Method for producing PVC-B (polyvinyl chloride-board) magnetic card surface course

Abstract

The invention relates to a technological process for producing a PVC magnetic card base material, and aims at providing a method for producing a PVC-B magnetic card surface course with stable performances such as high production efficiency, low cost, beautiful, fine and smooth surface stripes, controllable superthin material thickness and the like. The method for producing the PVC-B magnetic cardsurface course comprises the following production steps of: 1) metering and stirring raw materials, and feeding in an extruder; 2) putting the extruded materials in a two-roller area, and uniformly plastifying PVC powder; 3) entering a calendaring area, thus primarily forming the PVC powder in shape of a film; 4) entering a centrifuging stretching area, thus causing the formed PVC film to achievethe desired size; 5) entering a moulding knurling area, thus knurling and shaping the PVC film; 6) entering a cooling shaping area, thus cooling, flattening and shaping the PVC film; and 7) entering a shaping coiling area, thus coiling the formed PVC film.

Description

technical field [0001] The invention relates to a production process method of a PVC magnetic card base material. Background technique [0002] With the continuous advancement of science and technology, in the fields of telecommunications, banking, construction and labor security, involving telecommunications SIM cards, bank cards, public transportation, taxis, ferries, subways, tap water, gas, road and bridge tolls and parking management, publicity Printing supplies, advertising decoration supplies, etc. In recent years, with the continuous development of electronic technology, smart cards have become more and more widely used due to their safety, convenience, speed, small network investment, large capacity, and many functions. With the increasingly fierce competition in the industry, all card manufacturers are trying their best to find card base masks with stable performance, low price and beautiful surface texture. At present, the existing card-based mask PVC-B material ...

AI Technical Summary

Problems solved by technology

At present, the existing card-based mask PVC-B material production process is produced by sandblasting roller pressing, which has low production efficiency, high cost, unsightly and delicate surface texture, and unstable performance such as thickness control of ultra-thin materials.
