The softness of honeycomb paperboard is a common problem in papermaking and cotton, mainly including material, starch paste, temperature and environmental humidity.

　　1. 材料的优点和缺点是主要原因。随着市场竞争的加剧，制造商纷纷降价以抢占市场份额。一些工厂使用劣质原材料来降低生产成本。这些低克纸的特点是厚度不均匀、施胶量小、含沙量高、延性纤维少。这种材料不仅不会被制成纸板，还会加速瓦楞辊的磨损。

　　1. The advantages and disadvantages of materials are the main reasons. As the market competition intensifies, manufacturers cut prices to seize market share. Some factories use inferior raw materials to reduce production costs. These low-g papers are characterized by uneven thickness, small size, high sand content and less ductile fibers. This material will not only not be made into cardboard, but also accelerate the corrugating roll wear.

　　许多人认为淀粉糊太厚或太粘，这是错误的。相反，纸浆太厚或单面和双面的机器太大，这就是为什么纸板是软的。

　　Many people think that starch paste is too thick or too sticky, which is wrong. On the contrary, the paper pulp is too thick or the machines of one side and two sides are too large, which is why the paper board is soft.

　　3.蜂窝板生产温度包括蒸汽温度和环境温度。蜂窝纸线蒸汤的温度一般在165℃~ 185℃之间。当转速高时，应提高温度和降低温度，以避免高温和低速生产。纸板与环境温差过大，使得蜂窝纸板易吸潮软化，尤其是原纸无胶。

　　3. Production temperature of honeycomb panel includes steam temperature and ambient temperature. The temperature of honeycomb paper line steaming soup is generally between 165 ℃ and 185 ℃. When the speed is high, the temperature should be increased and decreased to avoid high temperature and low speed production. The temperature difference between the paperboard and the environment is too large, which makes the honeycomb paperboard easy to absorb moisture and soften, especially the base paper without glue.

　　4. 压力调节不当也会导致纸板变软。注意双面印刷机上胶辊与压辊之间的间隙调节和热床压辊的高度控制。当压力辊调节过低时，会导致坩埚顶部变形，使纸板承受过大的压力，导致纸板柔软。

　　4. Improper pressure regulation will also cause the cardboard to become soft. Pay attention to the gap adjustment between the rubber roll and the pressing roll on the double-sided printing machine and the height control of the hot bed pressing roll. When the pressure roller is adjusted too low, it will cause the top of the crucible to deform, which will make the cardboard bear too much pressure and make the cardboard soft.
