How to measure the ammonia content in the Automotive Wiring Harness Protection Sleeve?

The Automotive Wiring Harness Protection Sleeve is the raw material for the processing and production of latex tube products. If the Automotive Wiring Harness Protection Sleeve wants to ensure the quality of the product, ammonia is generally used for preservation. However, the ammonia content used in different quality Automotive Wiring Harness Protection Sleeve is also different, so how should the ammonia content in the Automotive Wiring Harness Protection Sleeve be measured?

Automotive Wiring Harness Protection Sleeve are generally measured by alkalinity. Different types of Automotive Wiring Harness Protection Sleeve have obvious differences between alkalinity and PH value. The degree refers to the content of free alkali in the Cable Sleeve, usually expressed in mass percent).
Shared by the manufacturer: the alkalinity of the protective sleeve of the automobile wire harness preserved with ammonia is usually indicated by the ammonia content. In the presence of the solvent solution, use sulfuric acid or hydrochloric acid standard titration solution to titrate the diluted Cable Sleeve to a pH value of 6 to determine the alkalinity. If potentiometric titration is not used, 1.0% methyl red solution can also be used as a visual indicator. When the color turns pink, it is the end point.
If you want to measure the pH value of the Cable Sleeve, you can use a pH meter calibrated with borax solution and potassium hydrogen phthalate solution, with a glass electrode and a saturated calomel cell for measurement
