How to use the cold cloth for more than 3 years? You will be there after watching

Citrus was affected by the weather in the first half of last year. The introduction of frozen fruits to the market was dragged down. Rainy and overcapacity caused the slow sales of citrus. Therefore, it is very important for citrus to be listed on a staggered peak. Keep fresh and keep out the cold, so last year not only did not lose money, but also made a lot of money. But do we know how to extend the use time of the old farmer's wish cold cloth? Here is an introduction to those factors that will affect the life of cold-proof cloth, and what measures we should take to preserve it. The old farmer's wish cold-proof cloth is a kind of material for cold-proof and warm-keeping of crops in agriculture. It is a kind of non-woven fabric. The old farmer’s wish for citrus cold-proof cloth non-woven fabric (Nonfabric), also known as non-woven fabric or non-woven fabric, is an emerging material. It is composed of oriented or randomly arranged fibers combined by bonding and other different methods. It is soft, The new type of fiber structure products with light weight, air permeability and flat structure also have the characteristics of short process flow, high production efficiency, significant economic benefits, rich product variety and wide application range, and have become an emerging industry in China's textile industry. The fiber raw materials used for non-woven fabrics can be natural fibers such as cotton and materials such as PP and polyester fibers, and they have been used in large-scale plantations abroad. The old farmer wishes to use real shots for cold-proof cloth. Non-proof cloth has a good microclimate regulation function, can heat and keep warm. It can not only improve the environment and growth conditions, but also play a protective role. Non-woven fabrics are used in agricultural production at home and abroad The field is widely used as agricultural covering materials, plant growth substrate materials, greenhouse materials and farmland water and soil protection materials, and has achieved remarkable results. Although its weight is lighter, it has good mechanical properties, and its toughness and strength are relatively high. High, it can be used repeatedly, which undoubtedly greatly reduces the amount of non-woven fabric used, and its easy recycling feature makes it more environmentally friendly. Old farmers wish that citrus cold-proof cloth is the same as other chemical materials. Under the conditions of light and heat, cold-proof cloth will also age. The reason for the aging of cold-proof cloth is mainly the result of the combined effect of internal and external factors. The internal factors include the chemical composition, molecular weight distribution, organization structure and other factors of the material itself. The external factors 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 gases or liquids, etc. (3) biological factors Factors such as microorganisms, bacteria, molds, insects, etc. Among them, photo-aging and photo-degradation (as shown in Figure 1) are one of the most important problems encountered in practical applications of cold-proof fabrics. Knowing the above factors that affect the life of cold-proof cloth, we know that the material structure of cold-proof cloth cannot be changed, but light and heat affect the main reason for the life of cold-proof cloth. As long as we work properly, we can extend the service life of cold-proof cloth. . 1. After the cold-proof cloth is used up, it should be put away in time to avoid exposing it to the sun for a long time in the open air. 2. When collecting the cold-proof cloth, try to avoid cutting the branches with cold-proof as much as possible. 3. Don't collect the cold-proof cloth in rainy or dew days. You can collect the cloth after the dew is gone, or if there is water droplets when collecting the cloth, it should be dried and then put away. 4. Avoid splashing pesticides or other chemicals on the cold-proof cloth. 5. After the cold-proof cloth is recycled, it should be avoided to expose it to the sun to avoid exposure to water. 6. After the cold-proof cloth is recycled, it should be stored in a cool and dark place. 7. Avoid storing cold-proof cloth and pesticides or fertilizers in the same place. If there is no place to put them together, separate the cold-proof cloth from pesticides or fertilizers. It is best to cover the cold-proof cloth with black material to avoid exposure to light.
