碳黑的著色力通常是用百分?jǐn)?shù)的形式來表現(xiàn)，可以通過使用黑度反射儀測(cè)量碳黑沖淡色漿得出的數(shù)據(jù)來衡量。根據(jù)工業(yè)標(biāo)準(zhǔn)操作，色漿為碳黑和鈦白 </p> <p> （或其他白色顏料如氧化鋅）及一定溶劑的混合物。 </p> <p> （著色力的測(cè)量參照 ASTM D-3849 或 GB/T7046-2003標(biāo)準(zhǔn)） </p> <p> 比表面積 </p> <p> 炭黑比表面積是指單位質(zhì)量或單位體積內(nèi)炭黑粒子表面積的總和，單位為m2/g 。比表面積與粒徑一樣是炭黑的基本性能之一。對(duì)表面光滑的炭黑來說，比表面積與粒徑成反比，即粒徑越小比表面積越大，反之亦然。所以，如把炭黑粒子假定為球形，可由粒徑的數(shù)據(jù)計(jì)算比表面積。橡膠用炭黑粒子表面一般是比較光滑的，無孔的。粒子較細(xì)的中超耐磨炭黑表面帶有少量微孔。色素炭黑由于生成條件或經(jīng)后處理，表面有一定程度氧化，粒子表面積大于相同粒徑的橡膠用炭黑。 </p> <p> 炭黑的比表面積分為外比表面積（或稱光滑比表面積），內(nèi)比表面積（或稱孔隙內(nèi)比表面積）和總比表面積?？偙缺砻娣e等于外比表面積和內(nèi)比表面積的總和。比表面積的測(cè)定方法很多，常用的有氮吸附法（BET法）,吸碘值法，CTAB法（大分子吸附 </p> <p> 法），t值法以及電子顯微鏡法等。上海俄羅斯碳黑銷售價(jià)格據(jù)分析，可在炭黑表面檢測(cè)如酚基、醌基、羧基等基團(tuán)，這些酸性基團(tuán)濃度在氣黑和氧化爐黑的表面特別高。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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 ~ 4.5之間，吸附能力越強(qiáng)，普通的絲印油墨炭黑PH值幾乎是中性的，因此其吸附能力不明顯。由于吸附能力對(duì)于涂料的干燥性有特殊影響，常因吸附色漆中的催干劑而使涂膜干率減退。PH值為4以下時(shí)，酸性越大，對(duì)催干劑的吸附能力也越大，則對(duì)抗干性能影響也就越明顯。色素炭黑的抗干作用，不是在制漆后立即表現(xiàn)出來，而是在完全或部分地對(duì)催干劑吸附后（貯存期內(nèi)），經(jīng)過一段時(shí)間才反應(yīng)出來。因此，在設(shè)計(jì)色漆配方時(shí)，要考慮適當(dāng)增加催干劑用量。 </p><p> 色素炭黑一般都能較好的給塑料著色，可根據(jù)著色特性或物化性能選用色素炭黑，著色用炭黑的品種的選擇基本上都是隨成品必須達(dá)到的黑度而定。用極細(xì)的色素炭黑可以完成黑度要求特別高的著色； PE垃圾袋，塑料袋，電纜材料之類產(chǎn)品只需中等水平黑度，可以用比表面積較低，結(jié)構(gòu)較高的炭黑品種；塑料調(diào)色時(shí)，炭黑稱量和配料時(shí)出現(xiàn)的微小誤差，均會(huì)導(dǎo)致明顯的色差，因此，宜采用粒徑較大，著色力較差的低色素炭黑，這樣炭黑用量可以稍大，稱量誤差相對(duì)小些，并有分散性較好、價(jià)格較低的優(yōu)點(diǎn)。
