UHMWPE, or ultra-high molecular weight polyethylene, is a type of plastic with many advantages over other materials. It is extremely strong, durable, resistant to abrasion, corrosion, and chemicals, and has a low coefficient of friction. These properties make UHMWPE an ideal material for various applications, especially in the paper manufacturing industry.
What is a suction box and why is it important for paper making?
One of the most important components of paper making is the suction box plate and it always is made of UHMWPE material, which is a device that removes water from the wet paper web as it passes over it. The suction box consists of a perforated cover that creates a vacuum and a box that collects the water. The suction box plays a vital role in determining the quality and properties of the paper, such as its strength, smoothness, and thickness.
What are the drawbacks of metal and ceramic suction boxes?
Traditionally, suction boxes were made of metal or ceramic materials, which had some drawbacks. Metal suction boxes were prone to rusting and corrosion, which could affect the paper quality and cause maintenance problems. Ceramic suction boxes were brittle and fragile, which could lead to cracks and breakages. Moreover, both metal and ceramic suction boxes had high friction coefficients, which could cause wear and tear on the paper web and reduce its efficiency.
What are the benefits of UHMWPE suction boxes?
To overcome these challenges, UHMWPE suction boxes were developed as an alternative solution. UHMWPE suction boxes have many benefits over metal and ceramic ones, such as:
- No adhesion: UHMWPE has a very smooth surface that prevents adhesion or sticking of the paper web or the pulp fibers. This reduces the risk of paper breaks and improves the paper quality.
- Excellent chemical resistance: UHMWPE is resistant to various chemicals that are used in the paper-making process, such as sodium hydroxide, sodium sulfide, bleaching agents, and sizing agents. This prevents any chemical reactions or corrosion that could damage the suction box or the paper web.
- Low coefficient of friction: UHMWPE has a very low friction coefficient, which reduces the drag and resistance on the paper web as it passes over the suction box. This increases the speed and efficiency of the paper-making process and reduces energy consumption.
- High impact strength: UHMWPE has a very high impact strength, which makes it able to withstand high pressures and stresses without cracking or breaking. This increases the durability and reliability of the suction box and reduces maintenance costs.
- Light weight: UHMWPE is much lighter than metal or ceramic materials, which makes it easier to handle and install. This also reduces the load on the paper machine and improves its performance.
How are UHMWPE suction boxes used in different types of paper machines?
UHMWPE suction boxes are widely used in various types of paper machines, such as Fourdrinier machines, twin-wire machines, cylinder machines, and tissue machines. They can be customized according to different specifications and requirements, such as size, shape, color, hole pattern, slot width, etc.
