The preparation method includes the following steps that 1, a main agent is prepared, a phenolic resin adhesive is used as a base material, a pH value is regulated to neutral, heating is performed to reach 55-65 DEG C, a proper amount of epoxy resin is added, constant temperature reaction is kept for 5-15 minutes, and then cooling is performed to room temperature; 2, a functional agent is prepared, a proper amount of propolis powder, flame retardant powder, organic bentonite and antioxidant are fully mixed evenly and are heated to 65-75 DEG C, and a stable molten viscous fluid is formed, and impurity particles are filtered out for usage; 3, a dry powder finished product of the preservative is prepared, wherein the main agent, the functional agent and a solvent are mixed evenly in proper proportion, and standing is performed for 8-12 hours after vacuum degassing; 4, the material obtained in the step 3 is subjected to vacuum solvent removal, and the dry powder finished product of the wood preservative is obtained through spray drying. The raw materials for the dry powder of the preservative is reasonable in selection and proper in compatibility. Compared with existing glue, the prepared dry powder of the preservative has excellent antibacterial, anticorrosive and flame-retardant properties.

A Dynamic Water Level Detector Based on Acoustic Attenuation Change
ActiveCN110375827BReal-time detectionQuick checkMachines/enginesLevel indicatorsReflected wavesEngineering
The invention discloses a dynamic water level detector based on sound wave attenuation variation. The structure of the dynamic water level detector comprises a signal conversion body, a signal transmitter, a digital display screen, a sound wave attenuation detecting device and an embedded protection tube, wherein the signal conversion body is of a cylindrical structure, the signal transmitter is arranged above the signal conversion body and is electrically connected with the same, the digital display screen is embedded on the front surface of the signal conversion body, and the sound wave attenuation detecting device is arranged below the signal conversion body and is electrically connected with the same. By means of the arranged sound wave attenuation detecting device, the dynamic water level detector detects the water level in real time by utilizing the principle of sound wave attenuation variation based on the water level, especially can quickly and precisely detect the dynamic water level since the dynamic water level is based on material reflection waves, is less susceptible to external conditions in detection, and is suitable for water level detection under various conditions.
