Maintenance Tips For Your Cobb Sizing Tester

It is the general tendency of a paper and packaging material to absorb moisture from the air or atmosphere. Therefore, it is important to learn and understand the packaging materials' water holding or absorbing properties before choosing them for use. This will protect them from getting damaged in conditions of heavy humidity, rain, and moisture.

UECIN’s Cobb sizing tester is among the high performance and accuracy driven equipment, that tests the water absorption characteristics of the paper and packaging materials. Manufacturers often source this equipment to make high-quality packaging materials and provide products in the right condition to the customers. However, whenever a manufacturer invests in a machine, it becomes his responsibility to take care of and maintain it at all costs. This way it will reap results for a longer period of time. But how to do it, is a major question.

So let us first learn about the cobb sizing test and then see what manufacturers should do to maintain it.

What Is the Cobb Sizing Test?

The cobb sizing test is one of the most significant tests that people working in the paper and packaging industry are well aware of. It is performed to test the water resistance of the paper and also the amount of water absorbed by its surface. Hence, using this test, we can easily determine if the paper is suitable for high moisture levels.

The test is performed under specific testing conditions and in a certain time period. The cobb sizing tester by UECIN comes with a built-in couch roller and a sliding pad where the sample is placed for the test. This sample consists of a few papers together placed under the pivoting cylinder. The automatic digital timer is used to record the absorption time. It starts automatically as soon as the cylinder is held down to test the papers.

Developed in high-grade stainless steel, this machine is light weighted and corrosion-resistant. The applicable standards of this machine include ISO 535, SCAN P12, DIN 53132, TAPPI T 441, EN 20535, and PAPTAC F.2. The test performed using this tester gives speedy and the most accurate results on paper, paperboard, and materials like these.

The resultant cob value of the test determines the water absorption ability of the paper. A lower cobb value means low absorption capacity of the paper and more stability of the material even during high humidity and moisture.

Maintenance Tips For The Cobb Sizing Testing Equipment?

• Do not place inflammable material in proximity to the tester.

• Place the testing sample in a proper condition on the text fixture.

• In case of a damaged rubber pad, prefer changing it as soon as possible. This will prevent leakages.

• Make sure the thread of the screw is not broken. If it is, replace it with the new thread, so that the clamping can be effectively done.
