Product Description: White copper bar is a nickel-zinc-copper alloy. White copper bars based on copper and nickel-zinc alloy with the addition of other elements such as lead, manganese, and aluminum are correspondingly referred to as lead white copper bar, manganese white copper bar, aluminum white copper bar, etc. Copper-nickel-zinc alloys exhibit good corrosion resistance, moderate strength, high plasticity, and can be processed under hot and cold pressure conditions. They also possess excellent electrical properties, making them not only suitable as structural materials but also important for high-resistance and thermocouple alloys.Common white copper bars mainly include four grades: B0.6, B5, B19, and B30. The most commonly used grades in the market are B12, B18, and C7941. The American standard includes a wider range of grades. White copper bar is a continuous solid solution formed by Cu and Ni, with a face-centered cubic lattice, as shown in Figure 1-18. When the temperature is below 322 degrees Celsius, the copper-nickel phase diagram exhibits a relatively broad metastable decomposition region in terms of composition and temperature. Adding a third element such as Fe, Cr, Sn, Ti, Co, Si, or Al to Cu-Ni alloys can alter the range and position of the metastable decomposition region while also improving certain properties of the alloy.Common white copper bars have good cold and hot working properties. They can be easily processed into various shapes such as plates, strips, tubes, bars, profiles, and wires. They also have good welding performance, allowing for soft and hard soldering, gas-shielded arc welding, and resistance welding. Their machinability is 20% that of free-cutting brass HPb63-3.Common white copper bars offer good corrosion resistance, moderate strength, high plasticity, and the ability to undergo cold and hot pressure processing. They also exhibit excellent electrical properties, making them not only suitable as structural materials but also important for high-resistance and thermocouple alloys. more>

Product Description: Infrared pneumatic fully automatic pressure-free air doors are intelligent ventilation control devices that integrate infrared sensing technology, pneumatic drive systems, and pressure-free balance structures. They are widely used in scenarios such as mines, tunnels, and underground engineering where strict control of airflow is required to ensure the safe passage of personnel and equipment. Their core features include automated sensing and drive for hands-free operation, while utilizing a pressure-free structure to balance environmental wind pressure, enhancing device stability and service life.Core Components1. Pressure-Free Door Body StructureBalanced Design: The door body adopts a dual-leaf symmetrical structure connected to the door frame via hinges. When opened, the two leaves experience opposing forces, counteracting wind pressure (positive or negative) inside mines or tunnels, reducing opening resistance, and preventing wind pressure from damaging the door body.Material Selection: The door body is typically made of high-strength steel plates, composite materials, or corrosion-resistant wood, with surface treatments for anti-corrosion and anti-rust properties, adapting to harsh underground environments with high humidity, dust, and corrosive gases.Sealing Performance: Rubber sealing strips are installed between the door frame and the door body to ensure a tight fit when closed, preventing airflow short-circuiting and maintaining ventilation system stability. 2. Infrared Sensing SystemSensing Device: Infrared sensors (through-beam or diffuse reflection type) are installed on both sides of the door body to detect movement of personnel, vehicles, or objects within a certain range (typically 1-5 meters).Signal Processing: The sensors transmit detected signals to the control system, which determines whether to trigger the door opening command, avoiding manual operation and reducing human contact.Anti-Interference Design: Equipped with dustproof and waterproof functions to resist interference from dust and water mist, ensuring sensing accuracy in complex environments.3. Pneumatic Drive SystemPower Source: Powered by compressed air, the system drives the door body to open and close via pneumatic valves, cylinders, air tubes, and other components. Compared to electric drives, pneumatic systems produce no sparks, making them suitable for flammable and explosive environments (e.g., coal mine gas areas) with higher safety.Motion Control: The cylinder piston rod is connected to the door body, with the extension and retraction of the piston rod controlled by the charging and discharging of compressed air, enabling smooth opening and closing of the door body.Speed Regulation Device: The door opening and closing speed can be controlled by adjusting the flow rate of the pneumatic valve (typically 3-5 seconds for opening and 5-8 seconds for closing), preventing impacts from overly fast movements or reduced passage efficiency from overly slow movements.4. Automatic Control SystemController: The core control unit receives signals from infrared sensors and controls the pneumatic valve actions based on preset logic (e.g., opening when an object is detected, delayed closing, bidirectional interlocking, etc.).Interlocking Function: Dual-leaf door bodies or multiple sets of air doors feature interlocking logic, meaning when one side door is open, the other side door is forcibly locked to prevent simultaneous opening and airflow short-circuiting.Protection Mechanisms: Include overload protection (e.g., automatic stop or reverse operation when the door body encounters resistance, preventing injury to personnel or equipment), delayed closing (adjustable waiting time to accommodate the passage speed of personnel/vehicles), and fault alarms (e.g., audible and visual alarms for insufficient air pressure or sensor malfunctions).Working PrincipleSensing Trigger: When personnel or vehicles enter the detection range of the infrared sensor, the sensor sends a signal to the controller.Command Execution: After confirming the signal is valid, the controller drives the pneumatic valve to act, allowing compressed air to enter the cylinder. The piston rod extends, pushing the door body to open smoothly.Passage Process: The door body opens to its maximum angle (typically 90°) and remains open, waiting for personnel/vehicles to pass through.Automatic Closing: After passage is complete, the sensor detects no objects in the area, and the controller initiates a delay program (delay time adjustable, e.g., 5-30 seconds). After the delay, the pneumatic system reverses, the cylinder exhausts air, and the door body slowly closes under gravity or a reset mechanism.Safety Locking: After the door body closes, the controller triggers the interlocking mechanism to ensure the same-side or opposite-side air doors do not open erroneously, while the sealing structure ensures effective airflow control.Main Application ScenariosUnderground Mines: Used in main transportation roadways, return air roadways, and mining area stone gates in coal mines and metal mines to control airflow direction and volume, preventing gas and dust accumulation, and ensuring underground ventilation safety. more>

Product Description: South China Supplier Wholesale High-Quality Versatile Antibacterial Masterbatch for Various Plastics, Food GradeProduct Introduction:IHeir products are used to protect various plastic materials from microbial attack and degradation. Antibacterial plastic technology is not a surface application but is developed by the materials engineering team. It directly integrates with the material. Compared to surface applications, this method offers many advantages. Firstly, the antibacterial components are evenly distributed throughout the processed part or object. Therefore, the protection of our antibacterial plastic products will not wear off, and functionality will not be compromised, keeping the surface intact. Even if bacteria merely approach the surface, it still provides protection. Thus, plastic antibacterial masterbatch offers very durable and powerful protection. Compared to other antibacterial plastic technologies, plastic antibacterial masterbatch does not gradually crack or peel over time. The production of antibacterial plastic masterbatch is straightforward. IHeir synthesizes antibacterial active ingredients into plastic masterbatch, which is then added during the plasticization process. The additive particles are mixed with raw materials in the usual way to produce the product. This makes the handling of antibacterial plastic additives safer and easier to use. IHeir engineers work with a variety of materials, from plastics (polyolefins, ABS, PS, cross-linked plastics such as polyurethane, acrylic, and polyester) and engineering resins (such as PC, soft PVC, silicone, and rubber), to powder coating materials, and even cement-like materials (such as grout). We have over 20 different active ingredients to choose from, allowing solutions to be tailored to specific problems rather than offering just one or two types of antibacterial masterbatch.Introduction to Plastic Antibacterial Masterbatch:Plastic antibacterial masterbatch is a highly efficient antibacterial masterbatch that widely inhibits the growth of Gram-positive and Gram-negative bacteria. Due to its slow migration rate and high activity, it offers superior antibacterial performance in plastic products compared to others. It achieves an appropriate balance between material compatibility and migration, making its antibacterial performance excellent in plastic granules. Plastic antibacterial masterbatch is suitable for all common materials, maintaining an appropriate balance between material compatibility and migration. Its thermal stability can reach up to 240°C.Application Scope:It is recommended to use plastic antibacterial masterbatch at temperatures not exceeding 240°C. Suitable polymers include polyolefin polymers (polypropylene, low-density or high-density polyethylene), ethylene-vinyl acetate copolymer, methyl methacrylate, polystyrene, unsaturated polyester, polyurethane, thermoplastic polyurethane, formaldehyde-urea resin, latex, cellulose acetate, etc. The application of plastic antibacterial masterbatch in PVC and ABS depends on specific conditions. It is mainly used in sanitary facilities (including toothbrushes and toilet seats), appliances, garbage, shoe insoles, mats, and hospital equipment.Product Advantages:As one of the most effective plastic antibacterial masterbatches, it prevents bacterial growth on plastic surfaces, avoiding discoloration or odor. Plastic antibacterial masterbatch is an ideal product for meeting hygiene standards according to the specific requirements of finished products.
