1m formaldehyde emission detection climate chamber FD-1

one Equipment Introduction

Formaldehyde has a significant impact on human health and is recognized as a strong carcinogen by the World Health Organization. With the improvement of people's living standards and the enhancement of health awareness, it is particularly important to detect the release of environmental pollutants.

In daily life, wooden products, coatings, adhesives, paints, flooring, furniture, carpets, car interiors, etc. used in home decoration are formaldehydeVOCOne of the main sources of volatile organic compounds (VOCs) is long-term exposure, especially in densely stored and enclosed indoor or vehicle environments, where the concentration of pollutants can be higher and pose greater harm to human health.

1 m3The climate chamber detection method for formaldehyde emission is widely used both domestically and internationallyThe standard method for formaldehyde emission detection is characterized by simulating indoor climate environment, and the detection results are more realistic and reliable. This climate chamber is suitable for the determination of formaldehyde emissions from various indoor decoration materials, constant temperature and humidity balance treatment of wood or artificial boards, and can also be used for the detection of volatile harmful gases in other building materials.

two Equipment features

1. The main power supply is single-phase220VAdopting advanced energy-saving control mode, the average operating power consumption of the whole machine is as low as1KW；

2. The main electrical components are all from the German Siemens brand, the frequency converter is from the Japanese Yaskawa brand, and the air flow meter is from the American Silicon Xiang brand, ensuring stable and reliable operation of the entire machine;

The air flow rate is adjusted by the manual control valve on the front panel of the device, and the wind speed can be directly set through the parameters on the touch screen interface;

4. The equipment gas path adopts stainless steel pipes and sleeve type joints to ensure the sealing and cleanliness of the gas path;

5. The inner wall of the work box is made of stainless steel mirror, fully welded and polished;

6. The air intake system passes through an air filtration device to ensure the cleanliness of the air supply;

7. Equipped with a set of temperature, humidity, and wind speed calibration racks, and leaving an air flow calibration port;

8. Realize water level shortage alarm and one click automatic water filling function in the water tank, saving manpower;

9. Implement real-time monitoring of the internal temperature of the water tank, and immediately sound an alarm in case of any abnormalities;

10. Automatic data recording, real-time curve browsing, historical data storage, browsing, exporting（USBStorage devices);

11. The following control methods can be implemented (default local control method, other methods are optional)

a)Local control: operate the device directly on the touch screen;

b)Remote control: can be accessed from anywhereWEBOr mobile phoneAPPRemote access and control of devices.

3 Equipment Technical Specifications

five Equipment working principle

This climate chamberAdopting evaporator circulation temperature control, with circulating water at a certain temperature inside the evaporator,Control the temperature inside the working chamber by adjusting the water temperature in the temperature water tank.

Humidity inside the climate chamberUsing dew point temperature control method,The water at a certain dew point temperature is fully exposed to clean air in the water spray tower, producing saturated water vapor at the same temperature. When it enters the climate chamber at a certain temperature, a relative humidity corresponding to the temperature is produced.The magnitude of air exchange rate also affects the stability time of humidity inside the box.

The air circulation inside the climate chamber is controlled by a frequency converter and sucked in by the axial flow fan at the rear, and then evenly discharged from the porous plate at the top, with good circulation effect. The replacement of air is achieved by using an electromagnetic compression pump to supply gas, and the needle valve of the flow meter is used to regulate the gas flow rate.
