1. Purpose and Use Scope
The equilibrium pretreatment constant temperature and humidity chamber for formaldehyde test specimens is a test equipment specially produced for the 15-day pretreatment requirements of plate samples in the GB18580-2017 and GB17657-2013 standards. This equipment is equipped with one equipment and multiple environmental chambers. At the same time, the sample balance pretreatment is performed on different samples (the number of environmental chambers can be customized according to the site and customer needs). The number of test chambers has four standard models: 4 cabins, 6 cabins, and 12 cabins.

The formaldehyde test specimen balance pretreatment constant temperature and humidity chamber provides a separate test space, which can eliminate the mutual contamination of formaldehyde released by the formaldehyde test specimen, which affects the test results, and greatly improves the test accuracy. The multi-chamber configuration makes it possible to carry out cyclic tests, which greatly improves the test efficiency.

The specimens are placed at 23±1ºC, relative humidity (50±3)% for (15±2)d, the distance between the specimens is at least 25mm, so that the air can circulate freely on the surface of all specimens, and the indoor air at constant temperature and humidity The replacement rate is at least once per hour, and the mass concentration of formaldehyde in the indoor air cannot exceed 0.10mg/m3

1. Purpose and scope of use
The amount of formaldehyde released from wood-based panels is an important indicator to measure the quality of wood-based panels, and it is related to the environmental pollution of products and the impact on human health. The 1 m3 formaldehyde emission climate chamber detection method is a standard method for the detection of formaldehyde emission of indoor decoration and decoration materials widely used at home and abroad. It is characterized by simulating the indoor climate environment and the detection results are closer to reality, so it is true and reliable. This product is developed with reference to the relevant standards of formaldehyde testing in developed countries and the relevant standards of our country. This product is suitable for the determination of formaldehyde emission of various wood-based panels, composite wood floors, carpets, carpet pads and carpet adhesives, and the constant temperature and humidity balance treatment of wood or wood-based panels. It can also be used for volatilization in other building materials. Detection of harmful gases.

4. Working Principle and Features:

Working Principle:

Put a sample with a surface area of 1 square meter into a climate chamber with temperature, relative humidity, air flow rate and air replacement rate controlled at a certain value. The formaldehyde is released from the sample and mixed with the air in the box. The air in the box is regularly extracted, and the extracted air is passed through an absorption bottle filled with distilled water. All the formaldehyde in the air is dissolved into the water; the amount of formaldehyde in the absorption liquid and the extracted Air volume, expressed in milligrams per cubic meter (mg/m3), calculate the amount of formaldehyde per cubic meter of air. Sampling is periodic until the formaldehyde concentration in the test box reaches an equilibrium state.

Features:

1. The inner cavity of the box is made of stainless steel, the surface is smooth and does not condense, and does not absorb formaldehyde, ensuring the detection accuracy. The thermostatic box body is made of hard foam material, and the door of the box is made of silicone rubber sealing strip, which has good heat preservation and sealing performance. The box is equipped with a forced air circulation device (to form a circulating air flow) to ensure that the temperature and humidity in the box are balanced and consistent. The main structure: the inner tank is a mirror stainless steel test chamber, and the outer layer is an insulation box, which is compact, clean, efficient, and energy-saving, not only reducing This reduces energy consumption and reduces equipment balance time.

2. The 7-inch touch screen is used as the dialogue interface for the personnel to operate the equipment, which is intuitive and convenient. It can directly set and digitally display the temperature, relative humidity, temperature compensation, dew point compensation, dew point deviation, and temperature deviation in the box. The original imported sensor is used, and the control curve can be automatically recorded and drawn. Configure special control software to realize system control, program setting, dynamic data display and historical data playback, fault recording, alarm setting and other functions.

3. The equipment adopts industrial modules and imported programmable controllers, which have good operational stability and reliability, which can ensure the long-term trouble-free operation of the equipment, increase the service life of the equipment, and reduce the operating cost of the equipment. It also has fault self-checking and reminding functions, which is convenient for users to understand the operation of the equipment, and the maintenance is simple and convenient.

4. The control program and operation interface are optimized in accordance with relevant test standards, and the operation is simple and convenient.

5. Change the current reciprocating mist to control humidity, adopt the dew point method to control humidity, so that the humidity in the box changes steadily, thereby greatly improving the accuracy of humidity control.

6. The imported thin-film high-precision platinum resistance is used as the temperature sensor, with high accuracy and stable performance.

7. The heat exchanger with advanced technology is used in the box, which has high heat exchange efficiency and reduces temperature gradient.

8. Compressors, temperature and humidity sensors, controllers, relays and other key equipment components are all imported components.

9. Protection device: The climate tank and the dew point water tank have high and low temperature alarm protection measures and high and low water level alarm protection measures.

10. The whole machine is integrated and has a compact structure; installation, debugging and use are very simple.
