色素炭黑在塑料應(yīng)用問題色素炭黑基本性能，原生粒徑、結(jié)構(gòu)、孔隙率和表面官能團(tuán)，對塑料性能的影響有以下幾點(diǎn)： </p> <p> 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?yàn)樯靥亢诹Ｗ又g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(shí)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。

涂料用炭黑重要指標(biāo)四：炭黑光澤當(dāng)炭黑粒徑減小或結(jié)構(gòu)提高時(shí)炭黑的吸油量增加，會使涂料的粘度提高，在同樣的炭黑濃度下，涂層表面自由漆料（成膜物質(zhì)）減少，因此光澤降低。當(dāng)表面含氧基團(tuán)或揮發(fā)分增多時(shí)，炭黑在連結(jié)料中的潤濕性提高，粘度降低，涂層表面自由漆料增多，光澤將會提高。 </p> <p> 涂料用炭黑重要指標(biāo)五：炭黑分散性和分散穩(wěn)定性涂料用炭黑聚集體大小一般在20到數(shù)百納米之間，在漆料中不容易分散，炭黑在漆料中的分散下狀態(tài)，對涂料的性能影響很大。還有，炭黑在涂料特別是和其他顏料如鈦白粉等混合使用時(shí)，由于其相對密度、聚集體直徑、形狀和表面化學(xué)性的不同，炭黑容易產(chǎn)生絮凝現(xiàn)象，即影響涂料的分散穩(wěn)定性。這是由于炭黑特別是粒徑小于25nm的炭黑表面存在許多微孔。貴州碳黑導(dǎo)電</p><p style="text-indent:25px">碳黑（carbon black），又名炭黑，是一種無定形碳。貴州碳黑導(dǎo)電</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(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(shí)，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(shí)，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(jià)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(jià)值的。貴州碳黑導(dǎo)電</p><p
