Overview
JW104 paper circular Basis Weight Sampler, also known as Grammage, is suitable for various paper Basis Weight determination and the sampling of standard samples required for the physical performance of sheet burst resistance experiments.
Features
1. The sampling area is 100cm ², and the sample diameter is 112.8mm, which meets the standard requirements
2. sampling error +/- 0.35cm ², Measurement accuracy +/- 0.01mm to ensure sampling accuracy
3. sampling thickness range 0.1~ 1.2mm, Measurement range 0.05~ 1mm, suitable for a variety of paper types
4. Dimension 250 * 270 * 420mm, mass about 23kg, stable and durable structure
Principle
The paper placed in the center of the chassis is circular cut by pressing the pressing rod to drive the upper punching knife to complete the sampling of the standard sample, and the sample slides out from the side through the chute.
Applications
Paper Basis Weight determination, sheet burst resistance experiment Physical performance Standard sample sampling
Standards
QB/T 1671-98 "General technical conditions for punching specimen apparatus for physical performance test of paper and Cardboard"
Steps
1. Place the instrument in the right position on a stable and firm workbench
2. Put the paper flat in the center of the chassis, press the support beam with the left hand to prevent tilting, slowly press the pressure rod to complete the sampling, and the sample slides out from the side of the chute
3. Slowly release the pressure rod, restore the starting position of the upper punch knife, and take out the sample for testing
Notice
• When operating, place the instrument on a stable and firm workbench
• When sampling, the left hand should hold the support beam to prevent the Sampler from tilting forward
• Press the lever action should be carried out slowly
• Slow operation is required when releasing the pressure rod
