You can't bring acidic substances in the consumption process.
EDT detection (i.e. ceramic iodine detection).
PH detection method PH=5.
The best value of pottery is around 5.
Technological differences between ceramization and phosphating
Pottery can be absolutely at room temperature.
The surface adjustment was cancelled in the process of pottery making.
Less slag, less damage to equipment, and can prolong the service life of equipment.
The PH value of phosphating is 2-3; The PH value of pottery is 5.
Pottery can be recycled by backwater, which can save energy by about 30%.
In operation, only the PH value and glass transition point need to be tested: between 4.5 and 5.
The performance of pottery economy:
Ankang (no harm to the operator).
Storage (stacking can be stopped according to general chemical specifications).
There is no precipitation, no need to pour cans, and the consumption and addition of chemicals are very small.
The supply of washing water is reduced.
Emulsifier synthesis is simple, and oxygen consumption is reduced.
The cost of environmental protection is reduced, and there are no volatile organic compounds in ceramics, and the consumption is about one sixth of that of phosphating.
Low PH value, low corrosiveness to equipment and direct discharge.
