瓦楞紙箱是一種應(yīng)用廣泛的包裝制品，用量一直是各種包裝制品之一。以其優(yōu)越的使用性能和良好的加工性能逐漸取代了木箱等運(yùn)輸包裝容器，成為運(yùn)輸包裝的主力軍。它除了保護(hù)商品、便于倉儲(chǔ)、運(yùn)輸之外，還起到美化商品，宣傳商品的作用。而在瓦楞紙箱上光操作中，有必要嚴(yán)格承認(rèn)以下幾點(diǎn)，方可保證瓦楞紙箱防潮上光質(zhì)量合格：
Corrugated box is a kind of widely used packaging products, the dosage has been one of the various packaging products. With its superior performance and good processing performance, it has gradually replaced wooden boxes and other transport packaging containers and become the main force of transport packaging. It not only protects the goods, facilitates storage and transportation, but also beautifies and publicizes the goods. In the Polish operation of corrugated box, it is necessary to strictly admit the following points in order to ensure the moisture-proof Polish quality of corrugated box
1：油墨：需要留意涂料與油墨的結(jié)合問題，必要時(shí)先涂一層膠。
1: Ink: need to pay attention to the combination of paint and ink, if necessary, first apply a layer of primer.
2：涂層厚度：上光涂層經(jīng)過紫外光輻射后光引發(fā)劑被引發(fā)，會(huì)產(chǎn)生游離基或離子，這些游離基或離子與預(yù)聚體或不飽和單體中的雙鍵起交聯(lián)反應(yīng)，構(gòu)成單體基。這些單體基會(huì)經(jīng)過連鎖反應(yīng)生成聚合體固體高分子，完成上光涂料的干燥過程。涂布層過厚，在相同功率光源的照耀下干燥時(shí)間相對長，一方面影響上光油的干燥，另一方面使紙張的含水量相對削減，會(huì)使張紙變脆易斷，影響油層的耐磨性。
2: Coating thickness: after UV radiation, photoinitiator is initiated to produce free radicals or ions. These free radicals or ions react with double bonds in prepolymer or unsaturated monomer to form monomer group. These monomers will produce polymer solid polymer through chain reaction to complete the drying process of glazing coating. Coating layer is too thick, in the light of the same power light source drying time is relatively long, on the one hand, affect the drying of varnish, on the other hand, the water content of the paper is relatively reduced, will make the paper brittle and easy to break, affect the wear resistance of oil layer.
3：光源：UV照耀光源一般采用高壓汞燈或金屬鹵化物燈（以無極燈為佳），光源的功率也要求安穩(wěn)。高壓汞燈的輸出功率一般為80～120W/cm，才干保證涂料的固化速度小于0.5s。
3: Light source: UV light source generally adopts high pressure mercury lamp or metal halide lamp (electrodeless lamp is better), and the power of the light source is also required to be stable. The output power of high-pressure mercury lamp is generally 80 ~ 120W / cm, which can ensure the curing speed of the coating is less than 0.5s.
4：紙張涂料不適合對容易浸透的紙張進(jìn)行加工，由于涂猜中的分子資料簡單浸透到紙張中，引起紙張的變暗乃浸透。這種情況下，只要加速印刷速度，并增加燈管數(shù)量。為了防止浸透現(xiàn)象，可先用紅外在層進(jìn)行涂布，以避免上涂料時(shí)出現(xiàn)浸透現(xiàn)象
4: The paper coating is not suitable for the paper which is easy to be soaked. Because the low molecular data in the coating can be easily soaked into the paper, the paper will be darkened or even soaked. In this case, as long as the printing speed is accelerated and the number of lamps is increased. In order to prevent the phenomenon of penetration, you can first use the infrared bottom coating in the bottom layer to avoid the phenomenon of penetration when coating
5：稀釋劑：上光油一般來說需運(yùn)用專用稀釋劑，稀釋量控制在1:0.51:1左右，過多則會(huì)影響上光效果（具體視涂膜量而定）。
5: Diluent: glazing oil generally need to use special diluent, dilution control in 1:0.5 to 1:1, too much will affect the glazing effect (depending on the amount of film).
6：黏連（未干透）：涂布太厚，應(yīng)下降黏度；燈功率缺乏或老化，應(yīng)替換UV燈使之到達(dá)額定功率。
6: Adhesion (not completely dry): if the coating is too thick, the viscosity should be reduced; if the lamp power is insufficient or aging, the UV lamp should be replaced to reach the rated power.
7：平滑度不佳：上光機(jī)涂布輥筒損壞或上光油黏度高，應(yīng)替換或重磨輥簡，下降上光油黏度。
7: Poor smoothness: glazing machine coating roller damage or high viscosity, should replace or regrinding roller, reduce the viscosity of the varnish.
8：上光亮度差：若濟(jì)南瓦楞紙箱紙張質(zhì)量差或外表粗糙、吸油量大，應(yīng)改用高一檔紙張；涂布不均勻或上光油稀釋太薄、黏度過，應(yīng)調(diào)整上光機(jī)及進(jìn)步上光油黏度；附著力差，印刷品油墨層晶化或油墨添加劑及防滑劑等運(yùn)用不當(dāng)，應(yīng)改進(jìn)印刷工藝，不用或少用油墨添加劑；上光油黏度太，應(yīng)調(diào)整上光機(jī)及進(jìn)步上光油黏度。
8: Poor gloss: if the paper quality of Jinan corrugated box is poor or the appearance is rough and the oil absorption is large, a higher grade paper should be used; if the coating is uneven or the varnish dilution is too thin and the viscosity is too low, the polishing machine should be adjusted and the varnish viscosity should be improved; if the adhesion is poor, the printing ink layer crystallization or the ink additive and antiskid agent are not used properly, the printing process should be improved, and the oil should not be used or less Ink additives; on oil viscosity is too low, you should adjust the machine and progress on oil viscosity.
9：上光層發(fā)白：交聯(lián)密度。稀釋劑運(yùn)用不當(dāng)，因夏天醇類溶劑蒸發(fā)速度快，應(yīng)替換稀釋劑或改用酯類稀釋劑。
9: White layer: low cross-linking density. If the diluent is not used properly, because the evaporation speed of alcohol solvent is fast in summer, the diluent should be replaced or the ester diluent should be used instead.
10：涂布層偏黃：上光油涂層太厚，黏度偏大，應(yīng)下降黏度；上光油過期（運(yùn)用期限一般為6個(gè)月），應(yīng)停止運(yùn)用。
10: Coating layer yellow: too thick varnish coating, viscosity, should reduce viscosity; glazing oil expired (use period is generally 6 months), should stop using.
