Phenolic plate quality problems
most of the phenolic plate in the process of actual use, there will be a lot of different quality problem that you know they have appeared quality problem is what are the reasons?
from now to Chou, phenolic board such a kind of the product itself is composed of a variety of different chemical composition, and their porosity also determines the bibulous rate of the whole product, after absorbing the phenolic plate, if excessive and dry, so they will reduce the quality of, the extent of the powder can also be in constant degradation, and their compression strength will also gradually become smaller, even paste sex is more or less will be affected by a series of, this certainly will affect the entire product performance, they also after absorbing water, the degree of the powder can also be gradually intensified, slowly once appears to protect the surface cracking, will enter into it, thus erosion to phenolic board.
in these phenolic plate, of course, the process of the practical use, because they have the strength of itself is very low, so the tear of the external force is more or less will be caused damage, its strength is low, can't guarantee the reliability of the paste, that on the whole structure will be in existence for this series of cavity, this time of stress, is inevitably a series of loss happens to lightly, stronger, to paste the force they basically also may be torn apart and destroy some of the structure.
now basically these phenolic board size, of course, will affect their quality, and can be better used in exterior wall insulation construction, even under certain conditions will make them happen deformation, so the stability of volume is not particularly, accumulated variables will be very big.
