Rubber Roller For Printing Machine RYOBI 524 650 750 684 NBR Ink Ductor Roller

In the technical specifications of printing rubber rollers, surface roughness is an important performance to achieve the transfer of ink and plate lubricant by the rollers.

Ink rollers can be divided into three types: ink carrying, ink transmission, and plate support. Ink carrying rollers, also known as ink bucket rollers, are used
Extract a certain amount of ink from the ink hopper each time, and then transfer it to the ink transfer roller (also known as the uniform ink roller).

Generally speaking, a printing ink roller requires a surface roughness of 6-20 microns, while an alcohol water roller requires a surface roughness of 4-10 microns. Some printing machines grind the surface of the water roller finer to increase its water carrying capacity. For example, the surface roughness of the alcohol dampening water roller on the Komori printing machine is 2-6 microns.

The surface roughness of the glue roller plays a crucial role in printing. It not only accurately measures the ink and water transmitted, ensuring the stability of water and ink transmission, thereby ensuring the stability of printing colors, but also separates the ink in a uniform ink/water film form, ensuring continuous and smooth ink/fountain solution transmission, and forming ink/fountain solution accumulation to compensate for uneven defects caused by the transportation process.

The XINBAO high-end rubber roller has a bright color from the appearance, with a delicate and smooth surface of the colloid, and a strong bonding between the glue and the core. The size of the rubber roller does not change significantly at different temperatures and can adapt to high temperature and humidity environments or harsh cold and dry climate conditions.

The quality and condition of the rubber drum are crucial for these RYOBI printing machines to achieve sustained and stable high-quality printing. Regular cleaning and maintenance, as well as re wrapping when rubber is worn, are necessary maintenance measures.
