CA-100A Contact Angle Meter Basic Static Contact Angle Measuring Instrument

CA-100A Contact Angle Meter Basic static contact Angle measuring instrument

Summary:

At the boundary point between the solid and the gas phase where the liquid contacts, the tangent line of the droplet surface is made. The Angle between the liquid and the surface of the solid is called the contact Angle.

Contact Angle meter is mainly used to measure the contact Angle of liquid to solid, namely measuring the penetration of liquid to solid, by measuring the liquid contact Angle to the solid, calculation, determination of liquid free energy or liquid to solid adhesion, tension index, the instrument can be widely used in petroleum, chemical industry, medicine, paper, dye, spraying, printing, dyeing, mineral processing and other fields, for scientific research and teaching.

Apply:

The specific application fields are given as follows:

1. During the metal welding process, test the adhesion of the flux to the metal;

2. Printing industry adhesion between ink, metal and paper;

3. Study on the degree of bonding between adhesive agent and solid;

4. Wetwetting degree of aircraft matrix by air rain and fog in space industry;

5. Determination of the contact Angle of shrapnel in the air and rain and fog in military science;

6. In the process of petroleum exploitation, the determination of the advance and backward Angle of solid in injected additives and crude oil;
