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。

對(duì)炭黑有一定了解的朋友會(huì)問，炭黑的分解溫度是多少，炭黑將在什么溫度下開始分解，并且在儲(chǔ)存過程中炭黑會(huì)緩慢分解？本文將為您解決一系列炭黑分解溫度問題。具體內(nèi)容如下：炭黑在什么溫度下產(chǎn)生和分解？通常，炭黑在空氣或氧氣中在450°C至500°C之間開始分解。炭黑在相同溫度下不會(huì)在氮?dú)庵蟹纸?。炭黑灰測(cè)試通常在550攝氏度下進(jìn)行。儲(chǔ)存期間炭黑會(huì)分解嗎？當(dāng)將炭黑儲(chǔ)存在干燥且密封的環(huán)境中時(shí)，炭黑不易受到分解的影響，并且其保存期限不受限制。但是隨著時(shí)間的流逝，炭黑會(huì)吸收水分，直到達(dá)到平衡值。如果使用炭黑對(duì)保濕很重要，建議將炭黑存放在干燥的環(huán)境中并盡可能密封。研究炭黑分解溫度的方法有哪些？在一般實(shí)驗(yàn)中，熱重分析用于研究炭黑的分解溫度。用熱重（TG）分析法研究炭黑的分解溫度。結(jié)論是，在相同的加熱速率下，炭黑的粒徑越大，外延的炭黑越多。初始分解溫度越高；對(duì)于相同的炭黑，升溫速率越快，炭黑的初始分解溫度越高。黑色外延。在NBR/炭黑化合物中，隨著NBR丙烯腈含量的增加，炭黑外延的初始分解溫度降低，隨著炭黑量的增加，炭黑外延的初始分解溫度升高，而炭黑量后超過一定值，炭黑外延的初始分解溫度基本穩(wěn)定。在NBR/炭黑/其他配合劑中。顏料炭黑的粒子細(xì)度可低至5
