Classification Of Laminated Tube

Jun 07, 2017

    The performance of the laminates depends on the substrate and the binder and the molding process.Laminated Tube

    According to its composition, characteristics and heat resistance, laminated pipe can be divided into the following two.

(1) organic substrate laminated tube - to wood pulp insulation paper, cotton fiber paper, cotton, etc. as a reinforcing material. Long-term use of up to 120 ℃ temperature, but also the development of synthetic fiber products for the enhanced material.Laminated Tube

(2) inorganic substrate laminating tube - inorganic glass fiber cloth, alkali-free glass fiber mats, etc. as a reinforcing material. Long-term use of the temperature of 130 ~ 180 ℃, even up to higher temperatures, with the adhesive resin varies.

Laminated plastic products are divided into laminates, laminates, laminated rods and molded laminates in shape and use. Printed circuit with copper clad laminate and capacitive sleeve for high voltage electrical appliances such as adhesive tape die tube, is two special types of laminated plastic products.

    Laminate: Includes laminated cardboard, cloth, glass cloth and copper clad laminate. ① laminated cardboard: from the insulating paper impregnated with synthetic resin made by hot pressing. Has good dielectric properties, mechanical properties and mechanical processing performance, suitable for electrical equipment in a variety of insulating structural parts. ② laminated cloth: cotton cloth impregnated with synthetic resin made by hot pressing. Has good mechanical processing performance, its hardness, anti-split and impact strength than cardboard, but the electrical performance as laminated cardboard, the same use and laminated cardboard. ③ laminated glass cloth board: from the alkali-free glass cloth impregnated with different synthetic resin made by hot pressing. Its mechanical properties, heat resistance, water resistance than laminated cardboard, cloth plate high, but slightly less bonding strength. Use is the same as laminates. ④ copper-clad laminate: alkali-free glass cloth or cotton fiber paper impregnated with phenolic resin or epoxy phenolic resin as the substrate, and one or both sides of the substrate deposited with electrolytic copper foil, and then made by hot pressing. It has good mechanical properties and dielectric properties as well as high peel strength. Mainly used as electronic equipment, printed circuit boards.Laminated Tube

   Rolling tube: including paper, cloth roll products and capacitive tape sets of die. ① paper, cloth roll products: from the insulation winding paper, cotton cloth, glass cloth dip or coated with synthetic resin, the rolling, impregnation and drying made. Commonly used resin for the phenolic resin, epoxy phenolic resin, modified silicone resin. Paper, cloth roll products can be made rod-shaped, tubular or cylindrical. Its dielectric properties and mechanical strength than the general plastic products, but lower than the laminate, cloth plate. Mainly used as insulation structural parts. ② capacitive tape paper tube core: by the coiled paper coated resin, the dry, hot and heat treatment made. Rolling, at a certain thickness, sandwich a layer of aluminum foil as electrodes. It is a series of capacitors with adhesive tape. Can be used for high-voltage transformers and switches for the end of the insulation core. ③ molded laminated tube: from insulating paper, cotton cloth, glass cloth soaked with synthetic resin, made by forming hot pressing. It has rod-shaped molded products, V-rings and other special shapes of molded products. With high mechanical properties, dielectric properties and moisture resistance. Mainly used for electrical, electrical and other equipment, insulation structure components.Laminated Tube
