The objective of the government-funded research project “SiLat” (Simulation der instationären Lacktrocknung bei dreidimensionalen Objekten—simulation of paint drying processes on three-dimensionally shaped geometries) is the development of a CFD-software simulation add-on for the drying process of paints [11]. The software is intended to be used in the automotive industry to predict the intermediate drying process of water based paints on car bodies in continuous convective dryers. To validate the software, several laboratory scale experiments, using industrial water-based paint systems and a model base paint system applied on a sheet of metal, were carried out. Conditioned air was used for the drying process. The experimental setup was varied in three different ways: paint on a flat sheet was dried in impinging jet and parallel flow conditions. Furthermore, a Z-shaped sheet was dried during parallel flow conditions. Additional experiments were performed varying the flow parameters. During all experiments, the sheet temperature and weight of the painted sheet were monitored with a rate of 1 Hz. The evaporation of the organic solvents could be monitored using FTIR-spectroscopy. This contribution deals with the experimental investigations and simulation results, whereas the paint drying model is presented by Domnick et al. [5] in detail. 相似文献

Among the numerous publications analyzing the causes and consequences of titanium dioxide crowding on the optical properties
of white paint films, one notes some inconsistencies. First, a significant number of studies are inclined to describe “dependent”
and “multiple” scattering of light as distinct phenomena. Second, the transition from independent to dependent light-scattering
is often associated with an ill-defined “threshold” concentration. The aim of this study is to clarify the intricate connections
between these two scattering regimes and in particular to show that for white paint films loaded with rutile titanium dioxide
pigments, “dependent” light scattering is merely a particular manifestation of multiple scattering processes. We also clarify
that the transition from independent to dependent scattering is a continuous process that cannot be formally related to a
specific threshold in the pigment volume concentration. Finally, we propose a simple method based on the dependent scattering amplitude to assist paint formulators facing the task of improving the hiding power of a white paint either by
increasing the quantity of pigments or by improving their spatial state of dispersion. 相似文献

海洋石油平台涂装工程涂料损耗分析 总被引:1,自引:0,他引:1
涂料的损耗控制一直都是涂装施工的重要环节,由于造成损耗的因素过多,设计方、施工方、涂料制造商都很难精确地计算损耗系数,很不利于施工管理和成本控制。海洋工程是个新兴的产业,施工中涂料的损耗常借鉴造船行业的经验,但由于二者在涂装工艺、结构、涂装设备等方面存在着很大的不同,导致损耗的差别很大。通过对国内石油行业多个海洋石油平台的涂装工程施工,积累了海洋工程涂料的使用数据,对影响涂料损耗的表面粗糙度、涂装方式、钢结构的几何形状、操作技术、环境因素、涂料浪费、修补等各项因素进行分析,尝试对涂料的损耗系数进行精确的统计。通过制定减少损耗的措施,在施工中严格控制,保证了新建海洋石油平台的涂料损耗系数控制在1.0~1.5之间,使涂料损耗达到了比较精准的控制。 相似文献
