Description

Technical Field

[0001] The utility model relates to the technical field of laboratory testing, in particular to a device for testing the water barrier property of a paper coating. Background Art

[0002] Moisture resistance focuses on testing the water absorption capacity of paper or paperboard. The national standard is GB / T1540-2002 "Determination of water absorption of paper and paperboard - Cobb method". The Cobb method is the most commonly used test method for testing the raw materials that make up cartons. The Cobb method is suitable for testing moisture resistance and water resistance, but not for testing water resistance.

[0003] Applications that require high waterproof performance, such as paper cups, oil-proof paper, lunch boxes, food, and electronic equipment packaging, often require coating to achieve the effect, but this method makes it non-recyclable and causes environmental pollution. By coating the surface of paper, effective recycling can be achieved, which is a more environmentally friendly method. During the product development process, it is necessary to evaluate and test the coated product. The existing test method is still to evaluate through the Cobo method, but the Cobo method can only perform a simple evaluation of the coating.

[0004] The water resistance of the coating, especially the water permeability to evaluate the water barrier effect, cannot be tested. In addition, the kerber method test is greatly affected by the humidity and temperature of the environment, and errors will occur during the weighing and water absorption process, resulting in large deviations in the test data.
