Polycarbonate
Polycarbonate (PC) is an amorphous thermoplastic engineering plastic. With outstanding impact resistance, optical transparency, thermal stability and dimensional accuracy, it has become an indispensable key material in electronics, automotive, optics, medical and other industries. Its wet processing (e.g., slurry post-polymerization treatment, wet grinding) imposes extremely high requirements on equipment homogenization, sealing and grinding performance, which directly affect final product quality and downstream application performance.
Benefiting from its comprehensive performance advantages, PC is widely used in various high-demand industries:
Electronics & Electrical Industry: Mobile phone/laptop housings, connectors, LED lamp shades, leveraging its excellent insulation and impact resistance;
Automotive Industry: Headlight lenses, dashboard components, lightweight body parts, combining weather resistance and impact performance;
Optics Field: Eyeglass lenses, optical lenses, optical disc substrates, relying on its high transparency and low birefringence;
Construction & Security: Bulletproof glass, daylighting panels, safety windows, providing high-strength protection;
Medical & Food Industry: Disposable syringes, medical containers, food-grade packaging materials, meeting compliance and safety requirements.
Process
In PC wet processing, the industry commonly faces three core challenges:
Uneven solid distribution in slurry: When PC exists in slurry form, solid stratification and uneven distribution tend to occur, resulting in uneven stress during grinding, wide particle size distribution of the final product, and inconsistent downstream molding;
Sealing and leakage risks: Slurry systems in PC wet processing are prone to mechanical leakage due to defective equipment sealing, causing material loss, environmental pollution and potential safety hazards, posing strict requirements on equipment sealing performance;
Feed agglomeration and particle size control bottlenecks: Large abnormal agglomerates easily form in PC slurry. Traditional equipment cannot quickly break agglomerates, leading to low grinding efficiency and failure to achieve precise particle size control, which fails to meet the strict requirements of high-end applications for particle morphology.
