在冬季干燥的天氣里，紙箱生產(chǎn)爆箱的問(wèn)題困擾著許多
紙箱廠家，不僅嚴(yán)重影響了紙箱的質(zhì)量，損失率急劇上升，而且還會(huì)延誤發(fā)貨，使紙箱廠家?guī)?lái)嚴(yán)重的經(jīng)濟(jì)損失。通過(guò)不斷的探索，總結(jié)出一些從控制水分到提高爆線的方法，希望對(duì)大家有所幫助。
In the dry weather in winter, the problem of box explosion in the production of cartons perplexes many cartons manufacturers, which not only seriously affects the quality of cartons, but also delays the delivery of goods, causing serious economic losses to cartons manufacturers. Through continuous exploration, summed up some methods from the control of moisture to improve the burst line, hope to help you.
一、明確:紙箱爆裂的根本原因是什么?
1、 Clear: what is the root cause of the carton bursting?
瓦楞紙板的含水率是影響紙箱爆裂的關(guān)鍵因素
The moisture content of corrugated board is the key factor affecting the bursting of the box
紙是一種親水材料，吸水時(shí)會(huì)變軟變硬，失水會(huì)變硬變脆。當(dāng)紙板含水率較低時(shí)，水分對(duì)瓦楞紙箱爆裂的影響主要表現(xiàn)在兩個(gè)方面:
Paper is a kind of hydrophilic material, which will become soft and hard when absorbing water, and hard and brittle when losing water. When the moisture content of cardboard is low, the influence of moisture content on the bursting of corrugated box is mainly manifested in two aspects:
1. 內(nèi)紙的耐折性降低，硬紙板的剛度增加，紙箱破裂的可能性增加
1. The folding resistance of inner paper is reduced, the rigidity of cardboard is increased, and the possibility of carton cracking is increased
2. 紙板芯的平壓強(qiáng)度增加，紙張表面的韌性下降，在壓線時(shí)容易損壞紙張表面，導(dǎo)致紙箱爆裂。
2. The flat compression strength of the cardboard core increases, the toughness of the paper surface decreases, and the paper surface is easy to be damaged when pressing the line, resulting in the bursting of the carton.
二、找到緩解爆線的方法，控制水分是關(guān)鍵
2、 The key to find a way to relieve the burst line is to control the moisture content
保持瓦楞紙板的含水率，是控制紙板線條的佳方法。瓦楞紙板的含水率從瓦線控制在12 ~ 18%的范圍內(nèi)，含水率保持在10 ~ 13%的范圍內(nèi)。由于一些客觀條件，人們往往認(rèn)為控制
Keeping the moisture content of corrugated board is the best way to control the line of board. The moisture content of corrugated board is controlled within 12 ~ 18% from the tile line, and the moisture content is kept within 10 ~ 13%. Because of some objective conditions, people often think that control
它不容易制造水。在這里，我們將介紹一些更有效的方法:
It's not easy to make water. Here, we will introduce some more effective methods:
1. 調(diào)整瓦楞紙板的加工工藝
1. Adjust the processing technology of corrugated board
傳統(tǒng)的瓦楞紙板加工工藝調(diào)整方法是有效的。一般來(lái)說(shuō)，我們可以采取以下方法來(lái)控制:
The traditional adjustment method of corrugated board processing technology is effective. Generally speaking, we can take the following measures to control:
(1)制漿時(shí)，適當(dāng)調(diào)整膏體配方，增加膏體含水量。
(1) During pulping, the paste formula should be adjusted properly to increase the water content of paste.
(2)增加膏體用量。實(shí)踐證明，增加糊劑用量能有效提高紙板的含水率，增加糊劑用量也能在一定程度上改善粘接效果。
(2) Increase the dosage of paste. It has been proved that the increase of paste content can effectively improve the moisture content of paperboard, and the increase of paste content can also improve the bonding effect to a certain extent.
(3)適當(dāng)減少原紙與預(yù)熱輪的接觸面積，避免預(yù)熱筒上的水過(guò)度蒸發(fā)。
(3) Properly reduce the contact area between the base paper and the preheating wheel to avoid excessive evaporation of water on the preheating cylinder.
(4)減少紙板在熱板上的停留時(shí)間。通過(guò)保持高速、縮短熱板的長(zhǎng)度、降低熱板的蒸汽壓力等方式避免紙板在熱板中通過(guò)過(guò)度蒸發(fā)水分。當(dāng)使用這種方法時(shí)，必須小心確保板不離開(kāi)坑。
(4) Reduce the retention time of cardboard on the hot plate. By keeping high speed, shortening the length of the hot plate and reducing the steam pressure of the hot plate, the excessive evaporation of water in the hot plate can be avoided. When using this method, care must be taken to ensure that the plate does not leave the pit.
2. 紙板制作后應(yīng)堆放足夠的時(shí)間后再進(jìn)行機(jī)器打印
2. The cardboard shall be stacked for enough time before printing
對(duì)紙板從瓦線出來(lái)的時(shí)間和紙板在機(jī)器上印刷的時(shí)間之間的水分變化規(guī)律缺乏了解是造成爆線的一個(gè)重要原因。
One of the important reasons for the burst is the lack of understanding of the law of moisture change between the time when the paperboard comes out of the tile line and the time when the paperboard is printed on the machine.
當(dāng)紙板從瓦片線出來(lái)時(shí)，雖然整體含水率較高，但每層紙的含水率極不平衡。天氣是干燥的季節(jié)，紙板剛生產(chǎn)出來(lái)時(shí)紙板的表面含水量約為8%，有的甚低于6%，當(dāng)紙板堆放4小時(shí)后，每層紙的水分趨于平衡，表面紙的水分增加到9%以上。所以如果紙板剛從瓦楞紙機(jī)上打印出來(lái)，因?yàn)橥呃慵埖谋砻嫠趾艿?，很容易?dǎo)致壓力線爆裂。
When the paperboard comes out of the tile line, although the overall moisture content is high, the moisture content of each layer of paper is extremely unbalanced. The weather is dry season, when the cardboard is just produced, the surface moisture content of the cardboard is about 8%, some even lower than 6%. When the cardboard is stacked for 4 hours, the moisture content of each layer of paper tends to balance, and the moisture content of the surface paper increases to more than 9%. So if the paperboard is just printed out of the corrugating machine, because the surface moisture of the corrugating paper is very low, it is easy to cause the pressure line to burst.
改進(jìn)方法:
Improvement method:
1. 紙板生產(chǎn)后應(yīng)堆放足夠的時(shí)間，待每層紙的水分達(dá)到平衡后，將其打印在機(jī)器上。如果紙板和襯紙的含水量較低，它就會(huì)印在線條上，線條就會(huì)微微開(kāi)裂，那么即使表面和襯紙的含水量增加，線條爆炸的問(wèn)題也是無(wú)法避免的。
1. The paperboard shall be stacked for enough time after production, and printed on the machine after the moisture of each layer of paper reaches the balance. If the moisture content of paperboard and liner is low, it will be printed on the line, and the line will slightly crack, so even if the moisture content of the surface and liner increases, the problem of line explosion is inevitable.
2. 如果發(fā)貨時(shí)間太短，沒(méi)有足夠的時(shí)間使紙板水分平衡，濕水到紙板表面是直接有效的方法。潮濕的水好避免影響印刷現(xiàn)場(chǎng)，否則會(huì)對(duì)印刷造成不利影響。如果條件允許，可以使用磨損的野外版
2. If the delivery time is too short and there is not enough time to make the water balance of the cardboard, wet water to the cardboard surface is the most direct and effective method. Wet water is best to avoid affecting the printing site, otherwise it will cause adverse effects on printing. If conditions permit, a worn field version can be used
要制做濕版，先用印臺(tái)把線打濕，然后再打印。這樣，可以快速的將生產(chǎn)線壓濕，而且不影響印刷質(zhì)量。
To make a wet plate, first wet the line with the printer, and then print. In this way, the production line can be quickly pressed wet, and does not affect the printing quality.
