id="fzrtv28" class="box"><p><p style="text-indent:25px">碳黑（carbon black），又名炭黑，云南碳黑色素，是一種無定形碳。輕、松而極細的黑色粉末，表面積非常大，范圍從10~3000m2/g，是含碳物質(zhì)（煤、天然氣、重油、燃料油等）在空氣不足的條件下經(jīng)不完全燃燒或受熱分解而得的產(chǎn)物。比重1.8-2.1。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”。此外還有“槽黑”、“爐黑”。按炭黑性能區(qū)分有“補強炭黑”，云南碳黑色素、“導電炭黑”、“耐磨炭黑”等?？勺骱谏玖?，用于制造中國墨、油墨、油漆等，也用于做橡膠的補強劑。炭黑作著色時，黑度主要基于對光的吸收，對于特定濃度的炭黑，云南碳黑色素，炭黑越細小，則光吸收程度越高。云南碳黑色素</p><div

可用BET（Brunauer-Enmet-Teller）即低溫氮吸附方法測定。也可用世界上通用的簡捷的碘吸附方法。測定結(jié)果每克具有的表面積（㎡/g）。 </p> <p> <br /> </p> <p> 粒徑 </p> <p> 炭黑的原聲粒徑，它是通過電子顯微鏡測試的，是一定顆數(shù)粒徑的平均值 </p> <p> <br /> </p> <p> 結(jié)構 </p> <p> 色素炭黑結(jié)構是色素炭黑微粒子聚集體形成的鏈枝程度的表征值，它表示了色素炭黑內(nèi)部的空隙程度。通常以吸油值（DBP吸收值）表示。 </p> <p> <br /> </p> <p> 黑度（反射率） </p> <p> 色素炭黑黑度通常以“反射率測定儀”測定的數(shù)據(jù)來表示，在大部分情況下也反映了該色素炭黑的原始粒徑，是衡量該色素炭場價格的重要參數(shù)之一。反射率越低，色素炭黑黑度越高，粒徑也越小。反之亦然。 </p> <p> <br /> </p> <p> 著色力 </p> <p> 是表示色素炭黑染色白體的能力，一般著色力高，其遮蓋性能好、測試方法按ASTM-3265進行。云南碳黑色素橡膠用炭黑—橡膠用炭黑原來是按粒徑大小來分類的，但后來改為按氮表面積分類。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

色素炭黑一般都能較好的給塑料著色，可根據(jù)著色特性或物化性能選用色素炭黑，著色用炭黑的品種的選擇基本上都是隨成品必須達到的黑度而定。用極細的色素炭黑可以完成黑度要求特別高的著色； PE垃圾袋，塑料袋，電纜材料之類產(chǎn)品只需中等水平黑度，可以用比表面積較低，結(jié)構較高的炭黑品種；塑料調(diào)色時，炭黑稱量和配料時出現(xiàn)的微小誤差，均會導致明顯的色差，因此，宜采用粒徑較大，著色力較差的低色素炭黑，這樣炭黑用量可以稍大，稱量誤差相對小些，并有分散性較好、價格較低的優(yōu)點。 </p> <p> 對于灰色塑料，采用細粒色素炭黑往往呈現(xiàn)棕相灰色，而采用粗粒子色素炭黑可產(chǎn)生藍相灰色。 </p><p style="text-indent:25px">爐黑生產(chǎn)工藝氣黑是在開放大氣中生產(chǎn)的，但爐黑生產(chǎn)工藝則是在缺氧條件下的密閉爐中進行的。使用的不是許多束小火，而是一團大火焰，以油類作原料，并加入可燃氣體使之達到爐內(nèi)所需溫度。而改變爐黑生產(chǎn)工藝條件，可得到所需要之顏料黑。比如：不同條件下，炭黑可達到廣闊的平均粒徑范圍，從80 nm到小至15 nm，更直到細小至氣黑那樣小的顆粒。但對于同一粒徑，氣黑和爐黑還是有區(qū)別的，主要是表面化學不同。爐黑產(chǎn)品較為粗糙，平均粒徑為40nm。此外，當采用爐黑生產(chǎn)工藝時，可加入少量的堿性化合物或其它添加劑以改變聚集體的聚集度和類型，由此可得到高結(jié)構或低結(jié)構的炭黑。由于爐黑是在幾乎低于大氣壓及空氣不足條件下生產(chǎn)出來的。所以它們大部分缺乏酸性表面氧化物，然而卻發(fā)現(xiàn)了前面所提到的呈堿性反應的吡喃酮結(jié)構。關于爐黑的堿性pH值，是因為在終止炭黑生成時噴射淬化冷水中加入堿土，以及為降低結(jié)構而添加的堿性鹽。另外，如果此爐黑不再進行氧化后處理，則其揮發(fā)份含量較低。粒徑分布寬的炭黑，少數(shù)大直徑粒子需要數(shù)目巨大，直徑更小的粒子給予補償。</p><div

style="text-indent:25px">槽黑的生產(chǎn)工藝這種生產(chǎn)工藝以天然氣作原料，槽黑的工藝與氣黑生產(chǎn)工藝的氣體燃燒過程相似，天然氣燃燒，發(fā)出許多扇形火焰，得到的產(chǎn)品與氣黑類似，而不同的是這里采用了平坦的水冷U形槽作為炭黑的沉積槽。由于生態(tài)和經(jīng)濟原因，許多年前就停止了這種方法的使用。而氣黑的生產(chǎn)不會對生態(tài)環(huán)境造成影響，而此氣法炭藝仍在運用。據(jù)記載，中國是世界上**早生產(chǎn)炭黑的國家之一。在古時候，人們焚燒動植物油、松樹枝,收集火煙凝成的黑灰，用來調(diào)制墨和黑色顏料。這種被稱之為“炱”的黑灰就是**早的炭黑。顏料黑作為紫外光吸收劑，主要用作延長塑料制品在戶外使用壽命。云南碳黑色素</p><p

style="text-indent:25px">導電炭黑的隧道效應是什么決定的？不清楚大家是否有關注，**近用電子顯微鏡觀察拉伸狀態(tài)的橡膠不存在炭黑鏈鎖，卻仍有導電現(xiàn)象，立升導電炭黑廠家認可這就是隧道效應。其主要論點認為，導電性是由導電炭黑粒子的隧道決定的。同時并有試驗證明，隨著導電炭黑粒子間距的增大，體積電阻亦隨之升高。還有電場放射導電機理，是因為在研究導電炭黑填充的高分子材料的電壓，電流特性時，發(fā)現(xiàn)其結(jié)果不符合歐姆定律，認為其所以如此，是由于炭黑粒子間產(chǎn)生高的電場強度而發(fā)生電流導致電場放射。綜上所述，無論從哪種導電機理來理解，都認為導電炭黑的種類和配合量是支配材料**終所表現(xiàn)的導電性的主要因素。云南碳黑色素</p><p
