style="text-indent:25px">紫外線防護(hù)性的應(yīng)用炭黑在塑料工業(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。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。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。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。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)，上海**碳黑銷售電話。炭黑作著色時(shí)，黑度主要基于對(duì)光的吸收，上海**碳黑銷售電話，對(duì)于特定濃度的炭黑，上海**碳黑銷售電話，炭黑越細(xì)小，則光吸收程度越高。上海**碳黑銷售電話</p><div
