Selection of internal/external sunshade net

Selection of internal/external sunshade net

In summer, the sunshade net plays a role in blocking light, rain, moisture, and cooling. In winter and spring, there is a certain effect of heat preservation and humidification after covering the sunshade net. The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled material, new material, and polyethylene-propylene as raw materials, after UV stabilizer and anti-oxidation treatment, with strong tensile resistance, aging resistance, corrosion resistance, radiation resistance, light, and other characteristics. It is mainly used in the conservation cultivation of vegetables, incense buds, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum, and other crops and the aquaculture and poultry industry, and has an obvious effect on increasing the yield.

Now on the market, the quality of the sunshade net is uneven, some of the sunshade net service life is only about a year, is commonly known as the flat screen, the sunshade net service life is short, low shading rate is not suitable for application in the greenhouse. The sunshade net used in the greenhouse is generally a round wire sunshade net, which has a high sunshade rate, usually 75%, but some can reach 90%.

The internal/external sunshade net needs to meet the requirements of long service life and high sunshade rate, and even the internal sunshade net needs to achieve a certain insulation effect. Application in the greenhouse, it is recommended that you choose a good quality external sunshade net. With the following principles I wish you a choice of excellent quality greenhouse shade net:

1. The net surface is flat and smooth, the flat wire is parallel to the gap, neat and uniform, and the longitude and weft are clear and bright.

2. Regular size packaging, shading rate, specification, and size clearly marked.

3. No peculiar smell, foul smell, some only plastic light burnt smell.

4. Good finish, quality, and brightness, deep black brightness, rather than the feeling of floating surface brightness.

5. Moderate flexibility, flexibility, no stiffness, not rough, smooth space thick texture.
