Tire reclaimed rubber is used as the lowest price and largest amount of reclaimed rubber. It is widely used in the production of various reclaimed rubber products, such as pads in daily life, hoses in industrial fields, automobile tires in the automotive industry, etc. Among them are molded rubber products and extruded rubber products. So, what's the difference among molded rubber products and extruded rubber products produced from tire reclaimed rubber, and how do you choose the tire reclaimed rubber that is suitable for producing different molded rubber products and extruded rubber products?
First, let's take a look at the difference among molded rubber products and extruded rubber products.
In daily life, irregular/discontinuous rubber products such as rubber sheets, rubber pads, and rubber rings are molded rubber products. The products are vulcanized by the corresponding molds. These products are characterized by their accurate shape and texture. Compact, simple production process, can achieve mechanization and automated production, high efficiency, low cost; relatively speaking, extruded rubber products can be continuously produced, complex cross-section shape rubber products, common, such as hose, cable jacket, etc. In the extruder, the process is simple and continuous production can be achieved.
In actual production, when using tire reclaimed rubber to produce molded rubber products, the fineness requirements for reclaimed rubber products are not very high, generally 30-40-ton tire reclaimed rubber can meet the fineness of raw rubber for molded rubber products. However, when tire reclaimed rubber is used to produce molded rubber products that require high surface brightness, it is necessary to choose a product with more than 60 mesh.
Extrusion rubber products are carried out in the extruder. The fineness of the tire reclaimed rubber is very high. Generally, the rubber reclaimed rubber of 60 mesh or more can produce extruded rubber products. The thinner the extruded rubber products are, the more The fineness of the tire reclaimed rubber is required to be higher. For example, a rubber hose with a wall thickness of 2mm or less must use a tire reclaimed rubber with an 80 mesh or more. In fact, whether it is a molded rubber product or an extruded rubber product, only a suitable rubber reclaimed rubber can be used to produce good rubber products. In addition to the fineness, the strength and environmental protection standards of the reclaimed rubber must also be considered.
