Insulated Thermal Shock Test Chambers For Processing Wood Packaging Material Test

1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Construction
  • The test chambers are built with a heavy-duty steel frame that provides exceptional rigidity and stability. The frame is coated with a corrosion-resistant finish to enhance its longevity. The chamber walls are made of high-quality insulation materials, which minimize heat transfer and maintain precise temperature differentials. The insulation is carefully selected to withstand the rigors of continuous testing and prevent any external factors from interfering with the internal test environment. The chamber is also equipped with a hermetic door seal, ensuring a leak-free enclosure and consistent test conditions.
• Precision Temperature Control System
  • The chambers feature a highly accurate temperature control system. They can achieve a wide temperature range, typically from -60°C to +180°C. The temperature control is accurate to within ±0.5°C, allowing for precise simulation of extreme temperature conditions. The system utilizes advanced refrigeration units, electric heaters, and temperature sensors. The sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make rapid and precise adjustments. This level of temperature control is crucial for accurately replicating the thermal shock that wood packaging may experience in real-world scenarios.
• Rapid Temperature Transition Capability
  • One of the key features of these chambers is their ability to effect rapid temperature transitions. They can change the temperature within the chamber at a rate of up to 30°C per minute. This rapid rate of change is essential for simulating the sudden temperature fluctuations that wood packaging might encounter, such as when moving from a cold storage facility to a hot transportation vehicle or vice versa. The rapid transition capability ensures that the wood is subjected to the most realistic and challenging thermal stress conditions, allowing for a comprehensive evaluation of its performance.
• Customizable Interior and Fixtures
  • The chambers offer a customizable interior space to accommodate different sizes and shapes of wood packaging samples. They can be equipped with adjustable racks, shelves, and mounting fixtures, allowing for flexible test setups. The interior surfaces are made of non-corrosive and non-reactive materials to prevent any contamination or interaction with the wood samples. Additionally, the chambers can be fitted with various accessories, such as cable ports for sensor connections, viewing windows for visual inspection, and access doors for easy sample loading and unloading.
• Advanced Control and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel and a sophisticated data acquisition system. The control panel allows operators to easily set and adjust the temperature parameters, test durations, and temperature transition rates. It provides real-time display of the current test conditions and any alarms or warnings. The data acquisition system records all relevant test data, including temperature profiles, temperature change rates, and any physical changes or damage observed in the wood samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system also has the ability to generate detailed test reports in various formats, such as PDF or Excel.

3. Specific Parameters

• Maximum Temperature Swing Rate
  • As mentioned, the chambers can achieve a maximum temperature swing rate of 30°C per minute. This rate is crucial for testing the ability of wood packaging materials to withstand sudden and extreme temperature changes. For example, in international shipping, wood pallets may be exposed to rapid temperature changes when moving from cold regions to warm ones or during the transition from a refrigerated storage area to a non-refrigerated transportation mode.
• Temperature Control Range
  • The wide temperature control range of -60°C to +180°C allows for the simulation of a vast array of environmental conditions. Wood packaging used in arctic regions may need to endure extremely low temperatures, while those in tropical or industrial settings may face high temperatures. Testing across this range ensures that the wood's integrity and performance are evaluated under the most extreme and diverse thermal scenarios.
• Testing Volume and Payload Capacity
  • The chambers offer customizable testing volumes, with options ranging from 1 m³ to 20 m³. The payload capacity can be adjusted according to the size and weight of the wood packaging samples, with a maximum capacity of up to 2000 kg. This flexibility allows for the testing of a wide variety of wood packaging forms, from small wooden crates to large palletized loads.
• Heating and Cooling Rates
  • The heating rate can reach up to 15°C per minute, and the cooling rate can be as fast as 20°C per minute. These rates contribute to the overall rapid temperature transition capability of the chamber and are essential for accurately replicating the thermal shock conditions that wood packaging may face.

4. Product Functions

• Accurate Evaluation of Wood Packaging Durability
  • The primary function of the chambers is to provide a precise and reliable assessment of the durability of wood packaging materials under thermal shock conditions. By subjecting the wood to rapid temperature changes, it determines how well the material can resist cracking, warping, and other forms of damage. This information is invaluable for manufacturers to improve their wood treatment processes, select appropriate wood species, and enhance the overall quality of their packaging. For example, if a particular type of wood is found to be prone to cracking after thermal shock testing, manufacturers can explore alternative wood sources or modify their treatment methods to increase its resistance.
• Quality Control and Compliance Testing
