Description

Anti-UV and light-transmitting heat-insulating insect-proof net

This creation is about anti-insect nets, especially a kind of anti-insect nets that can prevent insects and have dimming.

In order to reduce the risk of pesticide use, the insect-proof net 1 (as shown in Figure 1) has been widely used. The net room built by the insect-proof net 1 is to prevent the invasion of insects and reduce the use of pesticides. Therefore, In the use of functions, the sunlight problem is not included in the scope of consideration. However, the requirements of crops for sunlight are often different due to different crops. This is a problem that is not easy to overcome with the insect screen 1, resulting in actual crops. In terms of planting, in addition to the installation cost of the insect-proof net 1, the farmers sometimes need to set up additional facilities such as lighting to adapt to the individual needs of the crops to be planted in order to reconcile the problem of sunlight.

This will not only increase the cost of setting up the net room, but also add a layer of lighting equipment. If the spacing and distance of the light transmission are not adjusted during the installation, it will not only hinder the air convection in the net room, but also easily Due to the problem of uneven lighting, it directly affects the normal growth and quality of crops.

Based on the above-mentioned deficiencies, the purpose of this creation is to provide an insect-proof net that is both insect-proof and dimmable, so as to improve the growth quality of crops and effectively reduce the cost of installing the net room.

According to the purpose of this creation, an anti-UV and light-transmitting heat-insulating insect-proof net is provided, which has a net body including a plurality of light-transmitting areas and a plurality of light-shielding areas arranged at intervals, and the light-transmitting areas are composed of a The light-transmitting yarn is woven, and the shading area is woven with a color-light yarn.

The light-permeable yarn is made of composite optical fiber, which contains anti-UV powder and light-transmitting heat-insulating powder dispersed in polyethylene fiber, and the anti-UV powder contains at least one of zinc oxide or titanium dioxide Or a combination thereof, the light-transmitting and heat-insulating powder contains tungsten oxide.

When the spectral wavelength range passing through the light-transmitting area is between 240nm and 400nm, the transmittance is less than 20%; when the spectral wavelength range passing through the light-transmitting area is between 400nm and 730nm, the transmittance is 20% To 70%; when the spectral wavelength range passing through the light-transmitting region is between 730nm and 2500nm, the transmittance is less than 60%.

Preferably, the light-transmitting area is a strip-shaped block, the light-shielding area is a strip-shaped block, and the light-transmitting area and the light-shielding area are arranged at intervals.

In order to clearly illustrate the specific implementation, structure, and achieved effects of this creation, examples are provided and illustrated in conjunction with the drawings as follows:

Please refer to Figures 2 and 3, which illustrate a UV-resistant and light-transmitting heat-insulating insect-proof net 2 with a net body including a plurality of light-transmitting areas 21 and a plurality of light-shielding areas 22 arranged at horizontal intervals, the The light-transmitting areas 21 are knitted by a light-transmissive yarn, and the light-shielding areas 22 are knitted by a light-transmitting yarn.

The light-permeable yarn is made of composite optical fiber, which contains anti-UV powder and light-transmitting heat-insulating powder dispersed in polyethylene fiber. The anti-UV powder can be, but not limited to, zinc oxide or titanium dioxide. At least one of or a combination thereof may also be other inorganic materials. Inorganic materials have low toxic and side effects, high chemical stability under high temperature and light conditions, a larger shielding range for ultraviolet rays, can reflect, absorb or scatter ultraviolet rays with a wide range of wavelengths, and have a very low extinction coefficient, which can shield light The net has a good anti-UV effect.

The light-transmitting and heat-insulating powder can be, but not limited to, tungsten oxide. The heat-insulating powder of tungsten oxide has the characteristics of TCO (transparent conducting oxide), because the free electrons are at a specific illuminating wavelength (plasma wavelength) or a larger wavelength. The absorption of infrared rays is formed separately, so it has the effect of shielding infrared rays. And because the size of the particles is much smaller than the wavelength of visible light, the transparency of visible light can be maintained.

Please refer to Figure 4, using the insect-proof net 2 to cover the crops. The sunlight S can penetrate the light-transmitting area of the insect-proof net 2 and irradiate the crops 3, so that the crops can perform photosynthesis, and as the sun moves, the sunlight S will Change the irradiation angle and irradiation position.

Please refer to Figure 5. When sunlight S hits the shading area 22 of the insect screen 2, it will produce different light supplementary effects on the crops, so that the crops can get moderate light fertilizer, and use the intermittent sunlight to adjust the light quality. Insufficiency is the problem of unfavorable crop growth. The shaded yarns of the shading area 22 can be woven with yarns of different shades according to the requirements of the crops 3 days.

Please refer to Figure 6, the aforementioned light-permeable yarn is heat-melt pressed into a thickness of 0.25mm for testing, and the transmittance of light passing through is tested. Ultraviolet light (wavelength is 100nm to 400nm) and visible light (wavelength is 400nm to 730nm) and infrared light (wavelength of 730nm to 2500nm) spectrum transmittance, when the spectral wavelength range through the light transmission area is between 240nm to 400nm, the transmittance is less than 20%; When the spectral wavelength range of the light zone is between 400nm and 730nm, the transmittance is between 20% and 70%; when the spectral wavelength range passing through the light zone is between 730nm and 2500nm, the transmittance is less than 60%.

It is added that the wavelength of ultraviolet light is 100nm to 400nm, but the vacuum ultraviolet light below 200nm will be absorbed by the air, so the wavelength range of ultraviolet C that can pass through the atmosphere is 200nm to 280nm, but this wavelength range will be absorbed by the ozone layer, so generally The measurable ultraviolet light is 240nm to 400nm.

According to the above, the light-shielding zone woven by the aforementioned light-permeable yarn has a penetration rate of less than 20% of ultraviolet light, which can effectively shield ultraviolet light from passing through, so as to prevent plants from being damaged by exposure to ultraviolet light.

Based on the above, this creation system uses the woven structure of the light-transmitting area 21 and the light-shielding area 22, in addition to maintaining the function of preventing pests, it also has a dimming effect, providing intermittent sunlight, and reconciling the lack of sunlight that is harmful to crop growth. It also reduces the cost of installing the net room and increases the convection of the air in the net room.
