STUDY OF CAPILLARY PROPERTIES OF GLASS-FIBER PAPER
Abstract
The studies of regularities have been carried out and the main variable factors of water movement in capillary-porous fiberglass materials have been established. This is the radius of the capillary and the contact angle of wetting. The main factors that determine the movement of water through the capillaries and the laws of their influence were determined. It is established that the effective radius of the capillaries, the contact angle and the strength of the glass-fiber paper depend on the diameter of the glass fiber, the type and amount of binder, the molding regimes. Calculations of the dependence of the height of water rise in the capillaries on the mean radius and hydrophilicity for 4-th values of the capillary radius and the wetting contact angle are performed.
