When pyrolyzed below 260°C, all epoxy resins will produce acetaldehyde. The steps are: placing test pods in a pyrolysis tube, covering the filter paper with a freshly prepared 5% nitrocyanide and morpholine in water, and heating in an oil bath to 240°C. When the gas emitted by thermal cracking passes through the filter paper. Blue filter paper indicates epoxy resin.
Epoxy resins can also be identified by the method of dispensing: About 100 milligrams of resin are taken in about 10 milliliters of concentrated sulfuric acid at room temperature, followed by the addition of about 1 milliliter of concentrated nitric acid. Five minutes later, 5% aqueous sodium hydroxide solution was carefully added to the top of the solution. If bisphenol A epoxy resin was present, the cherry red color appeared at the interface between the two layers.
BMI tape measure has several kinds of case shapes-round shape, heart shape, and drip shape. Today we will introduce this round and biggest one for you.
We have Spanish version and other language versions.
To check your waist size, the tape marked with 3 colors zones (green for healthy, orange for over weight, red for over obese)
There are 2 widths for the tapelines: 13mm and 7.5mm
For example, you are 160cm height and weight 55kgs, match them, then check the BMI arrow point to healthy.
