Natural rubber is made from latex, but where does the latex itself come from?

Rubber trees are tropical plants that require abundant rainfall throughout the year with little or no dry season. Periods of drought or temperatures below 65 degrees Fahrenheit will not necessarily kill the trees, but will reduce latex yield.

Many farmers grow rubber trees with oil palm, as they both require deep soil, stable high temperatures, and constant humidity. Both trees often require extensive deforestation to make room for crop growth.

 Rubber trees grow quickly and rarely exceed 25 meters in height. on plantations. Gardeners plant... Read more

Drying and rinsing fabrics. Fabrics used in the production of belts, sleeves and other products are coated with a rubber mixture.

If a relatively thick fabric, such as belting or chafer, is supplied to the calender for smearing, then the fabric must be preheated and dried. Heating the fabric makes it easier to lubricate, as the softened rubber compound penetrates the warm fabric more easily. By removing moisture, they improve the adhesion of the rubber mixture to the fabric and prevent delamination of the product, which is possible as a result of water vapor release during the vulcanization process. The fabrics are dried on... Read more

Laser machines for mold cleaning

Comments 0

General information

The most advanced and modern method of cleaning the shaping surfaces of molds is laser cleaning.

A high intensity laser beam is directed onto the surface to be cleaned. The influencing energy leads to an "explosion" of pollution, some of which evaporates, and the rest is dispersed. The wavelength of laser radiation is such that it is absorbed by polymeric materials but reflected by metal surfaces. As a result, there is no mechanical, chemical or thermal effect on the shaping mold.

Rubber open mixing mill. Description of the work process

Comments 0

 Open mixing mill - used for the production of rubber compounds. The rubber base material is mixed with several additives such as fillers, softeners, processing aids and colorants. The two rolls of a rolling mill rotate in the opposite direction. For mixing, one roller moves faster than the other, thereby creating friction. Thus, shear forces act on the rubber in the gap between the two rolls. What causes mixing.

In the manufacture of rubber products, rollers are of the utmost importance. Due to such methods as: mixing, sheeting, heating and many others, the quality of the final product depends.
