Brightener is a special material added to the surface of plastic products, which can improve the brightness and transparency of the product and make it more beautiful. Measuring the viscosity of brighteners can help manufacturers understand their performance and rheological properties during production and application, which is very important for the manufacture of high-quality bright plastic products. Specifically, measuring the viscosity of a brightener can:
Determine the amount added: The amount of brightener added directly affects the brightness and transparency of the product. By measuring the viscosity of the brightener, the added amount can be determined, so as to manufacture high-quality bright plastic products.
Control production quality: The quality of the brightener has a great influence on the brightness and transparency of the product. Measuring the viscosity of brighteners allows for quality control, improving production quality and consistency.
Optimizing the production process: Measuring the viscosity of brighteners can help manufacturers understand their rheological behavior during production and application, thereby optimizing the production process and improving production efficiency and product quality.
Cost saving: The amount of brightener used has a great influence on the cost. By measuring the viscosity of the brightener, its usage can be controlled and the production cost can be reduced.
Measuring the viscosity of brighteners is very important in the manufacture of high-quality bright plastic products, which can help control production quality, optimize production processes and save costs. Rotational viscometers are also widely used in the detection of brightener viscosity.
The following are the steps for measuring the viscosity of brighteners using a Rotational Viscometer:
Prepare the sample: Pour the sample of the polish to be tested into the measuring cup of the Rotational Viscometer.
Adjust measurement conditions: According to the properties of the brightener and measurement requirements, adjust the measurement conditions of the Rotational Viscometer, such as rotation speed, temperature, etc.
Start Measurement: Start the Rotational Viscometer, let it spin and measure the viscosity of the sample. During the measurement, record the measurement result and the measurement time.
Analytical data: convert the measured data into the corresponding viscosity value, usually the unit used is Pa·s or cP.
Judgment result: Compare the measured viscosity value with the specification requirements of the brightener to judge whether the sample meets the requirements. If it does not meet the requirements, it needs to be adjusted accordingly.
NBCHAO reminds you: different types of brighteners have different viscosity characteristics and measurement requirements, so you need to read the operation manual carefully before measuring, be familiar with the use of the instrument, and make corresponding adjustments according to specific conditions.
In addition, safety issues cannot be ignored when testing the viscosity of brighteners. The samples may cause harm to the human body. It is necessary to wear appropriate protective equipment and maintain good ventilation.
