Advantages of the Navector NHCF Series Silver Paste Filtration Screen in the Separation of High-Viscosity Slurries

The original design motivation of the NHCF series silver paste filtration screen is derived from the practical requirements of front-side silver paste manufacturing processes in the photovoltaic industry. Silver paste is a slurry with high solid content and high viscosity. Conventional screening equipment often encounters problems such as filter mesh clogging, low separation efficiency, and difficult maintenance when handling such materials. To address this challenge, Navector integrates advanced German filtration technology for high-value, high-viscosity coatings with its own innovative design, resulting in a filtration and screening system with strong adaptability and high operational stability.

The core components of the equipment include an independent integrated filter screen and an optimized filter media structure. The pore size of the filter media is kept precisely consistent during manufacturing, ensuring that the pores are not prone to deformation under high-load conditions. During filtration, the filter media does not deform due to the pulling effect of viscous slurries, guaranteeing stable filtration accuracy and long-term reliable operation of the equipment. The system adopts 800-mesh fine filtration technology, enabling high-precision filtration in a single pass, avoiding repeated circulation processes and reducing overall production costs.

During operation, the NHCF series filtration screen features automatic control functions. Once commissioning is completed, the equipment can autonomously complete the main filtration process without frequent manual intervention, meeting the automation requirements of modern production lines. This is particularly important for industries with fast production rhythms and stringent quality requirements, significantly improving production efficiency and ensuring process consistency.

During operation, the scraper steadily pushes the slurry through the filter screen while simultaneously performing necessary cleaning of the filter media surface to maintain continuous filtration capability. Navector adopts an external transducer design, allowing the equipment to achieve fine filtration down to the -8 micrometer level for highly viscous slurries with extremely high solid content under normal pressure conditions, without being affected by temperature fluctuations. The external configuration also reduces the risk of contamination and improves the equipment’s suitability for applications involving sensitive materials.

The NHCF series filtration screen also offers advantages in maintenance and cleaning. The integrated filter screen design allows for easy disassembly and installation, requiring minimal time for routine maintenance and not occupying excessive production personnel resources. The filter media can be thoroughly cleaned with ease, with no dead zones or hard-to-clean areas.

In the field of high-viscosity slurry separation, equipment stability, fineness, and automation level are key indicators for evaluating technological advancement. The NHCF series silver paste filtration screen provides high filtration precision, fine separation performance, and reliable automatic operation, helping enterprises enhance product quality control and strengthen process stability.

The NHCF series silver paste filtration screen precisely addresses the technical challenges associated with separating viscous, high-solid-content materials. Through refined filter media design, automatic control operation mechanisms, and optimized filtration processes, it achieves efficient, stable, and easy-to-maintain separation performance. The application value of this equipment in high-viscosity slurry separation processes is evident, providing solid technical support for customers to improve production efficiency and product quality.
