How many mesh of insect net is generally appropriate, which of 40 mesh and 60 mesh of insect net is

Generally speaking, 40-60 mesh insect nets can basically play a role in preventing aphids.

effect, but also conducive to ventilation.

The main mesh of the insect-proof net is 40 mesh, 60 mesh, 80 mesh, and 100 mesh, and the larger the number of meshes, the denser the insect-proof net. The influence of insect nets with large mesh on the temperature and humidity in the greenhouse is greater than that of small mesh.

Insect net is a kind of anti-aging, anti-ultraviolet rays that are added.

Polyethylene and other chemical additives are the main raw materials, and the mesh fabric made by wire drawing has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and tasteless, and easy disposal of waste. Able to prevent common pests such as flies.

mosquitoes, etc. The conventional use of the collection is lightweight, if the use of new materials and correct storage, the life span can reach about 3-5 years.

The choice of insect netting needs to be considered on a case-by-case basis, and here are some general recommendations for choosing an insect net:

If the number of meshes is too small and the mesh is too large, it will not have the desired insect control effect.

If there are too many meshes and the mesh is too small, although it can prevent insects, but the ventilation is poor, resulting in high temperature and too much shading, it is not conducive to crop growth.

For the situation that there are more weeds and more whiteflies outside the shed, it is recommended to use a denser insect net, such as 40 mesh 60 mesh, according to the smaller size of the whitefly to prevent it from entering the hole of the insect net.

In spring and autumn, the temperature is low and the light is weak, so it is advisable to use white insect nets.

Therefore, when choosing an insect net, it is necessary to consider a variety of factors such as the type of crop, growth stage, and climatic conditions. In practical application, it is recommended to choose the right mesh number according to the specific needs to achieve the best insect control effect.

Compared with the 40 mesh and 60 mesh of the insect net, the 60 mesh insect control effect is better.

40 mesh and 60 mesh are the mesh sizes of stainless steel insect nets, in simple terms, the size of the mesh. Among them, the mesh size of 40 mesh is, and the size of 60 mesh is. Therefore, the 60-mesh stainless steel insect-proof net has a smaller pore size, and the protection effect for small insects is better.

For larger insects, such as mosquitoes, flies, etc., the 40-mesh stainless steel insect-proof net can be well screened, but if it is a relatively small insect, the effect of the 40-mesh stainless steel insect-proof net is relatively poor. The 60 mesh stainless steel insect net mesh is smaller, which has the advantage of better protection against small insects, and at the same time, the 60 mesh is relatively thin and difficult to be torn by small animals.

Tips for purchasing insect nets

When choosing, you should consider the number of meshes, color, and width. If the grid is too small and the grid is too large, there is no proper pest control effect; If there are too many grids and the grids are too small, they can be insect proof, but the ventilation is not good, resulting in high temperatures and excessive shading, which is not conducive to crop growth. For example, in the fall, many pests begin to move to sheds before early hail, especially some moths and butterflies.

Due to the large size, vegetable farmers can use insect nets with relatively few meshes, such as 30-60 mesh.

However, for those with a large number of weeds and whiteflies, it is recommended that vegetable farmers use whiteflies in the eyes of insects according to the size of the whiteflies. For example, the key to controlling tomato yellowing leaf curl virus (TY) is to choose qualified insect-resistant nylon gauze. In general, 40 mesh nylon gauze Luqing is enough to prevent whitefly.

It is too dense and poorly ventilated, and it is difficult to cool down in the shed at night after planting. However, at present, the screens produced on the market are rectangular, and the 40-mesh screen can reach more than 30 eyes, and the width is generally only 20 eyes, so only 50-60 mesh screens are used to prevent whitefly.

The 40 mesh and 60 mesh of the insect net means that the particle size or coarseness of the material has reached 40 mesh and 60 mesh. The number of meshes refers to the particle size or thickness of the material, and the general definition refers to the number of mesh holes in the area of 1 foot 1 inch, that is, the number of mesh holes of the screen, and the number of mesh through which the material can pass is defined.

Insect netting is a new type of agricultural mulching material. It is made of high-quality polyethylene as raw material, added with anti-aging, anti-ultraviolet and other chemical additives, and is woven by wire drawing, similar to a window screen, with tensile resistance, water resistance, heat resistance, corrosion resistance, non-toxic and tasteless characteristics, light collection, correct storage life can reach about 3-5 years. Choose the appropriate specifications, the specifications of organic vegetable insect nets include width, pore size, silk diameter, color, etc.

Particular attention should be paid to the aperture size; The mesh is large, and it cannot have the desired insect control effect; If the mesh is small, there is too much shading, which is not good for the growth of crops.

The so-called mesh number refers to the particle size or thickness of the material, and the general definition refers to the number of mesh holes in the area of 1 inch * 1 inch, that is, the number of mesh holes of the screen, and the number of mesh that the material can pass through is defined as how many meshes: such as 200 mesh, that is, the material can pass through the screen with 200 mesh holes within 1 inch and 1 inch. By analogy, the larger the mesh, the finer the particle size of the material, and the smaller the mesh, the larger the particle size of the material.

Mesh size: Standard mesh number: 4 mesh Mesh size:

Standard mesh: 5 mesh Sieve hole size: Standard mesh:

6 mesh mesh size: Standard mesh number: 7 mesh mesh mesh size:

Standard mesh: 8 mesh Mesh Size: Standard mesh 10 mesh Mesh Mesh Size:

Standard mesh: 12 mesh Mesh size: Standard mesh:

14 mesh mesh size: Standard mesh number: 16 mesh mesh mesh size:

Standard mesh: 18 mesh.

The larger the mesh of the insect net, the finer the mesh will be, and the better it is effective in preventing the invasion of pests such as small insects and flower flies. The 40 mesh insect net is more rugged and has better air permeability, while the 60 mesh is more delicate and leaky, which has a better anti-insect effect and can effectively block small insects and flower flies from flying in. Therefore, 40 mesh and 60 mesh insect nets have their own advantages and disadvantages, and the suitable field socks are also different.

If you need a better insect control effect, it is recommended to choose a 60-mesh insect net; If you want better breathability, you can choose a 40-mesh insect net. At the same time, choosing the right insect net according to the actual situation can effectively avoid the attack of pests and bring better protection to home life. 

Dear Hello <>

Glad to answer for you, the number of mesh of the insect net generally refers to the number of mesh per inch of Ying's pin, the larger the number of meshes, the smaller the mesh, so the number of mesh of the insect net is inversely proportional to the size of the mesh. Generally speaking, the choice of insect net depends mainly on which insects or pests need to be prevented, and the size of the mesh needs to be determined according to the size of these pests. For example, a 20-mesh mesh is better for mosquitoes, a 40-mesh mesh is suitable for houseflies and cockroaches, and a 60-mesh mesh is suitable for celery to prevent small flying insects and dust mites.

Therefore, 40 mesh and 60 mesh are more common insect net specifications, and their selection needs to be decided according to actual needs. If you only need to protect against relatively large insects such as cockroaches and houseflies, then 40 mesh insect nets are sufficient; If you need to prevent small flying insects and dust mites, then the 60-mesh insect net will be more suitable. <>
