FRP tower
FRP tower (desulfurization tower, absorption tower, purification tower, washing tower, drying tower, etc.) because of its high temperature resistance, corrosion resistance, wear resistance, long service life and other advantages, mainly used in power plant flue gas desulfurization and denitrification treatment system, metallurgy, petrochemical, electronics, medicine, textile and other environmental protection fields, protect the environment, save energy and create value.
The glass fiber reinforced plastic tower adopts a microcomputer-controlled horizontal fiber winding process, I .e. under the control of the microcomputer, the mold rotates around the axis, and the winding head carries the glass fiber impregnated with resin to reciprocate along the direction of the mold axis. The speed ratio of the two movements is controlled by the microcomputer. The number of winding layers is controlled by the microcomputer according to the parameters input in advance. After the resin is cured, products are formed on the surface of the mold.
1. horizontal winding forming technology features:In the molding process, the mold is parallel to the ground, so it is called horizontal winding. The maximum diameter can reach 15 meters and the length is 20 meters. There are four advantages:
1. Overall molding: the cylinder is wound as a whole (including head), without structural layer joints, the axial force and circumferential force of the cylinder are reasonably and evenly distributed, the overall performance is good, the strength is high, there is no stress concentration area, and the service life is long;
2. Uniform resin content: During the winding process, the equipment is placed horizontally and rotated continuously, and there will be no resin dripping and no uneven resin content;
3, reasonable structure: the use of steel mold, lining injection molding, high resin content, smooth inner surface, no capillary phenomenon. The structural layer is formed by spiral cross winding, and the resin content is 35±5%. The outer protective layer is smooth and uniform in color;
4. Strong bearing capacity of the head: the cylinder and the head are strengthened as a whole to form a bud-type package, and the head has a large capacity to resist wind load, snow load and operating load.
2. implementation standards:HG/T20696-1999 Design Regulations for FRP Chemical Equipment
Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Forging can eliminate the defects such as loose casting in the smelting process and optimize the microstructure. At the same time, due to the preservation of the complete metal flow line, the mechanical properties of forgings are generally better than castings of the same material. Related machinery in high load, severe working conditions of important parts, in addition to the shape of a relatively simple available rolling plate, profile or welding parts, the use of forgings.
