style="text-indent:25px">1）燈黑生產(chǎn)工藝歷史上**早的炭黑生產(chǎn)法是燈黑生產(chǎn)工藝，在該工藝過(guò)程中，原料在直徑大至1.5 m的平坦的燃燒鐵盤(pán)上燃燒，含有炭黑的燃燒氣體由內(nèi)鋪有磚塊的排氣罩收集，然后通過(guò)彎管（彎折1/4）和通火管到達(dá)沉積的裝置。為了控制所產(chǎn)炭黑的特性，應(yīng)當(dāng)保證在燃燒盤(pán)和排氣罩之間的間隙附近，原料主要作不完全燃燒。而在稍進(jìn)管道里面，燃燒在氧氣不足下發(fā)生熱烈解，因而形成較大的炭黑顆粒，由于這些原因，組成較寬范圍的粒徑分布，主要特征為顆粒粗大。由于在燃燒盤(pán)和排氣罩間隙間形成的顆粒只有小部分能與空氣中的氧份接觸，因此這些炭黑只有少量的表面氧化物，相應(yīng)的pH值呈中性，并且揮發(fā)份極少。貴州冶金碳黑此外還有“槽黑”、“爐黑”。按炭黑性能區(qū)分有“補(bǔ)強(qiáng)炭黑”、“導(dǎo)電炭黑”、“耐磨炭黑”等。</p><div

涂料用炭黑重要指標(biāo)二：炭黑著色力著色力（著色強(qiáng)度）是將白色或彩色顏料和炭黑混合時(shí)，炭黑的著色能力。也就是炭黑使混合物系光吸收作用提高的程度。這一特性取決于炭黑和顏料的配量比和炭黑本省的性質(zhì)，當(dāng)配量比一定時(shí)，某一炭黑的著色能力即為其著色強(qiáng)度，在涂料行業(yè)中稱(chēng)為著色力。炭黑粒徑小時(shí)，結(jié)構(gòu)低，著色力就較高，然而當(dāng)粒子小于20nm時(shí)著色能力不再上升，甚至下降。 </p> <p> 涂料用炭黑重要指標(biāo)三：炭黑色相 “炭黑粒子”隨粒徑減小而減弱的光反射還會(huì)影響色相。用細(xì)粒徑炭黑進(jìn)行表層黑色著色產(chǎn)生淡藍(lán)色相，它能進(jìn)一步增強(qiáng)高色度視覺(jué)印象。用粗粒徑炭黑著色則會(huì)產(chǎn)生棕**調(diào)。 </p><p

style="text-indent:25px">黑度黑度是指炭黑所具有的黑色呈現(xiàn)強(qiáng)度。炭黑作著色時(shí)，黑度主要基于對(duì)光的吸收，對(duì)于特定濃度的炭黑，炭黑越細(xì)小，則光吸收程度越高。黑度除了受炭黑內(nèi)部的光吸收外，也受由于粒子表面幾何機(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。隨著粒徑的減小，光散射程度降低。只有對(duì)于很細(xì)的炭黑，提高炭黑的濃度才能提高黑度，對(duì)于粗大的炭黑，具支配因素的光散射程度因炭黑數(shù)增加而提高，黑度反而相應(yīng)降低。著色強(qiáng)度著色強(qiáng)度可以理解為抵消白色顏料增白能力的效果。著色強(qiáng)度也是隨著原生粒子的粒徑減小和結(jié)構(gòu)的減小而提高。1912 年人們發(fā)現(xiàn)炭黑對(duì)橡膠具有補(bǔ)強(qiáng)作用，從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。福建碳黑橡膠</p><p style="text-indent:25px">由于炭黑的表面積較大，容易吸附揮發(fā)份環(huán)境中的水分，所以炭黑在運(yùn)輸貯存及使用過(guò)程中要特別注意吸濕問(wèn)題。福建碳黑橡膠</p><p style="text-indent:25px">炭黑的粒徑顏料炭黑的粒子細(xì)度可低至5 nm，一般說(shuō)來(lái)，炭黑粒子不是孤立存在的，而是多個(gè)粒子通過(guò)碳晶層互相穿插，形成鏈枝狀。不同生產(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。用爐黑生產(chǎn)工藝可得到幾乎所有粒徑范圍的炭黑，同一品種的炭黑，其粒子大小并不完全相同，呈現(xiàn)一個(gè)粒徑分布范圍。一般來(lái)說(shuō)，粒子較細(xì)的品種，粒徑分布較窄。炭黑的生產(chǎn)工藝不同，則表面的化學(xué)性能也有差別。大多數(shù)炭黑的真實(shí)表面積大于由粒徑計(jì)算出的幾何表面積。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。福建碳黑橡膠</p><p
