瓦楞板紙平整度是瓦楞紙箱出產(chǎn)技術(shù)中的重要目標之一，它直接關(guān)系到產(chǎn)品印刷、模切或開槽切角的質(zhì)量。瓦楞板紙平整度差，會發(fā)生瓦楞紙板多種拱形狀、機械化吸附式送印時容易卡住及造成紙板作廢而被迫停機收拾。那么究竟是何原因，影響瓦楞紙箱紙板平整度的呢？下面小編就此問題進行分析。

The flatness of corrugated paper is one of the important goals in the production technology of corrugated box, which is directly related to the quality of product printing, die cutting or slotting. Due to the poor flatness of corrugated board, there are many kinds of arch shapes of corrugated board, which are easy to get stuck in the process of mechanical adsorption printing, and the cardboard will be discarded and forced to stop for cleaning. So what is the reason that affects the flatness of corrugated cardboard? The following is an analysis of this issue.

影響瓦楞紙箱紙板平整度的主要原因如下：

The main reasons that affect the flatness of corrugated cardboard are as follows:

1、面里紙品種、等級不同。有進口、國產(chǎn)牛皮紙、仿牛皮紙、瓦楞紙、茶板紙、高強度瓦楞紙等，又分A、B、C、D、E、級。按紙質(zhì)差用料，一般面紙比里紙好些。

1. The varieties and grades of the paper are different. There are imported, domestic kraft paper, imitation kraft paper, corrugated paper, tea board paper, high-strength corrugated paper, etc., also divided into a, B, C, D, e, grade. According to the paper material, general face paper is better than inside paper.

2、面里紙主要技術(shù)參數(shù)不同。從紙箱性能要求或用戶從降低成本考慮，要求紙箱的面里紙有別，通常是：

2. The main technical parameters are different. In order to meet the requirements of carton performance or reduce the cost, the paper inside the carton is required to be different

（1）面里紙定量不同。有面紙比里紙定量大的，也有小的。

(1) The amount of paper in the flour is different. There are face paper larger than inner paper, and there are also small ones.

（2）面紙里紙含水率不同。因供貨方、運送庫存等環(huán)境濕度不同、有面紙比里紙含水率大的，也有小的。

(2) The moisture content of tissue is different. Due to the different humidity of the environment such as the supplier, transportation and inventory, the moisture content of the face paper is larger than that of the lining paper, but also smaller.
           

（3）面里紙定量、含水率都不同。一是面紙定量大于里紙，含水大于里紙或小于里紙。二是面紙定量小于里紙，含水率大于里紙或小于里紙。

(3) The ration and moisture content of the paper are different. First, the ration of face paper is larger than that of inner paper, and the moisture content is larger or smaller than that of inner paper. The other is that the ration of face paper is smaller than that of inner paper, and the moisture content is larger or smaller than that of inner paper.

3、同批紙含水率不同。一部分紙含水率大于另一部分紙或筒紙兩端間、外緣側(cè)與內(nèi)芯側(cè)含水率不同。

3. The moisture content of the same batch of paper is different. The moisture content of one part of paper is higher than that of another part of paper or cylinder paper.

4、紙經(jīng)豫熱器的（包角）受熱面長度挑選和調(diào)節(jié)不妥或（包角）受熱面長度不能恣意調(diào)節(jié)。前者因為操作不妥，后者因為設備局限性，影響了預熱烘干效果。

4. The length of heating surface (wrap angle) of paper heater is not properly selected and adjusted, or the length of heating surface (wrap angle) cannot be arbitrarily adjusted. The former is due to improper operation, and the latter is due to the limitation of equipment, which affects the effect of preheating and drying.

5、不能正確使用蒸汽噴霧設備或設備上無噴霧設備，因而不能恣意增加紙的濕度。

5, it is not possible to use steam spray equipment or equipment without spray equipment properly, so that humidity of paper can not be arbitrarily increased.

6、紙經(jīng)預熱后散發(fā)水分時刻缺乏或環(huán)境濕度大、通風差、出產(chǎn)線速度不妥。

6. The paper is short of moisture after preheating, or the environment humidity is high, the ventilation is poor, and the production line speed is improper.

7、單面瓦楞機、涂膠機的上膠量不妥、不均而引進紙板收縮不均。

7. Single side corrugating machine, gluing machine on the amount of improper, uneven and uneven shrinkage of the imported paperboard.
