  • Publication number: 20240084114
    Abstract: A method for preparing a rubber for an elastomer of a flexible joint, includes: weighing hydrogenated nitrile raw rubber, a silica reinforcing agent, aramid fiber pulp, carbon black, liquid nitrile rubber, zinc oxide, stearic acid, an antioxidant, and a peroxide crosslinking agent; plasticating the hydrogenated nitrile raw rubber in a first internal mixer at 125-135° C., collecting a resulting product and cooling, to yield a plasticized rubber; preheating the liquid nitrile rubber; adding the plasticized rubber to a second internal mixer, further adding the aramid fiber pulp, the zinc oxide, the stearic acid, and the antioxidant to the second internal mixer for first mixing; adding the carbon black to the second internal mixer for second mixing; adding the silica reinforcing agent and the preheated liquid nitrile rubber to the second internal mixer for third mixing; and collecting a discharged product when a temperature of the second internal mixer is 140° C.

  • Publication number: 20220417713
    Abstract: The building stress balance monitoring system of the passive sensor network, relating to the technical field of information, and aiming to solve the problem of making the pressure sensor easier to be charged in building stress monitoring. The system includes plurality of nodes arranged in the same building surface of the building or arranged in the supporting surface of the bridge; each node mainly consists of the pressure sensor module, the radio frequency signal acquisition module, and the network module; the sensing surface of the pressure sensing module acquires building pressure information and transmits same to the pressure sensor module; the pressure sensor module receives electric energy provided by the radio frequency signal acquisition module, and converts the pressure information into data, which can be uploaded to the network through the network module. The effect of making the pressure sensor easier to be charged is achieved.
