Impregnated mesh is a metal mesh treated by the impregnated plastic process, this process usually refers to the metal products such as wire mesh, wire mesh, metal frame, etc. pre-treated by rust removal, oil removal, and then immersed in molten plastic powder, so that the plastic powder melted at high temperatures and evenly wrapped in the metal surface, after cooling to form a layer of tough and corrosion-resistant plastic coating.
PE (polyethylene) impregnated plastic powder is widely used in the production of impregnated plastic grid because of its good mechanical properties, chemical stability and anti-aging properties. The molded grid products are not only beautiful in appearance, diverse in color, but also have excellent wear resistance, weather resistance and corrosion resistance, which are suitable for applications under a variety of environmental conditions, such as supermarket shelves, warehousing logistics, agricultural fences, highways and railway guardrail and other fields.
The article may describe in detail the production process of the impregnated mesh frame, including:
Pre-treatment of metal grid: cleaning, rust removal, phosphating and other steps of metal materials to improve the binding force of plastic coating and substrate.
Formula design of impregnated plastic powder: According to the use environment and performance requirements of the final product, select the appropriate PE resin, and with pigments, fillers, additives, etc., to design the formula of impregnated plastic powder that meets the requirements.
Immersion process control: The pre-treated grid is immersed in a high temperature furnace equipped with PE immersion powder, and factors such as temperature, time and speed are controlled to ensure that the plastic powder can be fully melted and uniformly attached to the metal surface.
Cooling and post-treatment: natural cooling or water cooling after removal from the furnace, so that the plastic coating curing molding, and then dressing, inspection and other subsequent processes.
