Glossiness

Carbon disulphide is an excellent solvent for fats, oils, rubber, sulphur, bromine and iodine, and is used industrially as a solvent for extraction. It is also used in the production of viscose silk, when added to wood cellulose impregnated with sodium hydroxide solution, a viscous solution of cellulose xanthate is formed, and this can be extruded through a fine nozzle into acid, which decomposes the xanthate to give a glossy thread of cellulose. 

Fluidyibsorbamy. Fluids like ink penetrate into paper during the printing process. The further the ink penetrates, the less glossy the print. The degree of penetration in paper is generally a function of the paper porosity and wettabiUty by the fluid. It can be controlled by the particle size, shape, and chemical nature of the filler or filler surface. In particular, plate-like fillers, such as clays, tend to produce the best fluid holdout because they tend to overlap and reduce the porosity at the paper surface (see Inks).

Pigment-coated printing papers usually are required to have high brightness to achieve contrast between the printed and unprinted areas. The coatings frequendy have a glossy surface. There also is a demand for duU-coated papers and for dull papers upon which glossy ink films can be printed. 

Hydrogels. Controlled swelling of hydrophilic polymers, derived from the glossy/mbbery properties of polymers, is used to control the rate of dmg release from matrices. In the mbbery state, accompHshed by lowering the polymer s glass-transition temperature to an appropriate level, the dispersed dmg diffuses as the polymer swells in the presence of water. 

In both the Hquid and vapor states, phosphoms(III) oxide exists as the P40 molecule. The vapor of phosphoms(III) oxide ionizes air. Phosphoms tetroxide is made by heating P40 in a sealed tube to 440°C. P40 sublimes under vacuum at I80°C and forms colorless, glossy crystals. 

Drawdown from the die to nip is typically ca 10%. Sheet extmsion requires that the resin be of high melt viscosity to prevent excessive sag of the melt between the die and the nip. The melt should reach the nip before touching any other part of the middle roU to prevent uncontrolled cooling of the resin. The appearance of the lower surface of the sheet is deterrnined by the middle roU, ie, its poHsh, surface temperature, and freedom from condensed materials. The upper surface is cooled by air and has a more glossy appearance. Neither the top roU nor the bottom roU greatly affect the appearance of the top surface of the sheet. Edges of the sheet are trimmed.

Eyeliners are available in two popular forms. One of these is a deeply pigmented emulsion that is appHed with a fine bmsh. The emulsion must be viscous to avoid miming and should dry to a waterproof film. The emulsion can be patterned after the emulsions used in mascaras. Glossy eyeliners require the use of nacreous pigments suspended in polymeric film formers, for example, acryUc acid copoljmiers.

For higher rating systems, say 2500 A and above, sleeving is normally not used. Instead, a non-metallic, semi-glossy black paint may be provided to make the bus conductors act like a black body and dissipate more heat. This will also add to the current-carrying... 

A regenerative absorbent consisting of the amorphous silica manufactured by the action of MCI on sodium silicate. Hard, glossy, quartz-like in appearance. Used in dehydrating and in drying and as a catalyst carrier. 

The glossy side is tighter and fully wetted, designed to stay with the PSA.
