How to Maintain the Tips of the Cobb Sizing Tester?

It is the normal tendency of paper and packing material to absorb water from air or the atmosphere. It is therefore essential to know and comprehend the materials used for packaging's water-holding properties or absorbent properties prior to selecting them for use. This will help protect them from being damaged by situations of extreme rain, humidity, and humidity.

UEC's Cobb Sizing Tester and Impact tester are among the top-performing and accurate driven devices that test the water absorption properties of packaging and paper materials. Manufacturers typically use this equipment to create quality packaging materials and offer items in good condition to their customers. When a manufacturer invests in a machine it is their duty to look after and keep it in good working order at all times. In this way, it can reap benefits for a longer amount of time. However, how to achieve this is the main concern.

Let's first find out about the cobb test and then look at what the manufacturers can do to keep the test.

What is The Cobb Sizing Test?

The test of cobb sizing is among the most important tests that professionals employed in the packaging and paper industry are aware of. The test is conducted to determine the resistance to water of the paper as well as the amount of water that is absorbed by its surface. Therefore, by using this test, it is easy to find out if the paper is suitable for high levels of moisture.

The test is conducted under certain conditions for testing and over a specific time frame. Cobb Sizing Tester from UEC includes an integrated couch roller as well as an incline pad that can be used to slide the test sample into test. The sample consists of a handful of papers arranged beneath the pivoting circular. The digital timer that is automated can be used to measure the time of absorption. It automatically starts after the cylinder is pressed down to examine the paper.

Built in stainless steel of the highest quality This machine is light heavy and resistant to corrosion. The standards that apply to this machine are ISO 535, SCAN P12, DIN 53132, TAPPI T 441, EN 20535, and PAPTAC F.2. The tests performed with this device gives fast and accurate results on paper, board and similar materials.

The cob value that is derived from the test is a measure of the absorption capacity of water by the paper. A lower coefficient of cobb means less absorption capacity for the paper, and more durability of the material , even in humid and high humidity.

Maintenance Tips for the Cobb Sizing Testing Equipment?

• Avoid placing any inflammable substance close to the tester.
• The test sample should be placed in a suitable state on the fixture for text.
• In the event of damage to a rubber pad, try replacing it as quickly as possible. This will help prevent leaks.
• Check that the thread of the screw isn't broken. If it is, you can replace it with a new thread so that the clamping process can be done effectively.

Conclusion
Impact tester and Cobb Sizing Tester are two important devices that test capillary rise in particular unsized papers such as blotting paper. We hope you will find this information useful.
