The drying cylinder is one of the main components of the shrinking machine. It mainly uses heating steam to dry the fabric, and the steam main pipe leads into the hollow column of the dryer or the steam pipe beside the rectangular column of the trough. Only drying cylinder. So, what are the characteristics of the drying cylinder in the pre-shrinking machine?
The surface of the cylinder of the preshrinker is coated with a Teflon coating, so it has good tackiness. Almost all substances do not adhere to the Teflon coating. Even very thin films show very Good non-adhesive properties, so there is a concern that the material and the drying cylinder will stick together during the pre-shrinking process.
Secondly, the Teflon coating used in pre-shrinking drying cylinders has excellent heat resistance and low temperature resistance, can withstand high temperatures up to 300°C in a short time, and can be used continuously between 240°C~260°C, with remarkable thermal stability. Sex, it can work at freezing temperatures without embrittlement and does not melt at high temperatures.
At the same time, the friction coefficient of the surface of the pre-shrinking cylinder is also low, and the friction coefficient changes when the load slides, but the value is only between 0.05-0.15. In addition, it is not easy to stick to the solution during the production operation. For example, if a small amount of dirt adheres to it, it can be wiped out with a simple wipe. Shorter downtime saves man-hours and improves work efficiency.
When the pre-shrink machine is running under high load conditions, the drying cylinder can also maintain excellent wear resistance, and at the same time, it is almost free of chemicals, and can protect parts from any kind of chemical corrosion, thereby prolonging the service life of the entire device. http://www.haida-textile.com/
