style="text-indent:25px">色素炭黑哪些特點(diǎn)會(huì)影響涂料生產(chǎn) 顏料自身的性能對(duì)涂料有沒有影響？答案是肯定的！但是主要是色素炭黑的哪些性能在影響涂料呢？這個(gè)要依據(jù)碳黑自身的特點(diǎn)慢慢地分析。首先，碳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，就不在一一贅述。在涂料中，碳黑的原始粒徑的的不同，對(duì)涂料的影響主要表現(xiàn)為，原始粒徑越小，黑度值越高，與其相反，碳黑的原始粒徑越大，黑度值也就相對(duì)較低了。這種情況也同樣表現(xiàn)在相對(duì)著色力上。在制作黑色涂料時(shí)，碳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，由于碳黑之間的空隙較多，上?？ú┨靥己谠搭^好貨，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。要形成穩(wěn)定的分散體系，還要有足夠長(zhǎng)的溶劑化鏈段，也就是分散劑要有合適的分子量，這樣在涂料儲(chǔ)存過程中，色素炭黑顆粒才不會(huì)因?yàn)椴祭蔬\(yùn)動(dòng)產(chǎn)生的碰撞而重新絮凝成大的顆粒或者延長(zhǎng)絮凝返粗產(chǎn)生的時(shí)間。在古時(shí)候，人們焚燒動(dòng)植物油，上?？ú┨靥己谠搭^好貨、松樹枝，上?？ú┨靥己谠搭^好貨,收集火煙凝成的黑灰，用來調(diào)制墨和黑色顏料。上?？ú┨靥己谠搭^好貨</p><div

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(huì)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(rùn)濕性提高，粘度降低，涂層表面自由漆料增多，光澤將會(huì)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(duì)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(duì)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。上海進(jìn)口碳黑貨源充足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><div

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(duì)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(huì)出現(xiàn)分散及令人頭疼的灰塵問題，因此，可使用母?；驖{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。</p><p> 什么是碳黑? </p> <p> 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(shí)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(jì)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(diǎn) </p> <p> 1. 比較好的黑色顏料 </p> <p> 2. 幾乎是低價(jià)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。黑度除了受炭黑內(nèi)部的光吸收外，也受粒子表面幾何機(jī)構(gòu)的影響而產(chǎn)生了具有增亮效應(yīng)的光散射，這會(huì)降低黑度。</p><div style="width:100%;text-align:
