Paper and board - Determination of peel strength between layers
1 Scope
This standard specifies the test method for measuring the peel strength between layers of paper and paperboard.
This standard applies to the determination of a variety of Lin Mozhi, composite paper and cardboard thickness greater than 0.5mm layer of peel strength, does not apply to corrugated
cardboard.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 450 paper and cardboard samples taken and the vertical and horizontal, positive and negative determination
GB/T 10739 Standard atmospheric conditions for the handling and testing of paper, board and pulp specimens
Determination of tensile strength of paper and board GB/T 12914-2008
3 principle
One end of the sample is peeled off in advance by a certain length, and the peeled part is sandwiched between the two ends of the tensile strength testing machine respectively. At a predetermined speed
Degree of peel force was applied to record the peel force curve during peel, calculate the average peel force within the specified chuck displacement.
4 equipment
Tensile strength testing machine shall comply with the requirements of 5.2.1 of GB/T 12914-2008 and equipped with peel force curve recording device. recording
Device should be able to record the chuck displacement from 0mm ~ 150mm peel force curve, and with data acquisition and processing software, data acquisition
The frequency shall ensure that at least 100 data are collected between 25 mm and 125 mm from the chuck and the data processing software shall be capable of peeling
25mm chuck displacement before and after the test data removed, and can calculate the average chuck chuck displacement from 25mm ~ 125mm
The peel strength was calculated using the average peel force.
5 sample
According to GB/T 450 provisions for sampling.
6 temperature and humidity treatment
Samples should be GB/T 10739 temperature and humidity treatment, and in this atmospheric conditions to prepare samples and test.
Note. Under normal circumstances, the temperature and humidity treatment time of 24h, quantitative high, thick cardboard can be properly extended processing time.
7 Sample Preparation
