id="2vsuw7h" class="box"><p><p> 1821 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?xì)浠衔镌诳諝獠蛔愕臈l件下進(jìn)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(xì)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(bǔ)強(qiáng)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，江蘇果立碳黑S470，炭黑已成為消費量比較大的橡膠配合劑，江蘇果立碳黑S470，江蘇果立碳黑S470。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 /> 在爐黑中可檢測到吡喃酮結(jié)構(gòu)，這種結(jié)構(gòu)決定了爐黑的堿性性質(zhì)。江蘇果立碳黑S470</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇果立碳黑S470,碳黑" src="http://tyunfile.71360.com/UpLoadFile/2019/8/8/21/637008955391718328_shhlssy_6193625.jpg"></div><p style="text-indent:25px">色素炭黑是塑料的著色劑、防紫外線老化劑和抗靜電劑。隨著塑料行業(yè)的發(fā)展，炭黑在塑料行業(yè)的用量也越來越大，從普通的日用塑料到***的工程塑料都離不開炭黑。用量雖然不多，但它對塑料性能的影響很大，因此，對塑料用炭黑的性能要求更加嚴(yán)格，不同用途的塑料制品對炭黑性能有不同的要求，為降低塑料的成本，炭黑的用量要求盡可能地高，但是，研磨設(shè)備的性能和類型將對炭黑的分散產(chǎn)生重要的影響。不同的塑料要求不同的分散水平。在許多情況下，塑料性能的不足可以直接歸因于炭黑分散的不足，如電纜外殼和光纖等塑料產(chǎn)品，要求炭黑的分散水平能達(dá)到更高層次。對于性能要求很高的塑料，炭黑的充分分散是非常重要的。如果能提高色素炭黑的分散水平，可以使塑料的顏色、色相、粘度、光澤、穩(wěn)定性以及擠出特性等達(dá)到更好的要求。江蘇果立碳黑S470黑度除了受炭黑內(nèi)部的光吸收外，也受粒子表面幾何機(jī)構(gòu)的影響而產(chǎn)生了具有增亮效應(yīng)的光散射，這會降低黑度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇果立碳黑S470,碳黑"

<p> <br /> </p> <p> <br /> </p> <p> 1、顏色強(qiáng)度不穩(wěn)定，黑度展現(xiàn)力度不夠，并且外觀色澤不好。 </p> <p> <br /> </p> <p> 2、色素炭黑內(nèi)部分布不均勻，出現(xiàn)條紋。 </p> <p> <br /> </p> <p> 3、在生產(chǎn)油墨過程中，色素炭黑分散不好直接會導(dǎo)致后期印刷質(zhì)量差。 </p> <p> <br /> </p> <p> 4、擠出機(jī)的過濾篩網(wǎng)被堵塞，在擠出加工吹朔薄膜時，未破碎的炭黑附聚物引起膜泡撕裂。 </p> <p> <br /> </p> <p> 5、引起單絲和扁絲斷裂，制品機(jī)械強(qiáng)度降低。 </p> <p> <br /> </p> <p> 同時要注意的是色素碳黑被研磨分散時，粒子細(xì)度應(yīng)不大于15um。在有些涂料中，甚至要求低于5um。 </p><p style="text-indent:25px">油漆**炭黑的要求: 油漆涂料對其顏料-炭黑的要求，除顏色以外，還對其著色力，吸油量，水分，水溶性，PH值，相當(dāng)密度，粒子形狀大小，耐溶劑性，耐化學(xué)品性，耐候性，沒有害沒有公害性，分散性等有不同的要求。炭黑在物理方面活性很高，但在化學(xué)方面則是不活性的，因此其耐候性和耐化學(xué)品性好。炭黑的黑度和著色力高，價格穩(wěn)定，因此是油漆涂料工業(yè)不可缺少的黑色顏料，常用于家具，建筑，汽車，鐵路車輛和船舶用涂料中，炭黑除用于黑色涂料外，還做為調(diào)色顏料應(yīng)用于灰色及其他顏色的涂料中。顏料黑越細(xì)，炭黑聚集體之間接觸點便越多。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇果立碳黑S470,碳黑"

style="text-indent:25px">色調(diào)“炭黑粒子”的光散射程度，隨著粒徑的減小而降低，除了影響增光效應(yīng)，也影響色調(diào)，原因如下：當(dāng)可將光穿過一主色為黑色的著色層時，短波的藍(lán)光比長波的紅光的散射效應(yīng)更強(qiáng)烈。炭黑越細(xì)，這種效應(yīng)越***。紅光成分由于散射損失較小，因此進(jìn)入著色層的深度大一些。藍(lán)光總體散射強(qiáng)烈，在相反方向，即后方的散射也強(qiáng)烈，于是又從著色層中反射出來。當(dāng)觀察反射過程時，經(jīng)細(xì)炭黑著色的出現(xiàn)藍(lán)**調(diào)，會給人黑度更高的感覺。如果炭黑粗大，則相應(yīng)地呈現(xiàn)棕**調(diào)。當(dāng)觀察透射過程時，相同的著色層（不完全透明的薄膜）的色調(diào)關(guān)系正好相反，隨著粒徑的減小，散射較強(qiáng)的藍(lán)光穿過著色層的深度較小，即藍(lán)光穿過著色層至另一面成分較少，從另一面穿出來。因此，由于在觀察的那一面缺少藍(lán)光成分，著色層在透射過程中觀察時，便呈現(xiàn)棕**調(diào)。當(dāng)以鈦白粉調(diào)灰（灰**調(diào)）時的情形，與在透射過程中觀察主色的著色狀況相似，光線在含有黑色顏料塑料片中的白顏料中來回散射，越小粒徑的炭黑，會使可見光內(nèi)藍(lán)光的散射越強(qiáng)，因此較多其余的紅光部分便透射過來，呈現(xiàn)出帶黃**調(diào)的灰色，相反地，如著色時用粗粒徑的炭黑，尤其是較為粗大的燈黑，則會得到帶藍(lán)**調(diào)的灰色。黑度是指炭黑所具有的黑色呈現(xiàn)強(qiáng)度。江蘇果立碳黑S470</p><p style="text-indent:25px">據(jù)記載，中國是世界上**早生產(chǎn)炭黑的國家之一。江蘇果立碳黑S470</p><p> 2000年前，具有5萬t 年產(chǎn)能力的炭黑企業(yè)只有1 家；2001年年底，全國共有炭黑生產(chǎn)企業(yè)發(fā)展到111家，總生產(chǎn)達(dá)120萬t。其中，生產(chǎn)能力在5萬t/a以上(包括5萬t/a) 的企業(yè)發(fā)展到6 家；具有5萬t 年產(chǎn)能力的炭黑企業(yè)只有1家。2003 年發(fā)展到9 家、全國新增炭黑產(chǎn)能約3815 萬t，全部來自年產(chǎn)115萬～210萬t 濕法造粒炭黑生產(chǎn)線。 </p> <p> 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)為實際出產(chǎn)量。江蘇果立碳黑S470</p><p
