The effect of ozone treatment on change in single fiber strength, fiber surface morphology, whiteness, moisture absorbency, etc was studied.
We examined how working techniques, e.g., floor top finishing and curing and the resulting pore distribution on the concrete floor slab surface related to water absorbency and the water content of study specimens.
Apart from economic considerations, the usefulness of a fibre for commercial purposes is determined by such properties as length, strength, pliability, elasticity, abrasion resistance, absorbency, and various surface properties.
However, many properties, such as surface texture, color, strength, stretch, absorbency, permeability, translucency, grease or moisture resistance, electrical conductivity, permanency, and stiffness, can be imparted by carefully tailoring the manufacturing process.
"This is slightly narrower than the Saracens pitch, but in terms of the shock absorbency and the surface it's very similar".
Water-absorbency at the surface of ACCs also reduced significantly with increasing dissolution time during preparation of ACCs, imparting slight hydrophobicity in the ACC-laminates prepared by using 2 h or more dissolution time.
· Tom Meek is available for commissions ([email protected], 01795 522531) Key Materials · Use a good quality watercolour or handmade paper with a smooth, hot-pressed surface and the right level of absorbency, so the inks don't bleed.
Predictions of A-weighted excess attenuation for a traffic noise spectrum are made illustrating the effects of varying the depth of the cutting and the absorbency of the surrounding ground surface.
The best single measure of acoustic performance for auditoriums is the reverberation time, which is directly proportional to the volume of the hall and inversely proportional to the amount of sound absorbency within it, including wall and ceiling surfaces and the audience itself.
It has been demonstrated that converting fibers into particles increases the material surface area, resulting in significant improvements in their reactivity and absorbency, which have promoted the applications of fibrous materials in both textile and non-textile fields [30 32].
