全球碳黑生產(chǎn)工藝一般為爐法、接觸法（主要為槽法和無(wú)槽氣法）和熱解法。我們正在使用的是**重要也是**常用的生產(chǎn)工藝--爐法和氣法。 </p> <p> 所謂爐法就是在密閉的反應(yīng)爐中，將液烴原料（一般是煤焦油）噴射到燃燒的熱空氣和天然氣中，在高溫下經(jīng)熱氧化而分解，所生成碳黑的性能可以通過(guò)猝熄火焰來(lái)控制。然后，使用過(guò)濾系統(tǒng)把產(chǎn)成的顏料碳黑從氣煙中分離出來(lái)。爐法的特點(diǎn)是原材料的選擇范圍很廣，且生產(chǎn)出的碳黑的性能多種多樣。 </p> <p> 而氣法即無(wú)槽氣法，是從槽法改進(jìn)而來(lái)的生產(chǎn)工藝。槽法是將固態(tài)烴（粗蒽）或液態(tài)烴（蒽油）經(jīng)氣化釜?dú)饣螅涂扇夹詺怏w（一般使用天然氣，也使用焦?fàn)t煤氣或水煤氣）混合后作為原料，由環(huán)形布置的管網(wǎng)送入火房在槽鋼下的火嘴中高溫燃燒并經(jīng)槽鋼冷卻面收集生成碳黑的工藝。無(wú)槽氣法即火房不設(shè)槽鋼冷卻面的改進(jìn)工藝。這種工藝生產(chǎn)出來(lái)的顏料碳黑收率較爐法偏低，但原生粒子粒徑小，在黑度和著色力方面均有更好的表現(xiàn)。上海進(jìn)口碳黑多少錢(qián)顏料黑越細(xì)，炭黑聚集體之間接觸點(diǎn)便越多。</p><div

炭黑，輕、松而極細(xì)的黑色粉末。多指碳單質(zhì)微粒，一般是由于有機(jī)物燃燒不充分，其中的氫元素和氧元素轉(zhuǎn)化為水，而碳元素燃燒不充分，就會(huì)脫離分子，形成炭黑。那么，炭黑這樣一種黑色粉末都有哪些作用呢？ <p> 炭黑主要用作橡膠的補(bǔ)強(qiáng)劑和填料，其消耗量大約為橡膠消耗量的一半，橡膠用炭黑占炭黑總量的94％，其中約60％用于輪胎制造。此外，炭黑也可以做成許多其他制品，如電極、干電池、**、電阻器、化妝品及拋光膏中，也是重要的助劑。用作涂料、油墨和塑料的著色劑以及塑料制品的紫外光屏蔽劑等。 </p> <p> 炭黑具有優(yōu)良的橡膠補(bǔ)強(qiáng)，塑料著色，導(dǎo)電或抗靜電防紫外線(xiàn)等功能，其應(yīng)用范圍也在不斷擴(kuò)大，不同炭黑其應(yīng)用范圍也不同，小編建議廣大用戶(hù)朋友根據(jù)自己需求購(gòu)買(mǎi)相應(yīng)的炭黑產(chǎn)品。 </p><p style="text-indent:25px">著色用炭黑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(dá)到的黑度而定。用極細(xì)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(lèi)產(chǎn) 品只需中等水平黑度，可以用比表面積較低，結(jié)構(gòu)較高的炭黑品種；塑料調(diào)色時(shí)，炭黑稱(chēng)量和配料時(shí)出現(xiàn)的微小誤差，均會(huì)導(dǎo)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(chēng)量誤差相對(duì)小些，并有分散性較好、價(jià)格較低的優(yōu)點(diǎn)。對(duì)于灰色塑料，采用細(xì)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(lán)相灰色。與其它有機(jī)顏料相比，炭黑除分散較困難外，其他性能均較好?？茖W(xué)的炭黑配合量，可提供較好的抗靜電或?qū)щ娦?。粒徑分布寬的炭黑粒子比分布窄的炭黑粒子更能賦予聚合物導(dǎo)電性，并用統(tǒng)計(jì)方法解釋這個(gè)現(xiàn)象。</p><div
