Application of Rotational Viscometer in solvent Adhesive viscosity measurement

The Rotational Viscometer is a commonly used instrument in the detection of the viscosity of solvent-based adhesives. Solvent-based adhesives have certain viscosity and fluidity, so their viscosity will directly affect their adhesion and use effect. Rotational viscometers measure the viscosity of solvent-based adhesives to assess their flow and adhesion. By measuring the viscosity of solvent-based adhesives, its formula and process can be adjusted to obtain better adhesion and application effect.

The following is the application and detection steps of the Rotational Viscometer in the viscosity detection of solvent-based adhesives:

1. Prepare solvent-based adhesive samples: Take a certain amount of solvent-based adhesive samples from the production site or packaging, and stir them well.
   

2. Prepare the Rotational Viscometer: According to the properties and testing requirements of the solvent-based adhesive, select a suitable Rotational Viscometer, and install the measuring head and rotor.

3. Preparations before measurement: turn on the power of the viscometer, and adjust the instrument parameters, such as rotation speed, temperature, etc., according to the instrument manual.

4. Start the measurement: Pour the solvent-based adhesive sample into the test cup of the Rotational Viscometer, and use a needle to remove air bubbles to make the surface flat. Slowly put the spindle into the solvent-based adhesive, wait for the solvent-based adhesive to stop fluctuating, and start the Rotational Viscometer to start measuring.

5. Record data: The Rotational Viscometer will automatically record the measurement data, including viscosity value, rotational speed, temperature, etc.

6. Analyzing data: According to the measurement results, analyze the rheological properties, viscosity and other information of the solvent-based adhesive, and carry out quality control and production process optimization of the solvent-based adhesive.

The Rotational Viscometer is a very practical instrument for detecting the viscosity of solvent-based adhesives, which can help manufacturers control the quality and production process of solvent-based adhesives, and improve production efficiency and product quality.
