Now there is JJYMX-I (Fiber Oil Absorption Tester JT/T533-2004) in the market, which uses mineral oil such as silicone oil or kerosene to replace asphalt as the medium. A certain amount of mineral oil is fully stirred for 10 minutes, rested for 5 minutes, and then poured into the sample sieve. However, due to the use of mineral oils such as silicone oil and kerosene instead of asphalt, errors are prone to occur, and manual stirring is required, which is time-consuming and labor-intensive.
