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...
