Problems solved by technology

[0006] Aiming at the problems of low adhesion and poor effect of the powder layer due to technical defects of the powder coating solution, the present invention provides a new type of glass bulb powder coating solution for metal halide lamps, which can promote the dilution and fusion of the solution by adding adhesion to the material. Chemical substances make powder coating easier and more convenient, the thickness of the powder layer is appropriate, it is firmly bonded to the glass bulb, and the yield rate is improved

Abstract

The invention discloses a novel glass shell powder-coating solution for a metal halide lamp. The novel glass shell powder-coating solution comprises the following raw materials: a fluorescent powder, a silica gel solution, an alkaline hydraulic binder, cellulose ether, a foaming agent, a softening agent, an aging agent, a retardant, a tackifying resin, a filler and the balance water. The novel glass shell powder-coating solution for the metal halide lamp has proper self consistency and high conglutination; the powder-coated powder layer thickness is easy to control; the thickness of a coating layer is proper, a requirement for vaguely seeing internal objects is met, and the coating layer has no bubbles and flow marks; the lamp after a glass shell is coated with powder can allow the stability of the coating layer to be kept in a longer time, the powder-coated powder layer has no whole block falling-off phenomenon, and the finished product rate is high. The color rendering property and the light transmittance of the metal halide lamp are ensured, and the service life is improved.

Description

technical field [0001] The invention relates to a high-efficiency adhesive powder coating solution, in particular to a novel glass bulb powder coating solution for metal halide lamps. Background technique [0002] The metal halide lamp is a discharge lamp that works on an AC power source and produces arc discharge in the mixed vapor of mercury and rare metal halides. The metal halide lamp is the first high-pressure mercury lamp made by adding various metal halides. Three generations of light sources. Metal halide lamps have the characteristics of high luminous efficiency, good color rendering performance, and long life. Indoor lighting in other places. [0003] The preparatory work that needs to be done before manufacturing metal halide lamps is: 1. The tools, utensils and measuring tools required for the preparation work, and the materials required for the work. Check whether the equipment is operating normally, and if it is not operating normally, please repair it in ti...
