How is rubber made?

The production of rubber products from natural rubber requires several different steps.

1. First, latex must be collected from rubber trees using a traditional process called rubber tapping.This involves making wide V-shaped cuts in the bark of the tree. As the latex drips out, it is collected in a cup.

2. The latex from many trees is then filtered, washed and reacted with acid to cause the rubber particles to coagulate (stick together).The rubber made in this way is pressed into thick sheets or thin sheets and then dried in preparation for the next stage of production. Plus, when it gets cold, it tends to get cold, smelly, sticky, sticky.
Further processing follows to turn it into a more versatile material.

3. A mechanical process first known as a "chewing machine" that uses mechanical rollers and pressure to "chew" raw rubber to make it softer, easier to handle, and stickier. After the rubber has been masticated, additional chemicals are mixed in to improve its properties (for example, to make it more wear-resistant).

4. Next, the rubber is flattened by rollers (a process called calendering), or extruded through specially shaped holes to make a hollow tube (a process called extrusion).

5. Finally, the rubber is vulcanized (cooked): sulfur is added and the rubber is heated to about 140°C (280°F) in an autoclave (an industrial pressure cooker).

As China Molded Diaphragm Manufacturers and OEM Fabric Reinforced Diaphragms Factory , The company not only has a complete set of rubber molding products such as kneading machine, open mill, filter machine, flat vulcanizing machine, etc., but also set up a mold processing and production center, which can customize various rubbers Diaphragm for customers.
The main products: rubber diaphragm obtained national patent in 1999, the service life of more than 200,0000 times. It has certain advantages in the development of special products such as silicone rubber, fluorine rubber, nitrile rubber, ethylene propylene rubber, butyl rubber and other products resistant to nuclear radiation, high temperature resistant oil, high temperature resistant steam and various chemical media.
