顏料自身的性能對涂料有沒有影響？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，黑度值也就相對較低了。這種情況也同樣表現(xiàn)在相對著色力上。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，在潤濕的時(shí)候，也就需要更長的時(shí)間，可以總結(jié)為潤濕性比較差。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，上海***碳黑價(jià)格行情，將其分散到比較好效果，上海***碳黑價(jià)格行情，充分體現(xiàn)出其黑度。要形成穩(wěn)定的分散體系，還要有足夠長的溶劑化鏈段，上海***碳黑價(jià)格行情，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?；蛘哐娱L絮凝返粗產(chǎn)生的時(shí)間。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。上海***碳黑價(jià)格行情</p><div

m的平坦的燃燒鐵盤上燃燒，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。由天然氣制成的稱“氣黑”，由油類制成的稱“燈黑”，由乙炔制成的稱“乙炔黑”。</p><div
