JGW-360DContact angle measuring instrument

1Instrument Introduction

Contact angle measuring instrumentThis instrument is used to measure the wettability of liquids to solids. By measuring the contact angle of liquids to solids, calculating and measuring the free energy of liquids, i.e. the adhesion and tension of liquids to solids, this instrument can be widely used in fields such as petroleum, chemical, pharmaceutical, papermaking, dyes, etc. for scientific research and teaching purposes. Our factory producesContact angle measuring instrumentSeries of products, independently developed, providing different models of instruments according to the different needs of users.

2Examples of specific application areas:

1）During the metal welding process, check the adhesion of the flux to the metal;

2）The adhesion between ink, metal, and paper in the printing industry;

3）Study on the degree of adhesion between adhesive and solid;

4）Testing the wetting degree of aircraft substrates by airborne rain and fog in the aerospace industry;

5）Measurement of the contact angle between shrapnel in air and rain and fog in military science;

6）Measurement of the advance and retreat angles of solid additives injected into crude oil during the process of oil extraction;
