Overview
The WHS-05 heat sealing tester adopts hot-pressing sealing method to determine the heat sealing temperature, heat sealing time, heat sealing pressure and other parameters of Plastic film substrate, Soft Encasement composite film, Spreader paper and other heat sealing composite films, providing accurate heat sealing test indicators. Control system full digitalization, key components adopt familiar brand products, Degree of automation is high, easy to operate.
Features
1. Control system digitalization display, fully automated operation;
2. Digital P.I.D. temperature control, high temperature control accuracy;
3. The heat sealing knife material is made of aluminum alloy, and the temperature conduction is fast and the heat sealing surface temperature is uniform;
4. Customized special mold heating tube, which heats up quickly and has a long lifespan.
5, double cylinder structure, internal adjustable pressure equilibrating mechanism, to ensure that the sealing knife up and down movement left and right consistent;
6, pneumatic control components high accuracy, the full set of familiar brands;
7. Anti-scalding design and leakage protection design make operation safer.
8. The heating elements are carefully designed to ensure a long service life of the equipment.
9. Automatic and Manual Operating Modes for Effective Operation;
10. The operation panel is specially optimized according to ergonomic principles, making it easy to operate.
11. The instrument is equipped with cooling fans on both sides, allowing for uniform and fast heat dissipation due to large air volume.
Principle
The instrument uses the hot-sealing method for testing. The hot-sealing knife is heated by the heating element, and the sample is heat-sealed under the set temperature, time and pressure conditions, so as to determine the heat-sealing performance parameters of the material.
Applications
Plastic film substrate, Soft Encasement film, Spreader paper and other heat sealing film
Standards
QBT 2358、YBB 00122003、ASTM F2029
Steps
1. Connect the power supply and gas source (provided by the user).
2. According to the test requirements, set parameters such as heat sealing temperature, heat sealing time, and heat sealing pressure on the operation panel.
3. Select Automatic or Manual Operating Mode;
4. Place the sample under the heat sealing knife.
5. Start the equipment (foot switch or panel control can be used) for heat sealing test.
6. After the test is completed, the sample is taken out for analysis.
Notice
• Ensure that the air source pressure does not exceed 0.7 MPa.
• Please pay attention to anti-scalding when operating. The equipment has an anti-scalding design but still needs to be cautious.
The equipment has a leakage protection function, but it is still necessary to ensure a good grounding.
• Please use this equipment in a standard laboratory environment.
Please read the instructions carefully before use.
