High-temperature invincible performance evaluation device of agricultural film

摘要

Under the condition of high temperature in this case, there is no performance (actual) evaluable equipment for agricultural film.Agricultural film is mainly used for trial use in plastic shed construction,The temperature of the house and the atmosphere,Moisture tea condenses on the inner surface of the film, dew or small water drops, thus accumulating water every dayFalling, damage to cultivated crops, cold damage, etc,In particular, the falling water droplets make the growing atmosphere of crops wet, leading to various diseases and insect pests such as mycosis.Therefore, in order to reduce the phenomenon of water dripping, the film with military enemy performance has been developed, and the invincible performance of this film can not be measured. Up to now, it can directly avoid in the plastic shed, according to the seasonal and diurnal temperature changes. This is not only a long-term need on the tester, but also the setup cost and excessive need of the site.In this case, a small evaluation device is used to arbitrarily assign high temperature conditions, which can be used to measure the high temperature performance of the evaluation object film in a short time, so as to evaluate.
