蜂窝纸板棉的常见问题包括材料,淀粉糊,温度和环境湿度。
Common problems with honeycomb board cotton include materials, starch paste, temperature and ambient humidity.
1.材料的利弊是主要原因。随着市场竞争变得更加激烈,制造商正在推低以抢占市场。一些工厂使用劣质原材料来降低生产成本。这些低克基纸的特征在于厚度不均匀,施胶量小,沉积物浓度高和韧性低的纤维。这种材料不仅不会生产出高质量的纸板,而且还会加速瓦楞辊的磨损。
1. The advantages and disadvantages of materials are the main reasons. As the market becomes more competitive, manufacturers are pushing down prices to take over the market. Some factories use inferior raw materials to reduce production costs. These low-g base papers are characterized by uneven thickness, small size, high sediment concentration and low toughness of fibers. This material will not only not produce high quality cardboard, but also accelerate the corrugating roll wear.
很多人认为淀粉糊太稠或太粘,这是错误的。相反,纸浆太厚或者单面和双面机器太大,这就是纸板柔软的原因。
Many people think starch paste is too thick or too sticky, which is wrong. On the contrary, the pulp is too thick or the single-sided and double-sided machines are too large, which is why the cardboard is soft.
纸板生产温度包括蒸汽温度和环境温度。板生产线的烹饪线的温度通常在165℃和185℃之间。当速度高时,应该增加温度。当车速低时,降低温度以避免高温和低速生产。如果纸板与环境之间的温差太大,纸板很容易吸收水分而变软,尤其是没有胶水的原纸。
Board production temperature includes steam temperature and ambient temperature. The temperature of the cooking line of the board production line is usually between 165 ℃ and 185 ℃. When the speed is high, the temperature should be increased. When the speed is low, reduce the temperature to avoid high temperature and low speed production. If the temperature difference between the paperboard and the environment is too large, the paperboard is easy to absorb water and become soft, especially the base paper without glue.
4.压力调节不当也会导致纸板变软。注意双面机上胶辊和压辊之间的间隙调整以及热床压辊的高度控制。当压力辊调节得太低时,会导致坩埚顶部变形,导致纸板承受过大的压力并导致柔软。
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 machine and the height control of the pressing roll on the hot bed. When the pressure roller is adjusted too low, the top of the crucible will be deformed, which will cause the cardboard to bear too much pressure and lead to softness.
