Microspectroscopy technology: Do you know all the four major modification application directions of polycarbonate PC?

Toughened PC Toughened PC is divided into ordinary grade toughened PC and high-flow toughened PC: Ordinary grade toughened PC: It has good impact resistance, adjustable impact performance, small molding shrinkage, good size stability, good weather resistance, high low-temperature impact resistance, and can be sprayed. It is mainly used in electronic and electrical products such as thin-walled products, auto parts, and mobile phones, such as mobile phone casings.

The modified application of polycarbonate (PC) aims to expand its application scope in electronic appliances, auto parts, thin-walled products, medical and other fields, mainly focusing on four major directions: toughened PC, flame retardant PC, glass fiber reinforced PC and PC/ABS alloy. This not only improves the physical and mechanical properties of the PC, but also enhances its adaptability in different environments and applications. Toughened PC Toughened PC is divided into general purpose grade and high flow grade.

The PC modification project has significantly improved the performance of polycarbonate through blending, filling and other technologies, enabling it to achieve diversified applications such as high strength, heat resistance, and flame retardant in automotive, electronics, and medical fields. The purpose of the modification is to break through the performance limitations of pure PC materials by toughening, improving processing properties, reducing residual deformation, and increasing flame retardancy, so that they can adapt to complex industrial needs.

What is the detailed explanation of the injection molding and injection process

Injection injection injection is a mass production processing process that combines plastic molding and surface coating. First, plastic blanks that meet the size requirements are prepared by an injection molding machine, and then the surface of the blanks is covered with decorative or functional coatings through a spraying process. It is widely used in consumer electronics, home appliances, automotive interiors, hardware and plastic exterior parts and other fields.

The core technical points of the injection molding process focus on the four major aspects of injection molding accuracy control, pre-injection pretreatment, spray parameter matching, post-curing and quality control. The core goal is to ensure coating adhesion, appearance consistency and product service life.

The standard operating process of the injection molding and injection process is divided into five core links: workpiece injection molding, pretreatment, injection coating, curing and drying, and quality inspection and packaging. Each link needs to match corresponding equipment and process parameters to ensure product quality.

The injection process is a composite processing process that first completes the injection molding of plastic/metal substrates, and then achieves appearance decoration and functional protection through spray coating. The core application is in the processing of various industrial and civil appearance parts that require both molding and surface treatment. Scenes, covering many fields such as consumer electronics, automobiles, and home appliances.

According to customer needs, the industry can also produce products with different properties, such as high temperature resistance, friction resistance, ultraviolet resistance, alcohol resistance, gasoline resistance and other characteristics. In the field of electronic products, plastic products can achieve a more refined appearance after being sprayed, such as USB flash drives, MP3 players, cameras and network peripheral products.

Can steel structures be subjected to ultrasonic flaw detection after painting?

Whether steel structures can be subjected to ultrasonic flaw detection after painting depends on the state of the paint layer. When the paint layer is uniform and adheres well to the surface of the workpiece, the sensitivity of ultrasonic testing will not be affected. If the paint layer is uneven, the surface is not smooth, or there is delamination or cracking, the paint layer should be removed to ensure the accuracy of the test results. Ultrasonic testing is a non-destructive testing method that can inspect the quality of the surface and interior of a workpiece without damaging the original state of the workpiece or material.

All second-level welds need to be subjected to ultrasonic flaw detection. If ultrasonic flaw detection cannot determine defects, radiographic flaw detection should be used. In general, the parts of light steel structure factories that require flaw detection are: butt welds of beams and columns, fillet welds connecting auxiliary end plates and beams, T-welds of crane beam upper flanges and compound plates, etc. It is not possible to detail all welds that require flaw detection here. Generally, the design instructions of drawings will contain requirements for weld grade, and you can make a judgment based on this.

Testing methods: flaw detection engineers select radiographic testing, ultrasonic testing, magnetic particle testing, penetration testing, TOFD testing and other methods as needed. Outcome output: A systematic "Non-destructive Inspection Report" will be issued after the project is completed. Full-process tracking: flaw detection engineers are fully in place to provide timely feedback on the testing status to customers.

What are the technical points of the injection molding and injection process

1. The core technical points of the injection molding and injection process focus on the four major aspects of injection molding accuracy control, pre-injection pretreatment, spraying parameter matching, post-curing and quality control. The core goal is to ensure coating adhesion, appearance consistency and product service life.

2. The overall process framework follows the complete process of "material preparation → injection molding → blank processing → oil spray coating → curing and baking → post-treatment inspection". The core is divided into two core aspects: injection molding blank preparation and oil spray coating.

3. Water nozzle treatment: Use an automatic water nozzle machine or manual scissors to remove the injection nozzle to obtain plastic blanks without excess waste. Pre-injection treatment (1) Product cleaning and removal of mold release agents and dust: Use an ultrasonic cleaner with pure water to rinse the product, or use a dust-free cloth dipped in isopropyl alcohol to wipe the surface to remove residual mold release agents and adhered dust in injection molding.

4. The standard operating process of the injection molding and injection process is divided into five core links: workpiece injection molding, pretreatment, injection coating, curing and drying, and quality inspection and packaging. Each link needs to match corresponding equipment and process parameters to ensure product quality. Injection molding of workpieces (1) Raw material pretreatment: ABS, polypropylene and other injection molding raw materials are mixed according to the production ratio. Engineering plastics need to be dried at 80 - 120℃ for 2 - 4 hours to remove free moisture to avoid bubbles and flow mark defects after molding.
