Embodiment 1

[0028] A method for manufacturing environmental humidity control articles for manufacturing environmental humidity control articles that control the environmental humidity at 45-55%, including the following steps:

[0029] Step one, configure humidity control fluid

[0030] At least one organic acid salt, at least one polyol and water are configured as a humidity control liquid at a temperature not lower than 40°C.

[0031] Step two, apply humidity control liquid on the substrate

[0032] The substrate is coated in the humidity-conditioning liquid at a speed of 5-10m / s, and the coating length is 3-10m, so that 0.64 g of the humidity-conditioning liquid is loaded per cubic centimeter of the substrate.

[0033] Step three, cut the substrate

[0034] The substrate is cut so that the substrate reaches a predetermined size. In this embodiment, the thickness of the substrate is greater than 1 mm. The predetermined size can be set according to the needs of users, and can be from 1 cm×1 cm to 10...

Abstract

The invention provides a manufacturing method for an environment humidity regulating item, and the manufacturing method is simple in process, adopts cheap raw materials, is good in humidity regulation, and saves energy. The manufacturing method is used for regulating and controlling environment humidity to be 45-55%, and the manufacturing method comprises the following steps: step I, preparing a humidity regulating composition, and preparing at least one chlorate and water into humidity regulating liquor at a temperature not lower than 40 DEG C; and step II, coating the base material at speedof 1-15 m / s in the humidity regulating liquor at a temperature not lower than 40 DEG C, and enabling every cubic centimeter of the base material to load with 0.64 g of the humidity regulating liquor,wherein organic acid salt is at least one of sodium lactate, potassium lactate and sodium formate; number of carbons in polyhydric alcohols is not greater than 5; the mass fraction of organic acid salt is 30.6-58.8%; and the mass fraction of the polyhydric alcohols is 9.3-26.7%.

Description

Technical field [0001] The invention specifically relates to a method for manufacturing environmental humidity control articles. Background technique [0002] "Humidity" is an important factor affecting product packaging and storage shelf life in various industries. Every product needs a reasonable humidity range to store. For example, the camera lens needs to be stored in a humidity range of 45 to 55%. If the ambient humidity is lower than this value, the rubber sealing ring will age; the ambient humidity higher than this value will cause fogging. The storage humidity of wooden musical instruments and other products is 45 to 55%. If the humidity is lower than this value, the wood will be deformed, which will affect the sound quality; if the humidity is higher than this value, the wood will become mildew, or the wood will absorb a lot of moisture. The swelling will damage the wood products. [0003] In order to control the environmental humidity from 45% to 55%, the commonly use...
