style="text-indent:25px">據(jù)分析，可在炭黑表面檢測如酚基、醌基、羧基等基團(tuán)，這些酸性基團(tuán)濃度在氣黑和氧化爐黑的表面特別高。在爐黑中可檢測到吡喃酮結(jié)構(gòu)，這種結(jié)構(gòu)決定了爐黑的堿性性質(zhì)。揮發(fā)份含量可判斷表面官能團(tuán)的濃度，也可測得炭黑的極性。另外由于炭黑的表面積較大，容易吸附揮發(fā)份環(huán)境中的水分，所以炭黑在運輸，貯存及使用過程中要特別注意吸濕問題。大部分都是探討導(dǎo)電粒子接觸的幾何學(xué)研究。該理論認(rèn)為，炭黑填充量越大，處于分散狀態(tài)的炭黑粒子或炭黑粒子**體的密度也越大，粒子間的平均距離越小，相互接觸的幾率越高，炭黑粒子或炭黑粒子**體形成的導(dǎo)電通路也越多。不同極性的高聚物與炭黑組成共混體系的極性越大，炭黑臨界體積分?jǐn)?shù)就越大，意味著體系的導(dǎo)電性下降，因為炭黑表面含有很強(qiáng)的極性基團(tuán)，基體極性大，作用增強(qiáng)，這時強(qiáng)度增加，卻妨礙導(dǎo)電粒子自身的凝集，以致導(dǎo)電性差。但是在多組分基體樹脂與炭黑組成的共混體系中，由于不同基體的極性不同，填充炭黑會產(chǎn)生偏析現(xiàn)象，這時導(dǎo)電性能取決于炭黑粒子在偏析相中的濃度和分布狀態(tài)，還取決于偏析相高聚物所占比例。吉林冶金碳黑生產(chǎn)工藝可得到粒徑范圍極廣的炭黑粒子，燈黑生產(chǎn)工藝得到的產(chǎn)品相對粗糙而氣黑生產(chǎn)工藝可得到精細(xì)的產(chǎn)品。</p><div

高結(jié)構(gòu)色素炭黑經(jīng)常會被應(yīng)用在綠色輪胎制造領(lǐng)域，它能夠讓輪胎耐磨性和抗滑性得到保持，而且還可以減小滾動阻力，更加省油安全。當(dāng)然這跟高結(jié)構(gòu)色素炭黑的結(jié)構(gòu)特性是分不開的。 </p> <p> 一般的色素炭黑表面光滑，聚集體分布比較狹窄。但是高結(jié)構(gòu)色素炭黑聚集體外觀是繁雜的支鏈狀，這樣會更加豐富多能。溫度緩慢增大的情況下，高結(jié)構(gòu)色素炭黑表面氧化官能團(tuán)脫落，總酸含量降低，但是結(jié)合膠的含量卻在升高。 </p> <p> 比表面積跟色素炭黑的色散自由能是正比關(guān)系的，通過用溫度和氧化處理的結(jié)果不同，從而得出含氧官能團(tuán)不是吸附橡膠的活性中心。 </p> <p> <br /> </p><p> 對炭黑有一定了解的朋友會問，炭黑的分解溫度是多少，炭黑將在什么溫度下開始分解，并且在儲存過程中炭黑會緩慢分解？本文將為您解決一系列炭黑分解溫度問題。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之間開始分解。炭黑在相同溫度下不會在氮氣中分解。炭黑灰測試通常在550攝氏度下進(jìn)行。儲存期間炭黑會分解嗎？當(dāng)將炭黑儲存在干燥且密封的環(huán)境中時，炭黑不易受到分解的影響，并且其保存期限不受限制。但是隨著時間的流逝，炭黑會吸收水分，直到達(dá)到平衡值。如果使用炭黑對保濕很重要，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？在一般實驗中，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。炭黑按用途不同，通常分為色素用炭黑、橡膠用炭黑、導(dǎo)電碳黑和**碳黑。</p><div

顏料自身的性能對涂料有沒有影響？答案是肯定的！但是主要是色素炭黑的哪些性能在影響涂料呢？這個要依據(jù)碳黑自身的特點慢慢地分析。首先，碳黑自身原始粒徑的大小就是一個主要原因。關(guān)于原始粒徑對碳黑性能的影響，就不在一一贅述。在涂料中，碳黑的原始粒徑的的不同，對涂料的影響主要表現(xiàn)為，原始粒徑越小，黑度值越高，與其相反，碳黑的原始粒徑越大，黑度值也就相對較低了。這種情況也同樣表現(xiàn)在相對著色力上。在制作黑色涂料時，碳黑的原始粒徑不同還影響其分散性，在體積相同的情況下，原始粒徑較小的色素碳黑，其比表面積較大，由于碳黑之間的空隙較多，在潤濕的時候，也就需要更長的時間，可以總結(jié)為潤濕性比較差。在分散時比較好選用性能較好地分散劑以及分散設(shè)備，將其分散到比較好效果，充分體現(xiàn)出其黑度。要形成穩(wěn)定的分散體系，還要有足夠長的溶劑化鏈段，也就是分散劑要有合適的分子量，這樣在涂料儲存過程中，色素炭黑顆粒才不會因為布朗運動產(chǎn)生的碰撞而重新絮凝成大的顆?；蛘哐娱L絮凝返粗產(chǎn)生的時間。大多數(shù)炭黑的真實表面積大于由粒徑計算出的幾何表面積。吉林冶金碳黑</p><p

年人們在北美地區(qū)***用天然氣為原料生產(chǎn)炭黑，從此炭黑不再是“炱”那么簡單，它是“氣態(tài)或液態(tài)的碳?xì)浠衔镌诳諝獠蛔愕臈l件下進(jìn)行不完全燃燒或熱裂分解所生成的無定形碳，為疏松、質(zhì)輕而極細(xì)的黑色粉末”。大片油氣田相繼開采,源源不斷的原料供應(yīng)推動炭黑生產(chǎn)由手工操作邁入了大規(guī)模工業(yè)化時代。1912 年人們發(fā)現(xiàn)炭黑對橡膠具有補(bǔ)強(qiáng)作用，從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。世界橡膠工業(yè)原材料耗用量排在***位的是生膠，第二位的是炭黑；換言之，炭黑已成為消費量比較大的橡膠配合劑。炭黑的耗用量一般占橡膠耗用量的40%～50% ，也就是說，在橡膠配方中，通常每使用2 份橡膠就會搭配使用1 份炭黑。 </p> <p> <br />
