Requirements For Sandpaper Base Paper

Everyone needs to understand the requirements for sandpaper base paper by looking at the appearance quality. Usually, when looking at the original paper, one color should be basically consistent, especially for each batch of natural color paper, otherwise it will affect the color matching of the trademark surface. The amount of dust should not be excessive, and there should be no folds, wrinkles, curtains, or holes, especially on paper of various colors, which should not have spots. Three smoothness requirements: the paper surface should be flat, and the wool marks should not be too obvious. The quantity and thickness on both sides should be consistent, otherwise it is easy to deviate during production. The edges of the four major rolls should be cut neatly at both ends without any breaks. The five paper core tubes are intact and have good hardness. The weight of each large roll should not be too large. Generally, it is recommended to use 300-600kg per roll of paper according to the specifications.
