Problems solved by technology

Due to the low melting point of hot-melt adhesives such as acrylic resins, products compounded in this way cannot be sterilized by high-temperature cooking, and acrylic resins themselves also have certain toxicity, so they cannot be used in packaging cans such as beverages, juices, and tomato sauces. use

Embodiment Construction

[0058] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0059] figure 1 It is a schematic diagram of a production line of an embodiment of the coated iron processing technology of the present invention.

[0060] The whole process flow is divided into cleaning and drying stage, preheating stage, lamination stage, cooling stage and auxiliary stage, etc. The entire technological process and steps of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0061]The steel plate to be processed is cold-rolled thin coiled steel plate (chrome-plated iron) with chrome-plated surface, and the plastic film used for compounding can be PP plastic (polypropylene) or PET plastic (polyester).

[0062] The first is the cleaning and drying stage. Such as figure 1 Among them, the cold-rolled thin coiled steel plate (chrome-plated iron) that needs to be processed is u...

Abstract

The invention provides a technology for processing film-coated iron. The technology for processing film-coated iron comprises the following steps that a cold-rolled thin collared steel plate (chrome-coated iron) subjected to surface chrome coating treatment is unreeled by an unreeling machine, then is cleaned up, is dried and is put into a preheating device for preheating; and the preheated steel plate is treated by a film pressing device so that the preheated steel plate and a plastic film are compounded by heating. The invention also provides a device for processing film-coated iron. The technology and the device for processing film-coated iron have the advantages that high efficiency, environmentally friendly and low-cost steel plate surface coating is realized; a production process is environmentally friendly; a product has good impact resistance and corrosion resistance; toxic low-molecular residues are not produced; and the technology and the device accord with a modern industrial large-scale production idea of low carbon and environmental protection.

Description

technical field [0001] The invention relates to a process and equipment for producing coated iron, in particular to a process and equipment for thermally compounding chrome-plated iron and plastic film through high temperature. Background technique [0002] Metal packaging is an important part of China's packaging industry. Its output value accounts for about 10% of the total output value of China's packaging industry. It mainly provides packaging services for industries such as food, canned food, beverages, oils, chemicals, pharmaceuticals, stationery and cosmetics. In terms of product form, there are mainly various beverage cans, food packaging cans / boxes, metal aerosol cans, gift cans, chemical material cans / barrels, etc. In terms of packaging materials, there are mainly aluminum cans and iron cans. [0003] At present, in our country, most food packaging metal cans are made of paint cans. The paint used on the inner surface of the cans, that is, the surface that directl...
