為了保證瓦楞紙板的強度和良好的附著力，瓦楞紙板的成型應根據(jù)瓦楞紙板生產(chǎn)線的不同配置進行調整。
In order to ensure the strength and good adhesion of corrugated board, the forming of corrugated board should be adjusted according to the different configuration of corrugated board production line.
1. 當瓦楞紙進入單面機的含水量控制在9% - 12%之間時，瓦楞紙成型是理想的。當瓦楞紙含水率高于上述指標時，可通過增加預熱面積或降速度來解決。當瓦楞紙的含水量于上述指標時，可采用噴霧溶液。作者認為,單面瓦楞紙板通過快速進料輸送帶是積極的類型和積累在天橋距離是一致的,紙和瓦楞紙水分調整好,含水量是合適的,單面瓦楞紙板在橋梁樁的數(shù)量不宜過多,不間斷,但為了保證雙面機在單面機上的紙張，單面瓦楞紙板在立交橋上的堆積量可以適當增加。
1. When the water content of the corrugated paper entering the single-sided machine is controlled between 9% - 12%, the corrugated paper forming is ideal. When the moisture content of corrugated paper is higher than the above index, it can be solved by increasing the preheating area or reducing the speed. When the moisture content of corrugated paper is lower than the above index, spray solution can be used. The author thinks that the positive type of single-sided corrugated board passing through the fast feeding conveyor belt is consistent with the accumulation in the overpass distance, the water content of paper and corrugated paper is well adjusted, and the water content is appropriate. The number of single-sided corrugated board in the bridge pile should not be too much and uninterrupted, but in order to ensure the paper of double-sided machine on single-sided machine, the accumulation of single-sided corrugated board on the overpass can be increased appropriately.
2. 烘干機的溫度對瓦楞紙板的含水率有很大的影響。瓦楞紙板生產(chǎn)線的加熱段通常由三組(或四組)組成，其數(shù)量由加熱板的大小和瓦楞紙板生產(chǎn)線的速度決定，每組配備一個獨立的控制閥。為了保證單面瓦楞紙板在進入烘干機前的含水率基本相同，可以通過調整三聯(lián)式預熱器上單面瓦楞紙板的預熱面積來解決問題。調整方法如下:當含水率過高時，預熱面積增大;當含水量過時，預熱面積減小。
2. The temperature of the dryer has a great influence on the moisture content of the corrugated board. The heating section of the corrugated board production line is usually composed of three groups (or four groups), the number of which is determined by the size of the heating plate and the speed of the corrugated board production line. Each group is equipped with an independent control valve. In order to ensure that the moisture content of the single-sided corrugated board is basically the same before entering the dryer, the problem can be solved by adjusting the preheating area of the single-sided corrugated board on the triple preheater. The adjustment method is as follows: when the moisture content is too high, the preheating area increases; when the moisture content is too low, the preheating area decreases.
3.由于瓦楞紙板生產(chǎn)過程帶走大量的熱量,飽和蒸汽的一部分進入預熱器中冷凝和瓦楞輥,通常通過疏水裝置,為了保證正常排出冷凝水,作者建議明渠設備每4小時前的旁通管閥3 ~ 5分鐘,以確保溫度相對穩(wěn)定?？刂颇z水的量通常是用來制造瓦楞紙板是玉米淀粉膠粘劑,其主要成分是:玉米淀粉、水、氫氧化鈉和硼砂,由于瓦楞紙板生產(chǎn)線配置,它的速度是不同的,膠的粘度、濃度、糊化溫度也不同。隨著施膠量的大小，瓦楞紙板的含水量也會發(fā)生變化。當上膠量不小時，瓦楞紙板的含水量不小，反之，不小。單面機和雙面機的膠輥與限位輥之間的間隙一般為0.2mm ~ 0.25mm。瓦楞輥與單面機下膠輥之間的間隙一般為0.1mm ~ 0.2mm。雙面壓輥(接觸桿)與膠輥之間的間隙應略小于單面瓦楞紙板的高度0.05mm ~ 0.1mm。上面的間隙可以用塞尺測量，但是兩個滾子應該是平行的。
3. Because the corrugated board production process takes a lot of heat, part of the saturated steam enters the preheater for condensation and corrugating roll, usually through the drainage device, in order to ensure the normal discharge of the condensate, the author suggests that the open channel equipment bypass pipe valve every 4 hours before 3 to 5 minutes to ensure the relative stability of the insulation. The amount of glue is usually used to make corrugated board, which is corn starch adhesive. Its main components are corn starch, water, sodium hydroxide and borax. Because of the configuration of corrugated board production line, its speed is different, and the viscosity, concentration and gelatinization temperature of the glue are also different. With the size of sizing, the water content of corrugated board will also change. When the amount of glue, corrugated board moisture content is not small, on the contrary, not small. The gap between the rubber roll and the limit roll of single-sided machine and double-sided machine is generally 0.2mm ~ 0.25mm. The gap between the corrugating roller and the lower rubber roller of the single-sided machine is generally 0.1mm ~ 0.2mm. The gap between the double-sided pressing roller (contact rod) and the cot shall be slightly less than the height of the single-sided corrugated board by 0.05mm ~ 0.1mm. The above clearance can be measured with feeler gauge, but the two rollers should be parallel.
溫度和相對濕度的變化(夏季和冬季),膠水的量也比較少,原因是粘合劑的粘度在夏天變得更薄,濃度可以調節(jié)適當增加固體含量,使用環(huán)壓指數(shù)高吸濕的瓦楞原紙;提高粘結劑的溫度可以保證冬季粘結劑流動性差。
The change of temperature and relative humidity (summer and winter), the amount of glue is also relatively small, because the viscosity of adhesive becomes thinner in summer, the concentration can be adjusted to appropriately increase the solid content, and the corrugated base paper with high moisture absorption of the ring pressure index is used; improving the temperature of adhesive can guarantee the poor fluidity of adhesive in winter.
