How to Understand the Inspection Report of Laminated Floors (Part 1)
To evaluate the quality of a reinforced floor, it is actually difficult for ordinary consumers to judge it from its appearance or feel. At this time, a reinforced floor inspection report from the Provincial Institute of Product Quality Supervision and Inspection is particularly important. It can be said that it is the first basis for us ordinary people to choose reinforced floors. But its professionalism also makes it difficult for many people to understand other parts besides the test results and conclusions. Today we will talk about how to understand the inspection report of laminated flooring.
Firstly, in order to understand the inspection report, it is necessary to clarify the meaning represented by each inspection item, and secondly, the impact of the numerical value. Among them, the standard definition of static bending strength refers to the ratio of bending moment to bending section modulus of reinforced flooring under maximum static load. It reflects the ability of reinforced flooring to resist bending damage, and the larger the value of this indicator, the stronger the ability to resist bending.
The moisture content reflects the moisture content in the reinforced floor. In this indicator, if it is too high, it will cause the reinforced floor to deform easily, and if it is too low, it will easily crack. However, generally speaking, as long as it meets national standards, it is sufficient.
The standard definition of internal bonding strength refers to the ratio of the maximum load that a specimen fails to the loaded area under tensile load perpendicular to the plate surface. It reflects the quality of the bonding between the internal fibers of the reinforced floor substrate, and is an important indicator to measure the quality of the reinforced floor. If this indicator is too low, it is easy to cause layering problems in the reinforced floor, reducing its service life.
The water absorption thickness expansion rate actually represents its water resistance performance. The standard definition is the percentage increase in thickness of the specimen after soaking in water at a certain temperature for a specified time compared to the original thickness. So, the lower the value of this indicator, the better the water resistance performance of the reinforced floor, which can effectively reduce the probability of problems such as swelling and arching during use.
