Embodiment 1
[0029] -Place the calcium peroxide in a heated mixer.
[0030] Two-chitosan (CTS) film-forming material is nano-processed, the nano-chitosan suspension is prepared by ion gel method, an appropriate amount of CTS powder is weighed, and it is dissolved in 0.1M glacial acetic acid (HAC) solution at room temperature. Adjust the pH to 5 with NaOH and filter with a 0.45μm microporous membrane; dissolve sodium tripolyphosphate (TPP) in ultrapure water, adjust the pH of hydrochloric acid to 8, and filter with a 0.45μm microporous membrane. According to the experimental design, measure a certain amount of CTS solution into a 500ml three-necked flask, put it into a stirrer, place it on an electric stirrer with digital display speed, use a computer constant flow pump to control the dripping rate of the TPP solution, and drop it into In the three-necked flask containing the CTS solution, the dripping speed is 30 d / min, and the temperature change of the whole reaction process is controlled by...
