The use of special locks for museum display cabinets and three-level management locks (supervised by the state secret organ) meets

It is made of high-quality organic silicon with smooth surface, no obvious mechanical impurities and no acidic substances, and is

： The waist line of the display cabinet is made of 6063 independently developed aluminum profiles, the aging state is

We use cold-rolled steel plate, its thickness is more accurate, after cutting, grooving, bending, laser, punching and other professional settings,

It integrates the functions of refrigeration, heating, dehumidification and humidification, and is specially developed for the temperature and humidity control

Air purification system: It can purify formic acid, acetic acid, formaldehyde and volatile compounds, and effectively control the most direct

Constant temperature and humidity system: The humidity is accurately controlled within the set range of ± 1.5%. Under the circumstances
