Problems solved by technology

[0027] The main disadvantages of this production process are: 1. The extrusion appearance of the product is not stable enough, and the mold needs to be disassembled frequently; 2. The pass rate is low, and it is easy to scrap; 3. The production efficiency is low; 4. The product structure is not tight enough, and white cores appear inside. Stomata, etc.

Embodiment Construction

[0069] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0070] Such as figure 1 Shown, the POM raw material rod production technology of the embodiment of the present invention, it comprises the following steps:

[0071] The first step, ingredients / mixing process:

[0072] Clean up the surrounding environment at the mixing head and blow off the mixer with an air gun to prevent dirt and impurities from entering the mixer and raw materials; pour 100KG raw materials into the mixer, weigh 2-3KG color masterbatch on the raw materials evenly On the surface, start the mixer, and the mixing time is 10-15 minutes, so that the raw materials and the color masterbatch are evenly mixed.

[0073] The second step, feeding process:

[0074] Feed materials in time to ensure that the hopper is not empty, so as to prevent...

Abstract

The invention relates to the technical field of polyformaldehyde, and particularly discloses a POM (polyformaldehyde) raw material rod production process. The POM raw material rod production process comprises the following steps of: a burdening/material mixing process, a material charging process, an extruding process, an exhaust process, a shaping/sizing process, a traction/ brake process, a cutting/stockpiling process, and a heat treatment process. The POM raw material rod production process provided by the invention has the advantages that the extruding product is stable, the continuous production is realized, the qualification rate of a product is greatly improved, and the rejection rate is reduced; and meanwhile, the production efficiency is greatly improved, the energy is saved, the consumption is saved, the manufacturing cost is saved, the product structure is tight, an inner white core and an air hole are greatly improved, and the POM raw material rod production process has application and popularization values.

Description

technical field [0001] The invention relates to the technical field of polyoxymethylene, in particular to a production process for POM raw material rods. Background technique [0002] In the past, the production process of POM raw material rods was: batching / mixing process, feeding process, drying process, extrusion process, forming / setting process, traction process, cutting board / stacking process, heat treatment process. [0003] 1. Ingredients / mixing process: [0004] Clean up the surrounding environment at the mixing head and blow off the mixer with an air gun to prevent dirt and impurities from entering the mixer and raw materials; pour 100KG raw materials into the mixer, weigh 2-3KG color masterbatch on the raw materials evenly On the surface, start the mixer, and the mixing time is 10-15 minutes, so that the raw materials and the color masterbatch are evenly mixed. [0005] 2. Feeding process: [0006] Feed in time to ensure that the hopper is not empty, so as to pr...
