现如今，社会经济发展迅速，说起纸箱，我们大家都不会觉得陌生，因为纸箱在我们的日常生活中实在是太常见了。实际上，纸箱已经成为了我们生活中不可缺少的一部分了。然而对于纸箱的生产过程，许多人可能并不是很了解。下面我们就一起来看看纸箱是怎样生产的吧。
Nowadays, with the rapid development of social economy, speaking of cartons, we will not feel strange, because cartons are so common in our daily life. In fact, cartons have become an indispensable part of our life. However, many people may not know the production process of cartons very well. Let's take a look at how cartons are made.
1)计算出下层纸箱所能承受的大堆码载荷Ps
1) Calculate the maximum stacking load PS that the lowest carton can bear
即Ps=(Nmax-1)·G，其中，Nmax为大堆码层数，G为内装物和箱体重。
That is PS = (nmax-1) · g, where nmax is the maximum number of stacking layers, and G is the weight of contents and boxes.
2)选取合适的系数K
2) Select the appropriate safety factor K
根据SN/T0262-93出口运输包装瓦楞纸箱检验规程的要求，在贮存期小于30天时，K=1.6;贮存期在30～100天时，K=1.65;贮存期大于100天时，K=2。
According to the requirements of Sn / t0262-93, k = 1.6 when the storage period is less than 30 days; k = 1.65 when the storage period is 30-100 days; k = 2 when the storage period is more than 100 days.
当然，为了起见，系数通常取3以上。不过系数取得过大，原材料的各种指数相对要高，纸张的会明显上升，致使成本增加，对市场开发不利。再有如果系数选取过大，会出现质量过剩，系数过小，又造成塌箱等质量问题。所以，要根据客户的实际要求，选取合适的系数。
Of course, for the sake of safety, the safety factor is usually more than 3. However, if the safety factor is too large, the indexes of raw materials will be relatively high, and the price of paper will rise significantly, which will increase the cost and be detrimental to market development. Moreover, if the safety factor is too large, there will be excessive quality, too small coefficient and quality problems such as box collapse. Therefore, the appropriate safety factor should be selected according to the actual requirements of customers.
3)根据系数计算出所要达到的大抗压强度值P
3) According to the safety factor, calculate the maximum compressive strength p
即P=K·Ps
Namely P=K. Ps
4)根据Kelicutt公式，选择合适的纸张搭配组合
4) According to kelicutt formula, choose the right paper mix
即Px·F=P(已算出)
That is, PX · f = P (calculated)
所以Px=P/F，其中，F为与纸箱周边长和瓦楞型有关的常数，通过查表得出。Px为瓦楞纸板综合环压强度值，Px=(R1+R2+Rm1C)/15.2
So PX = P / F, where f is the constant related to the length of the carton periphery and the corrugated type, which is obtained by looking up the table. PX is the comprehensive ring compression strength of corrugated board, PX = (R1 + R2 + rm1c) / 15.2
如果已知R1、R2、Rm1C中任何一种或两种材料的环压指数和克重，便可求出第三种材料的环压指数和克重，达到纸张合理搭配的目的。
If the ring pressure index and g-weight of any one or two materials in R1, R2 and rm1c are known, the ring pressure index and g-weight of the third material can be calculated, so as to achieve the purpose of reasonable paper matching.
The above is the main production process of cartons. Do you know that?
