1. What color is good for Shading nets?

There are many colors of Shading nets, such as black, white, green, blue, yellow, red, silver -gray, etc. So, what color is good for Shading nets?

The color of the Shading net is added in the process of making raw materials. At present, the shade net sold on the market is mainly black and silver -gray. The Shading net color should be selected according to the type of vegetable types.

The black Shading mesh is high and the cooling rate is fast, but it has a greater impact on photosynthesis. It is more suitable for use on leafy vegetables. If used on some happy vegetables, the coverage time should be reduced;It has a small impact on photosynthesis and is suitable for eloquent vegetables such as eggplant fruits.

2. Why is the Shading net black

Black Shading net is a very suitable Shading Tool for vegetables that need light. This is because black is weaker than any color reflecting Solar light, that is, the ability to absorb sunlight is the strongest.When the sunlight transversed from the Shading net, the energy (thermal energy) of the Solar light has been consumed, and the following is naturally cool.So it is very suitable for the growth of crops.What we have seen on the market currentlyShading netMost of them have two colors, one is black and the other is gray, and the black effect is also a wider range. The gray ability is not black, so it is generally used on the crops of Xiguang.

1. Which of the Shading effect of aluminum foil Shading net and black net is better

1. Material comparison

Aluminum foil Shading net is a Shading material composed of multi -layer fiber mesh, aluminum foil, and PE anti -ultraviolet material. It has excellent ultraviolet -resistant, shielding, heat insulation and other properties, and has strong durability and compressive resistance.The black net is a Shading material made of HDPE material, which has the advantages of sunscreen, shielding, breathable, etc. Its advantage is that the price is cheaper and has good light transmission performance.

2. Comparison of Shading effect

The aluminum foil Shading net has a good Shading effect. Its special structure allows it to reflect the sunlight of the sun, reduce the direct radiation of the Solar, maintain temperature and increase water evaporation, thereby improving plant yield and growth quality.The anti -ultraviolet effect of this material is also excellent, which can effectively avoid the damage caused by ultraviolet rays to plants.The black net's Shading effect is slightly inferior to the aluminum foil Shading net, but for some occasions that need light transmission, the black net is a more suitable choice than the aluminum foil Shading net.

3. Select suggestions

When choosing a Shading material, we must first consider the application scenario. If the material is required to have anti -ultraviolet rays and Shading effects, it is recommended to choose an aluminum foil Shading net; if the material is better, you can choose the black net.In addition, the price of aluminum foil Shading net is relatively high. If the requirements are not high and the price is low, you can choose the black net, but you should pay attention to the quality of the material to avoid waste from buying inferior materials.

In summary, the aluminum foil Shading nets and black nets have their own advantages and disadvantages, and appropriate materials need to be selected according to actual needs.When purchasing, you should try to choose materials with quality and guarantee. Do not choose inferior products for cheap or other reasons, causing unnecessary economic losses.

2. How to distinguish the quality of the shade net

1. Material

The inferior Shading net is made of recycling materials (old materials, flower materials) and inferior colors, and the ultraviolet absorbers and antioxidants are not added.

2. Appearance

The high -quality Shading mesh surface is flat, Smooth, shiny, uniform and clear with latitude and weft. In the sun, the color is black and black, the color is small, and the silk has no overlap.

The inferior Shading mesh surface is uneven, no gloss, no light, uneven latitude and weft, with gray black in the sun, large color difference, the silk mesh contains impurities, and the silk mesh overlap.

3, feel

High -quality Shading net feels soft, not rough, not stiff, and elastic.

The inferior Shading net has a rough feel, a bit stabbing, feels thick, and non -elastic.

4. Smell

The high -quality Shading net has no odor, and some are just a faint plastic scorching flavor.

The inferior Shading net is unpleasant, pungent, and plastic scorched flavor.

5. Quality

High -quality Shading nets have a Square gram of heavy gram, and the width and length are accurate. There are no holes in the mesh surface, no filament, strong single silk elasticity, and strong tensile ability.

The Square gram of the inferior Shading net is not standard, the width length is inaccurate, the mesh is hole, the silk is severe, and the single silk has no elasticity and no tensile force.

6. Life life

High -quality Shading nets have been used for more than 3 years under natural climatic conditions (excluding membrane, sulfur corrosion and polymeter areas).

The inferior Shading net is less than 1 year under natural climate conditions.

7. Economy

The high -quality Shading net is generally calculated according to the Square number, and the surface price is high.However, due to the light weight of the mesh, the actual length is accurate, the area is large, and the service life is long. It is much more affordable to calculate according to the service life of peace.

The inferior Shading net is generally calculated according to weight, and the surface price is low.However, due to the weight of the webbage, the actual length is insufficient, the use area is small, the service life is short, the labor cost is high, the cost of the shed is high, and it is not affordable.

1. What kind of sunshade mesh and web needle is more solid

The flat needle Shading net has a closer structure, smaller acupuncture pitch, stronger and durable, longer service life, good toughness, not easy to break, and strong wear resistance.The network needle is resistant to corrosion, which can be used in humidity, and at the same time, ventilation is better.Therefore, the specific choice of the Shading net should be selected according to the environment and requirements.

2. Which sunscreen mesh and oblique needle is durable

The durability of the oblique needle.The Shading net with the same material and needle is better to choose a diagonal needle.Because the oblique needle is more firmly woven, it is not easy to occur during use and damage.Relatively speaking, the durability of the flat needle is not strong, so it is recommended to choose the oblique needle when choosing a Shading net.The oblique needle's Shading net has a good effect on disaster relief and income. During the use process, it must be straightened, tightened, and flattened. There must be no low places. Otherwise, it is prone to stagnant water falls on rainy days, causing the net to be damaged.

3. precautions for Shopping.com

1. When buying a Shading net, many people are very easy to buy a net with a high shielding rate, which is mistaken for the high shielding rate.However, too high shielding rate causes weak light in the shed, reduced photosynthesis of crops, weak stems, and long -term problems, which reduces the production of crops.So try to choose the Shading rate as low as possible when choosing a Shading net.

2. When buying a Shading net, try to choose a guarantee product with big manufacturers and brands, and determine the use of products that have been used for more than 5 years on the greenhouse.

3. The thermal contraction characteristics of the shade net are easily ignored. The most contracted in the first year, about 5%, and gradually become small.With its contraction, the shielding rate will increase.Therefore, it is necessary to consider its thermal contraction characteristics when using a card slot.

1. What does it mean?

The Shading net is divided into scriptures and weft, and the edited Shading net is divided into several needles according to the different weaving needle distance.How many shots of the Shading net refer to the number of pins in each inch. The more the number of pins, the dense the network.Depending on the number of needles, the Shading net can be divided into one shot Shading net, two -needle Shading nets, three -needle Shading nets, and more pins.Of course, due to the difference in the number of Shading mesh pins, the fields and environments they are used will be different.
