[0001] The present invention relates to the technical field of polypropylene production, in particular to a synthesis device for polypropylene production. Background Art

[0002] Polypropylene (PP) is a polymer synthesized from propylene by addition polymerization. It has a white waxy appearance and is transparent and lightweight. Its chemical formula is (C3H6) n , density is 0.89~0.91g / cm 3 , with a melting point of 164-170°C and an operating temperature range of -30-140°C. Its production mainly depends on propylene monomer, which is usually extracted and processed from hydrocarbons in natural gas or petroleum.

[0003] Polypropylene has the following characteristics: odorless, tasteless, non-toxic, it is the lightest of the commonly used resins, has excellent mechanical properties, including tensile strength, compressive strength and hardness, as well as outstanding rigidity and bending fatigue resistance, good heat resistance, continuous use temperature can reach 110-120 ° C, good chemical stability, except for strong oxidants, it does not react with most chemicals, excellent electrical properties, good high-frequency electrical insulation, and also has good electrical insulation in humid environments; due to these characteristics, polypropylene is widely used in many fields: for clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts It is used in the production of parts, conveying pipelines, chemical containers, etc., for food and medicine packaging, for injection molding and extrusion molding, to make various products and various fibers, narrow strips and films, etc. It is used in the manufacture of various parts in industrial sectors such as refrigerators, air conditioners, televisions, and machinery, and for the manufacture of cold and hot water pipes and fittings for water supply and drainage.

[0101] During specific use, those skilled in the art place the catalyst between the catalyst placement box 411 and the expansion plate 441, and start the hydraulic cylinder 454 of the expansion drive assembly 45, so that the hydraulic cylinder 454 drives the expansion rod 455 to move, thereby driving the expansion plate 441 to slide and expand along the guide groove 432, so that the expansion plate 441 squeezes the catalyst, and by adding petroleum ether into the interior of the high-pressure reaction box 311 and starting the high-pressure reaction box 311, the high-pressure reaction box 311 is heated to the interior, and then by starting the first telescopic rod 12, the absorber 14 is brought into contact with the discharge valve 323, so that the absorber 14 absorbs the heated air in the high-pressure reaction box 311 and combines it with nitrogen. The injector 24 is used to make the nitrogen injector 24 contact with the injection valve 322, and nitrogen is added to the high-pressure reaction box 311. The nitrogen is continuously absorbed by the absorber 14, thereby ensuring that the high-pressure reaction box 311 is in a vacuum state.
