Overview
QCJ-40 Wood Impactor is a special testing instrument designed and manufactured according to GB/T 4893.9-2013 standard. The instrument is mainly used to evaluate the impact resistance of the paint film on the surface of furniture wooden parts.
Features
1. Designed and manufactured according to GB/T 4893.9-2013 standard to meet standard requirements.
2. The height of the catheter is 400mm and the Graduation is 5mm, which is convenient for precise control of the impact height.
3. Impact block weight is 500 +/- 5g, Impact steel ball specification is φ 14-0.01 HRc60~ 66, in line with GB308 standard, to ensure the accuracy and conformity of the test.
4. The working base size is 200 x 250mm, providing a stable test platform.
Principle
The instrument is dropped freely from a specified height along a vertical conduit through a steel cylindrical Impact block. Impact blocks are placed on standard steel balls of specified diameter and Hardness on the surface of the specimen to transmit Impact force to the surface of the specimen. Impact resistance of the paint film is assessed on a numerical scale according to the degree of damage to the surface of the specimen by the paint film at the impact site.
Applications
Assessment of Anti-Impact Capacity of Surface Paint Film on Furniture Wooden Parts
Standards
GB/T4893.9-2013、GB308
Steps
1. Place the instrument on a stable bench.
2. Place the wooden furniture specimen to be tested on the working base.
3. Place the standard steel ball at the predetermined test position on the surface of the specimen.
4. Raise the Impact Block to the required height on the catheter (according to test requirements).
5. Release the Impact block so that it can fall freely along the conduit, the Impact steel ball.
6. Remove the Impact block and steel ball, observe and evaluate the damage degree of the paint film on the surface of the specimen.
7. Rating according to the degree of damage against the standard.
Notice
• Before use, make sure that all parts of the instrument (work base, scale catheter, catheter seat, controller, Impact block, standard steel ball, end cover) are intact and nondestructive.
• Before the test, place the instrument on a stable and sturdy table to ensure that there is no shaking during the test.
• Impact blocks and standard steel balls are key components and need to be handled with care to avoid bumps, and their specifications are regularly checked for compliance.
When releasing the impact block, the operator should ensure that the hand and Miscellaneous parts are kept away from the impact area to prevent injury.
• After the test is completed, the instrument should be cleaned in time and the impact blocks, steel balls and other components should be properly stored.
• Please strictly follow GB/T 4893.9-2013 and other relevant standards for operation and result evaluation.
