force that can be highly influenced by salinity and temperature. To clarify the intrinsic influence of salinity and temperature on fines detachment, adhesion forces between carboxyl microspheres and hydrophilic silica substrates in an aqueous medium were measured at various salinities and temperatures using atomic force microscopy(AFM). The AFM-measured adhesion force decreases with increasing salinity or temperature. Trends of mean measured adhesion forces with temperature and salinity were compared with the DLVO and XDLVO theories. DLVO theory captured the trend with temperature via the impact of temperature on electric double layer interactions, whereas XDLVO theory captured the observed trend with salinity via the impact of salinity on the repulsive hydration force. Our results highlight the significance of hydration force in accurately predicting the fate of fines in porous media.

改革开放之初,中共中央对工会工作的指导方针发生重大转变,提出工会组织应建设成为“职工之家”。为此,1984—1987年,中华全国总工会领导开展了“整顿工会基层组织,建设‘职工之家’”活动,简称“整顿建家”。“整顿建家”活动以工会系统的基本恢复为基础,历经三个发展阶段,即由基层探索上升为顶层设计的探索启动阶段、自上而下逐级推进的全面展开阶段和走向全方位建设的深入发展阶段,期间中华全国总工会发挥重要领导和推动作用,基层工会工作面貌也焕然一新。通过“整顿建家”,基层工会组织建设全面加强,职工群众积极参与企业改革和各项体制改革,对工会工作满意度显著提升,建设“职工之家”也成为工会的一项常态化工作。“整顿建家”是工会40多年建家历史的“开创者”,其坚持普遍性与特殊性相统一的原则对当下工会建家工作仍有借鉴意义。
