Need some advice. rust removal chemical
hi guys, i need some advice on my personal project.
- i am planning on building a machine that clean and remove rust from a motorcycle engine block.
- this machine using the same method like sand blasting to remove paint but instead of using sand, this machine using a rust removal chemical. the idea is so it can clean the internal of the engine block.
- imagine the machine is like a square box that divide into two section, above section is a fully closed section. the machine is consist of a tank, pump motor, few nozzle, a spinning table powered by a power window motor. the idea is to pump the chemical from a tank at the below section to shoot the engine block on a spinning table with high pressure from a nozzle at the above section and this will be the cycle of the machine.
- the problem is, the chemical will produce foam. i have experimented on using other chemical as well but will still produce a lot of foam. can u guys help me on how to prevent the foam from forming?
thank you for any advice you guys could give me.
