Requirements for Plastic Material Modification in Multiple Industries
Automotive Industry
· Lightweighting: As environmental and fuel standards become more stringent, lightweighting is achieved through modifications such as high - strength fiber reinforcement and micro - foaming, reducing weight while ensuring strength and safety.
· High - performance: Auto parts need to be heat - resistant, corrosion - resistant, have low emissions, and maintain stable and long - lasting performance. For example, engine compartment parts should withstand high temperatures, exterior parts should be weather - resistant and impact - resistant, and interior parts should meet low - VOC emissions standards.
· Appearance and Texture: With increasing consumer demands, special materials can be added or surface treatments can be applied to imitate metal, leather, or wood grain, enhancing aesthetics and quality.
Electronics Industry
· Miniaturization and Thin - walling: As electronic products become smaller and lighter, materials for casings and structural components need to have high strength, high rigidity, and good dimensional stability. Modified PC, for instance, meets the requirements of mobile phone mid - frames.
· Heat Dissipation and Shielding: With significant heat generation during operation, thermally conductive modified plastics are needed for heat dissipation. To prevent electromagnetic interference and information leakage, conductive fillers are added to plastic casings to achieve electromagnetic shielding.
· Safety and Environmental Friendliness: Casings need to be flame - retardant and anti - leakage. With growing environmental awareness, materials are required to be recyclable and halogen - free.
Medical Industry
· Biocompatibility: Medical plastic products come into contact with the human body. Surface modification and addition of biocompatible additives prevent immune, allergic, and other adverse reactions.
· Functionality: Requirements vary depending on the application scenario. Surgical instruments need to be wear - resistant, corrosion - resistant, and fatigue - resistant. Drug - release systems require controllable release. Implantable devices need to have osteoconductivity and tissue - inducing properties.
· Safety and Reliability: Quality and safety are crucial for patients. During modification, strict control of additives ensures material purity and stability, ensuring no issues during long - term use.
Industrial Industry
· High - temperature and Corrosion Resistance: Equipment components in industries like chemicals are in harsh environments. Plastic modification meets the requirements of high - temperature and chemical corrosion resistance.
· High Strength and Toughness: Key components such as transmission parts, conveyor belts, and pipes are strengthened and toughened to improve strength and toughness, extending their service life.
· Wear Resistance and Self - lubrication: For parts in relative motion like bearings and gears, adding wear - resistant fillers and lubricants improves equipment operation efficiency and reliability.
However, this kind of modification is not perfect. It may lead to a decline in some of the original properties of plastics, such as insulation performance, corrosion resistance, and gloss. Nevertheless, experienced technicians, relying on their professional knowledge and rich practical experience, can carefully design appropriate formulations and adopt effective measures to minimize these negative performance changes, ensuring that plastics can maintain their original performance stability as much as possible while obtaining new performance advantages.
