重型紙箱,氣象因素:梅雨季節(jié),天氣潮濕,空氣中濕度高時(shí),原紙和波紋直接接觸空氣會(huì)吸引空氣中的濕度,直到相等,所以在這個(gè)季節(jié),無論是董事會(huì)工廠,或者一個(gè)
重型瓦楞紙箱廠家會(huì)收到投訴,甚還罰款,賠償。等一下,因?yàn)槲覀儾荒軓母旧辖鉀Q這個(gè)問題,我們都在努力解決這個(gè)問題。
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. 紙板材料:原紙和瓦楞紙,尤其是瓦楞紙,材料差,吸水力強(qiáng);紙?jiān)诳諝庵斜┞读撕荛L一段時(shí)間,當(dāng)它與空氣中的濕度平衡時(shí),紙板變得柔軟,這是不可避免的,但我們經(jīng)常這樣說。FIDEN是指坑紙,因?yàn)榭蛹堃话悴蝗缑婕埡鸵r紙、天然木材好。質(zhì)量差,吸水性強(qiáng),對(duì)瓦楞紙板有壓縮、緩沖、沖壓等物理效果,一旦變軟,我們就用手指去夾、折、沉,整塊板都是軟的。
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.
生產(chǎn)工藝:由于天氣無法控制,更換后的材料,視生產(chǎn)工藝而定。我們知道,紙板需要預(yù)熱才能實(shí)現(xiàn)干燥、起皺和粘貼、搭接立交橋、紙板離線干燥、離線風(fēng)干等生產(chǎn)過程,在預(yù)熱的中間可以輕松實(shí)現(xiàn)干燥。改變料漿配方和防水添加劑可以減少軟化現(xiàn)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.
貯存環(huán)境:放線后,應(yīng)抽出紙板,使其熱量未散失,以免因冷凝而造成溫度差。存放紙箱或紙箱時(shí)應(yīng)通風(fēng)、換氣。紙板箱不應(yīng)直接放置在地面上,并由襯墊(托盤、膠合板)支撐。應(yīng)注意它們之間的空隙,以便通風(fēng)散熱。
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、運(yùn)輸環(huán)境:較的運(yùn)輸是一個(gè)必要的過程,普通的小貨車和貨車,后者比前者可以保護(hù)紙板干燥,避免和減少軟化。
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.
六重紙箱,紙箱加工工藝:瓦楞紙板從紙板流水線上經(jīng)過4-6小時(shí)后進(jìn)入下一道工序是適宜的,此時(shí)紙板已完全成型,在印刷、沖壓等成形過程中不會(huì)改變物理性能。報(bào)復(fù)。換句話說,瓦楞紙板的質(zhì)量此時(shí)是穩(wěn)定的。經(jīng)過數(shù)小時(shí)的“內(nèi)部調(diào)整”,瓦楞紙板的組合強(qiáng)度、斷裂強(qiáng)度、邊緣抗壓強(qiáng)度、厚度恢復(fù)到極點(diǎn),含水率平衡,儲(chǔ)存環(huán)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.
當(dāng)然,儲(chǔ)存時(shí)間也取決于瓦楞紙板所用的材料。如果瓦楞紙板中的纖維又短又硬,一定要在短時(shí)間內(nèi)把線盡快轉(zhuǎn)入下道工序。否則會(huì)出現(xiàn)斷線、折疊、斷裂等質(zhì)量問題。在春夏秋冬干燥氣候條件下,當(dāng)存放時(shí)間超過6小時(shí)時(shí),應(yīng)特別注意紙板的脫水,這會(huì)導(dǎo)致成型過程中的質(zhì)量事故。在夏季,高溫和雪紙板吸收空氣中的水分,以達(dá)到與環(huán)境的水平衡,紙板變得柔軟,抗壓強(qiáng)度急劇下降。
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,建議3級(jí)紙板廠不要儲(chǔ)存太多的材料,因?yàn)檫@樣會(huì)大大增加軟化的可能性。另一方面,這也是一次采購失敗。讓明天上午生產(chǎn)的紙板今天下午到,下午生產(chǎn)的紙板中午到,這樣可以有效的避免軟化,因?yàn)闇?zhǔn)確。在多方面受到影響的情況下,我們將盡量保持供貨暢通。
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.
紙箱生產(chǎn)過程中不可避免地會(huì)產(chǎn)生紋波損傷,主要有壓輪、預(yù)壓輪、印刷區(qū)、模切區(qū)等,容易造成紙板的紋波損失,即剛性、軟化。這是無法避免的,否則紙板就不能進(jìn)行包裝,在生產(chǎn)中避免重復(fù)印前或超量印前,保持紙板平整,減少印刷內(nèi)容的塌陷,模切海綿越少越好。
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.
