THE EFFECT OF DECORATIVE COATINGS BY MIXING OF POLY VINYL ACETATE AND UREA- FORMALDEHYDE ON PHYSICAL AND MECHANICAL PROPERTIES PARTICLEBOARD

The Effect of Decorative Coatings by mixing of Poly Vinyl Acetate and Urea- Formaldehyde on Physical and Mechanical Properties Particleboard

In this study the effect of adhesive types and coated veneer on the physical and mechanical properties of particleboard were studied.Two types of coating, including natural veneer of beech and artificial veneer of High Paper Lamination (HPL, formica) and three types of adhesive composition including (100 % UF), (15% PVA + 85 % UF) and (25% PVA + 75

Measurement of Cerenkov Radiation Induced by the Gamma-Rays of Co-60 Therapy Units Using Wavelength Shifting Fiber

In this study, a wavelength shifting fiber that shifts ultra-violet and blue light to green light was employed as a sensor probe of a fiber-optic Cerenkov radiation sensor.In order to characterize Cerenkov radiation generated in the developed wavelength shifting fiber and a plastic optical fiber, spectra and intensities of Cerenkov radiation were m
