Three years of cold cloth? This is the right way to extend the service life of the cold cloth

Recently, the weather has turned cold. I believe that many fruit farmers have used the old farmer's wish cold cloth to keep fruit trees fresh. Although the old farmer's wish cold cloth can not age under 3000 hours of sunshine, it is always good to maintain the cold cloth to extend its service life. How to extend the service life of the cold cloth? Cold-proof cloth is a kind of non-woven fabric, also called non-woven fabric. It is an emerging material. It is a combination of oriented or randomly arranged fibers combined by various methods (such as bonding). The soft, light, breathable, and flat-structure new fiber structure products also have the characteristics of short process flow, high production efficiency, significant economic benefits, rich product varieties, and wide application ranges. They have become an emerging industry in China's textile industry. industry. The fiber raw material used for non-woven fabrics can be natural fibers such as cotton or materials such as PP or polyester fibers, and has been used on a large scale in plantations in Guangxi, Sichuan and other places. Like other chemical materials, under the conditions of light and heat, cold cloth will also experience aging, and the reason for the aging of cold cloth is mainly the result of the combined effect of internal and external factors. Internal factors include the chemical composition, molecular weight distribution and organizational structure of the material itself. External causes usually refer to the influencing factors in the external environment where the material is located, including: (1) physical factors, such as mechanical stress, heat, water, light, etc.; (2) chemical factors, such as corrosive gas or liquid, (3) such as Microorganisms, bacteria, molds, insects and other factors. Among them, photo-aging and photo-degradation. After understanding the above factors that affect the service life of cold cloth, we know that the material structure of cold cloth cannot be changed, but light and heat will affect the main reason for the service life of cold cloth. As long as we pay attention to the following points, we can extend the service life of the cold cloth. 1. After the cold cloth is used up, it should be collected in time to avoid prolonged exposure to the sun. 2. When collecting the cold cloth, avoid scratching the branches. 3. Avoid collecting cold-proof cloth in rainy or dewy weather. If there are water droplets, wipe it dry and put it away. 4. Avoid splashing pesticides or other chemicals on the cold cloth. 5. After recycling the cold-proof cloth, avoid exposing it to the sun to avoid getting wet. It should be stored in a cool place. 6. Avoid storing cold-proof cloth in the same place with pesticides or fertilizers. If there is no place to put them, please separate the cold cloth from the pesticides and fertilizers. The cold-proof cloth should be covered with black material to avoid exposure to light. The above is the method to extend the service life of the cold-proof cloth. The old farmer's wish cold-proof cloth is made of polymer materials, with a 5-layer process, and it can be measured without aging under 3000 hours. If you need it, you may wish to try the old farmer's wish cold cloth.
