In some areas, the cold air only leaves in March every year. Although the temperature rises in April, Qingming and Guyu are rainy periods. Coupled with the plum rainy season in May and June, it can be said that the whole first half of the year is relatively humid. The rise of temperature brings about the increase of air humidity. Water droplets can even be seen on the surface of walls and floor tiles, which are wet everywhere. In northern China, most areas have entered the flood season in July and August. The increase of rain has increased the humidity of the air.
Under such climatic conditions, if the moisture-proof protection of laser cutting machine equipment is neglected, it may lead to problems such as black screen of console computer, failure of industrial control computer to start, laser alarm, switch trip and so on, which may affect the production. Therefore, doing a good job in the moisture-proof protection of the laser cutting machine is also “escort” for the normal operation of the laser cutting machine.
Reduce indoor humidity
(1) moisture proof and dehumidification of activated carbon.
Activated carbon has many uses. It can not only dehumidify, but also purify the air and remove peculiar smell. The main ingredients of dehumidification boxes sold in supermarkets are calcium fluoride and activated carbon. This is a good dehumidification product, but this dehumidification method is only applicable to small spaces, such as placed in the control cabinet and electrical cabinet of the cutting machine, which can effectively absorb moisture and remove peculiar smell. In wet weather, using activated carbon to prevent moisture can reduce the environmental humidity in the control cabinet and electrical cabinet and reduce the probability of equipment failure due to humidity.
(2) open the window to breathe in fine weather.
When it’s raining or cloudy outside, it’s best not to open the window (especially the window facing south) to prevent the hot and humid air from entering the house. When the weather is fine, you can selectively (open windows facing other directions) open windows for ventilation to reduce indoor humidity.
⑶ quick lime dehumidification.
According to the data, every 1kg quicklime can absorb about 0.3KG of water in the air. Quicklime can absorb moisture well. If the room is wet and the ground condenses, quicklime can also be put into cloth bags and placed at each corner of the workshop to achieve the effect of rapid moisture removal and drying.
