Corrosion-resistant, wear-resistant, non-stick paper drying cylinder with Teflon and tungsten carbide coating

1. The main advantages of the paper drying cylinders with Teflon and tungsten carbide coating are as follows:

1.1、Surface performance advantages:

1.1.1. Excellent non-stick property: The Teflon component provides extremely low surface energy, making it difficult for paper sheets, adhesives, and slurries to adhere to the cylinder surface, significantly reducing problems such as sticking, clogging, and accumulation of dirt. The paper peels off more smoothly.

1.1.2. Ultra-high hardness and wear resistance: The tungsten carbide provides a high-hardness base, resisting scraper wear, dry screens / cloth friction, and making the cylinder surface less prone to scratches, wear, and maintaining good flatness over time.

1.1.3. Smooth and uniform surface: The coating is dense and flat, without the common micropores and rough spots of chrome plating, improving the smoothness, glossiness, and uniformity of the paper, and reducing paper defects.

1.2、Heat resistance and thermal conductivity

1.2.1. Stable heat resistance: The composite coating can withstand the conventional high-temperature drying environment of paper drying cylinders, and will not age, flake off, or change color over time.

1.2.2. Stable thermal conductivity: The coating is thin and has high density, with low thermal resistance and uniform heat transfer, avoiding local overheating or uneven drying, and improving drying efficiency and energy utilization rate.

1.3、 Corrosion resistance and service life

1.3.1. Strong resistance to chemical corrosion: It can withstand acids, alkalis, humid air, bleaching agents, etc. in the paper-making environment, and the cylinder surface will not rust or be corroded.

1.3.2. Ultra-long service life: The dual protection of wear resistance and corrosion resistance, with a service life three to five times longer than ordinary chrome-plated drying cylinders, significantly extending the maintenance cycle.

1.4、 Production operation advantages

1.4.1. Reduce breakage rate;

1.4.2. Decrease material consumption

1.4.3. Reduce chemical usage, with good non-stick effect

1.4.4. Easy to clean and maintain, with less accumulation and easy cleaning, short downtime for cleaning, and reduced maintenance workload and downtime losses.

1.5. Product quality advantages: Improve paper-making quality, with a clean cylinder surface without impurities, no stick marks, no paper sticking, no stains, no scratches, no damage to the paper, and more stable appearance and physical indicators.

2. Core application scenarios

2.1. Suitable for waste paper pulp, high moisture strength, prone to stickiness and clogging, and prone to accumulation in the paper machine front drying cylinders, mainly used in the first drying cylinders 1-3, to solve problems such as stickiness, accumulation, and difficult cleaning.

2.2. Suitable for high-speed paper machines and long-term production lines with continuous operation, high load, and high scraper pressure for high-quality cultural paper / packaging paper machines, reducing downtime and maintenance frequency.

2.3. Used for repairing and upgrading old cylinders with severe wear, corrosion, and scratches to replace old cylinders with repair instead of replacement, quickly restoring mirror-like and non-stick performance, with a higher cost performance than replacing new cylinders.

2.4. Suitable for special paper and high-end paper production lines with high requirements for smoothness, cleanliness, and glossiness of the paper, steadily improving the appearance and physical indicators of the paper.
