Ink in the storage process need to pay attention to the following issues:

 

1. temperature control

suitable temperature range

Usually the ink should be stored in an environment of 15°C -25°C. Too high temperature may cause the solvent in the ink to volatilize too fast, so that the ink thickens or even dry; too low temperature may make the ink fluidity worse, affecting the performance.

Avoid extreme temperatures

Keep away from heat sources, such as heating equipment, direct sunlight and other high-temperature areas. At the same time, it is necessary to prevent the ink from being exposed to a cold environment, especially in winter, and the ink should be prevented from freezing at low temperatures.

 

2. humidity control

Suitable humidity range

In general, the relative humidity should be controlled between 40%-70%. Excessive humidity will cause the ink to absorb moisture in the air, resulting in a decrease in the viscosity of the ink, a lighter color, a slower drying speed, and may even cause deterioration of the ink.

Moisture-proof measures

The warehouse where the ink is stored should be kept dry and ventilated, and dehumidification equipment can be used to control humidity. The ink should be stored in a well-sealed container to prevent moisture in the air from entering.

 

3. light protection

Avoid direct sunlight

Ultraviolet rays in the sun will cause chemical changes in the pigments and connectors in the ink, resulting in color fading and ink aging. Therefore, the ink should be stored in a dark place, avoid direct sunlight.

Indoor light control

Even indoors, avoid prolonged exposure to strong light. You can use curtains or shade cloth to shield the window, reduce the impact of light on the ink.

 

4. container selection and sealing

Suitable container

A container with good sealing and corrosion resistance should be selected to store the ink. Common containers are plastic barrels, metal barrels and so on. The size of the container should be selected according to the amount of ink used to avoid waste or inconvenience caused by too large or too small containers.

Good sealing

After filling the ink, you must ensure that the container is tightly sealed. Seals such as sealing caps and sealing rings can be used to prevent air, moisture and impurities from entering the container.

 

5. to prevent pollution

Clean storage environment

Storage ink warehouse should be kept clean, avoid dust, debris and other pollution ink. Regularly clean the warehouse, clean the dust on the ground and shelves.

Avoid cross-contamination

Different types of ink should be stored separately to avoid mixing or contamination with each other. In the use of ink, also pay attention to avoid the use of contaminated tools or equipment.

6. periodic inspection and mixing

Periodic inspection

Regularly check the storage state of the ink, and observe whether the ink has deteriorated, dry knot, precipitation and other phenomena. If problems are found, measures should be taken in time to deal with them.

Stir evenly

For ink stored for a long time, precipitation may occur. Before use, the ink should be stirred evenly to ensure stable performance of the ink. Stirring may be performed using a stirrer or manual stirring.

 

7. Safety Precautions

Fireproof and explosion-proof

Ink contains flammable solvents, so the storage ink warehouse should be away from fire, heat, smoking and the use of open flame. At the same time, should be equipped with the corresponding fire fighting equipment, such as fire extinguishers, fire sand and so on.

Good ventilation

Ensure that the warehouse where the ink is stored is well ventilated to discharge the volatile solvents and odors in the ink and reduce safety hazards. Ventilation can be installed or windows opened for ventilation.

In short, the correct storage of ink can ensure the stable performance of the ink, extend the service life of the ink, and improve the printing quality. During the storage process, the temperature, humidity, light and other conditions should be strictly controlled, a suitable container should be selected and sealed to prevent pollution, regular inspection and mixing, and safety precautions should be paid attention.
