▎ 摘　　要

NOVELTY - Processing corrugated pipe resistant to strong acid and alkali corrosion and high temperature comprises (i) adding polyethylene resin, ethylene glycol, phenolphthalein, catalyst, and antioxidant to a reaction kettle, stirring, heating for esterifying, adding stabilizer to the obtained product, performing polycondensation reaction under vacuum, discharging the material, cooling and cutting to obtain modified master batch, and (ii) mixing modified master batch, nano silicon carbide, processing auxiliary agent, epoxy resin, silicone resin, carbon powder, nickel powder, irradiation crosslinking accelerator, modified anti-aging flame-retardant blend, weathering agent, and plasticizer in a high-speed mixer, placing in a double-screw extruder, melting and extruding to obtain a semi-finished corrugated pipe, and conveying the semi-finished corrugated pipe to the processing device for cutting. USE - The method is useful for processing corrugated pipe resistant to strong acid and alkali corrosion and high temperature. ADVANTAGE - The method: replaces the flexible diethanol part in the polyester macromolecular chain with rigid phenolphthalein groups; forms a fragment of rigid diacid monomer and rigid phenolphthalein monomer; enhances the rigidity and crystalline properties of the entire molecule; can meets the contact and support of the outer surface of corrugated pipes of different diameters; ensures that the bellows can be efficiently and comprehensively cleaned in the guide channel; and avoids the blockage of part of the atomizing nozzles with the corresponding structural design of the driveable bellows and the situation that the surface of the bellows cannot be completely cooled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a corrugated pipe resistant to strong acid and alkali corrosion and high temperature prepared by above mentioned method.
