It is the goal pursued by every carton enterprise to produce excellent corrugated cardboard with a semi-automatic box gluing machine, but there are often a considerable proportion of enterprises whose production quality is unsatisfactory.
How to improve the quality of corrugated paperboard is a topic of common concern in the packaging industry. The following will explain how to improve the quality of corrugated paperboard from the aspects of adjustment of adhesives and glue rollers and the amount of glue, pressure and temperature.
Semi-automatic glue box machine must control its physical and chemical indexes to make high-quality adhesives, such as the ratio of starch to water, the viscosity of the finished adhesive, fluidity, PH value, gelatinization temperature, etc. Changes in these indicators will have a great impact on the bonding strength and flatness of the cardboard.
The main raw material of the adhesive is starch. The quality of starch has a direct impact on the quality of the adhesive. If poor quality starch is selected as the raw material, the viscosity and fluidity of the finished adhesive will be unstable, so , We must strictly control the quality when purchasing starch.
The quality of the adhesive production process also has a direct impact on the quality of the cardboard. In order to reduce the production cost of the adhesive theoretically, some companies will increase the ratio of water to starch during the production process, but the semi-automatic box gluer In the production of cardboard, in order to achieve adhesive strength, the amount of glue will be increased blindly. We know that starch is mainly used by the adhesive to bond the cardboard. Water is only a linking material. It is unscientific to reduce the production cost of the adhesive by increasing the ratio of water to starch. This will not only reduce the cost, On the contrary, it will have a serious impact on the quality of the cardboard, so that the various testing indicators can not meet the ideal requirements.
