Description

Manufacturing method of environmental humidity control article

technical field

The invention particularly relates to a manufacturing method of an environmental humidity regulating article.

Background technique

"Humidity" is an important factor affecting product packaging and storage shelf life in all walks of life. Every product requires a reasonable humidity range for storage. For example, the camera lens needs to be stored in the humidity range of 45-55%. If the ambient humidity is lower than this value, the rubber sealing ring will age; if the ambient humidity is higher than this value, the lens will fog up. The storage humidity of wooden musical instruments and other products is 45-55%. If the ambient humidity is lower than this value, the wood will be deformed, which will affect the sound quality; swell and damage wood products.

In order to control the environmental humidity from 45% to 55%, the commonly used method is to use humidity-conditioning silica gel to adjust the humidity of the environment, but the use of humidity-conditioning silica gel is not in line with green environmental protection products. A large amount of waste water is generated in the process of producing humidity-adjusting silica gel. In order to protect the environment, many silica gel raw material factories have been closed for rectification. This has led to various industries to include the least important desiccant products in the original bill of materials list in the purchase list of important materials.
