油墨

Based on the basic theories of high-molecular physics and chemistry,colloid and surface chemistry, and from a microcosmic point of view, this ps-per provides a deep research on the major factors that affect color losing ofoffset ink such as ink dispersion, viscosity, desiccate and adhesiveness. Theauthor hopes to provide theoretica1 basis for solving the prob1em of color los-ing.

本文根据高分子物理化学、胶体与表面化学等理论知识，从微观角度深入分析了影响胶印油墨掉色的主要因素，如油墨的分散、粘性、干燥、粘附性等性能，从而为解决掉色问题提供理论依据。

In order to ensure there are enough small thickness, you should choose good homogeneity and diffusibility envirogluvtm, and note that the business card printing and membership card making ink and business card printing and membership card making substrate of the match performance.

为保证有足够小的厚度，应选择均匀性和扩散性好的油墨，并注意制卡和会员卡制作油墨与制卡和会员卡制作承印物的匹配性能。

Select ink drying rate of the general principle is that the business card printing and membership card making machine existing conditions, the ink in the next business card printing and membership card before making color group and their architecture to volume or stack should be able to fully dry before, but in the plate but not dry.

选择油墨干燥速度的一般原则是：在制卡和会员卡制作机现有的条件下，油墨在进行下一制卡和会员卡制作色组之前及进行复卷或堆叠之前应该能够充分干燥，但是在印版上却不能干燥。

The gravure business card printing and membership card deposit produced very thick (intaglio business card printing and membership card making ink film thickness is 9-20 μm, lithography business card printing and membership card making ink film thickness is only about 4 μm), the oxidation of trabeculectomies impossible to achieve quick-drying purpose gravure printing ink most fast with high volatility of drying oil based ink.

而凹版制卡和会员卡制作的墨层又十分厚实（凹版制卡和会员卡制作墨膜厚度一般为9-20μm，平版制卡和会员卡制作墨膜厚度仅为4μm左右），单靠氧化结膜无法达到快干目的，所以凹印油墨大多数采用高挥发快干性油墨。

In order for the business card printing and membership card making ink work well to a substrate on the surface, substrate Diane value should be higher than all of the ink of higher value by 10 Dyne.

为了使制卡和会员卡制作油墨不妨很好不天附着在承印物暗不天上，承印物的达因值不该比所有油墨的达因值矮不入10个达因。

According to the reflect characteristics of light and viscidity equation of Einstein,the influence of foil shape on the viscidity and luster of new metallic ink were studied.

根据光反射特点和爱因斯坦粘度方程，研究了颗粒形状与油墨的金属光泽和油墨粘度的关系，结果表明，长片状的金属颗粒能得到最好的印刷效果。

Too many in emulsibility in printing ink, when in the monlchamus membrane exposure split, water drops, which drops of ink to the paper to hinder.

过多的润版液在油墨中乳化，当墨膜分裂后，水滴暴露，这些水滴阻碍油墨向纸上传递。

In the business card printing and membership card manufacturing process, with water roll has to come into contact with the surface of the plate, offsctdruckereien use water out ink will be emulsibility emulsive, is a small amount of ink by water roll, to water roll, conspiracy water roller slot passed into the bucket, so no doubt about it to say that the water in the water roll chemiluminscent set must be kept clean, from oil pollution.

在制卡和会员卡制作过程中，着水辊都要接触印版表面，胶印使用水就决定了油墨将被乳化，被乳化的少量油墨通过着水辊、传水辊、串水辊传递到水斗槽里边来，所以说，水辊的水绒套必须保持清洁，不沾油污。

The reasons: first, the ink dry slowly tends to be a result of the slow evaporation rate of water, usually as a result of viscidity exorbitance or monochamus version xuetie deep and too thick membrane or for non-absorbent plastic, aluminum foil, and so on do not absorb ink, the other is for full wind conditions or no drying equipment condition or drying (including infrared small magnetic dry power) caused by the temperature low and so on.

原因：一是油墨干燥慢往往是因水的蒸发速率慢引起的，通常也会因粘度过高或版穴深而墨膜过厚或因非吸收性塑料，铝箔等不吸收油墨导致的，二是因完全无风状态下或无烘干设备条件或烘干(包括红外磁波干燥功率小)温度低造成的等等。

Its six is the basis for the ink system of resin, dissolved hydrogen bonds and softening point to estimate business card printing and membership card making ink adhesion of prefilming and flexility and wear-resistant, thermotolerance.

其六是依据油墨体系的树脂，溶解氢键力和软化点，可以估计制卡和会员卡制作油墨成膜后的附着力及柔韧性和耐磨、耐热性。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
