How to do, how to determine and control warehouse humidity
Warehouse temperature humidity is how much, most of the warehouse stock is cardboard box, easy to become soft and damp. So what is the temperature humidity that the carton should keep?
In addition, if the humidity is too big, how should deal with?
Knowledge of temperature and humidity management in warehouse
As an important aspect of warehouse management, the temperature and humidity management of warehouse is very important.
Need to master the relevant knowledge of air temperature and humidity.
Determination of temperature and humidity in warehouse:
Dry wet - bulb thermometer is used for the determination of air temperature and humidity.
Outside the library, in order to avoid the sun, rain, dust invasion, the wet and dry tables should be placed in the screen.
The ball of the thermometer in thermometer screen is 2 meters above the ground level.
The door of shelters shall be placed in the north to prevent direct sunlight from being observed.
The box should be kept clean, no sundries, so as not to cause air circulation.
In the library, the dry and wet meters should be placed in the air circulation, not exposed to the sun.
Don't hang on the wall. it's about 1.5 meters above the ground.
Daily monitoring and recording of temperature and humidity in the library must be conducted on a daily basis. Generally, from 8 a.m to 10 a.m, and from 2 p.m to 4 p.m. Record the data to be properly preserved, regular analysis, take out the law, in order to grasp the initiative of commodity preservation.
Control and regulate the temperature and humidity of the warehouse:
In order to maintain the quality of the warehousing goods and create an environment suitable for commodity storage,
When the temperature and humidity of the warehouse are suitable for commodity storage, we should try to prevent the adverse effects of the outside climate on the library.
When the temperature and humidity in the library are not suitable for commodity storage, it is necessary to take effective measures in time to adjust the temperature and humidity in the library.
Practice has proved that the combination of seal, ventilation and moisture absorption is an effective way to adjust the temperature and humidity in the library.
Adopting the sealing method, should be combined with ventilation, moisture absorption and other methods.
If used properly, can receive moistureproof, mildew, heat protection, anti - melting, anti - drying, anti - frost, anti - corrosion, anti - insect and other effects.
Note: check the quality, temperature and water content of the goods before sealing.
Such as the discovery of mildew, sheng, fever, water, and so on can not be sealed.
It is found that the water content of goods exceeds the safety range or the packing material is too wet, and it should not be sealed.
To determine the timing of the seal based on the performance and climate of the product.
The products of fear of tide, fear of melting, be afraid of, should be sealed at relatively low relative humidity.
Commonly used sealing materials, plastic film, moisture - proof paper, linoleum, reed mat and so on.
These sealing materials must be dry and clean and have no smell.
Sealed commonly used methods include whole warehouse seal, small chamber seal, according to seal, and by shelf, according to the seal and so on.
Ventilation is the air pressure difference formed by the different air temperature inside and outside of the library, which makes the air form convection inside and outside the reservoir to achieve the purpose of adjusting the temperature and humidity in the library.
The larger the temperature difference inside and outside the library, the faster the air flow. If there is wind outside the library, the pressure of wind can accelerate the convection of the air inside and outside the library.
But the wind cannot be too big ( more than 5 wind, more dust ).
Properly ventilated, not only can adjust and improve the temperature and humidity in the library, but also timely distribute the surplus water of goods and packaging materials.
According to the purpose of ventilation, it can be divided into two kinds: ventilation cooling ( or warming ) and utilization of ventilation.
absorption of moisture
In the rainy season or rainy weather, when the humidity of the library is too high, not suitable for commodity storage, and the external humidity is too large, it is not appropriate to carry out the ventilation and disperse tide, can use moisture absorption method to reduce the humidity inside the storehouse.
The warehouse of many large retail enterprises, the general use of mechanical moisture absorption method. Use xishiji to put the wet air in the library through the suction fan, and suck it into the xishiji cooler to condense it into water.
Xishiji is generally suitable for cotton, needle cotton, expensive department store, medicine, instruments, electrical equipment and tobacco sugar storage library, the effect of moisture absorption is better.
Your difficulties, I feel the same, our warehouse began to be so, wet, everything has long hair.
Later asked a lot of people, they recommended I use a dehumidifier.
Purchase of pine warehouse industrial dehumidifier.
They calculated the humidity, configured the model, and now there is no such worry.
In case of not know also no problem, their Dehumidifier are microcomputer automatic control of humidity, it is convenient to use.
Specific I don't say more, you contact yourself.
