Following the major breakthroughs made in carbon fiber composite plastics, NFD researchers have successfully achieved cross-linking polymerization of nanomaterials and engineering plastics, and developed a brand new nanometer superwear-resistant plastic polymer. The new technology can improve the abrasion resistance of plastics by nearly 100 times! This technological breakthrough has great significance, so that China's high wear resistant plastics to reach the international first-class level, for the lightweight and "plastic instead of steel" to provide a solid foundation! In the three years since its establishment, New Forda has made remarkable achievements, which has aroused great interest of the author. What kind of business is this? Recently, I visited this company, which is located in Suzhou Industrial Park. Although the company is small in scale, it pays special attention to technology research and development. In the NFD experimental Center, excellent r&d talents with rich overseas working experience are gathered. More than 50% of the cost is invested in R&D every year, which makes the technicians of NEW FFD shout out: To be the Huawei of plastics! It is precisely because NFD attaches great importance to technology research and development and innovation that this insignificant "small company" will constantly break through technical barriers and successfully stand on the forefront of the industry of specially modified plastics. According to the person in charge of the company, the major progress is made by the joint development of NFD and a bearing company in China. The purpose of the development of nanometer superwear-resistant composite plastics is to replace metal bearings with plastic bearings, so as to achieve the dual goals of lightweight products and dryness reduction. It is well known that most of the mechanical moving parts are made of metal. Take the metal bearing as an example: the traditional metal needs lubricating oil, which has disadvantages such as dryness, lubricating oil pollution and high density. The wear-resistant nano plastics have many advantages, such as high production efficiency, low dryness, free maintenance (no lubricating oil), low cost and light weight. The success of this material research and development indicates that plastic bearings have become mature instead of metal bearings. It is believed that in the near future, nanometer superwear-resistant materials will shine in industrial automation, intelligence, transportation, medical treatment, textile machinery, automobile, aerospace and other industries. At present, domestic enterprises have already used this technical scheme, applied in some parts with high wear resistance requirements and achieved good application results. The following technical data are provided for manufacturers: PA66 nanocomposite technology is compared with the friction coefficient and abrasion loss of traditional wear-resistant additives The PEEK nanocomposite technology is compared with the friction coefficient and abrasion loss of traditional wear-resistant additives The POM nanocomposite technology is compared with the friction coefficient and abrasion loss of traditional wear - resistant additives For a well-known bearing manufacturer, New Forda has developed a bearing plastic with self-lubrication, high wear resistance (wear value can reach five times of metal), high temperature resistance, low noise, long life and other characteristics. Recently, the wear of bearings produced by using NFD nanometer crosslinked composite plastics decreased nearly 100 times! According to the data, after the cross-linking of nanomaterials and plastics, the material properties changed significantly. This great success laid a solid foundation for the development and growth of NFD in the wear resistant industry. We know that: the new first of all in composite material modification technique, super durable plastic research has always been a key research topic, composite modified plastic, high wear-resisting function as an important means, in achieving high strength, high wear resistance, light, functional area has a wide range of research and application value, is the new first modification technology as the core to further study. In this context, the new Forda after three years of continuous progress and efficient technology innovation! Only high wear resistant plastics have been developed with 60 kinds of plastics as the base material nearly 270

Common automotive plastics, automotive parts engineering plastics

What are the advantages of plastic as automobile material? First, the biggest advantage of the application of plastic in automotive materials is to reduce the weight of the car body Lightweight is the goal of the car industry, and plastics have a lot to show for it. The specific gravity of general plastics is 0.9~1.5, and the specific gravity of fiber-reinforced composite materials will not exceed 2, while in metal materials, the specific gravity of A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. This makes plastic the preferred lightweight material for cars. Second, plastic is easy to form, making it very convenient to process parts with complex shapes For example, the dashboard with steel plate processing, often need to process the forming of each part, and then separately with the joint assembly or welding, more procedures. And the use of plastic can be a molding, processing time is short, the accuracy is guaranteed. Third, enhance the buffering effect Front and rear bumpers and body decoration strips are made of plastic materials to reduce the impact of external objects on the sound of the car. In addition, plastic also has absorption and attenuation vibration and noise role, can improve ride comfort. Fourth, plastic corrosion resistance is strong, local damage will not corrosion Steel production once the paint is damaged or the early corrosion is not good will rust corrosion. The corrosion resistance of plastic to acid, alkali and salt is greater than that of steel plate. If plastic is used as body cover, it is very suitable to be used in areas with large pollution. Fifthly, modified plastics can adapt to the application requirements of different parts on the vehicle For example, bumpers should be of considerable mechanical strength, while cushions and backrests should be made of soft polyurethane foam. More conveniently, plastic colors can jump out through additives, saving the trouble of painting. Some plastic parts can also be electroplated, such as ABS plastic has a very good electroplating performance, can be used to make decorative strips, signs, switch knobs, wheel decorative cover, etc. High-function plastics are being used more and more in automobiles. The use of plastic helps reduce the weight of a car. For every 10 percent reduction in vehicle weight, fuel economy improves by 5 percent. Plastics can increase the flexibility of car manufacturers' designs. The successful application of plastic in automobile makes the cost of automobile lower. A simple injection molding plastic part can play the function of welding many metal parts together. Plastic can be moulded into a more complex shape than steel composition, which can reduce the number of parts used in the integration process. The plastic parts of the injection molding also have aesthetic effects that are difficult to achieve with traditional materials such as steel and glass, such as glass headlamp lenses replaced with polycarbonate materials. Environmental forces are pushing car makers to adopt plastic-based automotive glazes. Fuel consumption and carbon dioxide emissions are key considerations in many auto makers' assessments. Engineering plastics have been widely used in the automotive field due to their good comprehensive mechanical properties. In this paper, polyamide (PA), polymethacrylate (PMMA), polyformaldehyde (POM), polyamide (PU) and polycarbonate (PC) are mainly introduced. 1PA Polyamide, commonly known as nylon, has many types of PA in industrial use, such as PA6, PA66 and PA610. PA easy to print, easy to dye, excellent electrical properties; Resistant to drugs and oil. The common character of machinery is toughness, they all have high surface hardness, good tensile strength, good impact resistance, fatigue resistance, folding resistance, stress cracking resistance. The tensile and compressive strength of PA changes with temperature and moisture absorption, so water is a plasticizer of PA. After glass fiber is added, the tensile and compressive strength can be increased by about 2 times, and the temperature resistance can also be improved accordingly. The abrasion resistance of PA itself is very high, so it can work without lubrication. The disadvantages of PA include poor acid resistance, poor light resistance and poor pollution resistance. Due to the influence of thermal expansion and water absorption, the dimension stability of the parts is poor, and the shrinkage rate is 1 ~ 2%. It is necessary to pay attention to the dimension change of moisture absorption after forming. Water absorption rate is 100%, relative moisture absorption saturation can absorb 8%, suitable wall thickness: 2 ~ 3.5mm. Injection molding performance: PA due to the presence of amide group, strong water absorption and water absorption firm, therefore, in injection molding should be fully dried, generally to be dried at 120℃ 3-4 hours; The PA viscosity is small and the flow speed is fast. In order to prevent the nozzle from flowing
