style="text-indent:25px">氣黑的生產(chǎn)工藝氣黑此名稱源于其生產(chǎn)過程：原料烴加熱時先氣化，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，根據(jù)不同種類，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，當溫度仍高時，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，相應氣黑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。上海進口碳黑源頭好貨這是由于炭黑特別是粒徑小于25nm的炭黑表面存在許多微孔。</p><div

《綱要》明確炭黑企業(yè)的行業(yè)準入條件。據(jù)悉，“十二五”期間將不再新建規(guī)模在5萬噸以下的炭黑廠；不再建設產(chǎn)能在2萬噸以下（包括干法造粒和濕法造粒）的炭黑生產(chǎn)裝置。同時，主管部門還將限期淘汰總規(guī)模在5萬噸以下、技術(shù)裝備落后、能耗高、排放超標、作業(yè)環(huán)境不好的炭黑廠；立即淘汰規(guī)模在1.5萬噸以下的干法造粒的生產(chǎn)裝置。 </p> <p> 業(yè)內(nèi)人士指出，之所以將淘汰炭黑行業(yè)的落后產(chǎn)能提上日程，是提高我國橡膠產(chǎn)業(yè)競爭力的迫切需要。 </p> <p> 據(jù)了解，我國目前約有炭黑企業(yè)100家，年產(chǎn)能430余萬噸。但是，行業(yè)內(nèi)中小企業(yè)居多，行業(yè)集中度差，以致科研經(jīng)費投入不足，每年雖然有大量中低端產(chǎn)品出口，但是高性能和特種炭黑產(chǎn)品幾乎全部依賴進口，進而影響到了下游橡膠企業(yè)的發(fā)展。 </p> <p> <br /> </p><p> 涂料用炭黑重要指標四：炭黑光澤當炭黑粒徑減小或結(jié)構(gòu)提高時炭黑的吸油量增加，會使涂料的粘度提高，在同樣的炭黑濃度下，涂層表面自由漆料（成膜物質(zhì)）減少，因此光澤降低。當表面含氧基團或揮發(fā)分增多時，炭黑在連結(jié)料中的潤濕性提高，粘度降低，涂層表面自由漆料增多，光澤將會提高。 </p> <p> 涂料用炭黑重要指標五：炭黑分散性和分散穩(wěn)定性涂料用炭黑聚集體大小一般在20到數(shù)百納米之間，在漆料中不容易分散，炭黑在漆料中的分散下狀態(tài)，對涂料的性能影響很大。還有，炭黑在涂料特別是和其他顏料如鈦白粉等混合使用時，由于其相對密度、聚集體直徑、形狀和表面化學性的不同，炭黑容易產(chǎn)生絮凝現(xiàn)象，即影響涂料的分散穩(wěn)定性。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電性，并用統(tǒng)計方法解釋這個現(xiàn)象。</p><div

</p> <p> 涂料用炭黑重要指標一：炭黑黑度黑度是涂料用炭黑的主要指標，當用于黑色涂料的著色時，例如黑色汽車面漆，要求所用炭黑黑度愈高愈好。當將炭黑用于調(diào)色時，黑素太高添加量太少，反而容易引起不同批次的涂料產(chǎn)品產(chǎn)生色差，故要求使用黑度較低的炭黑。黑度除了受炭黑內(nèi)部的光吸收外，也受粒子表面幾何機構(gòu)的影響而產(chǎn)生了具有增亮效應的光散射，這會降低黑度。上海橡膠碳黑便宜</p><p

<p> 炭黑主要用作橡膠的補強劑和填料，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)良的橡膠補強，塑料著色，導電或抗靜電防紫外線等功能，其應用范圍也在不斷擴大，不同炭黑其應用范圍也不同，小編建議廣大用戶朋友根據(jù)自己需求購買相應的炭黑產(chǎn)品。上海橡膠碳黑便宜</p><p
