Overview
PUSHEN PS 2931/1 rounded corners with holes is a test grade tinplate designed for industrial coatings performance testing. The product meets the GB2520 standard, the tin plating amount is E4, the Hardness grade is T52, the thickness is 0.28mm, and the surface preparation is carried out according to the requirements of GB9271 to ensure the accuracy and Reliability of the test results.
Features
1. Specially designed for coating performance testing, suitable for adhesion, Hardness, Impact, flexibility, bending, drying time and other tests.
2. Standard tin plating amount (E4) and Hardness grade (T52) are used, and the thickness is uniformly 0.28mm to ensure the conformity of the test substrate.
3. The surface preparation strictly follows the GB9271 standard to reduce the interference of surface factors on the film test results.
4. Provide rounded corners with holes for easy operation and fixation.
5. Standard Encasement is 100 tablets/pack, which is convenient for laboratory batch use.
Principle
As a standardized test substrate, its uniform tin plating, specific Hardness and flat surface provide a stable and consistent carrier for coating. In coating performance testing, the preparation of the coating to be tested on the tinplate can eliminate the influence of substrate differences on adhesion, Hardness, flexibility and other test results, so as to accurately evaluate the performance of the coating itself.
Applications
Industrial coatings performance testing
Standards
GB/T 9271、GB2520
Steps
According to the requirements of the test standard (e.g. GB/T 9271), the surface of the iron plate should be cleaned or pretreated as necessary.
2. The coating to be tested is evenly prepared on the surface of the tinplate according to the specified coating method (such as brushing, lame plating, scraping, etc.).
3. Carry out drying or curing according to the conditions specified in the coating product standard.
4. After drying, the film is tested and evaluated according to the corresponding test method standards (such as adhesion, Hardness, Impact, etc.).
Notice
Before use, please check whether the surface of the iron plate is clean, flat, free of oil or obvious defects.
* The surface preparation steps should be carried out in strict accordance with GB/T 9271 or relevant testing standards to ensure the accuracy of the test results.
* Pay attention to distinguish the size specifications of different models (such as PS 2931/1 120mm * 25mm), and choose the appropriate plate according to the test requirements.
* Keep drying when storing to prevent surface oxidation or contamination.
* For special Dimensions needs, it is recommended to contact the supplier customer service for customized consultation.
