Description

Technical Field

[0001] The utility model relates to the field of HDPE locks, in particular to a HDPE lock buckle protection device in HDPE vertical curtain anti-seepage construction. Background Art

[0002] High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its hardness, tensile strength and creep are better than those of low-density polyethylene; it has good wear resistance, electrical insulation, toughness and cold resistance; it has good chemical stability, is insoluble in any organic solvent at room temperature, and is resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air, and low water absorption; it has poor aging resistance, and its resistance to environmental stress cracking is not as good as that of low-density polyethylene, especially thermal oxidation will reduce its performance, so antioxidants and ultraviolet absorbers must be added to the resin to improve this aspect. The heat deformation temperature of high-density polyethylene film is low under stress, so be careful when using it. HDPE is a thermoplastic polyolefin generated by ethylene copolymerization. Although HDPE was launched in 1956, this plastic has not yet reached a mature level. This general material is still developing new uses and markets. The domestic producers of high-density polyethylene (HDPE here does not include HDPE produced by full-density polyethylene units) are CNPC, Sinopec, and CNOOC. As of the end of 2006, there were four HDPE units belonging to CNPC, namely Lanzhou Petrochemical HDPE Unit, Daqing Petrochemical HDPE Unit, Liaoyang Petrochemical HDPE Unit, and Jilin Petrochemical HDPE Unit. HDPE is usually manufactured using the Ziegler-Natta polymerization method, which is characterized by the absence of branched chains on the molecular chain, so the molecular chain is arranged regularly and has a high density. This process uses ethylene as the raw material in a tubular or kettle low-pressure reactor, and uses oxygen or organic peroxide as an initiator to initiate the polymerization reaction.

[0003] In the prior art, for example, the Chinese patent number is CN207700399U, "A HDPE film E-type lock reinforcement", which includes a strip-shaped galvanized flat iron, which is directly extruded and fixed on one side of the bottom of the E-type lock through a hot melt process, and a number of mounting holes are evenly arranged on the galvanized flat iron, which is fixed on the concrete wall or column surface by passing steel nails through the mounting holes. The utility model has a simple structure and low cost, and ensures a reliable connection between the HDPE film and the wall or column.
