  The main purpose of the  Dust-Proof Brush  is to install it at the inlet and outlet of industrial equipment, assembly lines, doors and windows, etc., to prevent dust from getting in through these gaps and contaminating equipment and products, so the requirement for brush wire is to have high elasticity, The surface of the brush wire is well lubricated, preferably with antistatic function. The polishing  Brush  is mainly used to deburr and finely polish the surface of the parabolic object, so the type and characteristics of the brush wire should be determined according to different requirements. If it is a steel plate with strong hardness, the surface should be electroplated and polished. The most ideal brush wire should be bronze wire. If it is a general metal material for surface derusting and deburring treatment, a steel wire with better hardness can be used; The cleaning  Brush  is the most commonly used industrial wheel brush. It is generally use...

  Abstract: With the rapid development of modern warfare  Low-Altitude Penetration Weapons  and the gradual opening of my country's low-altitude airspace, civil air defense has put forward an urgent need for low-altitude and ultra-low-altitude early warning capabilities. The low-altitude early warning radar uses advanced  Phased Array Technology  to control the beam of distributed T/R components to achieve elevation scanning, and improves measurement accuracy through vertical multi-wave position scanning and intra-wave position and difference beam angle measurement capabilities. The system adopts the wave position allocation method of 8 elevation beams. In order to ensure sufficient pulse accumulation, the low beam is processed by MTD of three groups of 6-pulse filters, and the high beam is processed by 3-pulse MTI. In terms of processing algorithm, we adopt the design and algorithm of high clutter improvement factor, use clutter map and various threshold detect...

The reason why r eflective Materials  can reflect light is that most reflective materials contain a kind of high-refractive index glass beads. It is precisely because of its existence that it reflects the human light back to the light source according to the original path, forming a phenomenon of retroreflection. The main  Products  are all kinds of reflective films, and the reflective materials used on highways belong to this type. At present, the application of reflective materials is mainly concentrated in two major market areas, one is the planned special market, and the other is the civilian market. The planned special market has formed a considerable scale, and the civilian market has huge potential, which is optimistic about the reflective material industry giants such as the American 3M Company, the pioneer of the world's reflective materials. The so-called special market for planning generally refers to the fields in which reflective materials must be used accord...

  How to use  Peppermint Essence Fragrance  is a concentrated aromatic oil that is synthesized by imitating the smell of fruits and natural spices. It is an artificial fragrance. It is mostly used in the manufacture of food, cosmetics and cigarettes. The first flavor synthesized by humans was vanillin, which was successfully synthesized in 1874 by Dr. Vanillin is the main ingredient in the natural flavor of vanillin beans. Two years later, another chemist, K. Reimer, was also involved in vanillin research. The synthetic vanillin he synthesized was almost indistinguishable from the natural vanillin. Chocolate manufacturers in Germany were the first to use artificial vanillin, and soon after, confectioneries in London began to make hard candy from fruit gum. Today, various fruit and fish flavors can be synthesized chemically. What is the use of peppermint essence? Peppermint essence is mainly to supplement the lack of original aroma in products. It stabilizes and assists th...

  Herbicides , as the name suggests, are agents that destroy or inhibit plant growth. The use of herbicides in agricultural production has a history of many years. The current mainstream  Herbicides  are mainly divided into biocidal and selective herbicides according to their functions. Biocide herbicides simply means killing all crops regardless of the crop, mainly used before sowing;       selective herbicides are made in a targeted manner according to the different resistance levels of different types of seedlings, and can theoretically kill weeds. Grass, which is harmless to seedlings, is actually not perfect for many reasons. Today, Xiaobian brings you an introduction to the types and characteristics of commonly used  Herbicides . Sulfonylureas 1. High activity, measured in grams per hectare. 2. The weeding spectrum is wide, and the weeding spectrum of different varieties is very different. 3. Strong selectivity, high safety to crops, and high eff...

 Features of Reflective Materials Reflective material is a high-tech product widely used in traffic safety equipment, uniforms, work clothes, film, protective cloth and other fields. Reflectivity: The reflective brightness of reflective materials is very good. For example, the reflective intensity of silver-gray series products is typically 500CPL, and the reflective intensity of white and fluorescent yellow reflective plastic films is typically 700CPL, which can provide the highest reflective intensity at night or in environments with poor visibility. Effective and most reliable personal security. Wide-angle: The reflective material is not only better than similar products of other brands in the reflective effect, but also has a wide-angle, that is, when the light enters from a large angle to the surface of the reflective material, it can still obtain a good reflective effect. Diversity: Reflective materials are available to match the characteristics and uses of various other...
