As is well known, the material of acrylic lenses is polymethyl methacrylate, abbreviated as PMMA. We usually refer to it as organic glass. After electroplating with PMMA, a mirror effect product is formed. Usually, different mirrors are produced according to customer needs due to different electroplating conditions, such as single-sided mirrors produced by electroplating on one side, double-sided mirrors produced by electroplating on the other side, rubber mirrors produced by electroplating on other different plastics, semi lenses produced by electroplating on semi transparent plastics, paper mirrors, etc. Acrylic lenses are widely used and very convenient to use, so they are loved by people and are also seen and used in our daily lives. Due to its stable chemical properties, it can maintain good stability not only in acidic environments but also in alkaline environments, both acid and alkali resistant. They are called plastic crystals. To put it bluntly, transparent plastic lenses. Due to its stable chemical properties, it is also the preferred choice recommended by the factory to customers. The advantages of acrylic lenses: 1. The transparency can be adjusted according to customer needs, with a transparency of up to 92%, which can generally meet customer needs. 2. Chemical stability is strong, acid and alkali resistance is good, so it will not corrode acrylic lenses due to bad outdoor environment. 3. Replacing glass lenses, as is well known, is a common type of lens. The great advantage of these lenses is their high transmittance, which is commonly used. But there is a particularly big drawback, which is that accidentally breaking it can cause subsequent damage to the human body, but acrylic lenses have overcome this very well. 4. Strong hardness. The acrylic lenses currently used are generally 1 meter high and have no signs of falling on the ground. But if you replace glass lenses, even if they are 20 centimeters high, they can still break into pieces. 5. Good glossiness, the glossiness of acrylic lenses can look 99.99% glossiness, so many people like to use acrylic lenses as trophies, and the ones inside the medals look great. 6. Strong plasticity. After high-temperature heating, acrylic lenses can be modified according to their shape or images can be modified using laser. It can be customized according to needs, very convenient. Comparing acrylic lenses and plastic lenses, it can be found that the effects of the two types of lenses are almost the same. However, specifically, acrylic lenses are more affordable and cost-effective, while PC lenses are relatively expensive and have lower cost-effectiveness than acrylic lenses. The main difference between acrylic lenses and PC lenses lies in their different uses. Acrylic lenses are mainly used in daily life. Due to its high thermal performance, PC lenses are commonly used in space, aerospace, and other fields. It can also be used for bulletproof purposes. So according to their respective performance, there are different prices and market uses. In terms of processing, acrylic lenses are relatively easy to process, while plastic lenses are relatively troublesome to process. At present, acrylic lenses can be made through mechanical processing, thermoplastic molding, blow molding, plastic molding, solvent bonding, hot stamping, screen printing, and main vacuum electroplating methods, making secondary processing more convenient.  

What is a conductive rubber button like? With the development of society and the progress of technology, electromagnetic radiation and static electricity generated in electronic equipment and other fields have brought certain harm to the environment. conductive polymer materials can effectively reduce or eliminate electromagnetic interference, electromagnetic radiation and static electricity. Conductive polymer materials are mainly divided into structural type and composite type. Conductive polymer with structure is a kind of conductive material with polymer itself or after modification. Composite conductive polymer material is a functional composite material which is made of polymer material filled with conductive filler through mixed vulcanization. The type, resistivity, and dosage of conductive fillers are the main factors affecting the conductivity of conductive rubber. This article mainly introduces the research progress of carbon based conductive fillers filled with conductive rubber. 　 What is a conductive rubber button like? When it comes to conductive rubber, many people may not know its specific properties, but when it comes to its use, sealing, and electromagnetic shielding, many people benefit greatly from it. In fact, conductive rubber has a wide range of applications in many fields, whether in commercial packaging or military equipment applications, its exquisite and capable figure can be seen everywhere. What is a conductive rubber button like? Conductive rubber is a rubber with many conductive particles evenly distributed in silicone rubber, such as silver plated glass, silver plated aluminum, silver, etc. When it needs to be used for conductivity, a certain amount of pressure will cause these conductive particles to deform, resulting in contact conductivity. Currently, many conductive rubbers can be extruded by molding, some in sheet or die cut shapes, thus meeting the needs of different groups. The types of conductive rubber can be divided into aluminum silver plated conductive rubber, copper silver plated conductive rubber, glass silver plated conductive rubber, and pure silver conductive rubber according to the material. For aluminum silver plated conductive rubber, it has excellent shielding performance and smoke resistance, while copper silver plated conductive rubber has excellent conductivity, and glass silver plated conductive rubber has a good cost-effectiveness. Pure silver conductive rubber has outstanding advantages in mold resistance. What is a conductive rubber button like? Conductive rubber has excellent electromagnetic sealing and water vapor sealing capabilities. If a certain pressure is applied to it (with a suppression frequency of 40GHz), it will have good conductivity. Due to this special performance, various conductive rubber products are widely used in military electronic equipment such as aerospace and weapons, bringing great convenience to the manufacturing of various products. What is a conductive rubber button like? Conductive silicone rubber is a product based on silicone rubber, filled with various conductive materials and crosslinking agents, and vulcanized. Its conductive materials include graphite, copper powder, silver powder, acetylene carbon black, etc. Compared with other conductive rubbers, it has low resistivity and slightly lower hardness, making it particularly suitable for manufacturing conductive silicone rubber products with complex shapes and high structural requirements. Therefore, it is also a widely used type of conductive rubber, and the number of "appearances" on the market is increasing.

Conductive rubber buttons are one of the many electronic product buttons, and their main function is to achieve conductive functions through conductive rubber buttons. When the conductive rubber button is pressed, the conductive rubber under the button can achieve electrical connection with the contacts below. When the conductive silicone key is released, the conductive rubber under the key bounces up and does not communicate with the contacts below. Conductive rubber buttons are mainly used for dictionary keys, remote control keys, POS machine keys, scanner keys, password keys, keyboard keys, single point keys, etc. So how does conductive rubber buttons achieve conductivity, that is, what is the conductive principle of conductive silicone buttons? It's actually very simple: the conductive material of silicone rubber buttons is a black conductive adhesive, and by adding conductive fillers to the conductive adhesive, the conductive effect can be achieved. Diameter, length, width and height, key stroke distance, pressure requirements, product hardness, color, conductivity requirements, etc. When purchasing conductive silicone keys, the characteristics of silicone products should be considered. The production process of conductive rubber buttons: 1. First, ask the customer to provide us with 3D drawings or samples of the product style to be customized, and then design and make drawings based on the information on the drawings or samples, usually using flat drawing software; 2. After designing the production drawings, the mold can be opened. Professional mold masters use CNC machine tools to design and program, and then turn on the machine. If it is a complex product, it needs to be demolded using spark copper workers. So the technical content is relatively high, and the mold opening time is relatively long. After the mold is made, production is easier; 3. The materials used for making conductive rubber buttons are environmentally friendly silicone and rubber materials, with a general hardness between 29 and 69; 4. After the mold production is completed, it can be installed on a professional production machine to start construction; 5. After the finished product is produced, strict quality inspection should be carried out, and any non-conforming products should be scrapped; 6. Generally, the conductive rubber buttons produced will have residual burrs, so the products at this time need to be treated by employees; 7. After completing the post processing, quality testing should also be conducted to see if there are any non-conforming products. After the inspection is completed, packaging can be carried out according to customer requirements. The principle of conductive rubber buttons is the same as ordinary buttons, that is, after pressing a button, the two contacts are connected. The difference is that ordinary buttons are soldered onto the solder pad, while conductive rubber buttons are fixed to the product casing. Conductive silicone buttons are not only used in TV remote controls, but also in many other consumer electronics, medical products, handheld instruments and industrial control products.

Silicone seals have many advantages, as their heat resistance can work at very low temperatures, reaching as low as - tens of degrees Celsius, and they have excellent antioxidant and ozone resistance in the air. Due to the molecular structure of silica gel, silica gel seals have good permeability and gas selectivity, and because they are non-toxic and tasteless, they can be used in many food and medical industries. Silicone is highly favored for its environmental performance and is widely used in the production of various silicone seals. Physical characteristics: 1. Good elasticity, tear resistance, and resistance to neutral solvents; 2. Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber; 3. Cold resistance: Ordinary rubber has good elasticity after -20-30 ° C, while silicone rubber still has good elasticity at -60-70 ° C. Some special silicone rubber can withstand very low temperatures, such as low-temperature sealing rings; 4. Excellent resistance to ozone and oxide corrosion. Performance of silicone seals: 1. It has high wear resistance and automatic elastic compensation function on the worn part of the working sealing ring surface, thereby improving the service life of the sealing ring. 2. It has good self-lubricating performance, so it can be safely used for some seals that cannot be lubricated. 3. Installation is simple and convenient because its structure is simpler than other types of seals. 4. It has good extensibility and compressibility, so that the sealing ring can adapt to more working scenarios. 5. High temperature resistance is another excellent performance, as it often faces high temperature environments under certain working conditions. Excellent insulation performance is another advantage of silicone seals, and if carbon black, nickel powder, and aluminum powder are added appropriately, the conductivity can be increased. Silicone sealing rings also have hygroscopicity, which can absorb and isolate moisture in the environment, but have poor resistance to water vapor. Silicone seals also have their drawbacks, so under what circumstances is it not suitable to use silicone seals? 1. Silicone seals are not suitable for working environments with pressures exceeding 50 pounds; 2. Silicone rubber is compatible with most oils, compounds, and solvents, and has good acid and alkaline resistance, but has little resistance to hydrocarbon and aromatic oils. 3. In most concentrated solvents, oils, concentrated acids, and dilute caustic solutions, it is not recommended to use silicone seals. With the development of time and the advancement of silicone technology, some special components of silicone also have properties such as radiation resistance, flame retardancy, and oil resistance; Special silicone rubber, such as fluorosilicone rubber and borosilicate rubber, also shine brightly in their respective fields. Choosing the right product in the right position, high-quality silicone seals can play an important role in critical moments, truly achieving the goal of "one person can handle the situation, ten thousand people cannot open it".

Decorative panels are the main materials we can use in decoration. Generally, we can use decorative panels in decoration. Decorative panels play an important role in the process of decoration. They are widely used in the surface decoration of wooden doors, furniture, baseboard, etc. Decorative panels are a good decoration material that is different from other oil mixing methods in its current position and can bring different decoration effects to the decoration. So, what issues should we pay attention to when selecting decorative panels? 1. Identify the difference between artificial veneer veneers and natural veneer veneers: The texture of artificial veneer veneers is basically straight, with regular texture patterns. As a natural texture, natural wood patterns have a large natural variability in texture patterns, and there are no specific rules to summarize. 2. It has excellent decorative properties: The appearance of the decorative board has a good appearance, good aesthetics, and the material is also relatively fine and uniform, with clear color and beautiful wood grain. The texture of the matching board flower should be arranged according to a certain pattern, with similar wood colors and almost parallel seams and board edges. 3. There should be no obvious defects on the surface of the decorative panel: The selected surface of the decorative panel should be smooth and free of burrs, hook marks, and planer marks. No adhesive penetration will occur. Try to choose surfaces that are free from cracks, cracks, and inclusions, Panel of resin capsules and resin channels; The natural warpage of the entire board should be minimized to avoid sand penetration caused by improper sanding process operation of the substrate. 4. The structure of the adhesive layer is very stable and there is no phenomenon of opening the adhesive: attention should be paid to the surface between the veneer and the substrate, and there should be no bulging or layering between the internal parts of the substrate. 5. Method of using scabbard The method of using a scabbard to test the bonding strength: This method is a very intuitive and effective way to test the bonding strength. Use a sharp bottle mouth blade to pry open along the adhesive layer. If the adhesive layer cracks and the wood is damaged, it indicates poor bonding strength. 6. Choose boards with low formaldehyde emissions: When choosing boards, try to choose decorative panels that do not have irritating odors. Because a large odor represents a high level of formaldehyde release, as well as a high level of pollution and harm 7. Choose products with a clear production enterprise: The vast majority of products with a clear factory name, address, and trademark have relatively reliable performance.

Parts made of plastic compounds containing anisotropic thermal conductive fillers represent directional thermal conductivity and anisotropic material properties. Innovative processes help improve the thermal conductivity of components and optimize their performance by changing the direction of the filler. Why is it difficult for plastic phone shells to dissipate heat? How to improve? Due to the increasing demand for electromechanical systems in the industry, especially the trend towards miniaturization, people are beginning to explore new concepts of thermal management. Due to the impact of miniaturization, the available space and air in the modules are reduced, and active cooling components such as ventilators are also being scrapped. One way to meet these new requirements is to use plastic component shells to eliminate heat. Firstly, plastic shell manufacturers believe that the more thermal conductive fillers, the worse. Plastic itself has low thermal conductivity, so it is often necessary to use thermal additives to make thermal materials. In addition to functional integration, thermal conductive plastics also have special properties - electrical insulation, without metal materials (although their thermal conductivity and energy are very good). The combination of these advantages and the high design freedom of plastic components provide new methods for thermal management of technical components. In addition, plastic shell manufacturers believe that thermal conductive plastics can be obtained from multiple suppliers in the market, mostly between 1-20W/mK. The investigation shows that the thermal conductivity of thermal conductive plastics is only 3-5 W/mK, which can improve the heat management of electronic modules. As is well known, the thermal conductivity mainly depends on: 1. Thermal conductivity of plastic 2. Packaging type 3. Filler shape (spherical, sheetlike, or fibrous) 4. Filler size 5. Charging capacity However, the amount of filler used not only has a significant impact on thermal conductivity, but also on other properties. The higher the filler content, the more the thermal conductivity does not increase proportionally, and the processing performance of thermal conductive plastics significantly decreases. In addition, thermal conductive fillers are generally more expensive than engineering plastics, so as the content of the filler increases, the material cost will significantly increase. When selecting thermal conductive plastics, the relationship between thermal conductivity, processing performance, and material cost should be evaluated. For thermal conductive plastics, the principle of 'more is better' does not apply. 2、 The thermal conductivity of the formed flow direction product is relatively good The research results of both thermal conductive plastics and fiber reinforced plastics show that the use of unequal axis filling materials can exhibit anisotropic material properties in components. Therefore, this anisotropy depends on the value of the processing. The fluid dynamics acting on the fillers during the processing have a significant impact on their taste. Due to the fact that the thermal conductivity of unequal axis fillers is mainly reflected in the preferred direction (such as the fiber length direction), the direction of the filler will have a significant impact on the anisotropic thermal conductivity of the finished component. When using traditional processing methods to produce flat or frame components, the filling material mainly follows the flow direction and width direction. Especially in thin-walled components, the filling material is rarely aligned with the thickness direction. Therefore, good thermal conductivity mainly occurs in the flow direction and width direction. However, these filling directions are not applicable to all application fields. For structural components, internal heat loss is mainly eliminated on the shell wall (thickness direction). From this perspective, high thermal conductivity in the thickness direction is very important. Unfortunately, the orientation of fillers achieved using traditional processing methods is not ideal for this application. As the filling content increases, only the thermal conductivity in the thickness direction will slightly increase, but the other performance of the component will decrease. 3、 Plastic shell manufacturers believe that the new process can improve the thermal conductivity in the thickness direction As mentioned by the plastic shell manufacturer, the anisotropy of thermal conductive plastics, which is not dominant, is mainly affected by the flow behavior during the processing. This directional adjustment is achieved by improving the melt flow inside the mold, while causing changes in shear flow and tensile flow.
