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粉末狀的準石墨結(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，用于橡膠補強用途和汽車輪胎；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，上海卡博特碳黑報價，區(qū)別于橡膠補強用途）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 </p> <p> 1，上海卡博特碳黑報價. 比較好的黑色顏料 </p> <p> 2，上海卡博特碳黑報價. 幾乎是低價顏料 </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。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

年人們在北美地區(qū)***用天然氣為原料生產(chǎn)炭黑，從此炭黑不再是“炱”那么簡單，它是“氣態(tài)或液態(tài)的碳氫化合物在空氣不足的條件下進行不完全燃燒或熱裂分解所生成的無定形碳，為疏松、質(zhì)輕而極細的黑色粉末”。大片油氣田相繼開采,源源不斷的原料供應(yīng)推動炭黑生產(chǎn)由手工操作邁入了大規(guī)模工業(yè)化時代。1912 年人們發(fā)現(xiàn)炭黑對橡膠具有補強作用，從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。世界橡膠工業(yè)原材料耗用量排在***位的是生膠，第二位的是炭黑；換言之，炭黑已成為消費量比較大的橡膠配合劑。炭黑的耗用量一般占橡膠耗用量的40%～50% ，也就是說，在橡膠配方中，通常每使用2 份橡膠就會搭配使用1 份炭黑。 </p> <p> <br /> </p><div
