Embodiment 1
[0019] Cut the aluminum plate with a thickness of 0.3mm into rectangular blanks according to the requirements of the picture, apply white polishing paste on the blank, use kerosene as the medium to polish it manually with a cloth ball, wipe it with cotton yarn, and wipe it with soft paper poured with kerosene Let the blank board shine, and the picture requires no processing. Paste scotch tape paper on the radial lines, center on the intersection of the two diagonal lines of the blank board, use a bamboo board with a width of 8mm, paste No. 400 water sandpaper, and use a ruler Guide, broach the reflective stripes from the four sides of the base plate to the center, use a 10mm wide bamboo board to paste No. The hard scouring pad is rubbed repeatedly along the above-mentioned broaching direction to make the light even, tear off the scotch tape paper attached to the base plate, remove the dirt, and brush the nitro varnish twice with a wool brush by hand. Proportioning is nitro var...
Embodiment 2
[0021] The brass plate with a thickness of 0.5 mm is cut into circular blanks according to the requirements of the picture, and processed according to the process of embodiment 1. Just select the center point as the center of the blank, and use a cloth wheel for mechanical polishing when polishing. When making reflective radial stripes, use No. 250 water sandpaper to stick it on a 9mm wide bamboo board, and pull the reflective stripes from the circumference to the center. Use No. 600 water sandpaper to paste on a bamboo board with a width of 12mm. During surface treatment, use a spray gun to spray the surface with secondary nitro varnish. The compressed air pressure can be at 0.3-0.5 MPa, and its weight ratio is nitro varnish: Thinner = 1:2.5, after purchasing in the chemical raw material store, mix according to this ratio when using.
Embodiment 3
[0023] The aluminum plate with a thickness of 0.6 mm is cut into an oval shape according to the requirements of the screen design, and processed according to the process method in Example 1. Only the center point is selected as the geometric center of the slab, mechanically polished with a cloth wheel, pasted on a 10mm wide bamboo board with No. 80 water sandpaper, and the reflective radial stripes are broached from the surroundings to the center point, and No. 400 is used for deglazing treatment Water sandpaper is pasted on the bamboo board of 15mm and carries out, with spray gun to surface spraying nitro varnish secondary during surface treatment, compressed air pressure is 0.4 MPa during spraying, and weight proportion is commercially available nitro varnish: diluent=1: 2.5.
