- The study on 50、40 radial series tire
Take 50、40 for representative in 435/50R19.5、445/50R22.5、455/40R22.5, it is the technological revolution in front edge in international tire market. At present only Michelin、BS and Goodyear have come to commercial sales. This type of tire is known as “twin-in-one”, which is to replace the twin rather than replace the vehicles. This tire has been used in Europe and North America. “Twin-in-one” saves cost 35% more than twin together. Mileage reaches 80% of the original. More importantly ,it improves safety.
- Research on long-distance and high-speed tire sold in domestic market
Through the adjustment in outline of the design、construction design、performance in formula, these measures improve the performance in long-distance durability in domestic market.
- The reverse design of the tire
Sailun makes analysis on the tires which have good reputation in the market. Through testing and study on the structure and formula, it proves reliable standards for tire design. In order to meet the requirement of target market and expand the company’s products share in the target market, the core of the technology is to improve the detection analysis measures.
In the aspect of structure, it is required to make analysis on the profile carve of model tire, material of cross-section and manufacturing process, finite element analysis on static mechanics, dynamic mechanics, and running performance; in the respect of formula, it requires the analysis on rubber mechanical properties, formula, raw material, consumption estimates and so on.. The analysis of means must achieve a higher accuracy degree and can provide a reliable basis for product development. Sailun uses actual test and finite element analysis to strengthen the mechanical performance research; physical and chemical performance analysis need studying higher accuracy test methods and make this method popular. The structures of outline analysis need to use advanced equipment to test analysis methods and improve the accuracy. From the above analysis, it puts forward reasonable proposals according to finite element analysis.
- Abrasion test methods on Vulcanized rubber
Through the establishment of abrasion analysis model under different degrees (cap and bead material), the design and actual effect have the consistency on the vulcanized rubber abrasion test methods.
Sailun also does research on abrasion theory under different formulations and different degrees, the relevant research between its result and actual effect under different abrasion test methods, and analysis on applicability of tread rubber. under different degrees,
- Mixing technology
There are two aspects for mixing technology. One is to improve the quality of mixing rubber, which is to improve the uniformity and dispersion. The other is to shorten the mixing time and improve productive efficiency. Mixing technique is studied from the two aspects to achieve the aim of being good and fast.
