Often, minerals such as calcium carbonate, silica, clay, kaolin and carbon are added as fillers to polymers. While most people think these are simply used to add bulk and lower cost, many of these mineral fillers make them easier to mold and shape while ensuring the stability of the compounds. For plastics that require heat-resistance, mineral ...

Based on the DM paradigm, a new possibility of plastic recycling supported by additive manufacturing, called distributed recycling by additive manufacturing …

Generally plastic additives can be organized into the following three categories: Antioxidants. These products protect polymers from oxidation, or damage from heat and oxygen, during manufacture, processing, and use. They also improve the processing of the material, which helps reduce waste and energy consumption. More.

4. Colorant Firstly, the addition of colorant should be based on the specific conditions of plastics in the preparation and moulding process. For example, when forming PVC bellows, because PVC will release HCl in the process of forming, it is not appropriate to select acid-sensitive cadmium red, group green, etc.

Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and …
