聚乙烯醇

The results show sheafing strength of wood glued-product produced by adhesive prepared with the optimal formulation of six starch-based API wood adhesive can completely meet requirement of JIS K6806 and each property indices of adhesive satisfy demand for the practical process technology.

其次，以复合变性玉米淀粉、乙二酸、聚乙烯醇、P-MDI为影响因素，按照日本JIS K6806标准中关于水性高分子-异氰酸酯木材胶粘剂胶接木材时的不同耐水性要求，通过正交试验，分别优化出Ⅰ型、Ⅱ型中Ⅰ、Ⅱ类的常态胶接、热水浸渍、反复煮沸胶接强度的六种淀粉基API的配方，并在对实验结果进行了验证性试验的基础上，进行了工业化生产试验。

The PVA could help CNTs weltering the aquatic phase and enhance the stability of their dispersion. The PVA had bifunctional bridges, with hydrophilic groups jointed with the Fe2O3 film, and hydrophobic chains adhered to the surface of the carbon nanotubes, so the Fe2O3 were supported on the surface of the carbon nanotubes through the surfactant.
