油品其实就是石油经过加工后得到的各种产品，咱们日常用的油、柴油、润滑油，还有铺路的沥青都属于这一类。它们主要按用途分为燃料、润滑剂、溶剂和化工原料等几大类。——未知物分析、成分剖析、配方分析、异物分析、工艺开发等服务商罗工13458673265。【差异】不同油品的特性差异挺大的，比如油的密度在0.70~0.77 kg/m3之间，柴油则更高一些，在0.82~0.87 kg/m3。选购时也得看具体用途，像车用油就得根据发动机压缩比来匹配辛烷值（92号、95号或98号）。【用途】油：汽车、摩托车等点燃式发动机的燃料。柴油：卡车、船舶、发电机等压燃式发动机的燃料，也用于部分小型汽车。润滑油：发动机、变速箱、工业机械的润滑。燃料油（重油）：船舶锅炉、工业加热炉、发电厂的燃料。煤油：航空发动机燃料（航空煤油）、灯用燃料、工业溶剂。溶剂油：油漆、橡胶、制药等工业的溶剂或萃取剂。【中科溯源】红外光谱 (IR)：识别官能团和化学键。核磁氢谱 (1H NMR)：分析氢原子结构和环境。气相色谱 (GC) & 液相色谱 (LC)：分离和定量挥发性/非挥发性成分。X射线衍射 (XRD) & X射线荧光光谱 (XRF)：元素分析和晶体结构鉴定。元素分析仪 (如Vario EL Cube)：测C、H、N、S等元素含量，精度高达0.5%。油品成分分析：润滑油、燃料油等配方剖析和污染物化验。PARent; height: 280px;" data-ad-status="filLED">ABSolute;top:0;border:0;width:700px;height:280px;min-height:auto;max-height:none;min-width:auto;max-width:none;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" width="700" height="280" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allow="attribution-reporting; run-ad-auction" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&h=280&adk=4283983259&adf=1507960139&pi=t.aa~a.1182920990~rp.3&w=700&fwrn=3&fwrnh=100&lmt=1769649285&rafmt=1&to=qs&pwprc=5936539123&format=700x280&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&fwr=0&pra=3&rpe=1&resp_fmts=3&aieuf=1&aicrs=1&fa=40&uach=WyJXaW5kb3dzIiwiMTAuMC4wIiwieDg2IiwiIiwiMTMyLjAuNjgwNS4wIixudWxsLDAsbnVsbCwiNjQiLFtbIk5vdCBBKEJyYW5kIiwiOC4wLjAuMCJdLFsiQ2hyb21pdW0iLCIxMzIuMC42ODA1LjAiXSxbIkdvb2dsZSBDaHJvbWUiLCIxMzIuMC42ODA1LjAiXV0sMF0.&abgtt=6&dt=1769649285384&bpp=1&bdt=22&idt=45&shv=r20260127&mjsv=m202601260101&ptt=9&saldr=aa&cookie=ID%3D39311ab799fcb7d5%3AT%3D1768265974%3ART%3D1769648765%3AS%3DALNI_MZqTp4ra4XnzO1BZefXWy-aE5HC3w&gpic=UID%3D000011e382444d9c%3AT%3D1768265974%3ART%3D1769648765%3AS%3DALNI_Mani4pjxjvelYZ6mK4eOVFItllYtA&eo_id_str=ID%3D696fc30ed12722fb%3AT%3D1768265974%3ART%3D1769648765%3AS%3DAA-AfjaEQSzz1tRdpPizySQr3SE-&prev_fmts=0x0&nras=2&correlator=6407283218536&frm=23&ife=1&pv=1&nhd=1&u_tz=480&u_his=7&u_h=720&u_w=1280&u_ah=680&u_aw=1280&u_cd=24&u_sd=1.5&DMC=8&adx=344&ady=305&biw=1263&bih=582&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42532523%2C95378425%2C95381490%2C95381972%2C95379824&oid=2&pvsid=6738541918757097&tmod=1067918076&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&fc=1664&brdim=0%2C0%2C0%2C0%2C1280%2C0%2C1280%2C680%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=132&bc=31&bz=1&ifi=2&uci=2.5y1r3uv5flao&fsb=1&dtd=51" data-google-container-id="2.5y1r3uv5flao" tabindex="0" title="Advertisement" aria-label="Advertisement" data-google-query-id="CPKBp6jJr5IDFXjJFgUdHoQ2Iw" data-load-complete="true"> |
