有没有那个标准规范是指导化工装置投料开车时的? 国际电工委员会（IEC.....The International Electrotechnical Commission）对化工装置试车有一套标准，分别是： IEC 62337:2006 Commissioning of Electrical, Instrumentation and Control Systems in the Process Industry-Specific Phases and Milestones 《流程工业中电气、仪表和控制系统的试车—各特定的阶段和节点》 IEC 62381:2006 Automation Systems in the Process Industry Factory Acceptance Test (FAT), Site Acceptance Test (SAT), and Site Integration Test(SIT) 《流程工业中的自动控制系统—工厂验收测试(FAT)、现场验收测试(SAT) 和现场集成测试(SIT) 》 IEC 62382:2006 Electrical and Instrumentation Loop Check 《电气及仪表系统的回路检查》 查看更多
DNS试剂配制3,5-二硝基水杨酸不溶解怎么办?Preparation of DNS (Dinitrosalycyclic Acid) solution Different ingredients used for the preparation of DNS solution are as follows: 1). Distilled water 1416 ml 2). 3.5 Dinitrosalycyclic Acid 10.6 g 3). NaOH 19.5 g The above ingredients were dissolved gently in water bath at 80°C until a clear solution was obtained. Then the following chemicals were added. 4). Rochelle salt (sodium potassium tartrate) 300g 5). Phenol (melted at 60°C) 7.5 ml 6). Sodium meta bisulphate 8.3g After dissolving the above ingredients, the solution was filtered through a large coarse sintered glass filter and stored at room temperature in an amber colored bottle to avoid photo oxidation. 按这个方法配，一定会溶，以前我也是遇到不溶解，后来改用这个方法，屡试不爽查看更多
