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(xì)，油墨用炭黑黑度和亮度也不能很好的表現(xiàn)出來(lái)。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?yàn)楹诙扰c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(lái)說(shuō)，色素炭黑顏料混入油性樹(shù)脂中，形成基料產(chǎn)品，該產(chǎn)品隨后被制成成品油墨。因?yàn)樘际潜活A(yù)分散于樹(shù)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(rùn)濕。一定的熟化時(shí)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(rùn)濕時(shí)間需要一定的，潤(rùn)濕時(shí)間是因?yàn)樗蕴亢诹Ｗ映叽缧?，一般?5nm(直徑)。是用于水性涂料制造的所有顏料中**細(xì)小的一種。因其尺寸小，形成的顏料團(tuán)會(huì)有相當(dāng)大的表面積，潤(rùn)濕時(shí)間就要比大粒子顏料長(zhǎng)。

style="text-indent:25px">槽黑的生產(chǎn)工藝這種生產(chǎn)工藝以天然氣作原料，槽黑的工藝與氣黑生產(chǎn)工藝的氣體燃燒過(guò)程相似，天然氣燃燒，發(fā)出許多扇形火焰，得到的產(chǎn)品與氣黑類似，而不同的是這里采用了平坦的水冷U形槽作為炭黑的沉積槽。由于生態(tài)和經(jīng)濟(jì)原因，許多年前就停止了這種方法的使用。而氣黑的生產(chǎn)不會(huì)對(duì)生態(tài)環(huán)境造成影響，而此氣法炭藝仍在運(yùn)用。據(jù)記載，中國(guó)是世界上**早生產(chǎn)炭黑的國(guó)家之一。在古時(shí)候，人們焚燒動(dòng)植物油、松樹(shù)枝,收集火煙凝成的黑灰，用來(lái)調(diào)制墨和黑色顏料。這種被稱之為“炱”的黑灰就是**早的炭黑。炭黑由碳組成，但通常被定為無(wú)機(jī)顏料類。</p><div

style="text-indent:25px">色素炭黑這些性能分分鐘影響涂料從標(biāo)題看來(lái)，其實(shí)具體影響涂料的色素炭黑性能，是需要依據(jù)色素炭黑自身的特點(diǎn)慢慢地分析。首先，色素炭黑自身原始粒徑的大小就是一個(gè)主要原因。關(guān)于原始粒徑對(duì)碳黑性能的影響，立升色素炭黑廠家小編就不在一一闡述了。下面進(jìn)入主題討論：在制作黑色涂料時(shí)，色素炭黑的原始粒徑不同還影響其分散性，在體積相同的情況下，原始粒徑較小的色素碳黑，其比表面積較大，由于炭黑之間的空隙較多，在潤(rùn)濕的時(shí)候，也就需要更長(zhǎng)的時(shí)間，可以總結(jié)為潤(rùn)濕性比較差。在分散時(shí)比較好選用性能較好地分散劑以及分散設(shè)備，將其分散到比較好效果，充分體現(xiàn)出其黑度。生產(chǎn)工藝可得到粒徑范圍極廣的炭黑粒子，燈黑生產(chǎn)工藝得到的產(chǎn)品相對(duì)粗糙而氣黑生產(chǎn)工藝可得到精細(xì)的產(chǎn)品。上海正規(guī)碳黑合理價(jià)格</p><p
