聚合物均质处理技术

Polymer Homogenization

In the preparation of polymer solution, polymer will be mixed with the appropriate solvent and stirred, it would be considered as dissolved completely if transparent polymer solution be observed. But polymer micro-gel is invisible by human eyes, it is very easy to cause abnormal quality problems of the finished product.

N seris ultra-high shear force can be used to replace or enhance the mixing operation of stirrers and conventional homogenizers. Better dispersion results can be obtained under the same formulation of polymer solution. Take multi-layer ceramic capacitor (MLCC) as an example, its polymer binder usually mixed with different polymers which with different molecular weights, it can be observed that viscosity of binder solution significantly reduced by high pressure homogenization process , meanwhile the residue of micro-gel particles can be reduced, conducive to preparation of ceramic powder paste (Slip) and thin film coating process, greatly improve the characteristics of the MLCC finished product.

In order to improve the dispersion characteristics of functional ceramic powders into the polymer solution (ceramic slurry). For example the packaging resin of luminescent devices, it can also be found that smaller average particle size and better particle size distribution after treatment of high- shear , conceive to better physical properties and excellent quality of finished products.

聚合物均质处理技术

在聚合物溶液制备过程中，聚合物与溶剂混合搅拌后若呈现透明状态常被误判为完全溶解。但人眼无法识别的聚合物微凝胶极易导致成品出现异常质量问题。

N系列高压微射流均质机的超高剪切力可替代或增强搅拌器和传统均质机的混合效果。在相同聚合物配方下能获得更优的分散效果。以多层陶瓷电容器（MLCC）为例，其聚合物粘结剂通常混合不同分子量的聚合物，经NanoLyzer高压均质处理后可见粘度显著降低，同时微凝胶颗粒残留减少，有利于陶瓷粉末浆料制备和薄膜涂层工艺，大幅提升MLCC成品特性。

对于功能陶瓷粉末在聚合物溶液（陶瓷浆料）中的分散特性改善，如发光器件的封装树脂，经高强度剪切力处理后同样可观察到平均粒径减小和粒径分布优化，最终获得更优异的物理特性和成品质量。
