AI Technical Summary

Technical Problem

Traditional filter rod materials, such as cellulose acetate and cellulose propylene, have poor degradation capabilities, leading to difficulties in waste disposal, serious environmental pollution, and difficulty in meeting the adaptability requirements of paper filter rod forming equipment.

Method used

The filter cartridge is made of all-plant fiber paper, including coniferous wood fiber, bamboo fiber, mulberry bark fiber, mulberry bark fiber and hemp fiber. It is prepared by mixing and sizing agents in a specific ratio to meet the machine adaptability of paper filter rod forming equipment, and to produce paper filter rods with good appearance, stable circumference and pressure drop.

Benefits of technology

This method achieves the environmental friendliness of easily degradable paper filter rod materials, meets the adaptability requirements of filter rod molding equipment, and produces filter rods with stable appearance and performance.
