Problems solved by technology
[0003] Most of the back shells of traditional plasma display devices are made of 1.2mm aluminum alloy plate material, mainly because aluminum material has a series of advantages such as high conductivity, easy processing, anti-rust, light weight, etc., but the price of aluminum plate is high, and the yield strength is poor, High thermal conductivity, poor heat insulation performance, and large energy loss. In today's increasingly fierce competition in the home appliance industry, under the condition that the electrical and mechanical properties and anti-rust performance can all be satisfied, it is reasonable to introduce low-cost and better-performing materials. It is particularly important to manufacture the back shell of the plasma display device

Embodiment Construction
[0020] The technical scheme of the present invention is described in detail below in conjunction with specific embodiment:
[0021] The improved electric galvanized panel includes a base material and a galvanized layer attached to the surface of the base material. The yield ratio of the base material is 0.65 to 0.7, especially the closer the yield ratio of the base material is to 0.7, the better. It will not be broken or broken during the stamping process.
[0022] The yield strength ratio of the base material is the ratio of the yield strength of the base material to the tensile strength. When the steel or sample is stretched, when the stress exceeds the elastic limit, the stress does not increase or begins to decrease, while the steel or sample The obvious plastic deformation still continues to occur, which is called yielding, and the minimum stress value when the yielding phenomenon occurs is the yield point; the material reaches the maximum stress value from the beginning ...

Abstract
The invention discloses an improved electric zinc plate and a rear shell of a plasma display device which uses the electric zinc plate, and relates to an electric zinc plate material and the rear shell of the plasma display device. The improved electric zinc plate is designed in order to solve the problems that the rear shell of the prior plasma display device adopts an aluminum plate as the material, and the cost is high. The rear shell of the plasma display device adopts the improved electric zinc plate which comprises a base material and a galvanizing layer which is attached to the surface of the base material; the galvanizing quantity of the galvanizing layer which is arranged on the surface of the electric zinc plate is 55 g / m<2>, the thickness of the electric zinc plate is from 0.45 to 0.6 mm, and the optimal thickness of the electric zinc plate is 0.47 mm. The improved plate of the invention is suitable for being arranged in rear shells of various plasma display devices.
Description
technical field [0001] The invention relates to an electric zinc plate material used for manufacturing the back shell of a plasma display device, and the back shell of the plasma display device. Background technique [0002] Plasma Display Panel (PDP) is a future wall-mounted digital image display device. Compared with traditional image display devices, its main feature is that the thickness is greatly reduced, and even the thickness of large displays above 40 inches can be made The height is less than 10cm, which not only fully saves space, but also has superior brightness and is more elegant in appearance; among them, the design of the rear shell of a plasma display device (such as a plasma TV) plays a decisive role. [0003] Most of the back shells of traditional plasma display devices are made of 1.2mm aluminum alloy plate material, mainly because aluminum material has a series of advantages such as high conductivity, easy processing, anti-rust, light weight, etc., but t...
