Some suggestions on purchasing second-hand dehumidifiers

Every year in the rainy season, humid air constantly enters the room, which leads to very humid home, moldy clothes, and water stains everywhere on the walls and floors, which brings great troubles to life. Therefore, people will think of many methods of dehumidification and moistureproof. A direct and practical method is to configure a suitable dehumidifier. Under the condition that the room is relatively closed, the dehumidifier can dehumidify the excess water in the indoor air, accurately control the indoor humidity, and keep it in an ideal environment. However, because the dehumidifier belongs to professional dehumidification equipment, the price is relatively high, so at present it is mainly enterprise users, and the ordinary household use of citizens is far from universal. Many citizens buy and use second-hand dehumidifiers in order to reduce their adult life. Therefore, this paper gives some suggestions for the machine friends who are going to buy second-hand dehumidifiers, hoping to help everyone.

First, try not to buy a second-hand dehumidifier after maintenance. Maintenance can be divided into formal maintenance and informal maintenance. If the second-hand dehumidifier is processed by informal maintenance by non-professionals, its maintenance process is definitely not standardized. Firstly, there is no professional technology, and secondly, there is no professional maintenance testing equipment. In this case, the quality of the repaired machine is seriously reduced, the dehumidification effect is greatly discounted, and there are great security risks.

Second, try not to buy a second-hand dehumidifier that is close to its service life. Although dehumidifiers are durable products, they also have a service life, which is generally 5 to 6 years. High-grade dehumidifiers are only maintained for about 7 to 8 years. If they exceed the service life, they will eventually die. Therefore, when buying second-hand dehumidifiers, you should pay attention to the production date and try not to buy products that are close to the use limit. Otherwise, if you buy them back, it will not take long, and there will be many problems, and the basics will be completely unusable and become a pile of scrap iron.

Third, try not to buy three no products. No means no invoice, no brand and no warranty card. Once the third-hand dehumidifier breaks down, there is no professional after-sales service, so you should buy a second-hand dehumidifier or a brand dehumidifier. The dehumidifiers of big brands generally provide after-sales service for life-long maintenance, while small brands or unknown brands, not to mention second-hand, are newly bought machines, and you may not find the after-sales service of the original factory in the second year. Without professional maintenance, the dehumidifier can not achieve the expected use effect, but also consumes energy and electricity, which makes users lose more than they gain.

Finally, Xiaobian gives you a piece of advice: Although second-hand dehumidifiers are cheap, consumers should buy them carefully! The main source of second-hand dehumidifiers is through recycling waste and then repairing and refitting, and the price is cheaper than that of new dehumidifiers. However, because the repair and refitting are not completed by professionals, there are great security risks and the service life is short, so try not to buy second-hand dehumidifiers in case the loss outweighs the gain.

Application of dehumidifier in moisture-proof of carton

Yesterday, Miss Chen dug out the outer packaging of more than a dozen large and small cartons in her home, and prepared to tidy it up to make more space. Just after the Double Twelve, there are not a few "hands-snatching parties" in the same situation. At present, online shopping has become a popular consumption mode, and carton packaging accounts for more than 90% of the packaging mode of goods. Therefore, the inventory management of cartons has become a compulsory topic for many businesses, because the outer packaging such as cartons not only plays a role in protecting products, but also directly affects customers' goods.

As we all know, cartons have strong hygroscopicity. In rainy and humid weather, the humidity rises sharply. If the air is too humid, it will easily lead to moisture absorption of cartons, which will lead to problems such as softening and mildew. If the quality of internal goods is affected by problems such as carton packaging, it will lead to adverse consequences such as customer complaints or returns. Chuantai dehumidifier is aimed at this situation, helping users to better protect paper packaging such as cartons and reduce unnecessary losses.

It is understood that the storage conditions and storage period of corrugated boards and cartons: the storage environment of corrugated boards and cartons should be kept ventilated, dry and away from fire sources to avoid rain, exposure and pollution. The stacking height should be more than 15cm from the ground, and materials that are not easy to transfer heat and moisture, such as wooden or plastic cardboard, should be used as the mat. Measurement of warehouse temperature and humidity: Dry wet-bulb thermometer is usually used to measure air temperature and humidity. Outside the warehouse, in order to avoid the invasion of sunlight, rain and dust, the wet and dry meters should be placed in the louver box. The height of the bulb of the thermometer in the louver is 2 meters from the ground, and the door of the louver should be placed to the north to prevent direct sunlight during observation. The box should be kept clean and free of sundries, so as to avoid air circulation. In the warehouse, the hygrometer should be placed in a place where the air is ventilated and not exposed to sunlight, and it should not be hung on the wall, and the height from the ground is about 1.5 meters.

If it is a medical cardboard box, the requirements are more stringent. Usually, it is required to have a special storage warehouse, and the temperature and humidity can be controlled. In addition, it is necessary to equip pest control equipment such as pest control lights to prevent the cardboard box from being polluted. Each cardboard box with a card board needs a certain space interval to ensure good ventilation. The storage period of corrugated board and carton should not be more than half a year. The reason why the packaging box burst is that the water content of cardboard is not enough. Generally, the water content is 8-12%, which is the water content of normal production. Below this value, the phenomenon of line bursting and warping will occur. Generally, the temperature is controlled by natural ventilation system or central ventilation system. Due to regional differences, the humidity has changed greatly from season to season, so special humidification equipment is generally needed to solve it. The indoor humidity is generally kept at 60-65%RH. As an important aspect of warehouse management, the temperature and humidity management of the warehouse is very important, and it is necessary to master the relevant knowledge of air temperature and humidity.

Chuantai dehumidifier is a kind of special equipment for controlling the indoor humidity, which can accurately and automatically adjust the indoor relative humidity and keep the indoor humidity in a relatively ideal state. Its working principle is to monitor the indoor humidity all the time. Once the humidity exceeds the preset range, it will be dehumidified immediately to convert the excess water in the air into liquid water and discharge it indoors, so as to keep the indoor dry environment. When it meets the requirements, it will automatically stop dehumidifying and enter the standby state. Everything is automatically controlled by the microcomputer system in the dehumidifier from beginning to end, without the need for workers to be on duty, which is intelligent and efficient.

Chuantai dehumidifier has been widely used in carton storage, which is closely related to the rich product models. Different areas need different moisture content, which requires a relative amount of dehumidification. There are more than 40 sizes and models of Chuantai dehumidifier, which can meet the dehumidification needs of users in different areas. The model and dehumidifying amount of dehumidifier are suitable for the indoor volume. Dehumidification is not only efficient, but also more energy-saving and environmentally friendly. For example, in a small warehouse with a site of 50 square meters, the dehumidifier equipped with 26 liters will be too small, and the use effect will be poor. The machine equipped with 130 liters will be too big, wasting costs, and it is more suitable for the dehumidifier equipped with 50 liters or 90 liters.

Summary: Dehumidifier is a durable product, which is configured to meet the demand. Therefore, in addition to configuring professional dehumidifying equipment, it is also necessary to select the corresponding dehumidifier model and a good brand supplier, and a brand with strength and reputation will not only ensure the product quality, but also improve the after-sales service.
