It is understood that most of the polystyrene plastic particles are used at one time. After millions of tons of white garbage are discarded, they are placed in the natural world. They can neither be rotted and transformed, nor can they be explained by themselves, thus forming a serious environmental pollution on the one hand. On the other hand, it is also a waste of valuable non-renewable resources. How to effectively recycle used polystyrene foam has attracted the attention of researchers in various countries. At present, the recycling and recycling of waste polystyrene foam is carried out by crushing, melting and re-granulating into another material particle, and then adding a corresponding non-adjuvant to be processed into another material. For the above-mentioned recycling and recycling method, the common practice is to crush, melt, pull, cut, etc. the plastic foam through the crusher, but in the method of producing the plastic pellet, there is an incomplete pulverization of the raw material, and the temperature control of the melting It is uneven, and impurities that are mixed in the raw materials cannot be avoided, which results in extremely low production efficiency and damage to the equipment due to the presence of impurities.
A method for preparing a polystyrene foam regeneration resource relates to the field of processing and preparation of recycled granules, by selecting raw materials, air drying, pulverizing, primary impurity removal, melting, extrusion molding, secondary impurity removal, cooling, cutting, quality inspection, packaging Storage.
Select the recycled plastic foam → sort the foam that meets the standard and carry out the natural air drying → the air-dried foam is placed in the pulverizer and pulverized → the pulverized foam is transported to the material hopper in the bubble granulator → set the foam granulator material bucket Feed rate→Preliminary removal of impurities from the pulverized material→Material entering the foam granulator to start melting→The molten material is extruded through the foam granulator extrusion die for the first time→Substance is extruded through the melting die After the impurities are removed, the line-shaped plastic is formed → the line type plastic is cooled and cooled; the line-shaped plastic after cooling is cut into plastic particles → the finished plastic particles are subjected to finished product inspection → the finished product is packaged and stored.
Polystyrene plastic particles are one of the most widely used plastics in the world. Due to their good water resistance, thermal insulation, insulation, low moisture absorption and strong seismic strength, they are light, strong and easy to form. Low price and other characteristics, widely used in packaging, moisturizing, waterproof, heat insulation, shock absorption, decoration, catering and other fields, into the various sectors of the national economy.
This is an Electric Infrared Panel Heater. It heats objects by transferring energy directly from the Electric Heater into the object.Therefore, consider placing the Infrared Panel Heater where it will not be immediately obstructed by objects like furniture or where it cannot effectively radiate out, such as at the edge or in the corners of a room. Objects placed in front of the electric heater will heat up and can prevent effective heat dispersion into the room. Avoid placing it opposite windows or open doorways.
