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)的碳氫化合物在空氣不足的條件下進行不完全燃燒或熱裂分解所生成的無定形碳，為疏松、質(zhì)輕而極細的黑色粉末”。大片油氣田相繼開采,源源不斷的原料供應推動炭黑生產(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)炭黑對橡膠具有補強作用，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% ，山西碳黑硅酮膠**，山西碳黑硅酮膠**，也就是說，在橡膠配方中，山西碳黑硅酮膠**，通常每使用2 份橡膠就會搭配使用1 份炭黑。 </p> <p> <br /> 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。山西碳黑硅酮膠**</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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。山西碳黑硅酮膠**色素用炭黑—國際上，根據(jù)炭黑的著色能力，通常分為三類。</p><div

高結(jié)構(gòu)色素炭黑經(jīng)常會被應用在綠色輪胎制造領域，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不是吸附橡膠的活性中心。 </p> <p> <br /> </p><p style="text-indent:25px">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。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。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?！虾Ａ⑸龑崢I(yè)有限公司炭黑由碳組成，但通常被定為無機顏料類。</p><div

</p> <p> （2）用色母粒拚色達到所需色澤必須十分慎重，OPP常常會發(fā)生色差和色光的變化。 </p> <p> （3）色母粒和其他添加劑會有反應，使用時要注意。 </p> <p> （4）色母粒的稀釋比的選取應注意。選用高的稀釋比，則生產(chǎn)成本較低，但也要受到加工設備的限制。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)。山西碳黑硅酮膠**</p><p style="text-indent:25px">常用吸油值表示結(jié)構(gòu)性，吸油值越大，炭黑結(jié)構(gòu)性越高，容易形成空間網(wǎng)絡通道，而且不易破壞。山西碳黑硅酮膠**</p><p> 2000年前，具有5萬t 年產(chǎn)能力的炭黑企業(yè)只有1 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為實際出產(chǎn)量。山西碳黑硅酮膠**</p><p
