What is the use of calender roller ratio?

Friends who know the calender should all know that the calender has a data speed ratio, but the speed is exactly what the use will affect which parts of the production process, I believe many of my friends are not yet very understanding of today, For everyone a brief introduction about the calender speed ratio knowledge, I hope for your help
Common speed ratio
1, In order to exclude the bubble in the rubber, the general feeding roller has a speed ratio, often 1: 1.1 ~ 1: 1.5, our country to use more than 1: 1.1 ~ 1: 1.4. Soft small value to take.
2, For wiping operation, in order to make the material infiltrate into the textile, the wiping roller requires speed ratio. The bigger the speed ratio is, the bigger the shearing force is and the better the rubber erasing effect is. However, the speed ratio is too big to damage the strength of the textile and it is easy to scorch the rubber material. The speed ratio is too small, the penetration of rubber is poor. The general use of 1: 1.2 ~ 1: 1.5, our country to use more than 1: 1.4 ~ 1: 1.5.
3, For the tableting, laminating, plastic and other operations, mainly due to the requirements of squeezing pressure, it is generally used isal calendar, speed ratio of 1: 1.
4, In the choice of roller speed factors to be considered
Roller speed directly affects the calender's power consumption and production capacity. The greater the roll speed, the higher the power and output, the higher the level of mechanization and automation of the calender. Therefore, the choice of roller speed to consider:
1, Rolling production process requirements;
2, Calender manufacturing level and quality;
3, Rolling unit automation level.
4, The production is stable;
Roller speed marks the advanced level of rolling unit. The speed ratio of free adjustment in a calender to complete a variety of jobs, which makes the machine more adaptability, Division I customized all types of precision rolling machine equipment, PLC man-machine interface to make the operation easier, independent speed ratio adjustment Equipments, integrated body allows you to produce more stable and efficient, high-precision combination of design, to ensure product accuracy.
