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 </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。上海**碳黑推薦貨源橡膠用炭黑—橡膠用炭黑原來是按粒徑大小來分類的，但后來改為按氮表面積分類。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

</p><p style="text-indent:25px">分散性顏料黑越細(xì)，炭黑聚集體之間接觸點便越多，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，可使用母粒或漿狀物。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，炭黑制劑是有其價值的。藍(lán)光總體散射強(qiáng)烈，在相反方向，即后方的散射也強(qiáng)烈，于是又從著色層中反射出來。</p><div

色素炭黑原生粒徑小(比表面積大) </p> <p> (1)可以提高炭黑的黑度； </p> <p> (2)可以提高炭黑的著色力； </p> <p> (3)可以增強(qiáng)炭黑抗紫外線的能力； </p> <p> (4)可以提高炭黑的電導(dǎo)率； </p> <p> (5)能增大塑料的粘度； </p> <p> (6)降低炭黑的分散性； </p> <p> (7)增加炭黑和塑料的吸水量。 </p> <p> 色素炭黑的分散和穩(wěn)定性如果不能滿足使用的要求，會直接影響塑料制品的性能。常見的問題有：(1)“絮凝”、“返粗”、“團(tuán)聚”是顏料漿中常見的一些分散問題。它們是因為色素炭黑粒子之間的布朗運(yùn)動產(chǎn)生的。要達(dá)到理想的分散，有賴于分散設(shè)備的提高、添加劑的應(yīng)用和另外一些技術(shù)的運(yùn)用。(2)顏料漿分散不好，導(dǎo)致塑料制品的黑度下降，偏棕色，光澤差。這些問題可以通過加大分散力度解決；也可以通過調(diào)整炭黑的填充量來完成；也可以通過增加混合的時間、改善混合條件來解決。(3)塑料粘度高與炭黑添加量過多有關(guān)，而且添加量大，可能會導(dǎo)致塑料過熱。溫度過高會對熱敏性聚合物產(chǎn)生不良反應(yīng)，造成體系過熱，引起凝膠的產(chǎn)生；還會降低色素炭黑的分散質(zhì)量和體系的穩(wěn)定性。因此，減少炭黑的添加量或控制好適當(dāng)?shù)臏囟葧兄跍p少問題的發(fā)生幾率。炭黑越細(xì)，這種效應(yīng)越***。上海**碳黑廠家供應(yīng)</p><p
