Second step coating cementing agent
At the back side of described hyaline membrane coating cementing agent, the thickness of adhesive layer is the 0.01-0.05 millimeter;
The 3rd step posted hyaline membrane
Described hyaline membrane posted at needs improve on the reflecting surface of projection screen of performance;
The 4th step delineation hair check
With row's cutter that thin blade is formed, on described hyaline membrane surface, depict a large amount of vertically hair checks, the hair check spacing is the 0.5-1.5 millimeter, hair check degree of depth 0.06-0.18 millimeter;
The 5th step was infiltrated dark dye
In described hair check, infiltrate dark dye.
Technical scheme of the present invention is further characterized in that the macromolecule hyaline membrane is the tygon transparent membrane.
Technical scheme of the present invention is further characterized in that, in the first step, the microspike of formation is lengthwise bar ripple, grow crosswise bar ripple or bar ripple in length and breadth, waviness width 0.3-1.5 millimeter, ripple stripe pitch 0.5-1.5 millimeter.
Technical scheme of the present invention is further characterized in that cementing agent is the acrylate adhesive sticker.
Technical scheme of the present invention is further characterized in that the order of specific operation process can be: the first step; The 4th step; Second step; The 3rd step and the 5th step.
Technical scheme of the present invention is further characterized in that the order of specific operation process can be: the first step; The 4th step; The 5th step; Second step and the 3rd step.
Technical scheme of the present invention is further characterized in that the order of specific operation process can be: the first step; Second step and the 3rd step.
Technical scheme of the present invention is further characterized in that in the first step, the height of microspike is 0 millimeter, promptly skips the first step, and the order of all the other operating process is: second step; The 3rd step; The 4th step and the 5th step.
Advantage of the present invention:
1. method of the present invention is simple, and equipment requirements is low, and raw material is inexpensive, and is easy to implement.
2. the processing effect of method of the present invention is good.The hyaline membrane of method processing of the present invention is posted on the reflecting surface of any existing hard and soft projection screen, just can increase watching the angle and improving the contrast that this projection screen is shown picture of this projection screen.
3. method flexible operation of the present invention can change the order of operating process according to the performance deficiency of projection screen reality, and orientation is improved the performance of projection screen.
Description of drawings
Fig. 1 is the sectional view of the projection screen processed of the present invention, and 1 is the reflecting surface of projection screen among the figure, the 2nd, and hair check, the 3rd, hyaline membrane, the 4th, dark dye, the 5th, adhesive layer.
Embodiment
The projection screen that needs the raising performance is the soft curtain of metal.The tygon transparent membrane that with thickness is the 0.10-0.20 millimeter is a raw material, molded by mold hot, form the lengthwise bar ripple of projection, grow crosswise bar ripple or bar ripple in length and breadth at film surface, waviness width is the 0.5-1.5 millimeter, the ripple stripe pitch is the 0.5-1.5 millimeter, makes hyaline membrane;
