1. Oxidizing agent

Oxides must be in a molten state during the pre-piercing of the mandrel. Strict requirements in terms of force and other specifications apply.

1) The particle size of the descaling agent powder is generally required to be around 16 mesh.

2) The content of sodium stearate in the deoxidizer should be above 12% to ensure complete combustion within the capillary inner cavity.

3) Determine the dosing of the descaling agent based on the surface area of the capillary inner surface, typically 1.5-2.0g/dm². The dosage of descaling agent for capillaries of different diameters and lengths varies.
