High quality paper making machine parts sizing machine

  The sizing machine in a paper - making machine is a device used to apply sizing agents to the surface of paper or paperboard, which aims to enhance the resistance of paper and paperboard to the penetration and diffusion of aqueous solutions, as well as improve their smoothness, hydrophobicity, and printing adaptability. There are different types of sizing machines. For example, the film - transfer sizing machine is a pre - metering - roll - type sizing equipment. The sizing liquid is pre - metered onto the sizing roll through a metering component to form a uniform sizing film. When the paper web passes through the nip of the sizing roll, the sizing film is transferred from the sizing roll to the paper web to complete the sizing process. Due to the pre - metering, the sizing film is thin and uniform. When the paper web passes through the nip, it is subjected to less impact from the sizing liquid, and the amount of sizing liquid that penetrates into the paper web is limited, resulting…
