沥青在生活中还是比较常见的，但还是有人对它不是非常了解。

　　Asphalt is still quite common in daily life, but there are still people who are not very familiar with it.

　　沥青的主要成分是沥青质、树脂。沥青是一种防水防潮和防腐的有机胶凝材料，包括天然沥青、石油沥青、页岩沥青和煤焦油沥青等四种，一般会用于涂料、塑料、橡胶等工业以及铺筑路面等。

　　The main components of asphalt are asphaltene and resin. Asphalt is an organic binder material that is waterproof, moisture-proof, and corrosion-resistant, including four types: natural asphalt, petroleum asphalt, shale asphalt, and coal tar asphalt. It is generally used in industries such as coatings, plastics, rubber, and road paving.

　　使用时需主要季节变化，如果是冬季的话，需注意低温天气，因为它容易脆裂，如果是夏季的话，就非常容易被软化，但是粘性能被提高。

　　When using, it needs to be mainly affected by seasonal changes. If it is winter, attention should be paid to low temperature weather because it is prone to brittle cracking. If it is summer, it is very easy to soften, but the viscosity can be improved.

　　沥青的主要成分是沥青质、树脂。沥青是由不同分子量的碳氢化合物及其非金属衍生物组成的黑褐色复杂混合物，是高黏度有机液体的一种，多以柏油或焦油的形态存在，表面呈黑色，可溶于二硫化碳。

　　The main components of asphalt are asphaltene and resin. Asphalt is a black brown complex mixture composed of hydrocarbons and their non-metallic derivatives with different molecular weights. It is a type of high viscosity organic liquid that mostly exists in the form of asphalt or tar, with a black surface and is soluble in carbon disulfide.

　　沥青是一种防水防潮和防腐的有机胶凝材料，主要分为煤焦沥青、石油沥青和天然沥青三种，用于涂料、塑料、橡胶等工业以及铺筑路面等。

　　Asphalt is an organic binder material that is waterproof, moisture-proof, and corrosion-resistant. It is mainly divided into three types: coal tar asphalt, petroleum asphalt, and natural asphalt. It is used in industries such as coatings, plastics, rubber, and road paving.

　　沥青改性剂是沥青原料的重要组分,它能够改变沥青的性质和性能,常见的改性剂有沥青淀粉、双酚A和树脂。

　　Asphalt modifier is an important component of asphalt raw materials, which can change the properties and performance of asphalt. Common modifiers include asphalt starch, bisphenol A, and resin.

　　沥青除了主要成分沥青质和树脂以外，其次还有高沸点矿物油和少量的氧、硫和氯的化合物。

　　In addition to the main components of asphaltene and resin, asphalt also contains high boiling mineral oil and small amounts of oxygen, sulfur, and chlorine compounds.

　　沥青具有光泽，一般呈液体、半固体或固体状态，低温时质脆，其粘结性、抗水性和防腐性能均良好。

　　Asphalt has a glossy appearance and is generally in liquid, semi-solid, or solid form. It is brittle at low temperatures and has good adhesion, water resistance, and corrosion resistance.

　　它是一种高黏度有机胶凝材料，呈黑色或是棕黑色胶状，主要有碳氢化合物、非金属衍生物等物质组成。这种材料基本都是以柏油或焦油的形态存在，一般用于铺设路工程上，具有很好的防腐蚀效果。

　　It is a high viscosity organic cementitious material that appears as a black or brownish black gel, mainly composed of hydrocarbons, non-metallic derivatives, and other substances. This material mainly exists in the form of asphalt or tar, and is generally used in road construction projects with good anti-corrosion effect.

　　在土木工程中，沥青是应用广泛的防水材料和防腐材料，主要会应用于屋面、地面、地下结构的防水，木材、钢材的防腐使用。

　　In civil engineering, asphalt is a widely used waterproof and anti-corrosion material, mainly used for waterproofing of roofs, floors, and underground structures, as well as anti-corrosion of wood and steel.

　　成分分析方法

　　Component analysis method

　　样品前处理：根据不同类型样品采取不同科学分离、富集方法（成分做到有机与无机，不同体系组成体系成分的分离）大型仪器分析：定性定量分析，一般采用红外光谱、核磁共振波谱、GC-MS、PY-GC-MS、ICP、IC、HPLC、XPF、GPC等十多种仪器；图谱解析：根据仪器检测出谱图数据，结合行业经验匹配数据库数据佐证：结合图谱解析、结合基础化学常用手段及相关特性验证，多方面验证分析结果；审核：教授及相关行业研发，对分析结果把关审核；后期技术服务：针对客户实际过程中遇到相关问题，工程师给予方案

　　Sample pretreatment: Different scientific separation and enrichment methods are adopted according to different types of samples (organic and inorganic components are separated, and components of different system compositions are separated). Large scale instrument analysis: qualitative and quantitative analysis, generally using more than ten instruments such as infrared spectroscopy, nuclear magnetic resonance spectroscopy, GC-MS, PY-GC-MS, ICP, IC, HPLC, XPF, GPC, etc; Spectrum analysis: Based on instrument detection of spectrum data, combined with industry experience to match database data for verification: combining spectrum analysis, common methods of basic chemistry, and related characteristics verification, verify the analysis results from multiple aspects; Expert review: Professors and related industry R&D experts review and verify the analysis results; Post production technical services: engineers provide solutions to customers' actual problems encountered during the process
