Method for producing back plate of liquid crystal television

Abstract

The invention relates to the field of color-coated steel sheet production, and particularly to a method for producing a back plate of a liquid crystal television. The method is characterized in that the raw steel material is required to be deep-draw steel at DX53D+Z or above; the surface is required to reach the quality standard of FB level or above; and started with the process control adjustment of pre-treatment, coating and packaging, curing, cooling procedures and coiling technology in the production process, the method for producing the back plate of the liquid crystal television comprises the specific control steps of: 1) carrying out the pre-treatment process, including, pre-degreasing, pre-cleaning, pre-rinsing, and controlling a speed of a production line within 50-70 m / min; 2) passivating, and coating primer and finish paint on the front side of the product and back paint of a product; 3) drying and curing at 18-226 DEC G; 4) cooling strip steel; and 5) using a paper sleeve when coiling the strip steel on line. Compared with the prior art, the method for producing the back plate of the liquid crystal television has the beneficial effects of realizing the quality characteristic requirements of the back plate of the liquid crystal television, and realizing production of a back plate of a liquid crystal television with a good appearance and excellent performances through a color coating technology.

Description

technical field [0001] The invention relates to the field of production of color-coated steel plates, in particular to a production method of a back plate for a liquid crystal television. Background technique [0002] For a long time, most LCD TV backplanes have been made of plastic parts, which have been widely used because of their light weight, easy molding, and suitable for small screens. In recent years, with the breakthrough of liquid crystal display technology, the field of LCD TV products has developed rapidly, and has rapidly expanded to large-size specifications. Changes in size specifications have triggered quality characteristics such as the strength of the TV backplane, heat dissipation, and anti-leakage of electromagnetic waves. need. In order to solve this technical problem and further reduce production costs, some TV companies or their backplane suppliers have begun to seek steel factories to directly produce LCD TV backplanes through the color coating proce...

Problems solved by technology

In order to solve this technical problem and further reduce production costs, some TV companies or their backplane suppliers have begun to seek steel factories to directly produce LCD TV backplanes through the color coating process, while washing machines, refrigerators, freezers, microwave ovens, set-top boxes , solar water heaters, lamps, televisions and a series of outer panels of home appliances, especially the outer panels of televisions have the highest quality requirements, requiring perfect appearance, deep drawing, fingerprint resistance, electrical conductivity and other quality characteristics, process control Very complicated, the production process control is extremely unstable, and it is difficult to meet the quality requirements of high-end customers
