The critical surface tension, coarse degree and the oil ink adhesive force of plastics were improved, so the print adaptability was improved.
使得塑料临界表面张力、粗糙度、印墨附着力得到提高，从而改善其印刷适性。
The role of surface treatment is to improve the film surface tension so that it is greater than the ink to the surface tension of the ink and the correct filmogen .
表面处理的作用是提高薄膜的表面张力，使其大于油墨的表面张力，从而达到油墨和薄膜材料的正确结合。
The results indicate that with the composite surfactant of OP and FSO, the surface tension of the gel ink can be adjusted to the appropriate value, and the viscosity stability is improved effectively.
结果表明：添加OP与FSO复配的表面活性剂不但可以将中性墨水的表面张力调节到适当范围，而且改善了中性墨水黏度的稳定性。
