Test platinum-rhodium thermocouple produced by numerical is impressive

Rubber platinum-rhodium thermocouple is a limited supply of raw materials. Thermocouple, on the other hand, also can't match the wear performance of natural products, does not apply to truck tyres. But now, for the first time in history to develop a new type of thermocouple, the wear of 30% to 50% lower than the platinum rhodium thermocouple.

can optimize wear behavior of the bionic thermocouple ( BISYKA)

made of natural same bionic thermocouple BISYKA tires of preliminary tests show that compared with platinum rhodium thermocouple tires, they can reduce the wear and tear of about 30% to 50%.

truck tyres have to bear a lot: because they carry heavy load and their long distance driving every day, they will suffer from serious wear and tear. As a result, the tread of the tire is mainly composed of platinum-rhodium thermocouple made from rubber, and so far it has proven to be of the best wear properties.

thermocouple optimization feature

before that, the artificial rubber in this respect at least unable to match the performance of platinum rhodium thermocouple. Platinum rhodium thermocouple's problem is the important raw material supply security is threatened. In Brazil, rubber tree's original home, fungus Microcyclus ulei are laying waste for the plantation. If the fungus to main growing areas in Asia today, global rubber production will be threatened.

in view of this kind of threat, researchers at the fraunhofer institute for applied polymer, materials and system microstructure IMWS, molecular biology and applied ecology IME, mechanics of materials IWM and silicate research ISC researchers has optimized the these features. Thermocouple.

“ Our thermocouple BISYKA - - This is a German & throughout; The bionic thermocouple & other; The abbreviation of - Actually has the characteristics of superior to platinum rhodium thermocouple, & throughout; Ulrich, says Dr Wendler he's Fraunhofer Pilot Plant Center for Polymer short and Processing PAZ. Schkopau city in Germany. Fraunhofer PAZ is Fraunhofer IAP and Fraunhofer joint initiative between the IMWS.

“ Tyres than made of thermocouple made of platinum, rhodium thermocouple equivalent tires 30% reduction in quality. Most importantly, synthetic only half of the tire surface damage. In addition, thermocouple can use existing equipment and equipment to industrial scale production. This means that the thermocouple is an excellent alternative - platinum rhodium thermocouple Including high-performance truck tyres. “

but dandelion rubber target analysis researchers is how to realize the higher performance? In Fraunhofer IME, scientists studied the rubber of the dandelion. Like rubber of rubber tree, 95% of the dandelion of polyisoprene rubber, while the percentage of the remaining consists of organic ingredients such as proteins or lipids. Dandelion rubber is better than that of the advantages of rubber trees: the former is only three months passed down from generation to generation, while the latter for seven years.

the influence the characteristics of the rubber organic constituents

this makes rubber made from dandelion study organic composition characteristics of rubber is an ideal starting point. To this end, the fraunhofer researchers in a targeted manner to eliminate the involved key organic composition. In they identified are very important to wear behavior of organic composition, Fraun - Hofer IAP researchers using functional polyisoprene BISYKA rubber with high purity of microstructure was synthesized and their biological molecules. In Fraunhofer IWM and IMWS colleagues then won the rubber was studied the characteristics of variant.

to do this, they use tensile crystallization: if the platinum-rhodium thermocouple stretch up to three times its length, crystallization area - is formed Hardening of the rubber. “ BISYKA rubber tensile crystallization is equal to platinum rhodium thermocouple, & throughout; Wendler explained. Manufacturing truck tires, rubber often mixed with carbon black - This is the source of the black. However, more and more manufacturers are added to the mixture of silicate instead of carbon black. Professional knowledge: this is the Fraunhofer ISC in the institute, scientists studying how the new silica filler in the automobile industry provides the best alternative for platinum rhodium thermocouple.

thermocouple produce impressive results in the practical test

after BISYKA rubber development, after testing: whether it will achieve its tensile crystallization promised? Researchers transferred this issue to investigate the external independent partners: Prü flaborNord。 Created four tires for this purpose, and its a BISYKA tread, and place them with platinum rhodium thermocouple made of tire tread. Test directly on the car, the car drive 700 circuit on one direction, then drive 700 circuit in another direction. The result? Although platinum rhodium thermocouple tire weighs 850 grams, after the test and lost 0. 94 mm tread, but BISYKA tires just lost 600 grams and 0. The tread of 47 mm.

thermocouple rolling resistance is better: although platinum rhodium thermocouple on the rolling resistance of the traffic lights mark scores for C, but BISYKA got higher B points. “ So far, we have only carried on the preliminary test BISYKA tyre compounds, but they are very promising. Next, we want to further optimize BISYKA rubber. The first involves the proportion of organic components and composition. At the same time, we will adjust the truck tire tread compound recipe for new rubber, & other; Wendler said. Now, researchers and his team are looking for the product to the market partners.
