2004年，我國炭業(yè)伴隨著橡膠工業(yè)前進(jìn)步伐而同步發(fā)展。到2004年底，我國炭業(yè)總年產(chǎn)能力已超過160萬噸，全年炭黑總產(chǎn)量達(dá)125萬噸，比2003年增長23%；進(jìn)口約11.37萬噸，出口約7.85萬噸，表觀消費(fèi)量約128.52萬噸。 </p> <p> 2005年橡膠用炭黑需求增長率將達(dá)16%，需求炭黑約149萬噸，需要進(jìn)口炭黑10萬噸。由于國內(nèi)炭黑企業(yè)都在加大出口量，2005年全國炭黑出口量達(dá)10萬噸，增長速度為17%。這樣，進(jìn)出口將基本持平，國內(nèi)市場炭黑需求量則應(yīng)為實(shí)際出產(chǎn)量。 </p><p>

</p> <p> 涂料用炭黑重要指標(biāo)一：炭黑黑度黑度是涂料用炭黑的主要指標(biāo)，當(dāng)用于黑色涂料的著色時(shí)，例如黑色汽車面漆，要求所用炭黑黑度愈高愈好。當(dāng)將炭黑用于調(diào)色時(shí)，黑素太高添加量太少，反而容易引起不同批次的涂料產(chǎn)品產(chǎn)生色差，故要求使用黑度較低的炭黑。光會(huì)使塑料老化，尤其是陽光中的紫外線會(huì)加速塑料的老化。</p><div

UV油墨用炭黑由于UV油墨的成膜機(jī)理是紫外光與UV油墨中的光引發(fā)劑作用引發(fā)的聚合反應(yīng)，而炭黑對(duì)紫外光有吸收作用，并且粒徑越小，吸收越強(qiáng)，這就造成了UV油墨的固化速度和黑度兩者之間的矛盾。另外，由于UV油墨采用的連接料對(duì)顏料的潤濕性差，在選擇炭黑時(shí)，應(yīng)該優(yōu)先表面極性基團(tuán)豐富的氧化炭黑，以獲得良好的分散效果和儲(chǔ)存穩(wěn)定性。 </p> <p> 單張紙和輪轉(zhuǎn)膠印油墨用炭黑由于膠印印刷墨層是各種印刷方式中**薄的，炭黑在膠印油墨配方中的含量也就比較高，以期獲得滿意的黑度和遮蓋力。當(dāng)承印物為涂布紙時(shí)，印刷廠通常希望獲得較好的黑度和光澤，因此膠印油墨廠通常選用低結(jié)構(gòu)的炭黑以及經(jīng)氧化處理的低結(jié)構(gòu)炭黑作為原料。炭黑越細(xì)，這種效應(yīng)越***。遼寧冶金碳黑</p><p

顏料碳黑原生粒子并非以單獨(dú)地分離狀態(tài)存在。它們通過物理作用形成聚熔體和聚集體。爐黑的聚集程度可以通過工藝的變化來調(diào)整；而氣黑的聚集程度則很難調(diào)控。碳黑原始粒子的聚集程度通常被稱為“結(jié)構(gòu)”。高聚集度的碳黑被稱為高結(jié)構(gòu)碳黑，而低聚集度的碳黑則被稱為低結(jié)構(gòu)碳黑。顏料碳黑所形成的附聚體則呈現(xiàn)出不規(guī)則碎片狀結(jié)構(gòu)。 </p> <p> 碳黑的結(jié)構(gòu)可以用DBP（鄰苯二甲酸二丁酯）吸收值來測量。根據(jù)經(jīng)驗(yàn)，低結(jié)構(gòu)顏料碳黑中，每100g碳黑的DBP吸收值應(yīng)不高于70ml；而高結(jié)構(gòu)顏料碳黑中，每100g碳黑的DBP吸收值應(yīng)不低于110ml。中結(jié)構(gòu)碳黑則居于兩者之間。結(jié)構(gòu)對(duì)顏料碳黑應(yīng)用性有實(shí)質(zhì)性的影響。（吸油值的測量參照ASTM
