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。
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 100~800 ℃.It is found that with 0.2% and 0.5% jute fiber content,the permeability of coating is raised sharply at 400~600℃ and it keeps stable value of 5.8~6.3 cm4·g-1·min-1 and 9.8~10.6 cm4·g-1·min-1.The results exhibit that addition of jute fiber can affect permeability of coating for vacuum-expandable pattern casting.
