蜂窩紙板棉的常見問題包括材料，淀粉糊，溫度和環(huán)境濕度。
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。隨著市場競爭變得更加激烈，制造商正在推低以搶占市場。一些工廠使用劣質(zhì)原材料來降低生產(chǎn)成本。這些低克基紙的特征在于厚度不均勻，施膠量小，沉積物濃度高和韌性低的纖維。這種材料不僅不會生產(chǎn)出高質(zhì)量的紙板，而且還會加速瓦楞輥的磨損。
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.
很多人認(rèn)為淀粉糊太稠或太粘，這是錯(cuò)誤的。相反，紙漿太厚或者單面和雙面機(jī)器太大，這就是紙板柔軟的原因。
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.
紙板生產(chǎn)溫度包括蒸汽溫度和環(huán)境溫度。板生產(chǎn)線的烹飪線的溫度通常在165℃和185℃之間。當(dāng)速度高時(shí)，應(yīng)該增加溫度。當(dāng)車速低時(shí)，降低溫度以避免高溫和低速生產(chǎn)。如果紙板與環(huán)境之間的溫差太大，紙板很容易吸收水分而變軟，尤其是沒有膠水的原紙。
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.壓力調(diào)節(jié)不當(dāng)也會導(dǎo)致紙板變軟。注意雙面機(jī)上膠輥和壓輥之間的間隙調(diào)整以及熱床壓輥的高度控制。當(dāng)壓力輥調(diào)節(jié)得太低時(shí)，會導(dǎo)致坩堝頂部變形，導(dǎo)致紙板承受過大的壓力并導(dǎo)致柔軟。
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.
