垃圾袋，塑料袋，電纜材料之類產(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，炭黑稱量和配料時出現(xiàn)的微小誤差，均會導(dǎo)致明顯的色差，因此，宜采用粒徑較大，上海正規(guī)碳黑供應(yīng)公司，著色力較差的低色素炭黑，這樣炭黑用量可以稍大，稱量誤差相對小些，并有分散性較好、價格較低的優(yōu)點。對于灰色塑料，采用細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)生藍相灰色。與其它有機顏料相比，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?。黑色染料，用于制造中國墨、油墨、油漆等，也用于做橡膠的補強劑。上海正規(guī)碳黑供應(yīng)公司</p><div

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(dāng)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(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。上海進口碳黑源頭好貨黑度除了受炭黑內(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(yīng)的光散射，這會降低黑度。</p><div

4.5之間，吸附能力越強，普通的絲印油墨炭黑PH值幾乎是中性的，因此其吸附能力不明顯。由于吸附能力對于涂料的干燥性有特殊影響，常因吸附色漆中的催干劑而使涂膜干率減退。PH值為4以下時，酸性越大，對催干劑的吸附能力也越大，則對抗干性能影響也就越明顯。色素炭黑的抗干作用，不是在制漆后立即表現(xiàn)出來，而是在完全或部分地對催干劑吸附后（貯存期內(nèi)），經(jīng)過一段時間才反應(yīng)出來。因此，在設(shè)計色漆配方時，要考慮適當(dāng)增加催干劑用量。 </p><p> 二、紫外線防護性的應(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；保護塑料表面而免遭一定波長的射線照射；截取原子團而產(chǎn)生防老化作用，從而阻止催化降解。紫外線對聚烯烴特別有害，試驗證明當(dāng)一定細度的炭黑的濃度為百分之二時可以達到完美的紫外線屏蔽作用。 </p> <p> 炭黑對塑料的紫外線老化的防護作用，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，因表面積增大，其吸收光或遮光能力增加，故紫外線防護作用增強，但粒徑小于20nm，其防護作用趨于同一水平，原因是當(dāng)粒徑過小時，逆向散射減小，而繼續(xù)向前的光會威脅聚合物的穩(wěn)定性。 </p> <p> 結(jié)構(gòu)較低，即聚集體尺寸較小時，因聚集體幾何體積較小，會增強對聚合物的防護作用，這也是結(jié)構(gòu)較低的炭黑較黑的原因。 </p> <p> 炭黑表面含氧基團較多，即揮發(fā)份較高時，能消除聚合物分解時產(chǎn)生的基因，因此防護作用也增強。由于在觀察的那一面缺少藍光成分，著色層在透射過程中觀察時，便呈現(xiàn)棕**調(diào)。</p><div

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125萬噸，比2003年增長23%；進口約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16%，需求炭黑約149萬噸，需要進口炭黑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10萬噸，增長速度為17%。這樣，進出口將基本持平，國內(nèi)市場炭黑需求量則應(yīng)為實際出產(chǎn)量。 1912 年人們發(fā)現(xiàn)炭黑對橡膠具有補強作用，從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。上海**碳黑銷售公司</p><p style="text-indent:25px">炭黑作著色時，黑度主要基于對光的吸收，對于特定濃度的炭黑，炭黑越細小，則光吸收程度越高。上海正規(guī)碳黑供應(yīng)公司</p><p> 碳黑技術(shù)工藝（生產(chǎn)方法） </p> <p> 全球碳黑生產(chǎn)工藝一般為爐法、接觸法（主要為槽法和無槽氣法）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猝熄火焰來控制。然后，使用過濾系統(tǒng)把產(chǎn)成的顏料碳黑從氣煙中分離出來。爐法的特點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> 而氣法即無槽氣法，是從槽法改進而來的生產(chǎn)工藝。槽法是將固態(tài)烴（粗蒽）或液態(tài)烴（蒽油）經(jīng)氣化釜氣化后，和可燃性氣體（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。無槽氣法即火房不設(shè)槽鋼冷卻面的改進工藝。這種工藝生產(chǎn)出來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)。上海正規(guī)碳黑供應(yīng)公司</p><p
