The sunshade net is a new type of protective covering material for agriculture, fishery, animal husbandry, windproof and cover soil that has been promoted in the past 10 years. After covering in the summer, it plays a role of blocking light, preventing rain, keeping warm and cooling. After winter and spring coverage, there is still a certain degree of heat preservation and humidification.
According to the density, the shade nets are divided into two needle shade nets,three needle shade nets, four needle shade nets, and six needle shade nets.
The shading rate is calculated according to the opening ratio. To be precise, the angle of each triangular hole is used to calculate the area of the opening. For example, the opening ratio is 10%, and the shading rate is 90%.
Generally, the shading rate of the two needles is 10%-50%, the shading rate of the three needles is 40%-80%, the shading rate of the four needles is 50%-90%, and the shading rate of the six needles is 70%-95%.
