style="text-indent:25px">氣黑的生產(chǎn)工藝氣黑此名稱源于其生產(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)，上海**碳黑合理價(jià)格，根據(jù)不同種類，平均粒徑在10~30nm之間，氣黑平均粒徑為13

分散的目的是使色素炭黑的內(nèi)部結(jié)構(gòu)分布均勻，分散效果直接影響到色素炭黑的特性，還有制品的色相、黑度和遮蓋力等。色素炭黑分散不好會(huì)導(dǎo)致下面的狀況。 </p> <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 />

同時(shí)要注意的是色素碳黑被研磨分散時(shí)，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> 二、紫外線防護(hù)性的應(yīng)用 </p> <p> 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)到完美的紫外線屏蔽作用。 </p> <p> 炭黑對(duì)塑料的紫外線老化的防護(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)。生產(chǎn)：燈黑、氣黑、爐黑和槽黑。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
