The Influence of Printing Paste of Cardboard Box Corrugated Cardboard on Different Surfaces

Wave surface curvature effect

The high-temperature paste is a starch gelatinized cooked glue as a carrier to form a mixture of various ingredients. There is a lot of moisture in the paste itself. In the paste of wavy and face paper, there is a lot of moisture in the paste. This kind of water is the need of instant reaction, and it also affects the corrugated paperboard, and fits together. Balance the strength and adjust the effect. Comparing the same operation mode and the same condition speed: A: The paste on the paste has a large gap, the B-cell paste has a relatively small interval, and the paste has a sparse and dense pattern. In theory, the B-wave has a paste. More pulp, the comparison of moisture content has a larger surface balance force effect, and A wave impact is relatively small, that is to say: the impact of the change in the ratio of the B vehicle paste size is more sensitive. Since the A car crash wave is higher than the B wave, the sharpness of the warming of the bottom surface of the A wave is also smaller than that of the B wave in the paperboard bonding. Therefore, the relative change in contraction force is also smaller.

Effect of Paste on the Exterior of Irregular Wave Surface

For some materials, the same material, sometimes B car surface smoother, and A car surface is easy to produce small bubbles, become rough. The vesicles form a convex bubble between peaks. This state A car is significantly larger, B car is weak, this effect is a change in the thickness of the paste, but the material, the material's flexibility is the fundamental change, so the size of the paste has a certain change Suppression surface, compared to the two Lang, A car distance, large material change space, change the shape of the intensity, the degree of smoothness of the A car compared to the B car.

The Effect of Paste on Rupture Strength

The thickness of the paste affects the pressure and damage of the paper, and at the same time it has a certain degree of influence on the rupture value formed. Thickening of the paste leads to an increase in the moisture content of the water. The increase in water content leads to a reduction in the strength of the paper, resulting in a greater damage rate of the base paper strength under the strong pressure of the fitting bottom wheel. Comparing A and B, at the same speed and same conditions, A car has more elastic force and speed increasing pressure, so the impact of the paste on the A car breakdown value is more sensitive to B car.
