探讨了颜料涂布纸油墨吸收性的影响因素,结果表明,在一定的范围内,随着GCC量的增加,瓷土片状结构的有序性被打乱了,涂层的孔隙率增加,利于油墨的吸收性的增强;在瓷土/重钙的比例一定的情况下,随轻钙份数的增加,油墨的吸收性增加;随着胶乳用量的增加,涂层表面成膜性增强,孔隙率减少,油墨吸收性降低;涂料中加入一定的淀粉后,油墨的吸收性明显提高;涂布量的增加会使涂层的结构更加紧密,油墨的吸收性会随着涂布量的增加而降低。但是涂布量的增加,条痕等纸病会带来油墨吸收性的升高。
The factors that affect the ink absorbency of pigment coated paper were discussed. The results showed that the orderliness of the flaky structure of porcelain clay was disrupted in a certain range with the increase of GCC, and the porosity of the coating increased, The absorptivity of the ink is enhanced; the absorption of the ink increases with the increase of the proportion of the light calcium under the certain proportion of the clay / gypsum; with the increase of the amount of the latex, the film-forming property of the coating increases, the porosity Reduce the ink absorption reduced; adding a certain amount of starch paint, ink absorption significantly increased; coating amount will make the coating more compact structure, the ink absorbency will be reduced with the coating amount increases . However, an increase in the amount of coating, streaks and other paper diseases will lead to increased ink absorption.
