Product Description The rewinder is a device used to rewind large rolls of paper, film, or other materials into small rolls, and its working principle is as follows: Unwinding - The large roll of raw material is installed on the unwinding mechanism, which is usually equipped with a driving device and a braking device. The driving device provides the initial power to enable the large roll...

Working Principle When a polymer solution or melt is extruded from the spinneret, surface tension tends to form it into spherical droplets. A high voltage applied to the spinneret charges the surface of the droplets with the same polarity. When the electrostatic repulsion is strong enough to counteract the surface tension, the droplets form a conical shape (Taylor cone). As the voltage increases, ...

The following is a related introduction:   Features    Small footprint: Compact size, such as a desktop extruder, does not require too much space, and is easy to place in laboratories, small workshops and other places.    Easy ope...

The mixing mill, also known as the double-roll mixing mill, is one of the indispensable equipment in the rubber and plastics industry. It uses two relatively rotating rollers to shear, extrude and rub the materials, thereby achieving the process of mixing, plasticizing and dispersing the materials. It can be called the "alchemist" of the rubber and plastics industry. Working Principle The open mix...
