Overview
This machine is China ZY-BC film pendulum impact instrument, designed and manufactured according to GB8809. It is suitable for measuring the impact toughness of plastic, rubber and other film materials and metal foils. The instrument impacts and breaks through the sample at a certain speed through the semicircular ball punch, and measures the energy consumed by the punch to evaluate the anti-pendulum impact energy of the film sample.
Features
1. Designed and manufactured according to GB8809 standard.
2. It is suitable for impact toughness testing of various materials such as plastics, rubber films and metal foils.
3. Impact performance of the material is evaluated by Basis Weight measurement of the energy consumed by the punch.
4. Equipped with impact heads and specimen clamps of different sizes to adapt to a variety of testing requirements.
Principle
The instrument releases the pendulum by raising the pendulum to a 90-degree angle, causing the semicircular punch to impact and break through the sample fixed on the clip at an Impact speed of 2.5m/s. The system measures and records the energy consumed by the punch during the process of breaking through the sample. The energy value is the anti-pendulum Impact energy of the sample, which is used to evaluate the impact toughness of the material.
Applications
Impact toughness test of Plastic film, Rubber film, Metal foil
Steps
According to the sample requirements, prepare a sample with a size of 100mm x 100mm.
2. According to the sample thickness and test requirements, choose the appropriate impact head size (25.4 mm or 12.7 mm) and sample clamping diameter (50 mm, 60 mm or 89 mm).
3. Hold the specimen evenly on the specimen holder.
4. Adjust the swing angle of the pendulum to 90 ° and fix it.
5. Release the pendulum so that the punch can Impact the specimen at a speed of 2.5 m/s.
6. Read and record the Impact Energy consumption value displayed by the instrument (Graduation 0.025J).
7. Conduct multiple tests and calculate averages to obtain reliable results.
Notice
Before use, make sure that the instrument is placed horizontally and check whether the components are tight.
• When selecting the impact head and clip size, match the material and thickness of the sample.
• The specimen must be flat, wrinkle-free, and completely cover the clamping area for firm clamping.
• Before releasing the pendulum, make sure there is no one in the test area to prevent the pendulum from accidentally injuring people.
• Regularly check the abrasion of pendulum bearings and Impact heads and perform necessary maintenance.
• The maximum impact energy of the instrument is 3J, please do not use it beyond the range.
• Test environment should avoid strong airflow and vibration to ensure Test accuracy.
