The moisture content is refers to the paper and the cardboard under the stipulation drying temperature, when dries to the constant weight, reduces quality and the test specimen proper mass ratio, by percentage expression. The moisture content determination paper and the cardboard performance's important target, the moisture content to the paper and the cardboard tensile strength, the folding endurance, the burst, the deflection and so on has the very important influence. The moisture content high paper is soft, it will bear pierces the intensity and bears performance and so on broken intensity to drop relatively; The moisture content low paper is dry, the paper becomes sends crisply. The hope obtains the best intensity value moisture content in the corrugated cardboard production is 6%~8% generally. 累的手都不好使了`!
