Cartons need to do the following related testing items, each of which are related to the detection of quality assurance carton, the carton detection equipment to detect what significance does Kunshan Haida important instrument here to give you a detailed analysis?:
1, meaning compression strength tests: a direct impact on supporting strength corrugated boxes, corrugated boxes bear the gravity mainly by flute, while pressure is the best way to assess the strength of the flute;
The main factors affecting the compressive strength of corrugated board edge: the production process of corrugated board, corrugated board structure, shaped flute corrugated board, corrugated adhesive impact.
Defined edge compressive strength: in the corrugated direction, a certain height (25mm) of corrugated cardboard, unit length (100mm) can bear vertical uniform increase (12.5mm / min) of the force, known as the compression strength of corrugated board .
2, bursting strength test meaning: the impact of the side support strength corrugated boxes - corrugated protection products, bursting cardboard assessment unit that is uniform and increase the area can withstand the maximum pressure value. The test is the ability to squeeze static local investigation cartons bear in actual transport environment;
Definition of bursting strength: the maximum pressure of corrugated board per unit area can withstand even the increased value of bursting strength of corrugated board.
3, meaning strength puncture test: resistance to external examination board can withstand sudden impact energy;
Puncture strength Definition: pyramidal shaped through the work done corrugated board, called the energy displayed puncture strength of corrugated board.
4, the adhesive strength test of significance: insufficient adhesion strength is likely to cause delamination, greatly reducing the carton compressive strength;
Definition of adhesion strength: corrugated cardboard surface, where the degree of adhesion flute peak waveform corrugated core paper and, in a certain unit length isolated test can withstand the maximum peel force.
5, meaning the thickness of the test: If the cardboard processing, corrugated height loss is too large, for example through cutting, namely creasing, slotting or printed, will be greatly reduced. Cartons compressive strength, thus maintaining the thickness of the corrugated board production process should be focused grasp of a ring;
Define the thickness of the test: corrugated board under certain pressure shown by the height that is known thickness.
6, the compressive strength of corrugated boxes significance: assessment carton can withstand the maximum pressure value, carton packaging products designed to protect the strength, verify that cartons can withstand stacking weight;
Defined compressive strength of corrugated boxes: a force to increase the displacement produced uniform compression boxes, cartons are able to withstand the maximum force called compressive strength.
Qualified to determine the compressive strength: When the measured sample box of three anti-stress values are larger than the standard anti-stress value, the test is qualified; if there is a kind of box which failed, then the test is failed.
7. Other tests: flat crush strength test (ISO3035) (64.5cm2 32.2cm2 can withstand the force per unit area)
Bending stiffness test (IS05628) (four-point stiffness calculated deformation force)
Surface splashing degrees (JIS-P8137) (refer splash of standard board)
Vertical compressive strength test (JIS-Z0403-2) (special fixtures, special cutter)
Moisture resistance test (GJB1109A) (250mm * 250mm 4 pieces, 50 degrees 90% RH 48h, before and after the water is not more than 5%.
