1Plastic thermal aging roomStructural characteristics:

To facilitate the entry and exit of test samples into the workshop, a floor standing box structure is adopted. The floor standing warehouse board assembly structure can reduce the waste caused by equipment relocation and expansion in the later stage.

2. Composition of high-temperature aging room: heating, air duct circulation, lighting, exhaust, central control cabinet and other parts.

3. Adopting high-performance double-sided color steel rock wool storage board, with a fire resistance level of B, safe and environmentally friendly, efficient insulation, greatly reducing equipment energy loss while achieving energy-saving effects. The insulation thickness is 75mm.

4. The insulation board adopts 0.5mm board, top pull rod ceiling, and aluminum alloy reinforcement to ensure that the insulation board does not deform or burn at a temperature of 85 ℃.

5. The key components in the control system are all imported products, which ensures more stable and reliable performance compared to domestic instruments.

6. Safe output protection electrical appliances, protecting the safety of test specimens and testing systems, * protective measures, ensuring system safety and reliability.

7. Humanized software operation interface, easy to learn and use, automatic or manual generation of test reports.

8. Front door of the room: one. Adopting a single door structure, fully considering the convenience of sample vehicle entry and exit, anti reverse lock, ensuring smooth opening from the inside. The door of the test chamber is sealed with silicone rubber strip, which is resistant to high temperature, aging and has good sealing performance. Door width: 950mm, door height: 1800mm.

9. Room observation window: In order to facilitate the observation of the condition of the test samples inside the box, the observation window material is a hollow resistance film heated anti frost glass (230 * 300mm) made of multi-layer tempered glass. Compared with traditional ordinary glass in the industry, multi-layer tempered glass is not only solid and safe, but also can prevent surface fogging and maintain a clear view of the condition inside the observation box at all times.

10. Lighting device: One 40W/220V moisture-proof and explosion-proof lighting lamp is installed in the aging room, with a protection level of IP65 and an explosion-proof level in accordance with the GB3836-2000 "Electrical Equipment for Explosive Gas Environments" standard. It can be manually controlled by direct switch, avoiding the sample area in the middle of the box.

3、 Heating and air conditioning system:

1. Working principle: Forced ventilation and internal circulation, balanced temperature control method: The central control system amplifies, converts, and non linearly corrects the temperature signal collected inside the box, compares it with the set temperature value (target value), and obtains a deviation signal through PID operation. The output adjustment signal automatically controls the output power of the heater, achieving a dynamic balance between heating and heat dissipation in the laboratory, and ultimately achieving the goal of constant temperature.

2. Air circulation device: driven by a centrifugal fan.

3. Air heating method: using a dedicated spiral nickel chromium alloy resistive electric heater with a large heat dissipation area; PID+SSR drive control.

4. Wind turbine constant temperature system; The wind duct system complies with the "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" GB50243-2002 standard, and is usually composed of a circulation system, a heating system, and an over temperature exhaust system. The circulation system, over temperature exhaust system, heating system, and supporting air duct system use circulating fans and supporting air ducts for circulation, ensuring uniform temperature in the testing area. The heating system uses electric heaters, which are placed in the circulating air duct on the aging roof and surrounded by fire-resistant insulation materials. Using PID temperature module control, the power of the heater is automatically adjusted according to the fluctuation of indoor temperature when the temperature reaches the required temperature of the product, in conjunction with the insulation performance of the insulation board, to accurately stabilize the indoor temperature at the set temperature value. The room temperature can be increased to the set degree within the specified time, and the heater stops heating when the temperature rises to the set value The heater has an overheat protection device. If the customer's own product heats up, an overheat exhaust system is used, using a low-noise fan for exhaust. The temperature control process is repeated: when the heater starts heating and the temperature reaches the set value, the heater stops heating. During the aging process of the product, it always maintains a circulating state to ensure temperature balance. The entire system has the characteristics of stable performance, precise control, small temperature fluctuations, high balance, and low noise.

5. Noise treatment: High quality circulating fans with low decibels are used, and the air ducts are wrapped in 3mm thick asbestos, which not only provides insulation but also reduces noise. According to acoustic principles, all dynamic parts are soft connected with canvas and springs, striving to reduce noise to the standard.

6. Energy saving control: The equipment adopts an air circulation system, and the wind pressure and volume generated by the fan are large, resulting in high heat transfer efficiency.

7. Reliable noise reduction measures: The internal edges of the fan cabinet are equipped with honeycomb shaped sound-absorbing sponge and soundproof rubber to ensure maximum noise reduction.

4、 Building materials:

The house is assembled using high-performance double-sided color steel rock wool insulation storage panels, with a thickness of 75mm for the panels and 0.5mm for the color steel plates. The entire storage body is supported by a steel frame structure and fixed with aluminum profiles. The top of the storage can be operated directly without other auxiliary measures, making it convenient for equipment maintenance and repair. The interior and exterior of the storage body are wrapped with aluminum profiles or stainless steel plates; Seal the joint with glass glue to effectively ensure the sealing and aesthetics of the room. The equipment is installed with double doors, which are made on site according to the actual situation. The combustion performance of the building materials meets the requirements of the "Classification of Combustion Performance of Building Materials",
