Detailed Product Description: | After the thermosetting plastic thermoforming become insoluble and infusible cured product, and are commonly used in phenolic resin as a main component phenolics, 4250 as well as high temperature plastic, a polyimide plastic, shaped plastics. Thermoplastic extrusion after heat curing though, but its physical and chemical properties do not change significantly, still soluble, fusible, can be repeated molding. Currently there are two kinds of film forming method, namely continuous impregnation and casting method. First in dimethyl acetamide solution was prepared at a concentration of 15% to 16%, the polyamic acid solution of 20 to 50 seconds reduced viscosity. Then, in order to perform multi-pass dipping machine impregnation operation, with 0.05mm thick aluminum foil as a continuous carrier. Each immersion time have been baked and dried (180 ℃ under), the solvent was removed, immersion speed of 3.5 ~ 6.5m / min. Then, for 30 to 60 minutes at 350 ℃ cutting plexiglass plate acrylic, the polyamic acid film dehydration cyclization. After cooling glass, polyimide film is peeled off from the aluminum foil polycarbonate plate plexiglass rods, ie finished. If polyamide acid was cast in stainless steel baseband continuous operation, through high-temperature baking and dehydration cyclization, to the preparation of the polyimide film. Acrylic tube plexiglass tube bending | plexiglass | Tianjin Tianjin three by three plastic Limited. Three Plastic Co., Ltd. Tianjin (www.tjzsxszp.com) strong, credible, in Tianjin plastic plate (sheet, section), rods and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Tianjin three and you work into the brilliant, for a better future! |
