The efficiency of the multi-functional, high-yield plastic extrusion die mainly leads to high efficiency, low energy consumption and low molding cost. In terms of function, screw extrusion dies are not only used in extrusion molding and mixing processing of polymeric materials, but have also been extended to food, animal feed, electrodes, explosives, building materials, packaging, paste, ceramics and other fields. In addition, the “one-step extrusion process” that combines the granulation and extrusion processes into one is also worthy of attention.
As LED lighting is gradually accepted by the market, the problem of lampshade materials has been plaguing lampshade manufacturers. As a prerequisite, it must have high light transmittance, and at the same time have a considerable light scattering rate and good light source hiding. In the beginning, glass was used as a lampshade, but the glass was not brittle, the light scattering effect was not very good, and it was difficult to meet the lighting requirements. Later, it gradually developed to use resin instead of glass. However, if only the transparent resin is used as the lampshade, although the light transmittance is very high, which can reach substantially more than 90%, the light scattering effect is not ideal, and the light source is poorly covered. The transmittance of white resin is low, which seriously affects the illumination of LED lamps.
The material of the ceiling lamp shade acrylic diffuser is made by scientifically adding light diffusing agents to PMMA particles with optical quality during the production process. Its basic technology is to use scientific production technology to evenly distribute the diffusing agent in the panel. When light passes through the panel, it encounters scattering particles and has optical effects such as refraction, reflection and scattering, so the light can pass efficiently, uniformly and softly. Pass through the planks without exposing the light source.
