Many manufacturers may not pay much attention to such problems during production, nor do they have high requirements for the production process, so many products are very rough, which may make customers excluded from the choice when purchasing, not at all. Considering that in order to better increase sales, it is necessary to understand the reasons for its roughness and make timely changes. Sometimes rough PVC plastic particles are produced in the production process, most likely because its calcium carbonate is not fine enough, which will cause the filter screen to not be able to filter out its impurities well, so it must be ensured during production. Too much calcium acid is fine enough. Another reason is the storage environment of calcium carbonate, perhaps because the storage environment of calcium carbonate causes it to contain too much moisture, resulting in a rough surface.
