Abstract:
Objective:To investigate the ultrasonic cleaning machine in the equipment derusting effect of.Methods: Rusty instrument as rust 600, were randomly divided into two groups, experimental group (n=305) and control group (n=295). The first device in according to 1:270 proportion of organic pollutants in multi enzyme cleaning solution good, the experimental group will rust instrument containing stainless steel basket, in according to the proportion of 1:7(water temperature is 60℃) ultrasonic cleaning machine solution rust agent by ultrasound in 10 minutes, with a soft brush to wash; the control group will instrument in the water temperature in 60℃, solution rust agent 1:7 mixing ratio, non constant temperature for 10 minutes using a soft bristle brush. Observe and record the two rust rust indicators, and analysis.Results: The naked eye visual two groups of instruments derusting pass rate was not statistically significant (P<0.05); microscopy (5 times the magnifying glass) experimental group equipment derusting pass rate was significantly higher than that of the control group, there were significant difference between two groups (P<0.001); total flexibility in experimental group was significantly better than the instruments the control group, there were significant difference between two groups (P<0.001).Conclusion: The rusty instrument in a constant temperature of 60℃ plus ultrasonic cleaning descaling effect, improves the equipment clean quality and overall flexibility.
