Heavy cartons, weather factors: in rainy season, when the weather is humid and the humidity in the air is high, the base paper and corrugations will directly contact the air to attract the humidity in the air until they are equal, so in this season, whether it is the board factory or a carton factory will receive complaints, even pay fines and compensation. Wait a minute, because we can't solve this problem fundamentally. We are all trying to solve this problem.

　　2. 纸板材料:原纸和瓦楞纸，尤其是瓦楞纸，材料差，吸水力强;纸在空气中暴露了很长一段时间，当它与空气中的湿度平衡时，纸板变得柔软，这是不可避免的，但我们经常这样说。FIDEN是指坑纸，因为坑纸一般不如面纸和衬纸、天然木材好。质量差，吸水性强，对瓦楞纸板有压缩、缓冲、冲压等物理效果，一旦变软，我们就用手指去夹、折、沉，整块板都是软的。

　　2. Cardboard material: base paper and corrugated paper, especially corrugated paper, have poor material and strong water absorption; paper has been exposed in the air for a long time, when it is in balance with the humidity in the air, cardboard becomes soft, which is inevitable, but we often say so. Fiden refers to pit paper, because pit paper is generally not as good as face paper, lining paper and natural wood. Poor quality, strong water absorption, compression, buffering, stamping and other physical effects on corrugated board. Once it becomes soft, we use our fingers to clamp, fold, sink, and the whole board is soft.

　　生产工艺:由于天气无法控制，更换后的材料，视生产工艺而定。我们知道，纸板需要预热才能实现干燥、起皱和粘贴、搭接立交桥、纸板离线干燥、离线风干等生产过程，在预热的中间可以轻松实现干燥。改变料浆配方和防水添加剂可以减少软化现象。

　　Production process: due to the uncontrollable weather, the replaced material depends on the production process. We know that cardboard needs preheating in order to achieve the drying, wrinkling and pasting, overlapping overpass, cardboard offline drying, offline air drying and other production processes. Drying can be easily achieved in the middle of preheating. The softening phenomenon can be reduced by changing the slurry formula and waterproof additives.

　　贮存环境:放线后，应抽出纸板，使其热量未散失，以免因冷凝而造成温度差。存放纸箱或纸箱时应通风、换气。纸板箱不应直接放置在地面上，并由衬垫(托盘、胶合板)支撑。应注意它们之间的空隙，以便通风散热。

　　Storage environment: after setting out, the cardboard shall be drawn out so that the heat is not lost, so as to avoid the temperature difference caused by condensation. When storing cartons or cartons, ventilate them. Cartons should not be placed directly on the ground and supported by liners (pallets, plywood). Pay attention to the space between them for ventilation and heat dissipation.

　　五、运输环境:较的运输是一个必要的过程，普通的小货车和货车，后者比前者可以保护纸板干燥，避免和减少软化。

　　5、 Transportation environment: lower transportation is a necessary process. Ordinary pickup trucks and trucks, the latter can protect cardboard from drying, avoid and reduce softening.

　　六重纸箱，纸箱加工工艺:瓦楞纸板从纸板流水线上经过4-6小时后进入下一道工序是适宜的，此时纸板已完全成型，在印刷、冲压等成形过程中不会改变物理性能。报复。换句话说，瓦楞纸板的质量此时是稳定的。经过数小时的“内部调整”，瓦楞纸板的组合强度、断裂强度、边缘抗压强度、厚度恢复到极点，含水率平衡，储存环境良好。

　　Six fold carton, carton processing technology: it is suitable for corrugated cardboard to enter the next process after 4-6 hours from the cardboard assembly line. At this time, the cardboard has been fully formed, and the physical properties will not be changed during the printing, stamping and other forming processes. Payback. In other words, the quality of the corrugated board is stable at this time. After several hours of "internal adjustment", the combined strength, breaking strength, edge compressive strength and thickness of corrugated board are restored to the pole, the moisture content is balanced, and the storage environment is good.

　　当然，储存时间也取决于瓦楞纸板所用的材料。如果瓦楞纸板中的纤维又短又硬，一定要在短时间内把线尽快转入下道工序。否则会出现断线、折叠、断裂等质量问题。在春夏秋冬干燥气候条件下，当存放时间超过6小时时，应特别注意纸板的脱水，这会导致成型过程中的质量事故。在夏季，高温和雪纸板吸收空气中的水分，以达到与环境的水平衡，纸板变得柔软，抗压强度急剧下降。

　　Of course, the storage time also depends on the material used in the corrugated board. If the fiber in the corrugated board is short and hard, the line must be transferred to the next process as soon as possible in a short time. Otherwise, quality problems such as breakage, folding and fracture will occur. In the dry climate of spring, summer, autumn and winter, when the storage time is more than 6 hours, special attention should be paid to the dehydration of cardboard, which will lead to quality accidents in the forming process. In summer, high temperature and snowboard absorb the moisture in the air to achieve the water balance with the environment. The paperboard becomes soft and the compressive strength drops sharply.

　　因此，建议3级纸板厂不要储存太多的材料，因为这样会大大增加软化的可能性。另一方面，这也是一次采购失败。让明天上午生产的纸板今天下午到，下午生产的纸板中午到，这样可以有效的避免软化，因为准确。在多方面受到影响的情况下，我们将尽量保持供货畅通。

　　Therefore, it is recommended not to store too many materials in grade 3 cardboard factory, because this will greatly increase the possibility of softening. On the other hand, it is also a failure of procurement. Let the paperboard produced tomorrow morning arrive this afternoon, and the paperboard produced in the afternoon arrive at noon, which can effectively avoid softening, because it is accurate. We will try our best to keep the supply as smooth as possible in the case of multiple impacts.

　　纸箱生产过程中不可避免地会产生纹波损伤，主要有压轮、预压轮、印刷区、模切区等，容易造成纸板的纹波损失，即刚性、软化。这是无法避免的，否则纸板就不能进行包装，在生产中避免重复印前或超量印前，保持纸板平整，减少印刷内容的塌陷，模切海绵越少越好。

　　In the production process of cartons, ripple damage will inevitably occur, mainly including pressing wheel, pre pressing wheel, printing area, die-cutting area, etc., which is easy to cause ripple loss of cardboard, that is, rigidity and softening. This can not be avoided, otherwise the cardboard can not be packaged, in production to avoid repeated pre press or excessive pre press, keep the cardboard flat, reduce the collapse of printing content, the less die-cutting sponge, the better.
