Effect of Nanopowder on Agricultural Expelling Insect

Nanomaterials have broad application potential in insect repellent agriculture. The following are some common examples of nano powders that may play a role in agricultural pest control:

 

  1. Silica nanoparticles(HW-A213): Silica nanoparticles are widely used in agriculture as an environmentally friendly pesticide. They can adsorb on the surface of insect shells, damage the protective layer of the insect body, and cause dehydration, suffocation, or death of the insect.

 

  1. Metal oxide nano powder: metal oxide nano powder, such as silicon dioxide (HW-T681&T689) and zinc dioxide (HW-Z713), has the effect of insecticide. They can kill insects by photocatalysis, activate the surface of nano powder by ultraviolet radiation, produce free radicals or oxides, and cause damage to insects.

 

  1. Carbon nanotubes(HW-C931): Carbon nanotubes have a large surface area and high mechanical strength. They can be used as carriers to load insecticides onto their surfaces and improve insecticidal efficacy by controlling release. In addition, carbon nanotubes can also be used as insect sensors to monitor and control pests by detecting chemical signals released by insects.

 

  1. Nano boron nitride(HW-L551): Nano boron nitride has excellent thermal conductivity and stability, and can be used to develop efficient fire-resistant materials. In agriculture, it can also be used as an insecticide to control pests through physical effects or interference with the normal physiological activities of insects.

 

  1. Nanographene(HW-C952): Nanographene is a nanomaterial with excellent conductivity and photothermal properties. It can be applied to the electric insecticidal mechanism, which kills pests by heating. Nanographene can generate high temperatures at lower currents, causing fatal damage to agricultural pests.

 

The application of nano powder in agricultural insecticide is mainly reflected in the use of nano pesticide. Nanopesticides are the use of nanotechnology to prepare pesticide active ingredients into nanoscale particles, in order to enhance their solubility, dispersibility, and activity, improve the effectiveness and utilization of pesticides, and ensure their safety and environmental friendliness. In addition, scientific and reasonable agricultural management and the application of comprehensive prevention and control measures remain the key to promoting sustainable agricultural development.

Nano Materials applied in flexible screens

The beauty of flexibility is everywhere. The development of flexible screens can be applied to all walks of life, make life more concise and convenient. Here are some nano materials that can be used for flexible screens:

ITO nanopowder

ITO (tin oxidation) transparent conductive film has become the most important touch layer material for display screens such as non -curved LCD and OLED due to many reasons such as good light transmission, low thickness, excellent hardness and electrical conductivity, and mature production process. However, ITO is a kind of crispy material, not suitable for the flexible touch layer that can be curved or even bent at will, and the cost is high.

Nano graphene, carbon nanotubes, silver nanowires, etc.

At present, the main substitutes for ITO materials are: nano graphene, carbon nanotubes, silver nano wires, and metal grids. Among them, nano graphene and carbon nanotubes are very good substitutes for ITO in terms of material itself. But graphene is still a bit far from mass production. The film made of nano -carbon tube is not as good as ITO in conductivity. Therefore, from the perspective of technology and market, metal grids and nano -silver technology will be the protagonist of recent development.

The metal grid technology mentioned here is the conductive metal mesh formed by using metal conductive materials such as silver and copper or oxides on PET and other thin film substrates. Its main advantage is that the cost of raw materials is low and good for winding. However, due to the problem of Morri interference ripples caused by good rate, yield and high -end high pixels, it is more suitable for applications with low resolution and relatively long -distance use. Desktop all -in -one machines, laptops and television products.

Nano -silver wire technology refers to applying nano -silver wire ink materials to PET or glass substrates, and then uses Laser lithography technology to portray the nano -level conductive network. Its main advantages are high rates, small line width, good conductivity and resistance, and disadvantages are high costs. And compared to metal grids, nano -silver materials have a small curvature radius, and the resistance changing rate of resistance during bending is small, plus the reasons for the width, so it is more suitable for high -resolution such as mobile phones, smart watches and bracelets. Use in close range scenes.

The Nano Powders for Preparing Special Ceramics

Special ceramics refer to ceramic materials with special properties and specific applications. Compared with traditional ceramics, special ceramics have higher hardness, wear resistance, high temperature resistance, corrosion resistance, and insulation performance, and are widely used in various fields, including aerospace, electronics, medical, energy, chemical, etc.

 

Nano powder can play an important role in the preparation of special ceramics. By adding nano powders to the raw materials of special ceramics, the microstructure control and performance optimization of materials can be achieved. Nano powder has large specific surface area and size effect, which can enhance the mechanical properties, thermal conductivity, optical properties of special ceramics, and improve the processing properties and density of materials.

 

The following are several nano powders commonly used to prepare special ceramics:

 

Nano zirconia powder (HW-U702): With excellent mechanical properties, wear resistance, and chemical stability, it is suitable for preparing wear-resistant and corrosion-resistant special ceramics, such as cutting tools and ceramic coatings.

 

Nano alumina powder (HW-N611): With high hardness, heat resistance, and chemical stability, it can be used to prepare high-temperature ceramic materials, such as ceramic aviation engine components and high-temperature resistant electronic devices.

 

Nano tin oxide powder (HW-X678): With good conductivity and optical properties, it can be used to prepare transparent conductive ceramic materials, such as touch screens, displays, and solar cells.

 

Nano tungsten oxide powder (HW-W691): With high density, high melting point, and excellent wear resistance, it is suitable for preparing high-temperature and wear-resistant ceramic materials, such as cutting tools, bearings, and valve guides.

 

These special ceramic materials have extensive applications in many fields, including electronics, medical, aerospace, energy, and automotive industries. Their unique performance makes them suitable for various extreme environments and applications that require high durability.
