Although there will be various problems in the manufacturing process of plastic pallets, there are pits on the surface of the products manufactured by participating in the black masterbatch. What is the reason? There are several situations here. If the surface of the pitted surface is concave If you enter it, it means that the small molecules in the black masterbatch are formed by volatilization, which proves that the white oil in the black masterbatch is increased. If the pits on the plastic tray are raised, it clarifies the carbon in the black masterbatch. The black particles are not even average, perhaps because the black masterbatch in the plastic tray contains too much calcium carbonate or too much white oil, which is squeezed by machinery and equipment to form some aggregated lumps that cannot be evacuated. At this time, we have to compare the concentration. Low black masterbatch, or more slippery evacuation of the masterbatch can be more powerful machinery and equipment, thus creating a complete plastic pallet.
If our plastic pallets are not used outdoors and are not exposed to the sun's ultraviolet rays, we can use a black masterbatch with a calcium carbonate content of 10%. This kind of masterbatch is cheap, evacuates evenly, the color is not affected, and the surface shines. The product strength requirement is also small. If the calcium carbonate inside is too low, the surface of the plastic tray will be rough, and the strength will drop and the color will not shine. If it exceeds the 10% range, it will also cause the same consequences. If we say The plastic pallets need to be used outdoors, and the black masterbatch with calcium carbonate is unlucky for the product and cannot be selected.
