style="text-indent:25px">光穩(wěn)定性光會使塑料老化，尤其是陽光中的紫外線會加速塑料的老化。在配合運用有機紫外光吸收劑和抗氧化劑可使壽命延長。然而顏料黑仍然被認(rèn)為是比較好的紫外線穩(wěn)定劑。顏料黑作為紫外光吸收劑，主要用作延長塑料制品在戶外使用壽命。濃度為0.5%的小粒徑炭黑（20 nm）與2%的相對粗粒徑的炭黑（95 nm）差不多具有同樣的光保護作用。食品接觸所有涉及到食品衛(wèi)生法規(guī)定的日用品的著色顏料，包括顏料必須符合規(guī)定的純凈標(biāo)準(zhǔn)。首先，這些標(biāo)準(zhǔn)規(guī)定了一般顏料它的重金屬的含量，其組分在0.1N鹽酸中的溶解度（和胃液的酸度一樣），以及規(guī)定芳香氨的含量。而后，特別制定了關(guān)于炭黑的純凈標(biāo)準(zhǔn)，而這一標(biāo)準(zhǔn)因國家而不同。上海進口碳黑黑度是指炭黑所具有的黑色呈現(xiàn)強度。</p><div

style="text-indent:25px">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?！虾Ａ⑸龑崢I(yè)有限公司</p><p style="text-indent:25px"> 顏色與粒徑的大小、顆粒的表面結(jié)構(gòu)及其所吸附揮發(fā)物的成分、數(shù)量有一定的關(guān)系。色素炭黑的黑度和亮度，常以良好的分散性作為先決條件，否則，就算粒徑細，油墨用炭黑黑度和亮度也不能很好的表現(xiàn)出來。在干燥狀態(tài)下，顏色與分散在色漿中的絲印油墨炭黑顏色是不一致的，因為黑度與它的分散性有很大關(guān)系。顏料油墨炭黑賦予了黑色油墨顏色特征，就水性油墨炭黑分散體或濃縮漿來說，色素炭黑顏料混入油性樹脂中，形成基料產(chǎn)品，該產(chǎn)品隨后被制成成品油墨。因為碳是被預(yù)分散于樹脂中的，這樣它在用于制造油墨及用于印刷工藝之前，就有可能獲得充分的潤濕。一定的熟化時間可使碳粒子被浸濕，并在其后生產(chǎn)較好的印刷用油墨。潤濕時間需要一定的，潤濕時間是因為水性炭黑粒子尺寸小，一般在25nm(直徑)。是用于水性涂料制造的所有顏料中**細小的一種。因其尺寸小，形成的顏料團會有相當(dāng)大的表面積，潤濕時間就要比大粒子顏料長。炭黑是烴類經(jīng)氣相不完全燃燒或熱裂解而成的黑色粉末狀物質(zhì)。</p><div

同時要注意的是色素碳黑被研磨分散時，粒子細度應(yīng)不大于15um。在有些涂料中，甚至要求低于5um。此外還有“槽黑”、“爐黑”。按炭黑性能區(qū)分有“補強炭黑”、“導(dǎo)電炭黑”、“耐磨炭黑”等。上海橡膠碳黑</p><p style="text-indent:25px">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。上海橡膠碳黑</p><p> 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，對塑料性能的影響有以下幾點： </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動產(chǎn)生的。要達到理想的分散，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。上海橡膠碳黑</p><p
