Corrugated corrugated corrugated corrugated cardboard has a different function of bonded corrugated board. Even if the same quality of facial paper and paper is used, the performance of the corrugated paperboard formed has a certain difference due to the difference in shape.
The common corrugated shapes in the world are divided into four types: Type A, Type C, Type B, and Type E.
Their technical indicators and requirements are analyzed below:
The corrugated cardboard made of A type ramie has good cushioning and is full of certain elasticity;
Type C is better than Type A, but its stiffness and impact resistance are better than Type A.
The B-type crucible has a high density of arrangement, and the corrugated paperboard made of a smooth surface has a high bearing pressure and is suitable for printing.
Because of its thinness and denseness, the E-type cymbal shows its rigidity.
The following is the table for each type, height, and number of turns:
楞 type - 楞 high, mm - 楞 number, each / 300mm
A—4.5 to 5—34±2
C——3.5～4—38±2
B—2.5 to 3—50±2
E——1.1～2——96±4
Second, corrugated corrugated shape corrugated corrugated cardboard corrugated corrugated shape is divided into V-shaped, U-shaped and UV-shaped.
The corrugated V-shaped waveform features a high plane pressure resistance value, which saves adhesive usage and saves corrugated base paper during use. However, corrugated cardboard made of corrugated corrugated board has poor cushioning properties, and the corrugated board is not easily restored after being subjected to pressure or impact.
The corrugated U waveform features a large area of glue, a strong bond, and a certain degree of elasticity. When impacted by an external force, it is not as fragile as a V-shaped raft, but the plane pressure is not as strong as a V-shaped raft.
According to the performance characteristics of the V-shaped crucible and the U-shaped crucible, a UV-shaped corrugating roll manufactured by synthesizing the advantages of the two has been commonly used. The processed corrugated corrugated paper not only maintains the high pressure resistance of the V-shaped crucible, but also has the high adhesive strength of the U-shaped crucible and is rich in certain elasticity.
