Cold fill bituminous mixture is a high-tech road repair materials, made from modified liquid petroleum bitumen and aggregate processing by certain hybrid made. 冷补沥青混合料是一种高科技道路修补材料,由液体改性沥青和集料按一定的加工工艺混合制成。
Thermal Insulating Technology for Liquid Bitumen Tanker 液态沥青运输车保温技术
In the process of bituminization of low level waste liquid, to measure the surface temperature of a moving barrel filled with wate liquid and bitumen is essential. 在弱放废液沥青固化工艺中,需要测量移动着的、装有废液和沥青的金属桶的壁温。
Besides bitumen, a lot of organic fluid inclusions composed of liquid hydrocarbon, solid bitumen and gas are discovered in quartz from basalt copper ores in northeastern Yunnan and western Guizhou, suggesting that the bitumen directly came from crude oil. 在滇黔交界地区的峨眉山玄武岩铜矿中除了发现大量沥青外,还在与沥青共生的石英中发现了由液态烃、固体沥青和气相组成的有机包裹体,表明沥青直接来自石油。
This level admitance meter meets the requirements of ease calibration, high stability and measurement accuracy in areas of liquid gas tank, oxidizing tower of asphaltic bitumen, and desalt tank of petroleum crude,( etc.) 此液位计在液化气罐、沥青氧化塔、原油脱盐罐等场合的应用达到了标定方便、稳定性好、测量精度高的要求。
According to the thermal decomposition temperatures ranting from 80~ 160 ℃ to 200~ 240 ℃, it can be deduced that organic matter has evolved to the over-mature stage, as indicated by the existence of liquid hydrocarbon inclusions and bitumen hydrocarbon fluid inclusions in the dolomite. 由于从80~160℃到200~240℃的热解作用,有机物质已演化到过成热阶段。这一过程可由白云岩中存在液态烃及含沥青烃流体包裹体得到证明。
Higher fragrance contained in the oil thick liquid of catalytic cracking is divided, call in the colloidal structure that can improve the bitumen in the hard bitumen, degree of prolonging to improving bitumen has obvious function. 催化裂化油浆中含有较高的芳香分,调入硬沥青中能改善沥青的胶体结构,对提高沥青的延度有明显的作用。
