Spin dry

Ambler [1979] reports the equations below for the equilibrium liquor contents Sw and the instantaneous value St, obtaining at any time t during the spin the constants and depend on the material processed  

The exponent x on the cake thickness is reported in the range 0.5 x 1.0 for relatively inconq ressible cakes e onenty on the spin time takes values in the range 0.3 y 0.5. 

Other work [Wakeman, 1976] points to a general relationship for the residual saturation of coarse granular particles  

Later worir [Wakeman, 1979] demonstrated that the above information may be rqrresaited by equations of the form  

A uup break in the drainage curve is noticeable as the drainage force increases (increase in iVc 0.14) this may be due to breakdown of retention forces leading to a p dular state in the liquor between particles.

One report (13) describes the procedure for spinning dry asymmetric ceUulose acetate fiber with a bore skin. Such fibers are spun in a modified dry-spinning process in which a volatile Uquid (methyl formate) is used as the ceUulose acetate solvent. The bore coagulating Uquid is isopropyl alcohol, which is subsequentiy removed. The advantages of these dry fibers over most ceUulose acetate membranes are that they can be stored dry, they are wet-dry reversible, they can be sterilized and packed dry, and they are ready for use without removal of preservatives. 

Spin dry at 500 rpm for 5 min at room temperature. The slides are ready for scanning. Store the dried slides in dark box until scanning. 

Neither flash nor spin-drying produces highly uniform particles and, even though the bulk of the particles remain at or near the wet bulb temperature, small particles are often over-dried and overheated. Particles of uniform size can be formed by spray drying, however, although it is then necessary that the feed should be in the form of a pumpable liquid which can be atomised so that the particles are evenly exposed to the hot air.

Although melt-spinning would be preferred from the standpoint of process simplicity and conversion cost, aramids must be spun from solutions, by wet, dry, or dry jet-wet methods because they decompose before or during melting, ruling out melt spinning. Dry-spinning... 

It is easy to chimge the polished poly Si hydrophobic surface to hydrc hilic surface by organic surfactant inclut g silica particles during water polish. Because, the wafin surfece was covered with organic film. This organic tilm was easy to remove by anode water rinse and spin dried. 

Hybridization components such as SDS and SSC fluoresce and, unless washed from the slide surface prior to scanning, will cause diffuse low-level background. This background can be minimized by immediately spin-drying slides by low-velocity centrifugation after washing. Washing is based on standard hybridization protocols. 

This indicates that disturbances in the frequency band below qc will grow more rapidly as ho shrinks. As long as T in is much smaller than the time required for resist spinning, drying, and curing, disturbances will grow exponentially and rupture the film before it has a chance to solidify. This also suggests that the number of pinhole-type defects in UTR films may scale with I/Ziq.
