Solution

• 1.The causes of mold growth on paint usually include factors such as high environmental humidity, poor ventilation, dry storage environment, residual organic matter, and insufficient lighting. In a high-humidity environment, the paint surface easily absorbs moisture, providing conditions for the growth of mold;

  
  

  According to our company’s experimental research and analysis on most boards and paints, combined with our company’s experience in anti-mildew technology:

  
  

  2.2 Strengthen environmental control

  
  

  2.2.1 During the product production process, it is necessary to strengthen the control of pollutants in the product production environment and reduce suspended solids in the air. Necessary anti-static measures can be taken to reduce the accumulation of suspended solids on the product; production equipment and production equipment must be regularly inspected. Whether the environmental drainage facilities are intact to prevent products from getting damp; formulate production operation specifications and strictly implement regular and irregular cleaning systems.

  
  

  2.2.2 During the product storage process, the temperature and humidity of the warehouse need to be reasonably monitored and equipped with a good ventilation and drying system. If the warehouse will be affected by the structure and layout, the ventilation capacity is limited, and the moisture is difficult to dissipate, ventilation facilities should be added or even Place a reasonable desiccant to absorb moisture and reduce humidity.

  
  

  2.2.3 Disinfection of warehouse

  (1) Ultraviolet disinfection (currently the most cost-effective, environmentally friendly and safe disinfection method)

  a Control the warehouse temperature below 30°C (optimal);

  b Control the relative humidity below 65%;

  c The installed ultraviolet lamp needs to be selected according to needs to achieve the purpose of penetrating the air layer, drying the air, and inhibiting the reproduction of mold.

  d. Ultraviolet exposure: It is recommended to use ultraviolet lamps with a 185nm spectrum line (commonly known as the ozone spectrum line), which are evenly distributed on the warehouse ceiling (one every 5m). From March to July, they are turned on twice a day at night, 1.5 times each time. -2h. Usually turn it on twice a day at night, 30 minutes each time

  e. Ultraviolet rays are only suitable for sterilizing the surface of materials or the air. The penetrating power is weak. It is difficult to penetrate opaque materials or thin glass, and there will be many blind spots that cannot be irradiated.

  
  

  (2) Antifungal agents kill mold

  When anti-mold and antibacterial agents come into contact with microorganisms such as mold, they are adsorbed through positive and negative charges, enter the protoplasm of the mold through the cell membrane, and are sterilized by destroying the cell structure, affecting metabolism, destroying the nucleic acid structure, and directly piercing the cell wall. This requires Choose non-irritating, low-toxic, and efficient products. Let me advertise here. Our company's disinfectants act on common positive and negative bacteria in 0.5 minutes. The average sterilization rate can reach 99.999%. They act on common fungi in 1 minute. The average sterilization rate can reach 99.999%; it is non-toxic, non-irritating, safe and efficient, and will not cause adverse effects on the product (oxidation, corrosion, etc.).

  
  

  
  

  Operation method: 

  A lot of mold and bacteria will accumulate in the storage of raw material warehouses, and they will be brought into the packaging with the flow of air. When the temperature and humidity are suitable, it is very easy to grow and reproduce in large numbers. It is recommended to disinfect once a month during the Hui Nantian and plum rainy seasons (March to July), and once every two months during the rest of the time. Before holidays or get off work, close all doors and windows, and then use a sprayer filled with antifungal agent to spray the agent into the air of the warehouse. After spraying, the staff will leave and keep it sealed for 24 hours. Open the doors and windows for one hour before going to work, and then choose whether to close the windows according to the indoor and outdoor temperature and humidity (open the windows if the indoor humidity is high, and close the windows if the indoor humidity is high).

  
  

  The specific parameters used are as follows:

  a Use the spraying method, 200cm away from the ground and 60cm away from the window frame, to evenly cover the space in the warehouse in the form of mist-like droplets.

  b Determine the spraying points according to the space area. Generally, 6 points are set for 20㎡. If there are strict requirements, it can be set as 9 points. If it is less than 20㎡, it will be counted as 6 points.

  c Spray each point 3 times in an arc.

  d. Close the doors and windows immediately after spraying to maintain the concentration of anti-fungal ingredients in the warehouse within the effective concentration for 12 hours;

  e Finally, clean the entire warehouse floor with mopping water containing 5% anti-mildew and antibacterial agent.

  f Try not to use it on rainy days to avoid excessive humidity in the warehouse that is difficult to control.

  
  

  2.2.4 Regular inspection of warehouse

  There will also be some raw materials, semi-finished products or finished products that have been stored for a particularly long time in the warehouse. If these goods are stored for a long time, they will inevitably not be corroded by mold. Therefore, we need to conduct regular comprehensive inspections of the finished product warehouse, usually once every 30 days. If necessary, you can check once every 15 days to see if there are items that are not arranged neatly, whether there is dust on the materials, whether there are spider threads on the ceiling, whether there is mildew on the walls, etc. Once found, deal with it immediately (clean and scrap it) , mildew removal, mildew prevention). The inventory time of particularly long (more than 60 days) and high-risk moldy raw materials (natural materials) have become the focus of inspection.

  
  

  
  

  
  

  The above plan is formulated based on the actual mold risk of your company's products. Strictly following this plan will completely solve your company's mold problem. It can completely protect your company's products from mold.
