Abstract
A preparation method for panel shadow masks of color tubes is to rotate a two-picture master by 90deg. to form a four-picture master mask conventionally then to process it to a working mask for exposure. The steel ribbon is cleaned by HNO3 solution and coated with photoresist to be dried in a drying oven and exposed by an exposing lamp then the hard film is processed by chromic acid on a corrosion line and the steel ribbon is dried in a drying oven and corroded with FeCl3 solution. Two spraying booms are added at its top and bottom edges to spray the edge only for increasing the corrosion tolerance of the edge then to be washed and an angled wash is added before the third wash then to be cut conventionally at last.
Description
Technical field
The present invention relates to a kind of preparation method of color picture tube planar mask.
Background technology
No matter produce which kind of planar mask at present, the length direction of shadow mask slotted eye is all identical with the steel band direction of advance with production aborning, and the rolling direction when promptly making with steel band is identical.Because product is various in style in actual production, size, the specification of product have nothing in common with each other, and product arrangement mode aborning will influence the efficient of production and the utilance of steel band.As producing by normal pattern arrangement mode, the production capacity of existing production equipment has idle, yields poorly the production cost height, and the arrangement of product figure necessarily has an optimum composition method that is complementary with capacity of equipment, but former design has limited giving full play to of capacity of equipment.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of the color picture tube planar mask that can enhance productivity, reduce production costs.
For achieving the above object, the technical solution used in the present invention is: the preparation method of two figure mother matrixs is revolved the plate face of two figure mother matrixs and is turn 90 degrees the mother matrix that one edition four figure is made in combination at first routinely, again with the expose working version of production usefulness of the mastering of one edition four figure; Pressure with 0.15Mpa in the nitric acid liquid of 0.02～0.03mol/L carries out pickling to steel band; The pace of steel band is controlled at 3.0m/min steel band is applied photoresists, the flow of control coating photoresists is 35 liters/hour; Applied make behind the photoresists steel band with the speed of 3.0m/min by drying oven, the temperature in control drying oven A district is that 98 ℃, the temperature in B district are that 98 ℃, the temperature in C district are that 80 ℃, the temperature in D district are 70 ℃; Working version is placed on the dried steel band of gluing, with 10～14mw/cm
2Illumination expose with Exposing Lamp, the distance of Exposing Lamp and plane of exposure is 600～800mm, the exposure machine spacing is 50～550mm, 33～37 seconds pumpdown times; Be that 1.6% chromic acid carries out post bake with the speed of production of 3.10m/mim to steel band and handles with percent concentration on the corrosion production line; To place curing oven through the steel band that post bake is handled, be that 70 ℃ hot blast dewaters with temperature successively, is that 100 ℃～110 ℃ Sector East, temperature is that two drying ovens in Westbound of 95 ℃～103 ℃ are cured with temperature again; Be to increase the corrosion allowance of steel band edge, respectively increase by two spray booms up and down, make four jet rods of increase only be injected in the steel band edge that will corrode, under 50 ℃, corrode with liquor ferri trichloridi in the edge of steel band; On the jet etching/downforce is respectively 0.32,0.35,0.32/0.27,0.30,0.27Mpa; Wash behind the jet etching, before the 3rd washing, increase by one group of oblique washing that pressure is 0.20～0.30Mpa; Get final product according to conventional method cutting at last.
Because the present invention is revolved existing shadow mask figure and is turn 90 degrees, on steel band, rearrange production again, be that horizontal back rearranges combination to figure, change the one edition four figure mode of production into by the one edition two figure mode of production, make every exposure production product number once be increased to four by original two, production efficiency can increase substantially, and output can increase more than 30%, has reduced production cost.
Description of drawings
Accompanying drawing is the structural representation of motherboard of the present invention.
Embodiment
Below in conjunction with accompanying drawing invention is described in further detail.
Referring to accompanying drawing, embodiment 1:1) preparation motherboard, the preparation method of two figure mother matrixs is revolved the plate face of two figure mother matrixs and is turn 90 degrees at first routinely, and the mother matrix of one edition four figure is made in combination, again with the expose working version of production usefulness of the mastering of one edition four figure; 2) surface treatment gluing, the pressure with 0.15Mpa in the nitric acid liquid of 0.02mol/L carries out pickling to steel band; The pace of steel band is controlled at 3.0m/min steel band is applied photoresists, the flow of control coating photoresists is 35 liters/hour; Applied make behind the photoresists steel band with the speed of 3.0m/min by drying oven, the temperature in control drying oven A district is that 98 ℃, the temperature in B district are that 98 ℃, the temperature in C district are that 80 ℃, the temperature in D district are 70 ℃; Working version is placed on the dried steel band of gluing, with 10mw/cm
2Illumination expose with Exposing Lamp, the distance of Exposing Lamp and plane of exposure is 800mm, the exposure machine spacing is 75mm, the exposure number be two, 35 seconds pumpdown times; 4) corroding, is that chromic acid production speed with 3.10m/mim on the corrosion production line of 1.6% is carried out the post bake processing to steel band with percent concentration; To place curing oven successively with 70 ℃ hot blast air knife dehydration through the steel band that post bake is handled, carry out dry solidification with the temperature of 100 ℃ and 95 ℃; Be to increase the corrosion allowance of steel band edge, respectively increase by two spray booms up and down, make four jet rods of increase only be injected in the steel band edge that will corrode, under 50 ℃, corrode with liquor ferri trichloridi in the edge of steel band; On the jet etching/downforce is respectively 0.32,0.35,0.32/0.27,0.30,0.27Mpa; Wash behind the jet etching, before the 3rd washing, increase by one group of oblique washing that pressure is 0.20Mpa; Get final product according to conventional method cutting at last.
