蜂窩紙板的柔軟度是紙張普遍存在的問題,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 of paper, 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。隨著市場競爭的加劇,制造商們紛紛降價以搶占市場。一些工廠使用劣質(zhì)原材料來降低生產(chǎn)成本。這些低克原紙的特點(diǎn)是厚度不均勻,施膠量小,含沙量高,延性纖維少。這種材料不僅不會被制成硬紙板,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 competition intensifies, manufacturers cut prices to seize the market. Some factories use inferior raw materials to reduce production costs. These low gram base papers are characterized by uneven thickness, small size, high sand content and less ductile fiber. 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,這是錯誤的。相反,紙漿太厚或單面和雙面的機(jī)器太大,這是紙板柔軟的原因。
Many people think that starch paste is too thick or too sticky, which is wrong. On the contrary, the pulp is too thick or the machines of one side and two sides are too large, which is the reason why the cardboard is soft.
3.蜂窩紙板的生產(chǎn)溫度包括蒸汽溫度和環(huán)境溫度。蜂窩紙線蒸湯的溫度通常在165°C到185°C之間。當(dāng)速度高時,應(yīng)提高溫度,降低速度,以避免高溫和低速生產(chǎn)。紙板與環(huán)境之間的溫差太大,使得蜂窩紙板容易吸潮、軟化,尤其是原紙沒有膠水。
3. The production temperature of honeycomb paperboard includes steam temperature and ambient temperature. The temperature of honeycomb paper line steaming soup is usually between 165 ° C and 185 ° C. When the speed is high, the temperature should be increased and the speed reduced 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 has no glue.
4. 壓力調(diào)節(jié)不當(dāng)也會導(dǎo)致紙板變軟。注意雙面壓膠輥與壓膠輥之間的間隙調(diào)節(jié)和熱床壓膠輥的高度控制。當(dāng)壓力輥調(diào)節(jié)過低時,會導(dǎo)致坩堝頂部變形,使紙板承受太大的壓力,造成紙板柔軟。
4. Improper pressure regulation will also cause the cardboard to become soft. Pay attention to the gap adjustment between the double-sided press cot and the press cot and the height control of the hot bed press cot. 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.
