防寒布是一种保护农作物免受农业冷热影响的材料。但是，我们知道如何延长防寒布的使用时间吗？在这里向您逐一介绍这些会影响防寒布寿命的因素，我们可以采取措施增加防寒布使用时常以节省开支。
Cold resistant cloth is a material used to protect crops from the cold and hot effects of agriculture. But do we know how to extend the use time of cold resistant fabrics? Here we will introduce to you one by one the factors that will affect the lifespan of cold resistant fabrics. We can take measures to increase the frequency of use of cold resistant fabrics to save costs.
像其他化学材料一样，在光和热的条件下，防寒布也会出现老化现象，而防寒布的老化原因则主要是内部和外部因素综合作用的结果。内部因素包括材料本身的化学组成，分子量分布和组织结构。
Like other chemical materials, cold resistant fabrics can also experience aging under light and heat conditions, and the aging of cold resistant fabrics is mainly the result of a combination of internal and external factors. Internal factors include the chemical composition, molecular weight distribution, and organizational structure of the material itself.
外部原因通常是指材料所在外部环境中的影响因素，
External factors usually refer to the influencing factors in the external environment where the material is located,
包括：
Including:
（1）物理因素，例如机械应力，热量，水，光等；
(1) Physical factors, such as mechanical stress, heat, water, light, etc;
（2）化学因素，例如腐蚀性气体或液体，
(2) Chemical factors, such as corrosive gases or liquids,
（3）诸如微生物，细菌，霉菌，昆虫等因素。其中，光老化和光降解。
(3) Factors such as microorganisms, bacteria, molds, insects, etc. Among them, photoaging and photodegradation.
了解了影响冷布使用寿命的上述因素后，我们知道冷布的材料结构无法改变，但是光和热会影响冷布使用寿命的主要原因。只要我们工作，我们就可以延长冷布的使用寿命。 。
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 are the main reasons that affect the service life of cold cloth. As long as we work, we can extend the service life of cold cloth.
1.防寒布用完后，应及时收集，以免长时间暴露在阳光下。
1. After using the cold resistant cloth, it should be collected in a timely manner to avoid prolonged exposure to sunlight.
2．收取防寒布时，要避免使树枝刮破。
2. When collecting cold resistant cloth, avoid scratching the branches.
3.避免在雨天或露水天收防寒布定送水  铜鼎铜钟 化粪池钢模具 保定代理记账 保定道闸 电缆接地箱，如果有水滴，应将其擦干再收起来。
3. Avoid collecting cold resistant cloth on rainy or dewy days. If there are water droplets, they should be wiped dry before being collected.
4.避免将农药或其他化学药品溅在防寒布上。
4. Avoid splashing pesticides or other chemicals on the cold resistant cloth.
5.回收防寒布后，应避免将其暴露在阳光下，以免沾水。应将其存放在阴凉处。
5. After recycling the cold resistant cloth, it should be avoided from being exposed to sunlight to avoid getting wet. It should be stored in a cool place.
6.避免将防寒布与农药或化肥存放在同一地方。如果没有放置它们的地方，请将防寒布与农药化肥分开。防寒布应覆盖黑色材料，以免见光。
6. Avoid storing cold resistant cloth in the same place as pesticides or fertilizers. If there is no place to place them, please separate the cold resistant cloth from the pesticides and fertilizers. Cold resistant cloth should be covered with black material to avoid light exposure.
