Brief introduction of precautions when using glue
- 2019-11-18-

Box glue is used more and more in the current printing and packaging industry. The principle of use is to choose different glues according to the different surface treatments of color box paper. So what do we need to pay attention to when using it? Today Shandong Ruiyi Yinghua New Materials Co., Ltd. will introduce you.

When you use it, you need to choose, according to the different surface data of the film to choose different glue. For example, PET or OPP film should use different paper and plastic water in the paste box; if the paper surface is bonded to the oily appearance, please use UV color box glue; if the paper surface is bonded to the polished surface, the paste box needs paste . Manual paste boxes or devices with slow paste boxes should use open time (from the moment the glue and adhesive contact the adhesive cannot move freely) long glue; automatic paste boxes or paste box speeds should use open quick-drying Paste glue.

Please pay attention to the surrounding environment and temperature when using glue. The ratio of glue used in winter and glue used in summer should be different, because the same batch of glue of the same brand is at different ambient temperatures. The viscosity is also different. The lower the ambient temperature, the higher the consistency of the glue. Whether it is winter or summer, the glue needs to reach the glue in the production process of the glue box * to strengthen the viscosity of the production operation. Due to the low temperature in winter and the high consistency of the glue, if the color box manufacturer adds water to adjust the viscosity of the glue, the adhesive strength of the glue will be affected. Therefore, the glue used at lower ambient temperature should adhere to the adhesive force of the glue and the normal reaction mechanism of the glue. It is necessary to adjust the detection system and the instrument to prepare the glue, which is why many applications are more complicated and cannot be used directly in the north.

In addition, we also need to consider the environment in which the color box is used. If the corrugated cardboard box after pasting the box needs to be sent to a high temperature environment, the color box after pasting the box needs to be sent to a low temperature environment, and then the low temperature paste box glue is needed. If the automatic folder gluer is equipped with a spray gun, you need to select the corresponding glue. Also consider the function of the gun control system. If the spray gun control system is a hot melt method, you need to use hot melt glue; if the paste box glue spray gun control system does not require heating, you need to use cold spray glue.
