This paper is using borax as Crosslinking agent to make starch solution and use NaOH to decrease the temperature of starch glue. The viscosity of starch glue get under control with corrugated cardboard adhesive process into pipes and those glue are free to flow. We also disscuss about the control of nonglued time and the effect of gluing in process. We spread same quantity of the solutions on a corrugated paper which is 5cm long and 2cm wide. After the corrugated paper is dried, we start to survey its physical tensile strength and the viscosity of the starch solution.
The research knew, the starch glue is reaction time longer viscosity to be bigger. Especially in four hours the viscosity rises slowly, 6 hours later the viscosity rises hurriedly. And using pure corn starch makes the starch glue, and mounts it on the corrugated cardboard. The viscosity is bigger, the adhesive strength is then bigger. This research mix Topioca by 1:2, 2:1 proportion. And the starch glue makes by the pure Topioca sticks the fluid by way of tensile testing machine analysis. Know that the Topioca mix are more, the intensity is then bigger. And the starch glue by the pure Topioca have most greatly adhesive strength.
