It is the goal of every carton enterprise to make excellent corrugated board by Semi-Automatic folding gluing machine, but the quality of products produced by a considerable proportion of enterprises is difficult to be satisfactory. How to improve the quality of corrugated board is a common concern of the packaging industry. The following will explain how to improve the quality of corrugated board from the aspects of adhesive, the adjustment of cots and the amount of glue, pressure, temperature and so on.
1. Making high-quality adhesive must control its physical and chemical indexes, such as the proportion of starch to water, the viscosity, fluidity, PH value and gelatinization temperature of the finished adhesive. The change of these indexes will have a great effect on the adhesive strength and flatness of the paper board;
2.the main raw material of semi-automatic adhesive box adhesive is starch, the quality of starch has a direct impact on the quality of adhesive. If the starch with poor quality is selected as raw material, the viscosity and liquidity of finished adhesive will be unstable, so we must strictly control the quality when we choose and purchase starch.
3.The advantages and disadvantages of adhesive production technology also have a direct impact on the quality of paperboard. In order to reduce the production cost of adhesive in theory, some enterprises will increase the ratio of water to starch in the production process, but in order to achieve the bonding strength, the semi-automatic adhesive box machine will blindly increase the amount of glue in the production of paperboard. We know that starch is the main adhesive to paperboard, water is only link auxiliary material, if you want to increase the ratio of water to starch to reduce the production cost of adhesive is not scientific, so that not only can not reduce the cost, but will have a serious impact on the quality of paperboard, so that the testing index can not meet the ideal requirements.
