New tire technology "to force" energy saving

In recent years, the focus of China's tire industry development has shifted from the past “scale, quantity, and speed” to the rational development track characterized by “structure, quality, brand, and benefits”. Cai Weimin, secretary general of the tire division of China Rubber Industry Association, pointed out that if we want to go steadily faster on this road, and smoothly realize the industry's "turning mode" and "adjusting structure", we must put energy conservation and emission reduction and improve energy efficiency. The important position of the development of the industry.

The reporter learned from the tire branch of the China Rubber Industry Association that at present, energy saving and consumption reduction activities have been carried out in depth in the tire industry. Among them, the promotion and application of a batch of new technologies and new technologies have greatly reduced the energy consumption of the industrial added value of the tire industry.

According to reports, the rubber refining process is the most energy-intensive process for tire production, accounting for about 40% of the energy consumption of the entire tire production process. At present, a number of companies have successfully developed a "low-temperature one-time plastic compound" process for the rubber refining process. The new process reduces the intermediate transfer link of the rubber compound, thereby reducing the amount of space occupied by the rotary rubber compound and saving more than 1/2 of the floor space. The time for converting the raw material into the rubber compound is shortened from 12 hours to 30 minutes, which greatly saves time. The raw material costs; also achieved about 20% reduction in electricity consumption of tons of plastic, and more than 2 times the production efficiency.

In addition, the promotion of the "nitrogen vulcanization" process has become one of the major highlights of energy saving and emission reduction in the tire industry. In the past, tires used superheated water for heating during the vulcanization process. In fact, only a small portion of the heat was absorbed by the tire, and a large amount of hot water was inefficiently circulated. The use of nitrogen instead of hot water as the internal pressure medium for vulcanization is more advanced than the existing over-heat-water vulcanization process in terms of production efficiency, product quality, production cost, and energy consumption.

In addition to breakthroughs in new technology, Cai Weimin revealed that the next step will be to promote the energy conservation and consumption reduction activities of the industry in the following areas: First, to help companies establish correct concepts, and to realize energy saving and consumption reduction. The importance of “strengthening and expanding” for the enterprise; the second is to promote the successful experience and advanced technology of some companies; and the third is to jointly formulate tire process management regulations and green tire specifications to promote the development of green tire industrialization; It is to promote the coordinated development of related industries and the tire industry, support the development and application of new additives such as green additives, special carbon black, steel cords and gutta percha. The rubber equipment industry needs to understand the development needs of tire companies in a timely manner. And grasp the information dynamics of green tire manufacturing.

Tig Welding Torch have a type named Air Cooled Tig Welding Torch, it have the model number: WP-9 Tig Torch , WP-17 Tig Torch, WP-26 Tig Torch. When you use Tig welding torch, Tig Welding Nozzle will ejected Tungsten Inert Gas to produce a protective layer around the arc cut off the air in order to prevent its tungsten. Prevent its welding tungsten, pool and adjacent heat-affected zone, to obtain high-quality welds. We are a manufacturer in China main produce tig welding torches.
