摘要

通过测试不同黄麻纤维含量的涂料在100～800℃的透气性

研究了黄麻纤维对真空实型铸造涂料透气性的影响。发现加入0.2%和0.5%黄麻纤维时

涂料透气性在400～600℃之间快速上升

600℃以后分别稳定在5.8～6.3和9.8～10.6cm4.g-1.min-1。结果表明

真空实型铸造涂料的透气性可通过黄麻纤维的含量调节。

Abstract

Effects of the jute fiber on the permeability of coating for vacuum-expandable pattern casting were examined by measuring permeability of the coating with different jute fiber content at 100

00 ℃.It is found that with 0.2% and 0.5% jute fiber content

the permeability of coating is raised sharply at 400

00℃ and it keeps stable value of 5.8

.3 cm4·g-1·min-1 and 9.8

0.6 cm4·g-1·min-1.The results exhibit that addition of jute fiber can affect permeability of coating for vacuum-expandable pattern casting.
