How To Calculate Bursting Factor Of A Paper

What

is bursting strength:

Bursting

strength is the maximum pressure on the surface

of the paper or paperboard that is perpendicular to the surface of the specimen

under the experimental conditions. Bursting strength of carton reflects the

circulation in the process of handling, loading and unloading, impact and tear

strength capacity, is one of the comprehensive evaluation of the performance of

the carton.

Factors

of affecting fracture strength:

The

bursting strength of corrugated box is composed of

the inner and outer layers of cardboard and paper itself septum bursting

strength, has nothing to do with the corrugated paper. The paper is mainly

decided by the bursting strength of paper fiber. The breaking resistance is

related to the length of fiber and the binding force between fibers, and the

increase of fiber length and the increase of the bonding force between the

fibers can improve the fracture resistance. Wood pulp paper bursting with high

recovery of pulp, paper pulp coniferous forest with hardwood pulp high breaking

resistance. In addition, in the process of making paper adding some additives

also helps to improve the bursting strength of paper.

how

to calculate bursting factor of a paper:

The principle of empirical formula is

the bursting strength of corrugated paper in the paper, and is equal to the

bursting strength of paper septum and multiplied by a certain coefficient, but

has nothing to do with the bursting strength of corrugated paper.

Empirical formula for calculating

bursting strength of paperboard:

P=0.92 sigma sigma B

In type:

P is the bursting strength of corrugated

board

Breaking strength for resistance to

sigma B in the paper, paper and paper of the middle segment

Sigma total

Because of the difference between

batches, base stacking time and storage environment will cause certain

influence on bursting strength, so there will be some estimated value and the

true value of error analysis, the test data statistics, the error was less than

1.0Kg. We should also be included in the calculation of the resistance and the

strength of the paper should be included in the scope of consideration.
