3 )将流体浆料注入模具中,静置 1h ,完全固化成型得到半成品;
4 )将固化成型的半成品脱模后置于热水中侵泡 3h ,得到成品。
本发明制备的耐高压多孔高分子 PMMA 滤膜材料比重 1.05-1.12 ;抗压强度 25-28MPa ;抗折强度 13-15MPa ;成品收缩率小于 0.5% ;过水率大于 20% ;孔隙率 20-38% ;微孔径 0.01~12 μm ;特殊用途孔径 13 μm~80μm ; 透水性能优等。由于本发明的高分子过滤材料添加了可溶于 MMA 的高分子材料,聚合反应时聚合热产生的较少,因此不会产生爆聚现象,高分子材料不含有气泡,孔径均匀。
本发明制备的耐高压多孔高分子 PMMA 滤膜材料制备工艺简单、室温固化快及加热速固化、容易成型和加工;本发明的耐高压多孔高分子 PMMA 滤膜材料具有可以反复利用、材料质轻、机械强度高、耐冲击性好、耐高压、成型收缩小、透水性好、孔径可调的特点;可用于食用净水、环保、化工等水处理领域,也是食品、制药、国防军事等分离富集材料、过滤材料、透水材料等。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
