Rubber Rheometer/Rotorless Rheometer

Product Description

Product Description
ApplicationHY3310 Rubber Rotorless Rheometer is used to determine the vulcanization characteristics of a rubber compound. It can dynamically display temperature curve and curve of shear modulus- vulcanization time under set temperature and pressure. It consists of main machine, temperature determination and control system, sensor, computer, data collector, printer and electrical components.Features1. It is a necessary equipment to optimize formula, make production parameters and improve quality of rubber product 2. High accuracy, good repeatability and stability, convenient and practical, it can precisely find out the best vulcanizing time3. Imported intelligent digital meter, easy to adjust and set, large temperature control range, high accuracy4. Computer control, collect, save and save test data, printout test result5. Test curves can be magnified and compared 6. Windows operation platform to make date processing more accurate. Specification ModelHY3310-IITemperature rangeRT~200℃Temperature accuracy of die cavity≤±0.1℃Resolution of temperature display0.1℃Heating time≤10minHeating speedabout 25℃/minTemperature compensation rateWithin 15mins to reach to set temperature after putting the specimen into die cavityTorque range0~300dNmTorque resolution0.01dNmThe frequency of oscillation1.67HZ(100rpm)The angle of oscillation±1°, ±3°, (±0.5°optional)Power supplyAC220V 50HzDimension625mm×600mm×1250mmWeight130kg Testing Result:ML : Min. torque (dNm)—The testing value of sample’s vulcanization characteristics (viscosity) before vulcanization. MH : Max. torque (dNm)—The testing value of sample’s shearing modulus or rigidity. Including even torque, max. torque for returning curve, and the max. torque during the specific period of no even or returning curve happens. Ts1 (min)—The time when the torque increases to ML +1dNm, the angle of oscillation is 0.5° or 1°. This figure shows the scorch time. Ts2 (min)—The relative time when the torque increases to ML +2dNm, the angle of oscillation is 3°. This figure shows the scorch time. T10 (min)—The time when the torque increases to ML + 10 (MH - ML ) / 100dNm. This figure shows the scorch time. T30 (min)—The time when the torque increases to ML + 30 (MH - ML ) / 100dNm. T60 (min)—The time when the torque increases to ML + 60 (MH - ML) / 100dNm. T90 (min)—The time when the torque increases to ML +90 (MH - ML) / 100dNm. This figure shows the optimum cure time. Ti (min)—The time when the torque increases to ML + i (MH - ML ) / 100dNm. Vc—Vulcanizing speed index. Vc =100/(T90 – Tsi)
