Agricultural film simple preservation method

Agricultural plastic film is not well kept, it is easy to harden aging, affect the service life. The correct way to save is:

The bag storage method will be used to clean the plastic film with a plastic bag, tie the bag mouth, and keep it in a cool place.

The water storage method will immerse the washed agricultural film in the water tank (pool), cover it with shade, and pay attention to the lack of water during storage, otherwise it will be more susceptible to aging.

The burial method buries the washed agricultural film with water in moist loess, and it is necessary to keep the soil moist during storage.

The pit storage method will level the washed agricultural film and put it into a damp crypt, which can delay the aging of the film.

What is Fractional Co2 Laser
Fractional CO2 Laser generate beams of coherent light that are absorbed by the body's tissue as energy. The energy is delivered through a narrow range of wavelengths, and in the target area, the energy 
causes temperature elevation which results in tissue evaporation or ablation. Fractional CO2 Laser effectively treat a broad range of skin conditions by removing all or part of the skin. 
The body's natural healing processes then replace the damaged skin with new and healthy tissue. 

How Does A Fractional CO2 Laser Work?
Fractional CO2 Laser produce light at a 10,600nm wavelength, which is absorbed by water in the tissue. The laser energy heats up the water until it reaches a boiling point causing the evaporation of the affected tissue. Some heat is absorbed by tissue adjacent to the ablated target area, causing tissue coagulation which induces hemostasis (the cessation of bleeding) as well as thermal stimulation of deep skin layers, which induces fibroblast stimulation and neocollagenesis (the formation of new collagen).
The laser beam can also be transmitted through a scanner which is a device used to further control the delivery of energy.  The scanner regulates the configuration of energy delivered onto the skin, which can range from covering the entire treatment area or just a fraction of it (leaving the areas in between untreated); (also referred to as fractional ablation). The overall effect of ablation and coagulation, either full or fractional, is the removal of skin and the stimulation of the body to replace it with newer, younger skin.
