Various Uses of Cobb Sizing, Stiffness and Bursting Tester

by UniversalEngineering Corporation Universal Engineering Corporation

Cobb sizing tester is utilized for quick assurance of the amount of water consumed by a paper or load up in a given time. A Cobb Sizing Tester measures the measure of fluid infiltration into a sheet of Paper, Cardboard or Corrugated Board.

Water absorptiveness is a component of different qualities of paper or board, for example, porosity, measuring, and so on. The high Cobb estimation of the papers and cardboards demonstrates the capacity of the materials to hold or retain the dampness. Contingent on the utilization of the board, the Cobb esteem should be kept up. The test incorporates analyzing of the amount of water retained in a specific timeframe by non-bibulous paper having a thickness of 0.1 mm.

Universal Engineering Corporation manufactures the best quality of Cobb Sizing Tester as per the standard methods. The standard operating procedure of Universal’s Cob Sizing Tester as per mentioned standards is mentioned below.

· A paperboard or corrugated box is weighted nearest to 0.1 gram.
· Now cork sheet on the metal plate is placed and the weighed specimen is placed on it.
· To ensure the leak-free clamping between the ring and the upper surface of the sample during the test, soft elastic and non-absorbent gasket of same internal dimension as of the ring is used.
· Now water is poured in the fixture as per the requirement of the sample.
· Reject the samples that show any sign of spillage or leakage.
· If any liquid is passed through the sheet to the rubber mat, the test is not acceptable and will be rejected.

Stiffness tester

A Stiffness Tester is used to evaluate stiffness and resiliency properties of materials including paper, plastics, cardboard, light metallic sheets, foil and other flexible material having comparatively strong bending resistance up to 10,000 Taber stiffness units.

Stiffness tester is a bi-directional pendulum measuring framework. Giving an exact and responsive technique for measuring little load augments, this framework is a basic segment for deciding material solidness or strength.

To permit the testing of materials with various solidness properties, range weights can be connected to the pendulum. To a great degree lightweight materials, a compensator goes weight is mounted to the highest point of the pendulum. Range weights of 500, 1000 and 2000 "Taber Units" are mounted to the base of the pendulum and required for stiffer materials.

Bursting tester

A bursting strength tester or a bursting tester is designed to find bursting strength of paper and paperboard.

The tester is fitted with an engine is driven cam system, which expands liquid removal on the lower side of the diaphragm at a specified rate. The hardware is fitted with a course of action, which naturally cuts down the weight and stops the engine on a finish of the test cycle. A greatest perusing sort computerized weight gage gives the blasting weight.

The hardware is shoddily intended to give a long and inconvenience free life. The components are brighter chrome covered or painted with metallic paint to give the analyzer a tasteful appearance.
