如何來控制蜂窩板的含水率?

蜂窩紙板包裝箱應防水防潮。它的作用實際上是保持盒子耐壓。紙張受水的侵蝕,瓦楞紙會坍塌和軟化,大大降低了包裝的安全性。然而,大多數人認識到防水紙箱只是紙箱成型后的防水問題,而忽略了原來紙箱的含水量,其實控制瓦楞紙的含水量對提高瓦楞紙箱的安全性能也非常重要。如何控制蜂窩板的含水率?
Honeycomb cardboard boxes shall be waterproof and moisture-proof. Its function is actually to keep the box pressurized. Paper by water erosion, corrugated paper will collapse and soften, greatly reducing the safety of packaging. However, most people realize that the waterproof carton is only the waterproof problem after the forming of the carton, but ignore the water content of the original carton. In fact, controlling the water content of the corrugated paper is also very important to improve the safety performance of the corrugated box. How to control the moisture content of honeycomb panel?
首先,當瓦楞紙板進入單面機的含水率控制在9% ~ 12%之間時,瓦楞紙板成形效果較好。當瓦楞紙的含水率高于指標時,可以通過增加瓦楞紙的預熱面積或降低瓦楞紙的速度來解決。當瓦楞紙的含水率低于指標時,可以通過噴霧解決。作者認為,當單面蜂窩紙板在向前內插類型和疊加距離的傳送帶的過街天橋是相同的,原始的紙的含水量和瓦楞原紙可以調整更好的含水量是更合適的。立交橋上堆放的單面蜂窩紙板數量不宜過多,但為保證雙面機不停機,單面機換紙時可適當增加單面蜂窩紙板堆放在立交橋上的數量。
First of all, when the moisture content of corrugated board entering the single side machine is controlled between 9% and 12%, the corrugated board forming effect is better. When the moisture content of corrugated paper is higher than the target, it can be solved by increasing the preheating area of corrugated paper or reducing the speed of corrugated paper. When the moisture content of corrugated paper is lower than the index, it can be solved by spray. The author thinks that when the type of single-sided honeycomb paperboard inserted forward is the same as the overpass of the conveyor belt with overlapping distance, the water content of the original paper and the corrugated paper can adjust the better water content is more appropriate. The quantity of single-sided honeycomb paperboard stacked on the overpass should not be too much, but in order to ensure that the double-sided machine does not stop, the quantity of single-sided honeycomb paperboard stacked on the overpass can be appropriately increased when the single-sided machine changes paper.
其次,干燥溫度對蜂窩紙板含水率的影響。蜂窩板生產線的加熱段一般由三(或四)組組成。加熱板的數量由加熱板的尺寸和蜂窩板生產線的速度決定,每套配備獨立的控制閥。為保證單面蜂窩板進入烘干機前的含水率基本相同,可在三層預熱器上調節單面蜂窩板的預熱面積。調整方法為:當含水率過高時,預熱面積增大;當含水率過低時,預熱面積減小。

Secondly, the influence of drying temperature on the moisture content of honeycomb paperboard. The heating section of honeycomb panel production line is generally composed of three (or four) groups. The number of heating plates is determined by the size of the heating plates and the speed of the honeycomb production line. Each set is equipped with an independent control valve. In order to ensure that the moisture content of single-sided honeycomb plate is basically the same before entering the dryer, the preheating area of single-sided honeycomb plate can be adjusted on the three-layer preheater. The adjustment method is: when the moisture content is too high, the preheating area increases; when the moisture content is too low, the preheating area decreases.
由于蜂窩紙板包裝箱的生產過程需要大量的熱量,部分飽和蒸汽在預熱器和瓦楞輥中會變成冷凝水,通常通過疏水閥排出。為了保證凝結水的正常排放,建議每4小時打開疏水閥前的旁路閥3-5分鐘,以保證溫度的相對穩定。
Because the production process of honeycomb cardboard box needs a lot of heat, part of saturated steam will become condensed water in preheater and corrugating roller, which is usually discharged through drain valve. In order to ensure the normal discharge of condensate, it is recommended to open the bypass valve in front of the drain valve every 4 hours for 3-5 minutes to ensure the relative stability of temperature.
建議通過控制糊化量,用玉米淀粉膠制備蜂窩板。它的主要成分是玉米淀粉、水、氫氧化鈉和硼砂。由于蜂窩紙板生產線的不同配置,其速度不同,制備的膠粘劑粘度、濃度和糊化溫度也不同。我希望以上能對你有所幫助。
It is suggested to control gelatinization and prepare honeycomb with corn starch glue. Its main components are corn starch, water, sodium hydroxide and borax. Due to the different configuration of honeycomb paperboard production line, its speed is different, and the viscosity, concentration and gelatinization temperature of the adhesive are also different. I hope the above can help you.
