style="text-indent:25px">氣黑的生產(chǎn)工藝氣黑此名稱(chēng)源于其生產(chǎn)過(guò)程：原料烴加熱時(shí)先氣化，然后由可自燃的氣體（供以能量）作為載體帶到燃燒器內(nèi)，炭黑在這些蝙蝠形的燃燒器所發(fā)出的大量扇形的火焰中生成。由于每束火焰都較小且在空氣中燃燒，炭黑的形成，與燈黑生產(chǎn)工藝很不同（不完全燃燒）。在此炭黑顆粒很細(xì)，根據(jù)不同種類(lèi)，平均粒徑在10~30nm之間，氣黑平均粒徑為13 nm。燃燒的火焰上，是一個(gè)緩慢旋轉(zhuǎn)的充水轉(zhuǎn)鼓，炭黑在轉(zhuǎn)鼓上沉積，在經(jīng)刮到把炭黑刮走，當(dāng)溫度仍高時(shí)，新生成炭黑與空氣中的氧接觸，于是發(fā)生部分氧化，形成了大量的酸性基團(tuán)，相應(yīng)氣黑pH值介于酸性范圍。并可得到約6%的揮發(fā)份，**其表面氧化物含量。這種被稱(chēng)之為“炱”的黑灰就是**早的炭黑。</p><div

炭黑在塑料工業(yè)中用途之一是防紫外光老化，由于炭黑有較高的吸光性，因而能有效的防止塑料受陽(yáng)光照射而產(chǎn)生光氧化降解。炭黑作為紫外光穩(wěn)定劑在塑料中所起的作用有：把光能轉(zhuǎn)化為熱能；保護(hù)塑料表面而免遭一定波長(zhǎng)的射線(xiàn)照射；截取原子團(tuán)而產(chǎn)生防老化作用，從而阻止催化降解。紫外線(xiàn)對(duì)聚烯烴特別有害，試驗(yàn)證明當(dāng)一定細(xì)度的炭黑的濃度為百分之二時(shí)可以達(dá)到完美的紫外線(xiàn)屏蔽作用。 </p> <p> 炭黑對(duì)塑料的紫外線(xiàn)老化的防護(hù)作用，取決于炭黑的粒徑、結(jié)構(gòu)和表面化學(xué)性。 </p> <p> 炭黑的粒徑較小時(shí)，因表面積增大，其吸收光或遮光能力增加，故紫外線(xiàn)防護(hù)作用增強(qiáng)，但粒徑小于20nm，其防護(hù)作用趨于同一水平，原因是當(dāng)粒徑過(guò)小時(shí)，逆向散射減小，而繼續(xù)向前的光會(huì)威脅聚合物的穩(wěn)定性。 </p> <p> 結(jié)構(gòu)較低，即聚集體尺寸較小時(shí)，因聚集體幾何體積較小，會(huì)增強(qiáng)對(duì)聚合物的防護(hù)作用，這也是結(jié)構(gòu)較低的炭黑較黑的原因。 </p> <p> 炭黑表面含氧基團(tuán)較多，即揮發(fā)份較高時(shí)，能消除聚合物分解時(shí)產(chǎn)生的基因，因此防護(hù)作用也增強(qiáng)。揮發(fā)份含量可判斷表面官能團(tuán)的濃度，也可測(cè)得炭黑的極性。上海進(jìn)口碳黑</p><p

對(duì)炭黑有一定了解的朋友會(huì)問(wèn)，炭黑的分解溫度是多少，炭黑將在什么溫度下開(kāi)始分解，并且在儲(chǔ)存過(guò)程中炭黑會(huì)緩慢分解？本文將為您解決一系列炭黑分解溫度問(wèn)題。具體內(nèi)容如下：炭黑在什么溫度下產(chǎn)生和分解？通常，炭黑在空氣或氧氣中在450°C至500°C之間開(kāi)始分解。炭黑在相同溫度下不會(huì)在氮?dú)庵蟹纸?。炭黑灰測(cè)試通常在550攝氏度下進(jìn)行。儲(chǔ)存期間炭黑會(huì)分解嗎？當(dāng)將炭黑儲(chǔ)存在干燥且密封的環(huán)境中時(shí)，炭黑不易受到分解的影響，并且其保存期限不受限制。但是隨著時(shí)間的流逝，炭黑會(huì)吸收水分，直到達(dá)到平衡值。如果使用炭黑對(duì)保濕很重要，建議將炭黑存放在干燥的環(huán)境中并盡可能密封。研究炭黑分解溫度的方法有哪些？在一般實(shí)驗(yàn)中，熱重分析用于研究炭黑的分解溫度。用熱重（TG）分析法研究炭黑的分解溫度。結(jié)論是，在相同的加熱速率下，炭黑的粒徑越大，外延的炭黑越多。初始分解溫度越高；對(duì)于相同的炭黑，升溫速率越快，炭黑的初始分解溫度越高。黑色外延。在NBR/炭黑化合物中，隨著NBR丙烯腈含量的增加，炭黑外延的初始分解溫度降低，隨著炭黑量的增加，炭黑外延的初始分解溫度升高，而炭黑量后超過(guò)一定值，炭黑外延的初始分解溫度基本穩(wěn)定。在NBR/炭黑/其他配合劑中。上海俄羅斯碳黑源頭直供廠家</p><p
