"ALUMINUM LOADING OF REINFORCEMENT, PROCESSES FOR THE REINFORCEMENT OF A COMPOSITION OF DIETIC RUBBER AND MANUFACTURING OF AN ALUMINUM LOAD, USE OF AN ALUMINUM LOAD, ROSEMARY RUBBER COMPOSITION, AGRICULTURAL, WHEEL, WHEEL, WEATHER, UTILITY PNEUMATIC, DEVICE AND PROCESS FOR MEASURING THE SPEED OF DISAGLOMERATION TO ULTRASOUNDS OF A LOAD THAT IS PRESENTED IN THE FORM OF PARTICLE AGGLOMERATES, AND THE USE OF A MEASUREMENT PROCESS OR OF A MEASUREMENT DEVICE ". Aluminum reinforcing filler, usable for the reinforcement of dienic rubber compositions, consisting of an aluminum oxide-hydroxide responding, to impurities and water of subsequent hydration, to the general formula (a and b real numbers): (I) A1 (OH) ~ a ~ O ~ b ~. with: 0 <a <243> 3 and b = (3-a) / 2, whose specific BET surface is between 30 and 400m² / g, the average size (mass) of particles d ~ w ~ is between 20 and 400 nm, and the noted de-agglomeration speed <244> measured in the said ultrasound de-agglomeration thesis, with 100% power from a 600-watt ultrasonic probe, is greater than 5.10 ^ -3 ^ Ám ^ -1 ^ / s . Rubber composition usable for the manufacture of tires comprising, as a reinforcement load, said aluminous load. |
