Example Embodiment

[0031] Example one:

[0032] A production process of polymer composite galvanized sheet includes the following steps:

[0033] 1) Place the galvanized sheet roll on the fixed frame of the unwinding equipment;

[0034] 2) Place one end of the galvanized sheet roll on the splicing machine, and then start the splicing machine to make a preliminary connection between the galvanized sheet and the polymer film;

[0035] 3) Then let the spliced ​​galvanized sheet and polymer film pass through a rectifier for correction;

[0036] 4) The rectified galvanized sheet and polymer film are preheated by a preheating machine, and the preheating temperature is controlled at 130°C;

[0037] 5) Heat the preheated galvanized sheet and polymer film through a heating furnace, and the temperature of the heating furnace is controlled at 300°C;

[0038] 6) Put the heated galvanized sheet and polymer film into the overheating laminating machine for thermal composite filming, and the temperature of the thermal comp...

Abstract

The invention discloses a production process for a polymer composite galvanized sheet. The process comprises the following steps: 1) placing a galvanized sheet winding roller on a fixing frame of unwinding equipment; 2) placing one end of the galvanized sheet winding roller on a splicing machine; 3) performing correction on the spliced galvanized sheet and a polymer film by a deviation correctingdevice; 4) performing pre-heating on the corrected galvanized sheet and polymer film by a pre-heating machine; 5) performing heating on the pre-heat galvanized sheet and polymer film by a heating furnace; 6) performing thermal compounding laminating on the heated galvanized sheet and polymer film by a thermal compounding machine; 7) performing embossing on the film surface of the laminated galvanized sheet by an embossing machine; 8) cooling the embossed and shaped galvanized sheet by clean water, and removing moisture of the galvanized sheet in a fan zone; and 9) sending the dried galvanizedsheet to an edge trimming machine, and performing edge trimming. The process disclosed by the invention has the advantages of reducing a falling rate of the polymer film and enabling misalignment of ahot composite film to be not easy to generate.

Description

technical field [0001] The invention relates to a production process of a polymer composite galvanized sheet, which is applied in the field of galvanized sheet production. Background technique [0002] Galvanized sheet refers to the steel plate coated with a layer of zinc on the surface. Galvanized is an economical and effective anti-rust method that is often used. About half of the zinc production in the world is used in this process. [0003] In the use of some specific products, it is necessary to apply a composite film to the galvanized sheet, and to paste a polymer film on the galvanized sheet, which can effectively improve the service life of the galvanized sheet and prevent the galvanized sheet from being corroded. The technology of sticking polymer film on galvanized sheet is not mature, and the polymer film thermally laminated on galvanized sheet is easy to fall off, and the existing thermal lamination film sticking device is prone to the problem of film deviation, ...
