醇基涂料性能的研究现状

醇基涂料可以满足铸造性能要求而得到广泛应用,将复合悬浮剂和新型纳米分散剂加入到醇基涂料中是近年来的研究热点。介绍了醇基涂料的工艺性能以及工作性能方面的研究现状,指出了提高醇基涂料悬浮性和透气性的具体方法:采用加入更有效的悬浮剂和控制制备工艺两种方法来提高醇基涂料的悬浮性;涂料透气性的影响因素主要有耐火骨料的形状和粒度,在铸造浇注的恶劣条件下,耐火骨料的变化以及黏结剂的分解使得涂料的高温透气性不同于低温透气性,将有机黏结剂与无机黏结剂混合使用是醇基涂料黏结剂的发展趋势,加入纤维状耐火骨料提高涂料强度是今后的重要研究方向。     

Affective commitment,home-based working and the blurring of work–home boundaries: Evidence from Germany

Analysis of data from the representative German Linked Personnel Panel revealed that, overall, the use of home-based working is associated with a higher affective organisational commitment on the part of employees. However, this is less often the case when the use of home-based working involves the blurring of work–home boundaries. Perceived trust and fairness on the part of supervisors mediates the association between employees' experiences with working from home and their affective commitment. These results show that experiences with home-based working shape employees' perceptions of trust and fairness in their exchange relations with supervisors and thus their affective commitment to the organisation. Employees' experiences with home-based working that reflect its supportive implementation by their employers and supervisors are critical for their commitment. Our results provide the first evidence that in exchange relations between employees and supervisors, perceived fairness is as important as perceived trust.
