Problems solved by technology

The above method reduces the probability of shrinkage and deformation of the steel door after foaming, but to a very limited extent
In addition, thickening the board and pasting cushioning and isolation materials will lead to a substantial increase in the cost of the door body, which cannot effectively improve the market competitiveness of the product

Abstract

The invention discloses a refrigerator door body with anti-foaming shrinkage deformation, and relates to the technical field of refrigerator door bodies. The invention includes that the refrigerator door body is formed by bending a steel plate shell; the surface of the refrigerator door body is engraved with micro-holes; the outer surface of the refrigerator door is pasted with a breathable film; By engraving micro-holes on the surface of the refrigerator door body, the invention ensures that the gas generated during the foaming process of the refrigerator door body is smoothly discharged through the micro-holes, effectively avoids quality defects such as gas accumulation and empty material during the foaming process, and improves the door body. Surface roughness.

Description

technical field [0001] The invention belongs to the technical field of refrigerator doors, and in particular relates to a refrigerator door capable of preventing foaming, shrinkage and deformation. Background technique [0002] Among the refrigerator panels, steel doors account for an increasing proportion, especially for export refrigerators, which are dominated by steel doors. The ever-changing steel plate surface treatment technology has enriched the appearance of steel plate refrigerators and improved the product grade. However, after the steel plate door is foamed, uneven quality defects will appear on the surface to varying degrees, which will affect the product appearance and quality reputation. In order to solve this problem, some enterprises thicken the plate to improve the ability of the plate to resist shrinkage and deformation. Some enterprises paste cushioning and isolation materials inside the door shell to weaken the adverse effects caused by the shrinkage o...
