What is a semi-automatic bursting strength testing machine?
In industrial production, the bursting strength of materials is one of the important indicators to measure their quality. As an efficient testing equipment, the semi-automatic bursting strength testing machine is widely used in paper, cardboard, packaging materials and other industries. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of semi-automatic burst strength testing machines.
1. Definition of semi-automatic burst strength testing machine
Semi-automatic bursting strength testing machine is a device used to measure the bursting strength of materials under pressure. It applies uniform pressure to the sample through a hydraulic or pneumatic system and records the maximum pressure value when the sample ruptures, thereby evaluating the material's anti-rupture performance.
2. Working principle
The working principle of the semi-automatic burst strength testing machine mainly includes the following steps:
1. Specimen fixation: Fix the material to be tested on the test fixture.
2. Pressure application: Apply gradually increasing pressure to the specimen through a hydraulic or pneumatic system.
3. Data recording: The instrument automatically records the maximum pressure value (unit: kPa or psi) when the sample ruptures.
4. Result output: Test data can be exported through the display or connected to a computer.
3. Application fields
Semi-automatic bursting strength testing machines are widely used in the following industries:
| Industry | Test materials | Test standards |
|---|---|---|
| paper making | paper, cardboard | ISO 2758, GB/T 454 |
| packaging | Corrugated boxes, plastic films | ASTM D2210 |
| textile | Non-woven fabrics, composite materials | ISO 13938-1 |
4. Comparison of popular models in the market
The following is a comparison of the popular semi-automatic burst strength testing machine models and their parameters on the market recently:
| Model | pressure range | Accuracy | Price (yuan) |
|---|---|---|---|
| BUR-100A | 0-6000kPa | ±0.5% | 25,000-30,000 |
| PT-300S | 0-10000kPa | ±0.3% | 35,000-40,000 |
| MST-200 | 0-8000kPa | ±0.4% | 28,000-32,000 |
5. Purchase suggestions
When purchasing a semi-automatic burst strength testing machine, you need to consider the following factors:
1.Testing requirements: Select the appropriate model according to the pressure range of the material.
2.Accuracy requirements: High-precision equipment suitable for laboratory-level testing.
3.budget: Comprehensive evaluation based on equipment performance and price.
4.After-sales service: Choose a brand that provides technical support and warranty services.
6. Conclusion
The semi-automatic burst strength testing machine is an important tool in the field of material testing. Its efficiency and accuracy provide reliable data support for industrial production. With the advancement of technology, such equipment will be more intelligent and automated in the future to further meet diverse testing needs.
