Description

Technical Field

[0001] The utility model relates to the technical field of nylon preparation, in particular to a raw material mixer for preparing low-density micro-foamed reinforced nylon. Background Art

[0002] Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeating amide groups — [NHCO] — on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer. Polyamide is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding a little polyamide fiber to blended fabrics can greatly improve its wear resistance; when stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of folds without breaking.

[0003] At present, nylon products are widely used. They are good materials for replacing steel, iron, copper and other metals with plastics. They are important engineering plastics. Cast nylon widely replaces wear-resistant parts of mechanical equipment and replaces copper and alloys as wear-resistant parts of equipment. They are suitable for making wear-resistant parts, transmission structural parts, household appliance parts, automobile manufacturing parts, screw rods to prevent mechanical parts, chemical machinery parts, and chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screw rods, high-pressure washers, screws, nuts, seals, shuttles, sleeves, sleeve connectors, etc.

[0004] However, most of the current nylon raw material mixing devices are mixed by vertical stirring. Although it can achieve the mixing effect, the material enters from the top, and the material stays in the mixer for a short time during mixing, resulting in poor mixing effect. Reciprocating processing is required, which greatly reduces the mixing efficiency of the material, thereby resulting in poor product quality. Utility Model Content
