Abstract
The invention discloses a process for manufacturing acid- and sulfur-resistant snap lids, which comprises the following steps of: selecting an aluminum plate, coating a colorless epoxy organic silicon coating on the surface of the plate on which the outer surfaces of the snap lids are formed, drying the coating, coating a fluorocarbon coating on the other surface of the plate, and drying; and sheeting the plate, rounding edges, molding, forming large and small bubbles, nicking, protecting the edges, nailing rings, and injecting glue to form the finished snap lids. The snap lids manufactured by the process are acid and sulfur resistant, and can be used for packaging high-acid and high-sulfur foods or drinks.
Description
Technical field
The present invention relates to a kind of manufacture craft of the acidproof easy-open lid of anti-sulphur.
Background technology
Easy-open lid is as common a kind of packing assembly, be widely used in the milk powder packing, on chickens' extract packing and other some packaging materials for food, some Foods or drinks has stronger acidity or sulfur-bearing, general easy-open lid can be corroded, if the time of storage is longer, and easy-open lid surface even crackle occurs or the crack causes leak tightness to go wrong, thereby the food of dress or beverage are rotten in making, cause commodity quality problems to occur.
Summary of the invention
The manufacture craft that the purpose of this invention is to provide a kind of acidproof easy-open lid of anti-sulphur.
The technical solution used in the present invention is:
A kind of manufacture craft of the acidproof easy-open lid of anti-sulphur, it may further comprise the steps:
1) selects aluminium plate, apply colourless epoxy organosilicon coating and oven dry, in another side coating fluorocarbon coating and oven dry at the sheet material face that forms the easy-open lid outside face;
2) sheet material is hacked, round edge, moulding, the big vesicle of formation, indentation, guarantor limit, nail ring, injecting glue, formation finished product easy-open lid.
The thickness of described aluminium plate is 0.2-0.26mm.
Described colourless epoxy organosilicon coating is a kind of among FTH128, the FH131.
Described fluorocarbon resin coating is a kind of among Asdon54742, the Duranar.
Colourless epoxy organosilicon coating applied thickness is 1-2g/m2.
The fluorocarbon coating applied thickness is 2-3g/m2.
The draw ring that the nail ring is used is the 300# draw ring.
The invention has the beneficial effects as follows: the anti-sulphur of easy-open lid that is made with this technology is acidproof, can be used for encapsulating peracid high-sulfur Foods or drinks.
The specific embodiment
1) selects aluminium plate, apply a kind of among colourless epoxy organosilicon coating FTH128, the FH131, oven dry, a kind of in another side coating fluorocarbon coating Asdon54742, Duranar, oven dry at the sheet material face that forms the easy-open lid outside face; Colourless epoxy organosilicon coating applied thickness is 1-2g/m2, and the fluorocarbon coating applied thickness is 2-3g/m2;
2) sheet material is hacked, round edge, moulding, the big vesicle of formation, indentation, guarantor limit, nail ring, injecting glue, formation finished product easy-open lid.
Selected aluminium plate is the aluminium plate of 3104 H18, H19.The outside face of easy-open lid is coated with resistant to elevated temperatures colourless epoxy organosilicon coating, and inside face is a fluorocarbon coating, and the packing that contain these goods can acidproof anti-sulphur.
Under 121 ℃, the citric acid of use 2% soaked these goods 30 minutes, and coating does not come off, and illustrates that it has acidproof preferably sulfur tolerance.
