Application of temperature and Humidity Chamber in manufacturing product inspection

The constant temperature and Humidity Chamber can accurately simulate complex natural environments such as low temperature, high temperature, high temperature humidity, low temperature humidity, etc., so as to test the cold resistance, heat resistance, dry resistance and humidity resistance of the product, and improve the performance of the product. make them more durable.

Specifically, daily production and life, electronics, electrical, communications, instrumentation vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace, bathroom and other product quality inspections all need to use constant temperature and Humidity Chambers to help people produce and experiment.

Electronics, electrical, semiconductor, communication and instrumentation industries

The electronics, semiconductor, electrical, communication, and instrumentation industries all require delicate electronic components with high requirements on temperature and humidity conditions. For example, for common circuit boards, whether it can meet the required temperature is very important. This is because component life is reduced by approximately 10% to 30% for every 10°C increase in ambient temperature.

Tapes, disks, and CDs started to fail when the temperature was sustained above 37.8°C, and completely failed when the temperature was consistently above 65.6°C.

The battery is a device that is very sensitive to the ambient temperature. For every 10°C increase in the operating temperature from 25°C, the service life will be reduced by 50%. Similarly, when the operating temperature is lower than 25°C, the discharge capacity of the battery will decrease as the temperature drops.

Although the polarizers and filters of glass substrates and liquid crystal displays are cleaned and dried during the production process, they will still be affected by moisture after cooling, which reduces the pass rate of products. Therefore, after cleaning and drying, it needs to be placed in a dry environment with a humidity of 40% RH.

Therefore, whether it is the preservation of electronic components and magnetic media, or the production of semiconductors and LCDs, constant temperature and Humidity Chambers are very important instruments.

Medical, biopharmaceutical industry

In medicine, medical thermostats are mainly used for storage and transportation of drugs and reagents, refrigeration and heat preservation of vaccines and blood, heating of dialysate, heating of normal saline, etc. In the biopharmaceutical industry, the constant temperature and Humidity Chamber can provide a stable temperature and humidity environment to simulate various climatic conditions, especially suitable for sample stability experiments, long-term experiments, balance experiments to determine the stability and life of drugs, etc.

Sanitary products industry

An important material used in sanitary products such as sanitary napkins and diapers are breathable membranes. A qualified breathable membrane is not stuffy when used, does not leak when absorbing liquid, is comfortable and safe when in contact with the human body, and will not cause allergies or other injuries. Moisture permeability is a key indicator of whether the breathable film is qualified.

Automobile industry

As an everyday means of transportation, cars are exposed to a wide range of temperature, humidity, pressure and altitude. Auto parts, paints and coatings undergo very rigorous testing to determine their compliance.

Heat, cold, heat and humidity or just these factors, most automotive components are exposed to a wide range of environmental influences throughout their life cycle. These environmental factors can affect its function or appearance, thereby shortening its service life. In addition, these components are repeatedly subjected to severe mechanical loads during daily use and need to be safe and reliable even under extreme conditions.

Therefore, different automotive components and materials undergo rigorous durability testing to determine their resistance to environmental influences and temperatures. The temperature and humidity Test Chamber is used to test the influence of temperature and humidity environment on auto parts.

In addition, constant temperature and Humidity Chambers are also widely used in laboratories, generally used for plant cultivation, breeding experiments, bacterial and microbial cultivation, fermentation, various constant temperature experiments, environmental experiments, water quality analysis, BOD determination, denaturation of microbial cultures Test and store.
