Problems solved by technology

[0004] If the current plastic granules are stored, if the container is damaged, it is very easy to cause the plastic to be damp, which will increase the moisture content of the plastic, so that air bubbles will form in the plastic products made of plastic granules, which will seriously affect the quality of plastic granules and affect the later plastic products. production, reducing the quality of plastic finished products

Embodiment 1

[0048] see Figure 1-8 , a process for treating recycled plastic particles, comprising the following steps:

[0049] S1, first, use a roller powder coating machine to coat epoxy resin particles on the surface of plastic particles, and the epoxy resin particles are pretreated. The pretreatment method is: use alkaline solution to soak the epoxy resin raw material to reduce the water absorption of the epoxy resin To prevent the epoxy resin from absorbing a large amount of water by reducing the adsorption of the epoxy resin, to prevent the generation of air bubbles on the recycled plastic particles after treatment, and to use the pretreated epoxy resin particles after drying. Epoxy resin particles at 400°C, recycled plastic particles with a ignition point higher than 500°C, and the melting points of both epoxy resin particles and recycled plastic particles are lower than 300°C;

[0050] S2, and then proceed to bake the recycled plastic particles to melt the epoxy resin particles ...

Abstract

The invention discloses a plastic regeneration particle treatment process, and belongs to the technical field of plastic particle treatment. The plastic regeneration particle treatment process comprises the following steps: firstly, coating the surfaces of plastic particles with epoxy resin particles by using a roller powder coating machine; then baking the plastic regeneration particles such that the epoxy resin particles on the surfaces of the plastic regeneration particles are molten and form a resin film; then soaking the baked plastic regeneration particles in industrial ethyl alcohol; then draining the plastic regeneration particles and then laying on a metal net, then carrying out flame treatment on the surfaces of the plastic regeneration particles, igniting for 5-10 seconds, and then extinguishing and introducing low-temperature carbon dioxide to cool the plastic regeneration particles; and finally drying the treated plastic regeneration particles, storing and warehousing, preparing a film on the surfaces of the particles by using resin, and then carrying out flame treatment on the particles. According to the process, a resin and plastic mixed layer is formed on the surfaces of the plastic particles while repairing and filling of pores in the surfaces of the plastic particles are achieved, the water absorption of the plastic particles is reduced, and damping is prevented during storage.

Description

technical field [0001] The invention relates to the technical field of plastic granule treatment, in particular to a plastic regenerated granule treatment process. Background technique [0002] Plastic recycled granules, recycled granules are the abbreviation of recycled plastic granules. Recycled plastic granules belong to the category of plastic granules. Recycled plastics are plastics produced by recycling used new materials or waste plastics through a screw machine. Then it is cut into granulated plastic granules by a granulator. It is processed from discarded plastic products and has a broad market. No matter around the world, wherever there are people, it is inevitable to produce waste plastics, and the price is low. [0003] Plastic granules are an indispensable raw material in the plastic processing process. They play an extremely important role in production and research. In industrial production and life, the use of plastic is ubiquitous and has extremely importa...
