The unique benefits of solar insect killer lamps
The structure of this type of mould is relatively complex, making it difficult to remove some plastic parts such as caps and closures with detailed threads using standard knock-off methods. After the parts are moulded, they need to be carefully unscrewed from the mould to avoid damaging the threads. With over 15 years of experience in unscrewing moulding, we specialize in Inside Unscrewing Mould, Outside unscrewing mould, and unscrewing mould inside and outside. Therefore, we can design excellent unscrewing moulds to produce various unscrewing products. According to the types of different unscrewing products, we will choose two different demoulding methods: the first one is to use the elastic deformation of the material to forcibly eject the plastic part from the core through the unloading plate when the material allows, which is called Forced demoulding method. The other type is for plastic parts with deeper unscrewing, higher material strength, and higher thread accuracy requirements. We will use the rotational demoulding method. unscrewing injection mold design,auto unscrewing mould,unscrewing injection mould,injection mold unscrewing,Unscrewing Moulds Dongguan Hongke Plastic Precision Mould Co.,Limited , https://www.scientificmolds.com
Nowadays under the background of the country’s strong support for renewable energy and the rapid development of solar energy, new types of solar insect killer lamps have been widely used. Solar insecticidal lamps use solar photovoltaic modules to convert solar energy into electricity during the day and store them in maintenance-free storage batteries. At night, the control system automatically turns on the high-voltage power grid and LED light sources according to the light illumination. The ultraviolet radiation emitted by the LED lamp generates a phototaxis effect on the insects, which induces the insects to pounce on the LED light source. The LED light source is configured with a high-pressure killing net to kill the pests when the pests plunge into the light source, thereby achieving the purpose of killing pests.
At present, most of the wavelengths of the light emitted by the LED lamps used in the solar-powered insecticidal lamps on the market are the wavelengths of ultraviolet light of a special wavelength of 365±50 nm for pest trapping. In Ding Yanqin’s behavioral selection experiment of 13 monochromatic lights on Helicoverpa armigera, it was found that the peak of the visual acuity curve of Helicoverpa armigera was at 333 nm; whereas the solar insecticidal lamp found in the phototaxis experiment conducted by P. We have a phototaxis response to monochromatic light above 333 nm. From the above findings, we can find that the various phototaxis pests have different visual acuity curves.
Because the energy used by the solar insect killer lamp is quite unique, its advantage is that many power-supply insecticidal lamps cannot reach it, reduce the number of insecticides used, reduce the cost, and make pesticide residues in crops and vegetables in people's lives. Less, this is an important way to protect food safety. At the same time, reducing environmental pollution is undoubted. Maintaining ecological environment and balance is an important significance brought about by solar insect killer lamps.
