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.
