2results about How to "Reduce reflective effect" patented technology

The application discloses a kind of low reflection high adhesive photo surface treatment method, successively contain photo surface plasma treatment, UV film solution coating solidification, film outer surface plasma treatment etc., core is in UV film solution adding silane coupling agent type passivator;Photo surface uses atmospheric pressure plasma treatment, film outer surface uses low temperature plasma treatment, by controlling plasma treatment power, speed, working gas etc., realize the micro-nano rough structure construction of photo and film outer surface.The application utilizes double plasma treatment to realize physical roughening and reduce reflection, realizes the stability and chemical coupling of plasma activated surface by passivator, greatly improves the bonding strength of photo and film layer, and finally prepared film encapsulation photo film layer transmittance is greater than or equal to 90%, 60 degree glossiness is 10~30GU, while realizing low reflection effect without losing transparency, also has excellent wear resistance, bending performance.

The utility model discloses a centering beacon which comprises a centering rod, an elastic sleeve, a reflective coating and a plurality of shading fins, according to the application, the reflective coating is arranged on the elastic sleeve, the elastic sleeve can slide up and down on the centering rod and is fixed, the centering bolt is mounted on the forced centering disc during use, and the height difference between the reflective coating and the forced centering disc is obtained through measurement; the centering beacon which can only be used for orientation originally is changed into the centering beacon which can be used for accurately measuring the target height, so that the free station setting function of the total station is realized (space resection), and the cost is not increased; through the cooperation of the plurality of shading fins and the elastic sleeve, the influence of an arc curved surface at the reflective coating on light signal reflection is reduced, a more accurate and stable prism constant (distance correction number) can be obtained, the shading fins are used for shielding the range of large curvature change of the side edge of the cylinder, and the influence of the curvature on the distance correction number is reduced.
