specific example 3
[0092] Preparation of Nanoscale Pearl Powder
[0093] 1. Liquid preparation:
[0094] 1. Dissolving:
[0095] Equipment used: heatable microwave multifunctional extraction tank
[0096] Add the prepared aqueous solution with a pH value of 3 into the extraction tank, completely immerse the raw materials, turn on the microwave generator, make it move at a speed of 2-3 billion times / second, and shake and dissolve until the raw materials are completely dissolved into a uniform liquid .
[0097] 2. Concentration:
[0098] Equipment used: low temperature decompression vacuum thin film evaporation concentration equipment
[0099] After transferring the completely dissolved liquid to about 100L in the evaporator, turn on the vacuum pump, start the vacuum system, open the steam valve, and start to concentrate. Control the steam flow rate to keep the temperature at 60±5°C. During the concentration process, the high-concentration and low-concentration ethanol are respectively sent ...
