Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a precise mixing equipment for oxidized polyethylene wax and synergistic foaming agent. Background Technology

[0002] Oxidized polyethylene wax is an excellent new type of polar wax. Because the molecular chain of oxidized polyethylene wax contains a certain amount of carbonyl and hydroxyl groups, its compatibility with fillers, pigments, and polar resins is significantly improved. Its wettability and dispersibility in polar systems are superior to polyethylene wax, and it also possesses coupling properties. Foaming agents are substances that create pores in a target material; they can be divided into three main categories: chemical foaming agents, physical foaming agents, and surfactants. In chemical production, the mixing quality of oxidized polyethylene wax and synergistic foaming agents has a crucial impact on the performance of the final product. However, current equipment for mixing oxidized polyethylene wax and synergistic foaming agents often uses manual weighing or simple metering methods, which are easily affected by human factors and equipment precision, leading to deviations in the ratio of oxidized polyethylene wax and synergistic foaming agents, thus affecting the quality stability and consistency of the product. Therefore, we propose a precise mixing equipment for oxidized polyethylene wax and synergistic foaming agents. Utility Model Content
