GB/T 2793-1995 Focused Adhesive non-volatile-matter content determination. Applicable to all kinds of Adhesive products, the purpose is to accurately determine the proportion of non-volatile substances in Adhesive. The standard clarifies the determination principle of oven heating evaporation solvent, and clarifies the required equipment, such as thermostatic oven, analytical balance. Detailed specification of sample preparation, covering Adhesive weighing and container selection. Specify the heating temperature, duration and other test steps, and the method of calculating non-volatile-matter content based on the mass difference before and after. The standard provides a unified and reliable means for evaluating the active ingredient content of Adhesive, and helps Adhesive mass control and Product Research & Development.
