現(xiàn)如今，社會(huì)經(jīng)濟(jì)發(fā)展迅速，說(shuō)起紙箱，我們大家都不會(huì)覺(jué)得陌生，因?yàn)榧埾湓谖覀兊娜粘Ｉ钪袑?shí)在是太常見(jiàn)了。實(shí)際上，紙箱已經(jīng)成為了我們生活中不可缺少的一部分了。然而對(duì)于紙箱的生產(chǎn)過(guò)程，許多人可能并不是很了解。下面我們就一起來(lái)看看紙箱是怎樣生產(chǎn)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)計(jì)算出下層紙箱所能承受的大堆碼載荷Ps
1) Calculate the maximum stacking load PS that the lowest carton can bear
即Ps=(Nmax-1)·G，其中，Nmax為大堆碼層數(shù)，G為內(nèi)裝物和箱體重。
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)選取合適的系數(shù)K
2) Select the appropriate safety factor K
根據(jù)SN/T0262-93出口運(yùn)輸包裝瓦楞紙箱檢驗(yàn)規(guī)程的要求，在貯存期小于30天時(shí)，K=1.6;貯存期在30～100天時(shí)，K=1.65;貯存期大于100天時(shí)，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.
當(dāng)然，為了起見(jiàn)，系數(shù)通常取3以上。不過(guò)系數(shù)取得過(guò)大，原材料的各種指數(shù)相對(duì)要高，紙張的會(huì)明顯上升，致使成本增加，對(duì)市場(chǎng)開(kāi)發(fā)不利。再有如果系數(shù)選取過(guò)大，會(huì)出現(xiàn)質(zhì)量過(guò)剩，系數(shù)過(guò)小，又造成塌箱等質(zhì)量問(wèn)題。所以，要根據(jù)客戶的實(shí)際要求，選取合適的系數(shù)。
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)根據(jù)系數(shù)計(jì)算出所要達(dá)到的大抗壓強(qiáng)度值P
3) According to the safety factor, calculate the maximum compressive strength p
即P=K·Ps
Namely P=K. Ps
4)根據(jù)Kelicutt公式，選擇合適的紙張搭配組合
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(xiàn)為與紙箱周邊長(zhǎng)和瓦楞型有關(guān)的常數(shù)，通過(guò)查表得出。Px為瓦楞紙板綜合環(huán)壓強(qiáng)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中任何一種或兩種材料的環(huán)壓指數(shù)和克重，便可求出第三種材料的環(huán)壓指數(shù)和克重，達(dá)到紙張合理搭配的目的。
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.
