Transformation and upgrading for rubber machinery industry in China is not fresh term already, in recent years, many rubber machinery enterprises are on the way of transformation and upgrading of bitter effort. Then, on the way of transformation and upgrading, enterprise encounter pressure, now got what grades? The future will be working in what direction? China chemical industry news reporter held on October 20 ~ 21, 2014, the annual meeting and product upgrading of China rubber machinery experience exchange meeting looking for answers, combing the rubber machinery industry in our country after entering phase transformation and upgrading of way and strategy.

Pressure: reversed transmission upgrades, tyre industry development needs equipment innovation

According to the China chemical equipment association of professional committee of the rubber machinery, honorary director of dong-ping li, China's tire industry after nearly 20 years of rapid development, into the critical period of transformation and upgrading, this will be reversed transmission rubber machinery products to accelerate the upgrade.

Dong-ping li told China chemical industry news reporter, tire structural overcapacity in China have been around for years, the tire is low homogeneity serious excess, but high-grade and green tire and larger development space. Rubber machinery from China chemical equipment association professional committee of statistical data can be seen, in 2014 our country all-steel tire can output will reach more than 180 million sets, semi-steel tire output can reach more than 600 million sets, and all-steel tire sales in China will be less than 110 million sets, semi-steel tire less than 400 million sets. With significantly lower capacity utilization, therefore, the next few years China's low-end tires will face to capacity of the pressure, high-grade and green tire gold could usher in a new development period.

In addition, dong-ping li pointed out that China's tire industry is relatively high, external dependency especially semisteel tyre dependent on exports more than 60% of the products, it also means that foreign anti-dumping increased risk. In the future, our country tire must resolve anti-dumping countervailing risks, such as reducing external dependency, so large enterprises will speed up to build a new factory or overseas acquisitions abroad tire company.

"More and more strict environmental protection policies also nots allow to ignore to the pressure of tire enterprises." Dong-ping li said that China tire enterprises in the aspect of energy conservation and environmental protection are mostly adopt the developing mode of "on board", quite a lot of tire enterprises although have passed the eia, but from the environment friendly enterprise gap is huge. Some of the location of the old tire enterprises is that the suburbs in the past, has now become the central area of a city. These companies face the task of transferring. As the new environmental policies introduced gradually, tire industry will become the behavior.

"From tire industry is undergoing changes in the above, we can see that this is not only the tire industry transformation and upgrading of pain, also bring the opportunity of rubber machinery industry. The future development of China's tire industry key instead of the expansion of the production quality, improve manufacturing tire grade and class as the mainstream, the need to improve the level of equipment precision and accordingly, promote the development of rubber machinery upgrading to the costliness. For example, three years ago, less than 20% of the total hydraulic vulcanizing machine in our country, but in recent years as the tire enterprises pay attention to the tire class, as well as the speeding up of the overseas layout, speeding up industrialization of the hydraulic vulcanizing machine, the current has reached 40% of the total hydraulic vulcanizer, the future will be to the international average level, which is 60%; another example, a high proportion of white carbon black used for rubber compound extrusion green tire tread, extruder screw and head heat production, low flow section to increase the conducting electrostatic rubber compound, all contact with the surface of the rubber should have good acid corrosion performance. All in all, the new technology drives the process change, all need tire equipment innovation, to meet the requirements of the new process." Dong-ping li said.

In addition to the development of tire industry reversed transmission speed upgrade, rubber machinery products machinery industry's own development needs and requirements are put forward for rubber machinery.

Data show that China's rubber machinery industry for many years high speed development, the sales revenue from $2001 in 2.2 billion to $2013, 2013 yuan, the compound annual growth rate of 16%. Especially after 2013 and 2014 tire blowout expansion, China's rubber machinery production capacity is increased quickly, rubber machinery has already entered a buyer's market. In the industry point of view, the next few years China's less demand for conventional rubber machinery to a big probability event, conventional rubber machinery demand could face years of recession.

At the same time, the development of the integrated automation system also requires machinery industry toward safety, intelligent direction. This not only save labor costs, the most important removal of manual intervention process, reduce error accumulation in the process, to prevent and reduce the process error, reduce mass accidents and so on comprehensive benefit loss caused by the process factors, at the same time improve production capacity.

Achievement: reduce the energy consumption and improve the advanced equipment market share

Many rubber machinery enterprises have pressure to just have power, has been in the process of transformation and upgrading of the achievements.

For example, a method of continuous mixing technology and equipment at low temperature rubber refining industry in our country the promotion, a wheel industry made a breakthrough in energy conservation in China. According to the China chemical industry news reporter understanding, compared to before the process, a continuous mixing process at low temperature reduces the intermediate transfer rubber band, greatly save the mixing time, mixing rubber raw materials into a shorter time from 12 hours to 30 minutes, reduce the cost of raw material utilization, and since there is only a mixer heating process, most of rubber mixing on the mixing machine mixing, low temperature greatly reduces the energy consumption. The technology has been in guizhou tyre, triangle tyre industry leading enterprises in the industrial success, and is promoted in China tire enterprises. Triangle tyre, the wheel, and guizhou tyre after the actual use is introduced, such as glue can reduce 10% ~ 20% power consumption per ton. Especially in the triangle tyre in the workshop, mixing rubber consumption per ton, 870 kg BiaoMei, while the industry average to 1100 kg BiaoMei. And because of the low temperature mixing process is beneficial to improve the dispersion of carbon black, greatly improve the physical and mechanical properties of the rubber.
