铸造涂料流变特性对流淌性及流平性的影响
摘要

一、前言 流淌性是涂料涂刷后
在重力作用下所具有的流动趋势。流淌厉害的涂料会产生涂挂不均
涂层太薄
滴痕严重等缺陷。流平性是指涂料自行消除刷痕的能力。可见
流淌性和流平性都是与涂层质量密切相关的两个工艺性能。并同属剪切速率为0.1~1秒
-1
左右的低剪流变过程。 本文的目的在于研究涂料流变特性与流淌性和流平性的关系
并在此基础上提出评价这些性能的流变参数
为涂料的制备和应用提供科学依据。
Abstract
In this paper
the Theological correlation with leveling and sagging of mould coatings were studied . Using Casson pattern and based on experiments
rheological parameters are presented to evaluate the leveling and sagging of mould coatings quantitatively. Scientific facts and ways were supplied for preparation and application of mould coatings.
