style="text-indent:25px">色素炭黑是塑料的著色劑、防紫外線老化劑和抗靜電劑。隨著塑料行業(yè)的發(fā)展，炭黑在塑料行業(yè)的用量也越來(lái)越大，從普通的日用塑料到***的工程塑料都離不開(kāi)炭黑。用量雖然不多，但它對(duì)塑料性能的影響很大，因此，對(duì)塑料用炭黑的性能要求更加嚴(yán)格，不同用途的塑料制品對(duì)炭黑性能有不同的要求，為降低塑料的成本，炭黑的用量要求盡可能地高，但是，研磨設(shè)備的性能和類型將對(duì)炭黑的分散產(chǎn)生重要的影響。不同的塑料要求不同的分散水平。在許多情況下，塑料性能的不足可以直接歸因于炭黑分散的不足，如電纜外殼和光纖等塑料產(chǎn)品，要求炭黑的分散水平能達(dá)到更高層次。對(duì)于性能要求很高的塑料，炭黑的充分分散是非常重要的。如果能提高色素炭黑的分散水平，可以使塑料的顏色、色相、粘度、光澤、穩(wěn)定性以及擠出特性等達(dá)到更好的要求。</p><p style="text-indent:25px">絲印油墨炭黑越黑，其酸性值也較高，PH值約在2.5 ~
