Precautions:
1. Replacement of passivated sand. When the passivation time of 400# sand tool is more than 20 minutes, the sand needs to be replaced or redeployed.
2. After the replacement of new sand, the passivation time of the first mode tool should be reduced. The passivation time cannot be reached once, but should be gradually extended to the range.
3, for the small number of sample knives, clamping should be separated from the isolation of clamping passivation.
4. The passivation time of the first mode tool at work should be reduced by 3 minutes every day. The passivation time should not be put into place once, and the passivation time should be gradually extended to the range.
