Tianmeng
The core advantages of composite coatings:
Dual protection against wear and corrosion
Tungsten carbide has a hardness as high as Hv1400-1800, which can effectively resist the wear of pulp impurities and chemical corrosion. The inert property of Teflon (polytetrafluoroethylene) forms a chemical barrier to prevent erosion by acidic/alkaline slurries. The synergistic effect of the two extends the service life of the circular net by 3 to 5 times.
Non-stickiness enhances production efficiency
The surface energy of the Teflon coating is extremely low (18mN/m), which reduces the peel force of wet paper sheets by more than 60%, significantly decreases the occurrence of screen sticking and paper breakage, and can increase the operating speed of the paper machine by 15% to 20%.
The economy of online spraying
By adopting on-site spraying technology, there is no need to disassemble the circular mesh, reducing downtime by 70% and lowering the single maintenance cost by 40%. Taking a 1.8-meter diameter circular mesh as an example, the annual maintenance cost can be saved by 120,000 to 150,000 yuan after spraying.
Empirical evidence of Industry Application
The case of Jinan Tianmeng shows that after spraying, a certain specialty paper enterprise:
The paper breakage rate has dropped from 3.2 times per shift to 0.5 times per shift
The replacement cycle of circular mesh has been extended from 8 months to 3 years
The smoothness of the paper surface has increased by 18%
The extended value of technology
This technology complies with the green manufacturing requirements of "Made in China 2025" and has passed:
Reduce equipment scrapping (annual carbon reduction of approximately 2.3 tons per unit)
Reduce the amount of lubricant used (save 30% of anti-sticking agent)
Increase the yield rate (A-grade product rate +5%)
