5 Answers to the Most Frequently Asked Questions about Rubber Calendering
by Avadhesh Sharma SEO Analyst1.Define Rubber Calendering.
The mechanical process by which rubber is converted into composite sheets of textiles, like cloth, fabric, and tire cord is called rubber calendaring. We are Rubber Calender Machine Manufacturers manufacturing high-quality products.
2.What Are The Types Of Rubber Calenders?
There are two or more rolls in rubber calendar machinery. These rolls revolve in opposite directions. Based on the number of rolls and the position of the rolls, rubber calenders can be classified into the following divisions:
2-Roll Horizontal Type Calender, 2-Roll Vertical Type Calendar, 2-Roll Tilted type calendar, 3-Roll Vertical Type Calendar, 3-Roll Offset Stack Calendar, 4-Roll Vertical Type Calendar, 4-Roll Offset Stack Calendar (L type), 4-Roll Offset Stack Calendar(S type) and 4-Roll Offset Stack Calendar(Z type).
3. What Are The Types Of Rubber Calendaring?
Calendering can be classified into two divisions based on what you are calendaring: steel cord calendaring and fabric calendaring.
Fabric Calendering: Softened rubber compound and Polyester go into your fabric calendering. The Fabric calendering process depends upon the tension, humidity, and temperature of the fabric cords. When fabric cords are calendared with the rubber compound, temperature and humidity play an important role in the process. Therefore, the fabric cord is kept in a room where humidity and temperature can be controlled.
Steel Cord Calendering: Steel cord calendering is used in the tire industry. Rubber doesn't adhere to bare steel. The steel cord is coated with a very thin layer of brass. The brass-coated steel wires are moisture sensitive. So, a humidity and temperature controlled environment are necessary for procurement, and shipment.
We are not the only manufacturer, but also Rubber Calender Machine Exporter.
4.Where Is the Rubber Calendering Process Applied?
Rubber calendering is adopted in the tire industry and plastic industry. The calendaring process leads to the production of two sheets- fabric inserted and unsupported. Calendared textiles are used in the tire industry for the casing, cap piles, and chafers. Calendared steel cord is used for belts.
5.What Is the Utility Of Rubber calendaring? And Which Rubber Calenders Will You Use?
The functions of rubber calendering are-
Skim Coating & Topping
Skim coating is the mechanical process by which rubber is coated on both sides of the fabric or steel cord. This operation supports the adhesion between the rubber and fabric or steel chords. Whether you will use a 3-Roll calender or 4-Roll calendar depends upon the process.
Frictioning
The process by which rubber is forced into the fabric weave is called fractioning. Good adhesiveness is added through fractioning. Install 3-Roll Calender where the middle-roll speed is higher than the top and bottom roll speed. Fractioning process doesn\'t use 4-Roll Calendar because here it is difficult to get the speed difference.
Rolling
When a hot rubber compound is passed through a 2-Roll Calendar, a rubber sheet of thickness 3-4 mm is obtained.
Profile calendaring and Embossing
After rolling, a hot rubber compound is pressed through a heavy engraved roll. This process offers your sheet a design look. The design of the engraved roll comes to your rubber sheets.
We, Rubber Calender Machine Supplier, supply products at a reasonable price.
Conclusion
Thus to conclude, we may say that rubber calendaring is a process through which rubber is pressed into textiles. To get high-quality products, these operations require critical checks.
