Thermal Insulation Rock Wool Thermal Load Tester: Ensuring High-Temperature Performance

The Thermal Insulation Rock Wool Thermal Load Tester is an essential piece of equipment designed to accurately determine the temperature at which rock wool insulation shrinks under a specified load when subjected to a controlled heating rate. This critical test is fundamental for assessing and guaranteeing the long-term performance and stability of rock wool in high-temperature thermal insulation applications, where maintaining structural integrity under heat and load is paramount.

Why Thermal Load Testing is Crucial for Rock Wool

Rock wool is a widely used thermal insulation material due to its excellent fire resistance and insulating properties. However, its performance can be compromised if it shrinks or deforms at elevated temperatures under applied pressure. This shrinkage can lead to:

Reduced Insulation Effectiveness: Gaps or thinning in the insulation layer decrease its thermal resistance.

Structural Instability: Compromised integrity in the insulation system.

Safety Concerns: Potential for heat transfer in critical applications.

Our Thermal Load Tester provides the objective data needed to validate rock wool's suitability for demanding environments, ensuring it performs reliably throughout its intended lifespan.
 

Precision Testing Method

The tester operates by precisely controlling the heating process and applied load:

Sample Preparation: A rock wool sample is prepared and placed within a test barrel of 48mm ± 1mm.

Specified Load Application: A consistent 490 Pa pressure is applied to the sample, simulating real-world load conditions that insulation might experience.

Controlled Heating: The sample is then heated at a multi-point programmed rate:

Room temperature to 400°C at 5°C/min

400°C to 800°C at 3°C/min This controlled ramp ensures a precise and reproducible thermal exposure.

Shrinkage Measurement: The instrument continuously monitors the sample as it heats, detecting the temperature at which shrinkage begins and its progression. The scale measuring range extends from room temperature up to 900°C, allowing for comprehensive high-temperature evaluation.

Data Acquisition: An integrated single-chip computer manages the multi-point program heating and data collection, ensuring accuracy and consistency.
