蜂窩紙板的柔軟性是造紙和棉花普遍存在的問題，主要包括材料、淀粉糊、溫度和環(huán)境濕度。
The softness of honeycomb paperboard is a common problem in papermaking and cotton, mainly including material, starch paste, temperature and environmental humidity.
1. 材料的優(yōu)點(diǎn)和缺點(diǎn)是主要原因。隨著市場(chǎng)競(jìng)爭(zhēng)的加劇，制造商紛紛降價(jià)以搶占市場(chǎng)份額。一些工廠使用劣質(zhì)原材料來降低生產(chǎn)成本。這些低克紙的特點(diǎn)是厚度不均勻、施膠量小、含沙量高、延性纖維少。這種材料不僅不會(huì)被制成紙板，還會(huì)加速瓦楞輥的磨損。
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.
許多人認(rèn)為淀粉糊太厚或太粘，這是錯(cuò)誤的。相反，紙漿太厚或單面和雙面的機(jī)器太大，這就是為什么紙板是軟的。
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.蜂窩板生產(chǎn)溫度包括蒸汽溫度和環(huán)境溫度。蜂窩紙線蒸湯的溫度一般在165℃~ 185℃之間。當(dāng)轉(zhuǎn)速高時(shí)，應(yīng)提高溫度和降低溫度，以避免高溫和低速生產(chǎn)。紙板與環(huán)境溫差過大，使得蜂窩紙板易吸潮軟化，尤其是原紙無膠。
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. 壓力調(diào)節(jié)不當(dāng)也會(huì)導(dǎo)致紙板變軟。注意雙面印刷機(jī)上膠輥與壓輥之間的間隙調(diào)節(jié)和熱床壓輥的高度控制。當(dāng)壓力輥調(diào)節(jié)過低時(shí)，會(huì)導(dǎo)致坩堝頂部變形，使紙板承受過大的壓力，導(dǎo)致紙板柔軟。
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 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.
