Sir
Indian Standard IS 3196 (Specification for LPG cylinders) recommends both Shot as well as Grit Blasting before Zinc Metallizing of LPG cylinders.
we would like to specify for Grit Blasting, Grit Size, Surface preparation specification, Idle time before metallizing and after shot blasting, importance for pretreatment etc.
Whether their will be practical test result difference
between
01. Shot and grit blasted & metallized surface.
02. for different Grit sized surface prepared & metallizing
03. different surface preparation grade
04. different idle time
05. between non pretreated and pretreated surface
please suggest how to go about it and how can we establish practically the above.
Regards
Sandeep
