摘要
炭黑分为酸性色素炭黑和中性炭黑.色素炭黑具有比较好的抗凝胶能力,而中性炭黑必须用抗凝剂六偏磷酸钠、扩散剂NNO、阳离子表面活性剂1231 Br进行表面处理,并把pH值调配到微酸性,以解决涂料印花炭黑遇丙烯酸型合成增稠剂会产生凝胶的问题.
The carbon black can be divided into acidic pigment carbon the formal has good anti-gelling capability. The neutral one must be treate sodium hexametaphosphorate, dispersant NNO and cationic surfactant 1231 black and neutral carbon black and d with anti-gelling agents such as Br, followed by adjusting to weakly acidic one, thus to avoid the gelling problem happening when the pigment printing carbon black meets the acrylic synthetic thickeners.
