style="text-indent:25px">炭黑的結(jié)構(gòu)性是以炭黑粒子間聚成鏈狀或葡萄狀的程度來表示的。由凝聚體的尺寸、形態(tài)和每一凝聚體中的粒子數(shù)量構(gòu)成的凝聚體組成的炭黑稱為高結(jié)構(gòu)炭黑。常用吸油值表示結(jié)構(gòu)性，吸油值越大，炭黑結(jié)構(gòu)性越高，容易形成空間網(wǎng)絡(luò)通道，而且不易破壞。高結(jié)構(gòu)炭黑顆粒細(xì)，網(wǎng)狀鏈堆積緊密，比表面積大，單位質(zhì)量顆粒多，有利于在聚合物中形成鏈?zhǔn)綄?dǎo)電結(jié)構(gòu)，其中在眾多炭黑品種中以乙炔炭黑為比較好。粒徑分布寬的炭黑粒子比分布窄的炭黑粒子更能賦予聚合物導(dǎo)電性，并用統(tǒng)計方法解釋這個現(xiàn)象。粒徑分布寬的炭黑，少數(shù)大直徑粒子需要數(shù)目巨大，直徑更小的粒子給予補償，相同平均粒徑分布寬的炭黑比分布窄的炭黑有更多的粒子總數(shù)。</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，當(dāng)把顏料黑摻入料，即開始進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，所以其著色強度也就自然較強。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。炭黑由碳組成，但通常被定為無機顏料類。</p><div

4.5之間，吸附能力越強，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，酸性越大，對催干劑的吸附能力也越大，則對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催干劑吸附后（貯存期內(nèi)），經(jīng)過一段時間才反應(yīng)出來。因此，在設(shè)計色漆配方時，要考慮適當(dāng)增加催干劑用量。揮發(fā)份含量可判斷表面官能團的濃度，也可測得炭黑的極性。上?？ú┨靥己?/p><p

style="text-indent:25px">紫外線防護性的應(yīng)用炭黑在塑料工業(yè)中用途之一是防紫外光老化，由于炭黑有較高的吸光性，因而能有效的防止塑料受陽光照射而產(chǎn)生光氧化降解。炭黑作為紫外光穩(wěn)定劑在塑料中所起的作用有：把光能轉(zhuǎn)化為熱能；保護塑料表面而免遭一定波長的射線照射；截取原子團而產(chǎn)生防老化作用，從而阻止催化降解。紫外線對聚烯烴特別有害，試驗證明當(dāng)一定細(xì)度的炭黑的濃度為百分之二時可以達到完美的紫外線屏蔽作用。炭黑對塑料的紫外線老化的防護作用，取決于炭黑的粒徑、結(jié)構(gòu)和表面化學(xué)性。炭黑的粒徑較小時，因表面積增大，其吸收光或遮光能力增加，故紫外線防護作用增強，但粒徑小于 20nm，其防護作用趨于同一水平，原因是當(dāng)粒徑過小時，逆向散射減小，而繼續(xù)向前的光會威脅聚合物的穩(wěn)定性。結(jié)構(gòu)較低，即聚集體尺寸較小時，因聚集體幾何體積較小，會增強對聚合物的防護作用，這也是結(jié)構(gòu)較低的炭黑較黑的原因。炭黑表面含氧基團較多，即揮發(fā)份較高時，能消除聚合物分解時產(chǎn)生的基因，因此防護作用也增強。上海導(dǎo)電碳黑詢問報價</p><p
