Paper absorbance tester
Introduction:
It is an instrument used to determine the surface water absorption of coated paper and cardboard, including corrugated board. It is designed according to the principle of the international general bur method. The instrument adopts the flip type, the operation is simple, convenient, safe and reliable.
Standards:
ISO 535 Paper and board - Determination of water absorption (Kob method)
GB/T 1540 "Determination of water absorption of paper and board"
Advantages:
Measures Key Water Resistance Property: Quantifies the amount of water absorbed by the material surface, providing a direct measure of its water resistance.
Standard Compliant (Cobb Method): Designed based on the internationally recognized Cobb method, ensuring results are comparable and meet industry standards.
Applicable to Various Board Types: Suitable for testing coated paper, cardboard, and corrugated board.
Simple and Convenient Operation: The flip-type design facilitates ease of use.
Safe and Reliable: Designed for safe handling of water and samples during the test.
Features:
Test vessel or cylinder with a standardized measuring area (100 ± 0.2 cm²) where the water is contained and the sample's surface is exposed.
Clamping mechanism (often a lever or screw type) to firmly secure the paper or board sample against the opening of the test vessel, creating a watertight seal for the defined measuring area.
Flip type design allowing the vessel to be easily inverted for draining the water after the test.
Roller with a specified width (200 ± 0.5 mm) and weight (10 ± 0.5 kg) used to blot excess water from the surface of the sample after the exposure time.
Base or stand to support the test vessel and roller.
Designed to accommodate samples of a certain diameter (125 ± 5 mm recommended for cutting the test specimen).
Durable construction suitable for laboratory use.
Likely includes markings or indicators for the water level in the vessel.
Parameters:
Measuring area (cm²) : 100±0.2
Roll width (mm) : 200±0.5
Roll weight (kg) : 10±0.5
Sample diameter (mm) : 125±5
Instrument size (length * width * height)mm: 270*400*300
Net weight (kg) : 25
