On use.
China is iron easy-open end big producer, and the synthesis annual output of various cap-type has reached about 5,000,000,000, and easy-open end is crucial
Feature is exactly to be disappeared in this way at the inner ring edge of lid using the indentation for generating about 0.1mm on iron-based material of the high-precision icking tool by 0.2mm
Expense person pulls cover plate to open lid along indentation to achieve the purpose that facilitate unlatching after passing through pull ring breakdown, but indentation can destroy
Original capping coating, the filled canned pack of easy-open end most of in actual use need to by thermophilic digestion, if at indentation without
Protective coating meeting corrosion need to carry out sprayed protection to knurled portion to lose use value.Knurled portion carries out
Spraying needs rapid curing, and after boiling in 121 DEG C/60 minutes, coating must not whiten, not fall off.Because easy-open end is digested
Air pressure will lead to closure deformation in tank in journey, therefore institute's spray coating must have good adhesive force and flexibility to substrate, cannot
Because when lid temperature distortion and substrate removing loses protection effect.The main two-component curing system for using colloidal sol type at present,
And it may relate to the crosslinking composition of isocyanates.
