style="text-indent:25px">黑度黑度是指炭黑所具有的黑色呈現(xiàn)強(qiáng)度。炭黑作著色時，黑度主要基于對光的吸收，對于特定濃度的炭黑，炭黑越細(xì)小，則光吸收程度越高。黑度除了受炭黑內(nèi)部的光吸收外，也受由于粒子表面幾何機(jī)構(gòu)的影響而產(chǎn)生了具有增亮效應(yīng)的光散射，這會降低黑度。隨著粒徑的減小，光散射程度降低。只有對于很細(xì)的炭黑，提高炭黑的濃度才能提高黑度，對于粗大的炭黑，具支配因素的光散射程度因炭黑數(shù)增加而提高，黑度反而相應(yīng)降低。著色強(qiáng)度著色強(qiáng)度可以理解為抵消白色顏料增白能力的效果。著色強(qiáng)度也是隨著原生粒子的粒徑減小和結(jié)構(gòu)的減小而提高。上?？ú┨靥己谪浽闯渥泐伭虾谧鳛樽贤夤馕談?，主要用作延長塑料制品在戶外使用壽命。</p><div

style="text-indent:25px">分散性顏料黑越細(xì)，炭黑聚集體之間接觸點(diǎn)便越多，結(jié)果它們之間內(nèi)聚力越強(qiáng)，當(dāng)把顏料黑摻入料，即開始進(jìn)行始炭黑均勻分布時，則對分散要作的功便大，以把炭黑粒子分隔開來，**終達(dá)到比較高的黑度和著色。與高結(jié)構(gòu)炭黑相比，低結(jié)構(gòu)炭黑較有可能達(dá)到高的濃度，但在分散過程中卻因此需要較大分散力。炭黑的分散性能受結(jié)構(gòu)程度的影響，由于高結(jié)構(gòu)炭黑具有良好的分散性能，所以其著色強(qiáng)度也就自然較強(qiáng)。在使用粉狀炭黑時，會出現(xiàn)分散及令人頭疼的灰塵問題，因此，可使用母?；驖{狀物。預(yù)制炭黑的價格要比單純使用顏料黑要高，但若考慮到清潔的工序、高的效率及技術(shù)投資少的優(yōu)點(diǎn)，炭黑制劑是有其價值的。</p><p> 涂料用炭黑重要指標(biāo)二：炭黑著色力著色力（著色強(qiáng)度）是將白色或彩色顏料和炭黑混合時，炭黑的著色能力。也就是炭黑使混合物系光吸收作用提高的程度。這一特性取決于炭黑和顏料的配量比和炭黑本省的性質(zhì)，當(dāng)配量比一定時，某一炭黑的著色能力即為其著色強(qiáng)度，在涂料行業(yè)中稱為著色力。炭黑粒徑小時，結(jié)構(gòu)低，著色力就較高，然而當(dāng)粒子小于20nm時著色能力不再上升，甚至下降。 </p> <p> 涂料用炭黑重要指標(biāo)三：炭黑色相 “炭黑粒子”隨粒徑減小而減弱的光反射還會影響色相。用細(xì)粒徑炭黑進(jìn)行表層黑色著色產(chǎn)生淡藍(lán)色相，它能進(jìn)一步增強(qiáng)高色度視覺印象。用粗粒徑炭黑著色則會產(chǎn)生棕**調(diào)。由于生產(chǎn)工藝的不同，通過不同的工藝條件可得到各種性質(zhì)不同的產(chǎn)品。</p><div

碳黑是碳（主要為石油衍生物）經(jīng)過不完全燃燒形成的精細(xì)粉末狀的準(zhǔn)石墨結(jié)構(gòu)物質(zhì)，表觀呈純黑色粉或者粒狀。產(chǎn)品的著色力，精細(xì)度和密度根據(jù)原料和生產(chǎn)工藝的不同而有很大差異。碳黑不溶于水；有酸堿性之分，燃燒后產(chǎn)生二氧化碳。碳黑的主要成分是碳，同時包含微量氫，氧，硫，灰份，焦油和水份。 </p> <p> 什么是顏料碳黑？ </p> <p> 據(jù)2005年統(tǒng)計數(shù)據(jù)顯示，碳黑的全球年產(chǎn)量接近800萬噸，其中90%以上為橡膠碳黑，用于橡膠補(bǔ)強(qiáng)用途和汽車輪胎；只有大約10%作為色素用于油墨，塑膠和涂料，稱為顏料碳黑，或者色素碳黑。 </p> <p> 顏料碳黑的消費(fèi)量 </p> <p> 顏料碳黑，作為**主要的黑色顏料，是僅次于鈦白粉和氧化鐵的第三大銷量的顏料產(chǎn)品。顏料碳黑的全球年用量（用于著色以及其他特殊用途，區(qū)別于橡膠補(bǔ)強(qiáng)用途）為50萬噸。由此可見，顏料碳黑與橡膠碳黑有著明顯的區(qū)別。 </p> <p> 顏料碳黑的特點(diǎn) </p> <p> 1. 比較好的黑色顏料 </p> <p> 2. 幾乎是低價顏料 </p> <p> 3. 與同類顏料相比有比較好的著色力和遮蓋力 </p> <p> 4. **穩(wěn)定的顏料：有很好的耐熱性，耐化學(xué)性和耐光性。此外還有“槽黑”、“爐黑”。按炭黑性能區(qū)分有“補(bǔ)強(qiáng)炭黑”、“導(dǎo)電炭黑”、“耐磨炭黑”等。上海進(jìn)口碳黑便宜</p><p

年人們在北美地區(qū)***用天然氣為原料生產(chǎn)炭黑，從此炭黑不再是“炱”那么簡單，它是“氣態(tài)或液態(tài)的碳?xì)浠衔镌诳諝獠蛔愕臈l件下進(jìn)行不完全燃燒或熱裂分解所生成的無定形碳，為疏松、質(zhì)輕而極細(xì)的黑色粉末”。大片油氣田相繼開采,源源不斷的原料供應(yīng)推動炭黑生產(chǎn)由手工操作邁入了大規(guī)模工業(yè)化時代。1912 年人們發(fā)現(xiàn)炭黑對橡膠具有補(bǔ)強(qiáng)作用，從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。世界橡膠工業(yè)原材料耗用量排在***位的是生膠，第二位的是炭黑；換言之，炭黑已成為消費(fèi)量比較大的橡膠配合劑。炭黑的耗用量一般占橡膠耗用量的40%～50% ，也就是說，在橡膠配方中，通常每使用2 份橡膠就會搭配使用1 份炭黑。 </p> <p> <br />
