Anti - fog films have gained unanimous recognition for their good light - transmittance performance. Their use effectively extends the service life of greenhouse films, thus saving agricultural costs.

Pay attention to the following issues during the daily use of anti - fog films.

Firstly, multi - layer co - extruded films have an arc - shaped surface, and the inner, middle, and outer layers have different functions of anti - fogging and dripping, heat - insulation, and anti - aging. When covering the greenhouse, be sure to pay attention to the instructions and do not cover the film upside down.

Secondly, in terms of storage, after purchase, place the film in a cool and dry environment, avoid humidity and exposure to the sun, and pay attention to the shelf life.

Thirdly, maintain an appropriate humidity inside the greenhouse, because the moisture in the greenhouse will affect the function of the anti - fog film. Therefore, it is necessary to maintain an appropriate humidity inside the greenhouse and carry out ventilation.

Fourthly, regarding temperature, try to avoid high temperatures as much as possible, as high temperatures can cause fogging inside the greenhouse, greatly affecting the light transmittance of the film.

The characteristics of anti - fog film products:
1. It heats up quickly and has good heat - insulation performance. The heating speed, heat - insulation performance, and optical performance are significantly better than those of double anti - dripping films.
2. The light transmittance is above 95%, and the anti - aging period can last up to 12 - 24 months.
3. It has strong puncture resistance and high tensile strength. The excellent tensile strength effectively improves the wind resistance of agricultural films.
4. The anti - fogging and anti - dripping performance of the anti - fog film lasts for a long time, and there will be no fog throughout its service life.
5. It has good flexibility. Good softness can improve the shrinkage rate of the greenhouse film and reduce the damage to the film after rain and snow.
6. It has strong disease resistance, which can effectively reduce the reproduction of pathogens and pests in the greenhouse, reduce the occurrence of diseases and pests, and has a high resistance to viral diseases caused by temperature.

The usage methods of anti - fog films:
1. When covering the greenhouse, do it correctly from the outside of the greenhouse. Do not cover the film with the existing liquid - coated side facing down. After covering, it is strictly prohibited to leave downward - facing ventilation holes. Seal the greenhouse after the anti - fogging liquid droplets have dried completely, because sealing the greenhouse before the anti - fogging liquid droplets dry will cause the anti - fogging liquid droplets to fail. This is related to the success or failure of the dripping effect of the greenhouse film.
2. From October of the Gregorian calendar to the freezing period, the ventilation time should be longer, 1 - 2 days on sunny days and 2 - 3 days on cloudy days.
3. To avoid affecting the dripping effect, avoid artificial wrinkles when covering the greenhouse.
