上光、覆膜是兩種不同的工藝。上光是對(duì)印刷品表面涂布上光油，罩上一層亮膜，和平工藝比較簡單，成本也低，但效果不及覆膜好。覆膜是用熱壓加工方法在印刷品表面粘貼一層聚乙烯或聚丙烯薄膜，形成一種紙塑合層的印刷品，具有十分良好的光亮度和耐磨性能。覆膜板采用高溫壓制復(fù)合而成，它的致密性和強(qiáng)度都很高，韌性也很好。與木材相比，其靜態(tài)彎曲強(qiáng)度是木材的兩倍以上。覆膜板幅寬，拼接部位少，與鋁鋼模板相比，支撐和拆卸速度會(huì)快很多。同時(shí)，其建設(shè)成本會(huì)相對(duì)較低，可以有效縮短工期。另外，這種材料的重量更輕，剪釘性能會(huì)更好，所以使用起來非常方便，速度也會(huì)更快。覆膜板耐水性強(qiáng)，在制造過程中，每層都使用酚醛樹脂，然后熱壓，因此面板使用后不易變形。同時(shí)，其導(dǎo)熱系數(shù)遠(yuǎn)低于鋼膜，因此無論是夏季還是冬季都可以正常施工。
Upper light and film coating are two different processes.The light is to paint the surface of the printing product with light oil, covering a bright film, the peace process is relatively simple, the cost is also low, but the effect is not as good as the film.Cover film is a layer of polyethylene or polypropylene film pasted on the surface of the printing product, forming a paper-plastic layer of printed product, with very good brightness and wear resistance.The film cover plate is made of high temperature suppression composite, it is very high density and strength, the toughness is also very good.Its static bending strength is more than twice that of wood.The coating plate is wide and has less splicing parts, and the support and disassembly speed will be much faster than the aluminum steel formwork.At the same time, its construction cost will be relatively low, which can effectively shorten the construction period.In addition, the material is lighter and cuts the nails better, so it is very easy to use and is faster.The coated plate has strong water resistance. During the manufacturing process, phenolic resin is used in each layer, and then hot pressure, so the panel is not easy to deformation after use.At the same time, its thermal conductivity is much lower than the steel film, so whether in summer or winter can be normal construction.
