Do You Know Diffuser Acrylic Sheet?

Diffuser acrylic sheet is very useful. Diffusion films can be divided into two types according to the principle of optical design and manufacturing process, namely, coating particle type and micro lens array type. The coated particle-type diffusion film has the advantages of high light transmittance, large haze adjustment range, good appearance quality, large scale of production, high yield, and is therefore the main production process of the diffusion film. At present, most of the diffusion membranes used by major panel factories at home and abroad are coated particle types. In recent years, with the advent of new manufacturing methods for diffusion membranes and new combination products, the production of microlens array diffusion films has also been continuously enlarged and manufactured in Korea. The interlayer structure of the diffusion film is mainly composed of a base material, a diffusion film, and a release prevention layer.

The diffusion coating of the coated particle diffusion film is that the particles are uniformly dispersed in the adhesive layer, and the adhesive layer adheres to the surface of the polyester film. The size-blended particles are the main media for light diffusion. The anti-adhesive edge layer is a small bump with a space below the substrate, so that the surface between the diffusion film and the backlight light guide plate becomes point contact, thereby preventing the diffusion film from sticking to the light guide plate to form a watermark and preventing the diffusion film. Scratches and other damage to the light guide plate.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

How much do you know about PMMA Diffuser Sheet?

Background, technical characteristics, principle and application of PMMA diffuser. High Quality PMMA Diffuser Sheet , a material with light diffusing properties, is one of the types of diffuser plates of PS (polystyrene), PC (polycarbonate), PP (polypropylene), etc. The optical characteristics of plastic sheets such as haze, high light transmittance and high diffusivity can effectively convert point or line light sources into soft and uniform surface light sources. Under the premise of achieving good light transmittance, they also have good The light source lattice shielding property is an ideal optical material for solving the secondary light distribution of LED lamp products, and is the best light diffusion material for LED lighting products. PMMA Diffuser Sheet First, the PMMA diffuser produces a background In the process of LED lighting fixtures being gradually accepted by the market, the problem of LED lamp masks has been plagued by lamp manufacturers, which must have h...

Development Background of LED Diffuser Sheet

Led diffuser plate  is an important part from the past to now. Glass was used as the lampshade initially, but the glass was not brittle and the diffusion effect of light was not very good. It was difficult to meet the lighting requirements. Later, it gradually developed to replace glass with resin, but if only transparent resin lampshade, although the light transmittance is high, the basic can reach more than 90%, but the light diffusion effect is not ideal, poor light concealment. The white resin, whose light transmittance is too low, seriously affects the illumination of the LED lamp. In this case, techniques such as adding milky white pigments and surface scrubbing aids are used. Although this solves the issue of light source shielding, there is an excessively low light transmittance, which seriously affects the efficacy of LED lighting. Therefore, the problem of diffusion masks has been plagued by problems. In such a contradictory problem of light rate and light source shieldin...
