High-light-transmittance organic glass sample preparation equipment and method thereof

Abstract

The invention provides high-light-transmittance organic glass sample preparation equipment and a method thereof, and relates to the technical field of organic glass, the high-light-transmittance organic glass sample preparation equipment comprises a box body, a workbench fixedly mounted in the box body, a forming block fixedly mounted at the top of the workbench, and an extrusion assembly arranged in the forming block and used for compressing a material solution, and the cooling assembly is arranged in the forming block and the workbench and is used for cooling the material. According to the equipment, a top plate, a heat conducting piece, a heat dissipation cavity, a ventilation pipeline and an exhaust fan are matched for use, raw materials can be continuously cooled, the forming speed of organic glass is increased, through matched use of a positioning rod, a positioning hole, a pressing plate, a piston and a connecting rod, the raw materials in a forming groove can be extruded while positioning is conducted, and the forming efficiency is improved. And the situation that gaps are reserved between the raw materials and the forming grooves, the surfaces of the formed organic glass are uneven, and the light transmittance of the organic glass is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of plexiglass, in particular to a device for preparing samples of plexiglass with high light transmittance and a method thereof. Background technique [0002] The chemical name of plexiglass is polymethyl methacrylate, which is a polymer compound polymerized from methyl methacrylate. It is an important thermoplastic that was developed earlier. The plexiglass is divided into colorless and transparent, colored and transparent, pearlescent , Four kinds of embossed plexiglass. Plexiglass has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance. It can be divided into tube profiles, rod profiles and plate materials according to production needs. [0003] In the production process of plexiglass, it is generally divided into steps such as batching, mixing, heating and melting, stirring, and forming. The selecte...

Problems solved by technology

[0004] However, the existing forming molds usually adopt natural cooling to cool the plexiglass raw materials. However, because the temperature of the raw materials after stirring is too high, the waiting time for the plexiglass in the process of cooling and forming is too long. Cooling water is used to cool down, but due to the complex structure of water cooling and large water consumption, it is not conducive to saving water resources, and the temperature of cooling water rises quickly, and the subsequent cooling effect is poor, which is not conducive to the rapid prototyping of plexiglass. During cooling and molding, because the organic glass raw material shrinks in the process of cooling and forming, a gap is formed between the raw material and the forming groove, resulting in uneven surface of the organic glass after molding, which affects the light transmittance of the organic glass, and needs to be refurbished. Grinding and polishing to increase the production process
