对欧盟填充油中多环芳烃(PAHs)含量测试新标准EN 16143:2013进行解读,并与标准IP 346:1998进行对比。EN 16143:2013测试方法为:通过双液相清洗填充油,使其复杂基质得到净化,利用气相色谱/质谱联用仪对填充油中的苯并(a)芘含量及8种PAHs总含量进行直接测试。与IP 346:1998测试方法相比,EN 16143:2013测试方法的谱峰分离效果好,测试结果更准确。EN 16143:2013已经开始实施,将取代IP 346:1998。 相似文献

正高芳烃油(HA油)最初广泛用于轮胎胶料,因为它们与天然橡胶以及合成橡胶具有良好的相容性。高芳烃油也称为蒸馏芳烃萃取物(DAE),其含有较高浓度的多环芳烃(PAH)。PAH是有机化合物,有两个或多个芳香环,其中有8类被列为致癌物。按照欧洲法规,从2010年1月起,如果填充油含有超过1mg/kg(质量分数为0.0001%)的苯并(a)芘以及所列PAH的总量超过10mg/kg(质量分数0.001%),则不能投放市场或用于生产轮胎。如果在二甲基亚砜DMSO萃取(IP346试验方法)试验中的多环芳烃萃取物 相似文献

<正>3月3日,欧盟委员会发布了法规(EU)No 2015/326,修订RAECH法规(EC)No1907/2006附录XVII中有关多环芳香烃(PAHs)的要求。该法规将于2015年3月23日生效。该法规替换了测试用于生产轮胎或轮胎组件的填充油中的PAHs含量的方法,并规定了18个月的过渡期。在过渡期间,新、旧测试方法都可用来测试相关的限值。 相似文献

Thermal and catalytic coprocessing of waste tires and coal was performed using waste tires from two sources and coals of three different ranks. Bituminous coals yielded higher conversions than either subbituminous coal or lignite when coprocessed with waste tire. In this study waste tires from tire buffing processes were used. One of these materials provided by Rouse Rubber represented the typical composition of most automotive tires while the other material supplied by Uniroyal contained a substantial amount of mineral fillers because the material obtained from buffing the white lettering on the sidewall of the tire. Each of these waste tires when used as a solvent in coprocessing had different solvent qualities; the Rouse waste tire was typically a much better solvent for coal than Uniroyal waste tire. Catalytic coprocessing of waste tires with coal using slurry phase hydrogenation catalysts increased total and coal conversions compared to thermal reactions. Addition of carbon black to the coprocessing system had minimal effect on the conversion or product distributions, while the addition of the heat-treated residue from the liquefied waste tires resulted in enhanced conversion and hexane solubles production from coprocessing systems. The mineral-rich Uniroyal residue was more active than the carbon black-rich Rouse residue. Combining the residues with slurry phase hydrogenation catalysts enhanced their activity even further. 相似文献

目前,轮胎技术发展重点关注两方面问题.一是REACH法规.二是轮胎用新标识。受国际大环境的影响.低能耗、低污染、低排放影响着企业的发展,也促使行业技术不断进步,越来越严格的实施细则和规范无一不促使轮胎工业向着更环保、节能、安全方向发展,由此对合成橡胶的发展和需求也产生了重要影响。 相似文献

Not only technology, but domestic and international economic considerations, social developments, consumer lifestyles, and political pressures are the determinants of tomorrow's tire market. Tires for global markets are subject to international competition and world tire standards. Over-the-road highway tires—auto and truck—need improved technology to meet government safety regulations at affordable user costs. Grading and labeling implies substantial pressure on constructions and fibers. Vehicle design changes to meet demands of changing lifestyles bring other implications for tire and fiber markets. Cost per ton of freight hauled is becoming increasingly important. Earthmover tires of the future will be required to haul greater loads at higher speeds, meaning much larger vehicles, bigger tires, and higher ton miles per hour of payload. 相似文献
